BACKGROUND Partial pancreatico-duodenectomy (PD) is the standard treatment for tumors of the pancreatic head. Today, preservation of the pylorus has been widely accepted as the surgical standard in this procedure. A common postoperative complication is the occurrence of delayed gastric emptying (DGE), which causes impairment of oral intake andpatients' quality of life, prolongation of hospital ...

Antiulcer effects of pantoprazole, a proton-pump inhibitor, on water-immersion restraint stress (WIRS)-, alcohol (ethanol)- and pylorus ligation-induced gastric ulcers were investigated in male rats. Rats were orally administered with pantoprazole 30 min prior to exposure to various types of ulcer inducers. In stress-induced ulcer model, rats were subjected to WIRS at 22℃ for 4 hours, and the d...

BACKGROUND AND OBJECTIVES The vertical sleeve gastrectomy is a common bariatric procedure. The operation is relatively standard, but there are still variations among surgeons. The two main variations are bougie size and extent of distal resection. Some surgeons will start the gastric resection at 2 cm proximal to the pylorus, whereas others start at 6 cm. Our hypothesis is that there are anatom...

I. The rate of flow of digesta along the intestinal tract, and particularly the changes occurring in proteins during their passage through the intestine were determined in six rams; each animal was fistulated with three cannulas which involved six different sites of the intestine. CrzO, was used as a marker substance to measure the rate of flow of the digesta. 2. In the sections of the intestin...

BACKGROUND Indomethacin, a non-steriodalanti-inflammatory drug, is used mainly for the treatment of painful joints such as rehumatoid arthritis, osteo-arhtritis, gout, ankylosing spondylitis etc. It relieves pain, reduces swelling and tenderness of the joints. It also induces ulceration of stomach and small intestine both in experimental animals and humans. MATERIAL AND METHODS In this study ...

The relation between pyloric motor activity, opening, and closure was examined in eight healthy men. Manometry was performed with an assembly combining 13 side holes and a sleeve sensor positioned astride the pylorus. Simultaneous with manometry, pyloric opening and closure and antroduodenal contractions were observed fluoroscopically with the antrum filled with barium. During intraduodenal nor...

The objective of the present study was to investigate the antiulcer activity of methanol extract of Oxalis corniculata (whole plant) using pylorus ligation and indomethacin-induced gastric ulceration in Wistar rats. The extract was preliminary evaluated for acute oral toxicity test using Organisation for Economic Co-operation and Development guidelines 423. Further, it was studied for antiulcer...

CASE 1 A 27-year-old man had epigastric pain, relieved by antacids, occurring two hours after meals, for three years. A clinical diagnosis of peptic ulcer was made. At laparotomy a hard white thickening of the pylorus was found. Partial gastrectomy with closure of the duodenal stump and anastomosis of the stomach and jejunum was performed. Naked-eye examination revealed a localized thickening u...

Double pylorus and gastroduodenal fistula are rare conditions and can be either congenital or acquired. We report a case of a 58-year-old man with epigastric pain and dyspepsia in which the upper gastrointestinal endoscopy revealed an acquired double pylorus, probably caused by a gastric ulcer.
