Abstract:
Objective To investigate the diagnostic value of EUS with miniprobe on upper gastrointestinal tract mesenchymal tumor(GIMT).Methods The EUS features of 38 patients with GIMT who underwent EUS with miniprobe were studied retrospectively,and the results were compared with the postoperative pathological findings.Results Among 38 GIMT cases detected by EUS,there were 25 cases of gastrointestinal stromal tumor,11 cases of leiomyoma,and 2 cases of leiomyosarcoma.Postoperative histopathological and immunohistochemical examinations confirmed 28 cases of stromal tumor.In which 6 cases were high-risk GIST,8 cases were leiomyoma,1 case was leiomyosarcoma,and 1 case was neurofibroma.The accuracy of diagnosis with EUS was 89%.Conclusion EUS is an accurate method in diagnosis of submucosal tumors,which can make better differentiation diagnosis between GIMT and other submucosal tumors.
