Gastroenterology at St. Joseph Health Medical Group

Our experts provide comprehensive diagnostic and therapeutic services for gastrointestinal and biliary disorders ranging from inflammatory bowel disease to GERD. In addition to expert physicians, our gastroenterology program features state-of-the-art equipment and innovative treatments. The Digestive Care Center in Santa Rosa aims to provide comprehensive gastrointestinal care to surrounding communities. We are pleased to offer Endoscopic Ultrasound (EUS) to augment our biliary and oncologic services. EUS allows ultrasound imaging and biopsy of the gastrointestinal mucosal layers and can often enhance and improve management and treatment options.

Procedures Performed

Capsule Endoscopy

Capsule endoscopy enables the physician to look inside the esophagus, stomach, and small intestine, but is primarily designed for the small intestine or esophagus. The procedure can be used to discover a source of bleeding suspected to be in the small bowel, to diagnose Crohn's disease, or to screen for Barrett's change of the esophagus. At the beginning of the procedure, you will swallow a small capsule about the size of a glucosamine tablet or a large vitamin pill, which will wirelessly transmit images to a storage device that you will wear.
