Endoscapic polypectomy or incisional enucleation was performed to 10 cases of esophageal submucosal tumor, from March, 1984 to January, 1988, using biopsy forcep, loop snare with high frequency electric current. The results were as follows. 1) In 10 cases 3 were male and 7 were female, with mean age 49. 2) Tumors were located lower esophagus in 5 cases and middle esophagus in 5 cases. 3) The presenting symptoms were mainly nonspecific, not related to underlying submucosal tomor. 4) In 8 of 10 cases, the procedure was performed completely, and so tumors were removed successfully. And in 2 cases, only biopsy for pathologic diagnosis was performed. 5) Results of histologic examination of these tumors were leiomyoma in all cases, In conclusion, we recommand endoscopic polypectomy or incisional enucleation as safe and effective method for esophageal submucosal tumor to make correct pathologic diagnosis and to treat the tumor.
