Double balloon endoscopy is one of the two versions of balloon endoscopy used to evaluate the condition of the large and small intestines. Both procedures use a long fiber optic tube fitted with a camera and a light on its tip. This is called an endoscope and is capable of filling the intestines with air as well as rinsing it with water. Doing this reduces discomfort and bloating caused by the procedure. The endoscope is also covered with an over tube that covers its entire length. There is a balloon fitted over this over tube that can be inflated and deflated as required. Inflating this balloon allows the endoscope to travel deep into the intestines and analyze the interiors thoroughly. In a double balloon endoscopy there is a second balloon fitted onto the tip where the camera and light are placed. This offers a more detailed view of the internal intestinal tract as well as easier maneuvering of the endoscope. Generally a double balloon endoscopy is performed when there is possibility of a disease in the small intestine or any abnormality has been recorded using a wireless capsule endoscopy.
Double Balloon Endoscopy Procedure and Preparation
A double balloon endoscopy is generally conducted under sedation and may take up to two to three hours to complete. Depending on what part of the intestine needs to be analyzed, the endoscope may be passed through the mouth or the rectum. The double balloon endoscopy procedure also involves using x-rays to check the position of the endoscope. The procedure allows for tissue biopsies and any findings to be recorded on the camera for further study and evaluation. Double balloon endoscopy preparation requires the patient to be on a completely empty stomach. No food or drink can be consumed for at least six hours before the procedure. In case the patient is allergic to any medication or has any health issues, the doctor should be informed beforehand. The double balloon endoscopy can cause mild discomfort. Patients may report a sore throat a few days after the test when the procedure is carried out through the mouth.
