Brief summary

The use of regenerative medicine in colorectal surgery constitutes an entirely new therapeutic principle. The aim of this new therapeutic approach is to reduce the anastomotic leak rate and minimise morbidity and mortality. The literature identifies the leak rate for colorectal operations as 3-39%.

Detailed description

Introduction: The use of regenerative medicine in colorectal surgery constitutes an entirely new therapeutic principle. The aim of this new therapeutic approach is to reduce the anastomotic leak rate and minimise morbidity and mortality. The literature identifies the leak rate for colorectal operations as 3-39%. Methods: This is a prospective, multi-centre descriptive study commencing in June 2018. As part of the elective laparoscopic colorectal surgery, an autologous fibrin matrix was used as part of anastomotic technique in conjunction with activated thrombocytes (Obsidian ASG®). During anastomosis, this matrix was applied after resection onto the colorectal tissue surfaces with the aim of triggering tissue regeneration and improved wound healing.
