Objective To investigate the diagnose and therapy of patients with smooth muscle tumors (SMTs) of gstrointestinal tract (GI). Methods A retrospective analysis was made on the clinical and pathological data of 92 patients with SMTs of GI admitted from 1982 to 1999 in Nanfang Hospital. Results Location of the lesion: 41 cases in stomach, 44 in small intestine, and 7 in large bowel. Adjuvant examinations: BUS was performed on 63 cases with positive findings in 31; CT on 27 cases with positive findings in 20; DSA on 29 cases with positive findings in 27; barium series on 45 with positive findings in 28; and small intestinoscopy on 11 cases with pasitive findings in 2. Conclusions DSA is the most effective method in diagnoses of SMTs of GI, especially for small intestinal leiomyoma. The primary treatment of GI SMTs is surgical resection.
