Abstract: Objective To summarize the clinical features,treatment Methods and effect of endoscopic therapy of foreign bodies in children′s digestive tract,so as to provide reference for clinical diagnosis and treatment. Methods A total of 103 children with foreign bodies in digestive tract were enrolled in this study,who were diagnosed and treated in Pediatrics Department of Tangdu Hospital of the Fourth Military Medical University from December 2016 to May 2018.And the general data,foreign body types,clinical manifestations,complications,foreign body retention sites,intervention and treatment were retrospectively analyzed. Results The prevalence of foreign bodies in digestive tract in boys(75.73%) were much higher than that in girls(24.27%),and it was higher in rural areas (59.22%) than in urban areas (20.78%).Also,foreign bodies in digestive tract most occurred in toddlers (69.90%) without the supervision of parents (65.05%).Coins were the most common (50.49%) type of foreign bodies in digestive tract,esophagus was the most common (43.69%) retention site and stomach fundus was the next (36.89%).Among 103 children,83 cases were removed by electronic gastroscope,19 cases were discharged spontaneously after observation in hospital,and 1 case was removed by surgery.88 cases had esophageal or gastric mucosal lesions,3 cases were complicated with esophageal perforation and esophagotracheal fistula,and were cured by gastroscopy and bronchoscopy after treatment with acid suppression and protective film,and 1 case complicated with intestinal obstruction was cured by general surgery. Conclusions Foreign bodies in digestive tract of children are diverse and could cause gastric mucosal damage.The key point to prevent foreign bodies in digestive tract is to improve parental supervision.Furthermore,electronic gastroscopy is simple,safe and has a high success rate,which could be taken as the first choice.
