COVID-19 as a viral disease has brought up the need to exercise more than before due to its physiological effects on health. Therefore, this study investigates the effect of 12-week of aerobic exercise on female students' hormone levels and lipid profile with polycystic ovary syndrome (PCOS) during the COVID-19 pandemic.. Using a 12-week quasi-experimental with pretest, posttest research design among 40 Iranian female students aged 18-14 with PCOS, we randomly allocated the participants to either an experimental (they performed aerobic exercises three 60-minute sessions per week at home using content production) or a control condition. Their anthropometric and blood samples (e.g., testosterone, estrogen, prolactin, and lipid profile) were taken in two stages before and after the training protocol.. Findings demonstrated that performing aerobic exercises is an effective and non-invasive method that could have a positive effect on young girls' PCOS during COVID-19 pandemic.. La pandémie de COVID-19, en tant que maladie virale, a fait ressortir la nécessité de faire de l’exercice plus que jamais en raison de ses effets physiologiques sur la santé. Par conséquent, cette étude examine l’effet de 12 semaines d’exercice aérobique sur les niveaux hormonaux et le profil lipidique d’étudiantes atteintes du syndrome d’ovaires polykystiques (SOPK) pendant la pandémie de COVID-19.. En utilisant un modèle de recherche quasi-expérimental de 12 semaines avec pré-test, post-test auprès de 40 étudiantes iraniennes âgées de 18 à 14 ans atteintes du SOPK, nous avons réparti au hasard les participantes entre une série expérimentale (elles ont effectué des exercices aérobiques à raison de trois séances de 60 minutes par semaine à la maison) et une série contrôle. Les échantillons anthropométriques et sanguins (testostérone, œstrogène, prolactine et profil lipidique) ont été prélevés en deux étapes, avant et après le protocole d’entraînement.. Les résultats ont démontré que la pratique d’exercices d’aérobic est une méthode efficace et non invasive qui pourrait avoir un effet positif sur le SOPK des jeunes filles pendant la pandémie de COVID-19.. Our research showed that even less than 5 GBq irradiation could induce a transient testicular dysfunction in the first 3 months of therapy, but it was mostly reversible after 12 months..

Embelin is predicted to have a high probability of immunotoxicity potential and affect drug metabolism by inhibiting CYP2D6. In addition, it affects food intake, weight gain, and the number of implantations in pregnant rats. Therefore, it is highly recommended not to take embelin and embelin-rich plants during pregnancy.

This study ascribes for a new immunomodulatory role for IL11 during tumor development that is amenable to anti-cytokine based therapy of colon cancer.. Inflammation response do not seem to be enough to explain all the Essure-related adverse outcomes, suggesting the involvement of other biological mechanisms.. NCT03281564.. Inflammation and fibrosis are found in the surrounding tubal tissue around the Essure. Adult patients with BED with co-occurring obesity who have good responses to acute treatment with naltrexone/bupropion should be offered maintenance treatment with naltrexone/bupropion.. dp/dtmax in PiCCO parameter can be used as a bedside indicator to evaluate cardiac function in SIC patients due to its simplicity and ease of operation. Esmolol control of heart rate in SIC patients can improve cardiac function and reduce short-term mortality.. Inverted microscopy showed that compared with the NC group, the OGD/R group had poor cell status, swollen cytosol, visible cell lysis fragments and significantly lower cell activity [(49.1±2.7)% vs. (100.0±9.7)%, P < 0.01]; compared with the OGD/R group, the HW group had improved cell status and remarkably higher cell activity [(63.3±1.8)% vs. (49.1±2.7)%, P < 0.01]. Transmission electron microscopy showed that the neuronal nuclear membrane of cells in the OGD/R group was lysed and a higher number of autophagic lysosomes were visible compared with the NC group; compared with the OGD/R group, the neuronal damage of cells in the HW group was reduced and the number of autophagic lysosomes was notably decreased. The results of immunofluorescence assay showed that the expressions of LC3 and Beclin-1 were outstandingly enhanced in the OGD/R group compared with the NC group, and the expressions of LC3 and Beclin-1 were markedly weakened in the HW group compared with the OGD/R group. Western blotting assay showed that the expressions were prominently higher in both LC3II/I and Beclin-1 in the OGD/R group compared with the NC group (LC3II/I: 1.44±0.05 vs. 0.37±0.03, Beclin-1/β-actin: 1.00±0.02 vs. 0.64±0.01, both P < 0.01); compared with the OGD/R group, the protein expression of both LC3II/I and Beclin-1 in the HW group cells were notably lower (LC3II/I: 0.54±0.02 vs. 1.44±0.05, Beclin-1/β-actin: 0.83±0.07 vs. 1.00±0.02, both P < 0.01).. Hydrogen-rich water has a significant protective effect on OGD/R-causing HT22 cell injury, and the mechanism may be related to the inhibition of autophagy.. The prevalence of delirium in ICU patients is over 50%, with hypoactive delirium being the most common. Age, APACHE score at ICU admission, neurological disease, sepsis and duration of mechanical ventilation were all independent risk factors for the development of delirium in ICU patients. More than half of patients with delirium were still delirious when they discharged from the ICU.. For individuals ≥75 years, plasma Aβ42 and P-tau181 might not be associated with cognitive impairment, and MRI parameters, including PVWMH, LVBI and cortical atrophy, are related to CI. The cognitive statuses of people over 75 years old were used as the endpoint event in this study. Therefore, it can be considered that these MRI markers might have more important clinical significance for early assessment and dynamic observation, but more studies are still needed to verify this hypothesis.. We recommend using the Art/Zn complex owing to its moderate inhibitory and antiviral effects against the SARS-CoV-2 with a low cytotoxic effect on host (Vero E6) cells. We suggest conducting further prospective studies to investigate the biological effects of Art/Zn in animal models at different concentrations for testing its clinical efficacy and safety in inhibiting SARS-CoV-2 activities.. The R/T sequence resulted in a significantly longer OS and PFS and improved disease control compared with the reverse sequence. R and T given not sequentially have similar impacts on survival. More data are needed to define the best sequence and to explore the efficacy of sequential (T/R or R/T) treatment combined with molecular-targeted drugs.

Patients with inflammatory bowel diseases (IBD) have a high risk of colitis-associated dysplasia and cancer. It is important that careful surveillance with colonoscopy is performed for all patients with IBD and, more frequently, for those considered to be at high risk. Traditionally, flat dysplasia in ulcerative colitis has been considered to be detectable only by using random biopsy specimens of mucosa that appeared unremarkable during endoscopy. However, recent studies have shown that most of them are visible; thus, their detection as nonpolypoid colorectal neoplasms is an integral component in the prevention of colitic cancer.

The indication of endoscopic submucosal dissection for Barrett's esophageal adenocarcinoma (BEA) is superficial BEA without lymph node metastasis. The characteristic endoscopic findings of superficial BEA are elevation, depression, and color change. Indigocarmine spreading is useful for the diagnosis of lateral extension. It is a simple and easy enhancement method. The observation of surface and vascular pattern by magnifying endoscopy with narrow-band imaging is also useful for the diagnosis of lateral extension. The incidence of gastric cancer is high in Japan. The majority of early gastric cancer is detected by conventional endoscopy without random biopsy, or target biopsydiagnosis. The background mucosa of gastric cancer has gastritis, and the carcinogenesis based on inflammation is the same as early BEA. However, random biopsy remains the universal standard for early detection of Barrett's high-grade dysplasia and superficial BEA. A surveillance system that does not use random biopsy can and should be established using high-resolution endoscopy with target biopsy.

Given its morbidity and mortality, the early detection and diagnosis of gastric cancer is an area of intense research focus. This article reviews the emerging use of enhanced endoscopic imaging technologies in the detection and management of gastric cancer. The combined use of white-light endoscopy with enhanced imaging technologies, such as magnification narrow-band imaging, chromoendoscopy, and autofluorescence endoscopy, demonstrates promise in the improved ability to detect and delineate gastric neoplasia. However, widespread clinical use is still limited, mainly because of the restricted availability of the technologies.

Patients with Lynch syndrome (LS) undergo regular surveillance by colonoscopy because of an increased risk of colorectal neoplasia, particularly in the proximal colon. Chromoendoscopy (CE) has been reported to improve neoplasia detection compared with conventional white-light endoscopy (WLE), but evidence is limited. Our aim was to investigate the effect of CE in the proximal colon on detection of neoplastic lesions during surveillance in LS.. This was a multicenter prospective randomized controlled trial of 246 patients with LS who were randomly assigned (1:1) to conventional WLE (n = 123) or colonoscopy with CE in the proximal colon (n = 123), stratified for previous colorectal adenomas and enrolling center. Two years after baseline colonoscopy, patients underwent colonoscopy with CE in the proximal colon. The primary outcome was the proportion of patients with at least one neoplastic lesion at baseline and after 2 years.. Neoplasia detection rates at baseline colonoscopy were 27% for WLE versus 30% for CE (odds ratio [OR], 1.23; 95% confidence interval [CI], 0.69-2.2; P = .56). In the proximal colon, neoplasia detection rates were 16% for WLE versus 24% for CE (OR, 1.6; 95% CI, 0.9-3.1; P = .13). Total procedure time was 9 minutes longer in the CE group. At follow-up after 2 years, neoplasia detection rates were similar in both groups: 26% for the original WLE group versus 28% for the CE group (OR, 1.1; P = .81).. CE in the proximal colon for LS surveillance was not superior to WLE with respect to the initial detection of neoplasia, and not associated with reduced neoplasia detection rates after 2 years. The value of CE remains to be established. (Clinical trial registration number: NCT00905710.).

Endoscopic mucosal resection (EMR) is an effective therapeutic technique well-standardized worldwide for the treatment of gastrointestinal neoplasm limited to the mucosal layer. To date, no study has compared technical and clinical differences based on the number of EMRs performed per year. This study aimed to compare EMR technical success, complications, and clinical outcome between low-volume centers (LVCs) and high-volume centers (HVCs). A total of nine endoscopic centers were included in the study.. This prospective study investigated consecutive patients with sessile polyps or flat colorectal lesions 1 cm or larger referred for EMR.. A total of 427 lesions were resected in 384 patients at nine endoscopic centers. Males accounted for 60.4% and females for 39.6% of the patients. Most of the EMRs (84.8%) were performed in HVCs and only 15.2% in LVCs. All the lesions were resected in only one session. Argon plasma coagulation was performed on the margins of piecemeal resection in 15.7% of the patients in HVCs only. Complete excision was achieved for 98.6% of the lesions in HVCs and 98.8% of the lesions in LVCs. The complication rate was 4.4% in HVCs and 4.6% in LVCs (p = 0.94). Delayed bleeding occurred in 2.5% of the HVC cases and 3.1% of the LVC cases. Perforation occurred in 1.9% of the HVC cases and 1.5% of the LVC cases (p = 1.00). Recurrences were experienced with 15% of the lesions: 15.5% in HVCs and 14% in LVCs (p = 0.79).. The study showed that EMR can be performed also in LVC.

Endoscopic submucosal dissection (ESD), a new widely accepted method for treating early gastric cancer, was developed to increase the en bloc rate, especially for lesions larger than 20 mm in diameter. This study aimed to evaluate the efficacy and safety of ESD for colorectal epithelial neoplasms.. From July 2006 to December 2007, ESD was indicated for patients with colorectal epithelial neoplasms larger than 20 mm in diameter. The rates of curative en bloc resection, the procedure time, and the incidence of complications were investigated.. A total of 74 colorectal epithelial neoplasms were resected by ESD. The mean diameter of these lesions was 32.6 mm (range, 20-85 mm). The rate of en bloc resection was 93.2% (69/74), and the mean ESD procedure time was 110 min (range, 80-185 min). None of patients had massive hemorrhage during ESD, and only one patient (1.4%) bled 8 days after ESD. Six patients experienced perforation, and all except one recovered after several days of conservative treatment. The patient who did not recover underwent urgent surgery. The perforation rate was 8.1% (6/74). All the patients were followed up. Healing of the artificial ulcer was confirmed, and with no lesion residue or recurrence was found.. The findings show ESD to be effective for colorectal epithelial neoplasm, making it possible to resect the whole lesion in one piece and to provide precise histologic information.

Endoscopic submucosal dissection (ESD) has been developed as treatment for early gastric cancer (EGC) by Japanese authors. However, there are no reports about its possible implementation in the Western setting. The aim of the present work is to determine the safety and efficacy of the endoscopic treatments for EGC in an Italian cohort.. Forty-five patients for a total of 48 gastric lesions were enrolled in the study. Thirty-six EMR procedures were performed with the strip biopsy technique using a double-channel endoscope. En bloc resection refers to resection in one piece, while piecemeal refers to resections in which the lesion was removed in multiple fragments. A total of 12 ESD were performed and completed with IT knife. We define as curative treatment lateral and vertical margins of the resected specimens free of cancer and repeat endoscopic finding of no recurrent disease.. Out of 36 EMR procedures, 10 were piecemeal resections (28%), while 26 were en bloc (72%). ESD led to en bloc resection in 11/12 cases (92%). Histological assessment of curability in the EMR group was achieved in 56% of the cases, and in 92% of the ESD group. Mean follow-up period was 31 months (range: 12-71 months). There was no local recurrence or distant metastasis in the curative group patients.. These results seem to confirm the safety and the clinical efficacy of the ESD procedure in the Western world too.

To retrospectively evaluate the feasibility of CT fluoroscopy-guided percutaneous marking using a 25-gauge needle and indigo carmine before video-assisted thoracoscopic surgery (VATS) for small lung lesions.. 21 patients, 14 males and 7 females, with a median age of 69 years (range, 40-79), underwent CT fluoroscopy-guided percutaneous VATS marking using a 25-gauge, 70-mm needle and 1.5-ml indigo carmine. The mean diameter of the lung lesions was 14 mm (range, 6-27). We evaluated the technical success rate, surgical success rate and complications related to this procedure by reviewing medical records and images. Technical success was defined as completion of this procedure. Surgical success was defined as resection of the target lesion with negative margins on pathological examination after VATS. Complications that required advanced levels of care were classified as major complications, and the remaining complications were considered minor.. The technical success rate was 100%. In all cases, VATS was successfully performed as planned, and the target lesion was resected with negative margins on pathological examination after VATS. Thus, the surgical success rate was 100%. Mild pneumothorax was found in two cases, but further treatment was not required. The minor complication rate was 9.5% (2/21), and major complication rate was 0%. Only two patients (9.5%) complained of slight pain upon puncture, but local anaesthesia was not required.. Percutaneous CT fluoroscopy-guided VATS marking using a 25-gauge needle without local anaesthesia appears feasible and safe. Advances in knowledge: This technique expands a possibility of the CT-guided marking.

Colorectal laterally spreading tumor granular type (LST-G) is generally divided into two subtypes based on morphology. Here, we retrospectively investigated the clinical significance of a concrete, objective LST-G subclassification.. This study examined 636 consecutive cases that were resected endoscopically or surgically. LST-G was subclassified as follows: Type 1, a lesion with homogenous uniform granules with uniform (<5 mm) nodules; Type 2, a lesion with granules and small nodules (≥5 mm, <10 mm); or Type 3, a lesion accompanied by large nodules (≥10 mm). For the validation study, 194 images were compiled from 97 cases investigated using conventional colonoscopy and chromoendoscopy with indigo carmine dye spraying. Images were distributed in a randomized order to students without prior endoscopy experience, less-experienced endoscopists (LEE group), and highly experienced endoscopists (HEE group). Diagnostic accuracy and interobserver agreement were then evaluated.. There was no submucosal invasion in Type 1 lesions. The incidence of deep submucosal invasive carcinoma was higher for Type 3 lesions than for Type 2 lesions. Interobserver agreement was good in each group. Diagnostic accuracy was higher in the HEE group than in the student and LEE groups. Chromoendoscopy had a higher accuracy rate than conventional colonoscopy in the LEE and HEE groups (LEE, 0.74 vs 0.69, P < 0.05; HEE, 0.84 vs 0.78, P < 0.05).. This subclassification of LST-G according to the diameters of granules and nodules was both useful for choosing therapeutic strategies in the clinical setting and universally applicable.

To investigate the accuracy of endoscopic or biopsy diagnoses of superficial nonampullary duodenal epithelial tumors (NADETs).. Clinicopathological data were reviewed for 84 superficial NADETs from 74 patients who underwent surgery or endoscopic resection between September 2002 and August 2014 at a single prefectural cancer center. Superficial NADETs were defined as lesions confined to the mucosa or submucosa. Demographic and clinicopathological data were retrieved from charts, endoscopic and pathologic reports. Endoscopic reports included endoscopic diagnosis, location, gross type, diameter, color, and presence or absence of biopsy. Endoscopic diagnoses were made by an endoscopist in charge of the examination before biopsy specimens were obtained. Endoscopic images were obtained using routine, front-view, high-resolution video endoscopy, and chromoendoscopy with indigocarmine was performed for all lesions. Endoscopic images were reviewed by at least two endoscopists to assess endoscopic findings indicative of carcinoma. Preoperative diagnoses based on endoscopy and biopsy findings were compared with histological diagnoses of resected specimens. Sensitivity, specificity, and accuracy were assessed for endoscopic diagnosis and biopsy diagnosis.. The majority (81%) of the lesions were located in the second portion of the duodenum. The median lesion diameter was 14.5 mm according to final histology. Surgery was performed for 49 lesions from 39 patients, and 35 lesions from 35 patients were endoscopically resected. Final histology confirmed 65 carcinomas, 15 adenomas, and 3 hyperplasias. A final diagnosis of duodenal carcinoma was made for 91% (52/57) of the lesions diagnosed as carcinoma by endoscopy and 93% (42/45) of the lesions diagnosed as carcinoma by biopsy. The sensitivity, specificity, and accuracy of endoscopic diagnoses were 80%, 72%, and 78%, respectively, whereas those of biopsy diagnoses were 72%, 80%, and 74%, respectively. Preoperative diagnoses of carcinomas were made in 88% (57/65) of the carcinoma lesions via endoscopy or biopsy. Endoscopic findings associated with carcinoma were red color, depression, and mixed-type morphology.. Preoperative endoscopy and biopsy showed similar accuracies in the diagnosis of carcinoma in patients with superficial NADETs.

To investigate the usefulness of chromoendoscopy, using an acetic acid indigocarmine mixture (AIM), for gastric adenoma diagnosed by forceps biopsy.. A total of 54 lesions in 45 patients diagnosed as gastric adenoma by forceps biopsy were prospectively enrolled in this study and treated by endoscopic submucosal dissection (ESD) between January 2011 and January 2012. AIM-chromoendoscopy (AIM-CE) was performed followed by ESD. AIM solution was sprinkled and images were recorded every 30 s for 3 min. Clinical characteristics such as tumor size (< 2 cm, ≥ 2 cm), surface color in white light endoscopy (WLE) (whitish, normochromic or reddish), macroscopic appearance (flat or elevated, depressed), and reddish change in AIM-CE were selected as valuables.. En bloc resection was achieved in all 54 cases, with curative resection of fifty two lesions (96.3%). Twenty three lesions (42.6%) were diagnosed as well-differentiated adenocarcinoma and the remaining 31 lesions (57.4%) were gastric adenoma. All adenocarcinoma lesions were well-differentiated tubular adenocarcinomas and were restricted within the mucosal layer. The sensitivity of reddish color change in AIM-CE is significantly higher than that in WLE (vs tumor size ≥ 2 cm, P = 0.016, vs normochromic or reddish surface color, P = 0.046, vs depressed macroscopic type, P = 0.0030). On the other hand, no significant differences were found in the specificity and accuracy. In univariate analysis, normochromic or reddish surface color in WLE (OR = 3.7, 95%CI: 1.2-12, P = 0.022) and reddish change in AIM-CE (OR = 14, 95%CI: 3.8-70, P < 0.001) were significantly related to diagnosis of early gastric cancer (EGC). In multivariate analysis, only reddish change in AIM-CE (OR = 11, 95%CI: 2.3-66, P = 0.0022) was a significant factor associated with diagnosis of EGC.. AIM-CE may have potential for screening EGC in patients initially diagnosed as gastric adenoma by forceps biopsy.

To evaluate the usefulness of flexible spectral imaging color enhancement with indigo carmine (I-FICE) in early gastric cancer (EGC) demarcation.. The study participants were 29 patients with differentiated-type EGC. The endoscope was fixed and images of the same area of EGC demarcations in each lesion were obtained using four different methods (WLE, flexible spectral imaging color enhancement (FICE), CE, and I-FICE). FICE mode at R 550 nm (Gain: 2), G 500 nm (Gain: 4), and B 470 nm (Gain: 4) was used. Four endoscopists ranked the images obtained by each method on the basis of the ease of recognition of demarcation using a 4-point system. We calculated the standard deviation of pixel values based on L*, a*, and b* color spaces in the demarcation region (Lab-SD score).. The median ranking score for I-FICE images was significantly higher than that obtained from the other methods. Further, the average Lab-SD score was significantly higher for I-FICE images than for images obtained by the other methods. There was a good correlation between the ranking score and Lab-SD score.. EGC demarcations were most easily recognized both subjectively and objectively using I-FICE image, followed by CE, FICE and WLE images.

Endoscopic submucosal dissection (ESD) has recently been applied to the treatment of superficial colorectal cancer. Clinical outcomes compared with conventional endoscopic mucosal resection (EMR) have not been determined so our aim was to compare the effectiveness of ESD with conventional EMR for colorectal tumors >or=20 mm.. This was a retrospective case-controlled study performed at the National Cancer Center Hospital in Tokyo, Japan involving 373 colorectal tumors >or=20 mm determined histologically to be curative resections. Data acquisition was from a prospectively completed database. We evaluated histology, tumor size, procedure time, en bloc resection rate, recurrence rate, and associated complications for both the ESD and EMR groups.. A total of 145 colorectal tumors were treated by ESD and another 228 were treated by EMR. ESD was associated with a longer procedure time (108 +/- 71 min/29 +/- 25 min; p < 0.0001), higher en bloc resection rate (84%/33%; p < 0.0001) and larger resected specimens (37 +/- 14 mm/28 +/- 8 mm; p = 0.0006), but involved a similar percentage of cancers (69%/66%; p = NS). There were three (2%) recurrences in the ESD group and 33 (14%) in the EMR group requiring additional EMR (p < 0.0001). The perforation rate was 6.2% (9) in the ESD group and 1.3% (3) in the EMR group (p = NS) with delayed bleeding occurring in 1.4% (2) and 3.1% (7) of the procedures (p = NS), respectively, as all complications were effectively treated endoscopically.. Despite its longer procedure time and higher perforation rate, ESD resulted in higher en bloc resection and curative rates compared with EMR and all ESD perforations were successfully managed by conservative endoscopic treatment.

Endoscopic treatments, such as endoscopic submucosal dissection (ESD) and laparoscopic gastrectomy, are increasingly used to treat a subset of patients with early gastric cancer (EGC). To achieve successful outcomes, it is very important to accurately determine the lateral extent of the tumor. Therefore, we investigated the diagnostic performance of chromoendoscopy using indigo carmine dye added to acetic acid (AI chromoendoscopy) in delineating differentiated or undifferentiated adenocarcinomas in patients with EGC.. We prospectively included 151 lesions of 141 patients that had an endoscopic diagnosis of EGC. All the lesions were examined by conventional endoscopy and AI chromoendoscopy before ESD or laparoscopic gastrectomy. The border clarification between the lesion and the normal mucosa was classified as distinct or indistinct before and after AI chromoendoscopy.. The borders of the lesions were distinct in 66.9% (101/151) with conventional endoscopy and in 84.1% (127/151) with AI chromoendoscopy (P < 0.001). Compared with conventional endoscopy, AI chromoendoscopy clarified the border in a significantly higher percentage of differentiated adenocarcinomas (74/108 [68.5%] vs 97/108 [89.8%], respectively, P < 0.001). However, the border clarification rate for undifferentiated adenocarcinomas did not differ between conventional endoscopy and AI chromoendoscopy (27/43 [62.8%] vs 30/43 [70.0%], respectively, P = 0.494).. AI chromoendoscopy is useful in determining the lateral extent of EGCs. However, its usefulness is reduced in undifferentiated adenocarcinomas.

Detection of early gastric tube cancers (GTCs) has increased with more detailed surveillance endoscopy using indigo carmine dye following esophagectomy. This retrospective study clarified the clinicopathological features and application of endoscopic submucosal dissection (ESD) for GTCs. Data collected for eight GTCs treated by ESD included clinical and pathological features and outcomes following ESD. Overall, eight GTCs were identified in seven (6.3 %) of 112 patients who underwent esophagectomy and gastric tube reconstruction. Almost all lesions were macroscopically type 0-IIa with mucosal to submucosal invasion, and seven GTCs were successfully resected en bloc by ESD. Submucosal invasion to > 500 microm was observed in one case with associated delayed perforation that was treated conservatively. No local recurrences of GTCs were observed. Detailed surveillance endoscopy using indigo carmine dye appears useful for diagnosing early-stage GTC. Furthermore ESD represents a feasible alternative to conventional endoscopic mucosal resection as a minimally invasive therapy for early-stage GTC.

For the purpose of precise preoperative diagnosis that ensures complete endoscopic resection, it is important to accurately determine the lateral spread of gastric cancer lesions. The acetic acid + indigocarmine (AI) method used by us has been found to meet this need. This paper reports its usefulness in the determination of lateral spread of gastric cancer before endoscopic submucosal dissection (ESD).. The present study was conducted in 114 patients who were operated on for an early-stage gastric cancer, after determining the lateral spread of cancerous lesions by the AI method, between September 2005 and December 2006. The negative lateral stump reaction rate obtained in ESD was conducted in areas delineated by the AI method. The borderline clarification rate obtained by the AI method and the indigocarmine (I) method were compared between the lesions with and without clear borders under observation with the naked eye.. The lateral stump after ESD conducted using the AI method was histologically negative in 111 of the 114 patients (97%). The lesion spread was clarified by the AI method in 103 patients (90%): 55 (95%) and 48 (86%) patients with and without clear macroscopic lesion borders, respectively. Compared to the I method, the AI method clarified the lesion spread in a significantly higher percentage of patients with macroscopically unclear lesion borders (P = 0.015).. The present study stresses that the AI method should be used to conduct ESD more safely and accurately in patients with well or moderately differentiated adenocarcinoma.

This study describes the feasibility of magnifying colonoscopy with indigo carmine dye contrast to distinguish neoplastic and nonneoplastic colonic polyps. This study sampled consecutive patients undergoing colonoscopy using an Olympus CF240ZI from January to October 2000 at Chang-Gung Memorial Hospital, Lin-Kou Medical Center. This study analyzed a total of 270 polyps. Indigo carmine (0.2%) was sprayed directly on the mucosa surface before observing the crypts using a magnifying colonoscope (1.5x-100x). The pit patterns were described using the classification proposed by Kudo. Finally, polypectomy or biopsy was performed for histological diagnosis. The study identified 155 adenomas, 99 hyperplastic polyps, 9 adenocarcinomas, and 7 other nonneoplastic lesions (harmatoma, inflammatory polyps, and mucosal tag). The pit pattern was analyzed for all lesions. Further classification into neoplastic (adenoma and adenocarcinoma) and nonneoplastic (hyperplastic and others) polyps revealed 156 neoplastic and 14 nonneoplastic polyps among the type III to type V pits and 92 nonneoplastic and 8 neoplastic polyps among the type I and II pits. The sensitivity of type III to type V pits in detecting neoplastic polyps was 95.1%, with a specificity of 86.8% and diagnostic accuracy of 91.9%. The positive likelihood ratio was 7.3, and the negative likelihood ratio was 0.06. Magnifying colonoscopy with indigo carmine dye contrast provides morphological detail that correlates well with polyp histology. Small flat lesions with typical type II pit pattern should have minimal neoplastic risk, thus endoscopic resection is not necessary.

We report on a rare case of bilateral ureteral injury in a patient undergoing radical perineal prostatectomy and a unique approach to his treatment. Potential risk factors for such an injury include previous prostatic cryotherapy, transurethral resection, or radiotherapy. Intraoperative recognition of the injury is paramount and may be facilitated by intravenous administration of indigo carmine. While distal ureter ligation, urinary diversion, and delayed ureteroneocystostomy may be regarded as standard management for ureteral injury during radical perineal prostatectomy, this case was treated with a primary bilateral transperineal ureteral reimplantation. Although technically challenging, the described case demonstrates the feasibility and success of such an approach.

Circumferential mucosal incision around a lesion is effective for reliable endoscopic mucosal resection. However, mucosal incision with a needle knife is difficult, even with submucosal injection of normal saline solution. To make needle-knife incision easier and safer, sodium hyaluronate has been used rather than normal saline solution. The aim of this study was to evaluate the clinical outcome of endoscopic mucosal resection with circumferential mucosal incision assisted by submucosal injection of sodium hyaluronate.. For 70 gastric lesions treated by submucosal injection of sodium hyaluronate, the size of the lesion and the resection specimen, the en bloc resection rate, complications, and local recurrence during follow-up were assessed.. The mean size of the lesions and resection specimens were, respectively, 19.9 mm and 30.0 mm. The en bloc resection rates were 89% (42/47) for lesions up to 20 mm in diameter and 48% (11/23) for those greater than 20 mm (1-20 mm vs. >20 mm, p = 0.0004). Three patients underwent surgery because of invasive cancer in the EMR specimen. During follow-up (median 14 months, range 3-38 months), 2 recurrent lesions were found. No major complication occurred.. Submucosal injection of sodium hyaluronate is a reliable method with a high success rate for en bloc resection of lesions up to 20 mm in diameter. Mucosal incision with a needle knife can be performed safely with submucosal injection of sodium hyaluronate.

Because small flat colorectal neoplastic lesions (i.e., flat adenomas and flat adenocarcinomas) may be as translucent as the surrounding mucosa, they can remain undetected at conventional endoscopy. By combining high-resolution video endoscopy and chromoscopy, we detected 109 colorectal flat neoplastic lesions in 55 of 232 patients studied. Forty-three (78%) of the 55 patients with flat neoplastic lesions were over 60 years of age. No flat neoplastic lesions were seen in patients under 40 years of age. Flat neoplastic lesions were more frequent in men (35%) than in women (15%). Seventy-seven (71%) of the 109 flat neoplastic lesions measured 0.5 cm or less, 23 (21%) between 0.6 and 1.0 cm, and 9 (8%) more than 1.0 cm. Low-grade dysplasia and high-grade dysplasia were found in 94 (86%) and 13 (12%) of the flat neoplastic lesions, respectively. Adenocarcinoma was diagnosed in 3 (3%) flat lesions: 1 (1%) carcinoma originating in a flat adenoma and 2 (2%) adenocarcinomas without recognizable adenomatous elements. No adenocarcinomas were seen in lesions measuring 1.0 cm or less. Fourteen flat neoplastic lesions had a central depression at endoscopy. Flat neoplastic lesions with central depression more frequently showed high-grade dysplasia (43%) than did flat neoplastic lesions without central depression (7%). Central depression in flat neoplastic lesions should be considered a possible endoscopic marker for severe dysplasia. Our results suggest that flat neoplastic lesions occur more frequently than previously reported in Scandinavia. Flat adenomas may play an important role in the histogenesis of colorectal cancer.

From October 1987 to March 1991, 21 (8%) superficial early cancers were found among 256 early colorectal cancers (Dukes A and B1). Superficial early cancers were defined as early cancers less than 3 mm in height. These tumors were found scattered throughout the large intestine and were often observed as reddish spots, which were easily overlooked without careful observation. Histologically, 19 (90%) of them were well-differentiated adenocarcinomas, and five (24%) of them reached the submucosal layer. Eighteen (86%) of them were not associated with adenoma.

During the last 10 years, we have experienced 41 cases of minute cancer, which is equivalent to 13.9% of all resected early stomach cancers. Out of 44 lesions in 41 cases, 17 lesions were diagnosed preoperatively, while 27 were unexpectedly detected by serial sections of the resected stomach. Most lesions were located along the lesser curvature of the body and antrum. There was no nodal involvement or vessel permeation. Histologically differentiated adenocarcinomas were encountered in 86.4%, associated with intensive intestinal mucosa in many cases. We have stressed that dye endoscopy using indigo carmine and methylene blue is very useful for the diagnosis of minute cancer.

Forty patients with stomach cancer, including 25 patients with early carcinoma, were examined endoscopically during the perfusion of Indigo carmine dye into the celiac artery in association with vasomotors. In all of these patients the diagnosis had been established definitively by aimed biopsies before the procedure. This new endoscopic examination is useful not only to determine the margin of the superficial carcinoma, even when it is covered with regenerative epithelium, but also to detect small lesion less than 10 mm in diameter. Liver function tests in 31 patients who underwent the examination have negated the possibility of acute toxicity of the dye. But this new method should be employed with caution in hypertensive or high-risk patients.
