From July, 2015 to December, 2022, 127 patients who underwent resection of three or more adjacent liver segments (major hepatectomy) were retrospectively reviewed. Aortic...
The spleen has been reported to inhibit liver regeneration following hepatectomy; however, the underlying mechanisms remain poorly understood. In particular, its role in future liver remnant (FLR) regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) warrants investigation. To evaluate the relationship between splenic volume...
Carpal Tunnel Syndrome (CTS) is a painful orthopedic hand condition caused by compression of the median nerve at the wrist. Diagnosis is typically clinical, relying on patient’s symptoms and physical examination findings, but confirmation often requires electrodiagnostic studies. Previous research on CTS has explored the relationship between median nerve compression severity and...
Frailty is a heightened vulnerability to stress due to decreased physical and mental abilities. Preoperative frailty has been associated with poorer outcomes. However, frailty is not static, and those patients who eventually die appear to become more frail. Our hypothesis is in-patient, postoperative changes in frailty after major operations predicts the trajectory to...
Following liver resection (LR), recurrence is critical to the prognosis of hepatocellular carcinoma (HCC). A higher level of alpha-fetoprotein (AFP) is typically associated with poor prognosis and recurrence concerns. Specifically, we attempted to determine whether high AFP (> 1,000ng/ml) and other potentially relevant factors affect survivals of patients with BCLC stage 0 HCC...
