Diagnostic Yield of Spiral Enteroscopy When Performed for the Evaluation of Abnormal Capsule Endoscopy Findings

Abstract

SE seems to be moderately effective (57.1%) in terms of its ability to locate pathology within the small intestine. The type of small bowel pathology targeted by SE may affect its clinical utility. AVMs observed on CE can be seen at the time of SE in the majority of cases (60%).

The role of endoscopy in the management of suspected small-bowel bleeding

“…87 Initial series 88 reported a low diagnostic yield with spiral enteroscopy (33%), but a more recent prospective study reported a higher yield (57%-62%) and improved outcomes in terms of transfusion requirements, iron supplementation, and additional therapeutic procedures with spiral enteroscopy in patients with small-bowel disorders. 89 A modeled cost-minimization analysis of the management of small-bowel bleeding proposed BAE as the most cost-effective initial test after standard endoscopy if the goal is treatment or definitive diagnosis, as opposed to visualization alone. 90 Another model suggested that initial BAE was a cost-effective approach for patients with smallbowel bleeding who likely have angiectasias in the small bowel accessible with a single antegrade approach.…”

Advances in Small Bowel Imaging

“…In a prospective study of patients with abnormal capsule findings, the diagnostic yield of SE was 57%. [37]. In a small comparison study, there was no significant difference in the diagnostic yield with SE (33.4%) and DBE (47.1%) [38].…”

Evaluation and management of small-bowel tumors in the era of deep enteroscopy

“…However, SE failed to detect ulcerations and mass lesions in the majority of patients. 102 Additional studies are necessary to evaluate the role of SE in diagnosis of small-bowel tumors.…”
