Core Tip
Core tip: We investigated the status of foreign bodies in the upper gastrointestinal tract and assessed risk factors for complications associated with the endoscopic removal of ingested foreign objects. We concluded that a longer duration of impaction, above 12 h, and sharp-pointed objects were related to the occurrence of endoscopic complications and failure. A strength of this study is that we evaluated risk factors for complications according to particular impaction time, in contrast to published studies that reported simply “long” impaction duration as a risk factor or that impaction time was not associated with the risk of complications.
