Continuous Locked Non-barbed Suture for Mesh Fixation During Laparoscopic Ventral Rectopexy for Severe Rectal Prolapse

Introduction Laparoscopic ventral rectopexy could be considered the gold standard procedure for rectal prolapse because provides the potential to combine the success rates of an abdominal approach with the faster recovery associated with a minimally invasive technique. Tissue dissection and mesh placement may also be facilitated by the magnification and field of view permitted by the laparoscopic approach. These benefits must be balanced against a longer operating time from 150 to 250 minutes according to surgeons' experience. This prospective randomized pilot study is aimed to verify if the operative time of a standard laparoscopic ventral rectopexy for the treatment of rectal prolapse could be further reduced using using a continuous locked suture vs. conventional 6-points single suture for mesh fixation.

Secondary endopoints of this comparison are incidence of intra- or postoperative complications estimated blood loss, postoperative pain (evaluated by VAS), days of hospitalization and costs for the health care system.

Statistical Analysis and Study Design This is a single Institution prospective randomized clinical trial conducted at the Pia Fondazione Panico of Tricase, Italy.

To have an imbalanced results and to reduce any bias, a randomization list has been checked.

Probability (p) values will be considered to be statistically significant at the <0.05 level.

There will be recruited 25 patients to treat using continuous locked suture and 25 patients to treat with standard 6-points single suture for mesh fixation comparing these two techniques in terms of operative time, estimated blood loss and other intra- or post operative complications, postoperative pain, days of hospitalization, costs. All patients will be adequately informed and inserted in the study only after having read and signed an informed consent. Diagnostic, clinical and surgical data of each patient will be prospectively recorded. At the end of the procedure, a schedule will be compiled with intraoperative data. All clinical and histologic data will be recorded prospectively using a database. Pain associated with the procedure will be evaluated by a subjective assessment (analysis of VAS scale values reported by patients at 8 and 24 hours after surgery). Post-operative complications will be evaluated during the first 30 days after surgery according to Dindo's classification.
