Abstract: Objective: To explore the clinical characteristics and treatment of foreign bodies in children′s digestive tract. Methods:
Clinical data of 112 cases of children with foreign bodies in digestive tract admitted to Shengjing Hospital of China Medical University
from January 2012 to June 2018 was retrospectively analyzed. Among the 112 cases, 83 were of foreign bodies in the esophagus, 7 were
of foreign bodies in the gastroduodenum, and 22 were of foreign bodies in intestinal tract. The 90 cases of foreign bodies in the
esophagus and gastroduodenum were treated with endoscopic removal. Among the 22 cases of foreign bodies in intestinal tract, 14
received conservative treatment and 8 underwent surgeries. Results: 85 cases of foreign body showed different manifestations
depending on the location, 27 cases were asymptomatic, and all were diagnosed based on history of mistakenly swallowed foreign bodies
and imaging. 90 cases of foreign body removal by endoscope were safely removed. 14 cases were conservatively treated for an average of
6.3 d and the foreign bodies were excreted through the anus. No open surgery was performed. 8 cases of foreign body removal through
surgeries were successfully treated, among which the foreign bodies were found in the jejunum in 3 cases, in the ileum in 4 cases, and
in the cecum in 1 case. Postoperative complications of incision and suppuration happened in 2 cases, and all children were cured and
discharged. Conclusion: Children′s clinical manifestations vary greatly after swallowing foreign bodies. Comprehensive treatment
decisions need to be made based on the size, nature, location, duration of disease. Asymptomatic foreign bodies can be closely
observed, but active intervention is required when serious complications occur.
