Reversal of jejunoileal bypass

The postoperative course of 48 morbidly obese patients upon whom a JIB operation was performed is reported. The indications for reversal of the JIB, the reversal operations and the gastric restrictive operations performed upon these patients are described. The results of this clinical investigation indicate that serious sequelae develop in most patients treated by JIB indicating reversal. A simultaneous gastric restrictive operation should be performed upon most of these patients to help them prevent excessive weight gain after reversal of JIB.
