Prediction model for non-curative resection of endoscopic submucosal dissection in patients with early gastric cancer.

Background And Aims: Endoscopic submucosal dissection (ESD) is a useful method for complete resection of early gastric cancer (EGC). However, there are still some patients who undergo additional gastrectomy after ESD because of non-curative resection. There is no model that can accurately predict non-curative resection of ESD.

Safety and feasibility of simultaneous endoscopic submucosal dissection for multiple gastric neoplasias.

Background: Synchronous gastric neoplasms are not infrequently detected, thus endoscopic submucosal dissection (ESD) for multiple early gastric neoplasia is occasionally considered. However, there have been few investigations of the safety and feasibility of simultaneous ESD for multiple gastric lesions. This study aims to evaluate the safety and feasibility of simultaneous ESD for multiple gastric neoplasia.

Ventricular tachyarrhythmias in a patient with Andersen-Tawil syndrome.

Andersen-Tawill syndrome (ATS), a rare autosomal dominant disorder, is characterized by periodic paralysis, dysmorphic features and cardiac arrhythmias. This syndrome is caused by mutations of KCNJ2 gene, which encodes inward rectifying potassium channel. Here, we report an 18-year-old girl who was presented with life-threatening cardiac arrhythmia and acute respiratory distress.

Sedation methods can determine performance of endoscopic submucosal dissection in patients with gastric neoplasia.

Background: Although proper sedation is mandatory for endoscopic procedures such as endoscopic submucosal dissection (ESD), there is no research investigating the effects of sedation on ESD performance and complications. We aimed to evaluate the relationship among sedation methods, clinical outcomes, and complications after ESD for gastric neoplasia.

Methods: We retrospectively reviewed clinical data of 1,367 patients with 1,485 lesions who had undergone ESD for gastric adenoma or early gastric cancer at our tertiary teaching hospital in Seoul, Korea, between January 2008 and May 2011.

Prospective validation of FibroTest in comparison with liver stiffness for predicting liver fibrosis in Asian subjects with chronic hepatitis B.

Background And Aims: Diagnostic values of FibroTest (FT) for hepatic fibrosis have rarely been assessed in Asian chronic hepatitis B (CHB) patients. We aimed to validate its diagnostic performances in comparison with liver stiffness (LS).

Methods: From 2008 to 2010, 194 CHB patients who underwent liver biopsies along with FT and transient elastography were prospectively enrolled.

A case of hepatocellular carcinoma in the caudate lobe successfully treated by transcatheter arterial chemoembolization using drug-eluting beads.

Hepatocellular carcinoma (HCC) in the caudate lobe remains one of the most intricate locations where various treatments tend to pose problems with regard to the optimal approach. Surgical resection has been regarded as the most effective treatment; however, isolated resection of the caudate lobe is strenuous and associated with a high rate of early recurrence. Percutaneous ablation might be technically difficult or impossible to perform due to the deep location of tumors and adjacent large vessels.
