Successful use of a novel dynamic rigidizing overtube in a patient with looping during colonoscopy.

Video 1This video is our description of use of the novel dynamic rigidizing overtube in a challenging colonoscopy case in which looping was causing significant bradycardia and inability to advance the colonoscope to the cecum. The rigidizing overtube, through sequential cycles of its flexible and rigidized state, allowed for easy movement of the colonoscope to the cecum.

Endoscopic ultrasound in chronic liver disease.

Endoscopic ultrasound (EUS) is a minimally invasive diagnostic and therapeutic modality with a number of established as well as evolving uses in patients with chronic liver disease. Compared to other diagnostic tools such as cross-sectional imaging or conventional endoscopy, EUS has been shown to increase diagnostic sensitivity and therapeutic success for many clinical scenarios and applications with a low rate of adverse events. In this review, we discuss and focus on the current and growing role of EUS in the evaluation and/or treatment of hepatobiliary masses, hepatic parenchymal disease, portal hypertension, esophageal and other varices, and indeterminate biliary strictures.

Artificial Intelligence in Gastrointestinal Endoscopy.

Artificial intelligence (AI) is rapidly integrating into modern technology and clinical practice. Although in its nascency, AI has become a hot topic of investigation for applications in clinical practice. Multiple fields of medicine have embraced the possibility of a future with AI assisting in diagnosis and pathology applications.

Intestinal Tuberculosis Masquerading as Crohn's Disease? A Case of Disseminated Tuberculosis after Anti-TNF Therapy for Suspected Crohn's Disease.

Intestinal tuberculosis (ITB) and Crohn's disease (CD) very closely resemble each other in symptomatology, imaging, appearance, and pathology. While ITB is rare in the United States, its prevalence is significantly higher in endemic areas, thus presenting a diagnostic dilemma in immigrant populations from high-risk countries. This patient was diagnosed with CD and treated with anti-TNF agents after indeterminate screening for latent tuberculosis.
