Surgical revision of loop (“mini”) gastric bypass procedure: multicenter review of complications and conversions to Roux-en-Y gastric bypass

The results of this preliminary review have confirmed that MGB does require revision in some patients and that conversion to RYGB is a common form of revision. A national registry to record the complications and number of revisions is proposed to gain insight into the need for revision after MGB and other nontraditional bariatric procedures.
