From Capsule Endoscopy to Balloon-Assisted Deep Enteroscopy: Exploring Small-Bowel Endoscopic Imaging

Area of Science:

• Gastroenterology
• Endoscopy
• Small Bowel Diseases

Background:

• Endoscopic evaluations for obscure gastrointestinal bleeding have increased over the last 15 years.
• Indications include iron deficiency anemia, suspected Crohn's disease, small-bowel tumors, celiac disease, NSAID-induced ulcers, and familial adenomatous polyposis screening.

Purpose of the Study:

• To evaluate the role and efficacy of capsule endoscopy and balloon-assisted deep enteroscopy in diagnosing and managing small bowel diseases.
• To assess the combined diagnostic yield and therapeutic benefits of these complementary endoscopic techniques.

Main Methods:

• Review of studies examining capsule endoscopy and balloon-assisted deep enteroscopy for obscure gastrointestinal bleeding.
• Analysis of diagnostic yields and therapeutic outcomes when procedures are performed alone or in combination.

Main Results:

• Balloon-assisted deep enteroscopy has a diagnostic yield of 40% to 80%.
• Performing capsule endoscopy before balloon-assisted deep enteroscopy may improve diagnostic yields for small bowel bleeds.
• Combined techniques offer better-directed therapy for small bowel diseases.

Conclusions:

• Capsule endoscopy and balloon-assisted deep enteroscopy are safe and effective for evaluating the small bowel.
• These procedures are particularly effective as complementary techniques for improved diagnosis and treatment.
• Further research is needed on their overall efficacy, cost, safety, and expanded indications.
