Abstract

Abstract: Purpose The aim of this study is to evaluate the safety and efficacy of endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) after R1 endoscopic resection or local recurrence of early rectal cancer after operative endoscopy.Material and methods Twenty patients with early rectal cancer were enrolled, including patients with incomplete endoscopic resection, or complete endoscopic resection of a tumor with unfavorable prognostic factors (group A, ten patients), and local recurrence after endoscopic removal (group B, ten patients). At admission, histology after endoscopic polypectomy was: TisR1(4), T1R0G3(1), T1R1(5) in group A, and TisR0(8), T1R0(2) in group B. All patients underwent ELRR by TEM with nucleotide-guided mesorectal excision (NGME).Results Mean operative time was 150 minutes. Complications occurred in two patients (10%). Definitive histology was: moderate dysplasia(4), pT0N0(3), pTisN0(5), pT1N0(6), pT2N0(2). Mean number of lymph-nodes was 3.1. Mean follow-up was 79.5 months. All patients are alive and disease-free.Conclusions ELRR by TEM after R1 endoscopic resection of early rectal cancer or for local recurrence after operative endoscopy is safe and effective. It may be considered as a diagnostic procedure, as well as a curative treatment option, instead of a more invasive TME.
