Brief Summary:
The goal of this prospective, multi-center, post-market study is to measure AEON™ Endostapler performance with the EASY/THICK MODE feature for laparoscopic bariatric surgery against the Echelon Flex™ Powered Stapler system from Ethicon. Stapler performance will be evaluated primarily by incidence and degree of staple line bleeding through a third-party blinded primary outcome evaluator. The study will include 60 total consecutive cases of individuals undergoing a planned laparoscopic sleeve gastrectomy (LSG). The LSG procedure will be performed according to institutional standard-of-care and all subjects will undergo standard preoperative evaluation as well as post-operative care. Relevant data will be collected using the Data Collection sheet which should be filled out following each procedure by a member of the surgical or nursing team.
