The transanal resectoscope: an under-used instrument?

The use of the urological resectoscope in the treatment of rectal tumours has been described in detail. We report the use of the purpose built transanal resectoscope in the treatment of 34 patients. Fourteen patients had villous adenomas and all but one were relieved of symptoms. Of 20 patients with rectal carcinoma, three presented with acute intestinal obstruction and three had rectal stump recurrences. Palliation was excellent in patients with general symptoms, but the results were disappointing for rectal stump recurrences. Transanal resection (TAR) is a novel form of treatment for patients with rectal obstruction. Two patients in this study had their obstruction successfully relieved by transanal resection alone. This allowed formal bowel preparation and full pre-operative assessment. We feel that this technique is under-used and that the results of treatment justify more widespread acceptance of the procedure.
