P1104 Shifting Surgical Landscape in Crohn's Colitis: Laparoscopic Supremacy and Robotic Upsurge

Abstract

Abstract Background Crohn's disease (CD) is a chronic inflammatory bowel disorder that can cause transmural inflammation throughout the digestive tract. When CD affects the colon, it is known as Crohn's colitis (CC), a serious condition often requiring surgical resection. Surgical trends in CC have changed significantly over the past decade, shifting towards minimally invasive surgery, with laparoscopic and robotic procedures becoming increasingly common. This study examines how surgical trends in CC have changed in recent years and predicts how they may change. Methods We conducted a retrospective analysis using the ACS-NSQIP database, focusing on patients who underwent colonic resections for CC between 2012 and 2021, including 20,109 patients. Our main goal was to examine trends in open, laparoscopic, hand-assisted, and robotic surgery. We utilized time series analysis, specifically quarter and year of admission data, and employed Vector Autoregressive (VAR) models to explore the dynamic relationships among these surgical techniques. To analyze the time trends, we reported the quarter (Q) and year of admission. These models enabled us to forecast future trends, accompanied by 95% confidence intervals, extending our predictions up until Q2 of 2025. Results As shown in Figure 1, open surgery has been the most common approach to CC since Q1 2012, accounting for 52.3% of all procedures. Laparoscopic surgery was the next most common approach, at 33.3%, followed by hand-assisted laparoscopy at 14.4%. Laparoscopy rapidly expressed market supremacy, by steadily becoming the most widespread approach by Q2 of 2017, representing 42.2% of CC surgery and peaking in Q2 2020 at 43.5%. This growth in laparoscopy came at the expense of open surgery, which experienced a significant decline, reaching its lowest point of 28.5% in Q2 2021. Hand-assisted procedures gradually increased in popularity over the years but remained less popular than open and laparoscopic methods, peaking at 24.0% in Q4 2019. Robotic procedures experienced slow but steady growth, from 1.9% in Q1 2013 to 10% in Q2 2021. Future trends suggest that laparoscopy will continue to grow steadily, reaching 45% (95% CI 28.2-61.7%) by the end of our prediction period. Robotic surgery is poised to significantly shift CC surgery trends, with resections expected to reach 12.6% (95% CI 9.3-15.8%) by Q2 2025, while a subsequent decline in open procedures to 20.8% (95% CI 0-43%). Conclusion Laparoscopic surgery has emerged as the favored surgical approach in CC and is expected to maintain its supremacy into the near future. Open colonic resections are anticipated to decline, making way for the increasing prevalence of robotic surgery.
