金属钛夹预防内镜治疗结直肠大息肉的并发症研究

目的：探讨金属钛夹在内镜治疗结直肠大息肉中的并发症预防价值。方法：自2010年1月至2013年12月对80例直径大于2.0cm的结直肠息肉患者进行高频电凝电切术联合钛夹治疗。对于有蒂或亚蒂息肉先用钛夹钳夹蒂根部后进行经圈套高频电凝电切术;对于广基或者无蒂息肉先进行黏膜下注射,息肉隆起后行经圈套高频电凝电切术,再用钛夹封闭创面。结果：80例结直肠大息肉经圈套电凝电切联合金属夹治疗均一次性切除成功,所有治疗病例术中、术后未见出血及穿孔等并发症。结论：金属钛夹联合经圈套高频电凝电切术是治疗结直肠大息肉的一种操作简便、安全性高、疗效好的治疗方法,可有效预防出血、穿孔等并发症的发生。

Endoscopic Clips Combined with High-Frequency Electroresection Treament of Large Colorectal Polyps

Objective： To investigate the evaluation of endoscopic clips combined with high-frequency electroresection for large colorectal polyps. Methods： Totally 80 cases of large colorectal polyps removal was conducted by endoscopic clips combined with high- frequency electroresection from January 2010 to December 2013. For pedunculated polyps, clips were used to clamp the base of a polyp and then performed snare resection by coagulating and cutting with an electric current; For sessile polyps, after submucosal injection of an saline mixture, were resected and then wounds were closed with clips. Results： Combined with endoscopic clips, all the large colorectal polyps were snared and resected successfully by coagulating and cutting with high-frequency current.. No significant complication of bleeding and/or perforation occurred in all patients. Conclusions： Endoscopic clips combined with high-frequency electroresection is a simple, safe and effective method for large colorectal polyps removal, and can prevent the complication of bleeding and/or perforation from happening.
