Abstract

Endoscopic removal of foreign bodies (FB) impacted in the alimentary tract represents a critical and technically challenging emergency scenario. This retrospective study aimed to evaluate the clinical outcomes of endoscopic intervention for FB removal and to identify independent risk factors associated with procedural failure.
A single-center retrospective analysis was conducted on consecutive patients with a confirmed diagnosis of FB impaction in the upper or lower gastrointestinal (GI) tract between January 2010 and December 2024. Baseline demographics, clinical presentations, and endoscopic characteristics were reviewed. The success rate of endoscopic retrieval, along with procedure-related complication rates, were investigated. Independent predictors of endoscopic failure were identified using multivariable logistic regression analysis.
A total of 1,162 cases were analyzed (51.3% male; 55.6% aged ≥60 years). The vast majority of FBs were located in the upper GI tract (97.3%) and resulted from unwitnessed or accidental ingestions (89.7%). Endoscopic removal was successful in 1140 cases (98.1%), with 84.7% completed within 24 h of symptom onset. The incidence of moderate-to-severe complications was 0.6%, with no death related to FB impaction or endoscopic intervention. Independent risk factors for endoscopic failure included sharp pointed FB (p = 0.014), delayed intervention exceeding 24 h (p = 0.035) and multiple endoscopic attempts (p < 0.001).
Endoscopic management of GI tract FB impaction is highly effective and carries a favorable safety profile. Early recognition of factors predictive of endoscopic failure may enhance the success rate of FB removal in emergency situations.
