Absorbable Clips Applied in Thoracoscopic Anatomical Lung Resection in Younger Children: A Retrospective Study

Abstract

Abstract Objectives: This study aims to evaluate the feasibility and safety of a 5-mm absorbable clips applied in Thoracoscopic anatomical lung resection in younger children. Methods: Demographic data and intra- and postoperative parameters of the two groups (Abs-o-lock group and Hem-o-lok group) were reviewed. In the Abs-o-lock group, 5-mm absorbable clips were used in TALR on all patients from January 2020 to March 2021. In the Hem-o-lok group, 5-mm Hem-o-lok clips were used from January to December 2019. The primary outcomes were the one-time success rate of ligation, major bleeding rate, conversion rate, dislodgement rate and operative time, which were compared between the two groups. Results: There were 224 patients involved in this study, of whom 103 were in the Abs-o-lock group and 121 were in the Hem-o-lok group. The one-time success rate of ligation was 96.5% in the Abs-o-lock group and 98.9% in the Hem-o-lok group (p<0.05). No major bleeding occurred in either group. The conversion rates of the two groups were not significantly different (0/103 versus 2/121, p=0.55). The dislodgement rate did not significantly differ between the two groups (p=1.0). The operative time consumed in the Abs-o-lock group was much longer than that in the Hem-o-lok group in terms of subgroups of RES (resection of extralobar sequestration, p<0.05), lobectomy (p<0.05) and segmentectomy (p<0.05). Conclusions: Compared to Hem-o-lok clips, it is feasible and safe to apply 5-mm absorbable clips for vessel sealing during thoracoscopic anatomical lung resection in younger children.
