Ida M, et al. - Via this retrospective review of 208 patients (≥age 20) who underwent pancreaticoduodenectomy or distal pancreatectomy, researchers assessed the factors related to post-operative complications, focusing on pre-operative hematologic markers such as the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and prognostic nutritional index. The outcomes of interest were reoperation and unplanned intensive care unit admission prior to the first discharge (primary outcome) as well as length of hospital stay (secondary outcome). Findings revealed a significant association of neutrophil-to-lymphocyte ratio and blood loss volume with post-operative complications, resulting in prolonged hospitalization.
