Comparison of local recurrence in transcatheter arterial chemoembolization of hepatocellular carcinoma with or without accumulation of iodized oil beyond corona enhancement area: Short-term results.

Background: Local tumor recurrence of hepatocellular carcinoma (HCC) often occurs in blood drainage areas. Corona enhancement is determined by computed tomography during hepatic arteriography (CTHA) and is considered to represent the blood drainage area. This study aimed to investigate the relationship between embolization of corona enhancement area and local tumor recurrence of patients with HCC who underwent transcatheter arterial chemoembolization (TACE).

Upon abdominal ultrasonography, a woman in her 36 years old was diagnosed with a hypoechoic tumor with a diameter of 60mm surrounding the bile duct in the hepatic portal region. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed a tumor-like mass in the bile duct. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) confirmed the diagnosis of schwannoma.

Quantitative Ultrasound Image Analysis Helps in the Differentiation of Hepatocellular Carcinoma (HCC) From Borderline Lesions and Predicting the Histologic Grade of HCC and Microvascular Invasion.

Objectives: Quantitative image analysis is one of the methods to overcome the lack of objectivity of ultrasound (US). The aim of this study was to clarify the correlation between the features from a US image analysis and the histologic grade and microvascular invasion (MVI) of hepatocellular carcinoma (HCC) and differentiation of HCC smaller than 2 cm from borderline lesions.

Methods: We retrospectively analyzed grayscale US images with histopathologic evidence of HCC or a precancerous lesion using ImageJ version 1.

The influence of esophagogastroduodenoscopy using carbon dioxide insufflation on abdominal ultrasonographic imaging efficiency.

Purpose: The ability to perform abdominal ultrasonography after esophagogastroduodenoscopy (EGD) is hypothesized to improve examination efficiency. Therefore, we performed abdominal ultrasonography before and after EGD to verify the effects of EGD on abdominal ultrasonographic imaging efficiency.

Methods: We performed abdominal ultrasonography before, immediately after, 30 min after, and 60 min after EGD with carbon dioxide (CO) insufflation in 23 consecutive patients who visited our center between July 2015 and December 2016.

Functional Analysis of Human Hepatocytes Isolated From Chimeric Mouse Liver.

Chimeric mice with humanized liver were first established by transplanting primary human hepatocytes (PHHs) isolated from a Japanese 27-year-old donor into complementary DNA-urokinase-type plasminogen activator/severe combined immunodeficiency mice. The PHHs from the Japanese donor increased more than 100-fold in the mouse liver, and human hepatocytes purified from the chimeric mouse liver (hcPHs) were successfully transplanted into second-passaged mice. These PHHs and hcPHs can produce human albumin and preserve many liver-specific enzyme genes, which are important for liver function.

Spontaneous Development of Acute Obstructive Suppurative Pancreatic Ductitis Associated with Pancreatic Carcinoma: A First Case Report.

Abdominal computed tomography revealed a suspicious tumor in the body of the pancreas, along with a dilated main pancreatic duct and edema of the pancreatic tail. Endoscopic retrograde pancreatography was performed after treating the patient's pancreatitis.

Severe Hypertriglyceridemia Possibly Masked Acute Pancreatitis and Led to a Difficult Diagnosis in an Obese Patient with Ketoacidosis-onset Type 2 Diabetes.

A young obese man with ketoacidosis-onset type 2 diabetes mellitus, associated with severe hypertriglyceridemia, was admitted to a local hospital complaining of abdominal pain. Although the abdominal pain worsened, his serum amylase level remained normal with persistent severe hypertriglyceridemia until the second day of hospitalization. The next day, computed tomography showed severe acute pancreatitis (AP) with serum amylase elevation, while the patient's triglyceride level decreased to 558 mg/dL.

Location of the meso-pancreatoduodenum as a regional lymphatic basin for pancreatic head carcinoma.

The meso-pancreatoduodenum is the primary site of tumor infiltration in patients with pancreatic head cancer, with numerous patients exhibiting lymph node metastases. Effective dissection of the regional lymphatic basin requires knowledge of the patterns of the arterial branches. The present study examined the patterns of the arteries feeding the pancreatic head and the distribution of the meso-pancreatoduodenum.

Renal vein dilation predicts poor outcome in patients with refractory cirrhotic ascites.

Aim: Renal venous hypertension is known to be associated with worsening of renal function in patients with decompensated heart failure. Intra-abdominal hypertension including cirrhotic ascites also leads to renal venous hypertension. We aimed to clarify the effect of renal venous hypertension on cirrhotic ascites.

Neoadjuvant chemotherapy for pancreatic cancer: Effects on cancer tissue and novel perspectives.

Chemotherapy for pancreatic cancer has diversified following the addition of more treatment regimens; however, in spite of this, pancreatic cancer remains a fatal disease. Preoperative (neoadjuvant) chemotherapy (NAC) or neoadjuvant chemoradiation therapy (NACRT) has been developed and implemented. For patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC), a number of clinical trials have been conducted; NACRT was demonstrated to improve resectability, R0 resection rate, overall survival rate, disease-free survival rate and even an LAPC and BRPC survival advantage over NAC.

Solitary Variceal Rupture in the Small Intestine.

A 70-year-old man was referred to our hospital to undergo treatment for hepatocellular carcinoma. In hospital, he complained of hematochezia and a laboratory analysis revealed a decreased level of hemoglobin. Abdominal computed tomography revealed a tumor in the small intestine, with slow enhancement of the dorsal region.

Expression status of CD44 and CD133 as a prognostic marker in esophageal squamous cell carcinoma treated with neoadjuvant chemotherapy followed by radical esophagectomy.

Cancer stem cells (CSCs) have self-renewal and pluripotency capabilities and contribute to cancer progression and chemoresistance. It has been proposed that the treatment resistance and heterogeneity of CSCs are deeply involved in the prognosis of patients with esophageal squamous cell carcinoma (ESCC). The objective of this study was to identify the influence of the expression status of the CSC markers CD44 and CD133 on chemotherapeutic efficacy and prognosis in ESCC patients who underwent radical esophagectomy after neoadjuvant chemotherapy (NAC).

Contrast-enhanced ultrasonographic findings of serum amyloid A-positive hepatocellular neoplasm: Does hepatocellular adenoma arise in cirrhotic liver?

Hepatocellular adenoma (HCA) was recently classified into four pathological subtypes. There have been few studies describing the findings of contrast-enhanced ultrasonography (CEUS) of each type. Our case concerns a 78-year-old man who had undergone routine medical check-ups for hepatitis C for 11 years.

Ischemia reperfusion-facilitated sinusoidal endothelial cell injury in liver transplantation and the resulting impact of extravasated platelet aggregation.

Background: The exact sequence of events leading to ultimate hepatocellular damage following ischemia/reperfusion (I/R) is incompletely understood. In this article, we review a mechanism of organ dysfunction after hepatic I/R or immunosuppressive treatment, in addition to the potential of liver sinusoidal endothelial cell (LSEC) protection and antiplatelet treatment for the suppression of hepatocellular damage.

Methods: A review of the literature, utilizing PubMed-NCBI, was used to provide information on the components necessary for the development of hepatocellular damage following I/R.

Technique of Transbrachial Angiography and Treatment for Abdominal Diseases: A Study of 6262 Patients.

For over 20 years, we have been using the transbrachial approach as the first-line option for abdominal angiography and transcatheter arterial chemoembolization (TACE). The present study involving 6262 patients (success rate of 99.8%) showed that the transbrachial approach could be used for superselective angiography or computed tomography during angiography (angio-CT) and was effective for hemostasis of abdominal aneurysmal hemorrhage, diverticular hemorrhage and partial splenic embolization.

A case of miriplatin-induced lung injury.

A 69-year-old man with an 8-year history of hepatocellular carcinoma (HCC) was hospitalized for treatment of recurrent tumour. In 2010, the first transcatheter arterial chemoembolization (TACE) using miriplatin with agents (Lipiodol Ultra-Fluid) was performed and did not occur any adverse events. In 2014, since his HCC recurred, the TACE using miriplatin with agents was performed.

Liver resection and partial pneumonectomy were performed.

Postoperative neutrophil-to-lymphocyte ratio of living-donor liver transplant: Association with graft size.

Issues related to small-for-size grafts in living donor liver transplantation (LDLT) are highly important. The neutrophil lymphocyte ratio (NLR) has been reported to be an inexpensive index of systemic inflammation for various diseases. We retrospectively evaluated the relationship between NLR and clinical course of 61 adult LDLT recipients in our institute until post-operative day 14.

Concentration-dependent radiosensitizing effect of docetaxel in esophageal squamous cell carcinoma cells.

Taxanes, paclitaxel and docetaxel (DTX) are anticancer agents that exhibit cytotoxicity by inhibiting microtubule polymerization. They enhance the radiosensitivity of various cancers by blocking the cell cycle in the most radiosensitive G2/M phase. Recently, taxanes have been reported to have different mechanisms of action depending on dose intensity.

Extravasated Platelet Aggregation in Liver Zone 3 Is Associated With Thrombocytopenia and Deterioration of Graft Function After Living-Donor Liver Transplant.

Objectives: Continuous thrombocytopenia after liver transplant is associated with a less favorable prognosis, but this pathogenesis remains unclear. We focused on the consumption of platelets in the allograft. We assessed platelet consumption in allografts, and evaluated the pathology of platelet aggregation in an allograft tissue and its involvement in clinical outcomes.

[A case of acute progressive primary inflammatory fibrosarcoma of the retroperitoneum].
