Abstract: Most foreign bodies are often discharged without obvious symptoms after swallowing, but some may be misdiagnosed and stay in the body, resulting in serious complications. Different diagnostic methods should be integrated to diagnose such patients. Once diagnosed, they should be treated as soon as possible if necessary. The authors reported a case of retention in the body for 6 years after swallowing a wooden chopstick, resulting in the insertion into the psoas muscle after duodenal perforation, complicated by abdominal abscess. During the operation, endoscopic assisted laparoscopic foreign body removal was performed, and the patient showed good prognsis, which provided references for the diagnosis and treatment of the disease.
