Description

Hamdeh et al reported a predictive model for postive capsule endoscopy in a patient with iron deficiency anemia. This can help to improve the diagnostic yield of the procedure. The authors are from multiple institutions from around the United States.


Patient selection: iron deficiency anemia

 

Procedure: video capsule endoscopy

 

Parameters:

(1) age

(2) smoking status

(3) cardiac arrhythmia

(4) hemoglobin in g/dL prior to the procedure
