Laparoscopic Roux en-y 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 Roux en-y gastric bypass, a small 30 to 50 cc stomach pouch is created using surgical staplers. Small intestine is divided at about 50 to 100 cm from the duodeno-jejunal junction and attached to the stomach pouch in a “y” shaped fashion. The food comes into the stomach pouch and flows directly into the small intestine. It bypasses the remaining stomach and the first part of small intestine.
Laparoscopic Roux en-y gastric bypass leads to an excess weight loss of about 70 to 80% in 12 to 18 months. Patients also experience significant improvement in associated diseases like type 2 diabetes, high blood pressure, dyslipidemia, gout, PCOD, obstructive sleep apnoea, joint pains, liver disease etc. It also reduces the risk of venous thrombo-embolism and heart disease in the long term. Laparoscopic Roux en-y gastric bypass leads to a significant improvement in the quality of life of the patient.
In the long term the main issues observed with a laparoscopic Roux en-y gastric bypass are internal herniation, marginal ulcers, nutritional deficiencies and weight regain. However, obesity is a chronic progressive disease and as with any weight loss procedure, regular follow up with the bariatric surgeon team is the key to success after a laparoscopic sleeve gastrectomy. It is extremely important to follow a healthy lifestyle and a good exercise regime after a Laparoscopic Roux en-y gastric bypass surgery.
