We performed transanal local excision of anal canal cancer in a 51-year-old man. The tumor was detected as an Isp polyp(7 mm)on the dentate line, by colonofiberscopic examination. Pathological findings indicated adenocarcinoma(T1b). The patient desired preservation of anal function, and hence refused abodominoperineal rectal transection with lymph node dissection. We obtained informed consent for recurrence, and observed the patient rigorously. No recurrence or metastasis has been detected 3 years and 3 months after tumor excision. We propose that transanal local excision might be a treatment option for early stage cancer of the anal canal.
