Endoscopic retrograde cholangiopancreatography (ERCP) training remains challenging. This study used 3D printing techniques to develop and optimize a portable ERCP simulator implement basic advanced practical techniques. Subsequently, we aimed determine whether endoscopy trainees acquired proficiency in assess any improvements their skill levels from using this model. An model was generated techniques, including five distinct interchangeable transparent ampullar–common bile duct (CBD)...
Signal transducers and activators of transcription (STAT) behave as signal in the cytoplasm factors nucleus. In current study, we analyzed immunohistochemical staining patterns gastrectomy tissue specimens. We investigated expression STAT3 STAT5 estimated relationship between STAT cancer prognosis.One hundred patients who underwent due to gastric adenocarcinoma at Bundang CHA hospital January 2000 May 2005 were studied. Immunohistochemistry was carried out using antibodies against STAT5. The...
Endoscopic retrograde cholangiopancreatography (ERCP)-induced complications, once occurred, can lead to significant morbidity. Commonly 5% 10% of patients experience procedure related complications such as post-ERCP pancreatitis, biliary hemorrhage, and cholangitis, in descending order. However, perforation, pneumothorax, air embolism, splenic injury, basket impaction are rare but associated with high mortality if occurred. Such unexpected unusual might extend the length hospitalization,...
The initial 6-month data for MUSE™ (Medigus, Omer, Israel) endoscopic stapling device were reported (Zacherl et al. in Surg Endosc 29:220–229, 2015). current study aims to evaluate the long-term clinical outcome of 37 patients who received gastroesophageal reflux disease (GERD) treatment with device. Efficacy and safety analyzed at baseline, 6 months, 4 years post-procedure. In one center (IU), efficacy evaluated months post-procedure, then annually up years. No new complications have been...
This study aims to reveal more effective clinical or laboratory markers for the diagnosis of acute appendicitis and score severity based on a sufficiently large number patients with appendicitis.We identified 1,195 after excluding those other causes hyperbilirubinemia among 1,271 that underwent laparoscopic an open appendectomy between 2009 2010. A retrospective chart review medical records, including histologic results, was conducted. We then analyzed data using univariate multivariate...
OBJECTIVES: Successful biliary cannulation is a prerequisite and important component of endoscopic retrograde cholangiopancreatography, but conventional methods (CCMs) have postendoscopic cholangiopancreatography pancreatitis (PEP) rate 14.1% in patients at high risk for PEP. The aim this study was to evaluate the effectiveness safety needle-knife fistulotomy (NKF), compared with CCM, when used primary access developing METHODS: A total 207 one or more factors PEP were prospectively...
Aim Antireflux plastic biliary stents prevent duodenal reflux and improve the stent patency rate. However, efficacy of antireflux valve in a self‐expandable metal ( SEMS ) for malignant obstruction has not been well established. We evaluated with an using vitro flow studies determined impact reducing duodenobiliary on Methods In testing was conducted bile perfusion system to evaluate antegrade retrograde resistance, determine ideal shape valve. Then, prospective case series humans adequately...
This study aimed to evaluate the diagnostic role of low serum amylase and lipase values in detection chronic pancreatitis.Patients underwent endoscopic retrograde cholangiopancreatography were diagnosed with non-calcific pancreatitis (NCCP; n=99) calcific (CCP; n=112). Patient compared those healthy controls (H; n=170).The median (normal range, 19 86 U/L) (7 59 (P₂₅-P₇₅) 47.0 (39.8 55.3) 25.0 (18.0 35.0) for H, 34.0 (24.5 49.0) 19.0 (9.0 30.0) NCCP, 30.0 (20.0 40.8) 10.0 (3.0 19.0) CCP,...
Complications associated with an intramural hematoma of the bowel, is a relatively unusual condition. Most hematomas resolve spontaneously conservative treatment and patient prognosis good. However, if symptoms are not resolved or condition persists, surgical intervention may be necessary. Here we describe internal incision drainage by endoscopy for duodenum. A 63-yr-old woman was admitted to hospital hematemesis. The esophagogastroduodenoscopy (EGD) showed active ulcer bleeding at distal...
Elevated liver enzymes are observed occasionally in patients with acute cholecystitis who do not have choledocholithiasis. The etiology and mechanism of this phenomenon well known. We aimed to compare the clinical characteristics between without choledocholithiasis elevated enzymes.The medical records underwent cholecystectomy January 2001 October 2011 were retrospectively reviewed. retrieved data showed abnormal endoscopic retrograde cholangiopancreatography, magnetic resonance or...
This study compared the effects of varying lipid content and dietary concentration a lipid-encapsulated (LE) ZnO product to those native thereby find insights into optimal coating dosage Zn supplement. A total 192 21-d-old weanling pigs were allotted 48 pens, after which each six pens received ZnO-free basal diet supplemented with 125 ppm (100 Zn; BASAL), 2,500 as (HIGH), or 100 200 LE (LE-100 LE-250) containing 8%, 10%, 12% [LE-8%, LE-10%, LE-12%, respectively; 2 × 3 factorial arrangement...
Colonoscopic perforations have been managed with exploratory laparotomy, and resulted in some morbidity mortality. Recently, laparoscopic surgery is commonly performed for this purpose. The aim of study was to compare the outcomes several management strategies iatrogenic colonoscopic perforations.We retrospectively reviewed medical records patients who had treated perforation between January 2004 April 2013 at CHA Bundang Medical Center Korea.A total 41 were enrolled. Twenty underwent...
