Abstract:
Objective To investigate the application effect of postural gravity traction combined with floss and titanium clip pulley external traction in endoscopic submucosal dissection(ESD)for early intestinal lesions.Methods A total of 100 patients with early colorectal lesions admitted to the Affiliated Hospital of Jiangsu University from January 2022 to September 2024 were selected as the research subjects and divided in-to the observation group and the control group,with 50 cases in each group.The control group underwent con-ventional intestinal ESD treatment,while the observation group used positional gravity traction combined with dental floss and titanium clips to form pulley external traction in ESD treatment.Clinical data including opera-tion time,number of submucosal injections,intraoperative blood loss,lesion resection effect,complication inci-dence,and hospital stay were compared between the two groups.Results The total operation time in the ob-servation group was shorter than that in the control group,and the total number of submucosal injections was less than that in the control group,with statistically significant differences(P<0.05).There were no signifi-cant differences in intraoperative blood loss,complete resection rate,complication incidence,en bloc resection rate,and hospital stay between the two groups(P>0.05).For lesions≤1 cm or>5 cm in size,there were no significant differences in operation time,complete resection rate and en bloc resection rate between the two groups(P>0.05).For lesions>1-3 cm or>3-5 cm in size and laterally spreading lesions,significant differences were observed in operation time,number of submucosal injections,complete resection rate,and en bloc resection rate between the two groups(P<0.05).For pedunculated polyps,there were no significant differences in the number of submucosal injections,complete resection rate and en bloc resection rate between the two groups(P>0.05),but the operation time differed significantly(P<0.05).Conclusion Postural gravity traction combined with dental floss and titanium clip to form pulley external traction is simple to oper-ate in ESD for early intestinal lesions.It can maintain a clear field of view,shorten operation time,reduce the incidence of complications,and is safe and effective.
