Video capsule endoscopy in patients with iron deficiency anaemia: experience at a regional Australian service

Abstract

Abstract Objective The objective of this study was to identify the diagnostic performance of video capsule endoscopy (VCE) among patients presenting with iron deficiency anaemia (IDA) and negative bidirectional endoscopy to a gasteroendoscopy practice in regional Australia. The secondary objectives were to identify the distribution of findings and factors predictive of positive findings in a regional setting. Results In total 123 procedures were included in the study. Mean age of the patients was 67.9 years. Females made up 60.2% (n = 74) of the study population. Mean haemoglobin and ferritin levels were 93.3 g/L and 11.9 ug/L, respectively. Positive findings were present in 67 procedures (54.5%) with the most frequent finding being small bowel angiodysplasia (53.7%, n = 36/67), followed by ulceration/significant erosion (26.8%, n = 18/67), fresh blood (20.8%, n = 14/67) and tumour/polyp (16.4%, n = 11/67). Haemoglobin level was the only variable associated with positive findings (p = 0.005) in the study population. Of the procedures reporting positive findings outside the small bowel, the majority (80%) were within reach of conventional upper endoscopy and may have implications for future practice, particularly when allocating health resources in a rural setting.
