Double-balloon enteroscopy

From WikiMD's Wellnesspedia

Double-balloon enteroscopy (DBE), also known as double-balloon endoscopy, is a form of endoscopy where a specialized endoscope equipped with two balloons is used to examine the entirety of the small intestine. This technique was developed to overcome the limitations of traditional endoscopic methods, which could not reach deep into the small intestine due to its length and complex looping structure.

Overview[edit | edit source]

Double-balloon enteroscopy involves the use of a flexible endoscope that has two balloons: one at the tip of the endoscope and another on a soft overtube. The procedure can be performed either anterogradely (through the mouth) or retrogradely (through the anus), depending on the portion of the small intestine that needs to be examined or treated. The balloons are alternately inflated and deflated, allowing the endoscope to pleat the small intestine onto the overtube and advance through it without forming loops. This method provides a way to visually inspect the entire small intestine and perform therapeutic interventions such as biopsy, polypectomy, and treatment of bleeding lesions.

Indications[edit | edit source]

Double-balloon enteroscopy is indicated for a variety of conditions affecting the small intestine, including but not limited to:

Procedure[edit | edit source]

The DBE procedure is performed under sedation or general anesthesia to ensure patient comfort. Preparation for the procedure may involve fasting and, for the retrograde approach, bowel cleansing similar to that required for a colonoscopy. The endoscope is carefully advanced through the gastrointestinal tract, with the balloons being inflated and deflated to anchor the scope and allow for advancement or retraction as necessary. The procedure can take several hours, depending on the extent of examination and any therapeutic actions taken.

Advantages[edit | edit source]

The main advantage of double-balloon enteroscopy is its ability to provide access to the entire small intestine, an area that was previously difficult to reach with conventional endoscopy techniques. This allows for direct visualization of the mucosa, targeted biopsies, and the performance of therapeutic interventions without the need for more invasive surgical procedures.

Risks and Complications[edit | edit source]

While double-balloon enteroscopy is generally safe, it carries risks similar to those of other endoscopic procedures, including:

  • Perforation of the intestine
  • Bleeding
  • Pancreatitis
  • Infection
  • Adverse reactions to sedation

Conclusion[edit | edit source]

Double-balloon enteroscopy represents a significant advancement in the field of gastroenterology, offering a minimally invasive option for diagnosing and treating conditions of the small intestine. Its ability to provide comprehensive access to the small intestine has made it an invaluable tool in the diagnosis and management of complex gastrointestinal diseases.
