Objective: To study about the gender 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 inorder to find out the presence of parasitic worms during colonoscopy in these patients. In patients found to have whipworms in the colon, gender of whipworms were noted. Gender 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 study and also some other studies have shown female whipworm in the colon while doing colonoscopy. In our patient, the tail or the posterior end of the whipworm is straight and bluntly round without any coil or corkscrew shape and hence can be identified as the female whipworm. However other studies have shown male whipworms in the colon while doing colonoscopy. In these studies whipworm was identified as male whipworm since its tail or the posterior end is highly curved and coiled like a corkscrew.
Conclusion: Thus, while doing colonoscopy we can easily distinguish between male and female whipworm by looking at the tail or posterior end of the whipworm. The tail or the posterior end of the female whipworm is straight and bluntly round without any coil or corkscrew shape. The tail or the posterior end of the male whipworm is highly curved and coiled like a corkscrew.
