The relationship between hiatal hernias and gastroesophageal reflux disease (GERD) has been greatly debated over the past decades, with the importance of hiatal hernias first being overemphasized and then later being nearly neglected. It is now understood that both the anatomical (hiatal hernia) and the physiological (lower esophageal sphincter) features of the gastroesophageal junction play important, but independent, roles in the pathogenesis of GERD, constituting the widely accepted "two-sphi

Acute pancreatitis is an inflammatory disease characterized by interstitial edema, inflammatory cell infiltration, and acinar cell necrosis, depending on its severity. Regardless of the extent of tissue injury, acute pancreatitis is a completely reversible process with evident normal tissue architecture after recovery. Its pathogenic mechanism has been known to be closely related to intracellular digestive enzyme activation. In contrast to acute pancreatitis, chronic pancreatitis is characterize

OBJECTIVE: Submucosal injection is used to prevent complications, such as perforation, during endoscopic mucosal resection (EMR). Since injection of normal saline produces mucosal elevation of short duration, repeated injection is needed for extensive resection. To overcome this limitation, various submucosal injection solutions have been developed but there are few data comparing their efficacy. This study was therefore conducted to compare the physical and chemical properties and the duration

Eradication therapy may be offered as an initial treatment option even in cases of localized H. pylori-negative gastric MALT lymphoma.

Endoscopic variceal band ligation (EVL) is an effective procedure to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. Several studies have reported that proton pump inhibitors (PPIs) decrease the size of post-EVL ulcers. However, evidence are limited as to whether PPIs actually reduce the risk of bleeding after EVL. This study aimed to analyze the factors associated with bleeding after prophylactic EVL and to asse

BACKGROUND: Suppression of hepatitis B virus (HBV) DNA is more potent, and occurrence of resistant strain is rare with entecavir than lamivudine, but whether these merits result in a more favourable outcome in HBV-related decompensated cirrhosis patients is unclear. AIMS: To compare virologic response, changes in liver function, clinical course and predictive factors for early mortality after treatment between patients treated with lamivudine and those with entecavir in HBV-related decompensated

Magnesium trihydrate of UDCA and CDCA is a well-tolerated bile acid that showed similar efficacy for gallstone dissolution and improvement of gallstone-related symptoms as that shown in previous studies.

This study confirms that infected WON has worse outcomes than sterile WON but also demonstrates that WON, once considered a significant cause of death, can be treated with good outcomes using minimally invasive therapy.

BACKGROUND AND OBJECTIVES: Unlike pancreatic head tumors, little is known about the biological significance of radiographic vessel involvement with pancreatic body/tail adenocarcinoma. We hypothesized radiographic splenic vessel involvement may be an adverse prognostic factor. METHODS: All distal pancreatectomies performed for resectable pancreatic adenocarcinoma between 2000 and 2016 were reviewed and clinicopatholgic data were collected, retrospectively. Preoperative computed tomography imagin

Purpose: Hepatitis B virus (HBV) infection and metabolic syndrome (MS) are known independent risk factors for hepatocellular carcinoma (HCC) and other extrahepatic organ malignancies. The purpose of this study was to investigate whether MS and HBV have synergistic effects on cancers and to examine whether increasing the number of MS components could lead to higher risk of cancer development. Materials and Methods: We evaluated data from 1,504,880 HBV-infected adults who underwent a regular HCC s

Terlipressin is a splanchnic constrictor that is used to control variceal bleeding and is considered to have a very good safety profile compared to vasopressin. However, side effects such as hyponatremia and seizure, although very rare, can occur. Recently, the authors have experienced a case of hyponatremia induced by infusion of terlipressin which resulted in generalized seizure. On admission, the patient's sodium level was 141 mmol/l but, 4 days after the initiation of terlipressin, it plumme

BACKGROUND/AIMS: The nonspecific clinical presentation of acute hepatitis A (AHA) mandates the detection of anti-hepatitis A virus IgM antibodies (IgM anti-HAV) in the serum for obtaining a definitive diagnosis. However, IgM anti-HAV might not be present during the early phase of the disease. The aim of this study was to determine the optimal time for repeating the IgM anti-HAV test (HAV test) in AHA patients with a negative initial test. METHODS: In total, 261 patients hospitalized with AHA wer

Modulation of HSP 70 expression with quercetin enhanced the chemoresponsiveness of PCCs to gemcitabine. The mechanism of cell death was both apoptosis and autophagy.
