BACKGROUND After Roux-en-Y gastric bypass to avoid rapid gastric emptying, dumping syndrome and regained weight due to possible dilation of the gastric pouch, was proposed to place a ring around the gastric pouch. AIM To compare weight loss, consumption of macronutrients and the frequency of vomiting among patients who underwent Roux-en-Y gastric bypass with and without the placement of a con...

BACKGROUND A recently published prospective series has demonstrated that weight loss ceases 18 to 24 months following Laparoscopic Roux-en-Y gastric bypass (RYGB) and that, by 48 months, there is significant weight regain in 50% of patients. METHODS We report the case of a 38-year-old male patient who developed significant weight regain 42 months following laparoscopic (RYGB) and underwent la...

AIM To determine the contributions of gastrointestinal transit and pouch characteristics to bowel frequency in patients with an ileoanal reservoir and no pouchitis. METHODS Twenty one patients who had undergone restorative proctocolectomy, with ileostomy closure at least eight months previously, and who had no history of pouchitis were recruited. They were prospectively classified on the basi...

A 59-year-old man, with a history of Roux-en-Y gastric bypass 9 years previously, presented with chronic epigastric pain thought to be due to recurrent marginal ulceration. On diagnostic endoscopy he was found to have a 3-cm gastric pouch and a 18-mm gastrojejunal anastomotic diameter. Additionally, a 1-cm cratered ulceration on the jejunal aspect of the post-bypass anastomosis and a 3-mm fistu...

BACKGROUND: The cottage cheese test was developed in an attempt to find a simple way to measure functional pouch volume and to better understand the fate of the tiny proximal pouch following the gastric bypass procedure. METHODS: Our patients were asked to eat cottage cheese in a structured fashion before their return visits from 3 months to 2 years postoperatively. RESULTS: We found there was ...

BACKGROUND Gastric bypass (GBP) is the most common operation performed in the United States for morbid obesity. However, weight loss is poor in 10% to 15% of patients. We sought to determine the independent factors associated with poor weight loss after GBP. DESIGN Prospective cohort study. We examined demographic, operative, and follow-up data by means of multivariate analysis. Variables inv...

It is held as axiomatic that an understanding of the mechanism of the passage of substances from the blood stream to the gastric lumen must include a knowledge of the passage of these same substances in the reverse direction. In the previous paper (1), the absorption of radioactive sodium (Na24) from the stomach was reported. Tangible amounts of Na24 placed in a stomach pouch were found after 1...

Bariatric surgery (weight loss surgery) includes a variety of procedures performed on people who are obese. Weight loss is achieved by reducing the size of the stomach with a gastric band or through removal of a portion of the stomach (sleeve gastrectomy or biliopancreatic diversion with duodenal switch) or by resecting and re-routing the small intestines to a small stomach pouch (gastric bypas...

BACKGROUND Even though many types of reconstruction after total gastrectomy have been proposed to reduce postgastrectomy syndromes, choosing a method that would further improve the quality of life and nutrition of the gastrectomized patient is controversial. Hunt-Lawrence single pouch reconstruction seems to obtain better results compared with the more common Roux-en-Y technique, but both of th...

The inhibitory effect of fat in the upper small intestine was studied in dogs prepared with a Heidenhain pouch, gastric fistula, and jejunal fistula. Gastric secretion was stimulated by a constant intravenous infusion of pentagastrin, and emulsified olive oil was introduced into the jejunum. The small intestine of the dog was denervated by complete transection of the mesentery except for the su...
