Absorbable Clips Applied in Thoracoscopic Anatomical Lung Resection in Younger Children.

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 thoracoscopic anatomical lung resection 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, intraoperative 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 intraoperative 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 for subgroups of 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.
