Bariatric surgery is a kind of weight loss procedure where surgery is done on the stomach or intestines to help people lose weight by altering the normal digestive process.
Common Types of Bariatric Surgery:
Adjustable Gastric Band
Adjustable gastric banding is a kind of restrictive weight loss surgery (bariatrics) designed for obesity patients. The synthetic band is adjusted via a small access port placed just below the skin
Gastric Bypass Surgery is a form of bariatric surgery or weight-loss surgery in which a portion of the stomach is stapled off and rendered unusable. The intestine is then reattached to the smaller portion of the stomach. With the newly reduced capacity of the stomach, patients of gastric bypass surgery cannot eat as much food as they did before because they feel “full” much quicker than before.
Roux-en-Y Gastric Bypass
Roux-en-Y gastric bypass surgery, or simply gastric bypass surgery, is a procedure almost exclusively used in surgical weight-loss applications to correct obesity. This gastric bypass procedure involves stomach stapling to reduce the stomach to a pouch of volume 30-60 mL. The gastric bypass procedure connects this pouch at a point midway along the small intestine.
Vertical Banded Gastroplasty
Vertical Banded Gastroplasty (VBG), also known as Stomach stapling, has been a common restrictive operation for weight control. Both a band and staples are used to create a small stomach pouch. In the bottom of the pouch is an approximately 1cm hole through which the pouch contents can flow onto the remaining portion of the gastrointestinal tract.
Stomach stapling is a restrictive technique for managing obesity. The pouch limits the amount of food a patient can consume at a givem time and slows passage of the food. Stomach stapling is effective when clubbed with a malabsorptive technique, in which part of the digestive tract is bypassed reducing the absorption of calories and nutrients. Combined restrictive and malabsorptive technique are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most prevelant. In this technique, staples are used to form a pouch that is connected to the small intestine, bypassing the lower stomach, the duodenum, and the first portion of the jejunum.
This kind of weight loss surgery is losing popularity as more surgeons begin using the Adjustable gastric band. The newer adjustable band does not require incision into the stomach and does not use any staple lines, thus making it a much safer alternative.
In just a few years Thailand has emerged as one of the leading medical tourism destination for people from US , UK or middle east. Obesity surgery in Malaysia has been around since mid 1990s. These are the weight loss procedures performed in Malaysia:
- Laparoscopic Adjustable Gastric Banding
- Laparoscopic Rouxen Gastric Bypass Surgery
- Sleeve Gastrectomy
- Duodenal Switch
Technical advancement across the world has reflected in Malaysia hospitals as well with the arrival of modern laparoscopic equipments, Bariatric instrumentation and other infrastructure used in bariatric surgery.
The procedures also have advanced with changing times. For instance, any patient wishing to undergo weight loss surgery is usually administered a preoperative evaluation that includes modern techniques like psychology evaluation, GI x-ray, blood test for bacteria in the stomach, blood counts, blood urea, liver function tests etc. Only after the preliminary evaluation are the nutrition charts and surgery dates confirmed.
