  • 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) ...
  • Conservative Therapy vs. Percutaneous Drainage of Bilomas in Patients Treated Endoscopically for Bile Leak After Laparoscopic Cholecystectomy 
    Azar, Riad R.; Merrill, Joseph; Cote, Gregory A.; Early, Dayna S.; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa (2016-09-19)
    Background: Bile leaks are the most common complication of laparoscopic cholecystectomy (CCY), occurring in about 1% of all patients. Endoscopic therapy is effective with resolution of the leaks in 85-100% of patients with ...
  • 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 removal of the Bravo pH capsule because of severe odynophagia 
    Azar, Riad; Jonnalagadda, Sreenivasa; Prakash, Chandra; Haroian, Laura; Clouse, Ray E. (2016-06-22)
    Purpose: Bravo pH monitoring is an innovative wireless system that allows ambulatory assessment of esophageal acid exposure using a radiotelemetery capsule. The device is attached to the distal esophagus by deployment of ...
  • Endoscopic removal of the wireless pH monitoring capsule in patients with severe discomfort 
    Azar, Riad; Prakash, Chandra; Jonnalagadda, Sreenivasa; Clouse, Ray E. (2016-06-21)
    Background Few patients have significant symptoms during wireless esophageal pH monitoring, and the capsule typically sloughs spontaneously. Severe discomfort during monitoring can occur that requires endoscopic dislodgement ...
  • 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. ...
  • 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 ...
  • Pancreaticopleural fistula 
    Azar, Riad; Oh, Young S.; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa (2016-06-20)
    Pancreaticopleural fistulas are a rare complication of pancreatitis. We report two cases from our institution and review 37 cases of pancreaticopleural fistulas identified in the literature. Endoscopic retrograde ...
  • Pancreatitis following Olanzapine therapy 
    Azar, Riad; Kerr, T. A.; Jonnalagadda, Sreenivasa (2016-06-22)
    Context: Atypical antipsychotic agents (clozapine, olanzapine) have been linked to metabolic effects and acute pancreatitis. Case Report: We reviewed the inpatient and outpatient records of three patients who developed ...
  • Pancreatitis is frequent among patients with side-branch intraductal papillary mucinous neoplasia diagnosed by EUS 
    Azar, Riad; Ringold, Daniel A.; Shroff, Puneet; Sikka, Sanjay K.; Ylagan, Lourdes; Jonnalagadda, Sreenivasa (2016-06-21)
    Background Because of greater recognition and improved imaging capabilities, intraductal papillary mucinous neoplasms (IPMNs) are being diagnosed with increasing frequency. IPMNs of the main pancreatic duct cause symptoms ...
  • 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 ...
  • Successful endoscopic management of gastrojejunal anastomotic strictures after Roux-en-Y gastric bypas 
    Azar, Riad; Peifer, Kevin J.; Shiels, Aaron J.; Rivera, Ramon E.; Eagon, J. Chris; Jonnalagadda, Sreenivasa (2016-06-20)
    Background Roux-en-Y gastric bypass is the most frequently performed bariatric surgery for morbid obesity. Gastrojejunal anastomotic strictures are a relatively frequent postoperative complication. Objective To evaluate ...
  • 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 ...
  • Wire-guided pancreatic pseudocyst drainage by using a modified needle knife and therapeutic echoendoscope
