Complications and Risks of Biliopancreatic Diversion Surgery
Judging the complications and risks of stomach bypass treatment of obesity involves an assessment of operative, perioperative, post-operative and long term complications. Also, the risks of gastric bypass must be weighed against the known health risks of severe obesity.
Bypass Complications and Health Risks
After all malabsorption surgeries, like biliopancreatic diversion, there is a period of intestinal adaptation during which bowel movements can be liquid and frequent. This bowel complaint, frequently accompanied by bloating, gas and foul smelling stools may reduce with time, but occasionally is a permanent condition.
Malabsorptive operations like biliopancreatic diversion bypass, pose a particular risk for nutritional deficiency. Nearly 30 percent of patients who have stomach bypass surgery develop nutritional deficiencies because they do not adhere to their post-operative guidelines concerning the need for nutritional supplements. This risk of malnutrition stems from the fact that gastric bypasses cause food to bypass the duodenum and jejunum - the places where important minerals like iron and calcium are absorbed into the bloodstream.
Due to the above, bariatric bypass patients have a high risk of chronic anemia or conditions like osteoporosis and metabolic bone disease. This is why biliopancreatic bypass surgery patients need to take vitamin and mineral nutritional supplements.
Risk of Dumping Syndrome
Biliopancreatic diversion bypass operations may also cause post-operative dumping syndrome. This occurs when the food in the stomach moves too rapidly through the small intestine. Symptoms of dumping include: nausea, sweating, feeling faint, and diarrhea after eating. The risk of dumping syndrome is lower after biliopancreatic diversion with duodenal switch as this procedure maintains the pyloric valve intact.
