Simple segmental resection of the second portion of the duodenum for the treatment of gastrointestinal stromal tumors.
BACKGROUND
Adequate surgical procedure for gastrointestinal stromal tumors (GISTs) arising in the second portion of the duodenum remains controversial.


METHODS
Segmental resection of the second portion of the duodenum and Roux-en-Y reconstruction was performed in two patients with duodenal GISTs. In case 1, a huge tumor arising from the second portion of the duodenum occupied the right upper quadrant of the abdomen. Preoperative treatment using imatinib mesylate decreased the tumor size from 22 to 8 cm. In case 2, the tumor was located in the second portion of the duodenum longitudinally. In both of the cases, the major papilla was preserved.


RESULTS
The postoperative course was uneventful, and they were discharged on day 11. Surgical margins were negative.


CONCLUSIONS
The present simple segmental duodenectomy can be applied in the treatment of GISTs or other low-grade malignancies.
