Background: Endoscopic mucosal resection (EMR) of early superficial colorectal carcinomas is nowadays accepted as the gold standard treatment for this type of neoplasia.
Aim: This study aims to evaluate the efficacy and safety of mucosectomy in elderly patients considering the predictive value of submucosal infiltration.
Methods: A retrospective study of all patients referred for EMR of sessile colorectal polyps classified IIa by the Paris classification between April 2013 and April 2015. A total of 50 patients (30 males (60 %); age range = 44-86; mean age = 67.7) were enrolled. Patients were divided in two groups considering 65 years as cutoff to individuate the elderly patients.
Results: EMR was performed in 53 lesions: 39 were performed en bloc and 14 by piecemeal technique. 30 % of lesions were in the rectum; 11 % in the sigmoid colon; 15 % in the descending colon; 6 % in the transverse colon; 24 % in the ascendant colon; and 14 % in the cecum. The mean size of the resected specimens was 20 mm (range 8-80 mm). The rate of complete resection was 79.2 %, incomplete 13.2 %, not estimable 7 %. Ten patients underwent surgery because of an incomplete resection and/or histological evaluation.
Conclusions: Colon EMR is safe and effective in elderly patients. Endoscopy is still helped in the correct indication for surgery in high-risk surgical patients.
