168 Outcomes for Patients Undergoing Upper Gastrointestinal Robotic Surgery in a Tertiary Centre

Abstract Aim To evaluate the outcomes for patients undergoing robotic assisted (RAS) upper gastrointestinal (GI) surgery following its introduction in a tertiary centre. Method Patients undergoing RAS upper GI procedures between 04/01/2021 and 07/04/2025 in Aberdeen Royal Infirmary were included. Patients' electronic records were reviewed to collect demographics, procedure undertaken, length of stay, readmission rate, any post operative complications (classified by Clavien Dindo) and open conversion rate. The RAS system in use during this study was the Da Vinci Xi (Intuitive Surgical Operations). Results 225 patients were included in this study. The median age was 57 years (range 25-83) and 165 (73%) were female. Patients underwent the following type of procedures; cholecystectomy (n=76 [33.8%]), anti-reflux (n=75 [33.3%]), bariatric (n=31[13.8%]), motility (n=20 [8.9%]), gastric resection (n=19 [8.4%]) and other (n=4 [1.8%]). The median length of stay was 3 days (range 0 – 89 days) and 10 (4.4%) patients had a readmission within 30 days of their procedure. Forty (17.8%) patients were recorded experiencing a complication within 30 days of their procedure with 10 (25%), 16 (40%), 10 (25%), 3 (7.5%) and 1 (2.5%) classified as Clavien Dindo 1, 2, 3, 4 and 5, respectively. One (0.4%) patient required a conversion to open. Conclusions RAS upper gastrointestinal surgery has successfully been integrated into routine practice in this tertiary centre. Further evaluation is required to assess long term outcomes and applicability to major upper GI resection surgery.
