Calculate mortality risk that accounts for both severity and recovery of postoperative kidney dysfunction using the pattern of longitudinal change in creatinine. ⋯ We demonstrate the nonlinear relationship between both severity and recovery of renal dysfunction and 90-day mortality after major surgery. We have developed an easily applicable computer algorithm that calculates this complex relationship.

To identify factors predicting the development of high-risk lesions in the remnant pancreas after surgery for intraductal papillary mucinous neoplasm (IPMN). ⋯ Patients undergoing partial pancreatectomy for IPMN are at high risk of developing lesions requiring surgery in the remnant pancreas, and close, long-term surveillance should be considered in these patients.

To determine optimal settings for airway pressure (AWP), pneumoperitoneum pressure (PPP), and central venous pressure (CVP) in pure laparoscopic hepatectomy. ⋯ By increasing pneumoperitoneum pressure, bleeding from the hepatic vein cannot be controlled under high airway pressure, but can be controlled under low airway pressure. However, under low airway pressure, the risk of pulmonary gas embolism increases when PPP is higher than CVP. We consider that reducing AWP is also effective for controlling bleeding from the hepatic vein and safer than increasing pneumoperitoneum pressure.
