Mesh repair of incisional Hernia: Comparison of Laparoscopic and open repair

Abstract

OBJECTIVE: To compare our results of open and laparoscopic mesh repair of incisional hernias. DESIGN: Retrospective cohort study. SETTING: Teaching hospitals, The Netherlands. SUBJECTS: All patients who had had a laparoscopic (n = 25) or an open (n = 76) mesh repair of incisional hernia between January 1996 and January 2000. INTERVENTIONS: Physical examination at the time of the study. MAIN OUTCOME MEASURES: Morbidity and recurrence. RESULTS: The groups were comparable. 11 patients (14%) developed postoperative infections after open repair and 1 (4%) after laparoscopic repair (p = 0.29). Median hospital stay was 5 days (range 1-19) in the open group and 4 (range 1-11) in the laparoscopic group (p = 0.28). The 2-year cumulative incidence of recurrence was 18% after open repair (median follow-up of 17 months (range 1-46) and 15% after laparoscopic repair (median follow-up of 15 months, range 1-44). Recurrences in the laparoscopic group were all among the first 7 cases in which the mesh was fixed with staples alone. CONCLUSION: There were fewer infections and hospital stay was shorter in the laparoscopic group, but not significantly so. Recurrence rates were comparable.
