Endoscopic transanal resection of rectal adenomas using the  urological resectoscope.
OBJECTIVE
Large sessile rectal adenomas are often difficult to excise and several different techniques have been described. This study evaluates the results of adenoma excision by endoscopic transanal resection using the urological resectoscope by a single surgeon in a UK district general hospital.


METHODS
Between January 1989 and November 2004, data on all patients treated by endoscopic transanal resection of benign rectal tumours using a urological resectoscope (ETAR) were prospectively collected and analysed.


RESULTS
Forty patients (50% male, median age 72 years) underwent a total of 81 endoscopic transanal resections. The tumour characteristics were: size > 2 cm (83%), location in lower 2/3 of rectum (83%) and extensive circumferential carpet-like appearances (13%). Fifty percent of the patients required only one procedure to achieve clearance. Mean operative time was 26 min (range 10-65 min). Seventy-eight percent of the patients were discharged home within 24 h. Postoperative morbidity was 8% and in-hospital mortality was zero. Histology revealed severe dysplasia in 48% of the tumours and five patients were incidentally found to have foci of rectal adenocarcinoma. With a median follow-up of 47 months (range 2-162 months), local recurrences occurred in 13% (n = 5) of patients. All, except one, were treated successfully with further endoscopic transanal resections.


CONCLUSIONS
ETAR is simple and safe for managing rectal adenomas.
