Background: s/Aims: Patients with hepatocellular carcinoma (HCC) and histologically confirmed F4 cirrhosis often have limited hepatic reserve, making major hepatectomy difficult. Although laparoscopic liver resection is increasingly performed, its perioperative safety in this setting remains unclear. This study compared laparoscopic and open partial hepatectomy in these patients using propensity score matching (PSM). Methods: Among 298 patients who underwent hepatectomy for HCC between 2006 and 2023, 112 with histologically confirmed F4 cirrhosis who underwent partial hepatectomy were included (laparoscopic, n = 60; open, n = 52). PSM was performed using previous liver resection, difficulty score, tumor size, tumor number, and platelet count, yielding 32 matched pairs. Outcomes included operative time, blood loss, transfusion requirements, complications, hospital stay, posthepatectomy liver failure (PHLF), R0 resection rate, and 30-day mortality. Results: After matching, intraoperative blood loss was significantly lower in the laparoscopic group than in the open group (50 mL vs. 295 mL, p < 0.001). Operative time, transfusion rate, complication rate, R0 resection rate, and 30-day mortality were comparable between groups. Hospital stay was significantly shorter in the laparoscopic group (13 vs. 22 days, p < 0.001). Grade A PHLF occurred in one patient in the open group, with no significant between-group difference. Conclusions In patients with HCC and histologically confirmed F4 cirrhosis, laparoscopic partial hepatectomy was associated with less blood loss and shorter hospital stay than open surgery, without increasing perioperative morbidity. It may be a safe option in carefully selected patients undergoing limited liver resection.

Purpose：We investigated the factors associated with medical device-related pressure ulcer (MDRPU) due to lower extremity orthosis in patients undergoing convalescent rehabilitation for stroke.Methods：This retrospective study included patients with stroke who wore ankle foot orthosis in the convalescent rehabilitation ward. We measured the following items at admission：Brunnstrom recovery stage, presence of sensory disturbance, exhibition of unilateral spatial neglect, functional independence measures at admission and discharge, and presence of MDRPU. In the statistical analysis, logistic regression analysis was performed to identify the significant factors associated with MDRPU.Results：Ninety-five participants were enrolled in this study (mean age：54.9 ± 11.6 years, Male：78.9%). In logistic regression analysis, Age (odds ratio＝1.05, 95% confidence interval＝1.01-1.10, p＜0.05) and the presence of sensory disturbance (odds ratio＝5.17, 95% confidence interval＝1.39-19.28, p＜0.05) at admission was extracted as the cause of MDRPU.Conclusion：Sensory disturbance at admission is associated with MDRPU in patients undergoing convalescent rehabilitation for stroke who wear ankle foot orthosis.
