Abstract
BACKGROUND: Laparoscopic ventral hernia repair (LVHR) has become widely used. This study evaluates outcomes of LVHR, with particular reference to complications, seromas, and long-term recurrence. METHODS: A review of a prospective database of consecutive patients undergoing LVHR with intraperitoneal onlay mesh (IPOM) was performed at a single institution. Patient's characteristics, surgical procedures, and postoperative outcomes were analyzed and related to long-term recurrence. RESULTS: From 2005 to 2014, 417 patients underwent LVHR. Mean age and body mass index (BMI) were 54 years and 31 kg/m2. Mesh fixation was carried out with transfascial sutures, completed with absorbable tacks (72 %), metal tacks (24 %), or intraperitoneal sutures (4 %). Intraoperative complications occurred in three patients. Overall morbidity included 8.25 % of minor complications and 2.5 % of major complications without mortality. The overall recurrence rate was 9.8 %. Median time for recurrence was 15.3 months (3-72) and median follow-up was 31.6 months (8-119). In a multivariate analysis, previous interventions (OR 1.44; CI 1.15-1.79; p = 0.01), postoperative complications (OR 2.57; CI 1.09-6.03; p = 0.03), and Clavien-Dindo score >2 (OR 1.43; CI 1.031-1.876; p = 0.02) appeared as independent prognostic factors of recurrence. Minor complications were associated with 14.7 % of recurrence and major complications with 30 % of recurrence. Emergency LVHR (6 %) did not increase the rate of complications. Overall seroma rate was 18.7 %, with 1.4 % of persisting or complicated seroma. BMI (OR 1.05; CI 1.01-1.08; p = 0.026) and vascular surgery history (OR 5.74; CI 2.11-15.58; p < 0.001) were independent predictive factors for seroma. Recurrence did not appear to be related to seroma. CONCLUSION: LVHR combines the benefits of laparoscopy with those of mesh repair. Seroma formation should no longer be considered as a complication. It is spontaneously regressive in most cases. Postoperative complications and their degree of severity appear to be independent prognostic factors for recurrence, which can be limited with a standardized technique and may make IPOM-LVHR a reference procedure.
