BACKGROUND Rectal indometacin decreases the occurrence of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). However, the population most at risk and the optimal timing of administration require further investigation. We aimed to assess whether pre-procedural administration of rectal indometacin in all patients is more effective than(More)
BACKGROUND Air cholangiogram has been used in patients with malignant hilar obstruction to reduce cholangitis after endoscopic retrograde cholangiopancreatography (ERCP). However, it still remains unclear whether CO2 could be used as an alternative for air cholangiography in such patients. OBJECTIVE To investigate the effect of CO2 cholangiogram on(More)
BACKGROUND A new polysaccharide hemostatic system (EndoClot(TM) ) was recently developed for bleeding control in gastrointestinal tract endoscopy; however, its efficacy and safety is not yet well established in colorectal endoscopic mucosal resection (EMR). The aim of the present study was to observe the bleeding control effect after EMR in the colorectum.(More)
BACKGROUND Stone recurrence is a common late adverse event after ERCP in patients with common bile duct stones (CBDS). Duodenal-biliary reflux (DBR) is considered a major cause of CBDS recurrence. However, specific evidence is still lacking. OBJECTIVE To investigate the DBR rate in patients with recurrent CBDS after ERCP. DESIGN A prospective(More)
BACKGROUND Plastic and covered metal stents need to be removed or exchanged within appropriate time in case of undesirable complications. However, it is not uncommon that patients do not follow the recommendation for further stent management after Endoscopic Retrograde Cholangiopancreatography (ERCP). The effect of short message service (SMS) intervention(More)
BACKGROUND AND STUDY AIM The allocation of sufficient time for trainees to attempt cannulation is necessary for learning and to ensure success with endoscopic retrograde cholangiopancreatography (ERCP) training. However, it is important to balance the benefit to trainee practice against the potential risks to patients. The appropriate time for attempted(More)
BACKGROUND Online social networking is increasingly being used among medical practitioners. However, few studies have evaluated its use in therapeutic endoscopy. Here, we aimed to analyze the shared topics and activities of a group of endoscopic retrograde cholangiopancreatography (ERCP) doctors in a social networking-based endoscopic retrograde(More)
OBJECTIVE To evaluate the performance of trainees after finishing hands-on training of endoscopic retrograde cholangiopancreatography (ERCP) at our hospital. METHODS Questionnaire was distributed to 46 trainees of ERCP training over the past 5 years. And the effects of training duration, case volume and hospital facilities on ERCP performance were(More)
