Long-term survival after endoscopic transanal resection of rectal tumours

Abstract

The outcome and survival of 120 consecutive patients of median age 78 years with rectal tumours who underwent endoscopic transanal resection were assessed. Thirty-eight patients (32 per cent) were treated for large villous adenoma. These patients underwent a median of 2 (range 1-5) resections and the overall 5-year survival rate was 78.2 per cent. Of 82 patients with rectal cancer, 33 (28 per cent of the 120) had tumours amenable to conventional surgery but for the patient's age or infirmity. The 5-year survival rate of these patients was 29.7 per cent. Endoscopic transanal resection was used to palliate the symptoms of 49 patients (41 per cent) with rectal cancer; the 5-year survival rate was 13.7 per cent. Excellent long-term outcome may be achieved with endoscopic transanal resection for patients with benign rectal tumours. This approach also gives acceptable results for selected patients with rectal cancer in whom age, extent of disease or concurrent illness preclude conventional surgical resection.
