Advanced GI Procedures

Our center for advanced gastrointestinal procedures was built exclusively for people with complex conditions.

We are home to Connecticut’s most experienced gastroenterologists, performing over 15,000 minimally invasive procedures every year. Physicians from around the world come here to learn the procedures because we have a reputation for diagnosing complicated problems and treating them with the most advanced techniques.

20180306-CT-GI-Advanced-Procedure-Team-02.jpgAt many hospitals, surgery is the only option for complicated gastrointestinal conditions. At Hartford Hospital, we have the expertise and technology others don’t: using cutting-edge, minimally invasive techniques to treat complex digestive conditions. We deliver the most advanced care available and help you avoid surgery altogether.


Advanced GI Procedures

For decades, physicians have used a flexible tube with a camera, called a scope, to enter natural openings in the body and look closely at hard-to-reach parts of the GI tract. Our expert gastroenterologists take it a step further, using this technique to treat complex digestive conditions and early stage cancer as well.

With this approach, we can offer the benefits of an extremely safe, minimally invasive technique – similar to the method used millions of times each year for routine screenings like colonoscopies – and eliminate the need for surgery. The result? Little to no pain, zero incisions, fewer risks and a shorter recovery time.
These procedures are complex, so doing them successfully and safely is extremely important. We are an international center of excellence because we pioneered many of these advanced endoscopic GI procedures right here at Hartford Hospital. Our extensive experience means we are successful in treating more than 98 percent of the patients who come to us for care.

Some of the conditions we can treat with these advanced procedures include Achalasia, Barrett’s Esophagus, Cysts, Gallstones, Gastrointestinal Cancer, Gastroparesis, Pancreatitis, Strictures, Zenker’s Diverticulu.
