In the present case, capsule endoscopy contributed to the diagnosis of diphyllobothriasis infection through the direct observation of the live parasite in the small intestine. It is noteworthy that the capsule endoscopy identified numerous proglottids as well as forefront of the parasite; thus, suggesting that this examination is a practical and effective procedure for determining whether additional treatment is required to treat a Diphyllobothrium
infection. Seven reported cases and the present patient with tapeworm infection detected by capsule endoscopy5–10
are summarised in . Three subjects were infected by Diphyllobothrium spp
, while the other five were infected by Taenia
. Four subjects had histories of eating raw fish or meat. Capsule endoscopy detected a scolex or forefront of the parasite in six cases and proglottids in all eight cases. In four cases, the cause of anaemia was attributed to tapeworm infection. In the present case, capsule endoscopy was useful to confirm the remaining scolex or forefront of the parasite, which might cause a relapse of the diphyllobothrium infection and it is also a safer and more comfortable method for the patient. Based on the results of capsule endoscopy, the patient underwent additional vermifuge treatment to cure the diphyllobothriasis.
Reported cases with tapeworm infection detected by capsule endoscopy
In summary, the present study demonstrates that capsule endoscopy is a feasible option to identify tapeworm infection and also to determine whether additional vermifuge treatment is required through the detection of the proglottids as well as a scolex or forefront of the parasite. Therefore, capsule endoscopy, which is a safe and less invasive procedure for observing the small intestine, may be applied to accurately diagnose parasite infections in the intestinal tract.
- Capsule endoscopy, which is a safe and less invasive procedure for observing the small intestine, is a practical procedure to detect the proglottids as well as a scolex or forefront of the parasite.
- Capsule endoscopy is useful to determine the indication of an additional vermifuge treatment.
- Therefore, capsule endoscopy may be applied to accurately diagnose parasite infections in the intestinal tract.
