    Notes: Abstract: The extent of cancerous invasion of the inferior vena cava (IVC) determined from resected liver cancer was examined pathologically. Ten patients presenting with liver cancer (metastatic liver cancer, five patients; hepatocellular carcinoma, three; and cholangiocellular carcinoma, two) were diagnosed with positive IVC invasion using preoperative imaging techniques of extracorporeal ultrasonography, computed tomography, magnetic resonance imaging, and vena cavography. The diagnostic criterion for positive IVC invasion by preoperative imaging was longitudinal IVC compression measuring over 50 mm, or transverse IVC compression extending to more than half the circumference of the IVC, or the presence of lesions protruding into the IVC lumen, or the presence of developed collateral veins. All patients underwent combined resection of the IVC. However, pathology results revealed that four of the ten patients had no cancerous invasion of the IVC, and that the extent of invasion along both the longitudinal and transverse axes of the IVC was much smaller than the compression shown by imaging results. We believe that detailed preoperative assessment, using a more precise imaging technique, as well as further intraoperative examination, is required to predict the full pathological extent of cancerous invasion of the IVC.

    Notes: Abstract We describe herein the case of a 21-year-old woman in whom Castleman disease of the pararenal retroperitoneum was successfully resected. The patient was referred to our hospital from another hospital for investigation of a retroperitoneal mass in the right middle abdomen. Ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large retroperitoneal mass with heterogeneous imaging characteristics. An aortogram showed arterial feeding to this mass from a few lumbar arteries. Although a definitive preoperative diagnosis could not be made, surgical excision was performed and histopathological examination confirmed a diagnosis of the hyaline type of Castleman disease. The patient had an uneventful postoperative course and was discharged 14 days after her operation. She now leads an active social life without any signs of sequelae or recurrence 14 months later. To the best of our knowledge, only 2% (6/315) of all reported cases of Castleman disease have been located in the pararenal and retroperitoneal area.

    Notes: Abstract: Hepatoduodenal ligamentectomy (ligamentectomy) is the ultimate surgery for biliary tract carcinoma involving perioperative difficulties such as total hepatic ischemia during revascularization of the hepatic artery and the portal vein, patency of the reconstructed hepatic artery, and high incidence of related operative mortality. In the present study, modified ligamentectomies with extended right hepatic lobectomy, including resection of the caudate lobe, were performed on three patients with advanced biliary tract carcinoma in whom the left hepatic artery had been replaced and the original artery was preserved. In all patients, postoperative courses were uneventful: success of the resection was confirmed by histological examination. This procedure enabled en bloc resection of hepatoduodenal ligament with positive cancer invasion to take place. It was carried out safely without concern for the difficulties described above. In our view, ligamentectomy should be performed in all such cases.
