Current Status of Diagnosis and Treatment of Colorectal Cancer in Asian Countries: A Questionnaire Survey.

Introduction: Diagnostic and therapeutic methods for colorectal cancer (CRC) have advanced; however, they may be inaccessible worldwide, and their widespread use is challenging. This questionnaire survey investigates the current status of diagnosis and treatment of early-stage CRC in Asian countries.

Methods: Responses to the questionnaire were obtained from 213 doctors at different institutions in 8 countries and regions.

Role of oral iron supplementation for anemia secondary to acute nonvariceal upper gastrointestinal bleeding: a randomized controlled trial.

Background And Aim: Although acute upper gastrointestinal bleeding (UGIB) can lead to anemia, evidence regarding the effects of oral iron supplementation on UGIB-induced anemia following discharge remains lacking. The present study aimed to investigate the effects of oral iron supplementation on hemoglobin response and iron storage in patients with anemia secondary to nonvariceal UGIB.

Methods: This randomized controlled trial included 151 patients with nonvariceal UGIB who had anemia at discharge.

Effect of holiday admission on clinical outcome of patients with upper gastrointestinal bleeding: A real-world report from Thailand.

Background: Holiday admissions are associated with poorer clinical outcomes compared with non-holiday admissions. However, data remain inconsistent concerning the "holiday effect" for patients with upper gastrointestinal bleeding. This study compared the differences between clinical courses of patients with upper gastrointestinal bleeding who were admitted on holidays and non-holidays in Thailand.

Impact of alcohol consumption on treatment outcome of hepatocellular carcinoma patients with viral hepatitis who underwent transarterial chemoembolization.

Background: Alcohol consumption increases the risk of hepatocellular carcinoma (HCC) in patients with pre-existing liver disease, including viral hepatitis. However, studies on the impact of alcohol consumption on the outcomes of HCC are limited. We hypothesized that alcohol had an additional effect with chronic viral hepatitis infection on treatment outcomes after transarterial chemoembolization (TACE) in patients with intermediate-stage HCC (Barcelona Clinical Liver Cancer [BCLC] -B).

Comparison of blue laser imaging and narrow band imaging for the differentiation of diminutive colorectal polyps: A randomized controlled trial.

Background: To compare the diagnostic efficacy of blue laser imaging (BLI)- bright and narrow band imaging (NBI) modes of image enhanced endoscopy (IEE) in differentiating neoplastic and non-neoplastic lesions of diminutive colorectal polyps.

Methods: We conducted a prospective randomized controlled trial from September 2015 to July 2016. The participants were randomly assigned (1:1) for colonoscopy with polyp classification under NBI or BLI-bright mode without magnification.

Continuous Infusion of Fluid Hydration Over 24 Hours Does Not Prevent Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis.

Background: Aggressive intravenous fluid hydration, by administering 3500 mL of lactated Ringer's solution (LRS) in 9 h with a peri-procedural bolus, reduces post-ERCP pancreatitis (PEP) incidence. A concern of this strategy is adverse events related to volume overload; however, the impact of fluid hydration over an extended period without a bolus on PEP is unknown.

Aim: To assess the effect of continuous infusion of high-volume fluid at a constant rate over 24 h on PEP incidence and severity.

Diagnostic power of DNA methylation markers suggestive of cholangiocarcinoma in ERCP-based brush cytology.

Background And Aims: Accurate differentiation between cholangiocarcinoma (CCA) and benign biliary stricture is of paramount importance. Biliary brush cytology is a simple and safe diagnostic approach that provides relatively high specificity; however, sensitivity is limited. Previous reports indicated the aberrations of DNA methylation in CCA.

Pancreaticopleural fistula in a child with chronic pancreatitis harboring compound SPINK1 variants.

Background: Pancreaticopleural fistula (PPF) is a rare complication of chronic pancreatitis (CP) that requires a high index of clinical suspicion in the patient who presents with a pleural effusion. Visualizing the fistula tract from the pancreatic duct to the pleural space by radiological imaging provides confirmation of this complication.

Case Presentation: A 9-year-old boy who presented with massive right pleural effusion secondary to PPF, a complication of CP from a genetic mutation involving two mutations of SPINK1.

Efficacy and safety of EUS-guided hepaticoesophagostomy (EUS-HES) for malignant biliary obstruction: the first case series.

Background: EUS-guided hepaticoesophagostomy (EUS-HES) was reported as an alternative procedure when puncture through the esophagus was inevitable. However, the existing data is very limited. We aimed to evaluate the efficacy and safety of EUS-HES in patients with difficult malignant biliary obstruction.

Immunoglobulin G4-associated autoimmune hepatitis with peripheral blood eosinophilia: a case report.

Background: Immunoglobulin G4 (IgG4) associated autoimmune hepatitis (AIH) has been recognized as a type of autoimmune disease that responds to corticosteroid. The diagnosis is based on elevation of the serum IgG4 level, abundance of IgG4 enhanced plasma cell infiltration in the portal region of the liver, and satisfaction of the criteria for "definite AIH" under the revised International Autoimmune Hepatitis Group (IAIHG) scoring system. However, the clinical course of the disease is unclear.

Prospective Comparison of the AIMS65 Score, Glasgow-Blatchford Score, and Rockall Score for Predicting Clinical Outcomes in Patients with Variceal and Nonvariceal Upper Gastrointestinal Bleeding.

Background/aims: This study aimed to determine the performance of the AIMS65 score (AIMS65), Glasgow-Blatchford score (GBS), and Rockall score (RS) in predicting outcomes in patients with upper gastrointestinal bleeding (UGIB), and to compare the results between patients with nonvariceal UGIB (NVUGIB) and those with variceal UGIB (VUGIB).

Methods: We conducted a prospective observational study between March 2016 and December 2017. Receiver operating characteristic curve analysis was performed for all outcomes for comparison.

Correction to: Comparison of Clinical Outcomes Between Surgical Gastrostomy and Percutaneous Endoscopic Gastrostomy with Introducer Technique in Patients with Upper Aerodigestive Malignancies: A Single-Center Analysis.

In the original version of this article, there were data missing from Table 3. Following is the corrected table. The original article has been updated.

Comparison of Clinical Outcomes Between Surgical Gastrostomy and Percutaneous Endoscopic Gastrostomy with Introducer Technique in Patients with Upper Aerodigestive Malignancies: A Single-Center Analysis.

Background: Conventional percutaneous endoscopic gastrostomy (PEG) in patients with upper aerodigestive malignancies inevitably carries a risk of stomal metastasis that could be avoided by the direct insertion of the gastrostomy tube through the abdomen. This study compared the efficacy and safety between surgical gastrostomy (SG) and Introducer PEG in patients with upper aerodigestive malignancies.

Methods: We retrospectively reviewed patients with upper aerodigestive malignancies undergoing SG or Introducer PEG.

Endoscopic Management of a Proximally Migrated Fully Covered SEMS Using the Stent-in-Stent Technique.

Endoscopic biliary decompression stent placement is an important approach for the palliative management of distal malignant biliary obstruction. However, migration of the inserted stent can occur, either distally or proximally; proximal migration is less common, but it also presents a greater challenge for endoscopic resolution. We present a case of a 67-year-old woman who had locally advanced pancreatic cancer and developed a common bile duct obstruction.

DNA Methylation Markers Improve the Sensitivity of Endoscopic Retrograde Cholangiopancreatography-Based Brushing Cytology in Extrahepatic Cholangiocarcinoma.

Endoscopic retrograde cholangiopancreatography with brushed cytology is still the standard method for the diagnosis of extrahepatic cholangiocarcinoma in obstructive jaundice; however, the diagnostic yield is limited. To improve the diagnostic sensitivity, DNA methylation analysis is an attractive candidate, since this may constitute a stable marker in brushed specimens. Therefore, this study aims to evaluate the importance of such epigenetic markers in brushed biliary cells from patients with obstructive jaundice for the diagnosis of extrahepatic cholangiocarcinoma.

Plasma Lipidomics as a Tool for Diagnosis of Extrahepatic Cholangiocarcinoma in Biliary Strictures: a Pilot Study.

Biliary obstruction is a common clinical manifestation of various conditions, including extrahepatic cholangiocarcinoma. However, a screening test for diagnosis of extrahepatic cholangiocarcinoma in patients with biliary obstruction is not yet available. According to the rationale that the biliary system plays a major role in lipid metabolism, biliary obstruction may interfere with lipid profiles in the body.

Chronic pancreatic pain successfully treated by endoscopic ultrasound-guided pancreaticogastrostomy using fully covered self-expandable metallic stent.

One of the most common symptoms presenting in patients with chronic pancreatitis is pancreatic-type pain. Obstruction of the main pancreatic duct in chronic pancreatitis can be treated by a multitude of therapeutic approaches, ranging from pharmacologic, endoscopic and radiologic treatments to surgical interventions. When the conservative treatment approaches fail to resolve symptomatic cases, however, endoscopic retrograde pancreatography with pancreatic duct drainage is the preferred second approach, despite its well-recognized drawbacks.

Endoscopic ultrasound-guided interventions in special situations.

Endoscopic ultrasound (EUS) was introduced in 1982 and has since become a popular advanced procedure for diagnosis and therapeutic intervention. Initially, EUS was most commonly used for the diagnosis of pancreatobiliary diseases and tissue acquisition. EUS was first used for guided cholangiography in 1996, followed by EUS-guided biliary drainage in 2001.

Clinical, Radiologic, and Endoscopic Manifestations of Small Bowel Malignancies: a First Report from Thailand.

Background: The symptoms of small bowel malignancies are mild and frequently nonspecific, thus patients are often not diagnosed until the disease is at an advanced stage. Moreover, the lack of sufficient studies and available data on small bowel cancer makes diagnosis difficult, further delaying proper treatment for these patients. In fact, only a small number of published studies exist, and there are no studies specific to Thailand.

Mediastinal small cell carcinoma with liver and bone marrow metastasis, mimicking lymphoma.

Primary mediastinal neuroendocrine tumors are a rare malignancy that accounts for < 10% of all mediastinal tumors. The case presented here involves a 52-year-old man who had been suffering for 3 mo from chronic cough, anorexia and substantial weight loss, as well as 2 wk of jaundice prior to his admission. A computed tomography scan showed a 4.

Endoscopic ultrasound-guided biliary drainage: Bilateral systems drainage via left duct approach.

Endoscopic ultrasound (EUS)-guided biliary drainage is accepted as a less invasive, alternative treatment for patients in whom endoscopic retrograde cholangiopancreatography has failed. Most patients with malignant hilar obstruction undergo EUS-guided hepaticogastrostomy. The authors present the case of a 77-year-old man with advanced hilar cholangiocarcinoma who had undergone a roux-en-Y hepaticojejunostomy several months prior.
