Clinical Trial Summary

The general objective of the study is to confirm the medium/long-term safety and clinical performance of the CELLIS Rectopexy membrane used in rectal prolapse repair by ventral rectopexy and to identify emerging risks in comparison to the clinical data related to other types of fixation material.

The present study will be a prospective multicentric non-randomized and non-controlled trial involving 55 patients followed for 24 months. The study will be conducted in France in 3 investigational centres.

Description:

The study will be prospective, multicentric, single-arm, observational (non-interventional) to evaluate the safety and performance of CELLIS Rectopexy used in rectal prolapse repair by ventral rectopexy.

All evaluations will be performed and products used according to the usual practice, without additional or unusual diagnostic, treatment and monitoring procedure.

The study will be conducted in France in 3 investigational centres including 55 patients scheduled for the repair of rectal prolapse.

Each patient will participate in one assessment period including a screening visit, followed by the day of surgical procedure and a hospitalization period. Patients will return for ambulatory visits at Day 30 (+/- 7 days), Month 6 (+/- 2 weeks), Month 12 (+/- 2 weeks) and Month 24 (+/-2 weeks).

The surgical technique used to repair rectal prolapse will be either Laparoscopic Ventral Rectopexy (LVR) or a robotic assisted rectopexy with the use of the da Vinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of adverse events including reoperation and removal of the mesh	Percentage	From the surgical procedure through the entire 24-month follow-up period
Secondary	Rate of structural defect recurrence based on rectal examination with/without adjunctive investigations as clinically indicated	Percentage	Throughout the study until end of the 24-month follow-up period
Secondary	Rate of structural defect recurrence requiring reoperation	Percentage	Throughout the study until end of the 24-month follow-up period
Secondary	Symptoms evolution: presence or absence of symptoms (constipation, fecal incontinence, bloody and/or mucous rectal discharge (soiling), unsatisfactory sexual activity, pain)	Described at each visit and compared to baseline	At baseline and at 30-day, 6-month, 12-month and 24-month follow-up visits
Secondary	Symptoms severity scored by a visual analog scale (0-10; 0 corresponding to no impact on life and 10 corresponding to extreme, incapacitating impact)	Described at each visit and compared to baseline	At baseline and at 30-day, 6-month, 12-month and 24-month follow-up visits
Secondary	Rate of symptoms recurrence	Percentage	Throughout the study until end of the 24-month follow-up period
Secondary	Severity of disease by the use of the Cleveland Clinic Incontinence Score (CCIS)	Change from screening of total score at each follow-up visit. This scoring system cross-tabulates frequencies and different anal incontinence presentations (Gas/Liquid/Solid/Pad use/Need for lifestyle alterations) and sums the returned score to a total of 0-20 (where 0 = perfect continence and 20 = complete incontinence).	At baseline and at 30-day, 6-month, 12-month and 24-month follow-up visits
Secondary	Severity of disease by the use of the Obstructed Defecation Score (ODS)	Change from screening of total score at each follow-up visit. The ODS score is the sum of all points, with a minimum of 0 point and a maximum possible of 31 points with higher scores meaning worse outcome.	At baseline and at 30-day, 6-month, 12-month and 24-month follow-up visits
Secondary	Quality of life by the use of the Short Form (36) Health Survey (SF-36) questionnaire	Change from screening of each domain score and total score at 24-month. The SF-36 has eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0 - 100 with lower scores = more disability, and higher scores = less disability	At baseline and at 24-month
Secondary	Description of device deficiency: inadequacy of a medical device with respect to its identity, quality, durability, reliability, safety or performance. Device deficiencies include malfunctions, use errors, and inadequate labelling.	Summarized and listed	During the surgical procedure
