Abstract:
Objective To evaluate the clinical value of endoscopic ultrasonography (EUS) in diagnosis and treatment of rectal carcinoid tumom, and the safety and efficacy of endoscopic submucosal dissection (ESD) for rectal carcinoid tumors. Methods All the submucous tumor considered rectal carcinoid tumor received EUS examination and according to the result to select appropriate therapeutic regimen. Results All the 45 lesions were verified rectal carcinoid tumors by pathological examination. 42 patients received endoscopic submucosal dissection. Two tumors invaded into the muscularis propria and one tumor invaded beyond serosa and with lymph node metastasis received surgical strategy. Conclusion EUS can be used to determine surgical strategy for rectal carcinoid tumor for it provides precise information of the size, depth, border, muscularis propria or vessel infiltration of the tumor. For rectal carcinoid tumors smaller than 20 mm in diameter, ESD is safe and effective.
