The most common position of the uterus is anteverted (cervix angles forward) and anteflexed (body is flexed forward). The position of the uterus in the adult is liable to considerable variation, depending chiefly on the condition of the bladder and rectum. Adnexa: In gynecology, the appendages of the uterus, namely the ovaries, the Fallopian tubes, and the ligaments that hold the uterus in place.
Colorectal cancer (also known as colon cancer, rectal cancer or bowel cancer) is the development of cancer in the colon or rectum (parts of the large intestine). It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. People with HNPCC tend to develop colon cancer before age 50. Familial adenomatous polyposis (FAP). FAP is a rare disorder that causes you to develop thousands of polyps in the lining of your colon and rectum. People with untreated FAP have a greatly increased risk of developing colon cancer before age 40.
A cyst in the ear lobe is opened and drained in this short procedural video. The recording shows the small incision and expression of the cyst contents in an ear, nose, and throat context. It is shared as a clinical example for students interested in minor procedures of the external ear.
Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).
During surgery to repair the hernia, the bulging tissue is pushed back in. Your abdominal wall is strengthened and supported with sutures (stitches), and sometimes mesh. This repair can be done with open or laparoscopic surgery. You and your surgeon can discuss which type of surgery is right for you.

Rapid, practiced maneuvers are essential in this situation. For obstetric training purposes. For learning purposes only — not medical advice.
In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
Removal of a blackhead from the face is shown in this skincare procedure video. The recording demonstrates the extraction technique used to clear the blocked pore on the skin. It is presented as a dermatology and skin care education example for viewers interested in facial treatments.
Endoscopic retrograde cholangiopancreatography, or ERCP, is a specialized technique used to study the bile ducts, pancreatic duct and gallbladder. Ducts are drainage routes; the drainage channels from the liver are called bile or biliary ducts. The pancreatic duct is the drainage channel from the pancreas.

A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done.
An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body. (This also happens to sperm that are not ejaculated after a while, regardless of whether you have had a vasectomy.) Sperm are made in the testicles. They pass through two tubes called the vasa deferentia to other glands and mix with seminal fluids to form semen. Vasectomy blocks each vas deferens and keeps sperm out of the seminal fluid. The sperm are absorbed by the body instead of being ejaculated.
The goal of a decompression surgery is usually to relieve pain caused by nerve root pinching. There are two common causes of lumbar nerve root pressure: from a lumbar herniated disc or lumbar spinal stenosis. This type of pain is usually referred to as a radiculopathy, or sciatica. A decompression surgery involves removing a small portion of the bone over the nerve root and/or disc material from under the nerve root to relieve pinching of the nerve and provide more room for the nerve to heal. The most common types of decompression surgery are microdiscectomy and laminectomy.
This ophthalmology video shows the removal of a parasitic worm from a patient's eye. Ocular parasitic infestations are uncommon, and extraction must be performed carefully to protect the surrounding structures of the eye and preserve the patient's vision.
