Abstract:
Objective:To explore the effect of cold-strap endoscopic mucosal resection (CS-EMR) in patients with colorectal polyps.Methods:A prospective randomized clinical trial was conducted to 320 selected patients with colorectal polyps diagnosed by Shenzhen Luohu District People′s Hospital from May 2019 to June 2021. The patients were randomly divided into CS-EMR group and HS-EMR group with 160 cases each, using a random number table generated by Excel 2007. The main parameters for statistical analysis contain the process indicators of the two groups of surgical methods, the complete polypectomy rate of patients after surgery, the degree of postoperative pain and the recovery of gastrointestinal function, and the differences in surgical complications.Results:The polypectomy time of CS-EMR group was shorter than that of HS-EMR group: (4.11 ± 1.20) min vs. (4.42 ± 0.98) min, with a statistically significant difference ( P<0.05). The score of visual analogue pain scale (VAS) in CS-EMR group was lower than that in HS-EMR group at 4 and 12 hours after operation: (3.11 ± 0.78) scores vs. (3.48 ± 0.80) scores, (3.38 ± 0.80) scores vs. (3.61 ± 0.92) scores, with a statistically significant difference ( P<0.05). The first anal exhaust time and first defecation time in CS-EMR group were lower than those in HS-EMR group: (27.83 ± 5.01) h vs. (29.66 ± 4.84) h, (43.73 ± 7.80) h vs. (47.28 ± 8.14) h, with a statistically significant difference ( P<0.05). The complications in CS-EMR group were significantly lower than those in HS-EMR group: 5.63% (9/160) vs. 12.50% (20/160), with a statistically significant difference ( P<0.05). Conclusions:The effect of CS-EMR in the treatment of colorectal polyps is not different from that of HS-EMR, but the former has the advantages of short resection time, rapid recovery of gastrointestinal function after operation, light pain and less complications.
