Biliointestinal bypass

International Journal of Obesity

|January 1, 1981

Summary

This summary is machine-generated.

Bilio-intestinal bypass, a modification of jejunoileal bypass, effectively reduces weight and improves side effects in morbidly obese patients. This surgical technique demonstrates promising results with minimal serious complications.

Background:

Conventional jejunoileal bypass (JIB) has limitations including a "blind loop" and disruption of enterohepatic circulation.
These limitations can lead to significant side effects, necessitating alternative surgical approaches.

Purpose of the Study:

To introduce and evaluate the efficacy of bilio-intestinal bypass (BIB) as a modification of JIB.
To assess BIB's ability to mitigate JIB's side effects by maintaining enterohepatic circulation and connecting a jejunal loop to the gallbladder.

Main Methods:

BIB was performed on 22 patients as a primary procedure and on 4 patients as a secondary procedure for JIB complications.
Patient weight, side effects, and anastomosis patency were monitored.

Follow-up included intravenous cholangiography and Tc99 HIDA scintigraphy.

Main Results:

A mean weight reduction of 50 kg was observed over 24 months in 20 patients.
Overweight percentage decreased from 89% to 14% in a 5-year follow-up subgroup.
Anastomoses were patent in 90% of evaluated patients, with no gallstones detected.
Renal calculi occurred in 3 patients, but urine oxalate levels remained normal.

Conclusions:

Jejunoileal bypass combined with cholecystojejunostomy (BIB) is a safe and effective method for selected morbidly obese patients.
BIB successfully reduces body weight and ameliorates side effects associated with traditional JIB.
