According to Romy et al,1 RYGBP is a “better” bariatric procedure than GB. I personally agree with them. However, before we make from this conclusion a paradigm, a few caveats remain.
First, case-control studies can suffer from bias when one treatment is sensed as better than the other ab initio.2 Since prospective randomized studies comparing the 2 procedures are hardly realizable, better evidence could be obtained by prospectively comparing matched patients submitted to either procedure in 2 different centers with recognized expertise in GB or RYGBP.
