Comment on: Banded versus nonbanded sleeve gastrectomy: 5-year results of a matched-pair analysis

I read with interest the manuscript entitled “Banded versus nonbanded sleeve gastrectomy: 5-year results of a matched-pair analysis” from a reputed university hospital in Germany [1]. The obvious weakness of this paper is that it is retrospective and nonrandomized. We have seen this problem in banded Roux-en-Y gastric bypass (RYGB), where enthusiastic results were first put into print in retrospective series, to realize that in randomized studies there was not much difference. Is that story going to repeat itself? A recent systematic review and meta-analysis of studies looking at banded versus nonbanded gastric bypass for morbid obes ity found no difference at 1 and 2 years on any variables studied.
