Acute stress could expose sensory nerve endings in the esophagus to refluxed gastric contents and contribute to symptoms of GERD, a new study found. Researchers say results could lead to treatments for difficult-to-treat GERD patients.

Physicians are beginning to offer patients a less invasive procedure to diagnose cancer involving the digestive tract or lungs through endoscopic ultrasonography. The procedure, which combines ultrasound and endoscopy, can help in testing the depth of invasion of certain cancers, staging and imaging areas of the GI tract.
