A study looking at rational for reversal of failed bariatric operations concluded:
“The decision to reverse, rather than revise, a problematic bariatric operation is motivated by the perspective that the outcome of revision would also be problematic. Improved patient education and follow-up by the primary surgeon might have obviated the need for reversal in about one half of the patients in the present series.”
