A Registry of Laparoscopic Bariatric Surgery Using Stapling Devices: Observation of Safety and Clinical Efficacy (STAP-JOLI)

A Multicentric Prospective Registry of Laparoscopic Bariatric Surgery Using Stapling Devices: Observation of Safety and Clinical Efficacy

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.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Device performance	Number of procedures with technical success	At index procedure
Device performance	Scoring of: easy of intra-abdominal device positioning, grasping/climbing force, sharpness of the blades, staple-line formation, device stability, device maneuverability, device consistency and reliability, ergonomic design, hemostasis. Each of the aforementioned items receives a score from 0 to 4, with 0 indicating that the user is very unsatisfied and 4 indicating that the user is very satisfied.	At index procedure
