Ten-year trends in minimally invasive hernia repair: a NSQIP database review.

Abstract

Utilization of minimally invasive techniques for ventral and inguinal hernia repairs continues to rise. The purpose of this study was to provide updates on national utilization trends and wound complications of minimally invasive versus open ventral and inguinal hernia repairs. Data were accessed from the 2006 to 2017 National Surgical Quality Improvement Program database. All CPT codes that correlated to laparoscopic and open inguinal and ventral hernia repairs were queried. The total number of cases and wound complications, including superficial surgical site infection (SSI), deep SSI, organ space SSI, and wound dehiscence, was collected for each respective CPT code and compared for each year. IBM SPSS Statistics Software and Microsoft Excel were used to collect and analyze the data. Between 2009 and 2017, the percentage of minimally invasive inguinal hernia repairs increased from 23.1 to 37.8%, whereas the percentage of minimally invasive ventral hernias only increased from 31.5 to 36.6%. Open inguinal hernia repairs had a wound complication rate ranging from 0.60 to 0.74%, which was double the rate of minimally invasive repairs (0.24 to 0.49%) for nearly each respective year. Minimally invasive ventral hernia repairs had total wound complication rates ranging from 0.91 to 1.37%, whereas open ventral hernias had the highest total wound complication rates ranging from 5.07 to 6.26%. Over the last ten years, the utilization of minimally invasive inguinal and ventral hernia repair has increased by nearly two-fold. A larger proportion of this increase has been secondary to minimally invasive inguinal compared to ventral hernia repairs. Wound complications across all techniques remained stable or improved, and remained significantly less in the minimally invasive compared to open approaches. This study highlights the continued growth of minimally invasive techniques in hernia repair over the last decade.
