Use of Biologic Mesh for the Treatment and Prevention of Parastomal Hernias.

Parastomal hernia is a frequent complication of ostomy formation with an incidence of up to 56% depending on the type and location of the ostomy as well as the length of follow-up. This review seeks to provide concise insight into the current state of parastomal hernia repair using a hernia mesh, with a particular focus on biologic mesh. Surgical techniques and clinical outcomes of the "keyhole", modified Sugarbaker, and sandwich procedures are described. The current body of evidence on prophylactic biologic mesh placement to prevent parastomal hernia is discussed. Current evidence (while not high-quality) supports the hypothesis that prophylactic biologic mesh placement may decrease parastomal hernia rates. Further experimental and observational clinical studies are required to better understand the role of prophylactic mesh placement to prevent parastomal hernia in patients undergoing colorectal resection with permanent ostomy.
