OC-033 SHORT-TERM OUTCOMES OF MINIMALLY INVASIVE RETROMUSCULAR VENTRAL HERNIA REPAIR USING AN ENHANCED VIEW TOTALLY EXTRAPERITONEAL (ETEP) APPROACH: SYSTEMATIC REVIEW AND META-ANALYSIS

Abstract

Abstract Background The enhanced view totally extraperitoneal (eTEP) approach is becoming increasingly more widely accepted as a promising technique in the treatment of ventral hernia. However, evidence is still lacking regarding the perioperative, postoperative and long-term outcomes of this technique. The aim of this meta-analysis is to summarize the current available evidence regarding the perioperative and short-term outcomes of ventral hernia repair using eTEP. Study Design A systematic search was performed of PubMed, EMBASE, Cochrane Library and Web of Science electronic databases to identify studies on the laparoscopic or robotic enhanced view totally extraperitoneal (eTEP) approach for the treatment of ventral hernia. A pooled meta-analysis was performed. The primary endpoint was focused on short-term outcomes regarding perioperative characteristics and postoperative parameters. Results A total of 13 studies were identified involving 918 patients. Minimally invasive eTEP resulted in a rate of surgical site infection of 0% [95% CI 0.0–1.0%], a rate of seroma of 5% [95% CI 2.0–8.0%] and a rate of major complications (Clavien-Dindo III-IV) of 1% [95% CI 0.0–3.0%]. The rate of intraoperative complications was 2% [95% CI 0.0–4.0%] with a conversion rate of 1.0% [95% CI 0.0–3.0%]. The mean hospital length of stay was 1.77 days [95% CI 1.21–2.24]. After a median follow-up of 6.6 months (1–24), the rate of recurrence was of 1% [95% CI 0.0–1.0%]. Conclusion Minimally invasive eTEP is a safe and effective approach for ventral hernia repair, with low reported intraoperative complications and good outcomes.
