Answer
Pinworm (Enterobius Vermicularis)
Pinworm, Enterobius vermicularis, also called oxyuris vermicularis, is an intestinal roundworm endemic in both temperate and tropical regions and common especially in schoolage children. It is especially common in group living conditions. The pinworm can be found in the caecum and colon. Anal pruritus is the most common symtom, but the infection can be associated with abdominal pain. The adult female pinworm is about 10 millimeters long, the male pinworm is much smaller. The female worm lays eggs in the perianal region, and the worm is transmitted from person to person via the infected persons hands, or by bedclothes. Enterobius vermicularis can be treated with several antihelminthic drugs, e.g. pyrantel pamoate, pyrvinium pamoate or mebendazole. |

I had a patient reffered for an atypical abdominal symptomatology and I found a huge ascaris lumbricoides in the cecum. First thought was an artefact produced by a vegetable fiber, but it start ... moving. I believe the situation is generated by the use of isoosmolar colonic lavage which brings those worms in the colon. Best wishespinworms--thank you :)
