Lobar size reduction in lung transplantation: A propensity score study

Abstract

Objective: For small-sized recipients of lung transplantation, the time span for organ reception from standard donors is generally longer than for normal-sized patients. Despite its underuse, lobar reduction may be a concrete option for these patients. This study aims to assess early and long-term outcomes associated with lobar reduction in lung transplantation. Methods: A retrospective study was performed on 608 consecutive lung transplantations at 2 centers between January 2005 and August 2019 (559 standard lung transplantations [standard transplantation] and 49 with lobar reduction [lung transplantation group]). A propensity-score weighting approach was used to account for potential confounding related to patients' nonrandom allocation to the 2 intervention groups. The effects of the intervention on postoperative outcomes were assessed with a weighted regression approach. Results: The propensity score was estimated on 571 patients (522 in standard transplantation group and 49 in lung transplantation group). In terms of early outcomes, the lung transplantation group showed a higher percentage of severe primary graft dysfunction at 0 hours and reported longer intensive care unit stay than the standard transplantation group. No other differences in terms of morbidity, mortality, mechanical ventilation time, hospital stay, and anastomotic complications were observed. Although the lung transplantation group showed worse long-term pulmonary function, the 2 populations had comparable survival outcomes. Conclusions: The use of lobar reduction showed early and long-term results comparable to those after standard lung transplantation. Although a higher rate of early severe primary graft dysfunction and slightly reduced respiratory function were detected in the lobar group, these did not affect patients' morbidity and survival.
