INTRODUCTION: The incidence of rectal carcinoid tumors is increasing due to the widespread use of screening colonoscopy. Endoscopic mucosal resection (EMR) is a useful method for small rectal carcinoid tumors (≤10mm) because of its simplicity, quick procedure and low complication rates. We aimed to describe our experience and evaluate the outcomes of EMR for rectal carcinoid tumors.
METHODS AND PROCEDURES: The patients enrolled in this study were 13 patients with small rectal carcinoid tumors who underwent EMR using a submucosal injection technique of epinephrine-saline mixture between August 2010 and October 2016. All medical records, including characteristics of the patients and tumors, complications, were retrospectively reviewed.
RESULTS: The patients were 6 men and 7 women, with a mean age of 40.8 years (range, 21-72 years). En block resection was performed by EMR in all cases. The endoscopic mean size of tumors was 6.46 mm (range, 5-10 mm). The pathologically measured mean size of the resected specimens was 5.92 mm (range, 4-10 mm). The mean size of resected carcinoid tumors was 4.33 mm (range, 1.8-7 mm). The tumor shape was submucosal tumor in 10 and polyp in 3. Histological examination revealed that 5 cases had resection margin positive of tumor and 1 case had undetermined resection margin of tumor. Of the 6 patients, 4 patients underwent endoscopic treatment and 2 patients underwent transanal excision. No residual tumor was found in additionally removed tissue. There were 2 cases with EMR-related complications: 1 early postprocedural bleeding and 1 postpolypectomy syndrome. There was no significant bleeding requiring blood transfusion or perforations.
CONCLUSION: Endoscopic mucosal resection is considered to be a relatively safe and useful method for treatment of small rectal carcinoids in selected patients.
