Incisional hernias post liver transplantation: Current evidence of epidemiology, risk factors and laparoscopic versus open repair. A review of the literature

Abstract

Background/Aim: The occurrence of an incisional hernia after liver transplantation consists of a potential complication that may seriously affect the postoperative course and the quality of patient's life in general. The purpose of this study was to report the current epidemiological data, analyze the risk factors, evaluate the role of laparoscopic repair in this condition, and present the technical difficulties in the management of this special patient group. Materials and Methods: A literature search was performed through PubMed. Our criteria included all studies published from March 1982 to February 2019 in English, regarding incisional posttransplant hernias and open or laparoscopic repair. Finally, we collected 19 relevant studies. Results: Incisional hernia may occur independently of the type of abdominal incision. Risk factors are both patient- and technique-related. Conclusion: Well-organized randomized controlled studies are needed, in order to estimate the best treatment strategy for these patients.
