BACKGROUND: We investigated the advantages of intraoperative transesophageal echocardiography (TEE) during inferior vena caval tumor thrombectomy in renal cell carcinoma (RCC). METHODS: Five patients with RCC that extended into the inferior vena cava (IVC) underwent radical nephrectomy. To remove the tumor thrombus in the IVC, an inflated Fogarty balloon catheter was used to pull the thrombus below the level of the hepatic veins with real-time TEE monitoring. RESULTS: In all cases, TEE monitoring during surgery provided an accurate and excellent view of the IVC thrombus. TEE was particularly helpful for the thrombectomy to minimize hepatic mobilization by using occlusion balloon catheter in two patients whose thrombus extended to the intrahepatic IVC. CONCLUSIONS: Intraoperative real-time TEE monitoring is a safe, minimally invasive technique that can provide accurate information regarding the presence and extent of IVC involvement, guidance for placement of a vena caval clamp, confirmation of complete removal of the IVC thrombus and intervention using catheters to assist in thrombectomy.

[Pain control with epidural anesthesia for uterine artery embolization].

BACKGROUND: To reduce the severity of post procedure pain associated with uterine artery embolization (UAE) for leiomyomata, we used continuous infusion of low concentration ropivacaine through an epidural catheter. METHODS: Thirteen patients for UAE were evaluated. In a patient without indication for epidural anesthesia, the pain was controlled with intermittent morphine infusion. Other patients had post procedure pain managed with 10 ml bolus of 1% lidocaine and continuous infusion of 0.2% ropivacaine at 5 ml x hr-1 for 16 hours. RESULTS: The patient complained of severe pain just after UAE and required epidural lidocaine. Then, we started to infuse lidocaine or ropivacaine just before starting UAE. Among these cases, 9 patients required extra pain control using NSAIDs as a rescue. Only three patients required no medication except epidural analgesia. CONCLUSIONS: Continuous infusion of 0.2% ropivacaine at a rate of 5 ml x hr-1 is not enough for pain management after UAE.

Relationship between hepatocellular carcinoma and impaired glucose tolerance among Japanese.

BACKGROUND/AIMS: Both the incidence of diabetes mellitus (DM) and mortality from Hepatocellular carcinoma (HCC) are increasing in Japan. As the association of overall cancer and HCC with impaired glucose tolerance (IGT) has been studied rarely in the world including Japan, this study assessed their associations using cohort data of Hokkaido, Japan. METHODOLOGY: After getting ethical consent, this study included 908 men and 1,081 women aged 30-77 years during 1977-78 and collected detailed information using the baseline survey. The subjects were followed until 2002 and deaths were recorded using ICD-9. Classifying them into three groups of diabetes status namely DM, IGT, and normal, the relative risk (RR) of mortality was estimated by diabetes status using multivariate Cox model. RESULTS: This study revealed no association between overall cancer and diabetes status. However, the RR of mortality from HCC was about 11 times (HR= 10.8, 95%CI: 1.3-92.5) higher in IGT compared with normal group. DM group also showed higher risk of mortality than normal group. CONCLUSIONS: HCC mortality was significantly high among IGT group. However, as the results of the study were based on small data, further studies with large cohort are needed to address the association of IGT with overall cancer and HCC mortality in Japan.
