Gallbladder Removal Surgery (Laparoscopic Cholecystectomy)
Gallbladder Removal Surgery (Laparoscopic Cholecystectomy) Surgeon 482 Views • 3 years ago

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.

Esophageal Manometry
Esophageal Manometry samer kareem 2,070 Views • 3 years ago

Esophageal manometry is a test used to measure the function of the lower esophageal sphincter (the valve that prevents reflux of gastric acid into the esophagus) and the muscles of the esophagus (see diagram). This test will tell your doctor if your esophagus is able to move food to your stomach normally.

There are three main types of lung cancer. Knowing which type you have is important because it affects your treatment options and your outlook (prognosis). If you aren’t sure which type of lung cancer you have, ask your doctor so you can get the right information.

Dental Implant

If you are self-conscious because you have missing teeth, wear dentures that are uncomfortable or don't want to have good tooth structure removed to make a bridge, talk to your dentist to see if dental implants are an option for you. Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.

Tubular Breast Deformity (Pre-Operation)
Tubular Breast Deformity (Pre-Operation) Stuart Linder 4,557 Views • 3 years ago

Tuberous breast deformity is a congenital breast anomaly that becomes manifest at the time of puberty and breast development. The three components of tubular deformity usually include, pseudoherniation of breast tissue into the nipple areolar complex, poorly defined inframammary fold and flattening of the lower pole of the breast which leads to a conical tubular shape.

Wilson's Disease
Wilson's Disease samer kareem 3,394 Views • 3 years ago

Wilson's disease is a rare inherited disorder that causes too much copper to accumulate in your liver, brain and other vital organs. Symptoms typically begin between the ages of 12 and 23. Copper plays a key role in the development of healthy nerves, bones, collagen and the skin pigment melanin. Normally, copper is absorbed from your food, and any excess is excreted through bile — a substance produced in your liver. But in people with Wilson's disease, copper isn't eliminated properly and instead accumulates, possibly to a life-threatening level. When diagnosed early, Wilson's disease is treatable, and many people with the disorder live normal lives.

Treatment Options for Breast Cancer samer kareem 29,202 Views • 3 years ago

For both DCIS and invasive cancer, radiation therapy to the remaining breast tissue is generally recommended after surgery. A lumpectomy may also be called breast-conserving surgery, a partial mastectomy, quadrantectomy, or a segmental mastectomy. A mastectomy is the surgical removal of the entire breast.

Pulmonary Artery Catheterization
Pulmonary Artery Catheterization samer kareem 1,625 Views • 3 years ago

Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.

CHICKEN POX
CHICKEN POX samer kareem 1,629 Views • 3 years ago

Chickenpox (varicella) is a viral infection that causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who haven't had the disease or been vaccinated against it. Before routine chickenpox vaccination, virtually all people had been infected by the time they reached adulthood, sometimes with serious complications. Today, the number of cases and hospitalizations is down dramatically. For most people, chickenpox is a mild disease. Still, it's better to get vaccinated. The chickenpox vaccine is a safe, effective way to prevent chickenpox and its possible complications.
