Objective: To explore the clinical values of endoscopic ultrasonography (EUS) on diagnosis and treatment of duodenal stromal tumor.

Methods: We compared and analyzed various kinds of imaging examinations such as body surface B-type ultrasonic examination, contrast-enhanced computed tomography (CT), conventional gastroscopy and EUS in retrospectively reviewing the clinical data of 14 patients with duodenal stromal tumor. The postoperative histological results were compared with preoperative diagnosis of all kinds of imaging examinations.

Results: A total of 14 patients underwent B ultrasonic examination (7 cases found the lesions); 13 patients underwent CT examination (13 cases found the lesions, while 6 cases diagnosed duodenal stromal tumor); 10 patients underwent conventional gastroscopy (7 cases found the lesions); 5 patients received EUS while 4 cases were diagnosed duodenal stromal tumor. All the patients underwent surgical treatment. The diagnose accordance rate between preoperative diagnosis in endoscopic ultrasonography and postoperative pathological diagnosis was 80%.

Conclusions: EUS could identified their internal structure, echo, exact size, depth of invasion, origin, and the relationship between adjacent tissues and organs; furthermore, differentiating the lesions from other submucosal tumors and clearly defining the diagnosis. EUS is an effective and reliable diagnostic method for duodenal stromal tumor.
