Endoscopic ultrasound (EUS) uses ultrasound and endoscopy to take pictures of the digestive tract and the surrounding tissues and organs. EUS may be useful in making several medical determinations, including:
- staging of cancers of the esophagus, stomach, pancreas and rectum,
- staging of lung cancer,
- evaluating chronic pancreatitis,
- studying gallstones and tumors in the bile duct, gallbladder, and liver,
- evaluating reasons for fecal incontinence,
- and studying submucosal lesions.
- drug reactions,
- and a lump in the skin where the IV was placed.

Gallbladder Pain: Relief, Causes, and Diet
Gallbladder pain (often misspelled "gall bladder") is generally produced by of five problems, biliary colic, cholecystitis, gallstones, and pancreatitis. Causes of gallbladder pain include intermittent blockage of ducts by gallstones or gallstone inflammation and/or sludge that also may involve irritation or infection of surrounding tissues, or when a bile duct is completely blocked. Treatment of gallbladder depends on the cause, which may include surgery.
What Causes Abdominal Pain?
Abdominal pain can have many causes that range from mild to severe. Some of these causes include bloating, gas, colitis, endometriosis, food poisoning, GERD, IBS (irritable bowel syndrome), ovarian cysts, abdominal adhesions, diverticulitis, Crohn's disease, ulcerative colitis, gallbladder disease, liver disease, and cancers. Signs and symptoms of the more serious causes include dehydration, bloody or black tarry stools, severe abdominal pain, pain with no urination or painful urination. Treatment for abdominal pain depends upon the cause.
Colon cancer (bowel 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.
Acute and Chronic Pancreatitis
Pancreatitis is a rare disease in which the pancreas becomes inflamed. There are two types of pancreatitis: acute and chronic. Symptoms of pancreatitis include abdominal pain, fever, nausea, vomiting, and a rapid pulse. Treatment of pancreatitis often requires hospitalization.
The Digestion Process (Parts, Organs, and Functions)
Digestion is the complex process of turning the 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. Learn more about digestion and the body parts that make it possible, including the mouth, pharynx, esophagus, stomach, small intestine, colon, rectum, anus, pancreas, liver, and gallbladder.
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 early symptoms. Typically, pancreatic cancer has metastasized (spread to adjacent organs, such as the liver) by the time most people receive a dignosis of pancreatic cancer. Symptoms and signs usually appear later in the course of the disease and include jaundice, back pain, nausea, weight loss, itching, and loss of appetite. Treatment depends upon the type of pancreatic cancer but may include surgery, chemotherapy, and/or radiation therapy.
Bile Duct Cancer (Cholangiocarcinoma)
Bile duct cancer (cholangiocarcinoma) is a rare type of cancer that arises from cells that line the drainage system from the liver and gallbladder to the intestine. Symptoms of bile duct cancer include jaundice, itching, weight loss, and abdominal pain. Physical examination, specialized blood tests, and imaging tests may be used to diagnose bile duct cancer. Treatment for bile duct cancer may include chemotherapy, radiation therapy, and photodynamic therapy. Bile duct cancer typically has a poor prognosis. Preventing liver damage may decrease the risk of developing bile duct cancer.
Symptoms of 12 Serious Diseases and Health Problems
Learn how to recognize early warning signs and symptoms of serious diseases and health problems, for example, chronic cough, headache, chest pain, nausea, stool color or consistency changes, heartburn, skin moles, anxiety, nightmares, suicidal thoughts, hallucinations, delusions, lightheadedness, night sweats, eye problems, confusion, depression, severe pelvic or abdominal pain, unusual vaginal discharge, and nipple changes. The symptoms and signs of serious health problems can be caused by strokes, heart attacks, cancers, reproductive problems in females (for example, cancers, fibroids, endometriosis, ovarian cysts, and sexually transmitted diseases or STDs), breast problems (for example, breast cancer and non-cancer related diseases), lung diseases (for example, chronic obstructive pulmonary disease or COPD, lung cancer, emphysema, and asthma), stomach or digestive diseases (for example, cancers, gallbladder, liver, and pancreatic diseases, ulcerative colitis, or Crohn's disease), bladder problems (for example, urinary incontinence, and kidney infections), skin cancer, muscle and joint problems, emotional problems or mental illness (for example, postpartum depression, major depression, post-traumatic stress disorder (PTSD), mania, and schizophrenia), and headache disorders (for example, migraines, or "the worst headache of your life), and eating disorders and weight problems (for example, anorexia or bulimia).
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 signs or symptoms; however, when they do occur the primary sign is biliary colic. Symptoms of biliary colic are constant pain for 15 minutes to 4-5 hours, and it may vary in intensity; nausea, severe pain that does not worsen with movement; and pain beneath the sternum. Treatment of gallstones depends upon the patient and the clinical situation.
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 lung cancers.
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.
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.
Gastroesophageal Junction Adenocarcinoma
Gastroesophageal junction adenocarcinoma is cancer that forms in the area where the esophagus joins the stomach. Having GERD and Barrett's esophagus increases one's odds of developing gastroesophageal junction adenocarcinoma. Symptoms and signs of GE junction adenocarcinoma include dysphagia, weight loss, black stool, cough, nausea, and vomiting. Treatment may include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy.
What Is a Limited Obstetrical Ultrasound?
An obstetric ultrasound or sonography is a procedure that uses high-frequency sound waves to produce pictures of a baby inside the mother’s womb. It also shows pictures of the mother's uterus and ovaries. An obstetric ultrasound is an important part of ante-natal (before the delivery of the baby) care.
How Do You Do an Obstetric Ultrasound?
Cervical cryotherapy is a medical procedure that involves freezing and destroying the abnormal tissue in the cervix (the lower part of the uterus). The procedure may cause some discomfort. Women report some cramping or pressure and a sensation of cold in the vaginal area. Some women do not feel any discomfort or pain during the procedure. It is generally a relatively painless procedure with little or no scarring in the area treated.
When Should You Have an Obstetric Ultrasound?
There are no special precautions that you need to take before coming for the ultrasound. You might be asked to drink water up to six glasses or until you feel like peeing. You would not be allowed to go to the washroom before you get your ultrasound done. Your full bladder helps the doctor to visualize your baby more clearly.
