Endoscopic failure for foreign body ingestion and food bolus impaction in the upper gastrointestinal tract: an updated analysis in a European tertiary care hospital

ObjectiveHarmfulness of foreign body ingestion and food bolus impaction (FBIs) varies according to geographical area, population, habits, and diet. Therefore, studies may not draw generalizable conclusions. Furthermore, data regarding FBIs management in Europe are limited and outdated. This study aimed to analyze the endoscopic management and outcomes of FBIs in an Italian tertiary care hospital to identify risk factors for endoscopic failure. MethodsWe retrospectively reviewed patients who underwent upper gastrointestinal endoscopy for FBIs between 2007 and 2017. Baseline, clinical, FBIs, and endoscopic characteristics and outcomes were collected and reported using descriptive statistics and logistic regression analyses. ResultsOf the 381 endoscopies for FBIs, 288 (75.5%) were emergent endoscopy and 135 (35,4%) included underlying upper gastrointestinal conditions. The study population included 44 pediatric patients (11.5%), 54 prisoners (15.8%), and 283 adults (74.2%). The most common type and location of FBIs were food boluses (52.9%) and upper esophagus (36.5%), respectively. While eight patients (2.1%) developed major adverse events requiring hospital admission, the remainder (97.9%) were discharged after observation. No mortality occurred. Endoscopic success was achieved in 263 of 286 (91.9%) verified FBIs endoscopies. Endoscopic failure (8.04%) was associated with age, bone, disk battery, intentional ingestion, razor blade, prisoners, and stomach in the univariate analysis. Multivariate logistic regression revealed that intentional ingestion was associated with endoscopic failure (odds ratio: 7.31; 95% confidence interval = 2.06-25.99; P = 0.002). ConclusionEndoscopy for FBIs is safe and successful, with low hospital admission rate in children, prisoners, and adults. Intentional ingestion is a risk factor of endoscopic failure.
