Use of extracorporeal membrane oxygenation during resection of recurrent laryngeal papillomatosis: A case report

Recurrent laryngeal papillomatosis (RLP) is a common benign tumor in the larynx of children, which is characterized by high recurrence rate and rapid growth, leading to clinical symptoms such as hoarseness and difficulty breathing. Low-temperature plasma radiofrequency ablation (RFA) is the main treatment, but ventilation problems are often encountered during surgery. PATIENT CONCERNS: We report a case of a 2-year-old child with RLP who underwent low-temperature plasma RFA with the assistance of a laryngoscope. However, the surgery had to be temporarily stopped due to ventilation difficulties and difficulty in maintaining blood oxygen saturation during the procedure. DIAGNOSIS: The child was diagnosed with RLP. INTERVENTIONS: The child underwent low-temperature plasma RFA supported by laryngoscopy assisted by ECMO. OUTCOMES: Despite ventilation problems during surgery, the use of ECMO support helped maintain good oxygen saturation in the child and provided a clear surgical field, enabling the tumor to be quickly and cleanly removed. Therefore, the use of ECMO provided critical support during the surgery. LESSONS: This case highlights the importance of airway management during laryngeal papillomatosis surgery. A thorough airway assessment should be performed before anesthesia, and early use of ECMO can reduce harm to the child and ensure the child’s safety.
