Abstract

Ingested foreign bodies are one of the reasons why patients need to be hospitalized in the emergency room. Although most gastrointestinal foreign bodies can be eliminated from the body on their own, there are still some cases that cause complications, even death. In terms of foreign body morphology, there are 3 main groups, sharp-pointed foreign bodies, round foreign bodies and long foreign bodies, of which sharp-pointed foreign bodies are the group that often causes complications, especially perforation complications. There are many methods to diagnose this condition such as X-ray, computed tomography (CT) and endoscopy. In recent years, the popularity of CT has made this method widely used in the assessment of sharp-pointed gastrointestinal foreign bodies. Objective: In order to evaluate the effectiveness of CT in diagnosing sharp foreign bodies, we would like to conduct the study "Value of computed tomography in evaluation of sharp-pointed ingested foreign bodies". Subjects and research methods: A descriptive study of 25 patients with sharp-pointed foreign bodies in the gastrointestinal tract who underwent CT scan at the Radiology Department of Hanoi Medical University Hospital for 2 years, and underwent endoscopic and surgical or percutaneous intervention to remove of foreign bodies.

Results: the most common site for foreign bodies was the jejunum, followed by the stomach, colon, and esophagus. Transmural foreign body accounted for the highest rate (14/25 cases). The most common complication of sharp-pointed foreign body on CT is perforation with 16/25 cases, followed by abscess with 04/25 cases. CT scan has high sensitivity and specificity in evaluating complications of sharp-pointed foreign bodies.

Conclusion: CT has an important role in detecting and diagnosing sharp-pointed gastrointestinal foreign bodies as well as evaluating associated complications.
