In addition, to evaluate learning curve of LA, the patients were divided into two groups according to time interval: the first period was 2006 to 2011, and the second period 2012-2017.Main outcome measures: To evaluate the risk of learning curve and tumour sizeResults: There was no statistical difference between the two groups for per-operative and postoperative complications according to tumour size <5 or >= 5 cm, and there was statistical difference between the two groups for operation time, length of hospital stay; but no statistical difference for postoperative complications according to time interval.Conclusion: LA in large adrenal masses (5 cm or larger) is not associated with longer operative time, increased blood loss and longer hospital stay, without affecting perioperative morbidity, Hence, the size of an adrenal mass should not be the only factor in determining whether LA or not. Besides, learning curve may affect outcomes of LA.eninfo:eu-repo/semantics/closedAccessPosterior retroperitoneoscopic adrenalectomyAdrenocortical carcinomaTumorsCmAdrenalAdrenalectomyLaparoscopyLearning curveOncologyScience & technologyLife sciences & biomedicineMedicine, general & internalGeneral & internal medicineArticle001087350700002463468544
