Oral IBGard™ Before Colonoscopy: A Single-Center Double-Blinded, Randomized, Placebo-Controlled Trial.

Background: Peppermint oil is well known to inhibit smooth muscle contractions, and its topical administration during colonoscopy is reported to reduce colonic spasms.

Aims: We aimed to assess whether oral administration of IBGard™, a sustained-release peppermint oil formulation, before colonoscopy reduces spasms and improves adenoma detection rate (ADR).  METHODS: We performed a single-center randomized, double-blinded, placebo-controlled trial.

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.

Hemobilia: Etiology, diagnosis, and treatment.

Hemobilia refers to bleeding from and/or into the biliary tract and is an uncommon but important cause of gastrointestinal hemorrhage. Reports of hemobilia date back to the 1600s, but due to its relative rarity and challenges in diagnosis, only in recent decades has hemobilia been more critically studied. The majority of cases of hemobilia are iatrogenic and caused by invasive procedures involving the liver, pancreas, bile ducts and/or the hepatopancreatobiliary vasculature, with trauma and malignancy representing the two other leading causes.

Hemobilia: Historical overview, clinical update, and current practices.

Hemobilia refers to macroscopic blood in the lumen of the biliary tree. It represents an uncommon, but important, cause of gastrointestinal bleeding and can have potentially lethal sequelae if not promptly recognized and treated. The earliest known reports of hemobilia date to the 17th century, but due to the relative rarity and challenges in diagnosis of hemobilia, it has historically not been well-studied.

Difficult biliary cannulation: Historical perspective, practical updates, and guide for the endoscopist.

Despite improvements in endoscopic technologies and accessories, development of advanced endoscopy fellowship programs, and advances in ancillary imaging techniques, biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) can still be unsuccessful in up to 20% of patients, even in referral centers. Once cannulation has been deemed to be difficult, the risk of post-ERCP pancreatitis and technical failure inherently increases. A number of factors, including endoscopist experience and patient anatomy, have been associated with difficult biliary cannulation, but predicting a case of difficult cannulation a priori is often not possible.
