This study aims to describe an innovative and multipurpose technique, intragastric single-port surgery (IGS), which can be applied for abovementioned special situations and for assessing its safety, feasibility, and efficacy. Methods: IGS technique was performed through a 2\u20133\u00a0cm skin incision, where the stomach wall is exteriorized and fixed to the skin. The single-port device is inserted and intragastric access is gained for laparoscopic or endoscopic instruments. Three purposes of IGS were performed: (1). gastric intraluminal lesions resection; (2). to perform ERCP after RYGB; and (3). revision of pancreaticogastric anastomosis after pylorus-preserving pancreaticoduodenectomy. Results: IGS was performed successfully in 20 patients. Ten patients underwent gastric intraluminal lesion resection, mostly for gastric gastrointestinal stromal tumors (n = 7, 70%); all pathological specimens were with negative margin, mean operation time was 102.3 \u00b1 43.5\u00a0minutes, and mean postoperative hospital stay was 4.6 \u00b1 1.5\u00a0days. Nine patients underwent ERCP after RYGB, cleaning of the bile duct was successful in all patients (100%), and mean operation time and mean postoperative hospital stay were 140.6 \u00b1 46.3\u00a0minutes and 4.4 \u00b1 2.6\u00a0days, respectively. One patient underwent pancreaticogastric anastomosis revision. There were no mortalities in our series. Conclusions: IGS is a safe, feasible, and effective technique for gastric intraluminal lesion resection and for performing ERCP after RYGB, while it has the potential for other future applications.<\/jats:p>","DOI":"10.1177\/15533506211015386","type":"journal-article","created":{"date-parts":[[2021,4,29]],"date-time":"2021-04-29T12:54:01Z","timestamp":1619700841000},"page":"56-65","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Intragastric
