Recurrences in Laparoscopic Incisional Hernia Repairs: A Personal Series and Review of the Literature

OBJECTIVE: Laparoscopic repair of incisional ventral hernias with ePTFE mesh continues to evolve, with variable reporting of surgical techniques and outcomes. This report of 34 cases discusses, with a literature review of laparoscopic incisional hernia repair, specific factors associated with three recurrences. METHODS: Retrospective analysis and review of the literature. RESULTS: Thirty-two patients (16 female, 16 male), under-went 34 laparoscopic repairs: average age–54 years (27-80), average weight–207 lbs (100-300). Nineteen patients (62%) were undergoing first time repairs, 38% were redo cases and 5 cases (14%) involved previous mesh. Operating times averaged 101 minutes (45-220), and average length of stay was 1.9 days (0.6 days excluding 5 patients who required readmission), with 13 patients (38%) being discharged same-day. Two patients developed cellulitis (6%) treated without patch removal. Two enterotomies occurred (6%) both requiring patch removal. Five patients required readmission (14%), and one patient died postoperative day 29 secondary to end-stage liver disease. Three recurrences developed (9%): one secondary to missed enterotomy with reoperation, patch removal and hernia recurrence; one due to omission of suspension suture fixation; and one recurrence developed in a section of the intact old previous incision that extended beyond the original patch. Follow up has averaged 20 months (4-36). CONCLUSIONS: The laparoscopic repair of ventral and incisional hernias utilizing transabdominal placement of ePTFE patch can achieve excellent results with low morbidity in comparison with open surgical approaches. In reviewing the experience of other investigators, adequate fixation of the mesh, extension to cover the entire previous incision and standardizing the placement interval of the sutures are critical to the success of the repair.
