Abstract
BACKGROUND
Endoscopic transanal resection (ETAR) is a scarcely used technique to treat large or sessile rectal adenomas not amenable to polypectomy. The purpose of this study was to evaluate safety and long-term results of ETAR in treating rectal adenomas in three hospitals over 15 years.
METHODS
Patients who underwent ETAR during 1996-2010 were retrospectively analyzed with respect to patient, adenoma, and operative characteristics, earlier operations, complications, follow-up time, recurrence rates, recurrence treatment, and cancer incidence.
RESULTS
Ninety-two patients underwent a total 111 ETARs to treat rectal adenoma. The mean age of patients was 71 years, and the median ASA class 3. Twenty-eight patients previously had received other treatments for rectal adenoma. Incidental carcinoma was found in eight patients. Sixty-seven adenomas were treated with only one ETAR and 17 with two or three ETARs. Sixty-seven patients did not have a recurrence, whereas 14 patients had an adenoma recurrence and 3 patients developed invasive carcinoma during a mean follow-up of 30 months. Complications occurred in 14 patients; all were minor, except for one explorative laparotomy without findings. No mortalities or conversions to open surgery occurred.
CONCLUSIONS
ETAR is a minimally invasive and safe technique with inexpensive instrumentation to treat rectal adenomas that are not amenable to polypectomy. Adenoma recurrence rate was 15% and cancer incidence 3% in follow-up.
