Efficacy and Validity of Percutaneous Transhepatic Gallbladder Drainage as a Bridge to Surgery for Octogenarian and Older Patients With Acute Cholecystitis: A Single-Center Retrospective Observational Study in Japan.

Background: Japan currently has a super-aged society, with a rapid increase in elderly patients in need of medical care. Determining treatment strategies for acute cholecystitis (AC) in very elderly patients with various comorbidities is often difficult. Although percutaneous cholecystostomy (PC) is a less-invasive treatment option, its impact on subsequent surgery remains debatable.

Accidental duodenal foreign body of toothbrush removed laparoscopically: a case report.

Background: Foreign body ingestion is a common case in daily medical care, and it usually passes through the entire gastrointestinal tract naturally and is excreted in the feces. However, long and sharp foreign bodies may be difficult to pass naturally due to their shape. Here, we present a rare case of a duodenal foreign body, a toothbrush, that required laparoscopic surgical removal after a failed endoscopic attempt.

Effect of combined farnesoid X receptor agonist and angiotensin II type 1 receptor blocker on ongoing hepatic fibrosis.

Objective: Nonalcoholic steatohepatitis (NASH) is difficult to diagnose in patients with no symptoms. We aimed to investigate the combined effect of farnesoid X receptor (FXR) agonist, obeticholic acid (OCA), and angiotensin II type 1 receptor blocker (ARB: losartan) on an ongoing hepatic fibrosis in a NASH rat model.

Methods: Fischer 344 rats were fed with choline-deficient L-amino-acid-defined (CDAA) diet for 16 weeks.

[An autopsy case of hepatic angiosarcoma diagnosed with ultrasonography-guided percutaneous needle biopsy of the liver].

Contrast medium-enhanced computed tomography revealed a mass in the liver of a 65-year-old man. The edge but not the center of the mass was enhanced. Ultrasonography-guided percutaneous needle biopsy revealed the diagnosis of angiosarcoma of the liver, and it was treated with chemotherapy.

Comparison of 22G standard and Franseen needles in endoscopic ultrasound-guided fine-needle aspiration for diagnosing pancreatic mass lesions: Study protocol for a controlled trial.

Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was developed with the aim of further improving the diagnostic performance of endoscopic ultrasound. Although novel puncture needles have been specifically designed for collecting sufficient tissue specimens, clinical studies have indicated no clear difference in diagnostic performance between these novel needles and conventional puncture needles. Recently, a needle with Franseen geometry was developed specifically for EUS-FNA biopsy.

Combined effect of a farnesoid X receptor agonist and dipeptidyl peptidase-4 inhibitor on hepatic fibrosis.

Aim: Non-alcoholic steatohepatitis (NASH) has a broad clinicopathological spectrum (inflammation to severe fibrosis). The farnesoid X receptor agonist obeticholic acid (OCA) ameliorates the histological features of NASH; satisfactory antifibrotic effects have not yet been reported. Here, we investigated the combined effects of OCA + a dipeptidyl peptidase-4 inhibitor (sitagliptin) on hepatic fibrogenesis in a rat model of NASH.

Diagnostic Efficacy of Liquid-Based Cytology in Endoscopic Ultrasound-Guided Fine Needle Aspiration for Pancreatic Mass Lesions During the Learning Curve: A Retrospective Study.

Objectives: The diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology widely varies depending on the treatment method used. Liquid-based cytology (LBC) has gained popularity in the gynecological field because of its efficacy in collection of target cells and simplicity in the manipulation of specimens. Since the introduction of EUS-FNA at our institution, we have used LBC for the diagnosis of pancreatic mass lesions.

Identification of clinical risk factors for histological progression of primary biliary cholangitis.

Aim: To identify laboratory predictors of histological progression (HP) of primary biliary cholangitis (PBC).

Methods: Sequential biopsies were carried out on 35 (11.4%) of 308 patients with PBC treated with ursodeoxycholic acid (UDCA).

Calcified mucinous adenocarcinoma of the stomach metastatic to the iris: a case report.

Background: Gastric cancer has a wide spectrum of clinical features, imaging manifestations, and pathology. Punctate calcifications in gastric cancer are infrequent but are usually found in mucinous adenocarcinoma. However, there have only been a few autopsy case reports describing the correlation between the radiology and pathology findings of calcified mucinous adenocarcinoma of the stomach.

Efficacy of L-carnitine on ribavirin-induced hemolytic anemia in patients with hepatitis C virus infection.

Background/aims: L-carnitine not only alleviates hyperammonemia and reduces muscle cramps in patients with liver cirrhosis, but also improves anemia in patients with chronic hepatitis and renal dysfunction. This study prospectively evaluated the preventative efficacy of L-carnitine supplementation against hemolytic anemia during antiviral treatment using ribavirin in patients with hepatitis C virus (HCV)-related chronic liver disease.

Methods: A total of 41 patients with chronic hepatitis were consecutively enrolled in this study.

[Ruptured ascending colonic varices in a patient with alcoholic liver cirrhosis treated using topical skin adhesive:a case study].

A 59-year-old man had been admitted to our hospital because of general malaise and abdominal fullness caused by massive ascites. He was diagnosed with alcoholic liver cirrhosis. Following the removal of ascites, he was referred to our department because of hematochezia.

Acyclic retinoid and angiotensin-II receptor blocker exert a combined protective effect against diethylnitrosamine-induced hepatocarcinogenesis in diabetic OLETF rats.

Background: Insulin resistance (IR) is closely associated with the progression of hepatocellular carcinoma (HCC). Acyclic retinoid (ACR) targets retinoid X receptor α and reportedly prevents HCC recurrence in clinical practice. Angiotensin-II receptor blocker (ARB) can also inhibit experimental hepatocarcinogenesis and HCC development.

von Willebrand factor is a useful biomarker for liver fibrosis and prediction of hepatocellular carcinoma development in patients with hepatitis B and C.

Background: Several noninvasive biomarkers are available for diagnosing liver fibrosis stage and predicting hepatocellular carcinoma (HCC) development in patients with chronic hepatitis and liver cirrhosis. However, these biomarkers are not sufficiently accurate. Recently, von Willebrand factor (VWF) has been related to angiogenesis and apoptosis.

Combining probiotics and an angiotensin-II type 1 receptor blocker has beneficial effects on hepatic fibrogenesis in a rat model of non-alcoholic steatohepatitis.

Aim: Intestinal endotoxin is important for the progression of non-alcoholic steatohepatitis (NASH). Circulating endotoxin levels are elevated in most animal models of diet-induced non-alcoholic fatty liver disease (NAFLD) and NASH. Furthermore, plasma endotoxin levels are significantly higher in NAFLD patients, which is associated with small intestinal bacterial overgrowth and increased intestinal permeability.

Efficacy and tolerability of interferon-free regimen for patients with genotype-1 HCV infection.

Depression is a major reason for interferon (IFN) therapy cessation. IFN-free direct-acting antiviral (DAA) therapy for depression is not well-documented. Thus, four different IFN-free regimens were assessed in genotype-1 hepatitis C virus (HCV) patients with depression.

Proton pump inhibitor therapy does not increase serum endotoxin activity in patients with cirrhosis.

Aim: Proton pump inhibitors (PPIs) are frequently prescribed in patients with cirrhosis, but this therapy entails potential complications. We aimed to investigate the influence of PPI use on intestinal permeability in patients with cirrhosis.

Methods: We recruited 228 patients with cirrhosis and divided them into four groups.

Efficacy of bi-monthly hepatic arterial infusion chemotherapy for advanced hepatocellular carcinoma.

Background: Even though the Barcelona Clinic Liver Cancer (BCLC) staging system is widely accepted, controversies on the management of hepatocellular carcinoma (HCC) still exist. We evaluated the efficacy of an approach with repeated hepatic arterial infusion chemotherapy (HAIC) given at eight-week intervals for the treatment of advanced HCC.

Methods: Of the 66 compensated cirrhotic patients with advanced HCC refractory to transcatheter arterial chemo-embolization (TACE) enrolled in our study, 21 were treated by bi-monthly hepatic arterial infusion chemotherapy (B-HAIC) and the rest by sorafenib.

Oral administration of fructose exacerbates liver fibrosis and hepatocarcinogenesis via increased intestinal permeability in a rat steatohepatitis model.

Recent reports have revealed the impact of a western diet containing large amounts of fructose on the pathogenesis of non-alcoholic steatohepatitis (NASH). Fructose exacerbates hepatic inflammation in NASH by inducing increasing intestinal permeability. However, it is not clear whether fructose contributes to the progression of liver fibrosis and hepatocarcinogenesis in NASH.

[Short-term sustained virological response in a patient with liver cirrhosis, hepatitis C, and declining hepatic spare ability during treatment with direct-acting antivirals].

A 75-year-old female patient with liver cirrhosis and hepatitis C was treated with direct-acting antivirals (DAA) (Sofosbuvir+Ledipasvir). The hepatitis C virus (HCV) -RNA level decreased to negative 4 weeks after the start of the treatment. Six weeks later, she developed ascites and showed declining hepatic spare ability.

Effect of combined farnesoid X receptor agonist and angiotensin II type 1 receptor blocker on hepatic fibrosis.

The farnesoid X receptor (FXR) agonist, a bile acid-activated nuclear receptor, has been shown to improve the histologic features of nonalcoholic steatohepatitis (NASH); however, a satisfactory effect on hepatic fibrosis has not been achieved. We aimed to investigate the combined effect of FXR agonist and angiotensin II type 1 receptor blocker on hepatic fibrogenesis in rat models of NASH. For 8 weeks, two rat models of NASH were developed.

Treatment of long-segment Barrett's adenocarcinoma by complete circular endoscopic submucosal dissection: a case report.

Background: We present the first description of en bloc endoscopic submucosal dissection (ESD) for total circumferential Barrett's adenocarcinoma, predominantly of the long-segment Barrett's esophagus (LSBE), with a 2-year follow-up and management strategies for esophageal stricture prevention.

Case Presentation: A 59-year-old man was diagnosed with LSBE and Barrett's adenocarcinoma by esophagogastroduodenoscopy (EGD). A 55-mm-long circumferential tumor was completely resected by ESD.

Serum angiotensin-converting enzyme level for evaluating significant fibrosis in chronic hepatitis B.

Aim: To evaluate the diagnostic performance of angiotensin-converting enzyme (ACE) on significant liver fibrosis in patients with chronic hepatitis B (CHB).

Methods: In total, 100 patients with CHB who underwent liver biopsy in our hospital were enrolled, and 70 patients except for 30 patients with hypertension, fatty liver or habitual alcoholic consumption were analyzed. We compared histological liver fibrosis and serum ACE levels and evaluated the predictive potential to diagnose significant liver fibrosis by comparison with several biochemical marker-based indexes such as the aspartate aminotransferase (AST)-to-platelet ratio index (APRI), the fibrosis index based on four factors (FIB-4), the Mac-2 binding protein glycosylation isomer (M2BPGi) level and the number of platelets (Plt).

Aortic Valve Replacement for the Management of Heyde Syndrome: A Case Report.

Heyde syndrome describes the triad of aortic stenosis, acquired coagulopathy, and anemia due to bleeding from intestinal angiodysplasia. An 87-year-old man with iron deficiency anemia due to melena was admitted to our hospital. On examination, a systolic murmur was heard and echocardiography confirmed the presence of aortic stenosis.

Predisposing factors for hepatocellular carcinoma recurrence following initial remission after transcatheter arterial chemoembolization.

Hepatocellular carcinoma (HCC) is prone to recurrence following curative treatment. The purpose of the present study was to identify the predisposing factors of HCC recurrence following complete remission achieved by transarterial chemoembolization (TACE). A retrospective cohort study of 70 consecutive patients with HCC who underwent TACE as the initial treatment was conducted.

A Patient with Hepatocellular Carcinoma with Isolated Right Atrial Metastases.

Hepatocellular carcinoma (HCC) with isolated right atrial metastasis is extremely rare; most cases are considered inoperable. We herein report the case of a 74-year-old man with HCC with isolated right atrial metastases without hepatic vein invasion; the right atrial lesion was resected because of the risk of heart failure and sudden death. Postoperatively, he underwent transcatheter arterial chemoembolization and radiofrequency ablation for intrahepatic HCC.
