Gastrointestinal stromal tumor involving the second and third portion of the duodenum: treatment by partial duodenectomy and Roux-en-Y duodenojejunostomy.
The optimal surgical procedure for duodenal gastrointestinal tumors (GIST) remains undefined because while surgical resection clearly confers survival advantage, there is little submucosal spread in GIST and lymphatic involvement is rare. Various surgical procedures for duodenal GIST, pancreatoduodenectomy, pancreas-sparing duodenectomy, segmental duodenectomy, or local resection, have been described depending on the size and exact site of the lesion. In this report, we describe two cases of GIST involving the second and third portion of the duodenum successfully treated by partial duodenectomy with Roux-en-Y duodenojejunostomy. This surgical technique is ideal when GIST does not involve the ampulla as it avoids a pancreatoduodenectomy and has not been previously described for the management of this malignancy.
