OC-031 INCIDENCE AND RISK FACTORS FOR RECURRENCE OF RIVES-STOPPA REPAIR FOR INCISIONAL HERNIAS. TWENTY-YEAR RETROSPECTIVE ANALYSIS OF LONG-TERM OUTCOMES OF DIFFERENT MESH REPAIRS

Abstract

Abstract Objective the aim of this study was to determine the long-term recurrence and complication rates following Rives-Stoppa repair of midline incisional hernias with different types of synthetic materials. Patients and Methods medical files of 1628 patients with midline incisional hernias who underwent abdominal wall reconstruction using Rives-Stoppa repair between January 1999 and December 2019 were reviewed. All patients followed up after 1 month, 6 months, and 1year later and after that yearly. Results until 2007, 674 patients were operated on with available meshes for that time (mosquito net – 135, polyester mesh – 322, and polypropylene mesh – 217). After 2007, polypropylene meshes were used in 1054 patients (heavyweight in 428 patients and lightweight meshes in 626). The global recurrence rate after a mean follow-up of 96.5 months in the first group of patients was 13.3% and in the second group was 7.13% (mean follow-up of 108.4 months). The infection rate was 16.8% versus 9.2% with an increased incidence at 30 days (84 vs 62 patients). The hematoma rate was equally distributed. Seroma formation was almost 2.5-fold increased in the first group of patients (21.3% vs 8.7%). Increased rate of seroma formation were associated with mosquito net (OR = 1.7; 95% CI = 0.5–1.3; p=o.o2), heavyweight type type (OR = 0.9; 95 CI = 0.07–0.4; p=o.o31). Infection was associated with the usage of mosquito net, heavyweight type, and polyester mesh. Conclusions the lightweight mesh offers a safe method for abdominal wall reconstruction.
