BACKGROUND: To investigate the effects of acute kidney injury (AKI) after liver resection on the long-term outcome, including mortality and renal dysfunction after hospital discharge. METHODS: We conducted a historical cohort study of patients who underwent liver resection for hepatocellular carcinoma with sevoflurane anesthesia between January 2004 and October 2011, survived the hospital stay, and were followed for at least 3 years or died within 3 years after hospital discharge. AKI was diagnosed based on the Acute Kidney Injury Network classification within 72 hours postoperatively. In addition to the data obtained during hospitalization, serum creatinine concentration data were collected and the glomerular filtration rate (GFR) was estimated after hospital discharge. RESULTS: AKI patients (63%, P = 0.002) were more likely to reach the threshold of an estimated GFR (eGFR) of 45 ml/min/1.73 m² within 3 years than non-AKI patients (31%) although there was no significant difference in mortality (33% vs. 29%). Cox proportional hazard regression analysis showed that postoperative AKI was significantly associated with the composite outcome of mortality or an eGFR of 45 ml/min/1.73 m² (95% CI of hazard ratio, 1.05–2.96, P = 0.033), but not with mortality (P = 0.699), the composite outcome of mortality or an eGFR of 60 ml/min/1.73 m² (P =0.347). CONCLUSIONS: After liver resection, AKI patients may be at higher risk of mortality or moderate renal dysfunction within 3 years. These findings suggest that even after discharge from the hospital, patients who suffered AKI after liver resection may need to be followed-up regarding renal function in the long term.

During the coronavirus pandemic, we focused on Hypothesis-Driven Physical Examination (HDPE), which is performed while considering physical examination and differential diagnosis as issues that can be learned without directly having contact with patients. We created HDPE scenarios with students who elected general medicine in Clinical Clerkship 2, and we implemented HDPE using that scenario on the last day of the clerkship. The scenario was created online and HDPE was conducted face-to-face. Students could learn correct medical examination techniques and manners through mutual learning. In addition, they could acquire communication and lifelong learning abilities through cooperative learning. We were able to enhance the learning effect through mutual learning that works on the students’ own intrinsic motivation in terms of both creating scenarios for the framework of cognitive apprenticeship and implementing HDPE.
