Abstract:
Objective:To investigate whether prophylactic use of metal clips is necessary after cold snare polypectomy (CSP) of colorectal polyps of 6-10 mm.Methods:A total of 200 patients with 6-10 mm polyps that met the criteria of cold snare resection in Chengdu Third People's Hospital from 15 February 2022 to 30 May 2022 were randomly divided into two groups: a group that received preventive metal clip treatment and an observation group. Age, gender, body mass index (BMI), Boston score, endoscopy entry time, wound size, operation time, intraoperative bleeding time, postoperative delayed bleeding rate and cost between the two groups were compared and analyzed.Results:Ninety-eight patients in the metal clip group had 122 polyps removed, and 97 patients in the observation group had 119 polyps removed. There was no significant difference in the age, gender, BMI, Boston score, endoscopy entry time or wound size between the two groups. There were significant differences in the operation time (171.03±90.78 s VS 69.81±43.26 s, t=2.266， P=0.010), intraoperative bleeding time (19.98±17.37 s VS 29.16±17.56 s, t=-2.875， P=0.006) and surgery cost (571.63±110.92 yuan VS 366.32±13.2 yuan, t=18.102， P<0.001) between the metal clip group and the observation group. There was no significant difference in the delayed bleeding incidence［0.0%（0/98）VS 1.0%（1/97）， P=0.497］between the two groups. Conclusion:For patients with continuous bleeding time <60 seconds after CSP of 6-10 mm colonic polyps, the prophylactic use of metal clips may reduce the bleeding time, but may increase the operation time and cost. Metal clips have little effect on preventing postoperative complications.
