Objectives

Narrative objectives1

Colorectal endoscopic submucosal dissection (ESD) remains challenges, such as limited visualization and prolonged procedure time persist. Single-point traction enhances dissection efficiency, but has limitations, including diminished traction efficacy over time and the need for repositioning. We developed a novel multi-point traction device to provide stable and convergent traction. This study aimed to compare the efficacy and safety of non-traction, single-point traction, and multi-point traction for colorectal ESD.

Assessment

Primary outcomes

The primary outcome was the lesion resection speed, calculated as the resected area divided by the resection time.

Key secondary outcomes

Secondary outcomes included the overall procedure time, volume of injection per unit area, en bloc resection rate, R0 resection rate, and incidence of complications such as perforation and postoperative bleeding.

Other related information

Significant differences in each endpoint were analyzed among the three independent groups no traction, single-point traction, and multipoint traction. Among the endpoints, resection speed, resection time, and local injection drug use were proportionally scaled, and the Shapiro-Wilk test and the Kruskal-Wallis test were used to test normality and analysis of variance, respectively, for the three groups. The Bonferroni method was used for multiple comparisons for all endpoints. The p-values were tested at the two sided 5% significance level against the null hypothesis. There is no difference between the compared groups.
