Introduction:
Jejunoileal bypass (JIB) was an effective treatment for morbid obesity in the 1970s, but shortly after it fell out of favor due to horrific side effects, including liver failure, nephrolithiasis and drastic vitamin deficiencies. Although there are few living people with JIB, the management of these patients can be challenging.
Case presentation:
We describe a case of a 58-year-old female with a history of JIB 46 years prior who had an impending renal failure due to nephrolithiasis. She underwent a jejunostomy feeding tube prior to reversal. After reversal, our patient developed failure to thrive with functional obstruction of the newly incorporated small bowel. This bypassed bowel underwent a severe inflammatory transformation after the introduction of enteric feeds, suggesting an immunological type response to antigens in food. It wasn't until a long and debilitating 12 months and resection of this inflamed bowel that our patient was able to regain bowel function and gain weight.
Conclusion:
Jejunoileal bypass is an archaic procedure for morbid obesity. Due to its debilitating and at times lethal side effects, it has been replaced with newer techniques. Despite advances, there are still patients out there who have had a jejunoileal bypass. This case report and review of the literature details our experience with this procedure.
