Liquid concrete as a gastrointestinal tract foreign body.

Gastrointestinal foreign bodies present a common clinical challenge. We present an unusual case of a 58-year-old construction worker who ingested liquid concrete that risked solidifying in his stomach. Gastroscopy revealed only partial solidification and pyloric obstruction, which were successfully resolved through endoscopic fragmentation and mechanical removal. To protect the gastric mucosa during elimination, liquid paraffin and a cellulose-based formula were administered. Complete gastrointestinal evacuation was achieved within 3 days, with no complications observed. This case emphasises the urgency of the early removal of concrete.
