To Envaluate Endoscopic Diagnosis And Treatment Of Carcinoid Tumors

[Objective]To evaluate the safety and efficacy of endoscopic diagnosis and treatment of rectal carcinoid tumors.[Methods]The clinicial data of 30 patients with rectal carcinod tumors were analyzed retrospectively. Sixteen patients were diagnosed by endoscopic ultrasongraphy, and treated by endoscopic mucoal resecton (EMR).[Result]16 cases of rectal carcinoid tumors were resected by endoscopic submucosal resection.All the lesions were excised completely. The success rate was 100%. There were no immediate or late complications(bleeding and perforation.)after endoscopic submucosal resection. There was no local recurrence and no distant metastases in any patients during follow-up peroid of 3 months to 4 years.[Conclusions]EUS can provide precise information of rectal carcinoid about its size,depth, border, musculcaris propria and vessel infiltration. Endoscopic submucosal resection for the treatment-of small rectal carcinoid tumors less than or equal to 1.5cm in diameter is a simple, safe and effective therapeutic procedure.
