Incidence, predisposing factors, and results of surgical treatment of incisional hernia after orthotopic liver transplantation.

The literature provides little data about incisional herniae (IH) developing after orthotopic liver transplantation (OLTx). We evaluated the incidence, predisposing factors, and results of surgical treatment of this pathological condition. We reviewed the records of 718 consecutive OLTx performed in 623 patients between April 1986 and May 2002. Patients whose IH developed after transplantation were included in the study. We identified 31 patients (incidence, 4.9%) whose IH developed from 2 to 140 months after the transplantation. This complication was significantly more frequent in men. Important predisposing factors included: virus-correlated cirrhosis, body mass index >25, severe ascites, incision type for OLTx (bilateral subcostal extended upper midline to xiphoid), and post-OLTx complications. In 17 patients, repair of hernia was performed using direct fascial approximation, in 20 patients, it required a prosthesis. After hernia treatment, we observed no deaths but a morbidity rate of 6.4%, a mean postoperative hospital stay of 8 days and a recurrence rate of 6.4%. IH post-OLTx need surgical treatment.
