URGENT COLONOSCOPY IN LOWER INTESTINAL BLEEDING
Summary
Emergency colonoscopy without bowel preparation is safe and effective for diagnosing intestinal bleeding. This procedure helps identify bleeding sources like diverticula and cancer, even without prior cleansing.
Area of Science:
- Gastroenterology
- Endoscopy
Background:
- Intestinal bleeding diagnosis often relies on colonoscopy.
- Bowel preparation can delay emergency procedures.
Purpose of the Study:
- To compare the diagnostic efficacy and safety of emergency colonoscopy without bowel preparation versus standard preparation in patients with intestinal bleeding.
Main Methods:
- A comparative cohort study of 252 patients with intestinal bleeding.
- Colonoscopy performed with (Hospital N~1) or without (Hospital N~29) prior bowel preparation.
- Exclusion of patients with anal/hemorrhoidal or gastroesophageal bleeding.
Main Results:
- No complications were reported in either group.
- Diagnostic yield varied between groups, with more findings in prepared patients.
- Differences in bleeding source identification were noted, particularly in women.
Conclusions:
- Emergency colonoscopy without bowel preparation is a safe and informative diagnostic tool for intestinal bleeding.
- It aids in identifying sources like diverticula and cancer.

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

01:22Bleeding in Fresh Concrete
595
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
