Having bariatric surgery is a huge, life-changing decision, and we want you to feel both confident and informed. Here, you can learn about the procedures we offer in more detail.
Gastric sleeve surgery, sometimes also called partial gastrectomy, reduces the stomach to about 25% of its original size. A smaller stomach means reduced appetite and quicker satiety (sense of fullness), ensuring steady weight loss. Surgery is only performed on the stomach; the intestine is not touched.
The procedure involves removing two-thirds of the stomach along its length so instead of looking like a pouch, it looks like a long tube or shirt-sleeve. The smaller stomach tube remains attached to the intestines, thus ensuring a normal digestion process and proper nutrient absorption.
Gastric sleeve surgery can be performed as a stand-alone procedure or as the first stage in a gastric bypass procedure and generally has fewer potential complications than gastric bypass surgery.
Gastric bypass surgery promotes weight loss by dramatically decreasing the size of the stomach and thus allowing only small amounts of food to be eaten at one time. This procedure comprises two steps: partitioning of the stomach and reconstruction of the gastrointestinal tract.
First a small, thumb-sized pouch is created from the upper stomach using surgical staples. This process leaves the larger part of the stomach non-functional.
Second, the small intestine is divided into two parts. One end is then attached to the stomach pouch. The other end, which is still connected to the part of the stomach that is no longer functional, is reattached to the intestinal tract to enable drainage of the gastric juices.
With this procedure, food bypasses most of the stomach and part of the small intestine, thus reducing food intake and disrupting calorie absorption.
Mini Gastric Bypass
The gastric bypass omega loop, or mini-gastric bypass, is a simpler alternative to the Roux en-Y procedure with a lower risk of complications and greater chance of sustained weight loss.
The procedure consists of two steps: reduction of the stomach and looping of the small intestine to connect to the smaller stomach.
First, the left part of the stomach is detached along the entire length of the stomach, leaving a long narrow tube. Then a loop of the small intestine is brought up and attached to the stomach tube. This process bypasses the upper part of the intestine while still enabling drainage of gastric juices from the detached part of the stomach.
The gastric loop procedure has a similar effect to standard gastric bypass surgery but with about half as many complications.
Often when someone chooses to have bariatric surgery, and follows the after-surgery plan, they lose a significant amount of weight and they maintain this weight loss. However, in some instances, a weight loss procedure will not lead to as much weight loss as the surgeon and patient hope for. In addition, other issues such as abdominal hernia or gallbladder stones can occur. For this reason, a percentage of bariatric surgeries eventually requires revisional surgery.
In the instances where a revisional bariatric surgery procedure may be considered, it must be decided if the revisional surgery will work and what the risks of such a procedure will be. There are several factors that help make this decision:
When and where the initial operation was performed
The type of procedure the patient received
The surgeon’s level of experience at the time of surgery
The postoperative instructions given after the initial surgery
Weight loss history following the initial surgery
Complications history following the initial surgery
Types of revisional surgeries available:
- Band to Mini Bypass – removal of the band and performance of Mini Bypass surgery.
- Sleeve to Bypass – the abdomen is detached approximately 15 cm from the esophagus, binding the remnants of the abdomen and attaching it to the small intestine.
