The treatment of patients with diabetes mellitus (DM) is enormously expensive in developed countries because of its high prevalence and complications. DM patients often experience microvascular and macrovascular complications that affect their postoperative course, and are at significantly higher risk of postoperative infection and postoperative cardiovascular morbidity and mortality. In addition, few studies have evaluated inpatient care resource use in DM patients who have undergone gastrectomy for gastric cancer. The purpose of this study was to quantify differences in inpatient care resource use and postoperative complications among insulin-using diabetes mellitus patients (IDM), non-insulin-using diabetes mellitus patients (NIDM), and patients without diabetes mellitus (NDM) who had undergone partial gastrectomy for gastric cancer. We analyzed data from 1,805 patients who had undergone partial gastrectomy for gastric cancer. The numbers of patients in the IDM, NIDM, and NDM groups were 82 (4.5%), 61 (3.4%), and 1,662 (92.1%), respectively. The IDM group had a significantly longer length of stay, higher total charge, and higher risk of postoperative complications than the NDM group. However, the NIDM group did not have increased inpatient care resource use or a higher incidence of postoperative complications compared with the NDM group. Healthcare providers should consider the differences in healthcare resource use and postoperative complications between IDM and NIDM patients.
