Abstract

Life Sciences & Biomedicine Science & Technology Surgery
Introduction: Gastric gastrointestinal stromal tumors (GISTs) located at the gastroesopha-geal junction (GEJ), lesser curvature, posterior gastric wall, or antrum present challenges for gastric function preservation. The aim of this study was to evaluate safety and effec-tiveness of robot-assisted resection of gastric GIST in challenging anatomic locations.Methods: This was a single-center case series of robotic gastric GIST resections in chal-lenging anatomic locations performed from 2019 to 2021. GEJ GISTs are defined as tumors within 5 cm of the GEJ. Location of the tumor and distance from the GEJ were determined from the endoscopy report and/or cross-sectional imaging and operative findings.Results: There were 25 consecutive patients who underwent a robot-assisted partial gas-trectomy for a gastric GIST in challenging anatomic locations. Tumors were located at the GEJ (n = 12), lesser curvature (n = 7), posterior gastric wall (n = 4), fundus (n = 3), greater curvature (n = 3), and antrum (n = 2). Median distance of tumor from GEJ was 2.5 cm. Both GEJ and pylorus were successfully preserved in all patients regardless of tumor location. Median operative time was 190 min with a median estimated blood loss of 20 mL and no conversion to open approach. Median hospital stay was 3 d with solid diet intake starting 2 d after surgery. Two (8 %) patients had Grade III or higher postoperative complications. Median tumor size upon resection was 3.9 cm. Negative margins were obtained in 96.3%. There was no evidence of recurrent disease with a median follow-up of 11.3 mo.Conclusions: We demonstrate the safety and feasibility of using the robotic approach to facilitate function preservation gastrectomy in challenging anatomic locations without compromising oncologic resection.& COPY; 2023 Elsevier Inc.
