Characteristics of thoracoscopic anatomical lesion resection in the treatment of intralobar sequestration and congenital pulmonary airway malformation.

OBJECTIVE

Intralobar sequestration (ILS) and congenital pulmonary airway malformation (CPAM) each have their own characteristics. Therefore, there are also differences in the implementation of HuaXi-thoracoscopic anatomical lesion resection (HX-TALR). This study aims to summarize the characteristics of HX-TALR in treating ILS and CPAM.

METHODS

A retrospective review of clinical data was conducted for patients who underwent HX-TALR in our hospital from October 2019 to October 2024.

RESULTS

There were 612 patients in this study, including 158 patients with ILS and 454 patients with CPAM. The completion rate of HX-TALR in the ILS group (158/158 100%) was higher than that in the CPAM group (355/454, 78.2%). Compared with the CPAM group, the ILS group had a significantly lower average age (7.98 vs 9.13 m), mean lesion diameter (4.08 vs 4.28 cm), average operation time (61.41 vs 67.89 min), average intraoperative bleeding volume (11.99 vs 14.12 ml), and drainage tube placement time (1.17 vs 1.31 days). The proportion of single cysts with a diameter > 2 cm in the ILS group was lower than that in the CPAM group (16.46% vs 63.22%), whereas the proportion of single cysts with a diameter < 2 cm in the ILS group was significantly greater than that in the CPAM group (83.54% vs 36.78%).

CONCLUSION

HX-TALR treatment for ILS is widely applicable. The clear internal and external boundaries of the ILS make it easier to perform HX-TALR and can be selected as an early-stage case. With increasing experience, the completion rate of HX-TALR in the treatment of CPAM will also increase.
