BACKGROUND: - Conventional esophagogastroduodenoscopy is the best method for evaluation of the upper gastrointestinal tract, but it has limitations for the identification of the major duodenal papilla, even after the use of the straightening maneuver. Side-viewing duodenoscope is recommended for optimal examination of major duodenal papilla in patients at high risk for lesions in this region. OBJECTIVE: To evaluate the use of the biopsy forceps during conventional esophagogastroduodenoscopy as an additional tool to the straightening maneuver, in the evaluation of the major duodenal papilla...

Endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II patients is challenging and different endoscopes can be used. We retrospectively analysed 67 ERCP procedures in 38 Billroth II patients focussing on endoscope type and respective technical success and adverse event rate. 33 (49.2 %) ERCPs were performed using a duodenoscope, 87.9 % were successful and 3 were completed with the single-balloon enteroscope. 28 (41.8 %) ERCPs were performed with the single-balloon enteroscope, 82.1 % were successful and 2 were completed with a paediatric colonoscope...

In the present case with lower bile duct cancer, an endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) was placed because of repeated obstructions of biliary metallic stent. However, when the HGS was occluded, transpapillary duodenoscopic procedure was again required. During this transpapillary procedure, including biliary balloon cleaning and metallic stent deployment, the HGS stent was dislocated into the stomach. Fortunately, due to the complete fistulization, no bile peritonitis was recognized and an HGS stent could be replaced from the gastric wall three days later...

BACKGROUND AND AIMS: In a pilot study (8) we demonstrated that current guidelines for duodenoscope and linear echoendoscope (DLE) reprocessing using a single cycle of high-level disinfection (HLD) in an automated reprocessor may be inadequate. In August 2015, the FDA offered double-HLD as a possible response to address this concern. As a result, Providence Health & Services adopted double-HLD as standard procedure for DLE, but no rigorous clinical studies supported this practice. We undertook a quality improvement (QI) study to compare single-HLD versus double-HLD at 4 of our 34 hospitals...

BACKGROUND/AIMS: Iatrogenic infections related to duodenoscopes remain a top concern for medical centers where ERCP is performed. We assess the long-term results and the impact of key interventions in the optimization of a rigorous "culture and quarantine" program for duodenoscope reprocessing. METHODS: Review of a prospectively collected, quality assurance database of all duodenoscope cultures (N = 4307) obtained for the initial 3-year duration of culture and quarantine from 2014 to 2017 in a single U...

Background: In 2013, New Delhi metallo-β-lactamase-producing Escherichia coli, a type of carbapenem-resistant Enterobacteriaceae uncommon in the United States, was identified in a tertiary care hospital (Hospital A) in northeastern Illinois. The outbreak was traced to a contaminated duodenoscope. Patient-sharing patterns can be described through social network analysis and ego networks, which could be used to identify hospitals most likely to accept patients from a hospital with an outbreak...

OBJECTIVES: Several outbreaks of severe infections due to contamination of gastrointestinal (GI) endoscopes, mainly duodenoscopes have been described previously. The rate of microbial endoscope contamination is varying dramatically in literature. Thus, the aim of this multicentre prospective study was to evaluate the hygiene quality of endoscopes and automated endoscope reprocessors (AERs) in Tyrol/Austria. METHODS: In 2015 and 2016, a total of 463 GI endoscopes and 105 AERs from 29 endoscopy centres were analysed by a routine (R) and a combined routine and advanced (CRA) sampling procedure and investigated for microbial contamination by culture- and molecular-based analyses...

BACKGROUND: Bacterial culture is the accepted standard to measure the adequacy of high-level disinfection (HLD) of duodenoscopes. Adenosine triphosphate (ATP) bioluminescence assays have been suggested as an alternative method of evaluating the quality of reprocessing. We systematically reviewed published research describing the correlation between ATP and bacterial cultures. METHODS: The primary outcome was the correlation or concordance between concomitantly sampled ATP and bacterial contamination obtained from the instrument channel and/or elevator mechanism of the duodenoscope...

Background and study aim  Duodenoscopes have been the source of serious infection, despite correct performance of high-level disinfection (HLD). This study aimed to observe the impact of performing HLD twice on the rate of positive cultures from duodenoscope elevators. Methods  We performed double HLD (DHLD; i. e. complete manual cleaning followed by automated reprocessing, with the entire process repeated) and then randomly cultured the elevators of our duodenoscopes on about 30 % of occasions. Results  DHLD was associated with positive elevator cultures for any microorganism in 9...

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) has been proven to be a safe and effective method for diagnosis and treatment of biliary and pancreatic disorders. Major complications of ERCP include pancreatitis, hemorrhage, cholangitis, and duodenal perforation. We report a third case in literature of pneumoperitoneum after ERCP due to rupture of intrahepatic bile ducts and Glisson's capsule in a peripheral hepatic lesion. Case Report: A 50-year-old male with a history of metastatic pancreatic neuroendocrine tumor and who had a partially covered metallic stent placed in the biliary tree 1 year ago presented to the oncology clinic with fatigue, abdominal pain, and hypotension...

BACKGROUND: Prophylactic pancreatic stents after endoscopic retrograde cholangiopancreatography (ERCP) can help prevent post-ERCP pancreatitis. However most of the pancreatic stents need to be removed by another ERCP. The aim of this observational study was to investigate the feasibility and effectiveness of the modified pancreatic stent system for prevention of post-ERCP pancreatitis. METHODS: From November 2013 to November 2015, a total of 230 patients who had prophylactic pancreatic stent placed for prevention of post-ERCP pancreatitis at a single institution were identified and stratified...

The SpyGlass DS system is currently used as a direct video cholangioscope for biliary diagnostic and therapeutic procedures. In general, the SpyGlass DS cholangioscope is passed through the working channel of a duodenoscope and inserted into a bile duct via duodenal papilla. However, the procedure has been challenging in patients with altered gastrointestinal anatomy due to the retrograde route through a potentially tortuous afferent limb. A therapeutic colonoscope with variable stiffness can offer alternative guidance for SpyGlass DS cholangioscope in patients with surgically altered gastrointestinal anatomy...
