a 33-year-old female presented with intermittent abdominal pain and severe attacks of lower gastrointestinal (gi) bleeding since 2 weeks. she has had history of irregular menses in last 3 months. in the labeled rbc-scan study, the bleeding site was detected in left upper quadrant (luq). in surgery, a tumor with the diameter of 2ã—1cm in a 65 cm distance of ligament of trietz was detected. in pa...
Primary malignant schwannoma of the small intestine is an extremely rare disease. We report a primary malignant intestinal schwannoma of the small bowel in a 66-year-old woman, who was admitted to the hospital because of fatigue and anaemia. On clinical examination there was a solid mass at the abdomen. Ultrasound scanning showed an abdominal tumour. Computed tomography showed a mass in the are...
Obscure gastrointestinal bleeding is an important dilemma. Brunner's gland hamartoma is an extremely rare tumor generally localized in the duodenal bulb. We present a 34-year-old woman who had suffered from several episodes of melena for the past three years. Endoscopic examinations were normal. Computed tomography showed a large target lesion over the right abdomen and an image representing in...
Variations in the morphology of pancreas are not very common. We observed a rare variant of the uncinate process of the pancreas that extended in the mesentery of the small intestine. After its origin from the lower part of the head of the pancreas, the mesenteric process (MP) passed over the third part of the duodenum to enter the mesentery of the jejunum and ileum and extended up to the level...
This study was conducted to explore whether exposure to bisphenol A (BPA) during pregnancy could change intestinal digestion and absorption function in offspring using pigs as a model, and whether methyl donor (MET) could counteract the BPA-induced impacts. Fifty Landrace × Yorkshire sows were divided into four dietary groups throughout gestation: control diet (CON); control diet supplemented w...
BACKGROUND Stromal tumors of the jejunum (GIST) and omentum (EGIST) are uncommon and dearth of information still exists on their occurrence concurrently. CASE DETAILS Here, we report a nine year old girl that presented with tender abdominal mass measuring 14 × 8 cm associated with features of gastric outlet obstruction and hyponatremia of 115mmol/L. A diagnosis of hyponatremia in a child with...
The effect of jejunal bypass on pancreatic growth and plasma cholecystokinin (CCK) was investigated in rats. Rats underwent bypass of jejunum or sham operation. Rats with jejunal bypass were further divided into three groups; one group received a continuous infusion of a partially hydrolysed liquid diet (Vital) into the bypassed jejunum; a second group received the nutrient solution mixed with ...
Current evidence suggests that there are three sphincters that regulate the flow of chyme from stomach to the duodenum. We investigated the hypothesis whether a fourth 'physiologic sphincter' exists at the duodeno-jejunal junction. The pressure response of the jejunum, duodeno-jejunal junction and duodenum to individual balloon distension of the jejunum and duodenum was recorded in 28 healthy s...
1. To establish the speed on onset of jejunal and ileal mucosal hypoplasia and hypofunction in parenterally fed rats, we measured three indices of mucosal mass, three mucosal enzymes and quantitative histology after 3, 6, 10 and 15 days of total parenteral nutrition and compared the results with those in two orally fed control groups, one with and one without intravenous catheters and metabolic...
