Abstract: Objective To explore the methods and clinical value of transrectal ultrasound (TRUS) in detecting rectal gastrointestinal stromal tumor(GIST) with head scanning probe.Methods A total of 12 patients had the ultrasonic examination through the rectum with the head scanning probe.Preoperative ultrasonic findings were compared with the pathological results.Results Of the 12 patients,the patients were divided into three groups,including 3 cases with low-degree severity,6 cases with moderate-degree severity and 6 cases with high-degree severity.The lymph node metastasis was not found near intestines.Rectal GIST appeared as a hypoechoic mass with clear limit、regular form and expanded growth under TRUS.The CDFI showed abundant flow in the tumor and TRUS had an overall accuracy rate of 75.0%(9/12)in the diagnosis of rectal GIST.The accuracy of TRUS in the staging diagnosis of rectal GIST was 83.3%(10/12).Conclusion The TRUS with the head scanning probe is of great value for pre-operative diagnosis and staging of rectal GIST.Rectal water window and felicitous check-up technique can enhance the accuracy of TRUS.
