Abstract:
Objective:To compare the efficiency and safety of T knife and Dual knife in endoscopic submucosal dissection (ESD) in the treatment of esophageal lesios.Methods:A total of 59 hospitalized patients with esophageal lesions who underwent ESD in the First Affiliated Hospital of Soochow University from June 2018 to January 2019 were enrolled in the study, and the patients were randomly divided into T knife group ( n=29) and Dual knife group ( n=30). The operation time, resection speed, complete resection rate, and complications of the two groups were compared. Results:There were no significant differences in gender, age and comorbidity between the T knife group and the Dual knife group (all P > 0.05). The operation time of T knife group and Dual knife group was 57.86±24.62 min and 66.28±29.48 min, respectively, and the difference was statistically significant ( t=1.189, P=0.024). The resection speed of the two groups was 22.80±7.31 mm 2/min and 16.20±7.24 mm 2/min, respectively, with significant difference ( t=3.484, P=0.001). The complete resection rate of the two group was 86.2% (25/29) and 86.7% (26/30), respectively, with no significant difference ( χ2 =0.108, P=0.742). There were 2 (6.9%) cases of complications in the T knife group, while 5 (16.7%) cases in the Dual knife group, the incidence of complications was no significant difference ( χ2=0.574, P=0.449). There was no perforation or bleeding in the both groups. Conclusion:In the treatment of esophageal lesions, T knife in ESD has the advantages of short operation time and high resection speed compared with Dual knife, and is worthy of clinical application.
