Study to determine typical transit time for a swallowed Lego figurine head

Aim

Children frequently ingest coins (generally with minimal reported side effects); however, the ingestion of other items has been subject to less academic study. Parental concern regarding ingestion applies across a range of materials. In this study, we aimed to determine typical transit times for another commonly swallowed object: a Lego figurine head.

Methods

Six paediatric health‐care professionals were recruited to swallow a Lego head. Previous gastrointestinal surgery, inability to ingest foreign objects and aversion to searching through faecal matter were all exclusion criteria. Pre‐ingestion bowel habit was standardised by the Stool Hardness and Transit (SHAT) score. Participants ingested a Lego head, and the time taken for the object to be found in the participants stool was recorded. The primary outcome was the Found and Retrieved Time (FART) score.

Results

The FART score averaged 1.71 days. There was some evidence that females may be more accomplished at searching through their stools than males, but this could not be statistically validated.

Conclusions

A toy object quickly passes through adult subjects with no complications. This will reassure parents, and the authors advocate that no parent should be expected to search through their child's faeces to prove object retrieval.
