Malabsorptive (Medial) Gastric Bypass
Stomach-restrictive surgery with significant Malabsorption
Gastric Bypass also called medial roux-en-y gastric bypass is a stomach-restrictive procedure. It involves creating a small stomach pouch and a bypass of roughly two-thirds to three-fourths of the small intestine length resulting in substantial decrease in calorie absorption. Weight loss is achieved by means of restricted food quantity coupled with reduced absorption of calories.
How It Works
Under this procedure, a small stomach pouch (approximately the size of an egg) is created by stapling off a section of the stomach. This restricts the quantity of food that can be consumed and gives a feeling of satisfaction on eating much smaller quantity of solid food. The procedure further involves dividing the small intestines length wise. The lower section is attached directly to the small stomach pouch. The food consumed by patient is passes through this portion of the small intestines undigested till it meets the. The top portion of intestines produces the digestive juices (bile and pancreatic juices) and is called the bilio-pancreatic limb(BPL). This is where the food mixes with intestinal juices and food absorption occurs. Absorption of nutrients and calories depends on the length of this portion. Shortening of this portion reduces the possibility of weight regain by decreasing the calorie absorption.
- As weight loss is achieved by a bifold technique, weight loss is easy, quick, predictable and long lasting. Upto 80% of excess weight can be lost and maintained over life time.
- Major co-morbidities like diabetes, sleep apnea, hypertension, high cholesterol and depression are either resolved or show substantial improvement.
- A comparatively low-maintenance surgery, does not require very close follow ups and monitoring or frequent readjustments
- No risk of “dumping” syndrome triggering nausea, cramping, diarrhea, sweat, vomits and palpitations. This syndrome generally follows when a patient consumes carbs or sugar or eats too quickly.
When is the Laparoscopic Bypass most recommended
Laparoscopic Bypass procedure is recommended for patients who are:\
- Morbidly obese and have chronic co-morbidities like diabetes, cardiovascular or metabolic disorders etc.
- Ailing from hiatus hernia and acute acid reflux beside obesity
- Keen to lose 60-80% of excess body weight and maintain it for long
