Revisional bariatric surgery--safe and effective.
BACKGROUND
Revision operations have traditionally been considered difficult and associated with a high complication and long-term failure rate. This paper demonstrates that revision and/or conversions to Roux-en-Y gastric bypass are generally safe as well as effective in long-term weight maintenance and control of co-morbidities.


METHODS
A retrospective study from January 1989 through August 1999 was done involving 141 patients who had had various gastroplasty (118), gastric banding (6), jejunoileal bypass (3), or loop (2) and Roux-en-Y gastric bypass (RYGBP) procedures (12), with either technical failures or poor long-term maintained weight loss.


RESULTS
The demographics were: mean pre-operative weight at original surgery 264 lbs (120 kg); postop weight at a mean elapsed time since surgery of 5 years, 4 months: 188 lbs (85 kg), or a mean excess weight loss of 59%. The mean BMI dropped from a pre-op 45 to a post-op 31. There were 7 complications which required emergency surgery (5%), which included 4 leaks, 2 subphrenic abscesses, and 1 wound dehiscence. Other complications included 4 hernias, 3 staple-line failures, 1 transient renal failure, and 3 incidences of peptic ulcer disease requiring surgery, giving a total major complication rate of 13% in 17 patients, with no deaths. An earlier experience of this author comparing conversion RYGBP vs revision gastroplasty found better morbidity rates and weight loss with those converted to RYGBP.


CONCLUSIONS
Converting failed gastric limiting and other bariatric procedures to RYGBP was safe and effective. Technical approaches to each problem type encountered are presented.
