1. Barium study
Barium is opaque to x-ray. In a barium study, the gastrointestinal (GI) tract is filled with barium before an x-ray is taken. Upper GI Series: * the procedure: Upper GI series involves the swallowing of barium containing liquid before x-ray is taken. The organs examined are: throat, esophagus, stomach and small bowel to diagnose esophageal cancer, reflux, hiatus hernia, gastric cancer, gastritis, and peptic ulcers. * alternative courses of action: gastroscopy, CT of chest and upper abdomen * material effects, risks and side effects: aspiration of the barium; constipation or obstruction of the bowel if the barium dries up inside the small and large intestines. Barium Enema: * the procedure: Barium enema (also known as lower GI series) involves the introduction of barium containing fluid via the rectum to diagnose rectal cancer, diverticular diseases, and polyps. * alternative courses of action: sigmoidoscopy, colonoscopy, CT scan of abdomen and pelvis * material effects, risks and side effects: fasting and cleaning the bowel with fluid and medication; sensation of bloating and potential of perforation of the colon during the procedure; barium stool impaction after the procedure.

2. Diverticulate
Having short offshoots approximately at right angles to the main stem.

3. Diverticulitis
An inflammation of the diverticula , which can cause extreme pain and sometimes fever.

4. Diverticulitis
Diverticulitis is inflammation and complications involving diverticula, the small pouches formed at weak points in the muscular coat of the intestinal tract.

5. Diverticulosis
Diverticulosis is the condition of the existence of diverticula, small pouches formed at weak points in the muscular coat of the digestive tract.

6. Diverticulum (pl. diverticula)
A diverticulum is a pouch or a sac formed at weak points in the muscular coat of the digestive tract (especially the small intestine). Inflammation of the diverticula is called diverticulitis.

7. Diverticulum (pl. diverticula)
A small sac-like structure that sometimes forms in the walls of the intestines; diverticula can trap particles of food (especially small seeds and undigested grains) and become very inflammed and painful (this condition is called diverticulitis).

8. Gastroscopy
This is the examination of the esophagus, stomach and the duodenum with a flexible fiberoptic tube which is passed through the mouth. Direct visual inspection can identify hiatus hernia, esophageal diverticula, inflammation, ulcers and tumors of the esophagus, stomach and duodenum. Biopsy of suspicious lesions can be done and microscopic examination of these biopsies can help to diagnose ulcer and tumor. Material effects, risks and side effects: perforation of esophagus, stomach, and duodenum; bleeding from biopsied site; aspiration pneumonia.
