ANEZ, M et al. Enteroscopia doble balón y videocápsula endoscópica en el diagnóstico de patologías del intestino delgado: Hospital Universitario de Maracaibo. 2007-2010. Gen [online]. 2011, vol.65, n.2, pp.117-122. ISSN 0016-3503.

Introduction: Double Balloon Enteroscopy (DBE) and Endoscopic Viocapsule (EVC) were introduced in the University Hospital of Maracaibo since 2007 and 2008, respectively. Their performance in diagnosing small bowel diseases were analyzed and compared. Patients and Methods: Cases undergoing upper DBE (UDBE), lower DBE (LDBE) and/or CE, were retrospectively reviewed since the introduction of these techniques, until January 2010. Results: In 94 cases (♂: 55; ♀:39; Ages: 10 to 89), 155 diagnostic procedures were performed: 52 UDBE, 8 LDBE, 16 EVC and 79 combined procedures. Predominating indications: obscure gastrointestinal bleeding, upper and/or lower gastrointestinal bleeding, anemia, chronic diarrhea, and suspicion of an intestinal tumor. Full visualization of small bowel: 86.7% (UDBE), 57.7% (DBUE) and 100% (EVC). Biopsies, therapies and/or India ink tattooing: 58.2% (UDBE) and 23.1% (DBLE). Predominant endoscopic diagnoses: vascular malformations, parasitic enteropathies, malign tumor, ulcerative enteropathies and erosive enteropathies. Agreement indication/diagnosis: 74.3% (UDBE), 57.7% (LDBE) and 70% (EVC). Conclusions: DBE and EVC constitute efficient methods with particular advantages for diagnosing small bowel pathologies: DBE allows additional procedures; EVC provides a greater chance of full visualization of small intestine. In specific cases, combination of these tests could improve their diagnostic and therapeutic efficiency.
