[A Case Report on Laparoscopic Duodenal Sleeve Resection of GIST at a Distal Portion from the Papilla Vater].

A 21-year-old woman was admitted for preshock due to severe anemia. A 5 cm gastrointestinal stromal tumor(GIST)at the jejunal flexure of her duodenum was diagnosed by enhanced CT examination. We performed a total laparoscopic pancreas- preserving duodenal sleeve resection with a 2 cm margin from the tumor. Functional end-to-end anastomosis was done with the patient lying in a right half lateral decubitus position in order to shift the weight of the tumor and duodenal mesentery to the right to prevent surgical capsule damage. We experienced one case(5.5%)of peritoneal(recurrent)GIST after laparoscopic gastrectomy. However, this is generally a safe and useful procedure for laparoscopic duodenal sleeve resection of duodenal GIST at a distal portion from the papilla Vater, when performed by a skilled team.
