To prevent this intraoperative tumor seeding, we developed laparoscopy\u2010assisted full\u2010thickness resection (LAFTR) of the duodenum for GIST with ulceration. Here, we present the preliminary results of LAFTR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Three patients with duodenal GIST with ulceration underwent LAFTR. LAFTR consists of four major procedures: (i) a laparoscopic Kocher maneuver (mobilization of the pancreatoduodenum); (ii) the creation of a small upper median laparotomy; (iii) the extracorporeal completion of the full\u2010thickness resection under direct vision; and (iv) extracorporeal hand\u2010sewn closure of the duodenal defect.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>LAFTR was successfully performed without any intraoperative adverse events. The mean operating time and estimated blood loss were 182 min and 34 mL, respectively. Postoperative contrast roentgenography showed neither duodenal deformity nor disturbance of gastroduodenal emptying in any of the patients. None of the patients developed peritoneal recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>LAFTR can eliminate the possibility of peritoneal or port\u2010site seeding of tumor cells because the duodenotomy and tumor excision are performed extracoporeally. Meticulously hand\u2010sewn closures of the duodenal defect can minimize the possibilities of anastomotic insufficiency and deformity. LAFTR is a feasible, safe, and minimally invasive treatment for patients with GIST with ulceration in the first and second portions of the duodenum.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ases.12377","type":"journal-article","created":{"date-parts":[[2017,4,7]],"date-time":"2017-04-07T06:14:41Z","timestamp":1491545681000},"page":"388-393","source":"Crossref","is-referenced-by-count":4,"title":["Laparoscopy\u2010assisted
