BACKGROUND： Liver resection is currently the most efficient curative approach for a wide variety of liver tumors. The application of modern techniques and new surgical devices has improved operative outcomes. Radiofrequency ablation is used more often for liver parenchymal transection. This study aimed to assess the efficacy and safety of radiofrequency ablation-assisted liver ***： A retrospective study of 145 consecutive patients who underwent radiofrequency ablation-assisted liver resection was performed. Intraoperative blood loss, need for transfusion or intraoperative Pringle maneuver, the duration of liver parenchymal transection, perioperative complications, and postoperative morbidity and mortality were all ***： Fifty minor and ninety-five major liver resections were performed. The mean intraoperative blood loss was 251 m L, with a transfusion rate of 11.7%. The Pringle maneuver was necessary in 12 patients（8.3%）. The mean duration for parenchymal transection was 51.75 minutes. There were 47 patients（32.4%） with postoperative complications. There is no mortality within 30 days after surgery. CONCLUSIONS： Radiofrequency ablation-assisted liver resection permits both major and minor liver resections with minimal blood loss and without occlusion of hepatic inflow. Furthermore it decreases the need for blood transfusion and reduces morbidity and mortality.

Associations among benign prostate hypertrophy, atypical adenomatous hyperplasia and latent carcinoma of the prostate

Aim： To investigate the frequency of atypical adenomatous hyperplasia （AAH） and its associations with benign prostate hypertrophy （BPH） and latent histological carcinoma of the prostate （LPC） in autopsy material. Methods： Two hundred and twelve prostate specimens obtained from autopsy material were subjected to whole mount analysis in an attempt to investigate the associations among BPH, AAH and LPC. Results： Most histological carcinomas and AAH lesions were found in enlarged prostates with intense hypertrophy. No statistically significant relation was found between BPH and the main characteristics of LPC, such as tumor volume, histological differentiation and biological behavior. Our data regarding multi-focal tumors showed a tendency for multi-focal carcinomas to develop in larger prostates, and a tendency of AAH lesions to develop in larger prostates. No statistically significant relation was found between AAH and LPC. Conclusion： There seems not any causative aetiopathogenetical or topographical relation between AAH lesions and prostate adenocarcinoma. AAH lesion seems to be a well-defined mimicker of prostatic adenocarcinoma, and the reported association of AAH with prostatic carcinoma could probably be an epiphenomenon.
