The camera sends images to an external monitor so the doctor can study the inside of your colon. The doctor can also insert instruments through the channel to take tissue samples (biopsies) or remove polyps or other areas of abnormal tissue. A colonoscopy typically takes about 20 minutes to an hour.
A tracheotomy or a tracheostomy: is simply an opening surgically created through the neck into the trachea (windpipe) to allow direct access to the breathing tube and is commonly done in an operating room under general anesthesia. A tube is usually placed through this opening to provide an airway and to remove secretions from the lungs. Breathing is done through the tracheostomy tube rather than through the nose and mouth. The term “tracheotomy” refers to the incision into the trachea (windpipe) that forms a temporary or permanent opening, which is called a “tracheostomy,” however; the terms are sometimes used interchangeably.
Herniated or Ruptured Disc: Between each of the vertebre of the spine is a disc which is filled with a gel type material to cushion the connection between the vertebre. With age or injury these intervertebral discs can rupture or herniate. This herniation causes them to push against the adjacent nerves which come from the spinal cord. This can frequently cause pain, numbenss and tingling. This animated video reviews herniated disc.
Splenectomy is a surgical procedure to remove your spleen. The spleen is an organ that sits under your rib cage on the upper left side of your abdomen. It helps fight infection and filters unneeded material, such as old or damaged blood cells. With the da Vinci Surgical System, Dr. Olson operates through just a few small incisions. The da Vinci System features a magnified 3D high-definition vision system and tiny wristed instruments that bend and rotate far greater than the human hand. As a result, da Vinci enables surgeons to operate with enhanced vision, precision and control.
Total anomalous pulmonary venous return (TAPVR) is a rare congenital malformation in which pulmonary veins that return oxygen-rich blood from the lungs do not connect normally to the left atrium. Instead all four pulmonary veins drain abnormally to the right atrium. Heart models and animation were developed by the Cincinnati Children's Heart Institute in conjunction with Cincinnati Children's Critical Care Media Lab.
Cytomegalovirus (CMV) is a common virus that can infect almost anyone. Most people don't know they have CMV because it rarely causes symptoms. However, if you're pregnant or have a weakened immune system, CMV is cause for concern. Once infected with CMV, your body retains the virus for life. However, CMV usually remains dormant if you're healthy. CMV spreads from person to person through body fluids, such as blood, saliva, urine, semen and breast milk. CMV spread through breast milk usually doesn't make the baby sick. However, if you are pregnant and develop an active infection, you can pass the virus to your baby.
A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.
Acromegaly is usually caused by a noncancerous tumor. Middle-aged adults are most commonly affected. Symptoms include enlargement of the face, hands, and feet. Prompt treatment is needed to avoid serious illness. Drugs can reduce the effects of growth hormone. If needed, surgery and radiation may be used to remove tumor cells.
Although individual surgeons and centers employ different methods to insert a left ventricular assist device (LVAD), the fundamental concepts remain true for all. That is, most devices use the apex of the left ventricle (LV) as the inflow site to the pump, which subsequently gives off an outflow graft to the aorta, thus bypassing the ailing LV. Currently available devices do not differ significantly with regard to general implantation technique. The sequence of implantation can vary also from patient to patient, depending on the particular situation. In some cases, concomitant procedures may be performed in conjunction with LVAD implantation without adversely affecting outcome.
A bowel obstruction happens when either your small or large intestine is partly or completely blocked. The blockage prevents food, fluids, and gas from moving through the intestines in the normal way. The blockage may cause severe pain that comes and goes. This topic covers a blockage caused by tumors, scar tissue, or twisting or narrowing of the intestines. It does not cover ileus, which most commonly happens after surgery on the belly (abdominal surgery). What causes a bowel obstruction? Tumors, scar tissue (adhesions), or twisting or narrowing of the intestines can cause a bowel obstruction. These are called mechanical obstructions . In the small intestine, scar tissue is most often the cause. Other causes include hernias and Crohn's disease, which can twist or narrow the intestine, and tumors, which can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part, which is called intussusception.
Eye cancers can be primary (starts within the eye) and metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow. Melanomas (choroidal, ciliary body and uveal) -Early stages has no symptoms (the person does not know there is a tumor until an ophthalmology examination). As the tumor grows, symptoms can be blurred vision, decreased vision, double vision, eventual vision loss and if they continue to grow the tumor can break past the retina causing retinal detachment.

A ventricular septal defect (VSD), a hole in the heart, is a common heart defect that's present at birth (congenital). The hole occurs in the wall that separates the heart's lower chambers (septum) and allows blood to pass from the left to the right side of the heart. The oxygen-rich blood then gets pumped back to the lungs instead of out to the body, causing the heart to work harder. A small ventricular septal defect may cause no problems, and many small VSDs close on their own. Larger VSDs need surgical repair early in life to prevent complications.
This video: Pericarditis is swelling and irritation of the pericardium, the thin sac-like membrane surrounding your heart. Pericarditis often causes chest pain and sometimes other symptoms. The sharp chest pain associated with pericarditis occurs when the irritated layers of the pericardium rub against each other. Pericarditis usually begins suddenly but doesn't last long (acute). When symptoms develop more gradually or persist, pericarditis is considered chronic. Most cases are mild and usually improve on their own. Treatment for more-severe cases may include medications and, rarely, surgery. Early diagnosis and treatment may help to reduce the risk of long-term complications from pericarditis.
