Abstract Background Parastomal hernia (PSH) is the most common complication of stomas associated with significant morbidity. Prophylactic mesh in preventing PSH is less well studied, and evidence is conflicting. We compare PSH rates in patients in whom 3D intraperitoneal mesh was and was not used prophylactically in a cohort of rectal cancer patients undergoing elective curative resection. Method Retrospective data from the Somerset Database and Electronic Patient Record were collected on patients under a single consultant surgeon between May 2016 and December 2021. Follow up was for a minimum of 2 years (excluding deaths). Appropriate statistical tests of difference significance were performed for proportions of categorical data, and time to hernia occurrence in patients with and without Dynamesh IPST placement. (Fisher’s Exact test; Kaplan Meier) Results From 397 colorectal cancer patients under the care of a single surgeon, 223 had elective surgery with curative intent, of which 63 (28%) underwent total mesorectal excision (TME) (30 TME P=0.039. Post operative complications and pain scores differed only slightly. Time to hernia development did not differ between groups. Conclusions Use of prophylactic mesh during permanent stoma formation in our practice appears safe, and effective in preventing PSH. Further studies may answer the question “Should 3D collared mesh be routinely placed during the formation of permanent stomas to prevent parastomal hernia?”
