Abstract
We made a clinical study on rectal tumors undergoing transanal endoscopic microsurgery (TEM) in terms of recurrence and prognosis. A total of 68 cases operated on at the hospital from 1994 to April 2004 were enrolled in this study, whose rectal tumors which were located from 3cm to 18cm distal from the anal verge were excised by using the Buess rectoscope. There were 37 cancers, 16 adenomas, nine carcinoids, and nine other lesions. Local recurrence occurred in three cases, but all three cases were of recurrence of only adenoma component and were radically cured by another TEM or EMR. Three patients died of other disease (associated neoplasm). There were seven patients performed laparotomic radical operation based on the histological diagnosis of excised material with TEM. Of the seven patients, two patients had lymph node involvement, but all the two patients have been alive, as of 4-7 years after the operation.
It is thought that TEM is a useful therapeutic strategy for rectal tumors.
