Duodenal Switch/ Biliopancreatic Diversion with Duodenal Switch

 

The duodenal switch also known as Biliopancreatic diversion with duodenal switch is a type of weight loss surgery which works on the principle of Restriction and malabsorption.

 

The surgeon enters the abdominal cavity laparoscopically by making 4-5 tiny incisions through which instruments are entered. A small pouch is created from the stomach which remains attached to the duodenum (first segment of the dmall intestine). The remaining portion of the stomach is removed from the body. The duodenum is then attached to the lowest segment of the small intestine thus bypassing the major second and third segments of the small intestine. This is known as the duodenal switch.

 

The small pouch of the stomach created is merely 30% of the original size of the stomach thus restricting the food intake. The duodenal switch bypasses the major segments of the small intestine this resulting in far less absorption of calories from the food consumed which results in successful weight loss.

 

Benefits:

  • Patient loses approximately 70-80% of excess body weight.
  • Since the pylorus (sphincter at the end of the stomach which releases food into the small intestine) is preserved, Dumping syndrome is prevented.
  • Short hospital stay and quick recovery
  • Obesity related comorbidities like Type 2 Diabetes are also found to be resolved to a great extent

 

Risks associated:

  • The patient needs to be on regular multivitamin and other nutritional supplements to avoid nutritional deficiencies
  • The stomach portion that is removed is an irreversible procedure
  • Staple line leak
