An Ex-vivo Model for Electrolyte Transport Along the Small Intestine

Undifferentiated or crypt-like, and differentiated or villus-like, human intestinal enteroids represent distinct points along the crypt–villus axis and can be used to characterize electrolyte transport processes along the small intestine, researchers report in the March issue of Gastroenterology. Studies of their duodenal enteroid model showed that electrogenic Na+/HCO3– cotransporter 1 in the

What Changes Occur in the Intestine After Gastric Bypass vs Vertical Sleeve Gastrectomy ?

The intestine adapts differently to Roux-en-Y gastric bypass (RYGB) than to vertical sleeve gastrectomy (VSG), researchers show in the February issue of Gastroenterology. RYGB increases intestinal glucose disposal whereas VSG delays glucose absorption, but each reduces glycemia. Bariatric surgeries such as RYGB and VSG are the most effective ways to resolve

What is the Best Way to Remove a Bag of Methamphetamine From the Esophagus?

Researchers describe using endoscopy to remove an upper gastrointestinal obstruction caused by deliberate ingestion of illicit drug packets in the July issue of Clinical Gastroenterology and Hepatology. Timothy Cowan et al report the case of a 30 year old man in police custody after ingesting a plastic bag containing methamphetamine. The patient
