Abstract:
Objective To investigate the clinical characteristics and surgical treatment of gastrointestinal stromal tumors (GIST) of the duodenum.Methods The clinical data of 39 patients with duodenal GISTs from 1992 to 2010 were analysed retrospectively.Results The most common symptoms of duodenal GISTs were alimentary tract hemorrhage,occuring in 18 cases of the 39 cases (46％).Clinical diagnosis established by CT in 22 cases (69％).Duodenoscopy performed in 18 cases established the definite diagnosis of GIST in 15 (83％).Duodenal GISTs were most commonly located in the descending portion of the duodenum in 27/39 cases (69％).All 39 cases received surgical treatment,with R0 resection in 34 cases,including partial resection of the duodenum in 47％ (16/34),pancreaticodenectomy in 35％(12/34),segmental resection of the duodenum in 3 cases,subtotal gastrectomy in 3 cases; One died perioperatively and postoperative complications developed in 9 cases,which were cured by conservative therapy.The 1,3,5 year survival rate was 90％,72％,41％ for those receiving R0 resection.Conclusions The abdominal CT scan with contrast and duodenoscopy are helpful to establish the diagnosis of duodenal GISTs.Surgical procedures depend on the size and site of the lesion for R0 resection.To decrease postoperative recurrence and prolong survival adjuvant therapy with Imatinib is necessary.
