Thoracoscopic versus open resection for symptomatic congenital cystic
adenomatoid malformations of the lung in neonates: a decade of
experience
Abstract
Purpose: The purpose of this study is to present our surgical experience
with symptomatic congenital cystic adenomatoid malformations (CCAMs) in
neonates. Methods: The medical records of neonates who underwent surgery
for symptomatic CCAM from 2010 to 2020 were retrospectively reviewed.
Results: Of 24 cases, 10 involved open resection, and 14 involved
thoracoscopic resection. Four cases of CCAMs located in the upper or
middle lobes underwent lobectomy, and 20 cases underwent lung-preserving
wedge resection in the lower lobe. Between the two groups, there was no
statistically significant difference in related preoperative variables,
including gestational age at birth, body weight, head circumference,
lesion size, CVR, and age at operation (P>.05). The
differences in intraoperative variables were statistically significant.
The length of the surgical incision in the thoracoscopic resection group
was significantly shorter than that in the open resection group (1.4 cm
[1.3-1.8] vs 6.0 cm [5.0-8.0], P=.000), and there was
significantly less operative blood loss (3 ml [1-6] vs 5 ml
[2-10], P=.030), but the operation time was significantly longer
(159 min [100-220] vs 110 min [70-170], P=.003). Regarding
postoperative variables, ventilator days, duration of chest tube use and
length of hospital stay were not statistically significant
(P>.05). Conclusions: Thoracoscopic resection is a safe and
favorable approach for symptomatic CCAM in neonates. It has minimal
esthetic effects and does not increase the risk of surgical or
postoperative complications. Lung-preserving resection is feasible for
neonatal CCAM surgery.
