A 70-year-old patient presented with a 6-month history of bloating, flatulence, diarrhea and foul-smelling retching. He had undergone a Billroth II gastrectomy due to complicated peptic ulcer disease 30 years ago. Physical examination denoted mild abdominal distention. Laboratory tests revealed macrocytic anemia (Hb: 10.1 g/dL, MCV: 102 Fl) with severe vitamin B12 deficiency (161 pg/mL), althou...

he incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. It occurs mostly in patients in the 6th decade of their life. Of all the small bowel diverticuli, jejunal diverticulum is the most common type. This rare entity is usually asymptomatic. However, they may cause chronic non-specific symptoms for a long period of time ...

BACKGROUND & AIMS Patterning of the small intestinal epithelium along its cephalocaudal axis establishes three functionally distinct regions: duodenum, jejunum, and ileum. Efficient nutrient assimilation and growth depend on the proper spatial patterning of specialized digestive and absorptive functions performed by duodenal, jejunal, and ileal enterocytes. When enterocyte function is disrupted...

Recent studies suggest that the jejunal/kidney-type facilitative glucose transporter (GLUT5) functions as a high-affinity D-fructose transporter. However, its precise role in the small intestine is not clear. In an attempt to identify the fructose transporter in the small intestine, we measured fructose uptake in Xenopus oocytes expressing jejunal mRNA from five species (rat, mouse, rabbit, ham...

Colonoscopy is rarely associated with complications such as colonic perforation. Perforation of the small bowel is extremely rare, especially if the procedure is done without therapeutic interventions. Several factors are associated with this entity. Perforation of the ileum has been reported, but proximal jejunal perforation secondary to rupture of jejunal diverticulum during colonoscopy has n...

Metastatic renal cell carcinoma (MRCC) is a rare cause of massive lower gastrointestinal bleeding (LGIB). We report a 51-year man who underwent left nephrectomy for renal cell carcinoma (RCC) 6 years ago. presenting with massive LGIB. Preoperative abdominal computed tomography (CT) revealed small bowel mass. Exploration of the abdomen revealed jejunal mass. Resection of the mass along with the ...

We are reporting a case of a 22 year-old female patient, who underwent a pancreaticoduodenectomy previously for a solid-pseudopapillary neoplasm of the pancreas and was re-admitted seven years later with a pancreatic leak following disruption of the pancreatico-jejunal anastomosis. Exploratory laparotomy revealed a large collection at the level of the pancreatic anastomosis with major disruptio...

Effects of jejunal infusion of a saline solution, a protein meal, and a mixed protein and carbohydrate meal on biliopancreatic secretions were compared in six healthy volunteers. Protein infusion stimulated biliopancreatic secretions whereas carbohydrate infusion inhibited these secretions compared with saline infusion. The roles of lipid, carbohydrate, and caloric load on the inhibition of pan...

INTRODUCTION Isolated ectopic varices located in the small bowel are uncommon. Portal hypertension caused by liver cirrhosis is the most common predisposing risk factor. PRESENTATION OF CASE We present an unusual case of massive gastrointestinal bleeding from idiopathic jejunal varices in a 73-year-old Caucasian male without portal hypertension. Exploratory laparotomy disclosed ectopic varice...
