Objective: To study about the number of whipworms found in the colon while doing colonoscopy in our study and compare it with other studies.

Methods: A study of 72 patients who had undergone colonoscopy for a period of 5 years from November 2009 to October 2014 was carried out. In patients found to have parasitic worms during colonoscopy, number of parasitic worms in the colon were noted. Number of whipworms found in the colon during colonoscopy in our study is compared with other studies.

Results: Out of these 72 patients, parasitic worm was found in the colon in only one patient. The parasitic worm found in this patient was identified as whipworm or trichuris trichiura by its characteristic whip like shape. It has a short posterior thick part resembling the short handle of the whip and a long, thin anterior part resembling the distal long, thin part of the whip. Our patient was found to have only single whipworm in the colon while doing colonoscopy. Our study and also some other studies have shown only a single whipworm in the colon while doing colonoscopy. Howewer other studies have shown multiple whipworms in the colon while doing colonoscopy.

Conclusion: Our study and also some other studies have shown only a single whipworm in the colon while doing colonoscopy which represents mild whipworm infection. Howewer other studies have shown multiple whipworms in the colon while doing colonoscopy which represents severe whipworm infection.
