Jejunocolic bypass

Last revised by Dr Yuranga Weerakkody on 05 Jul 2015

Jejunocolic bypass was an early form of bariatric surgery. It is no longer performed due to severe side effects.

For this bypass, the proximal small bowel (jejunum) is transected and anastomosed to the colon (such as the transverse colon). The other end of the small bowel is closed and the distal small bowel is left blind-ending in the abdomen.

The bypass was designed to treat obesity by malabsorption of ingested food. The procedure was eventually abandoned because of severe side effects including diarrhea, steatorrhea, vitamin malabsorption, dehydration, and electrolyte imbalance, as well as many other side effects.
