摘　　要：目的 探讨超声微探头辅助内镜下切除大肠巨大良性广基息肉的方法.方法 病例来源于我院经结肠镜检查直径在2cm以上的大肠巨大广基息肉45例,病理检查均为腺瘤性息肉.完善术前检查并清洁肠道,常规插入结肠镜至病变部位,完全暴露息肉后,用超声微探头扫描确定息肉基底,后用注射针于病变基底部注射生理盐水,病变隆起后用圈套器套取,采用分块多次切除法将息肉切除.结果 45例患者巨大息肉经分块多次切除,均完全切除,术中术后均未发生大出血及穿孔,3～6个月内复查结肠镜残端愈合良好.结论 结肠良性巨大广基息肉用超声微探头辅助,经肠镜分次切除治疗效果好.Objective To evaluate the ultrasonic microprobe assisted endoscopic resection of large polyps in co- lon. Methods 45 Cases with large sessile colon polyps underwent colonoscopy, all polyps were more than 2cm in di- mneter, pathological diagnosis were adenomatous polyps. When the polyps were completely exposed, ultrasonic micro- probe were used to determine the polyp＇s base. After submucosal injection of epinephrine at the base of polyp, either en bloc or piecemeal snare polypectomy were performed. All resected specimens were retrieved for pathologic study. Re- sults All 45 cases were completely removed, no complication occurred. Resection site were well healed in 3 and 6 months follow - up. Conclusion Ultrasonic microprobe assisted endoscopic resection of large sessile polyps in colon is a safe and effective procedure. There is high value of clinical promotion.
