Barium Enema Glossary of Terms

The following are health and medical definitions of terms that appear in the Barium Enema article.

Abdomen: The belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs.

Abdominal: Relating to the abdomen, the belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs.
See the entire definition of Abdominal

Abdominal cavity: The cavity within the abdomen, the space between the abdominal wall and the spine.
See the entire definition of Abdominal cavity

Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).

Abscess: A local accumulation of pus anywhere in the body. The following are some examples of abscesses:

  1. A skin abscess is better known as a common boil;
  2. A peritonsillar abscess is a persistent collection of pus behind the tonsils; and
  3. A perianal abscess is a pool of pus that forms next to the anus, often causing considerable tenderness and swelling in that area and pain on sitting down and on defecating.

Anatomy: The study of form. Gross anatomy involves structures that can be seen with the naked eye. It is as opposed to microscopic anatomy (or histology) which involves structures seen under the microscope. Traditionally, both gross and microscopic anatomy have been studied in the first year of medical school in the U.S. The most celebrated textbook of anatomy in the English-speaking world is Gray's Anatomy, still a useful reference book. The word "anatomy" comes from the Greek ana- meaning up or through + tome meaning a cutting. Anatomy was once a "cutting up" because the structure of the body was originally learned through dissecting it, cutting it up. The abbreviation for anatomy is anat.

Anus: The opening of the rectum to the outside of the body.
See the entire definition of Anus

Barium: 1. A metallic element belonging to the alkaline earths with an atomic number of 56 and an atomic weight of 137.34. The symbol for barium is Ba.
2. In medicine, refers to a chalky solution of barium used to coat the inside of organs so that they will show up on an x-ray.
See also: Barium enema; Barium swallow.

Barium enema: A series of x-rays of the lower intestine (colon) and rectum that are taken after the patient is given an enema with a white, chalky solution that contains barium. The barium outlines the intestines on the x-rays. These x-rays permit the detection of colon and rectal abnormalities including diverticulosis, diverticulitis, abnormal colon movement, dilation (widening) of the colon, polyps and cancers of the colon and rectum.
See the entire definition of Barium enema

Bowel: Another name for the intestine. The small bowel and the large bowel are the small intestine and large intestine, respectively.
See the entire definition of Bowel

Catheter: A thin, flexible tube. For example, a catheter placed in a vein provides a pathway for giving drugs, nutrients, fluids, or blood products. Samples of blood can also be withdrawn through the catheter.
See the entire definition of Catheter

Colon: The part of the large intestine that runs from the cecum to the rectum as a long hollow tube that serves to remove water from digested food and let the remaining material, solid waste called stool, move through it to the rectum and leave the body through the anus. .
See the entire definition of Colon

Colonic: 1. See: Colonic (adjective). 2. See: Colonic (noun).

Contrast: Short for "contrast media." Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue.

Dilation: The process of enlargement, stretching, or expansion. The word "dilatation" means the same thing. Both come from the Latin "dilatare" meaning "to enlarge or expand."

Distention: The state of being distended, enlarged, swollen from internal pressure.
See the entire definition of Distention

Diverticulitis: Inflammation of the diverticula (small outpouchings) along the wall of the colon, the large intestine. (One outpouching is a diverticulum; two or more are diverticula).
See the entire definition of Diverticulitis

Diverticulosis: Diverticulosis is the condition of having diverticula, small outpouchings from the large intestine, the colon. (One outpouching is a diverticulum; two or more are diverticula).
See the entire definition of Diverticulosis

Double contrast barium enema: A series of x-rays of the colon and rectum taken after the patient is given an enema, followed by an injection of air. The barium outlines the intestines on the x-rays, allowing many abnormal growths to be visible. See: Barium enema.

Enema: Liquid injected into the rectum. An enema may be used for therapeutic (such as to stimulate evacuation of the bowels) or diagnostic (such as imaging studies of the gastrointestinal tract - barium enema) purposes.

Fecal: Relating to the feces, the stool. The excrement discharged from the intestines.
See the entire definition of Fecal

Fetus: The unborn offspring from the end of the 8th week after conception (when the major structures have formed) until birth. Up until the eighth week, the developing offspring is called an embryo.

Hirschsprung disease: A congenital abnormality (birth defect) of the bowel in which there is absence of the ganglia (nerves) in the wall of the bowel. Nerves are missing starting at the anus and extending a variable distance up the bowel. This results in megacolon (massive enlargement of the bowel) above the point where the nerves are missing. (The nerves are needed to assist in the natural movement of the muscles in the lining of our bowels which move bowel contents through.)
See the entire definition of Hirschsprung disease

Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.
See the entire definition of Infection

Infuse: In medicine, to introduce a solution into the body through a vein. An infusion is the therapeutic introduction of a fluid other than blood into a vein. The infused fluid might, for example, be a saline (salt) solution.

Intestine: The long, tubelike organ in the abdomen that completes the process of digestion. It consists of the small and large intestines.

Large bowel: Another name for the large intestine.
See the entire definition of Large bowel

Large intestine: Comes after the small intestine. Large because it is wider than the small intestine.

Liquid diet: The Liquid diet is the restriction of solid food intake, and replacement of solid food with liquids. In hospitals, liquid diets are prescribed by doctors for a number of reasons for patients who are unable to consume solid foods. Liquid diets may be prescribed following surgery or as a preparation for certain medical procedures. Additionally, some people have injuries or medical conditions that limit their ability to eat solid foods. Most prescribed liquid diets allow sports drinks, broth, tea, and coffee. Strained juices may also be permitted.
See the entire definition of Liquid diet

Lower GI series: Short for lower gastrointestinal series. A series of x-rays of the rectum, colon and lower section of the small intestine taken after the patient has a barium enema. Barium is a white, chalky substance that coats the organs so they will show up on the x-ray. Also called a barium enema or a barium enema x-ray.

back to top

Peritonitis: Inflammation of the peritoneum (The peritoneum is the tissue layer of cells lining the inner wall of the abdomen and pelvis). Peritonitis can result from infection (such as bacteria or parasites), injury and bleeding, or diseases (such as systemic lupus erythematosus).

Pregnant: The state of carrying a developing fetus within the body.
See the entire definition of Pregnant

Radiation: 1. Rays of energy. Gamma rays and X-rays are two of the types of energy waves often used in medicine. 2. The use of energy waves to diagnose or treat disease. See also: Irradiation.

Radiologist: A physician specialized in radiology, the branch of medicine that uses ionizing and nonionizing radiation for the diagnosis and treatment of disease.
See the entire definition of Radiologist

Radiology: The branch of medicine that uses ionizing and nonionizing radiation for the diagnosis and treatment of disease.
See the entire definition of Radiology

Rectum: The last 6 to 8 inches of the large intestine. The rectum stores solid waste until it leaves the body through the anus. The word rectum comes from the Latin rectus meaning straight (which the human rectum is not).

X-ray: 1. High-energy radiation with waves shorter than those of visible light. X-rays possess the properties of penetrating most substances (to varying extents), of acting on a photographic film or plate (permitting radiography), and of causing a fluorescent screen to give off light (permitting fluoroscopy). In low doses X-rays are used for making images that help to diagnose disease, and in high doses to treat cancer. Formerly called a Roentgen ray. 2. An image obtained by means of X-rays.

  • Related Diseases & Conditions

    • Abdominal Pain
      • 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.
    • Appendicitis
      • Appendicitis is an inflammation of the appendix. Appendicitis often causes fever, loss of appetite, and right lower quadrant abdominal pain. Delay in surgery can result in appendix rupture with potentially serious complications.
    • Intestinal Gas
      • Gas or "intestinal gas" means different things to different people. Everyone has gas and eliminates it by belching or farting (passing it through the rectum).
    • Constipation
      • Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, abuse of laxatives, hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
    • Diverticulitis (Diverticulosis)
      • Diverticulitis is a condition in which diverticuli in the colon rupture. The rupture results in infection in the tissues that surround the colon. Diverticulitis symptoms include: abdominal pain, abdominal cramps, diarrhea, constipation, and bloating. Treatment methods include prescription medications, and in some cases, diverticulitis surgery.
    • Crohn's Disease
      • Crohn's disease is a chronic inflammatory disease, primarily involving the small and large intestine, but which can affect other parts of the digestive system as well. Abdominal pain, diarrhea, vomiting, fever, and weight loss are common symptoms.
    • Ovarian Cancer
      • There are many types of ovarian cancer, epithelial carcinoma is the most common. Women with a family history of ovarian cancer have an increased risk of developing the disease. Some ovarian cancer symptoms include abdominal pain, nausea, diarrhea, constipation, and abnormal vaginal bleeding, however, they usually do not present until the disease has progressed. Early diagnosis is important for successful treatment.
    • Colon Cancer
      • 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.
    • Ulcerative Colitis
      • Ulcerative colitis is a chronic inflammation of the colon. Symptoms include abdominal pain, diarrhea, and rectal bleeding. Ulcerative colitis is closely related to Crohn's disease, and together they are referred to as inflammatory bowel disease. Treatment depends upon the type of ulcerative colitis diagnosed.
    • Irritable Bowel Syndrome (IBS)
      • IBS (irritable bowel syndrome) is a common gastrointestinal disorder involving abnormal gut contractions (motility) characterized by abdominal pain, bloating, mucous in stools, and irregular bowel habits with alternating diarrhea and constipation, symptoms that tend to be chronic and to wax and wane over the years. Treatment options include medication and lifestyle changes such as diet, exercise, and stress management to control symptoms. Also called spastic colitis, mucus colitis, nervous colon syndrome.
    • Indigestion (Dyspepsia, Upset Stomach)
      • Dyspepsia (indigestion) is a functional disease in which the gastrointestinal organs, primarily the stomach and first part of the small intestine, function abnormally. It is a chronic disease in which the symptoms fluctuate infrequency and intensity. Symptoms of dyspepsia include upper abdominal pain, belching, nausea, vomiting, abdominal bloating, early satiety, and abdominal distention (swelling). These symptoms are most often provoked by eating.
    • Colitis
      • Inflammation of the inner lining of the colon is referred to as colitis. Symptoms of the inflammation of the colon lining include diarrhea, pain, and blood in the stool. There are several causes of colitis including infection, ischemia of the colon, inflammatory bowel disease (Crohn's disease, Ulcerative colitis, or microscopic colitis). Treatment depends on the cause of the colitis.
    • Colon Polyps
      • A colon polyp is a benign tumor of the large intestine. Benign polyps do not invade nearby tissue or spread to other parts of the body. Benign polyps can easily be removed during colonoscopy and are not life threatening. If benign polyps are not removed from the large intestine, they can become malignant over time.
    • Inflammatory Bowel Disease (Intestinal Problems of IBD)
      • The inflammatory bowel diseases (IBD) are Crohn's disease (CD) and ulcerative colitis (UC). The intestinal complications of Crohn's disease and ulcerative colitis differ because of the characteristically dissimilar behaviors of the intestinal inflammation in these two diseases.
    • Carcinoid Syndrome and Carcinoid Tumor
      • A carcinoid tumor is a tumor that develops from enterochromaffin cells. The important characteristic of carcinoid tumors that sets them apart from other gastrointestinal tract tumors, is their potential to cause the carcinoid syndrome. Local symptoms may include abdominal pain, intestinal bleeding, and intestinal obstruction. However, often symptoms of the carcinoid syndrome can be more devastating than the local symptoms. There are many options for the treatment of carcinoid tumors and carcinoid syndrome.
    • Hirschsprung's Disease
      • Hirschsprung's disease (Hirschsprung), is a disease of the nerve cells of of the large intestine. The primary symptom of Hirschsprung's disease is constipation. Hirschsprung's disease is diagnosed through barium enema, and treatment is surgery.
    • Abdominal Adhesions (Scar Tissue)
      • Abdominal adhesions (scar tissue) bands of scar tissue that form between abdominal organs and tissues. Symptoms of abdominal adhesions are pelvic or abdominal pain. Abdominal adhesions on the intestines can cause bowel obstruction, which is a medical emergency. Treatment for abdominal adhesions is generally surgery to cut the adhesions away from the internal tissues and organs. There is no way to prevent abdominal adhesions.
    • Intussusception
      • Intussusception is the telescoping (prolapse) of a portion of the intestine within another immediately adjacent portion of intestine. Intussusception affects children between the ages of 3 months and 6 years of age. The causes of intussusception is not clearly understood. Symptoms of intussusception include bilious vomiting, "currant jelly stool," and colicky abdominal pain. Intussusception is an emergency requires immediate attention.
    • The Digestive System
      • 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.

Appendicitis facts

  • The appendix is a small, worm-like appendage attached to the colon.
  • Appendicitis occurs when bacteria invade and infect the wall of the appendix.
  • The most common complications of appendicitis are abscess and peritonitis.
  • The most common symptoms of appendicitis are abdominal pain, loss of appetite, nausea and vomiting, fever, and abdominal tenderness.
  • Appendicitis usually is suspected on the basis of a patient's history and physical examination; however, a white blood cell count, urinalysis, abdominal X-ray, barium enema, ultrasonography, CT scan, and laparoscopy also may be helpful in diagnosis.
  • Due to the varying size and location of the appendix and the proximity of other organs to the appendix, it may be difficult to differentiate appendicitis from other abdominal and pelvic diseases.
