Smooth muscle tumors ofthe gastrointestinal tract

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.
