Backgraund/Aim/Method: Hepatocellular carcinoma (HCC) is a serious life-threatening disease. When HCC is advanced, moderate to severe pain is frequently found due to bone metastasis, requiring the administration of opioids. However, HCC develops in cirrhotic liver in most cases those are decreased in drug metabolism. Careful monitoring is therefore required when opioids are administered to patients with cirrhosis or HCC because guidelines about the administration of opioids are not established in Japan. In this report, we retrospectively analyzed cases treated by opioids and discussed about problems in current opioid treatment for advanced HCC cases. Results: The median duration of opioid treatment is about two months, and seems to be prolonged in cases with treatment of HCC. Prophylaxes for hepatic encephalopathy were done in about 10% of cases, and hepatic encephalopathy was developed in about 40% of cases after opioid treatment. Conclusion: In administration of opioids for advanced HCC, we should consider the onset of hepatic encephalopathy and make an effort to prevent it.

Endoscopic papillectomy (EP) for ampullary adenomas achieves cure rates ranging from 76% to 90%, and recurrence rates are as high as 33%. If remnant or recurrent lesions after prior EP are endoscopically visible and are not suspected of intraductal extension into the biliary or pancreatic duct, repeated snaring and cutting can be performed until all visible lesions are completely resected. However, endoscopic ablative therapies, particularly argon plasma coagulation, can be attempted for tiny or uncertain remnant and recurrent lesions. In addition, intraductal radiofrequency ablation has recently been attempted for residual intraductal lesions after EP at several institutions. Although still under investigation, it has shown some promise. It might be offered as an alternative to surgery, particularly in patients who are unfit for surgery or those who refuse to undergo surgery.
