Abstract:
Objective To investigate the endoscopic and ultrasonic endoscopic features of colorectal carcinoid and the indications of endoscopic treatment. Methods The clinical data of 22 patients with colorectal carcinoid who had been admitted to our hospital from 2002 to 2007 were collected. The endoscopic and ultrasonic endoscopic features and the relationship between the features and invasion depth of colorectal carcinoid were analyzed. Results Under the endoscope, early carcinoid presented submucosa tumor with 1.5cm in diameter, and yellow or white smooth surface; advanced carcinoid presented submucosa tumor with 0.8-3.0cm in diameter, and yellow or white little nodus or ulcerative surface. The ultrasonic endoscopic feature of the colorectal carcinoid was orbicular-ovate low level echo tumor with punctiform slightly high-level echo and an unsharpness edge. Sixteen mucosal layer-cancers and submucosal layer-cancers were removed by endoscopic mucosal resection, and 10 of them were additional treated by argon plasma coagulation. After a follow-up period of 4-36 months, no recurrence was observed. Conclusions Endoscopy and endoscopic ultrasonography are effective methods to diagnose colorectal carcinoid and its invasion depth. Endoscopic treatment is a simple, safe and effective means to treat the early colorectal carcinoid tumors.
