This retrospective cohort study analyzed the evolving etiology, clinical characteristics, perioperative outcomes, and long-term prognosis of pediatric necrotizing pneumonia (NP). Data were collected for children diagnosed with NP between January 2017 and June 2025. The report focuses on the subgroup who required surgical intervention after failure of medical therapy.
A total of 398 children with NP were included in the study period. Of these, 42 children (10.55%) underwent surgical intervention due to failed conservative treatment or development of complications necessitating operation. Pathogens were identified in 95.2% of surgically treated cases. The most common identified pathogen was Mycoplasma pneumoniae, accounting for 52.50% of detections among the surgical cohort. The authors highlight this predominance as an update to the disease’s etiology and recommend attention to atypical pathogen testing in clinical practice.
Preoperative complications were present in 83.33% of patients who proceeded to surgery, indicating a high burden of comorbidity and local complications at the time of operative decision-making. The study frames surgery as a timely, individualized intervention reserved for cases in which medical therapy failed or specific complications developed; detailed criteria for surgical indication beyond failure of medical therapy were not reported in the abstract.
Reported perioperative metrics for the surgical group include a mean operative time of 140.71 ± 49.84 minutes and mean intraoperative blood loss of 119.79 ± 49.97 mL. Mean chest tube duration after surgery was 7.83 ± 3.05 days, and mean postoperative hospital stay was 14.74 ± 3.53 days. These values summarize the immediate operative and recovery course for children undergoing surgical management of NP in this cohort.
Patients who underwent parenchymal resection were compared with those who received non-resection surgical approaches. The parenchymal resection group had a significantly longer operative time (P < 0.001) and greater intraoperative blood loss (P < 0.05). No significant differences were observed between these groups in drainage duration or overall length of hospital stay (P > 0.05). The abstract does not provide subgroup counts or additional stratified outcome measures beyond these comparisons.
Five postoperative pulmonary adverse events were recorded in the surgical cohort. All five events resolved completely with conservative (non-surgical) management. No postoperative mortality was reported in the cohort. The abstract does not specify the exact nature of these pulmonary adverse events or the conservative treatments used.
Patients were followed for a median of 64.4 months, with a reported range of 5 to 101 months. During this follow-up interval, there were no recurrences of necrotizing pneumonia and no deaths reported among the surgically treated patients. The authors present these findings as evidence of excellent long-term recovery after timely surgical intervention, including lung resection when clinically required.
In this single-cohort retrospective series, timely and individualized surgical intervention for pediatric NP—up to and including parenchymal resection—was associated with manageable perioperative courses, a low rate of persistent postoperative adverse outcomes, and excellent long-term prognosis with no recurrences or mortality observed during extended follow-up. The high detection rate of pathogens and predominance of Mycoplasma pneumoniae underscore the importance of routine testing for atypical organisms in children with severe or complicated pneumonia. These findings provide clinical evidence to inform surgical decision-making in pediatric NP when medical therapy fails, although detailed operative indications and intraoperative decision pathways are not reported in the abstract.
The study was approved by the Ethics Committee of the Children’s Hospital of Nanjing Medical University (No. 202510017–1) and was conducted according to the Declaration of Helsinki. Written informed consent was obtained from the parent or legal guardian of each participant. The authors declared no competing interests.
