The primary end-point of our study was to evaluate the results after Roux-en-Y gastric bypass (RYGB) performed as primary treatment for morbid obesity and revisional surgery (RS) after laparoscopic sleeve gastrectomy (LSG). The secondary endpoint was to assess the influence of the time elapsed between both surgeries in the development of complications after RS.An observational, single-centre study was carried out on a cohort of 54 patients who underwent RYGB from 2012 to 2021. 29 (53.7%) patients undergone primary RYGB and 25 (46.3%) undergone revisional RYGB.According to our results, RYGB performed as RS associates higher conversion to laparotomy as well as postoperative complications and hospital readmissions when compared to primary RYGB. In addition, revisional RYGB showed worse results in terms of weight loss and mayor comorbidities control. Time elapsed between LSG and revisional RYGB showed no impact on the development of adverse events.Therefore, RS must be addressed with caution even in experienced groups since the complexity of the procedure which entails more risk of complications and lower weight loss.
The objective of the study was to compare the results after laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in the treatment of morbid obesity in terms of weight loss, comorbidities remission and complications.An observational unicentric study of 154 obese patients who underwent bariatric surgery from 2012 to 2021 was designed. We report the results of 125 LSG patients and 29 patients with LRYGB.The effectiveness of LSG and LRYGB as primary treatment for morbid obesity was comparable, without statistical significance related to weight loss.Regarding comorbidities resolution, LRYGB showed better results. Although both techniques associated low morbidity rate, the LRYGB presented with higher intraoperative and postoperative complications rate and longer hospital stay. On the other hand, LSG required a higher percentage of reinterventions and showed worse results related to preoperative reflux disease remission and de novo reflux onset.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
