The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.

Open reduction and internal fixation (ORIF) is surgery used to stabilize and heal a broken bone. You might need this procedure to treat your broken thighbone (femur). The femur is the large bone in the upper part of your leg. Different kinds of trauma can damage this bone, causing it to fracture into 2 or more pieces. This might happen to the part of the femur near your knee, near the middle of the femur, or in the part of the femur that forms part of your hip joint. In certain types of femur fractures, your femur has broken, but its pieces still line up correctly. In other types of fractures (displaced fractures), the trauma moves the bone fragments out of alignment. If you fracture your femur, you usually need ORIF to bring your bones back into place and help them heal. During an open reduction, orthopedic surgeons reposition your bone pieces during surgery, so that they are back in their proper alignment. This contrasts with a closed reduction, in which a healthcare provider physically moves your bones back into place without surgically exposing your bone.

For this surgery, your doctor makes a large incision in the abdomen to expose the aorta. Once he or she has opened the abdomen, a graft can be used to repair the aneurysm. Open repair remains the standard procedure for an abdominal aortic aneurysm repair. Endovascular aneurysm repair (EVAR).

Absence seizures involve brief, sudden lapses of consciousness. They're more common in children than adults. Someone having an absence seizure may look like he or she is staring into space for a few seconds. This type of seizure usually doesn't lead to physical injury. Absence seizures usually can be controlled with anti-seizure medications. Some children who have them also develop other seizures. Many children outgrow absence seizures in their teens.

This surgical animation is for patient education and describes a laparoscopic colectomy, which is a type of minimally invasive surgery for colon cancer. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Instead of a big incision, the surgeon makes a few small cuts (0.5-1 centimeters) in the abdominal cavity to insert a surgical camera and instruments and perform the operation. A slightly bigger incision, about 3.5 centimeters wide, is made to remove the tumor.

When compared to traditional open surgery, laparoscopic colectomy can result in much less pain and swifter recovery. Depending on the procedure, most laparoscopic colectomy patients leave the hospital and return to normal activities more quickly than patients recovering from open surgery.

Colorectal cancer is the second leading cause of cancer death in the United States.

Bone cancer symptoms. Possible symptoms of bone cancer include: Bone pain: Pain is the most common sign of bone cancer, and may become more noticeable as the tumor grows. Bone pain can cause a dull or deep ache in a bone or bone region (e.g., back, pelvis, legs, ribs, arms).

This video: Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.

A glucagonoma is a rare tumor of the alpha cells of the pancreas that results in the overproduction of the hormone glucagon. Alpha cell tumors are commonly associated with glucagonoma syndrome, though similar symptoms are present in cases of pseudoglucagonoma syndrome in the absence of a glucagon-secreting tumor.

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.

An epidural abscess is a collection of pus (infected material) between the outer covering of the brain and spinal cord and the bones of the skull or spine. The abscess causes swelling in the area. Spinal cord abscess (SCA) is a rare condition capable of causing permanent damage to the spinal cord. Abscesses are caused when injured tissue becomes infected. The body's immune system sends white blood cells to help fight off the infection. They begin to fill the damaged tissue, causing pus to build up.

Hip Resurfacing Surgery Videos Welcome to the website of the Asian Regional Center for Hip Resurfacing (ARCH) is a specialized surgical center in Apollo Speciality Hospital Chennai. More than 1350 Hip Resurfacing Surgeries have been performed so far. Asian Regional Center for Hip Resurfacing is the first specialized resurfacing center in Asia. Patients with arthritis and hip pain travel from all over the world travel to ARCH for hip surgery. Hip Resurfacing Surgery has revolutionized hip arthroplasty especially for younger and active patients. Unlike conventional Total Hip Replacement (THR) the hip resurfacing conserves the bone in the hip which would be crucial in younger patients. No restrictions are imposed on the resurfaced hip and the patient can participate in any professional or recreational activity after the surgery.
