The diagnosis of leak tends to be earlier in LRYGB patients. Endoscopic therapies are more frequently required in the management of leaks following LSG, while in those following LRYGB, drainage alone leads to resolution of leak in the majority of cases.
In a carefully selected group of severely obese patients ≥ 70 years old, LSG may be safe, with acceptable postoperative complication rates, weight loss results, and improvement in comorbidities.
Albeit longer operating time, revision of LAGB to LRYGB is a safe procedure, with similar complication rates when compared to primary LRYGB. Although revisional LRYGB does result in less weight loss than primary LRYGB, the procedure's safety makes it a very plausible option as a rescue operation for failed LAGB.
The performance of one-stage revisional LRYGB after failed LAGB seems to be a safe procedure, with noninferior outcomes when compared to a two-stage revisional procedure. It is a valid option, except in cases of mechanical and infectious band complications.
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.
