3.1 Patient population and characteristics
Of the 24 patients, 14 were male and 10 were female. Twenty-three
patients were diagnosed with prenatal sonography. The most common
respiratory symptoms were pneumonia, respiratory distress and shortness
of breath. All of the patients had suffered from neonatal pneumonia; two
patients had pneumonia with respiratory distress, and eight had
pneumonia with shortness of breath. Two patients had mediastinal
deviation due to large lung lesions. Four patients with CCAM located in
the upper or middle lobes underwent lobectomy, and 20 underwent
lung-preserving wedge resection in the lower lobe, regardless of whether
the lesion was on the left or right side. The final pathological result
was 20 cases of CCAM and 4 cases of CCAM with PS. One patient was found
to have congenital chylothorax after the operation and healed after
sufficient drainage. One patient had postoperative complications of a
air leaks and healed spontaneously after conservative treatment. Details
of the patient population and the characteristics of the thoracoscopic
resection and open resection groups are shown in Table 1. Some variables
were statistically analyzed, and there was no statistically significant
difference between the two groups.
The median follow-up time was 25 months (range, 1-47 months), and none
of the patients experienced postoperative recurrence, shortness of
breath, difficulty breathing after activity, or repeated pneumonia. One
patient who was treated with open resection had a slightly sunken chest
while breathing.
