[目的]总结直肠类癌超声内镜下影像特征,探讨内镜下微创治疗的安全性及疗效。[方法]分析29例直肠类癌超声内镜下影像特征,8例患者行内镜黏膜下剥离术,观察并发症和术后复发情况。[结果]8例患者行内镜黏膜下剥离术,手术时间平均50min(35～85min),术后随访1年无一例复发转移。[结论]类癌在超声内镜下有其特征性表现,内镜黏膜下剥离术治疗直肠类癌安全,但远期效果有待进一步研究。
[Objective] To summarize the characteristics of endoscopic ultrasonography of rectal carcinoid and explore the safety and efficacy of endoscopic minimally invasive treatment. [Methods] The imaging features of 29 cases of rectal carcinoids were analyzed by endoscopic ultrasonography. 8 cases underwent endoscopic submucosal dissection. The complication and postoperative recurrence were observed. [Result] The endoscopic submucosal dissection was performed in 8 patients. The average operation time was 50min (35-85min). No recurrence and metastasis was observed in one year follow-up. [Conclusion] Carcinoid carcinomas have their characteristic manifestations under endoscopic ultrasonography. Endoscopic submucosal dissection is safe for treatment of rectal carcinoid tumors, but the long-term effect needs further study.
