Postoperative recovery and bleeding risk after endoscopic snare cold resection in patients with 5-15 mm colorectal...

Endoscopic cold snare resection (CSP) can enhance postoperative recovery and minimize bleeding risk in patients with 5-15 mm colorectal polyps. However, more detailed evaluations are required to assess their advantages over conventional methods.

To evaluate the effects of endoscopic CSP on postoperative recovery and bleeding risk in patients with 5-15 mm colorectal polyps.

This randomized controlled study included 193 patients (mean age: 57.91 ± 5.41 years; 97 men and 96 women) with 5-15 mm colorectal polyps treated at Dongyang People's Hospital between March and June 2023. The patients were randomly assigned to the experimental group (n = 100), who underwent CSP, and the control group (n = 93), who underwent conventional endoscopic mucosal resection (EMR). Operation time, hospital stay, dietary status, and bleeding rate within 3 days were compared.

The CSP group had significantly shorter operation times (15.02 ± 2.44 minutes vs 18.78 ± 5.48 minutes, P < 0.001) and hospital stays (3.11 ± 1.08 days vs 4.89 ± 1.35 days, P < 0.001) than the EMR group. The fasting rate on the day of surgery was also lower in the CSP group (P < 0.05). The complete resection rates were similar between groups (98.00% vs 94.62%, P = 0.210), and no perforations occurred in either group. The 3-day postoperative bleeding rate was slightly lower in the CSP group (2.00%) than in the EMR group (6.45%), although this difference was not statistically significant (P = 0.234), indicating limited clinical relevance.

CSP was safe and efficient for removing 5-15 mm colorectal polyps, offering faster recovery and comparable safety to EMR. The procedural efficiency of CSP supports its broad clinical application.
