Endoscopic full-thickness resection of a duodenal gastrointestinal stromal tumor.

ABSTRACT:

Background and aim

There is limited literature regarding endoscopic removal of gastrointestinal stromal tumors (GISTs) located in the duodenum. We present successful endoscopic submucosal dissection and exposed full-thickness resection (FTR) of an incidentally discovered duodenal GIST in an asymptomatic 65-year-old man.

Methods

The lesion was 1.4 cm and well-defined, primarily located in the submucosal layer of the posterior D2 duodenal wall and the level of the major papilla around 2 cm distal to the ampulla. Transverse mucosotomy was made followed by submucosal dissection. An IT2 knife with a protected tip was used for the majority of resection to preserve the lesion's capsular layer. Methodical dissection was performed until the lesion was removed en bloc. Endoscopic sutu
