Laparoscopic Roux En Y Gastric Bypass
This is the longest standing or “Gold standard” Bariatric surgical procedure where the outcomes of other bariatric surgical procedures are often compared with. In this operation a 20-30 cc gastric pouch is created just below the Gastro-Oesophageal junction which essentially functions as a small stomach. Thereafter the proximal small bowel (jejunum) is divided at about 150-200cm from Duodenum and is being brought up and connected to the gastric pouch to form the “food” limb. The remaining end of the proximal jejunum is connected to this further down as a bilio-Pancreatic limb to complete the operation.
Whilst providing restriction to food intake this operation effectively bypasses about 1/3rd of the effective nutrient absorbing area of small bowel causing “mal-absorption” leading to rapid weight reduction and control of illnesses associated with obesity. Anastamotic leaks and weight gain after a time period can occur with this procedure. Internal hernia related to small bowel with weight loss is also a known complication of this surgery.
