Bariatric surgery in Singapore
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
A laparoscopic adjustable gastric band also referred to as a lap band, is an inflatable silicone device placed around the top segment of the stomach to restrict the patient's eating capacity. Thereby treating obesity by reducing excess body fat. Gastric banding is a less invasive surgery of its kind. Gastric banding is performed on the patient using laparoscopic surgery. This results in a shorter hospital stay, faster recovery, smaller incision and scars. Also less discomfort and pain as compared to open surgical procedures. Because no part of the stomach is stapled or removed, and the patient's intestines are not re-routed. Therefore the patient can continue to absorb nutrients from food normally without any obstructions
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.
