# Progress in the Application of Bronchoscopic Cryotherapy in Pediatric Pulmonary Diseases

## TL;DR

Bronchoscopic cryotherapy is a new treatment for children's lung diseases, offering safe and effective relief for airway blockages.

## Contribution

This paper reviews the progress and safety of cryotherapy in pediatric pulmonary diseases.

## Key findings

- Cryotherapy via flexible bronchoscopy is safe and feasible in children.
- It is mainly used for airway obstructive diseases caused by benign conditions.
- Long-term complications require careful consideration in pediatric applications.

## Abstract

Cryotherapy in interventional bronchoscopy is a new treatment modality which has recently been made available for the pediatric airway. Lack of experience and safety concerns have led to hesitant adaptation. The aim of this work was to elaborate on the application progress of cryotherapy in pediatric pulmonary diseases and also to assess indications, success rates, and complications of airway cryotherapy in children. In summary, cryotherapy via flexible bronchoscopy is a safe and feasible method. The application scope in pediatrics is similar to that in adults, and it is mainly used in airway obstructive diseases. However, it is primarily caused by benign conditions, and the interventional treatment mainly seeks to provide long-lasting symptomatic alleviation. Thus, prevention, treatment, and prognosis of long-term complications are issues that should be carefully considered in pediatric applications.
