The purpose of this study was to evaluate mini-gastric bypass (MGB) as a second bariatric procedure for patients with behavioral nutritional problems after primary restrictive procedures, with special emphasis on operative and postoperative outcomes.   Patients and methods: This was a prospective cohort study that was conducted in the Department of General Surgery at Ain Shams University Hospital from 2012 to 2014, where laparoscopic mini-gastric bypass (MGB) was performed in 30 consecutive patients with nutritional behavior problems after restrictive surgery. The outcome of surgery was assessed at 3,6,9 and 12 months for correction of nutritional behavior problems, as well as the body mass index (BMI). Nutritional deficiencies due to MGB were monitored.   Results: MGB was successful in prevention of vomiting and correction of solid food intolerance in 27 (90%) out of the 30 patients. The sweet eating behavior was corrected in all patients but new nutritional problems in the form of dumping and bilious vomiting were reported. Weight loss results were very satisfactory after one year.   Conclusion: MGB is a good successful second procedure in correction of nutritional problems arising after primary restrictive surgery. Both solid food intolerance and sweet eating were successfully corrected. There was also a very satisfactory improvement in weight loss results.
