Background: Hepatitis C prevalence in Romania is 3.5%. Nowadays, the treatment of this condition comprise of interferon. One of the interferon’s side effects is the reduction of collagen synthesis, substance that is necessary in the process of abdominal wall healing.

Case report: We report the case of a 56 years old female patient, admitted in our Clinic for a giant, recurrent incisional hernia. The patient’s history was eventful: a hysterectomy for uterine fibroma in 2009, incisional hernia repair in 2010, the treatment with Interferon in 2011 and 2012 for viral hepatitis C. A well represented subcutaneous tissue is observed intraoperator, a wall defect of 15 cm in diameter with a 5 mm thick muscle aponeurosis lay. We performed abdominal wall plasty by components separation technique, reinforced with a polypropylene mesh disposed on lay. Postoperative analgesia was provided by inserting a wound catheter through which Ropivacaine 0,5% was continuously injected for 72 hours. The postoperative evolution was uneventful, the patient being discharged 7 days after the surgical intervention.

Conclusions: The treatment with Interferon of hepatitis C can favor the recurrence of an incisional hernia. The Oscar Ramirez procedure seemed to be the best choice for surgical treatment of this giant incisional hernia. Postoperative analgesia can be accomplished by a wound catheter through which Ropivacaine 5% is continuously infiltrated.
