Umbilical Hernia Repair in Cirrhotic Patients With Ascites: A Systemic Review of Literature.

BACKGROUND: Umbilical hernia is a common abdominal complication in cirrhotic patients. The incidence of umbilical hernias can be up to 20% in the presence of ascites. However, there is no consensus regarding the optimal management of umbilical hernias in cirrhotic patients. The purpose of this study is to review the management of umbilical hernias in cirrhotic patients with ascites.

METHODS: A search of the available literature in English since 1980 was performed using PubMed, the Cochrane Library, and a search of relevant journals and reference lists. The search terms included "umbilical hernia," "ascites," "cirrhosis," and any derivatives of these terms, and the literature search identified all the relevant publications.

RESULTS: Thirty-three relevant articles published in the language of English were identified. Fourteen studies involved the management of refractory ascites in cirrhotic patients. Twenty-four studies included cirrhotic patients receiving elective or emergency surgery. Because of much lower morbidity and mortality in elective surgery than in emergency surgery, many authors advocated early elective repair of uncomplicated umbilical hernias in cirrhotic patients. Of these, 2 studies described laparoscopic umbilical hernioplasty, with a significant lower morbidity and hernia recurrence than open repair. Fifteen studies described the use of prosthetic mesh umbilical hernia repair in cirrhotic patients, which was associated with minimal wound-related morbidity and markedly lower recurrences.

CONCLUSIONS: Our results indicate that early elective repair of uncomplicated umbilical hernias is recommended in cirrhotic patients with tolerable hepatic functional reserve or when the expected time for liver transplantation is >3 months. Umbilical hernias are supposed to be corrected in the process of liver transplantation, provided that patients could have a better prospect to be transplanted within 3 months. Control of ascites is a crucial part to successful outcomes of umbilical hernia repair. Large volume paracentesis, concomitant peritoneovenous shunting with herniorrhaphy and transjugular intrahepatic portosystemic shunting can be applied to control refractory ascites. Emergency repair of umbilical hernias is indicated in cirrhotic patients with ascites when complications develop.
