Proximal Jejuno-Ileal Bypass as Revision of Roux-en-Y Gastric Bypass.

Introduction: Bariatric surgery is established as a possibility for the treatment of obesity, allowing weight reduction and remission of obesity comorbidities. Reported suboptimal clinical response rates are as high as 30-60% (insufficient weight loss or gain, defined as BMI greater than 35 kg/m or excess weight loss less than 50%). Proximal jejuno-ileal bypass (PJIBP) is a promising option when re-intervention is required.
