Foreign Body Penetration through Jejunal Loops Causing Renal Artery Thrombosis and Renal Infarct.

Foreign body ingestion is common, although perforation after ingestion is rare. We report a case of an ingested sharp wooden stick that perforated the proximal jejunum toward the renal vasculature, causing segmental renal artery thrombosis and renal infarct. The patient presented with severe abdominal pain and vomiting. A computed tomography scan revealed a linear opacity corresponding to the foreign body. The wooden stick was removed endoscopically through deep-push enteroscopy with a rat-tooth forceps. We report this unique case of perforation by a foreign body through the proximal jejunum to the left kidney, which was managed endoscopically.
