Core Tip

Core tip: This study determines the results of using capsule endoscopy in obscure gastrointestinal bleeding in long-term. Our main aim was to describe the long-term clinical impact of capsule endoscopy during follow-up period. Positive capsule endoscopy results correlated with higher rebleeding rates. Independent predictors of rebleeding were detected to be usage of non-steroidal anti-inflammatory drugs, anticoagulant/antiaggregant therapy and vascular ectasia.
