title: Upper gastrointestinal endoscopy: expected post-procedural findings and adverse events.
abstract: Complications related to endoscopy are commonly encountered in the emergency department (ED) due to an increased use of outpatient diagnostic and therapeutic upper gastrointestinal endoscopic procedures. A majority of these procedures are performed on an outpatient basis, and patients with post-procedural symptoms may return to the ED. Since these patients often undergo computed tomography (CT) for diagnosis of post-procedure complications, the emergency radiologist should be familiar with the spectrum of expected post-procedural findings, as well as common and rare complications. We present a pictorial review of post-endoscopy complications and review imaging protocols in different clinical scenarios.
