Types of Bariatric Surgery

All types of bariatric surgeries are done under general anesthesia. These are minimally invasive surgeries which require a short stay in hospital, recovery after surgery is faster and resumption of routine activities is also possible earlier. Since such procedures are as the name implies, minimally invasive (key hole), there is usually less loss of blood and damage to tissues, hospital stay is shorter (about 3-4 days) and no post-operative ICU stay or bed rest.

Gastric banding

A soft band is placed at the upper part of the stomach, which reduces the amount of food consumed at one time and provides a feeling of fullness for a longer time. Hence there is weight loss

Laparoscopic sleeve gastrectomy

About two-thirds of the stomach is removed laparoscopically and this makes the stomach look like a tube. The part of the stomach that produces Ghrelin hormone (which stimulates appetite and promotes fat deposition in body) is removed

Gastric bypass

Size of the stomach is reduced and a part of small intestine is bypassed so that digestion process is altered and less food is consumed and absorbed

Mini Gastric Bypass Procedure

The Mini-Gastric Bypass (MGB) is a type of obesity surgery which is a simple, successful and inexpensive technique in weight loss surgery. It is a hybrid procedure that has the advantages of a restrictive procedure (like Laparoscopic sleeve gastrectomy) and also the advantages of a malabsorptive procedure ( like Roux-en-y gastric bypass).It involves creating a long narrow tube of stomach along its right border and then joining it to a loop of small intestine about 180 cms from the starting point of the jejunum. The MGB is a viable and effective alternative to the Roux en-Y procedure due to the simple jejunal loop creation, thus reducing the morbidity and malasborption seen with a proper gastric bypass. MGB is fast becoming popular because of low risk of complications and good sustained weight loss. It has the effectiveness of sleeve and Roux-en-y gastric bypass without their complications or reflux problem.

In the MGB restriction of stomach volume is achieved by surgically altering the stomach to make its size and capacity smaller as in sleeve gastrectomy. Next mal-absorption is accomplished by looping and attaching the small intestine to the stomach tube bypassing about 150 to 180 cm of intestine as in Roux-en-Y gastric bypass

Advantages

  • Single stage permanent procedure
  • No resection or removal of parts stomach or intestine
  • No implants like a balloon or band
  • No reflux or acidity problem
  • Hunger is reduced
  • Sustained long term weight loss
  • Easily reversible and revisable if necessary
  • No prolonged hospital stay
  • No major mal-absorption complications

Hospital stay

  • Is usually 2-3 days
  • Patient should be able to take enough fluids and nutrients by mouth before discharge
  • Lack of physical activity.
