Alessandro Pezzoli, MD, from the Department of Gastroenterology, Endoscopy Unit, Sant’Anna Hospital Ferrara, in Ferrara, Italy shares this video case “Capsule endoscopy diagnosis of intestinal Taenia.”
We present here the video of a patient suffering of occult anemia, infected by a Taenia species and diagnosed by capsule endoscopy. The patient, an 81-year-old Caucasian man, was admitted to our day hospital with severe anemia (hemoglobin 5.5 gr/dl). His personal medical history included ulcerative colitis diagnosed in 2011. Upper GI endoscopy and colonoscopy were performed without relevant findings. Therefore we performed CE that revealed the presence of a long white worm.
The images produced by the capsules endoscopy show clearly the in vivo presence of the helminth. Before the advent of capsule endoscopy, the presence of an intestinal parasites could be diagnosed using a fecal exam or blood test (serology and blood smear). Radiological procedures as magnetic resonance imaging and computer tomography imaging have low sensitivity for this kind of infection. Capsule endoscopy enables the direct evaluation of the small bowel and therefore can easily detect intestinal parasites.
Helminths are among the most widespread infectious agents that affect human populations. Helminths are endemic in developing countries but more rare in western countries. However, due to immigration and traveling, new cases of helminthiasis can be diagnosed more frequently in clinical practice. This case provides useful information for endoscopists and clinicians if similar patients are met in clinical practice. Furthermore, this report outlines how capsule endoscopy can assist the diagnosis of parasitic diseases.
