A tool for diagnosis

Capsule endoscopy is a procedure that helps diagnose many different diseases of the gastrointestinal tract that cannot be seen with other types of endoscopy. Capsule endoscopy involves swallowing a pill that contains a color video camera and a wireless radio frequency transmitter and enough battery power for an eight-hour journey through the digestive tract. Common reasons for doing capsule endoscopy include unexplained bleeding, unexplained iron deficiency, unexplained abdominal pain, search for polyps, ulcers and tumors of small intestine and inflammatory bowel disease such as Crohn’s Disease. Capsule endoscopy may be right for you if you are experiencing any of the following conditions:

  • Chronic Diarrhea and Abdominal Pain
  • Crohn’s Disease
  • Polyposis syndrome
  • Abnormal imaging of gastrointestinal tract
  • Obscure gastrointestinal blood loss been recommended for you

About the Procedure

During the procedure, everything will be done to help you be as comfortable as possible. Your blood pressure, pulse and blood oxygen level will be carefully monitored. Patients generally arrive at the office early in the morning where a sensory belt is applied to the patient’s abdomen, and a battery pack is attached to the patient’s waist. Next, a pill-sized video capsule containing a miniature video camera, light bulb, battery and transmitter is swallowed to photograph the esophagus, stomach and small intestine. As the capsule travels through the body, thousands of photographs are taken and transmitted to a small Bluetooth® receiver worn by the patient. You are not required to stay at the office during the procedure and may go on with your daily routine.

Dr. Singh, Dr. Rashbaum, Dr. Nitin Parikh, Dr. Sumana Moole, Dr. Long B. Nguyen, Tammi D’Elena, PA-C; and Vanessa T. Dang, MSN, APRN  will review the pictures and either discuss the results over the phone or at a scheduled follow-up appointment with a report of the diagnosis. It’s important to remember that capsule endoscopy can only help diagnose a problem. If treatment is required, a full endoscopic procedure may be necessary to remove and correct the problem.

Aftercare and Recovery

Two hours after the capsule has been swallowed, you can only have clear liquids. After four total hours, you may slowly reintroduce regular food and medication. After eight hours you must return to the Digestive Care Physicians’ office so that the photographs can be downloaded to a computer. The capsule will be passed in your feces within 48 hours with no further action needed.
