All of the physicians at Gastrointestinal Associates provide care for patients with a broad array of gastrointestinal illnesses and complaints. All of our physicians also perform standard endoscopic procedures such as endoscopy, colonoscopy, sigmoidoscopy, and esophageal dilation. In addition, we offer a number of specialized services and programs.
Although all our physicians are highly experienced in routine endoscopic procedures, a number of more complicated procedures have been developed over the past decade. Many of our physicians have received training and have become expert in these more specialized procedures as well.
- ERCP (endoscopic retrograde cholangiopancreatography) uses a special endoscope to access the bile ducts and pancreas. This procedure offers the ability to remove stones, take biopsies, and bypass obstructions in these areas.
- EUS (endoscopic ultrasound) uses an endoscope modified with an ultrasound probe to produce highly detailed images of the GI system, pancreas, bile duct and gallbladder, as well as lymph nodes and blood vessels outside the GI tract. Biopsies can be obtained with a high degree of accuracy.
- EMR (endoscopic mucosal resection) is a technique which allows the gastroenterologist to remove large polyps from the colon which would have required surgery in previous years
- Stent placement is used to bypass obstructions in bile duct, esophagus and colon. Using a combination of endoscopic and Xray techniques, the gastroenterologist can place a small device through a narrowed area; the device expands after it is placed and provides a passageway for fluids or food.
- BARRX™ is a device which uses radio frequency waves to destroy precancerous tissue in the esophagus.
Inflammatory Bowel Disease
Our practice includes physicians who sub-specialize in the care of IBD patients. We have an on-site infusion and injection therapy center where patients can be treated with biologic agents (Remicade, Humira, Cimzia, Entyvio) in a comfortable setting, with monitoring by a physician and a specially trained nurse. Our physicians are also experienced in the management of other immunosuppressive medications such as 6-mercaptopurine and Imuran (azathioprine).
Capsule endoscopy allows our physicians to visualize the small intestine, an area of the GI tract which cannot be seen with conventional endoscopy and colonoscopy and which can cause bleeding, pain, diarrhea or other problems. Patients come to our office early in the morning to swallow a pill containing a light, camera, and transmitter. The images sent by the capsule are recorded on a receiver worn on a vest during the day of the test, then downloaded and reviewed by our doctors.
Esophageal reflux and motility
We offer specialized testing for patients with reflux, heartburn, and chest discomfort not related to heart problems. BRAVO pH monitoring is done during a conventional endoscopy. By attaching a small sensing device to the lining of the esophagus we can record acid levels for 2 days without the need for a tube or catheter. Manometry involves passing a small catheter down the esophagus and into the stomach. The catheter only needs to stay in place for 15 minutes and is used to measure the strength and coordination of muscle contractions in the esophagus.
Several of our physicians have special training and expertise in liver disease and are experienced in the rapidly evolving area of hepatitis treatment. They work closely with ancillary personnel who have been trained to provide supportive services when needed, such as instructing patients in self-injection of hepatitis medications and managing side effects of treatment. Our liver specialists have built close relationships with the liver transplant team at Thomas Jefferson University Hospital and coordinate the care of transplant patients from the initial evaluation to the post-transplant period. A transplant hepatologist from Jefferson is available in our office once or twice monthly when additional input is needed.
We offer in-office management of symptomatic internal hemorrhoids using the CRH O’Regan System, an outpatient banding system. Most patients require three brief office sessions, each done several weeks apart, to achieve complete relief of symptoms. Before banding is scheduled patients are evaluated in the office to ensure that this procedure is the appropriate treatment for that individual.
Gastrointestinal Associates was founded in 1972 by William Mahood, MD, the first board certified gastroenterologist on staff at Abington Memorial Hospital and Holy Redeemer Hospital, and the first person to introduce modern GI techniques including endoscopy and colonoscopy to Montgomery County. Over the years the practice has grown steadily and has added expertise in a wide ranging set of GI diseases and techniques. Our current staff of 17 professional health care providers is ethnically diverse and includes 5 women. In 2006 the practice opened a satellite office in Doylestown and now provides comprehensive office and procedural services to patients throughout Montgomery and Bucks Counties.
