Correct answer:

An Ascaris-lumbricoides-worm in the common bile duct

An Ascaris lumbricoides-worm in the bile duct - and coming out through the Papilla Vater

Ascariasis A disease caused by Ascaris lumbricoides, a parasitic roundworm, the largest of the human intestinal nematodes. This is the most common parasitic worm disease in the world, very prevalent in tropical regions but rarely found also in our country. In the United States about 4 million people are infected. The adult female worm can be over 30 cm long and 2-6 mm wide. The female worm produces 200.000 eggs per day. The eggs (ova) are leave the body in the stools and they can be viable on the soil for years. After infective eggs are swallowed, the larvae hatch, invade the intestinal wall, and are carried via the blood circulation to the lungs . The larvae mature further in the lungs, penetrate the alveolar walls, ascend the bronchial tree to the throat, and are swallowed, once again. In the small instestine they then develop into adult worms Upon reaching the small intestine, they develop into adult worms. The patient can be completely free of symptoms, but in the larvae stage the infection can cause peritonitis or pneumonia and in the worm stage it can cause dyspeptic symptoms and weight loss and bowel obstruction especially in children. Cholangitis and pancreatitis can be caused by worms in the bile or pancreatic ducts. Drug treatment is effective, the two most commonly used drugs are mebendazole and piperazine. Good hygiene is the most important prevention. Ascaris lumbricoides A parasitic roundworm that causes Ascariasis.

Comments:

Am doing a presentation on colon cancer for my medical terminology course. Mind you I am just a beginner in the health care field. I hope to be a Registered Nurse or maybe even a medical doctor one day. Really enjoyed your pictures(slide show) of colon cancer. I am a very visual person and it really helped me out. I am going to tell the class about your website in my oral presentation. I think they will enjoy it too.

This is an ascaris lumbricoides infection causing obstruction of the common bile duct, and may lead to simptoms like stones on the common bile duct or even cholangitis.
