Gastric Bypass

gastric bypassLaparoscopic Gastric Bypass

A laparoscopic Gastric bypass is an operation to create a new stomach pouch and bypass. This means that food does not need to go through the stomach.  It is achieved by grafting (attaching) a piece of intestine onto the pouch so that food passes through the pouch and down the bypass.

It is performed for helping very overweight patients achieve substantial and permanent weight loss.  This is because it restricts both the amount that someone can eat and reduces appetite.

The operation is carried out laparoscopically, which is also known as keyhole surgery.  This means that the surgeon makes five small incisions (cuts) in the abdomen (belly) to get to the stomach.  The surgeon may decide to convert to an open procedure (the traditional way of carrying out operations through a longer incision) if they think it would be safer.

What does the operation involve?

The operation takes approximately two hours. For some patients, the surgery can be technically difficult depending on body-build or previous surgery. In these circumstances the operation can take longer. Before the operation you’ll come into hospital on the day of surgery and will wear anti-embolism socks (like very tight stockings) to prevent blood clots forming in your legs. The anaesthetist will see you before or on the morning of surgery.
