Patient was asymptomatic, and visualized here were numerous white worms seen throughout the colon. He will be treated with 3 day course of mebendezole*.
*Treatment could also be done with a single dose of Albendazole (400mg) or mebendazole (100mg), but treatment should be repeated in about 2 weeks to prevent reinfection as eggs can persist in the environment for up to 2 weeks. Household contacts should also be treated.
