[Endoscopic management of ingested foreign bodies in the upper gastrointestinal tract in childhood: a retrospective study of 1 334 cases].

To explore the clinical features and complications of foreign bodies in the upper gastrointestinal tract in children and to investigate the effectiveness of endoscopic management. Data of patients with foreign bodies in upper gastrointestinal tract were collected retrospectively at Endoscopy Center, the Children's Hospital, Zhejiang University School of Medicine, from January 2011 to December 2016. Clinical characteristics, the types of foreign bodies, the location and duration of foreign body impaction were summarized. The risk factors of complications and endoscopic removal failure were analyzed by using Logistic regression analysis. A total of 1 334 patients (825 males and 509 females) were enrolled. The median age was 2.5 years, with a range from 0.25 to 15 years and peak age 1-3 years. Twenty patients had esophageal diseases. The most common foreign body ingested was coin (964, 72.3%). Foreign bodies were most commonly located in the esophagus (1 002, 75.1%), especially in the upper esophagus (857, 85.5%). The duration of foreign body impaction ranged from 3 hours to 5 years. Among 1 334 patients, 252 patients (18.9%) developed complications, including ulcers (101, 40.0%) and perforations(13, 5.2%). The success rate of endoscopic removal was 96.6% (1 288). By Logistic regression analysis, sharp foreign body ingestion (=6.893, 95% 4.421-10.746) , esophageal impaction (=5.253, 95%3.352-8.233) and foreign body impaction longer than 24 hours (=4.336, 95%3.091-6.082) were risk factors of complications. Sharp foreign body ingestion was the risk factor of endoscopic failure (5.372, 95%2.773-10.406) . Coin is the most common foreign body in upper gastrointestinal tract. Sharp foreign bodies impacted in the esophagus over 24 hours increase the risk of complications. Endoscopic removal of foreign bodies from the upper gastrointestinal tract in children has a high success rate. Sharp foreign body ingestion increases the risk of failure in endoscopic removing.
