Five-year experience with the "four-before" laparoscopic ventral hernia repair.

Between 1993 and 1998, we performed a linear study of laparoscopic ventral hernia repair performed in a standard fashion using expanded polytetrafluoroethylene on 49 patients. Eighteen patients had recurrent hernias and 30 patients were morbidly obese with a body mass index >30. Conversion to open procedure was required in two patients. Patients were observed a mean of 27 months. Three patients died of unrelated causes during the observation period. Three patients developed recurrent hernias. By a follow-up survey, we found that 90 per cent of patients were "satisfied" with their operation and results. Because of decreased complications, postoperative pain, hospital stay, and hernia recurrence, the "four-before" laparoscopic repair is our preference for ventral hernias. It has been particularly useful for obese patients and patients with recurrent ventral hernias.
