Trends in morbidity and mortality of hepatic resection for malignancy. A matched comparative analysis.

Objective: The authors define more clearly the trends in morbidity and mortality after hepatic resection for malignant disease in matched patient groups during two discrete time periods.

Summary Background Data: Recent reports have shown improvement in operative morbidity and mortality associated with hepatic resection; however, results often included resections for benign disease and trauma. Furthermore, specific factors contributing to the improvement in operative risks between the last two decades have not been defined.

Perioperative blood transfusion and determinants of survival after liver resection for metastatic colorectal carcinoma.

The authors reviewed their institutional experience with liver resection for metastatic colorectal carcinoma to (1) determine whether perioperative blood transfusion affects survival; (2) identify prognostic determinants; and (3) estimate the patient requirement for a prospective randomized trial designed to demonstrate efficacy of liver resection. Two hundred eighty consecutive patients treated by potentially curative liver resection between 1960 and 1987 were included. Data were obtained for all but 10 patients for at least 5 years after operation or through 1990.

Intrahepatic cholangiocarcinoma: clinical aspects, pathology and treatment.

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary tumor of the liver. To further define its clinicopathology and surgical management, we reviewed our experience. Clinical presentations of 32 patients with ICC was similar to that with hepatocellular carcinoma.

Controlled expansion of peripheral nerves: comparison of nerve grafting and nerve expansion/repair for canine sciatic nerve defects.

The inherent disadvantages of nerve grafting have made it necessary to find alternative techniques for treating segmental nerve loss. This study compares the techniques of nerve grafting and nerve expansion/repair for the management of nerve injuries with segmental nerve loss in an animal model. Bilateral segmental sciatic nerve defects were created in eight dogs.
