Effects of the Preoperative Use and Dosage of Steroids on Postoperative Complications of Gastric Cancer Surgery.

To investigate the effects of preoperative steroid administration, including dosage, on complications after gastrectomy for gastric cancer. We reviewed patients who underwent gastrectomy for gastric and esophagogastric junctional adenocarcinoma between 2013 and 2019 at the Department of Gastrointestinal Surgery, The University of Tokyo. Among the total 764 patients eligible for inclusion in the study, 17 were on steroid medication preoperatively (SD group) and 747 were not (ND group). The hemoglobin, serum albumin levels, and respiratory functions were significantly lower in the SD group than in the ND group. The incidence of postoperative complications classified as Clavien–Dindo (C–D) ≥ 2 was significantly greater in the SD group than in the ND group (64.7
