Trichuriasis is soil-source parasitic disease, usually endemic in warm, humid, tropical and subtropical countries. We report a case of trichuriasis diagnosed by colonoscopy performed in a non-endemic area and review the literature on the colonoscopic diagnosis of Trichuris trichiura spanning 22 years (1989-2011) in mainland China. A total of 4382 trichuriasis cases were diagnosed by colonoscopy out of 41,337 patients who underwent colonoscopy. Most of the patients were cured by unloading the whipworms using colonoscopy pincers. We strongly suggest colonoscopy as a useful diagnostic and treatment tool, especially when the patient is lightly infected or is infected by only a few male worms with no eggs in the stool. The geographical distribution, parasite burden, and the parasitizing locations of T. trichiura in the intestine of the human body were analyzed, and the clinical signs and symptoms, as well as the utility of colonoscopy in the diagnosis and treatment of trichuriasis are discussed.
