Subjective taste to polyethylene glycol is associated with efficacy of right colon preparation.

Aim: A prospective observational trial with preparations using polyethylene glycol (PEG) to compare patient compliance and adverse events according to individual subjective taste.

Methods: A total of 299 outpatients (mean ± standard deviation [SD] 56.5 ± 13.

Endoscopic retrograde cholangiopancreatography in patients with previous acute coronary syndrome.

Background/aims: Endoscopic retrograde cholangiopancreatography (ERCP) is considered a high-risk procedure in patients with previous acute coronary syndrome (ACS); however, clinical studies are rare in the literature. The aim of this study was to investigate the safety and efficacy of ERCP in patients with previous ACS.

Methods: We retrospectively reviewed the medical records of patients with previous ACS who underwent ERCP between January 2007 and August 2012.

Pretreatment antimicrobial susceptibility-guided vs. clarithromycin-based triple therapy for Helicobacter pylori eradication in a region with high rates of multiple drug resistance.

Objectives: Helicobacter pylori eradication rates with clarithromycin-based triple therapy are declining, and an alternative strategy is needed urgently. We sought to compare the efficacy of pretreatment antimicrobial susceptibility-guided vs. clarithromycin-based triple therapy for H.

Clinical outcomes of gastric variceal obliteration using N-butyl-2-cyanoacrylate in patients with acute gastric variceal hemorrhage.

Background/aims: To evaluate the long-term efficacy and safety of endoscopic injection of N-butyl-2-cyanoacrylate (NBC; Histoacryl) for treatment of bleeding gastric varices.

Methods: We retrospectively analyzed the records of 455 patients with gastric variceal hemorrhage (GVH) who were consecutively treated with NBC from January 2004 to July 2013, with a mean follow-up period of 582 days. The patients' endoscopic findings, initial hemostasis, complications, rebleeding rates, and bleeding-related death rates were reviewed.

Cap-assisted ERCP in patients with difficult cannulation due to periampullary diverticulum.

Selective biliary cannulation is an essential prerequisite for therapeutic endoscopic retrograde cholangiopancreatography (ERCP). The cap-fitted forward-viewing endoscope has been used for ERCP in patients with surgically altered anatomy. In this case series, 12 patients with periampullary diverticulum underwent ERCP using the cap-assisted forward-viewing endoscope due to failure of biliary cannulation using the standard technique.

Predictive factors for recurrence and survival in hepatocellular carcinoma in South Korea.

Aim: To evaluate the factors predicting for recurrence and to analyze survival of patients with hepatocellular carcinoma (HCC).

Patients And Methods: A total of 743 patients who were consecutively diagnosed and treated with HCC were retrospectively analyzed from January 2004 to December 2012 at our institution. We analyzed their survival and tumor recurrence.

Needle-knife fistulotomy in patients with periampullary diverticula and difficult bile duct cannulation.

Background And Aim: Needle-knife fistulotomy has commonly been used for overcoming difficult bile duct cannulation. Periampullary diverticula (PAD) can be an impediment to endoscopic retrograde cholangiopancreatography (ERCP) procedures. There are little data on needle-knife fistulotomy in patients with PAD.
