目的探讨尼龙圈在结直肠粗蒂息肉经结肠镜高频电治疗中的临床疗效和安全性。方法将89枚息肉分为两组,其中研究组45枚,采用尼龙圈套扎联合高频电治疗,对照组44枚,单纯采用高频电治疗。观察两组息肉经内镜治疗后发生出血、穿孔等并发症的情况及息肉复发情况。结果两组患者89枚息肉均在内镜下成功切除,研究组未发生早期出血,对照组有6例患者并发早期出血,均经保守治疗治愈,研究组和对照组的早期出血率分别为0(0/45)和13.6%(6/44),两组间的差异有统计学意义(P=0.012)。所有患者均未见穿孔及迟发性出血,随访半年至3年,均未发现息肉复发。结论尼龙圈的应用对预防结直肠粗蒂息肉高频电切除后的早期出血有一定作用,增加了内镜下息肉切除的可能性和安全性。
Objective To investigate the clinical efficacy and safety of nylon ring in the treatment of colorectal polyp by colonoscopy. Methods Eighty-nine polyps were divided into two groups, of which 45 were study group. Nylon loop ligation combined with high-frequency electric therapy was used. In the control group, 44 were treated with high-frequency electric therapy alone. Observe the complications of bleeding, perforation and other complications of polyps after endoscopic treatment in both groups and the recurrence of polyps. Results 89 polyps in both groups were successfully resected under endoscopy. There was no early hemorrhage in the study group. Six patients in the control group complicated with early hemorrhage were cured by conservative treatment. The early hemorrhage rates in study group and control group were 0 (0/45) and 13.6% (6/44), respectively. The difference between the two groups was statistically significant (P = 0.012). All patients had no perforation and delayed bleeding, followed up for 6 months to 3 years, no recurrence of polyps were found. Conclusion The application of nylon ring can prevent early bleeding after colorectal polyp resection with high frequency and increase the possibility of endoscopic polypectomy and safety.
