A Clinical Study Of Endoscopic Biopsy Forceps Polypectomy And Hot Snare Polypectomy For Colorectal Micro-polyps

Objective:To explore the efficacy and safety of endoscopic cold biopsy forceps and hot snare polyps for colorectal micropolyps(≤5mm).Method:A retrospective analysis of patients with colorectal micropolyps treated in the Department of Gastroenterology,the First Affiliated Hospital of Xinjiang Medical University from May 2018 to May 2019 was divided into a biopsy forceps removal group and a snare thermal excision group,and the two surgical methods were compared The incidence of complications,length of stay,length of stay,and recurrence rate at 6 months after surgery.Results:A total of 109 patients were included in the study,55 in the biopsy forceps removal group and 54 in the snare thermal resection group.Postoperative perforation rates were 0 in the biopsy forceps group and the snare group;the postoperative delayed bleeding rates were 0 and 2(3.9%),respectively,with no significant difference(P>0.05);postoperative abdominal distension The incidence was 0 and 5 cases(9.3%).The incidence of abdominal distension was lower after cold resection with biopsy forceps,and the difference was statistically significant(P<0.05).The recurrence of biopsy forceps in group 1 was reexamined in 6 months after surgery For example,there were 2 cases in the snare thermal resection group,but none of them recurred in situ,and the difference in recurrence rate was not statistically significant(P>0.05).The average length of hospital stay in the biopsy clamp group was 1.29 ±0.74 days,and the hospitalization cost was 3144.48±215.19 yuan.the average length of hospital stay in the snare thermal resection group was 2.11 ± 2.05 days,and the hospitalization cost was 5028.375 ± 1428.79 yuan.There was a statistically significant difference in hospitalization days and hospitalization costs between the two groups(P<0.05).Adenomatous polyps are the predominant pathological properties of colorectal micropolyps.Tubulous adenomas are the most common type of adenomatous polyps,and inflammatory polyps are the most common type of nonadenomatous polyps.Colorectal micropolyps of >3mm are more likely to be adenomatous,and ≤3mm are mostlynon-adenomatous polyps.Conclusion:Colorectal micropolyps cold biopsy polypectomy can effectively remove colorectal micropolyps compared with hot snare polypectomy,but cold biopsy forceps are safer,and the incidence of postoperative abdominal distension complications is relatively small,Hospital stay days and hospital costs are lower;The pathological nature of postoperative adenomatous polyps was mainly tubular adenomas with a diameter of more than 3mm,and non-adenomatous polyps were mainly inflammatory polyps with a diameter of ≤3mm.Recurrence is still possible after colorectal polypectomy,and regular follow-up colonoscopy is required.
