Laparoscopic mini gastric bypass is a type of weight-loss/bariatric surgery. As the name suggests it can be performed through key-hole method (laparoscopy). In this technique 4 to 5 tiny cuts of half to one cm are made on the abdomen and the whole surgery is performed through these. In a Laparoscopic mini gastric bypass, a long narrow stomach pouch is created using surgical staplers. A 150 to 200 cm loop of small intestine is then taken and attached to the stomach pouch in a loop fashion. The food comes into the stomach pouch and flows directly into the distal small intestine. It bypasses the remaining stomach and the first part of small intestine.
Following are the criteria for eligibility-
Laparoscopic mini gastric bypass surgery is a restrictive and mal-absorptive procedure and can lead to an excess weight loss of about 75 to 85% on an average. This occurs over a period of 12 to 18 months. Various factors affect weight loss after bariatric surgery. It is important to recognize that obesity is a chronic progressive disease and needs life long support. Diet and lifestyle modification are mandatory after bariatric surgery to get good results and for weight maintenance.
Laparoscopic mini gastric bypass is as safe as any other surgery like gall bladder surgery or a knee replacement surgery. The overall risk of complications is less than 1%. Many complications like leak from staple lines, deep vein thrombosis and to the extent of death are listed on the web. It is important to visit a bariatric surgeon in Mumbai and understand the pros and cons and not just rely on hearsay and information on google. Regular follow up along with diet and behaviour modification is the key to long term success after bariatric surgery. There should be no weakness after the initial few weeks of surgery. If you continue to feel weak then you must get in touch with the bariatric team for further evaluation.
Due to the nature of the loop anastomosis in an MGB, there is a risk of bile reflux into the gastric pouch. In the long term there is a hypothetical risk of developing cancer but till date cancer has been reported in less than 0.1% of patients. A yearly upper GI endoscopy is recommended after any kind of bariatric surgery to check if any untoward changes are happening.
