2 DEFINITION of Gastrointestinal (GI) Bleeding refers to any bleeding that starts in the gastrointestinal tract, which extends from the mouth to the anus. refers to any bleeding that starts in the gastrointestinal tract, which extends from the mouth to the anus. can occur from abnormal blood clotting can occur from abnormal blood clotting can be caused by vitamin K deficiencies and thrombocytopenia — a drop in platelets (the blood cells that normally initiate the clotting process). can be caused by vitamin K deficiencies and thrombocytopenia — a drop in platelets (the blood cells that normally initiate the clotting process). The amount of bleeding can range from nearly undetectable to acute, massive, and life threatening. The amount of bleeding can range from nearly undetectable to acute, massive, and life threatening.

3 SITE Divided into: Upper GI bleeding: The upper GI tract is located between the mouth and the upper part of the small intestine.

5 COMMON CAUSES Some of the possible causes of GI bleeding include: Anal FissureGastric (stomach) ulcer Aorto-enteric fistulaHemorrhoids Arterio-venous malformations (angiodysplasias) Bleeding diverticulum Ischemic bowel Intestinal polyps Cancer of the small intestineIntestinal obstruction (twisted bowel) Celiac sprueIntestinal vasculitis Colon cancerIntussusception Cow's milk allergyMallory-Weiss tear Crohn’s diseaseMeckel’s diverticulum Dieulafoy's lesionNosebleed Duodenal ulcerPortal hypertensive gastropathy DysenteryRadiation injury to the bowel (infectious diarrhea that causes bleeding) Ruptured appendicitis Esophageal varicesStomach cancer EsophagitisUlcerative colitis

6 Upper Gastrointestinal Bleeding Upper GI bleeding originates in the first part of the GI tract - the esophagus, stomach, or duodenum (first part of the intestine). Upper GI bleeding originates in the first part of the GI tract - the esophagus, stomach, or duodenum (first part of the intestine). Upper GI bleeding is caused by one of the following: Upper GI bleeding is caused by one of the following: –Peptic ulcers –Gastritis –Esophageal varices –Mallory-Weiss tears

7 Lower Gastrointestinal Bleeding Lower GI bleeding originates in the portions of the GI tract farther down the digestive system-the segment of the small intestine farther from the stomach, large intestine, rectum, and anus.

15 PREVENTION You can prevent some causes of gastrointestinal bleeding. You can prevent some causes of gastrointestinal bleeding. Avoid foods and factors, such as alcohol and smoking, that increase gastric secretions. Avoid foods and factors, such as alcohol and smoking, that increase gastric secretions. Eat a high-fiber diet to increase the bulk of the stool, which helps prevent diverticulosis and hemorrhoids.

21 Intussusception - x-ray: Abdominal x-ray showing an intestinal condition in which a loop of bowel has slipped into another section of bowel called INTUSSUSCEPTION.  causing swelling, reduced blood flow, obstruction, and tissue damage.  Intussusception requires emergency treatment (barium enema or surgery) to prevent intestinal tissue death (necrosis), intestinal perforation, peritonitis, and death.

22 Volvulus - x-ray: Patient with a twisted bowel (volvulus).

23 Normal anatomy: The Gastrointestinal Tract starts at the mouth, which leads to the esophagus, stomach, small intestine, colon, & finally, the rectum and anus. The GI tract is a long, hollow, muscular tube through which food passes & nutrients are absorbed.

24 Indication: Bleeding from the GI tract is a common medical problem. Patients usually notice either dark red blood or bright red blood in their stool. Ulcers of the stomach and duodenum are common causes of bleeding from the upper GI tract. Bleeding can also occur in the lower GI tract (colon). Diverticular bleeding is a common cause of lower GI bleeding.

25 ENDOSCOPY Procedure, part 1 The first step in the treatment of GI bleeding is to locate the source of the bleeding. Patients who have lost significant amounts of blood are transfused with blood. Next, an endoscopy is used to locate the source of the bleeding. Upper endoscopy is generally performed first, and if no bleeding source is located, then lower endoscopy is performed. During an endoscopy, the patient is usually sedated but awake.

26 Procedure, part 2 In many cases, GI bleeding will stop on its own, with no treatment. In other cases, treatment can be provided with the endoscope, most often in the form of cautery (electrocoagulation) of the site of bleeding.

27 Procedure, part 3: If the bleeding cannot be stopped using the endoscope, surgery may be required. The bleeding segment of intestine or stomach is removed. However, most cases of GI bleeding are managed succesfully with endsocopy.

48 Acute Variceal Bleed Exact site of the bleeding of acute variceal bleeding Endoscopy is an essential step in the diagnosis and treatment of acute variceal bleeding

49 Endoscopic Variceal Ligation (Banding) ENDOSCOPIC VARICEAL LIGATION is like rubber-band ligation of hemorrhoids Esophageal mucosa and submucosa containing varices are ensnared, causing subsequent strangulation, sloughing, and eventual fibrosis, resulting in obliteration of the varices. Endoscopic ligation requires placement of an opaque cylinder over the end of the endoscope. This decreases the endoscopic field of view and may allow pooling of blood. Thus, in patients with active bleeding, visualization may be impaired more with ligation than with sclerotherapy. Local complications are less common with ligation compared to sclerotherapy.
