A Case of Massive Lower Gastrointestinal Bleed from a Cystic Artery Pseudoaneurysm Bleeding through a Cholecystocolic Fistula.

BACKGROUND Acute lower gastrointestinal bleeding (GIB) is often associated with favorable outcomes. It is readily diagnosed and managed with colonoscopy, or may resolve spontaneously. Rarely, extra-colonic sources of bleeding may masquerade as lower GIB, posing a diagnostic challenge and potentially lead to harm if there are therapeutic delays.

Improving High-resolution Impedance Manometry Using Novel Viscous and Super-viscous Substrates in the Supine and Upright Positions: A Pilot Study.

Background/aims: Swallows with viscous or solid boluses in different body positions alter esophageal manometry patterns. Limitations of previous studies include lack of standardized viscous substrates and the need for chewing prior to swallowing solid boluses. We hypothesize that high-resolution impedance manometry (HRiM) using standardized viscous and super-viscous swallows in supine and upright positions improves sensitivity for detecting esophageal motility abnormalities when compared with traditional saline swallows.

A Novel Sleep Positioning Device Reduces Gastroesophageal Reflux: A Randomized Controlled Trial.

Goal: We hypothesized that sleeping left-side down with the head/torso elevated reduces recumbent gastroesophageal reflux (GER).

Background: Previous studies show that sleeping with head of bed elevated or on wedge reduces GER and lying left-side down reduces GER versus right-side down and supine. No prior studies have evaluated the potential compounding effects of lying in an inclined position combined with lateral positioning on GER.
