Aims:

To show two different nematodes attached to colonic wall allowing their characterization by endoscopic image.

Methods:

Two edited videos of attached nematodes diagnosed in our endoscopy unit (H.G.U. Gregorio Marañón, Madrid-Spain) found during two routine colonoscopies.

Results:

1st case: 39-y.o. man from Spain with distal ulcerative colitis who abandoned clinical follow-up. He presented with increased number of stools also passing blood with suspicion of mild flare. 2nd case: 32-y.o. woman from Ecuador with rectal bleeding suggesting haemorrhoidal origin. She had no other symptoms. In 1st case, colonoscopy showed a nematode attached to sigmoid colon wall with faster movements, trend to form loops with longitudinal lined structures and longer than 2 cm.

In 2nd case, colonoscopy showed a nematode attached to the cecal wall making slow movements, with a thick and 2 – 3 cm luminal segment with groß structures consisting with sexual organs (uterus and ova).

Conclusions:

When a nematode attached to colonic wall is found, Trichuris and Anisakis are possible diagnosis. Location, morphology and specific characteristics allow a diagnostic approach. Endoscopic removal of attached worm/s is recommended.
