BACKGROUND AND AIMS: This study reviewed the outcome of endoscopic transanal resection (ETAR) for the treatment of patients with villous rectal adenomas (VRA).PATIENTS AND METHODS: This study included 28 consecutive patients who underwent ETAR for VRA between October 1992 and December 2000. All tumors were believed to be benign (clinical examination, endorectal ultrasonography, multiples biopsies) A retrospective evaluation of the outcome of ETAR was performed.RESULTS: Thirteen patients (46.4%) had a large VRA with a tumor length of more than 5 cm. The tumor involved the anterior rectal wall in ten cases. Ten patients (35.7%) required more than one procedure. Median operating time was 35 min (range 20-50). Morbidity was 5% ( n=2); no patient died. Median postoperative stay was 3 days (range 1-5). Three patients (9.3%) were confirmed on histology as having adenocarcinoma of the rectum and underwent a conventional surgical procedure. At a median follow-up of 5 years (2.5-10.5), two recurrences were noted.CONCLUSION: Our data suggest that the technique of transanal resection has a limited but valuable place in rectal surgery. ETAR is a simple, minimally invasive, and economical method for treatment of patient with VRA. ETAR should be performed in collaboration with an experienced urological endoscopist. ETAR is a useful addition to the surgeon's armamentarium together with laser destruction and transanal endoscopic microsurgery.
