There are two phases of fore-stomach development during the first 200 days of pouch life in tammar wallaby. For the first 170 days, the mucosa displays an immature gastric glandular phenotype that changes to a cardia glandular phenotype, which remains for the rest of the animal's life. During this 200-day period after birth, the pouch young (PY) is dependent on maternal milk, which progressivel...

Background. Drain inclusion inside the gastric pouch is rare and can represent an important source of morbidity and mortality associated with laparocopic Roux-en-Y gastric bypass (LRYGBP). These leaks can become chronic and challenging. Surgical options are often unsuccessful. We present the endoscopic management of four patients with drain inclusion. Patients. All four obese morbidly patients ...

Gastric bypass is one of the most frequently performed surgical procedures in bariatric surgery. A neoplasm within the gastric pouch is a somewhat infrequent complication but with important survival consequences. We present the case of a 51-year-old woman who developed an adenocarcinoma in the bypassed stomach three years after bariatric surgery; the tumour was incidentally discovered after gyn...

BACKGROUND After Roux-en-Y gastric bypass (RYGB), a substantial number of patients do not achieve successful long-term weight loss. In cases of loss of restriction, the application of an adjustable gastric band ("salvage banding") over the gastric pouch, or gastrojejunostomy, could prevent weight regain or increase weight loss. The objective of this literature review is to provide an overview o...

The biochemical process by which cells of the stomach produce hydrochloric acid remains a mystery. Although the approximate concentration of the acid has been calculated on indirect evidence, the exact concentration as it is secreted has not been determined in any animal. This is despite the fact that, over a period of many years, increasingly precise observations have been made. The difficulty...

Objectives: To assess the outcomes of Single anastomosis Gastric Bypass in management Morbid Obesity.Materials and Methods: This study was conducted at Lady Reading Hospital, Peshawar between 1st June, 2017 28th February 2021 included 88 patients that underwent Mini-gastric Bypass/ One gastric bypass. Following DVT prophylaxis with subcutaneous enoxaparin, a 15-18 cm long pouch formed over boug...

To elucidate the role of microbiological factors in pouchitis, this study investigated the composition of ileal reservoir microflora, the mucus degrading capacity of bacterial enzymes as well as the pH and the proteolytic activity of pouch effluent. Stool samples were collected from five patients with pouchitis and nine patients without pouchitis. The flora of patients with pouchitis had an inc...

BACKGROUND Gastric diverticula are infrequent anatomic abnormalities that are usually asymptomatic. AIM We report a case of large gastric diverticulum and discuss diagnostic and therapeutic challenges. CASE REPORT A 63-year-old man was admitted with vague epigastric discomfort. Physical examination and laboratory investigations were normal. Endoscopy revealed an erosive gastropathy and a po...

While researching the mechanisms of gastric secretagogue action of mor phine, the effects of hexamethonium, atropine and secretin on morphine-induced gastric secretion were studied, and were compared with those on food-, histamine and tetrapeptide-induced gastric secretion in conscious dogs, and on histamine-, tetrapeptide and bethanecol-induced gastric secretion in anesthetized dogs. Effect of...

BACKGROUND Ever since the first total gastrectomy, there has always been a great concern in increasing the survival of patients, and with the advance of techniques, in improving the quality of life of these patients. The most common reconstruction technique of the gastrointestinal transit is the Roux-en-Y. The reposition of a functional pouch in place of the resected stomach was proposed to min...
