sodium-morrhuate and Esophageal-and-Gastric-Varices

We report two cases of squamous cell carcinoma of the esophagus following endoscopic injection sclerotherapy for esophageal varices. The interval between sclerotherapy and the development of carcinoma was 24 months in case 1 and 21 months in case 2. The sclerosant was 5% sodium morrhuate in case 1 (total dose, 10 ml) and 5% ethanolamine oleate in case 2 (45.5 ml). Although no recurrent variceal bleeding occurred after sclerotherapy, we could not perform any curative surgical treatment for esophageal cancer because of the advanced stage of the cancer and the severity of the accompanying liver dysfunction. It is difficult to determine the relationship between sclerotherapy and carcinoma; however, long-term surveillance is essential to avoid overlooking a neoplasm in the esophagus after endoscopic injection sclerotherapy.

Sclerotherapy is currently used to treat acute variceal bleeds and also in the long-term management after a variceal bleed. The technical variants and results of sclerotherapy in both settings are reviewed and compared with alternative surgical treatment options. Sclerotherapy has become an accepted therapy for acute variceal bleeding. In Cape Town it is used in combination with the Sengstaken tube. A preliminary analysis of an ongoing trial comparing a rigid scope technique with a fibreoptic scope technique provides support for the use of the rigid scope in acute variceal bleeding. The place of repeated sclerotherapy in long-term management has become controversial. Varices can be eradicated and repeated variceal bleeds markedly reduced, but its role in improving survival requires further clarification.

The current standard treatment of bleeding esophageal varices is band ligation. Although endoscopic sclerotherapy has largely been supplanted by band ligation, there are still clinical situations in which injection methods are useful. Endoscopic ultrasound (EUS) may allow for a more complete evaluation of esophageal varices and perforating veins and may allow for more effective delivery of sclerosant. Our aim was to evaluate the use of color Doppler EUS-guided sclerotherapy for the obliteration of esophageal varices.. Five patients with esophageal varices (Child's A = 1, B = 2, C = 2) underwent dynamic EUS-guided sclerotherapy with color flow Doppler. EUS sclerotherapy was performed using Varijet (2.5 mm catheter) injector needles and sodium morrhuate directed at the perforating vessels until flow was completely impeded (2 to 4 mL per injection site). Data collected included (1) sessions to obliteration, (2) episodes of recurrent bleeding, (3) complications, and (4) mortality.. Patients undergoing EUS-sclerotherapy required 2.2 sessions to achieve obliteration of varices. No patient had a recurrence of bleeding and no deaths occurred. One patient developed an esophageal stricture that responded to balloon dilation.. Dynamic EUS-guided sclerotherapy with color flow Doppler may be safely and effectively used for the treatment of esophageal varices. It allows for effective delivery of sclerosant with favorable outcomes. Prospective, multicenter, randomized trials are warranted.

From November 1985 to February 1991, sixty patients were randomized to three groups of intravariceal sclerotherapy: (1) many punctures of low quantity sclerosant, (2) one puncture of large quantity sclerosant, and (3) one puncture of large quantity sclerosant with transendoscopic balloon. The early effects and complications were investigated. Varices eradication was reached 91.2% in group 1, significantly higher than group 2 (58.3%) (P < 0.05), similar to group 3(89.9%). However, balloon group (group 3) required shorter duration than group 1 (12.6 vs. 21.7 days) (P < 0.05). There were no significant differences in complications, but all 6 esophageal stenosis were in group 1, recurrent bleeding was 11.4% in group 1.35.7% in group 2 and 0 in group 3 during sclerotherapy sessions. Further more, we found though attempted to inject into variceal veins, accurate intravariceal injection reached only 46.8% in accordance with venographic findings. We conclude that sclerotherapy with transendoscopic balloon seems to be more simple, safer, and required short time to produce successful variceal sclerosis.

Thirteen Child's class C patients with variceal hemorrhage requiring 6 or more units of blood were randomly assigned to groups receiving either flexible endoscopic sclerotherapy using 5% sodium morrhuate or esophageal transection/reanastomosis employing the EEA Auto Suture stapling instrument. One patient with a previous hiatus hernia repair was assigned to the transection group and had a mesocaval shunt. The randomization groups compared favorably with each other and with a retrospective shunt group (20 patients). Although transection patients required significantly less operative time and fewer blood transfusions, the outcome of the transection group was significantly worse than that of the shunt group. The trend in survival likewise favored the shunt group rather than the sclerotherapy group. Although the reported operative mortality rates of transection and sclerotherapy are less than that of portal decompression, the results of this study--the first controlled trial of these procedures--would warrant distinct caution in using either of these new techniques in high-risk patients. Portal decompression may still be the procedure of choice in class C patients with substantial variceal hemorrhage.

Esophageal and gastric varices are associated with significant morbidity and mortality for cirrhotic patients. The current modalities available for treating bleeding esophageal and gastric varices, namely endoscopic band ligation and sclerotherapy, require frequent sessions to obtain effective thrombosis and are associated with significant adverse effects. A more effective therapy that results in long-term vascular occlusion has the potential to improve patient outcomes. In this study, we investigated a new potential method for inducing long-term vascular occlusion by targeting segments of a rabbit's auricular vein in vivo with low-duty-cycle, high-peak-rarefaction pressure (9 MPa), pulsed high-intensity focused ultrasound in the presence of intravenously administered ultrasound microbubbles followed by local injection of fibrinogen and a pro-inflammatory agent (ethanol, cyanoacrylate or morrhuate sodium). The novel method introduced in this study resulted in acute and long-term complete vascular occlusions when injecting a pro-inflammatory agent with fibrinogen. Future investigation and translational studies are needed to assess its clinical applicability.

The safety and efficacy of poly-N-acetyl glucosamine (p-GlcNAc) gels were compared with standard agents in three different dog studies to assess abdominal venous collaterals, bleeding esophageal varices, and bleeding gastric varices.. Adult dogs with prehepatic portal hypertension and large abdominal venous collaterals, esophageal varices, or gastric varices were studied.. Significantly higher sclerosis rates were seen with F2 or F4 p-GlcNAc gels and standard sclerosants. F2 and F4 gels had high rates of permanent hemostasis, low rates of secondary ulceration, and significant reductions in esophageal and gastric variceal size. These results were either equivalent to or significantly better than the most commonly used gastric varix hemostatic agent (glue) or other sclerosing agents.. F2 and F4 poly-N-acetyl glucosamine gels are promising therapeutic agents for venous and variceal hemostasis.

Endoscopic injection sclerotherapy and endoscopic variceal ligation have been found to have shortcomings in the treatment of esophageal varices. In this study the effectiveness of photodynamic therapy (PDT) in the obliteration of veins was investigated to evaluate its potential in the treatment of esophageal varices.. Auricular margin veins of rabbits were irradiated by copper vapor laser after intravenous injection of 10 mg/kg of hematoporphyrin monomethyl ether (which is a hematoporphyrin derivative) into the rabbits. Control groups included rabbits that received irradiation only, that received injection of photosensitizer only, and that received injection sclerotherapy (using sodium morrhuate). The treated areas were observed macroscopically and also identified using with ultrasonic miniprobe. Biopsies were performed and the specimens were examined microscopically after hematoxylin-eosin staining and Victoria blue staining. In addition, two patients with newly visible veins within the esophageal wall after endoscopic injection sclerotherapy underwent PDT. Intravenous injection of 5 mg/kg of hematoporphyrin monomethyl ether was given, and the newly visible veins were endoscopically irradiated by copper vapor laser. Endoscopic re-examination was performed 1 month later to evaluate the therapeutic effect.. Thrombi of the auricular margin vein were formed and blood flow was obstructed after PDT. Thrombus formation and diffused necrosis of adjacent tissue was found after injection of sodium morrhuate. On ultrasonic examination, the lumina of the veins showed a slightly higher echo after PDT compared with a lower echo before treatment, which was another sign of thrombus formation. The rabbit ears showed a diffused low echo after injection of sodium morrhuate, indicating diffuse necrosis. On microscopic observation, destruction of the endothelium and formation of thrombus was seen after PDT. Further observation of specimens stained with Victoria blue showed that the layer of elastic fiber was intact. After injection of sodium morrhuate, extensive necrosis of tissue was seen microscopically. No macroscopic, ultrasonic, or microscopic change was found in the rabbits that received irradiation only or injection of photosensitizer only. The rate of thrombus formation in rabbits that received PDT was significantly higher than that in the rabbits that received irradiation only or injection of photosensitizor only ( P = 0.015, P = 0.015), and comparable to that in the rabbits that received sclerotherapy ( P = 0.467). In the clinical study, at endoscopy 1 month after PDT both the number and the "red sign" of newly visible veins were found to have decreased. No adverse effect was found.. PDT can destroy the endothelium of the vein, result in thrombus formation, and eventually obliterate the vein. It is potentially a new method for the treatment of esophageal varices.

Seventy-three patients with bleeding esophageal varices were treated by transesophageal injection of sclerosing agent through fiberoptic gastroscope (EIS). Hemostasis was noted in 63 cases (86.3%). The success rate was 100% among those classified as Child A & B and 79.59% in Child C patients. Hemostasis was achieved after repeated EIS in 90.2% of the patients. Bleeding stopped in 82.14% of the patients who failed to respond to balloon tamponade and in 95.65% of the patients with recurrent bleeding after open surgery. The recurrence rate of bleeding esophageal varices after EIS was 13.7% and the mortality rate was 15.07%. EIS was generally performed in the first week of hemorrhage, thereafter, it was repeated at a 4-14 days interval. EIS was a simple and safe procedure with a high percentage of immediate hemostasis and a comparatively low mortality. It could be used to tide some poor risk patients over the crisis for possibly further surgery.

Twenty-seven manometric and 22 18-hour pH monitoring studies were done in 17 consecutive patients undergoing esophageal endosclerosis. Prior to endosclerosis, esophageal manometry was normal in eight of nine patients. Peristaltic dysfunction was observed in all 13 postendosclerosis patients and consisted of (1) decreased mean peristaltic amplitude pressures. Pressures were 61.4 and 74.7 mmHg at 0 to 2 cm and 3 to 4 cm above the lower esophageal sphincter (LES), respectively, prior to treatment. After endosclerosis, values fell to 30.2 and 43.3 mmHg; (2) a drop in mean resting LES pressure from 22.3 mmHg before endosclerosis to 17.1 mmHg afterward and (3) an increase in the rate of peristaltic propagation failure from 12% to 26% after endosclerosis. Esophageal pH monitoring demonstrated gastroesophageal reflux (GER) in three of seven patients before endosclerosis and in five of 11 patients afterward. Because of the major incidence of GER before endosclerosis, the procedure could not be causally incriminated. However, GER was roughly correlated with the severity of the manometric dysfunction. There was no correlation of GER or manometric abnormality with the number of endosclerosis treatment nor the interval between endosclerosis and pH and manometric studies. The remote sequelae of the abnormalities are conjectural.

We describe the case of a 45-yr-old white male with portal hypertension and presumed Laennec's cirrhosis who developed squamous cell carcinoma of the esophagus 8 months after completion of a course of endoscopic variceal sclerotherapy. The epidemiology and natural history of esophageal cancer and their relationship to our patient are analyzed. This report emphasizes that squamous cell carcinoma of the esophagus should be considered in the differential diagnosis of postsclerotherapy dysphagia. Further studies will be required to determine whether or not esophageal variceal sclerotherapy is associated coincidently or causally with the development of squamous cell carcinoma of the esophagus in patients at increased risk for this condition.

Intravariceal injection of a sodium morrhuate sclerosant solution, an effective therapy for bleeding esophageal varices, is complicated occasionally by fever and pneumonia. To determine if embolization of sclerosant to or through the pulmonary circulation occurs, chest scintigrams were performed following intravariceal injection of 1-3 mCi 99m-Tc-MAA mixed with 5-20cc of sclerosant in 18 patients undergoing a total of 25 sclerotherapy sessions. Sclerosant embolization was documented in 15/25 procedures (60%). Tracer localization in esophageal veins cephalad to the injection site (gastroesophageal junction) occurred in 2 studies. Atelactasis, effusion, or infiltrate on chest x-ray occurred after 6/25 procedures. Post-sclerosis fever (greater than 99.5 degrees F) occurred in 5/15 (33%) with embolization and in 1/10 (10%) without. However, neither x-ray abnormalities nor fever were positively correlated with sclerosant embolization. We conclude that embolization of sclerosant to the pulmonary arterial circulation occurs frequently. Chest radiographs may be negative despite significant embolization.

Ten years after right hepatic lobectomy for primary hepatocellular cancer, a 45-yr-old black woman presented with bleeding esophageal varices. After five endoscopic injection sclerotherapy procedures using sodium morrhuate, she developed fever and elevated white blood count. Reendoscopy, chest x-ray, and upper gastrointestinal contrast x-rays showed no local complication. Urine analysis was normal, but CT scans, renal sonograms, and white blood cell radionuclide scan demonstrated bilateral perinephric abscesses. Percutaneous abscess drainage grew Streptococcus pneumoniae, normally found in the nasopharyngeal flora, which was probably a result of hematogenous spread. The perinephric abscesses were successfully treated with percutaneous drainage and antibiotics. Renal infection should be considered as a possible locus of distant blood-borne infection in patients who develop fever after endoscopic injection sclerotherapy.

Ulceration at the site of injection is a common sequel of endoscopic sclerotherapy. Most postsclerotherapy ulcers heal spontaneously, usually within 3 weeks. We report a patient who developed a large esophageal ulcer after sclerotherapy, which did not heal despite 2 years of aggressive medical therapy. He bled twice from the ulcer. This is the first report in which such an ulcer has been followed sequentially for 2 years and has remained unhealed.

We determined quantitatively the amount of sodium morrhuate that reaches the pulmonary vascular bed during endoscopic variceal sclerotherapy to ascertain whether this affects the diffusing capacity of the lung to carbon monoxide (DLCO). Eleven patients had measurements of DLCO and specific diffusing capacity (DLCO/VA) before and after sclerotherapy. In ten of these patients sclerotherapy was done using sodium morrhuate mixed with 99mTc-labeled albumin microspheres followed by quantitative radionuclide scanning. Most of the sodium morrhuate, 80 +/- 18% (SD) of the total dose, remained in the region of the esophagus. Only 20% of the injected dose reached the pulmonary circulation. There were no changes in DLCO or DLCO/VA. We conclude that most of the sclerosing solution injected during endoscopic variceal sclerotherapy remains at the site of injection. As a result, the pulmonary endothelium is exposed to small amounts of sodium morrhuate and no change in diffusing capacity occurs.

Adult respiratory distress syndrome has been reported after endoscopic variceal sclerotherapy with sodium morrhuate. It has been proposed that sclerosant entering the pulmonary circulation during intravariceal injections may cause pulmonary hypertension and capillary injury. The purpose of this study was to determine whether variceal sclerotherapy with sodium morrhuate causes capillary injury or pulmonary edema in humans. We studied the effect of sclerotherapy on gas exchange and pulmonary and systemic hemodynamics in 8 patients who required endoscopic variceal sclerotherapy for treatment of variceal hemorrhage. The pulmonary vascular resistance index increased from 246 +/- 67 dyn X s X cm-5/m2 (mean +/- SEM) at baseline to a high of 303 +/- 85 dyn X s X cm-5/m2 60 min after sclerotherapy (normal range 250-500 dyn X s X cm-5/m2). Pulmonary artery pressure remained stable while cardiac index decreased by 12% over the same period. There were also small increases in systemic vascular resistance index and systemic arterial pressure after sclerotherapy. Although there was no change in arterial oxygen tension, the alveolar-arterial oxygen difference improved after sclerotherapy. These results indicate that variceal sclerotherapy with sodium morrhuate is associated with clinically insignificant changes in pulmonary and systemic hemodynamics. We did not detect evidence of acute lung injury after sclerotherapy.

The authors evaluated whether depth of needle insertion as determined by needle length is an important factor in sclerotherapy-associated bacteremia. In 18 consecutive sclerotherapy sessions in which sodium morrhuate was used, blood cultures were positive in 11% when using an injector with only 3 to 4 mm of needle protruding beyond the sheath, compared with the 39% incidence of bacteremia previously observed when an injector was used which permitted 6 to 8 mm of needle to protrude (0.01 less than p less than 0.05). Twenty-five additional sclerotherapy sessions in which the shorter needle was used were performed with a different sclerosant, 1% sodium tetradecyl sulfate; only 8% of blood cultures were positive. No correlation was found between fever and bacteremia. The authors conclude that the exposed needle length of the injector must be specified in any report of endoscopic variceal sclerotherapy with the flexible endoscope since this length is critical in the incidence of associated bacteremia and possibly other complications.

Utilizing an equal mixture of 5% sodium morrhuate and 60% renografin, we studied four patients during a total of nine sessions of injection sclerotherapy of esophageal varices to determine radiographically the fate of injected sclerosant. Despite attempted intravariceal injections, 44% resulted in local and presumably paravariceal accumulation of contrast material within the esophageal wall. During 42% of injections, contrast material was rapidly cleared in a cephalad direction and proximal balloon compression of the esophagus did not prevent cephalad flow of sclerosant. In 14% the injected material was rapidly cleared in a caudal direction toward the gastric veins. This technique may be useful in future evaluations of the efficacy of various methods of injection sclerotherapy of esophageal varices.

Sclerotherapy for esophageal varices has recently gained wide acceptance in major medical centers for the control of bleeding esophageal varices. We have described two elderly patients with preexisting cardiac disease (right bundle branch block) in whom persistent bradyarrhythmia followed sclerotherapy using 5% sodium morrhuate. Both patients required insertion of a permanent pacemaker. This is the first report associating sclerotherapy with significant bradyarrhythmias.

Two of 30 patients with esophageal varices had respiratory distress develop within 8-24 h of esophageal sclerotherapy. Evidence of aspiration and sepsis were absent in these two patients with the clinical picture of adult respiratory distress syndrome. To investigate the possible etiologic role of sodium morrhuate in this syndrome, a sheep model was established and pulmonary hemodynamics, lung lymph flow, and albumin concentration were measured before and after the intravenous injection of 2.5-15.0 cm3 of sodium morrhuate. In all 8 animals studied, mean pulmonary artery pressures increased from 11.6 +/- 2.8 to 32.8 +/- 4.9 mmHg (p less than 0.01) 30 s after injection. These pressures returned to baseline values over 120 min. Lymph flow increased from 0.91 +/- 0.89 to 2.8 +/- 1.5 ml/30 min at 90 min postinjection (p less than 0.05) and returned to baseline values in animals monitored for 6-8 h. The lymph/plasma albumin ratio decreased from 0.856 +/- 0.08 to 0.74 +/- 0.01 (p less than 0.05) 120 min postinjection. Pulmonary edema was not evident histologically or gravimetrically (wet/dry weight ratio was 3.65 +/- 0.3 and not different from normal). It was concluded that sodium morrhuate injection in sheep causes marked but transient pulmonary hypertension associated with an increased lymph flow of relatively protein-poor lymph. Sodium morrhuate esophageal sclerotherapy may affect pulmonary hemodynamics and contribute to respiratory difficulties in patients.

Three patients with portal hypertension and variceal hemorrhage were treated with flexible fiberoptic esophageal vein sclerosis by injection of sodium morrhuate. Each of these patients bled after sclerotherapy, and deep esophageal ulcers were found at the previous injection sites. Postsclerotherapy pathologic features are presented in 2 patients. It is suggested that the sclerotherapy caused esophageal ulceration and bleeding. Careful evaluation of the sclerosing technique and its histopathologic consequences is needed.

During the past 3 2/3 yr, 6 children with portal vein thrombosis were treated for esophageal hemorrhage by direct injection of esophageal varices with sodium morrhuate (endosclerosis). Four children were actively hemorrhaging at the time of initial endosclerosis; 2 patients were treated electively. Endosclerosis was performed by (1) employment of an especially slotted rigid esophagoscope, (2) direct intravariceal injection, (3) injection of varices at the gastroesophageal junction only. In patients actively hemorrhaging, endosclerosis was repeated every 3 to 4 days until the bleeding ceased. Once bleeding was controlled the procedure was done at 6-wk intervals until esophageal varices were obliterated. In the four patients actively hemorrhaging, bleeding was controlled by 2 to 3 separate injection sessions. Four patients have completed treatment and varices are absent radiographically and endoscopically. No patient has rebled during or after treatment in follow-up from 1/6 to 3 2/3 yr. Esophageal endosclerosis is advocated as a legitimate alternative to portosystemic shunt operations and nonoperative management of esophageal variceal hemorrhage in children with portal vein thrombosis.
