[Prophylaxis of parastomal, perineal and incisional hernias in colorectal surgery].

This article gives an overview of the relevant evidence from the literature on the topic of prophylactic use of meshes to prevent incisional and parastomal hernias in colorectal surgery. In addition, based on a structured literature search the incidence of hernias in colorectal surgery over the past 5 years was analyzed. A slight majority (54%) of articles recommended the use of prophylactic mesh implantation in colorectal surgery. The prophylactic use of meshes appears to reduce the risk of hernias in colorectal surgery but is associated with a slightly increased perioperative wound infection rate. Parastomal hernias are associated with higher incidence rates compared with incisional hernias and also appear to benefit more from prophylactic mesh implantation. The evidence in the literature is still unclear regarding the use of synthetic or biological implants due to the lack of randomized controlled trials. Perineal hernias were excluded from the analysis due to the incomparability of the mainly casuistic literature. An overview is given in the discussion. The analysis of the literature and also in reflection of our own experience comes to the conclusion that the disrupted integrity of the abdominal wall due to the operation should be prophylactically reinforced with a mesh after colorectal surgery. An evidence-based recommendation is not possible based on the current state of research on implantation techniques, e.g. onlay, sublay intraperitoneal onlay mesh (IPOM) and selection of the implant.
