LAUSR

PurposeLung transplantation is accepted as an effective modality for patients with end-stage pulmonary lymphangioleiomyomatosis (LAM). Generally, bilateral lung transplantation is preferred to single lung transplantation (SLT) for LAM because of native lung-related complications, such as pneumothorax and chylothorax. It remains controversial whether SLT is a suitable surgical option for LAM. The objective of this study was to evaluate the morbidity, mortality and outcome after SLT for LAM in a lung transplant center in Japan.MethodsWe reviewed the records of 29 patients who underwent SLT for LAM in our hospital between March, 2000 and November, 2017. The data collected included the pre-transplant demographics of recipients, surgical characteristics, complications, morbidity, mortality and survival after SLT for LAM.ResultsThe most common complication after SLT for LAM was contralateral pneumothorax (n = 7; 24.1%). Six of these recipients were treated successfully with chest-tube placement and none required surgery for the pneumothorax. The second-most common complication was chylous pleural effusion (n = 6; 20.7%) and these recipients were all successfully treated by pleurodesis. The 5-year survival rate after SLT for LAM was 79.5%.ConclusionLAM-related complications after SLT for this disease can be managed. SLT is a treatment option and may improve access to lung transplantation for patients with end-stage LAM.
