Computed tomography (CT) can identify intestinal perforation from ingested foreign bodies, especially sharp, elongated ones. This is crucial in elderly patients with dental prostheses, even if they don't recall ingestion.

Area of Science:

  • Radiology
  • Gastroenterology
  • Emergency Medicine

Background:

  • Intestinal perforation due to foreign body ingestion is a rare but serious complication.
  • Diagnosis can be challenging, particularly in elderly patients or when the foreign body is not recalled.
  • Conventional radiography often fails to detect foreign bodies causing perforation.

Purpose of the Study:

  • To identify computed tomography (CT) findings suggestive of intestinal perforation caused by ingested foreign bodies.
  • To correlate CT findings with clinical presentation and outcomes.

Main Methods:

  • Retrospective review of four cases with surgically confirmed intestinal perforation by foreign bodies.
  • Comparison of CT findings with literature data.
  • Analysis of patient demographics, foreign body characteristics, and clinical presentation.

Main Results:

  • All patients presented with signs of acute abdomen; none reported foreign body ingestion.
  • Foreign bodies were elongated and sharp; three patients used dental prostheses.
  • CT revealed intestinal wall thickening and increased mesenteric fat density in all cases.
  • CT identified the foreign body perforating the bowel in three cases and detected free peritoneal gas in one.

Conclusions:

  • Elongated, sharp foreign bodies are associated with higher risk of intestinal perforation.
  • Suspect foreign body ingestion in elderly patients with dental prostheses presenting with acute abdomen.
  • CT is valuable for detecting foreign bodies, locating perforations, and guiding management, with key findings including wall thickening and mesenteric fat changes.
