Hematochezia is the passage of gross blood from the rectum and usually indicates lower GI bleeding but may result from vigorous upper GI bleeding with rapid transit of blood through the intestines.
What is positive nasogastric aspirate?
Positive: visualization of red blood or coffee ground aspirate. • Negative: clear (nonbloody) aspirate.
What can cause Hematochezia?
What causes them?
- internal hemorrhoids.
- diverticular disease, such as diverticulitis.
- anal fissures.
- colon cancer.
- ischemic colitis.
- inflammatory bowel disease (IBD)
- neoplastic polyps.
- benign tumors.
What is nasogastric decompression?
By inserting a nasogastric tube, you are gaining access to the stomach and its contents. This enables you to drain gastric contents, decompress the stomach, obtain a specimen of the gastric contents, or introduce a passage into the GI tract. This will allow you to treat gastric immobility, and bowel obstruction.
What is the treatment for Hematochezia?
Treatment varies depending on the cause and may include medications such as antibiotics to treat H. pylori, ones to suppress acid in the stomach, or anti-inflammatory drugs to treat colitis.
What is meleana?
Melena refers to black tarry stools, which usually occurs as a result of upper gastrointestinal bleeding. It has a characteristic tarry colour and offensive smell, and is often difficult to flush away, which is due to the alteration and degradation of blood by intestinal enzymes.
How do you treat a dieulafoy lesion?
Endoscopic techniques may be used to treat Dieulafoy lesions. These techniques may include the use of electrical current, heat, or argon gas to cause the blood to clot; injection of medications such as epinephrine; or the placement of bands or clips to close off the blood vessels.
How is dieulafoy treated?
Surgical treatment. Surgical resection was historically the first-line treatment of Dieulafoy’s lesions, usually taking the form of gastrotomy and wide-wedge resection18 or gastrectomy. This has now been overtaken by advances in endoscopic procedures.
How is nasogastric decompression done?
For decompression, the standard tube used is a double-lumen nasogastric tube. There is a double-one large lumen for suction and one smaller lumen to act as a sump. A sump allows air to enter so that the suction lumen does not become adherent to the gastric wall or become obstructed when the stomach is fully collapsed.
What is hematochezia and what causes it?
Hematochezia is not a disease itself but it is a precursor that there is a problem in the lower gastrointestinal tract. it includes diseases like hemorrhoids, diverticulitis, recent trauma, large polyps and even colon cancer. Along with hematochezia, there are other symptoms in gastrointestinal bleeding. This includes:
What is the difference between Melena and hematochezia?
With melena, the health care team knows that the bleeding is at the upper gastrointestinal tract. Hematochezia is not a disease itself but it is a precursor that there is a problem in the lower gastrointestinal tract. it includes diseases like hemorrhoids, diverticulitis, recent trauma, large polyps and even colon cancer.
Which imaging modalities are used to diagnose hematochezia?
Radionuclide scans and angiography are two nonsurgical modalities that can be used to diagnose hematochezia. The order of use of various diagnostic modalities will depend on the following factors: Some patients without any diagnosis may experience multiple episodes of lower gastrointestinal bleeding.
How is hematochezia treated in colonic hemorrhage?
Other interventions, including angiography and surgery, are usually reserved for instances of bleeding that cannot be stabilized or allow for adequate bowel preparation for colonoscopy. We discuss the colonoscopic diagnosis, risk stratification, and definitive treatment of colonic hemorrhage in patients presenting with severe hematochezia.
