Endoscopic mucosal resection for rectal carcinoid tumors / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.
