With great interest we read the study of Gadiot and colleagues regarding the long-term results of laparoscopic sleeve gastrectomy (LSG) in the January 2017 edition of Obesity Surgery . First, we would like to express our appreciation of this very nice report portraying long-term data on a sizeable cohort of patients with LSG. Second, we would like to ask a few questions concerning the study.
In Table 3, the authors report on the failure rates at respectively 5 to 8 years postoperatively. Regarding inadequate weight loss following bariatric surgery, it is favourable to divide between weight loss failure (WLF)—inability to achieve 50% excess weight loss—and weight regain (WR)—significant weight gain after initial weight loss success. Is it possible to provide us with the WLF and WR percentages?
Furthermore, could the authors elaborate on the mentioned percentage of subsequent revision to laparoscopic Roux-en-Y gastric bypass (LRYGB), specifically whether these patients managed to return to adequate weight loss after revision?
Last, did the results in this study have specific implications on your patient selection nowadays, with regard to eligibility for either LSG or LRYGB?
