This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

There are lots of fallacies about the missionary position being the best position for getting pregnant. With the woman on her back and her partner on top, it is thought that gravity will assist the sperm to swim upwards towards the egg.
ost of us come across this particular sign quite often. Of course, you can just jump to the numerous investigations and one after another, rule out the possible causes, finally getting to the diagnosis. For me, that’s no fun at all. Although I still don’t know whether I am going to become a surgeon or not (embarassing for me, since I’m going to be done with med-school this year), its pretty fascinating. If I were to work in a country whether investigations aren’t that expensive, I would definitely just perform a small examination and take a short history, sending off my patient to get a myriad of investigations, reporting to me after a while, with the diagnosis in his reports.
An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage when it may be easier to treat. Lung cancer may have spread by the time a person has symptoms. One reason lung cancer is so serious is because it usually is not found until it has spread and is more difficult to treat. Screening may provide new hope for early detection and treatment of lung cancer. Scientists study screening tests to find those with the fewest risks and most benefits. They look at results over time to see if finding the cancer early decreases a person's chance of dying from the disease.
