a barium enema is a clinical manner used to examine and diagnose troubles with the human colon (huge intestine). radiographs (x-ray pics) are taken at the same time as barium sulfate, a radiocontrast agent, fills the colon thru an enema through the rectum.
the term barium enema commonly refers to a lower gastrointestinal collection, although enteroclysis (an upper gastrointestinal collection) is frequently known as a small bowel barium enema.
this check can be achieved in a health center or health center. the patient lies at the x-ray table and a preliminary x-ray is taken. the patient is then requested to lie on their facet even as a nicely lubricated enema tube is inserted into the rectum. because the enema enters the body, the patient might have the sensation that they need to have a bowel motion. the barium sulfate, a radiodense (indicates as white on x-ray) assessment medium, flows through the rectum into the colon. a massive balloon on the tip of the enema tube may be inflated to assist keep the barium sulfate inner. the flow of the barium sulfate is monitored by the health care provider on an x-ray fluoroscope screen (like a tv monitor). air can be puffed into the colon to distend it and provide higher pictures (frequently called a "double-contrast" examination). if air is used, the enema tube will be reinserted if it have been eliminated and a small amount of air could be brought into the colon, and more x-ray photographs are taken.
the affected person is generally asked to transport to exceptional positions and the table is barely tipped to get distinct views.
if there is a suspected bowel perforation, a water-soluble evaluation agent (inclusive of diatrizoate) is used as opposed to barium. the system is in any other case very similar, even though the pics can be of poorer pleasant. if a perforation exists, the evaluation will leak from the bowel to the peritoneal cavity; water-soluble material is less obscuring in comparison to barium ought to an belly incision to cast off the assessment be necessary.
thorough cleansing of the big gut is essential for correct pictures. check arrangements encompass a clean liquid weight-reduction plan or not anything at all (nihil per os or npo) after nighttime, consuming magnesium citrate or every other laxative, and warm water enemas to clear out any stool debris.
barium enemas are most usually used to check bowel fitness; they could help diagnose and examine the quantity of inflammatory bowel diseases which includes ulcerative colitis and crohn's disease. polyps may be visible, even though not removed all through the exam like with a colonoscopy— they may be cancerous. other issues along with diverticulosis (small pouches shaped at the colon wall which can turn out to be infected) and intussusception can be observed (and in positive instances the test itself can deal with intussusception). an acute appendicitis or twisted loop of the bowel will also be visible. if the image is ordinary a functional purpose along with irritable bowel syndrome (ibs) may be considered.
in a healthful colon, barium must fill the colon uniformly and display regular bowel contour, patency (must be freely open), and function.
