Incisional hernia in recipients of adult to adult living donor liver transplantation.

BACKGROUND

After receiving a living donor liver transplant (LDLT), an incisional hernia is a potentially serious complication that can affect the patient's quality of life. In the present study we evaluated surgical hernia repair after LDLT.

MATERIALS AND METHODS

Medical records of patients who underwent surgery to repair an incisional hernia after LDLT in Turgut Ozal Medical Center between October 2006 and January 2010 were evaluated in this retrospective study. A reverse-T incision was made for liver transplantation. The hernias were repaired with onlay polypropylene mesh. Age, gender, post-transplant relaparatomy, the type, the result of surgery for the incisional hernia, and risk factors for developing incisional hernia were evaluated.

RESULTS

An incisional hernia developed in 44 of 173 (25.4%) patients after LDLT. Incisional hernia repair was performed in 14 of 173 patients (8.1%) who underwent LDLT from October 2006 to January 2010. Relaparatomy was associated with incisional hernia (p = 0.0002). The mean age at the time of the incisional hernia repair was 51 years, and 79% of the patients were men. The median follow-up period was 19.2 (13-36) months after the hernia repair. Three patients with intestinal incarceration underwent emergency surgery to repair the hernia. Partial small bowel resection was required in one patient. Postoperative complications included seroma formation in one patient and wound infection in another. There was no recurrence of hernia during the follow-up period.

CONCLUSIONS

The incidence of incisional hernia after LDLT was 25.4% in this study. Relaparatomy increases the probability of developing incisional hernia in recipients of LDLT. According to the results of the study, repair of an incisional hernia with onlay mesh is a suitable option.
