Who Needs an Upper Endoscopy?
Who Needs an Upper Endoscopy? samer kareem 4,127 Views • 3 years ago

When is endoscopy used? Endoscopes were first developed to look at parts of the body that couldn’t be seen any other way. This is still a common reason to use them, but endoscopy now has many other uses too. It’s often used in the prevention, early detection, diagnosis, staging, and treatment of cancer. To prevent and screen for cancer Some types of endoscopes are used to look for cancer in people who have no symptoms. For example, colonoscopy (KO-lun-AH-skuh-pee) and sigmoidoscopy (SIG-moid-AH-skuh-pee) are used to screen for colon and rectal cancer. These procedures can also help prevent cancer because they let doctors find and remove polyps (growths) that might become cancer if left alone. To find cancer early Endoscopy can sometimes be used to find cancer early, before it has had a chance to grow or spread. Looking for causes of symptoms When people go to the doctor with certain symptoms, endoscopy can sometimes be used to help find a cause. For instance: Laryngoscopy to look at the vocal cords in people with long-term hoarseness Upper endoscopy in people having trouble swallowing Colonoscopy in people with anemia (low red blood cell counts) with an unknown cause Colonoscopy in people with blood in their stool Looking at problems found on imaging tests Imaging tests such as x-rays and CT scans can sometimes show physical changes within the body. But these tests may only give information about the size, shape, and location of the problem. Doctors use endoscopes to see more details, like color and surface texture, when trying to find out what’s going on. Newer methods of endoscopy that include high magnification are being tested to find out whether they are more useful in detecting cancer and other abnormal cells on the inner surfaces of the body. To diagnose and find out the stage (extent) of cancer To get a tissue sample Going one step further, most types of endoscopes have tools on the end that the doctor can use to take out small tissue samples. This procedure is called a biopsy (BY-op-see). Samples can be taken from suspicious areas and then looked at under a microscope or tested in other ways to see if cancer is there. A biopsy is usually the best way to find out if a growth or change is cancer or something else. Getting a closer look In some cases endoscopes are used to help find out how far a cancer has spread. Thoracoscopy (THOR-uh-KAHS -kuh-pee) and laparoscopy (LAP-uh-RAHS-kuh-pee) can be very useful in finding out if cancer has spread into the thorax (chest) or abdomen (belly). The surgeon can look into these places making only a small incision (cut) in the skin.

Post-Menopausal Bleeding
Post-Menopausal Bleeding samer kareem 15,753 Views • 3 years ago

Menopause is the end of menstruation. In clinical terms, you reach menopause when you haven't had a period for 12 months. Vaginal bleeding after menopause isn't normal and should be evaluated by your doctor. For instance, postmenopausal vaginal bleeding can be caused by: Cancer of the uterus, including endometrial cancer and uterine sarcoma Cancer of the cervix or vagina Thinning of the tissues lining the uterus (endometrial atrophy) or vagina (vaginal atrophy) Uterine fibroids Uterine polyps Infection of the uterine lining (endometritis) Medications such as hormone therapy and tamoxifen Pelvic trauma Bleeding from the urinary tract or rectum Excessive overgrowth of the cells that make up the lining of the uterus (endometrial hyperplasia) The cause of your bleeding may be entirely harmless. However, postmenopausal bleeding could result from something serious, so it's important to see your doctor promptly.

Prostate Biopsy

Prostate biopsy is a procedure in which small hollow needle-core samples are removed from a man's prostate gland to be examined microscopically for the presence of cancer. It is typically performed when the result from a PSA blood test rises to a level that is associated with the possible presence of prostate cancer.

Mastectomy

Latest Advances and Treatments for Kidney Stones
Latest Advances and Treatments for Kidney Stones samer kareem 8,736 Views • 3 years ago

Treatment for kidney stones varies, depending on the type of stone and the cause. Small stones with minimal symptoms Most kidney stones won't require invasive treatment. You may be able to pass a small stone by: Drinking water. Drinking as much as 2 to 3 quarts (1.9 to 2.8 liters) a day may help flush out your urinary system. Unless your doctor tells you otherwise, drink enough fluid — mostly water — to produce clear or nearly clear urine. Pain relievers. Passing a small stone can cause some discomfort. To relieve mild pain, your doctor may recommend pain relievers such as ibuprofen (Advil, Motrin IB, others), acetaminophen (Tylenol, others) or naproxen sodium (Aleve). Medical therapy. Your doctor may give you a medication to help pass your kidney stone. This type of medication, known as an alpha blocker, relaxes the muscles in your ureter, helping you pass the kidney stone more quickly and with less pain. Large stones and those that cause symptoms Kidney stones that can't be treated with conservative measures — either because they're too large to pass on their own or because they cause bleeding, kidney damage or ongoing urinary tract infections — may require more extensive treatment. Procedures may include: Using sound waves to break up stones. For certain kidney stones — depending on size and location — your doctor may recommend a procedure called extracorporeal shock wave lithotripsy (ESWL). ESWL uses sound waves to create strong vibrations (shock waves) that break the stones into tiny pieces that can be passed in your urine. The procedure lasts about 45 to 60 minutes and can cause moderate pain, so you may be under sedation or light anesthesia to make you comfortable. ESWL can cause blood in the urine, bruising on the back or abdomen, bleeding around the kidney and other adjacent organs, and discomfort as the stone fragments pass through the urinary tract. Surgery to remove very large stones in the kidney. A procedure called percutaneous nephrolithotomy (nef-row-lih-THOT-uh-me) involves surgically removing a kidney stone using small telescopes and instruments inserted through a small incision in your back. You will receive general anesthesia during the surgery and be in the hospital for one to two days while you recover. Your doctor may recommend this surgery if ESWL was unsuccessful. Using a scope to remove stones. To remove a smaller stone in your ureter or kidney, your doctor may pass a thin lighted tube (ureteroscope) equipped with a camera through your urethra and bladder to your ureter. Once the stone is located, special tools can snare the stone or break it into pieces that will pass in your urine. Your doctor may then place a small tube (stent) in the ureter to relieve swelling and promote healing. You may need general or local anesthesia during this procedure. Parathyroid gland surgery. Some calcium phosphate stones are caused by overactive parathyroid glands, which are located on the four corners of your thyroid gland, just below your Adam's apple. When these glands produce too much parathyroid hormone (hyperparathyroidism), your calcium levels can become too high and kidney stones may form as a result. Hyperparathyroidism sometimes occurs when a small, benign tumor forms in one of your parathyroid glands or you develop another condition that leads these glands to produce more parathyroid hormone. Removing the growth from the gland stops the formation of kidney stones. Or your doctor may recommend treatment of the condition that's causing your parathyroid gland to overproduce the hormone.

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,178 Views • 3 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.
