The purpose of this observational registry is to evaluate the safety and the clinical efficacy of laparoscopic bariatric surgery using stapling devices (easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical). The goal of the study will be achieved by reporting peri- and postoperative complications and the clinical outcome after surgery in a prospectively maintained database.
Obese patients eligible for laparoscopic bariatric surgery. This registry will collect data from 250 laparoscopic bariatric procedures in which anastomoses are created with the easyEndoTM Universal Linear Cutting Stapler and reloads (Ezisurg Medical).
Exclusion Criteria:
Device: easyEndoTM Universal Linear Cutting Stapler and reloads (Ezisurg Medical)
Investigational device: easyEndoTM Universal Linear Cutting Stapler and reloads (Ezisurg Medical). Device for the creation of anastomoses during laparoscopic bariatric surgery manufactured by Ezisurg Medical.
