Abstract

Background: It is unclear whether robotic utilization has increased overall minimally invasive colorectal surgery rates or if robotics is being adopted instead of laparoscopy. The goal was to evaluate whether increasing robotic surgery utilization is associated with increased rates of overall colorectal minimally invasive surgery.

Methods: The Statewide Planning and Research Cooperative System (New York) was used to identify patients undergoing elective colectomy or proctectomy from 2009 to 2015. Individual surgeons were categorized as having increasing or non-increasing robotic utilization (IRU or non-IRU, respectively) based on the annual increase in the proportion of robotic surgery performed. The odds of surgical approach across the study period were evaluated with multinomial regression.

Results: Among 72,813 resections from 2009 to 2015, minimally invasive-surgery increased (47-61%, p < 0.0001). For colectomy, overall minimally invasive-surgery rates increased (54-66%, p < 0.0001), laparoscopic remained stable (53-54%), and robotics increased (1-12%). For proctectomy, overall minimally invasive-surgery rates increased (22-43%, p < 0.0001), laparoscopic remained stable (20-21%), and robotics increased (2-22%). Over the study period, 2487 surgeons performed colectomies. Among 156 surgeons with IRU for colectomies, robotics increased (2-29%), while laparoscopy decreased (67-44%), and open surgery decreased (31-27%). Overall, surgeons with IRU performed minimally invasive colectomies 73% of the time in 2015 versus 69% in 2009. Over the study period, 1131 surgeons performed proctectomies. Among 94 surgeons with IRU for proctectomies, robotics increased (3-42%), while laparoscopy decreased (25-15%), and open surgery decreased (73-44%). Overall, surgeons with IRU performed minimally invasive proctectomy 56% of the time in 2015 versus 27% in 2009. Patients in the latter study period had 57% greater odds of undergoing robotic surgery.

Conclusions: Overall, minimally invasive colorectal resections increased from 2009 to 2015 largely due to increasing robotic utilization, particularly for proctectomies.
