Weight Loss Surgery Options

The three most frequently performed weight loss operations are the Roux-en-Y gastric bypass, the sleeve gastrectomy and the adjustable gastric band. Together, these three operations account for over 90% of weight loss operations performed worldwide. At Aspiring Bariatrics Laparoscopy and Endoscopy Limited we offer all three operations using modern laparoscopic (keyhole) surgery techniques for faster recovery and less scarring.

Laparoscopic Roux-en-Y Gastric Bypass

The ‘gastric bypass’ is the most common weight loss operation performed worldwide.  It has been performed since the 1960’s as an open operation, and laparoscopically since 1993.

In this operation the stomach is partitioned in to a small stomach pouch approximately 30mLs (two tablespoons) in size.  The small intestine is joined directly to this pouch and rejoined to itself in a ‘Y’ shape approximately 1m further down.  This results in people feeling much less hungry, and feeling satisfied after eating a very small portion of food.  On average, people will lose 30-40% of their starting body weight in 12-18 months (e.g. someone weighing 150kg may lose 45-60kg).  Gastric bypass may also have a specific anti-diabetes effect due to bypassing the upper small intestine.

Laparoscopic Sleeve Gastrectomy

The ‘gastric sleeve’ is a relatively new weight loss operation that has been performed since 2000.  It involves removing 4/5ths of the stomach to turn it from a reservoir for food in to a narrow tube or sleeve.  Weight loss outcomes between 3- and 5- years after sleeve gastrectomy are similar to those after a gastric bypass.  On average, people will lose 25-35% of their starting body weight in 12-18 months (e.g. someone weighing 150kg may lose 37-53kg).  Due to the shorter history of sleeve gastrectomy, less is known about the long term durability of this operation.

Laparoscopic Adjustable Gastric Banding

Laparoscopic Adjustable Gastric Banding has been performed since 1990.  It involves placing an adjustable silicone band around the upper stomach to slow the entry of food.  Regular post-operative band adjustments are necessary for this procedure to be effective.  Laparoscopic Adjustable Gastric Banding has the lowest early complication rate of any bariatric operation.  However concerns about the necessity for further surgeries to correct complications, and more variable weight loss outcomes have led to a recent deline in the popularity of this operation.

ORBERA® Gastric Balloon

The ORBERA® Gastric balloon is a temporary endoscopic treatment to assist people in feeling less hungry while losing weight through diet and exercise.  The balloon is placed in the stomach via the mouth during an endoscopic, day stay procedure and removed six months later in a similar manner.  It is combined with a 12 month comprehensive diet and exercise program.  On average, people with an endoscopic balloon lose over three times more weight during this time than diet and exercise alone.  It is indicated for people with a body mass index of between 27 and 40 kg/m².
