摘要
目的肠镜下切除的结直肠息肉绝大多数为微小息肉(≤5 mm)或小息肉(6～10 mm),对于此类息肉的最佳切除方法目前缺乏统一指南。本研究旨在探究冷圈套息肉切除术联合黏膜下注射治疗结直肠息肉(直径≤10 mm)的可行性和有效性。方法本研究前瞻性随机选取2018年1月至2018年12月经解放军联勤保障部队第九〇〇医院消化内科行结肠镜检查发现结直肠息肉(直径≤10 mm)的300例患者进行对照研究,按1∶1随机分配接受冷圈套息肉切除术联合黏膜下注射(CSPI)或冷圈套息肉切除术(CSP)治疗。其中CSPI组在切除息肉之前先进行黏膜下注射,再行息肉切除,而CSP组则套取息肉后直接切除,然后在内镜窄带成像技术(NBI)引导下对息肉切除部位底部及侧切缘活检2～3块,用于病理组织学评估切除完整率。术中记录息肉切除时间、息肉回收情况和并发症。结果纳入研究的300例患者,CSPI组(n=150)和CSP组(n=150)病灶平均大小分别为7.7 mm和6.7 mm。患者的性别、年龄等及息肉部位、大小、形态、分型在组间均衡。CSPI与CSP相比完全切除率为96.7%vs 76.6%,差异具有统计学意义(P<0.001)。所有息肉均回收,其中9例CSP患者出现术中出血,CSPI组无术中出血,差异具有统计学意义(P<0.05);所有患者均无迟发性出血、穿孔等并发症。结论尽管CSPI较单纯采用冷圈套的治疗时间长,但却是一种安全、有效的息肉切除术,尤其对于6～10 mm息肉其全切除率高达98.9%,并且手术相关并发症发生率较低。
Objective The majority of polyps removed at colonoscopy are diminutive(≤5 mm)to small(6-10 mm)and there are few guidelines for the best way for these polyps to be removed.We aimed to assess the feasibility and effectiveness of cold snare polypectomy with injection(CSPI)for polyps≤10 mm.MethodsThis study prospectively and randomly selected 300 patients with colorectal polyps(diameter≤10 mm)found by colonoscopy in the gastroenterology department of 900 Hospital of the Joint Logistics Team from January 2018 to December 2018 for a control study,candidates were randomized(1∶1)to be treated with either cold snare polypectomy with injection(CSPI)or cold snare polypectomy(CSP).A small submucosal injection was administered prior to removal of the polyp using cold snare in the CSPI,whlie not in CSP.After polypectomy,an additional 2-3 forceps biopsies under narrow-band imaging(NBI)were performed at the base and margins of polypectomy sites to assess completeness of resection.Polypectomy timing,retrieval and complications were recorded at the time of the procedure.ResultsThree hundred patients were recruited with mean lesion size of polyps 7.7 mm in CSPI group(n=150)and 6.7 mm in CSP group(n=150).The patients′baseline characteristics and the location,size and shape of polyps removed were similar between the 2 groups.The complete resection rate(CRR)was respectively with CSPI and CSP 96.7%vs.76.6%,(P<0.001),there was significant difference between the two groups.Retrieval was completed for all polyps.Immediate bleeding during the procedure was more common in CSP has 9 cases,but no occurred in CSPI group(P<0.05),the difference was statistically significant,and there were no delayed bleeding or delayed perforation after polypectomy.ConclusionsCold snare polypectomy with injection is a safe and effective technique for polyps,with a high complete resection especially for 6-10 mm polyps reach to 98.9%,and low procedure-related adverse events,but the time taken for the procedure is greater than cold snare.
