Virtual colonoscopy does not allow therapeutic maneuvers such as polyp and tumour removal or biopsy, nor visualization of lesions smaller than five millimeters; if a growth or polyp is detected using CT colonography, it would require removal during a standard colonoscopy. Surgeons have used the term pouchoscopy to refer to a colonoscopy of the ileo-anal pouch. Medical uses
Conditions that call for colonoscopies include gastrointestinal hemorrhage, unexplained changes in bowel habit and suspicion of malignancy. Colonoscopies are often used to diagnose colon polyp and colon cancer, but are also frequently used to diagnose inflammatory bowel disease. In older patients (sometimes even younger ones) an unexplained drop in hematocrit (one sign of anemia) is an indication that calls for a colonoscopy, usually along with an esophagogastroduodenoscopy (EGD), even if no obvious blood has been seen in the stool (feces).Fecal occult blood is a quick test which can be done to test for microscopic traces of blood in the stool. A positive test is almost always an indication to do a colonoscopy. In most cases the positive result is just due to hemorrhoids; however, it can also be due to diverticulosis, inflammatory bowel disease (Crohns disease, ulcerative colitis), colon cancer, or polyps. Colonic polypectomy has become a routine part of colonoscopy, allowing quick and simple removal of polyps during the procedure, without invasive surgery. Colon cancer screening
Colonoscopy is one of the colorectal cancer screening tests available to people in the US who are 45 years of age and older.
Simple assault may also involve an attempt to cause harm to another person, where that attempt does not succeed. Simple assault is typically classified as a misdemeanor offense, unless the victim is a member of a protected class, such as being a law enforcement officer. Even as a misdemeanor, an assault conviction may still result in incarceration and in a criminal record. Aggravated assault involves more serious actions, such as an assault that is committed with the intent to cause a serious bodily injury, or an assault that is committed with a deadly weapon such as a firearm. Aggravated assault is typically classified as a felony offense.Modern American statutes may define assault as including:

an attempt to cause or purposely, knowingly, or recklessly causing bodily injury to another
negligently causing bodily injury to another with a dangerous weapon (assault with a deadly weapon). causing bodily harm by reckless operation of a motor vehicle (vehicular assault). threatening another in a menacing manner. knowingly causing physical contact with another person knowing the other person will regard the contact as offensive or provocative
causing stupor, unconsciousness or physical injury by intentionally administering a drug or controlled substance without consent
purposely or knowingly causing reasonable apprehension of bodily injury in another
any act which is intended to place another in fear of immediate physical contact which will be painful, injurious, insulting, or offensive, coupled with the apparent ability to execute the act.In some states, consent is a complete defense to assault.
