Treatment of colorectal polyps by nylon ligation combined with endoscopic high-frequency electric snare / 中华消化外科杂志

ABSTRACT

ObjectiveTo evaluate the clinical efficacy and safety of nylon ligation combined with endoscopic high-frequency electric snare for the treatment of colorectal polyps.MethodsThe clinical data of 345 patients with colorectal polyps who received the treatment of nylon ligation combined with endoscopic high-frequency electric snare at the Zhongshan Hospital of Fudan University from January 2006 to January 2011 were retrospectively analyzed.Complications including bleeding and perforation were observed.Postoperative wound healing and local residual recurrence were assessed during follow-up.ResultsA total of 362 colorectal polyps were successfully removed.The mean diameter of the colorectal polyps was 2.7 cm (range,1.5-4.0 cm). Operative bleeding occurred in 1 patient,and perforation in 1 patient.The results of histological examination showed that 93.6％(339/362) colorectal polyps were adenoma,17 were hyperplastic polyps,5 were inflammatory polyps,and caneeration of colorectal polyps in 1 patient was detected.Endoscopic follow-up was completed in 334 patients at the first month after operation,and 9 patients with residual benign colorectal polyps received endoscopic resection.No residue or recurrence was found in the other patients.Endoscopic follow-up was completed in 308 patients at the second months after operation,and no residue or recurrence was found.The overall effective rate was 97.1％ (299/308).ConclusionEndoscopic nylon ligation combined with endoscopic high-frequency electric snare is effective and safe for the treatment of colorectal polyps.
