New Non-Surgical Hemorrhoid Treatment Now Available

Hemorrhoids can mask symptoms of colorectal cancer, the second leading cause of cancer death in the United States, and until now, surgery was frequently recommended to treat hemorrhoids. GI Associates is now providing a treatment that is clinically proven and utilizes the proprietary and patented CRH O’Regan SystemTM, which is performed in the office.   Dr. Christopher A. Young, Dr. Veronika Gagovic, Dr. Benjamin M. Schneeberger and Dr. James A. Schlais all perform this new non-surgical hemorrhoid treatment at GI Associates.

"This method is faster, more accurate and has virtually no downtime for patients," said Dr. Christopher A. Young, Board Certified Gastroenterologist at GI Associates. "I am pleased to offer a procedure that provides the patient with symptom relief and a minimum level of discomfort."
