Clinical Trial Summary

Anastomotic insufficiency remains one of the most significant problems after rectal resection.The complications following anastomotic insufficiency leads to increased morbidity and mortality with subsequent prolongation of hospital stay and higher costs. This study is an investigation of the benefit of using an autologous platelet-rich fibrin matrix (Obsidian ASG®) for treatment of anastomosis during rectal surgery - a single-blind, randomized, multicenter pilot study with enrollment of 2x220 patients The main objective of the study is to investigate on an exploratory basis whether the use of Obsidian ASG® during rectal resection reduces the frequency of postoperative anastomotic insufficiency compared to standard anastomotic technique. The secondary objectives of the study are to investigate on an exploratory basis: - The frequency of anastomotic insufficiency (ISREC Criteria) severity - Staple line bleeding requiring surgical intervention - The duration of postoperative hospitalization are reduced when using Obsidian ASG ® compared with standard anastomotic treatment alone. are reduced when Obsidian ASG ® is added to the standard of anastomotic treatment compared with standard anastomotic treatment alone.
