Background Foreign bodies(FBs)lodged in the intestine or causing intestinal complications are uncommon in clinical practice but may pose diagnostic difficulties and prove life-threatening.This study aimed to evaluate the risk factors for severe complications and surgery to aid clinicians in the diagnosis and management of intestinal FBs.Methods We performed a retrospective analysis of patients in whom FBs were lodged in the intestine or caused complications from 2010 to 2020 in the First Affiliated Hospital of Wenzhou Medical University(Zhejiang,China).The characteristics of the patients and FBs,symptoms,imaging findings,diagnostics,treatment strategies,and clinical outcomes were analysed.Furthermore,the risk factors for complications and surgery were investigated.Results In total,180 patients were included in our study.Most patients(76.1%)were unable to provide a history of ingestion.Bezoars were the most common FBs(35.6%).The FBs were mainly located in the duodenum(32.8%)and the ileum(27.8%).Surgical removal of FBs was successful in 89(49.4%)patients and endoscopic removal in 54(30.0%)patients.Eleven with perforations were treated conservatively.FBs located in the jejunum or ileum were more likely to cause severe complications than those located in the duodenum.FBs located in the jejunum,ileum,or sigmoid colon were more likely to undergo surgery,and severe complications were an independent risk factor for surgery.Conclusion Intestinal FBs,often localized in angulation,are likely to be misdiagnosed because most patients do not provide a history of FB ingestion.Surgery and endoscopic therapy are the most commonly used treatment modalities.Surgery is not mandatory in clinically stable patients with small and contained perforations.FBs located in the jejunum or ileum are risk factors for both complications and surgery.
