When you think of people showing up at the emergency room needing an object removed, you probably envision someone staggering in with a visible, manmade item -- such as a knife -- jutting from their body. In reality, some of the things most frequently taken out during ER visits are internal organs.
Appendicitis is one of the top reasons for an emergency room visit, and it almost always results in an appendectomy (the removal of the appendix, a vestigial organ that serves no obvious purpose in the human body, but can become dangerously inflamed).
Another common organ removal that often originates with an emergency medical visit is the gallbladder. Gallstones are the most common cause of abdominal pain in people who are admitted to an emergency room [source: University of Maryland Medical Center]. And in the case of an acute gallbladder attack, an emergency physician may recommend a cholecystectomy (surgical gallbladder removal).
Sometimes, however, it's not an organ that needs to be removed; it's a formation in the organ that's causing trouble. Kidney stones are notorious for sending people to the ER, and if they can't be passed easily, they may need to be removed surgically.
