Clinical features and surgical management of duodenal stromal tumors / 中国普通外科杂志

ABSTRACT

Objective To investigate clinicopathological features、diagnosis and surgical treatment of duodenal stromal tumors. Methods A retrospective clinical analysis was made in 23 cases of duodenal stromal tumors admitted from 1995 to 2004. Results Melena and abdominal pain was the most common presenting symptom. Complete resection was achieved in all cases, including pancreatoduodenectomy in 13 cases, by pylorus-preserving pancreatoduodenectomy in 3 cases, and tumor enucleation in 7 cases. The mean size of the tumor was 6. 6 cm (2 - 21 cm) , among them 10 cm in 6. Pathologically tumors less than 5 cm were all of potential malignancy, whereas those larger than 5 cm were malignant. Follow-up of 2 months to 9 years found all cases alive and healthy except for one who died of liver metastasis one year postoperatively. Conclusion Duodenal stromal tumors were low malignancy tumors. Aggressive surgery is the choice of treatment. Favorable prognosis is expected after complete surgical excision.
