A Post-market Observational Study With the easyEndoTM Universal Linear Cutting Stapler in Standard Laparoscopic and Robot-assisted Laparoscopic Roux-en-Y Gastric Bypass (RYGB) Surgery (SIRIUS)
January 7, 2022 updated by: Duomed
The primary purpose of this observational registry is to evaluate the safety of the easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical when used to create anastomoses during standard and robot-assisted laparoscopic Roux-en-Y Gastric Bypass (RYGB) surgery.
Stapler performance during surgery as well as post-operative pain and the clinical efficacy of the procedures will be determined as secondary objectives.

PADSS is based on the assessment of 6 criteria: vital signs (including blood pressure, pulse, temperature and respiratory rate), ambulation, nausea / vomiting, pain, surgical bleeding and fluid intake / output.
Each criterion is given a score from 0 to 2. Patients scoring ≥ 9 are considered fit for discharge, provided that the score for vital signs is not lower than 2 and that none of the other five criteria is 0, even if the total score reaches 9.
