Ascariasis is the most common helminthic infestation in India. It affects mainly children of low socioeconomic status whose standards of public health and personal hygiene are at the lowest. Ascaris lumbricoides infestation can lead to serious complications because of the wander lust of the worms. Complications such as intestinal obstruction, volvulus, gangrene, pancreatitis, biliary obstruction, cholangiohepatitis and liver abscess have been reported to occur. We report a case where ascaris was seen blocking jejunostomy tube.
