Total Robotic Resection of Ascending Duodenal Gastrointestinal Stromal Tumor using Tubular Stapler Anastomosis: A Case Report

An obese patient was admitted to the Department of Gastrointestinal Surgery at Xiangyang Central Hospital, an affiliated hospital of Hubei University of Arts and Sciences, in June 2024 due to a gastrointestinal stromal tumor (gastrointestinal mesothelioma) of the ascending duodenum. Complete robotic excision of the gastrointestinal stromal tumor and tubular stapler insertion into the ascending duodenum were carried out. The surgeries took 190 minutes (the docking time was 30 minutes), there were approximately 10 milliliters of intraoperative hemorrhage, and there was no duodenal stenosis or contrast agent leak on the upper gastrointestinal tract. The outcomes demonstrated the technical safety and viability of using a tubular stapler to treat ascending duodenums under a total robot, as well as offering some experience in the selection of surgical techniques for GIST in specific segments.
