    Abstract Kawakami and colleagues report a case of duodenoscope insertion difficulty through the pyloric ring due to perigastric adhesions which was successfully overcome using an overtube. The overtube can be attached to both standard and therapeutic duodenoscopes, allowing successful biliary or pancreatic intervention in patients in whom duodenoscopic insertion is challenging.

    Abstract Comprehensive genomic profiling based on next-generation sequencing has recently been used to provide precision medicine for various advanced cancers. Endoscopic ultrasound (EUS)-guided fine-needle aspiration (EUS-FNA) and EUS-guided fine-needle biopsy (EUS-FNB) play essential roles in the diagnosis of abdominal masses, mainly pancreatic cancers. In recent years, CGP analysis using EUS-FNA/FNB specimens for hepatobiliary-pancreatic cancers has increased; however, the success rate of CGP analysis is not clinically satisfactory, and many issues need to be resolved to improve the success rate of CGP analysis. In this article, we review the transition from EUS-FNA to FNB, compare each test, and discuss the current status and issues in genomic analysis of hepatobiliary-pancreatic cancers using EUS-FNA/FNB specimens.

    Abstract Introduction: The global incidence of cardiovascular disease (CVD) is high, and the medical costs associated with its management have been increasing. Cost-utility analyses (CUAs) are essential for understanding the value of healthcare interventions and for decision-making. A majority of the CUAs for CVD are model based and have cited health utilities from previously published data; standard health utilities for the CUAs of CVD have not been established yet. Thus, we aim to identify the standard utilities according to the patients' condition and disease severity in patients with major CVDs.
    Methods and analysis: We will search Medline and Evidence-Based Medicine Reviews for trial-based CUA studies that have reported on quality-adjusted life-years using original health utilities for patients with three major forms of CVD (coronary artery disease, heart failure and atrial fibrillation). Papers on trial-based CUAs will be included, while those on model-based CUAs will be excluded. No restrictions will be made in terms of intervention type. The main outcome comprises the health utilities calculated on a scale of 0-1 (irrespective of the measurement methods) at baseline and after treatment. Two independent investigators will screen the eligibility of articles; they will extract data, including health utilities, from the eligible articles for further analysis. The quality of the included studies will be assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. We will describe the means and SDs of the health utilities from all the included studies. The mean utility weights for individual studies will be combined through meta-analyses using a random-effects model to obtain the representative health utility value for each disease. Subgroup analyses will be conducted according to the severity and duration of each disease.
    Ethics and dissemination: Ethical approval is not required. The review will be submitted to an appropriate peer-reviewed journal.

    Abstract Nowadays, the novel molecular targeting chemotherapy provides possibility of safe hepatectomy for progressive hepatocellular carcinoma (HCC). Further, combination of the conventional transarterial chemoembolization (TACE) may add an effect of tumor shrink. We present a successful radical hepatectomy for a large HCC located in segment 1 accompanied with the preoperative Lenvatinib (LEN)-TACE sequential treatment. We present a woman patient without any complaints who had a 7 cm-in-size of solitary HCC compressing vena cava and right portal pedicle. To achieve radical hepatectomy by tumor shrinking, LEN-TACE for 2 months. After confirming downsizing or devascularization of the HCC, we scheduled radical posterior sectionectomy combined with caudate lobectomy according to tumor location and expected future remnant liver volume from three-dimensional computed tomography simulation before surgery. Under the thoraco-abdominal incision laparotomy, we safely achieved scheduled radical hepatectomy without any vascular injuries. The postoperative course was uneventful and no tumor recurrence were observed for 1 year. Histological findings showed the Japan TNM stage III HCC with 70% necrosis. The multi-modal strategy of LEN-TACE followed by radical hepatectomy by confirming downsizing or devascularization in tumor is supposed to be useful and would be a preoperative chemotherapy option, and promising for curative treatment in HCC patients with progressive or large HCC, which may lead to safety by prevention surrounding major vascular injury.

    Abstract Hepatitis C virus (HCV) reactivation has been reported to be caused due to several anticancer drugs and immunosuppressive agents; however, HCV reactivation after steroid monotherapy has rarely been reported. Here, we report the case of a 65-year-old Japanese man with HCV infection who developed HCV reactivation after the administration of prednisolone (PSL) for 6 days for sudden deafness. In the patient history, the positivity for anti-HCV antibody was observed, but serum level of HCV RNA was not measured. Two months after PSL administration, the patient experienced an alanine aminotransferase (ALT) flare and the serum level of HCV RNA was observed to be 6.2 log IU/mL; then, the patient was admitted to our hospital for hepatitis treatment. Based on the clinical course and laboratory findings, the patient was diagnosed with HCV reactivation. Although the ALT levels decreased spontaneously during follow-up, they did not drop to normal range; subsequently, sofosbuvir and ledipasvir treatments were started. A sustained virological response 24 weeks after the end of treatment was achieved. This case study suggests that HCV reactivation with hepatitis flare can occur even after a steroid monotherapy, and doctors should pay attention to HCV reactivation when administering PSL for patients with HCV infection.

    Abstract Highlight Kawakami and UMIDAS Inc. developed a novel biliary drainage system consisting of a 7- or 8.5-Fr inside biliary stent, a 4-Fr nasobiliary drainage catheter and a 7.5-Fr pushing catheter. It is the least invasive approach available for the management of acute cholangitis and biliary drainage in patients with benign and malignant perihilar biliary obstruction.
