Clinicopathological Study of 5 Cases of Duodenal Gastrointestinal Stromal Tumor

Abstract

We analyzed the clinicopathological characteristics of 5 patients with duodenal gastrointestinal stromal tumor (GIST) resected at our hospital between January 2005 and December 2015. The patients (4 males, 1 female) were aged 54 to 83 years (mean : 68 years). We suspected duodenal GIST in all patients before surgery based on endoscopy. The tumor location was in the horizontal portion in 3, descending portion in 1, and ascending portion in 1. The tumor size ranged from 25 to 75 mm (mean : 40 mm). We performed wedge resection of the duodenum in all patients. The classification was T2 in 4 and T3 in 1. The pathological stage was I in 4 and II in 1. The postoperative median follow-up duration was 52 months (range : 7-131 months). All patients were discharged at an average of 13 days (range : 10-15 days) postoperatively without complications such as pancreatic fistula or suture deficiency. All patients are alive without recurrence. In the surgical treatment of duodenal GIST, it is very important to preserve organ function.
