  • Deep Sedation in Advanced Endoscopy 
    Azar, Riad R.; Cote, Gregory A.; Hovis, Robert M.; Ansstas, Michael; Waldbaum, Lawrence; Edmundowicz, Steven A.; Mullady, Daniel; Jonnalagadda, Sreenivasa S. (2016-09-27)
    Background: When administered by a trained professional, the safety and efficacy of propofol in advanced endoscopy is well described. While use of propofol requires advanced airway training, it is unclear how frequently ...
  • Difficult biliary cannulation 
    Azar, Riad; Cote, Gregory A.; Ansstas, Michael; Pawa, Rishi; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa (2016-06-21)
    Background Successful cannulation of the common bile duct (CBD) remains the benchmark for ERCP. Use of a pancreatic duct (PD) stent to facilitate biliary cannulation has been described, although the majority of patients ...
  • Endoscopic treatment of pancreatic fluid collections 
    Azar, Riad; Cote, Gregory A.; Ansstas, Michael; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa; Mullady, Daniel (2016-06-23)
    Background: While successful drainage of pancreatic fluid collections (PFCs) with endoscopy is well described, the optimal algorithm for the endoscopic management of organized pancreatic necrosis (OPN) remains unclear. ...
  • Fiducial Placement for Stereotactic Radiation Using Endoscopic Ultrasound 
    Azar, Riad R.; Cote, Gregory A.; Ansstas, Michael; Parikh, Parag J.; Bradley, Jeffrey D. (2016-09-19)
    Background: Stereotactic radiation using fiducial markers permits higher doses of radiation while reducing the exposure of uninvolved, adjacent structures. Endoscopic ultrasound (EUS) has been used to deploy fiducials, ...
  • Findings at endoscopic retrograde cholangiopancreatography after endoscopic treatment of postcholecystectomy bile leaks 
    Azar, Riad; Cote, Gregory A.; Ansstas, Michael; Shah, Somal; Keswani, Rajesh N.; Alkade, Saad; Jonnalagadda, Sreenivasa; Edmundowicz, Steven A. (2016-06-22)
    Background Although the endoscopic management of bile leaks after cholecystectomy (CCY) is well established, the yield of a routine endoscopic retrograde cholangiogram (ERC) with a bile duct sweep at the time of stent ...
  • Physician Controlled Wire Guided Cannulation of the Minor Papilla 
    Azar, Riad R.; Ammar, Tarek; Maple, John T.; Ansstas, Michael; Abdeen, Basem M.; Cote, Gregory A. (2016-09-20)
    Objective: Cannulation of the minor papilla (MiP) can be challenging. Historically, specialty accessories and small caliber guidewires have been advocated for approaching the MiP. New short-wire ERCP platforms allow ...
  • Physician-Controlled Wire-Guided Cannulation of the Minor Papilla 
    Azar, Riad R.; Maple, John T.; Mansour, Lilah; Ammar, Tarek; Ansstas, Michael; Coté, Gregory A. (2016-09-20)
    Background. Minor papilla (MiP) cannulation is frequently performed using specialized small-caliber accessories. Outcomes data for MiP cannulation with standard-sized accessories are lacking. Methods. This is a case series ...
  • A randomized clinical trial comparing the use of a pancreatic duct stent or a pancreatic duct guidewire to facilitate bile duct cannulation 
    Azar, Riad; Cote, Gregory A.; Hovis, Christine E.; Keswani, Rajesh N.; Ansstas, Michael; Edmundowicz, Steven A. (2016-06-23)
    Among cases of difficult biliary cannulation, alternatives to precut sphincterotomy include use of a pancreatic duct (PD) stent (PDS) or guidewire (PDW) to facilitate common bile duct cannulation (CBDC). We present the ...
  • Risk of post-ERCP pancreatitis with placement of self-expandable metallic stents 
    Azar, Riad R.; Cote, Gregory A.; Kumar, Nitin; Ansstas, Michael; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa (2016-06-21)
    Background: There are conflicting data on the risk of post-ERCP pancreatitis (PEP) related to self-expandable metallic stents (SEMSs). Objective: To compare rates of PEP in patients who undergo biliary drainage with SEMSs ...
  • Risk of post-ERCP pancreatitis with placement of self-expandable metallic stents 
    Azar, Riad R.; Cote, Gregory A.; Ansstas, Michael; Kumar, Nitin; Reinink, Andrew; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa; Mullady, Daniel (2016-09-26)
    Background: For malignant biliary obstruction (MBO), self-expandable metallic stents (SEMS) provide greater durability compared to plastic stents (PS). Previous studies have raised the possibility of higher rates of post-ERCP ...
