Abstract
BACKGROUND: Soft tissue foreign bodies (FBs) are very commonly observed in paediatric emergency departments. Not all FBs can be removed effectively, even via open surgery and image intensifier guidance. In the current study, we evaluated the efficiency of FB removal with the assistance of ultrasound (US) and methylene blue (MB) staining. METHODS: We enrolled 80 patients at our clinical center between May 2016 and December 2020. Eleven patients were operated upon with the assistance of US guidance and MB and were defined as group A; the other 69 patients were defined as group B. For the patients in group A, US was first used to locate the FB; MB was then injected next to the FB. Open surgery was subsequently performed. For group B, the FBs were removed by conventional methods. The surgical outcomes were evaluated according to surgical duration, incision infection rates, radiograph exposure times, and FB residue rates. RESULTS: The average surgery time for group A was 0.35 ± 0.10 hours; the corresponding time was 0.49 ± 0.50 hours in group B and there was a significant difference between the groups (p = 0.032). The radiograph exposure times were 1.33 ± 0.34 in group A and 4.65 ± 1.81 times in group B (p = 0.021). CONCLUSIONS: This study demonstrates that assistance of US and MB staining is a more efficient approach compared with traditional methods for FB removal, and this surgical method can be used effectively for FB removal in children.
