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
- Conditions
- ObesityRoux-en-Y Gastric Bypass
- Interventions
- Device: easyEndoTM Universal Linear Cutting Stapler and reloads (Ezisurg Medical)
- Registration Number
- NCT04543526
- Lead Sponsor
- Duomed
- Brief Summary
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.

Group Intervention Description Obese patients easyEndoTM Universal Linear Cutting Stapler and reloads (Ezisurg Medical) Obese patients eligible for standard laparoscopic or robot-assisted laparoscopic RYGB surgery.
- Primary Outcome Measures
Name Time Method Safety - Length of stay at the intensive care unit. At discharge, up to 1 week. Number of days at the intensive care unit after the index procedure.
Safety - Number of re-interventions and number of participants with (serious) adverse events Follow-up 4: 24 months after the procedure. Number of re-interventions and number of participants with (serious) adverse events ≥ grade II Clavien-Dindo.
Safety - Length of stay at the intensive care unit At index procedure. Number of days at the intensive care unit after the index procedure.
Safety - Conversion rate to laparotomy At index procedure. Number of conversions to laparotomy during the index procedure
Safety - Length of stay in the hospital by the modified Post-Anesthesia Discharge Scoring System (PADSS) At discharge, up to 1 week. he Modified PADSS guarantees safe discharge. 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.
- Secondary Outcome Measures
Name Time Method Post-operative change in weight Follow-up 4: 24 months after the procedure Weight loss 24 months after the surgical procedure as compared to the patients' weight at baseline.
Number of participants with a post-operative change of cormorbidities Follow-up 4: 24 months after the procedure Comorbidities (diabetes mellitus, peripheral arterial disease, coronary arterial disease, sleep disordered breathing, hypertension, dyslipidemia, hypercholesterolemia, hypertriglyceridemia, asthma, congestive heart failure, degenerative joint disease, gastroesophageal reflux, chronic obstructive pulmonary disease, use of immunosuppressants) 24 months after the surgical procedure as compared to the patients' comorbidities at baseline.
Device performance - Technical success of the surgical procedure performed with the device At index procedure Number of procedures with technical success defined as bariatric surgery as intended, without technical difficulties and without conversion to laparotomy.
Post-operative food tolerance by means of the food tolerance questionnaire Follow-up 4: 24 months after the procedure Food tolerance by means of the food tolerance questionnaire. The food tolerance questionnaire allows to score the patients' satisfaction regarding food intake and food tolerance after bariatric surgery. The patients' interpretation of food intake is scored between 1 (very poor) and 5 (excellent). A cumulative score, varying between 1 and 27 is derived, with 27 representing an excellent food tolerance.
Device performance - Scoring of operator satisfaction At index procedure Scoring of: easy of intra-abdominal device positioning, grasping/climbing force, sharpness of the blades, staple-line formation, device stability, device maneuverability, battery power, 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.
Post-operative pain by means of the Visual Analogue Scale (VAS) Follow-up 1: 1 month after the procedure Assessment of the worst post-operative abdominal pain since discharge by means of the VAS, which contains a 0 to 100 grading scale with 0 equaling no pain and 100 equaling the worst conceivable pain.
