Background And Aims:
To overcome the technical difficulties associated with gastric endoscopic submucosal dissection (ESD), a novel traction device that can alter the direction of traction was developed. This study compared the efficacy and safety of conventional ESD versus those of traction-assisted gastric ESD.
Methods:
Patients with a single gastric epithelial neoplasm were randomized to receive conventional (n = 75) or traction-assisted (n = 73) gastric ESD. The primary outcome was ESD procedure time.
Results:
There were no differences between the conventional and traction-assisted groups with respect to treatment results or adverse events. The mean procedure time was similar for both groups (78.9 vs 88.3 minutes, respectively; P = .3); however, times for the traction device tended to be shorter for lesions in the lesser curvature of the upper or middle stomach (84.6 vs 123.2 minutes; P = .057).
Conclusions:
Traction-assisted ESD for lesions in the lesser curvature of the upper or middle stomach were shorter, thereby reducing the procedure time of conventional ESD. (Clinical trial registration: University Hospital Medial Information Network Clinical Trials Registry, identifier 000044450.).
