Small Bowel Endoscopy: What to Expect and Why It Is Done

Small bowel endoscopy, also known as enteroscopy, is a procedure that uses a long, flexible tube with a tiny camera to look inside your small intestine. It allows doctors to see areas of the digestive tract that cannot be reached with a standard upper endoscopy or colonoscopy, helping them examine the lining closely and detect problems.

The Small Bowel Endoscopy Adverse Events test is a blood test that helps healthcare providers detect and monitor complications that may occur after a small bowel endoscopy (also called enteroscopy). This procedure allows doctors to examine the lining of the small intestine using a flexible scope with a camera. While generally safe, like any medical procedure, complications can occasionally occur.

This test is performed to find the cause of unexplained symptoms such as bleeding in the digestive tract, iron deficiency anemia, chronic abdominal pain, or abnormal findings on imaging studies. It also lets your doctor take tissue samples, remove growths, or treat bleeding areas inside the small intestine during the same procedure.

This test is performed after a small bowel endoscopy to: (1) Detect early signs of complications such as bleeding, infection, or perforation (a tear in the intestinal wall), (2) Monitor patients who are at higher risk for adverse events, (3) Guide treatment decisions if complications are suspected, and (4) Ensure patient safety during the recovery period.

During the test, you will usually receive sedation through an intravenous line to keep you comfortable. The doctor gently passes the endoscope through your mouth and advances it into your small intestine while viewing images on a monitor. The procedure typically takes 30 to 60 minutes, and your vital signs are watched closely throughout and until the sedation wears off.

A healthcare professional will draw a blood sample from a vein in your arm. The blood sample is then sent to a laboratory where it is analyzed for various markers that may indicate complications, such as signs of infection (elevated white blood cell count), bleeding (changes in hemoglobin), or inflammation.

Common adverse events after small bowel endoscopy include a mild sore throat, bloating, gas, cramping, and nausea, which usually go away within a day. Less commonly, bleeding or a tear in the intestinal wall can occur. Contact your doctor right away if you develop severe abdominal pain, fever, vomiting blood, or black, tarry stools.

While small bowel endoscopy is generally safe, potential complications may include: bleeding (especially if a biopsy or polyp removal was performed), perforation (a small tear in the intestinal wall), infection, sedation-related complications, and rare allergic reactions to medications used during the procedure. Most patients experience no significant complications.
