%X In tracheobronchomalacia, the structural weakening of the airway results in altered ventilatory mechanics. This case report describes a patient with known tracheobronchomalacia who experienced expiratory central airway collapse and dynamic pulmonary hyperinflation during peroral endoscopic myotomy (POEM) to treat symptomatic achalasia. We discuss the physiological considerations and potential complications of a POEM procedure with superimposed tracheobronchomalacia and present perioperative strategies for the prevention and management of this potentially deleterious combination. Although tracheobronchomalacia was a known condition in our patient, it is likely an underdiagnosed condition that may first present intraoperatively.
