内镜下对消化性息肉圈套电凝切除术时,往往因电凝不充分或机械性切割很容易造成术中即刻出血或术后迟发性出血等并发症。为了预防该并发症,我院对２１例２２枚消化性息肉,采用ＭＤ－８５０型和ＭＨ－８５８型金属夹钳夹与电凝切除联合应用,收到较好疗效。 Endoscopic electrocoagulation resection of digestive polyps, often due to inadequate coagulation or mechanical cutting is very easy to cause intraoperative bleeding or delayed postoperative bleeding and other complications. In order to prevent this complication, our hospital had 21 cases of 22 digestive polyps, using MD-850 type and MH-858 type metal clamp clamp and coagulation resection combined application, received good results.
