Purpose:
Hernia repair is a common procedure; however, an overview is lacking regarding the impact of annual surgeon volume and total surgical experience on the outcome of hernia repair. We aimed to explore the impact of annual surgeon volume and total surgical experience on outcomes of groin and primary ventral hernia repair.
Methods:
This systematic review followed the Prefered Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. A protocol was registered at PROSPERO (CRD42020176140). PubMed, EMBASE, and Cochrane CENTRAL were searched. We investigated recurrence rates after groin and primary ventral hernia repair reported according to annual surgeon volume or total surgical experience with at least 6 months follow-up. Surgeons were pooled in three overlapping categories: high-volume (> 50 cases/year), medium-volume (11-50 cases/year) and low-volume (≤ 25 cases/year).
Results:
Ten records for groin hernia and one for primary ventral hernia were included. The median (range) recurrence rates after laparoscopic groin hernia repair for high, medium, and low-volume surgeons were 2.6% (2.3-3.0), 2.4% (0.7-4.6), and 4.2% (1.0-6.8), respectively. The median (range) recurrence rate after open groin hernia repair for high, medium, and low-volume surgeons were 2.1% (2.0-2.2), 1.7% (1.6-2.3), and 2.4% (2.2-5.0). The groin hernia recurrence rate seemed to increase when annual surgeon volume decreased below 25 cases/year. For primary ventral hernia, increased annual surgeon volume was associated with decreased reoperation rate.
Conclusion:
High-volume surgeons seemed to have lower rates of hernia recurrence after groin as well as primary ventral hernia repair and our data supports the need for centralization of groin hernia repair on individual surgeons.
