The development of splenosis is a known consequence of splenic rupture. A case is presented of acute appendicitis in a patient with a past history of abdominal trauma who required laparotomy for unknown reasons. During appendicectomy a mass was found in the mesoappendix which proved to be evidence of splenosis.

To investigate the current incidence and identify the current etiologies of rapid gastric emptying (dumping syndrome) in patients with a spectrum of gastrointestinal symptoms, including nausea, vomiting, abdominal pain, or diarrhea.. The results for a 4-h radionuclide gastric emptying test (GET) using a standardized scintigraphic technique were reviewed in 545 patients to see which patients met criteria for rapid gastric emptying, defined as >50% emptying of isotope-labeled solid meal at 1 h.. Forty-eight of 545 (8.8%) patients (28 females, mean age 46 +/- 2 years, range 32-58 years) had rapid GET. Seventeen of 59 (35%) met Rome III diagnostic criteria for cyclic vomiting syndrome (CVS). Twelve of these 59 (25%) patients were regarded as non-ulcer dyspepsia and six (13%) had dyspepsia in the setting of diabetes mellitus. Five (10.5%) were post-fundoplication surgery, where an accidental vagotomy was confirmed by sham meal challenge; previous gastric bypass surgery for obesity had been performed in three (6%) patients. Five (10.5%) patients with unexplained abdominal pain and diarrhea had the working diagnosis of irritable bowel syndrome.. Rapid gastric emptying can be identified in a sizeable subset (9%) of patients with unexplained nausea, vomiting, abdominal pain, and diarrhea when criteria are applied to the standardized scintigraphic gastric emptying meal.

The aims of this study were to determine the electrogastrographic patterns in children with functional dyspepsia and to investigate the correlations among electrogastrogram (EGG), gastric emptying (GE), and pain severity.. We studied 30 children (19 F; mean age 11.4 years) with functional dyspepsia. Electrogastrography was performed for 30 minutes fasting and for 1 hour during a GE test after ingestion of an isotope-labeled solid meal. The percent emptying was measured every 10 minutes for 1 hour after the meal. The dominant frequency of the EGG, the change in the postprandial peak power (deltaP), and percent dysrhythmia during each recording session were calculated. Specific symptoms were graded from 0 (none) to 4 (severe) by the patient.. Of 30 patients, 14 (47%) had slow GE, and 15 (50%) had abnormal EGG (dysrhythmia > or = 30% or deltaP < 0). GE was slow in 73% of patients with an abnormal EGG but was slow in only 20% of patients with normal EGG (P = 0.009). GE was negatively correlated with fasting bradygastria (r = -0.383, P = 0.04). Abdominal pain was the most severe dyspeptic symptom, both during fasting and after the meal. Patients with an abnormal EGG had an increased mean pain severity score (3.5 +/- 0.2 vs. 2.5 +/- 0.2, P = 0.002).. Sixty percent of functional dyspepsia subjects had either slow GE or abnormal EGG. Patients with abnormal EGG were more likely to have slow GE. EGG abnormalities were associated with more severe postprandial pain and should be considered a possible mechanism for dyspeptic symptoms.

A case of pericholecystic hyperperfusion on Tc-99m sulfur colloid (SC) flow images with a pericholecystic rim of increased activity (PCHA) on delayed planar and single-photon emission computed tomography images of the liver was seen in a patient with a history of multiple renal transplants admitted with cramping right lower quadrant abdominal pain. Laparotomy performed 5 days after the scan revealed an acutely perforated gangrenous gallbladder and occluded cystic duct. The secondary findings of gallbladder hyperperfusion and PCHA or "rim sign" have been frequently reported with Tc-99m IDA hepatobiliary imaging. These secondary findings in conjunction with a nonvisualized gallbladder on an IDA scan suggest a complicated or advanced stage of acute cholecystitis and usually require urgent surgical intervention. The rim sign on Tc-99m SC scintigraphy also likely indicates the same grave diagnosis.

Our aim was to determine whether domperidone could improve the symptoms of patients with gastroparesis, accelerate gastric emptying, and enhance quality of life.. Seventeen patients (13 women, 4 men; mean age 42.9 yr) with documented gastroparesis were evaluated. A baseline gastric emptying study was performed using an isotope-labeled solid meal and a follow-up study was repeated > or =6 months after initiating domperidone therapy. The severity of nausea, vomiting, abdominal pain, and bloating were obtained at baseline and at 6-month intervals and were graded from 0 to 5 (0 = none, 5 = most severe). Also, the number of hospital admissions were noted during the study period. Patients were asked to assess their overall health status and quality of life and were begun on domperidone 20 mg q.i.d. On average, patients received domperidone for 23.3 months (range 6-48 months). Domperidone doses ranged from 40 to 120 mg daily during the study period.. Gastroparesis symptom scores were reduced from 4.1 +/- 0.22 (mean +/- SEM) to 1.3 +/- 0.2, and hospital admissions were decreased significantly during the study compared with before domperidone therapy (p < 0.05). At baseline, patients had a 87.3 +/- 3.71% retention of a solid meal at 2 hours compared with a 57.2 +/- 5.04% retention during domperidone therapy (p < 0.05). Domperidone treatment enhanced the quality of life in 88% of patients. The mean prolactin level was 58.9 pg/ml during the study and three patients reported gynecomastia.. Chronic domperidone treatment in patients with gastroparesis significantly reduced GI symptoms and hospitalizations, enhanced quality of life, and accelerated gastric emptying of a solid meal to a normal rate. Domperidone successfully treats gastroparesis on a long-term outcome basis and has an excellent safety profile.

This is a case report of a patient with an initial diagnosis of chronic pancreatitis who actually had metastatic carcinoid tumor. His symptoms of abdominal pain, weight loss, and diarrhea were manifestations of the large tumor bulk within the liver as well as carcinoid syndrome. Although abdominal CT scans showed multiple liver lesions, the primary lesion was not identified by conventional imaging studies. However, the mid-gut primary lesion was visualized on in-111 labeled octreotide scintigraphy; where the liver lesions were better delineated and seen to be separate from the normal pancreas when the Tc-99m sulfur colloid images were compared to the octreotide images.
