Background: Stereotactic radiation by using fiducial markers permits higher doses of radiation while reducing the exposure of uninvolved, adjacent structures. EUS has been used to deploy fiducials, although a 19-gauge ...
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, ...

Background & Aims Propofol is an effective sedative in advanced endoscopy. However, the incidence of sedation-related complications is unclear. We sought to define the frequency of sedation-related adverse events, ...
Obesity as a risk factor for sedation-related complications during propofol-mediated sedation for advanced endoscopic procedures

Azar, Riad; Wani, Sachin; Hovis, Christine E.; Hovis, Robert M.; Cote, Gregory A.; Hall, Matthew; Waldbaum, Lawrence (2016-09-09)

Background There are limited data on the safety of anesthesia-assisted endoscopy by using propofol-mediated sedation in obese individuals undergoing advanced endoscopic procedures (AEPs). Objective To study the association ...
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 ...
Predicting Difficult Bile Duct Cannulation: Accuracy of Endoscopic Visualization of the Papilla to Predict Cannulation Difficulty

Azar, Riad R.; Cote, Gregory A.; Hovis, Christine E.; Edmundowicz, Steven A.; Jonnalagadda, Sreenivasa S.; Mullady, Daniel (2016-09-08)

Predicting difficult cannulation of the common bile duct (CBD) may impact the approach to CBD cannulation.
Predictivevalue of noninvasive imaging as a precursor to ERCP in the assessment of early complications post-orthotopic liver transplant (OLT)

Azar, Riad R.; Merrill, Joseph T.; Iskander, John M.; Seetharam, Anil B.; Hovis, Christine E.; Cote, Gregory A.; Al-Lehibi, Abed; Early, Dayna S. (2016-09-26)

Abnormal LFTs in post- OLT patients can be multi-factorial. Hepatocellular, vascular causes and biliary duct abnormalities should be considered in the differential diagnosis. Biliary complications including strictures, ...
