Upon arrival at the endoscopy center, the nurse or the
doctor will discuss the procedure and answer any questions.
You will then be asked to sign a consent form indicating
you were informed about the procedure, its alternatives,
and its risks. You will undress and put on a hospital gown.
An IV will be placed in a vein and kept open with a slow
drip of IV fluid. This IV will be used to administer the
sedatives or other required medication. Anesthesia is
rarely used. You will then be taken into the procedure room
and, after the administration of the sedation, the
EUS will be carried out. Small electrode patches
will be placed on your skin for the monitoring of your
blood pressure, pulse, and blood oxygen.
Once sleepy, the special endoscope will be inserted and the procedure started.
Because of the sedation, you will only feel minimal
discomfort, if any, during the entire procedure. The physician
will observe the inside of your intestinal tract on
a TV monitor and the ultrasound image on another monitor.
The entire procedure generally takes 30 to 90 minutes
depending on the complexity and whether fine needle aspiration
(FNA) is performed.
After the procedure you will be sleepy for up to one hour and be unable
to drink or walk. Once you are fully awake, the doctor will
discuss with you and, if desired the person with you,
the findings of the procedure. Barring any rare complications, when
you are fully awake, your companion will be
able to take you home where you should rest for the
remainder of the day. Light meals and fluids are allowed.
The bloating which you may feel from the insufflated air
will only be temporary. Should your throat be mildly sore,
for a day or two, salt-water gargles will provide relieve.
You should call your doctor if concerned about your
progress or having severe pain, vomiting, passage or
vomiting of blood, chills or fever. If EUS was
particularly difficult or complicated you may be kept in
the hospital overnight. The endoscopist will discuss this
with you, when you wake up.
Abdominal pain is pain in the belly and can be acute or chronic. Causes include inflammation, distention of an organ, and loss of the blood supply to an organ. Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due
to tobacco smoke. Lung cancers are classified as either small cell or non-small
cell cancers.
Gallstones are stones that form when substances in the bile harden. Gallstones (formed in the gallbladder) can be as small as a grain of sand or as large as a golf ball. There can be just one large stone, hundreds of tiny stones, or any combination. The majority of gallstones do not cause symptoms.
Liver cancer is the fifth most common cancer in the world and the majority of patients with liver cancer will die within one year as a result. Patients with associated cirrhosis caused by chronic hepatitis B or C infections, alcohol, and hemochromatosis are at the greatest risk of developing liver cancer. Many patients with liver cancer do not develop symptoms until the advanced stages of the tumor which usually makes prognosis poor. The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, while a liver biopsy can make a definitive diagnosis. Medical treatments, including chemotherapy, chemoembolization, ablation, and proton beam therapy, are not very effective. Surgical removal of the tumor or a liver transplant may be most effective in certain cases.
Pancreatic cancer is a malignant tumor of the pancreas. Pancreatic cancer has been called a "silent" disease because early pancreatic cancer usually does not cause symptoms.
Colon cancer is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
Though the cause of stomach cancer is unknown, risk factors for stomach cancer include diet, H. pylori infection, smoking age, gastritis, stomach surgery, family history, and pernicious anemia. Symptoms include stomach discomfort, feeling full after a small meal, nausea and vomiting, and weight loss. Treatment depends upon staging and may involve surgery, radiation therapy, or chemotherapy.
Pancreatitis is a rare disease in which the pancreas becomes inflamed, occurring when digestive enzymes are activated and begin attacking the pancreas causing damage to the gland. There are two types of pancreatitis, acute and chronic. Most commonly caused by alcohol or gallstones, it can lead to bleeding in the gland, serious tissue damage, infection, and cysts. Enzymes and toxins may then enter the bloodstream and seriously injure organs, such as the heart, lungs, and kidney.
Esophageal cancer is a disease in which malignant cells form in the esophagus. Risk factors of cancer of the esophagus include smoking, heavy alcohol use, Barrett's esophagus, being male and being over age 60. Severe weight loss, vomiting, hoarseness, coughing up blood, painful swallowing, and pain in the throat or back are symptoms. Treatment depends upon the size, location and staging of the cancer and the health of the patient.
Gallbladder (gall bladder) pain can be caused by gallbladder disease such as gallstones or cholecystitis. Causes of gallbladder pain can be caused from biliary colic. Biliary colic is pain caused by gallstones trapped in the bile ducts. Cholecystitis is inflammation of the
gallbladder. Symptoms of gallbladder disease include nausea, vomiting, abdominal bloating and belching, sweating, and shortness of breath. Treatment of gallbladder pain depends on the cause.
Digestion is the complex process of turning food you eat into the energy you need to survive. The digestive process also involves creating waste to be eliminated, and is made of a series of muscles that coordinate the movement of food.
