Abstract The etiopathogenesis of Zenker’s diverticulum (ZD) remains uncertain. Increased hypopharyngeal pressure due to a hypertonic upper esophageal sphincter results in herniation proximal to the sphincter producing a pulsion diverticulum. Gastroesophageal reflux, which is known to induce shortening of the injured esophagus, likely plays a prominent role in ZD formation by pulling the cricopharyngeus muscle (CPM) away from the anchored inferior constrictor muscle. This creates...

The diagnosis of bile acid diarrhea should be considered amongst all patients with chronic diarrhea, even when known risk factors are absent. Abstract Background 23‐seleno‐25‐homo‐tauro‐cholic acid (SeHCAT) scanning to rule out bile acid diarrhea (BAD) in patients with chronic diarrhea has a high yield. Our previous study showed that patients with terminal ileal (TI) Crohn's disease, TI resection, or cholecystectomy were highly likely to have an abnormal scan. As a result, we encouraged clinicians...
