  • Carbon Dioxide (CO2) Insufflation during ERCP for the Reduction of Post-procedure Pain 
    Azar, Riad R.; Keswani, Rajesh N.; Hovis, Robert M.; Edmundowicz, Steven A.; Sadeddin, Esmat Z.; Jonnalagadda, Sreenivasa S.; Waldbaum, Lawrence; Maple, John T. (2016-10-10)
    Background: Abdominal pain and nausea following ERCP are common, and may in part relate to bowel insufflation with air. CO2 insufflation during colonoscopy reduces post-procedural pain scores as compared with air. However, ...
  • Carbon dioxide insufflation during ERCP for reduction of postprocedure pain 
    Azar, Riad; Maple, John T.; Keswani, Rajesh N.; Hovis, R. Mark; Saddedin, Esmat Z.; Jonnalagadda, Sreenivasa (2016-06-21)
    Background: Abdominal pain after ERCP is common, and although it is frequently nonspecific and self-limited, it may provoke concern for complications and thus distress both patients and physicians. Carbon dioxide (CO2) ...
  • Compliance with surveillance recommendations for foregut subepithelial tumors is poor 
    Azar, Riad R.; Kushnir, Vladimir M.; Keswani, Rajesh N.; Hollander, Thomas G.; Kohlmeier, Cara; Mullady, Daniel K.; Murad, Faris M.; Komanduri, Srinadh; Edmundowicz, Steven A.; Early, Dayna S. (2016-09-28)
    Background American Gastroenterological Association guidelines recommend performing EUS to characterize subepithelial lesions (SELs) discovered on upper endoscopy (EGD), followed by surveillance if no high-risk features ...
  • 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 ...
  • Learning curves for Endoscopic Ultrasonography (EUS) Using Cumulative Sum (CUSUM) Analysis 
    Azar, Riad; Wani, Sachin; Keswani, Rajesh N.; Mullady, Daniel; Murad, Faris; Edmundowicz, Steven A. (2016-06-23)
    The guidelines set forth by ASGE for assessing minimal competence in EUS are based on expert opinions and retrospective studies. Prospective data are needed to help guide development of evidence-based training guidelines.
  • A prospective multicenter EUS database of subepithelial gastric lesions 
    Azar, Riad R.; Early, Dayna S.; Keswani, Rajesh N.; Cote, Gregory A.; Ammar, Tarek; Al-Lehibi, Abed H.; Komandur, Srinadh; Mullady, Daniel; Jonnalagadda, Sreenivasa S. (2016-09-27)
    Subepithelial lesions (SEL) found at EGD are a common indication for EUS. Many lesions are small and asymptomatic, but national guidelines encourage EUS to characterize and sample these lesions. We established a prospective ...
  • 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 ...
  • Routine PET does not alter nodal staging in patients undergoing EUS-FNA for esophageal cancer 
    Azar, Riad R.; Keswani, Rajesh N.; Early, Dayna; Edmundowicz, Steven A.; Govindan, Ramaswamy (2016-09-28)
    Background: Accurate staging of patients with esophageal cancer is critical for optimal management. Patients with metastatic involvement of regional lymph nodes may not benefit from primary surgical resection. The aim of ...
  • Routine positron emission tomography does not alter nodal staging in patients undergoing EUS-guided FNA for esophageal cancer 
    Azar, Riad; Keswani, Rajesh N.; Early, Dayna S.; Edmundowicz, Steven A.; Meyers, Bryan F.; Sharma, Akash (2016-06-21)
    Background: Although EUS-guided FNA (EUS-FNA) and 18F-fluorodeoxyglucose–positron emission tomography (FDG-PET) are both used in the staging of esophageal cancer, the utility of routinely performing both tests is ...
  • Spyglass direct visualization system cholangiopancreatoscopy 
    Azar, Riad R.; Jonnalagadda, Sreenivasa S.; Keswani, Rajesh N.; Sadeddin, Esmat Z.; Edmundowicz, Steven A. (2016-09-08)
    Background: Direct visualization of the biliary and pancreatic ducts may be beneficial in targeting tissue biopsies and electrohydraulic lithotripsy (EHL). However, cholangiopancreatoscopy has infrequently been performed ...
  • Stenting for malignant colonic obstruction 
    Azar, Riad; Keswani, Rajesh N.; Edmundowicz, Steven A.; Zhang, Qin; Ammar, Tarek; Banerjee, Bhaskar (2016-06-20)
    Background: Self-expandable metal stent placement for palliation of malignant colonic obstruction for colorectal cancer (CRC) is safe and efficacious. In contrast, outcomes of stent placement for extracolonic malignancy ...
  • Use of a pancreatic duct stent or guidewire facilitates bile duct access with low rates of precut sphincterotomy 
    Azar, Riad R.; Coté, Gregory A.; Mullady, Daniel K.; Jonnalagadda, Sreenivasa S.; Keswani, Rajesh N.; Wani, Sachin B.; Hovis, Christine E.; Ammar, Tarek (2016-09-19)
    Background and Study Aims Among cases of difficult biliary cannulation, alternatives include use of a pancreatic duct stent (PDS) or guidewire (PDW) to facilitate access. We compared the effectiveness of a PDS versus a ...
  • Wire-assisted access sphincterotomy of the minor papilla 
    Azar, Riad; Maple, John T.; Keswani, Rajesh N.; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa (2016-06-21)
    Background Recommended techniques for minor papilla sphincterotomy include performing a standard pull-type sphincterotomy (PTS) or using a needle-knife over a stent. A wire-assisted access sphincterotomy (WAAS) technique ...
