Is double-balloon enteroscopy an accurate method to diagnose small-bowel disorders?

Area of Science:

• Gastroenterology
• Endoscopy
• Diagnostic Imaging

Background:

• Small bowel disorders present diagnostic challenges due to limited accessibility.
• Chronic gastrointestinal bleeding, diarrhea, and polyposis are common indications for small bowel investigation.

Purpose of the Study:

• To evaluate the diagnostic contribution of double-balloon enteroscopy (DBE) in patients with suspected small bowel disorders.
• To assess the safety and efficacy of DBE in identifying and managing small intestine pathologies.

Main Methods:

• A cohort of 44 patients with various indications underwent double-balloon enteroscopy.
• Indications included obscure gastrointestinal bleeding, diarrhea, polyposis, and post-surgical evaluation.

Main Results:

• DBE achieved a 75% diagnostic yield (33/44 patients), identifying sources of bleeding and other pathologies like angiodysplasias, adenocarcinoma, and Crohn's disease.
• Therapeutic interventions were successful in 63.6% of cases.
• The procedure demonstrated a high safety profile with only minor complications (9.1% sore throat).

Conclusions:

• Double-balloon enteroscopy is a safe and accurate endoscopic method for diagnosing a wide spectrum of small bowel disorders.
• DBE facilitates crucial diagnostic procedures including chromoscopy and biopsies, as well as therapeutic interventions.
