From January 1985 till December 1994 109 patients with rectal carcinom
a were treated by local excision, in 36 patients a radical operation w
as performed afterwards. In the assessment of tumor infiltration endos
onography was superior to rectal-digital examination. In 34 patients w
ith local excised ''low risk'' T1-carcinomas and tumor free margins no
local recurrence was observed. Two of ten patients with local excised
''low risk'' T1-carcinoma and no adequate margin of healthy tissue de
veloped a local recurrence. Regarding our results the local excision o
f ''low risk'' T1-carcinomas seems justified, if final histological wo
rkup reveals an adequate margin of healthy tissue.
