Common complications such as internal gastrointestinal hemorrhage (bleeding) and staple line leakage occur in both surgeries. [46] Late complication: For the anastomotic stricture, [47] there is a 2.9%-23% chance for patients to experience gastrojejunal anastomosis. [46] This complication more often occurs in the laparoscopic era
Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed. The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis.
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 .
Lastly, this procedure is post-operatively associated with decreased bone density and higher incidence of bone fractures. This may be due to the importance of gastric acid in calcium absorption. [4] Post-operatively, up to 70% of patients undergoing total gastrectomy develop complications such as dumping syndrome and reflux esophagitis. [5]
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.
A 2016 Cochrane review found low-quality evidence of no difference in short-term mortality between laparoscopic and open gastrectomy (removal of stomach), and that benefits or harms of laparoscopic gastrectomy cannot be ruled out. [84] Post-operatively, up to 70% of people undergoing total gastrectomy develop complications such as dumping ...
Similarly, the chances of developing complications after surgery depend on the reason for the surgery and the type of complication in question. For example, antrectomy for peptic ulcers has a 1-5% chance for the condition to recur, a 12% chance of developing diarrhea , and a 30-35% chance of developing Dumping syndromes .
It is important to note that, in order to maintain their weight reduction, patients must carefully follow post-operative guidelines relating to diet, exercise, and band maintenance. Weight regain is possible with any weight loss procedure, including the more radical procedures that initially result in rapid weight loss.
