• W2979054828 abstract "Purpose: Capsule endoscopy (CE) allows for direct visualization of the small bowel mucosa and has been accepted as the first line investigation in patients with obscure GI bleeding (OGIB). Furthermore, it can be used to detect regional enteritis, vascular malformations, and neoplastic processes throughout the GI tract. The objective of our study was to determine the diagnostic yield of this imaging modality as applied to an academic affiliated hospital in West Virginia. Methods: We conducted a retrospective chart review of electronic medical records of 200 patients who underwent a CE study between January 1, 2007 and December 30, 2012. Our study sample included 92 males and 108 females, with a mean age of 56 years, at the time of the CE procedure. The major indications for CE study were iron deficiency anemia (IDA, 92 patients), melena and positive fecal occult blood test (68 patients), diarrhea, and inflammatory bowel disease. The patients with IDA, melena, and positive fecal occult blood test were combined to calculate the diagnostic yield for OGIB. Results: Out of the 200 studies performed, 86 capsule endoscopies were normal studies. 114 studies demonstrated significant findings that were not otherwise detected by traditional scoping modalities. Positive findings included erosions and ulcers, tumors such lymphomas, and AV malformations. In our analysis, we saw that CE identified a cause in 39 of 92 patients with IDA, a diagnostic yield of 42.4%. For patient with melena and positive fecal occult blood test, capsule endoscopy was able to attribute a source of bleeding in 30 of 68 patients, or 44.1%. Overall, when combined, the diagnostic yield for OGIB was 43.1% (Image 1). The complication rate due to capsule retention was 6.5% for our study. Conclusion: Capsule endoscopy is a useful imaging modality to detect a variety of GI pathologies. It serves an important, sometimes adjunctive, role to diagnose disorders of the stomach, small bowel, and colon. Although our diagnostic yield using CE was 43.1% for patients with OGIB, our data is consistent with the reported literature and supports the role of CE as the minimally invasive gold standard investigation for small bowel imaging.Figure" @default.
