HEMORRHOIDS(Piles) Bleeding and prolapse are the cardinal symptoms of hemorrhoids.Blood appears as a bright red streak or spot on the toilet tissue or on the surface of the stool, spurts at the height of straining, or drips from the anus after the stool has been expelled.Chronic blood loss may cause iron deficiency anemia.

CAUSES OF LGI BLEEDING

Diverticular disease

Diverticular disease is the most common cause of acute lower gastrointestinal bleeding.Diverticular disease is the most common cause of acute lower gastrointestinal bleeding. Sixty to 80% of bleeding diverticula are located in the right colon. Ninety percent of all diverticula are found in the left colonSixty to 80% of bleeding diverticula are located in the right colon. Ninety percent of all diverticula are found in the left colon Diverticular bleeding tends to be massive, but it stops spontaneously in 80% of patients, and the rate of rebleeding is only 25%.Diverticular bleeding tends to be massive, but it stops spontaneously in 80% of patients, and the rate of rebleeding is only 25%.

Angiodysplasia

Angiodysplasia Lesions are small vascular tufts that are formed by capillaries, veins, and venules, appearing as red dots or spider-like lesions 2 to 10 mm in diameterLesions are small vascular tufts that are formed by capillaries, veins, and venules, appearing as red dots or spider-like lesions 2 to 10 mm in diameter Lesions develop secondary to chronic colonic distention, and they have a prevalence rate of 25% in elderly patientsLesions develop secondary to chronic colonic distention, and they have a prevalence rate of 25% in elderly patients Even though angiodysplasia may be present throughout the entire colon, the most common site of bleeding is the right colon.Even though angiodysplasia may be present throughout the entire colon, the most common site of bleeding is the right colon. Recurrent minor bleeding; however, massive bleeding is not uncommon.Recurrent minor bleeding; however, massive bleeding is not uncommon.

Colon polyps and colon cancers

These disorders rarely cause significant acute LGI hemorrhage.These disorders rarely cause significant acute LGI hemorrhage. Left-sided and rectal neoplasms are more likely to cause gross bleeding than right sided lesionsLeft-sided and rectal neoplasms are more likely to cause gross bleeding than right sided lesions Right sided lesions are more likely to cause anemia and occult bleeding.Right sided lesions are more likely to cause anemia and occult bleeding. Diagnosis and treatment consists of colonoscopic excision or surgical resection.Diagnosis and treatment consists of colonoscopic excision or surgical resection.

Inflammatory bowel disease

Ulcerative colitis can occasionally cause severe GI bleeding associated with abdominal pain and diarrhea.Ulcerative colitis can occasionally cause severe GI bleeding associated with abdominal pain and diarrhea. Colonoscopy and biopsy is diagnosticColonoscopy and biopsy is diagnostic Therapy consists of medical treatment of the underlying disease;Therapy consists of medical treatment of the underlying disease; operation is required on rare operation is required on rare occasions occasions

Ischemic colitis

This disorder is seen in elderly patients with known vascular disease; abdominal pain may be postprandial and associated with bloody diarrhea or rectal bleeding. Severe blood loss is unusual but can occur.This disorder is seen in elderly patients with known vascular disease; abdominal pain may be postprandial and associated with bloody diarrhea or rectal bleeding. Severe blood loss is unusual but can occur. Abdominal films may reveal "thumbprinting", causedby submucosal edema. Colonoscopy reveals awell-demarcated area of hyperemia, edema, andmucosal ulcerations.Thesplenic flexure anddescending colonare the most common sites.Abdominal films may reveal "thumbprinting", caused by submucosal edema. Colonoscopy reveals a well-demarcated area of hyperemia, edema, and mucosal ulcerations. The splenic flexure and descending colon are the most common sites.

Hemorrhoids

Obscure GI bleeding A previously healthy 64 year old female presented with clinical signs of active GI bleeding. Upper endoscopy was normal and colonoscopy showed transported blood from small bowel.

Pathological results showed GIST with low MIB-1 proliferation index of 1%. Small erosions are noted in the adjacent mucosa explained GI bleeding.

Obscure GI Bleeding Small Bowel Causes Grouped by Age Patient’s < 25 years old –Meckel’s Diverticula Patient’s between 30 – 50 years old –Tumors Patient’s > 50 years old –Vascular ectasias 60

Small Bowel Bleeding Rare Causes Hemobilia –Neoplasm, vascular aneurysm, liver abscess, trauma, liver biopsy Hemosuccus pancreaticus –Pancreatic pseudocysts, pancreatitis, neoplasms –Erosion into a vessel with communication with PD Infections –Cytomegalovirus, histoplasmosis, Tb 61

Obscure GI Bleeding Evaluation Repeat EGD and Colonoscopy (~ 35% yield) If negative Capsule Endoscopy ( ~ 60–70% yield) If negative Repeat Capsule Endoscopy ( ~ 35% yield) If negative Double Balloon Enteroscopy ( ~ 40% yield) If negative Intraoperative Enteroscopy in selected cases
