Prophylactic mesh placement in emergency midline laparotomy for intestinal perforation peritonitis: An appeal for caution.

Prophylactic mesh placement (PMP) is increasingly being used to reduce the incidence of incisional hernia after routine and emergency midline laparotomy (EML). However, such studies are not available for EMLs done solely for intestinal perforation. Patients who underwent non-absorbable PMP during EML for intestinal perforation (Group A, 15 patients) were compared with those who had a conventional abdominal wall closure (Group B, 20 patients). The incidence of wound dehiscence was significantly higher in Group A, while surgical site infection (SSI), and incisional hernia were similar in both groups. Mesh explantation was needed in half the cases. A prophylactically placed non-absorbable mesh in patients undergoing EML for intestinal perforation is associated with significantly higher rates of wound dehiscence and of mesh explantation and therefore, routine use of such a mesh appears not to be justified.
