Surgical Management of Pleural Complications in Lymphangioleiomyomatosis

Abstract

ObjectiveLymphangioleiomyomatosis (LAM) is a rare cystic lung disease occurring primarily in women. Pneumothorax and chylothorax are common pleural complications in LAM. We aim to explore various options in the surgical management of pleural disease in LAM. MethodsA retrospective chart review of all patients at the Center for LAM and Rare Lung Diseases at Columbia University was performed, and date, type and indication for surgical procedure were collected. All patients with any cystic lung disease seen between January 1, 2000 and March 1, 2023 were included in the database. ResultsThe charts for 326 patients with possible LAM were reviewed, including 213 with confirmed LAM and 113 females with cystic lung disease consistent suspected to be LAM were reviewed. 40.5% underwent surgical procedures at our institution or at referring hospitals. 15.6% of patients underwent surgical lung biopsies. 16.6% had a history of pneumothoraces, of which 79.6% underwent chemical and/or mechanical pleurodesis, 14.8% required pleurectomy, and 7.4% were discharged with tunneled indwelling pleural catheters (IPC). 5.6% of confirmed LAM patients have history of chylothorax, with thoracic duct ligation, thoracic duct embolization, pleurodesis, and pleurodesis with long-term tunneled IPC placement all used as treatment strategies. ConclusionsHere we demonstrate the significant burden of pleural disease in patients with LAM. It is imperative that thoracic surgeons understand the high incidence of pneumothorax in this patient population. Tunneled IPCs are underutilized but provide long term options for chylous management with long term mechanical pleurodesis and a decrease in hospital length of stay.
