Advantage of cold snare resection for anticoagulant therapy in patients with small colonic polyps / 中国内镜杂志

ABSTRACT

Objective To study the safety of cold snare in colon polyps of anticoagulant patients. Finding a safe and convenient way to remove small polyps in the colon in patients receiving anticoagulant therapy. Methods In our hospital outpatient and inpatient colonoscopy findings of colonic polyps (3 ～ 8 mm diameter) of the 60 patients received anticongulation treatment as the research object, randomly divided into cold trap group and high frequency electrocoagulation group, 30 cases in each, using cold trap technology, high frequency electrocoagulation technology excision of polyps respectively. Comparison of the two groups of patients with polyp location, size, quantity, resection time, intraoperative and postoperative bleeding rate, the rate of complete resection of colonic polyps, sample recovery rate, pathological examination results and pathological specimens in submucosal arteriole injury. Results The average age of the two groups was (46.76 ± 8.52) years, gender, colonoscopy indication, bowel preparation score and ileal intubation success rate differences has no significant difference (P > 0.05), comparable; cold trap group polyps operation time (3.26 ± 0.84) min, the high frequency electrocoagulation group (5.17 ± 1.25) min, the difference between the two groups was significant (P < 0.05); cold trap group polyp complete resection rate was 100.00％ (57/57), high frequency electrocoagulation group was 88.68％ (47/53), the two groups had significant difference (P < 0.05); the average number of the two groups of patients with polyps, polyp diameter, the location, intraoperative bleeding, postoperative bleeding and polyps from two weeks of recovery rate showed no significant difference (P > 0.05); the two groups of patients with pathological type and specific differences had no statistically significance (P > 0.05); cold trap group specimens of stick there was no damage in the arteriole of the submucosa, and 7 cases in the high-frequency electrocoagulation group were impaired, and the difference between the two groups was significant (P < 0.05). Conclusion For the resection of anticoagulation for patients with high frequency, electric coagulation and cold trap compared to traditional small polyps excised colon has more secure, convenient and accurate pathological and other advantages, but limited to the single center, low sample size conditions, cold trap technology by therapeutic effect and advantages of anticoagulant therapy in patients still need to be further studied.
