Modified jejunoileal bypass surgery with biliary diversion for morbid obesity and changes in liver histology during follow-up.

Bariatric surgery is the most effective treatment for morbid obesity. The classic procedure, jejunoileal bypass, has many complications including rapid progress of liver disease. The senior author (I.F.) has developed a modification of jejunoileal bypass, which we believe overcomes many of the shortcomings of the classic procedure.
Consecutive patients referring for bariatric surgery were included. A modified jejunoileal bypass in which the defunctionalized limb is eliminated by anastomosing its ends to the gall bladder and cecum was performed. Liver biopsies were taken during operation and at a mean of 16 months later. The patients were followed for 5 years.
Forty-three patients were enrolled. The mean value of weight and body mass index (BMI) fell from 128 kg and 46 kg/m(2) before operation to 85 kg and 31 kg/m(2) at 5 years, respectively (p < 0.001). There was no significant change in the degree of liver steatosis and necroinflammation. The mean liver fibrosis score increased from 0.1 to 0.9 (p = 0.015). No sign of advanced liver disease was observed during the 5-year follow-up.
The modified jejunoileal bypass is very effective in inducing and maintaining weight loss for 5 years and does not lead to hepatic failure or rapid progression of liver disease.
