Thirty eight patients underwent pancreatoduodenectomy for histologically confirmed adenocarcinoma of the head of the pancreas. Twenty one underwent a pylorus preserving pancreatoduodenectomy and seventeen the classical Whipple procedure. We undertook this retrospective analysis to compare longterm survival following the two different surgical procedures. Patients in the two groups were comparab...

Currently, the occurrence of diseases in digestive system swine has increased. Environmental stress and gastric bacteria were associated with body imbalance ulcer, which are related to pathological changes stomach. This study aimed investigate stomach histological characteristics beta-agonist free, hygienic, natural different farming methods. Three types swine’s stomachs bought from three farms...

Background: This study investigated the effects of pre-treatment with Moringa oleifera extract on the histomorphology and histomorphometry of the pylorus and duodenum of rats following ethanol-induced gastrointestinal injury. Methods: Following extract and ethanol treatment, pylorus and duodenum of the rats were processed for histological procedures, and tissue quantification of total antioxida...

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...

AIM Influence of chronic hyperglycemia on chemical coding of enteric neurons in stomach using pig as a model for human diabetic complications. METHODS Ten pigs were divided into two groups: diabetic (D group, n = 5) and control (C group, n = 5). Pigs constituting the experimental group were given streptozotocin (150 mg/kg). Animals were euthanized six weeks after the induction of diabetes. Th...
