What is Gastroenterology?

Gastroenterology is the branch of medicine focused on the digestive system and its disorders. The types of diseases that affect the gastrointestinal tract include organs from the mouth to the anus, along the alimentary canal.

What is a Gastroenterologist?

A gastroenterologist specializes in the diagnosis and treatment of conditions involving the digestive/gastrointestinal (GI) tract. They typically have completed about eight years of pre-medical and medical education, a year-long internship, three years of an internal medical residency and two to three years in a gastroenterology fellowship. These physicians are experts on how food moves through the digestive system and is chemically broken down.

What do Gastroenterologists do?

A gastroenterologist specializes in the evaluation, diagnosis, management and treatment of the following conditions:

  • Abdominal pain and discomfort
  • Bleeding in the digestive tract
  • Cancer (e.g., colorectal cancer, stomach [gastric] cancer, pancreatic cancer, liver cancer)
  • Constipation and diarrhea
  • Difficulty swallowing
  • Diverticular disease and other diseases of the colon (e.g., polyps, irritable bowel syndrome [IBS], colitis, Crohn’s disease)
  • Gallbladder disease
  • Heartburn and gastroesophageal reflux disease (GERD)
  • Hemorrhoids
  • Hiatal hernias
  • Inflammation in the digestive tract (e.g., gastritis)
  • Liver disease (e.g., hepatitis, jaundice)
  • Malabsorption disorders (e.g., celiac disease, lactose intolerance)
  • Stomach upset, nausea, vomiting
  • Ulcers
  • Unexplained weight loss

Capsule Endoscopy lets your doctor examine the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum and ileum).  Your doctor will use a pill sized video capsule called an endoscope, which has its own lens and light source and will review the images on a video monitor. You might hear your doctor or other medical staff refer to capsule endoscopy as a small bowel endoscopy, capsule enteroscopy, wireless endoscopy or pill cam.

REGARDING MEDICATIONS: In general, all medications should be continued in routine dosage EXCEPT medications that will affect blood clotting. If you are on any sort of blood clotting medication, your physician should approve you stopping the medicine. Please talk with your physician if you are a Diabetic or on blood thinners.

What Occurs During the Examination?

One of the nurses will prepare you for the examination by applying a sensor device to your abdomen with adhesive sleeves (similar to tape). The capsule endoscope is swallowed and passes naturally through your digestive tract while transmitting video images to a data recorder worn on your belt for approximately eight hours.

At the end of the day and procedure, you will return to the office and the data recorder is removed so that images of your small bowel can be put on a computer screen for physician review.

Possible Complications

Although complications can occur, they are rare when doctors who are specially trained and experienced in this procedure perform the test. Potential risks include complications from obstruction. This usually relates to a stricture (narrowing) of the intestine from inflammation, prior surgery, or tumor.

It’s important to recognize early signs of possible complications. If you have evidence of obstruction, such as unusual bloating, pain, and/or vomiting, call our office immediately. Also, if you develop a fever after the test, have trouble swallowing or experience increasing chest pain, call our office immediately. Be careful not to prematurely disconnect the system as this may result in a loss of the images.

After the Procedure

You will be able to drink clear liquids after two hours and eat a light meal after four hours following the capsule ingestion unless your doctor instructs you otherwise. You will have to avoid vigorous physical activity such as running or jumping during the study.

Your doctor generally can tell you the results within the week following the procedure; however, the results of some tests might take longer. Generally, your physician’s nurse will call with the results with one week of the exam.
