Abstract
BACKGROUND: Common colorectal procedures that require access to all quadrants of the abdomen are subtotal colectomy (STC) and total proctocolectomy (TPC). These are frequently performed with a surgical robot, but multiquadrant operations have unique challenges during robot-assisted surgery. METHODS: Patients who underwent robotic STC or TPC with the da Vinci Xi surgical robot at our institution from July 1, 2016 through June 30, 2019 were identified by diagnosis and procedure codes. A technical description is provided for the techniques utilized at our institution. Outcomes included operative times (OT), supply cost and length of stay. Associated morbidity and mortality was also analyzed. RESULTS: From a review of our institution's robotic surgery data, 37 cases were identified that utilized the described technique. Of these cases, 21 were robotic STC and 16 were TPC. Total mean OT was 276.86 min (SD ± 119.49). Mean OT was further analyzed by year, which demonstrated an overall decrease in OT from 350.91 min (SD ± 46.38) in 2016 to 221.43 min (SD ± 16.46) in 2018 (p = 0.008). A total of 21 cases were performed prior to 2018. Overall OT for STC was 222.81 min (SD ± 14.54) compared to overall TPC OT 347.81 min (SD ± 34.35). Median length of stay was 5 days [25th and 75th percentiles 4, 6, respectively]. There was no 30-day mortality and only one return to operating room for mesenteric bleeding. There was a low risk of mortality associated with this technique. CONCLUSIONS: The current study provides the largest cohort of patients assessed who have undergone multiquadrant robotic STC or TPC. The study provides a detailed description of the technique utilized at our institution. There was no associated 30-day mortality and a low risk of morbidity. The data suggest that the learning curve for improved operative time is between 15 and 20 cases.
