An ICGK-F of 0.05 is a useful cut-off value for predicting mortality and morbidity. With careful perioperative patient management in an experienced institution, this cut-off value can be lowered further.

Optimizing these factors, where possible, before PVE or PH, is essential to maximize hypertrophy of the liver. A fuller understanding of hepatic physiology and pathophysiology following PVE or PH may lead to greater functional capacity of the remaining liver and extend the indications for hepatectomy in patients who require large liver volume resection.

Obturator hernia is relatively rare and occurs mostly in elderly, thin, multiparous women. Recent reports have highlighted the importance of pelvic computed tomography (CT) for the preoperative diagnosis. Thirty-six patients with an obturator hernia operated in our hospital were divided retrospectively into two groups (group A: 18 operations from 1973 to 1986, before we used CT; group B: 18 CT cases from 1987 to 1995). Preoperative diagnoses, operative procedures, and postoperative course were r

ICGK-F is useful in predicting the PHLF and mortality in patients undergoing major hepatectomy with extrahepatic bile duct resection. This criterion may be useful for highly invasive hepatectomy, such as that with extrahepatic bile duct resection.

Although the mechanisms of cirrhosis-induced portal hypertension have been studied extensively, the role of thromboxane A(2) (TXA(2)) in the development of portal hypertension has never been explicitly explored. In the present study, we sought to determine the role of TXA(2) in bile duct ligation (BDL)-induced portal hypertension in Sprague-Dawley rats. After 1 wk of BDL or sham operation, the liver was isolated and perfused with Krebs-Henseleit bicarbonate buffer at a constant flow rate. After
