Prophylactic Mesh Implantation in Patients Undergoing Requiring Emergency Laparatomy for the Prevention of Incisional Hernia:A Randomized Controlled Trial

Incisional hernia is a common complication in visceral surgery and varies between 11 and 26% in the general surgical population. Patients requiring emergency laparotomy are at high risk for the development of incisional hernia and fascial dehiscence. Among this population the incidence of incisional hernia in patients undergoing emergency surgery varies between 33-54%. Incisional hernias are associated with a high morbidity rate, such as intestinal incarceration, chronic discomfort, pain, and reoperation and typically require implantation of a synthetic mesh in a later second operation. Fascial dehiscence represents an acute form of dehiscence and has been observed in up to 24.1% and is associated with a mortality rate up to 44%.

The gold standard for abdominal wall closure during elective and emergency operations is a running slowly absorbable suture. In the elective situation it has been shown that prophylactic mesh implantation in high risk patients reduced the incidence of incisional hernia significantly.

The investigators and others have shown that mesh implantation in patients undergoing emergency laparotomy or in contaminated abdominal cavities are safe .

With a randomized controlled trial the investigators now aim to compare the incidence of incisional hernia after prophylactic mesh implantation versus standard of care in patients requiring emergency laparotomy.
