Gastric bypass is indicated for the surgical treatment of severe obesity, a diagnosis which is made when the patient is seriously obese, has been unable to achieve satisfactory and sustained weight loss by dietary efforts and has comorbid conditions that are either life-threatening or serious impairment to the quality of life.
It has been found to produce a weight loss comparable to that of Roux-en-Y gastric bypass. [18] The risk of ulcers or narrowing of the gut due to intestinal strictures is less so with sleeve gastrectomy versus Roux-en-Y gastric bypass, but it is not as effective at treating GERD or type 2 diabetes. [18]
Many complications that followed jejunoileal bypass operations were caused by bacterial overgrowth in the excluded blind loop. The arthritis-dermatitis syndrome was one of the common distressing disorders. The pathogenetic mechanism was thought to be an immune-complex-mediated process related to bypass enteritis.

Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine , bypassing the lower stomach, the duodenum , and the first portion of the jejunum .
When enough full-thickness bites have been taken for a suture row, a cinch is passed through the scope over the suture. Typically, sutures are placed starting at the border of the antrum and gastric body at the incisura, then placed proximally up to the border of the gastric body and fundus. Each row of sutures can be a straight line or one of ...
Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
Gastrectomy, gastric bypass surgery, diabetes, esophageal surgery, absent or inefficient pyloric sphincter, pyloric stenosis Dumping syndrome occurs when food, especially sugar, moves too quickly from the stomach to the duodenum —the first part of the small intestine—in the upper gastrointestinal (GI) tract .
About half of cases are due to peptic ulcer disease (gastric or duodenal ulcers). [3] Esophageal inflammation and erosive disease are the next most common causes. [3] In those with liver cirrhosis, 50–60% of bleeding is due to esophageal varices. [3] Approximately half of those with peptic ulcers have an H. pylori infection. [3]
