In contrast to uncovered biliary SEMSs, in most cases malfunctioning covered biliary SEMSs can be easily and safely removed endoscopically using a rat-tooth forceps.

KCS score may be clinically simple and useful for assessing advanced neoplasia risk in Korea. However, racial disparity should be considered in risk stratification-based screening in each country.

Higher SUVmax of primary pancreatic tumor is associated with poor PFS and pretreatment SUVmax is an independent prognostic factor for predicting PFS in patients with locally advanced or metastatic pancreatic cancer who received gemcitabine-based palliative chemotherapy. However, pretreatment SUVmax is not associated with chemotherapeutic response.

SOF-based regimens resulted in high SVR12 rates in patients with moderately impaired renal function. During therapy, HCV patients with CKD should be carefully monitored for worsening renal function.

Both ETV and TDF therapy resulted in a high CVR, and the annual incidence rates of HCC and other cirrhosis-related complications were not significantly different between the two treatment groups.

Our results suggest that KRG has antioxidant therapeutic effects on superoxide dismutase inhibitor-induced pancreatitis by inhibition of nuclear factor kappaB.

A leukemoid reaction is defined as reactive leukocytosis exceeding 50,000/mm(3), with a significant increase in early neutrophil precursors, and can be a paraneoplastic manifestation of various malignant tumors. A 71-year-old male patient complained of decreased appetite, fatigue, and abdominal fullness. He had a palpable, firm liver, and laboratory investigations suggested leukemoid reaction. Liver dynamic computed tomography revealed a hypervascular mass, and an ultrasound-guided fine-needle a

Backgound and Objectives: The treatments of choice for patients with early-stage hepatocellular carcinoma (HCC) are surgical resection, local ablation therapy, and liver transplantation; however, transarterial chemoembolization (TACE) is commonly performed due to variations among patients and liver diseases. This study aimed to assess the efficacy of TACE in patients with early-stage HCC. Materials and Methods: A retrospective analysis was performed of all TACE procedures performed at Kyung Hee

Untreated benign biliary stricture can lead to serious complications including recurrent cholangitis, biliary cirrhosis, hepatic failure, and death. Benign stricture of a postoperative anastomosis site is also a problematic issue after biliary surgery. Percutaneous transhepatic cholangioscopy (PTCS) with balloon dilatation is a recently introduced noninvasive therapeutic option for biliary stricture. Guidewire insertion through the stricture site is essential for the success of PTCS treatment. R

GOALS: This study sought to clarify sex differences in KRAS mutations and clinical predictors of KRAS 13 codon mutations. BACKGROUND: Sex differences in KRAS mutations and predictors for KRAS codon 13 mutations in colorectal cancer (CRC) are unclear. STUDY: Between October 2007 and May 2016, 328 patients underwent surgery for CRCs that were analyzed for KRAS mutations at a referral university hospital. Sex differences in the rates and distributions of KRAS mutations, and factors predictive of ov

Endoscopic resection (ER) is an effective treatment for early gastric cancer (EGC) without metastases. Existing endoscopic mucosal resec-tion (EMR) is easy to perform, has few complications, and can be ap-plied when the lesion size is small. However, <i>en bloc</i> and complete re-section rates vary depending on the size and severity of the lesion. EMR using the cap-mounted panendoscopic method and EMR after circum-ferential preamputation of the lesion are useful in the treatment of

In this single-center, real-world setting, the treatment of chronic HCV G1 resulted in a high rate of SVR, especially in patients without cirrhosis.
