Blood in the stool

Blood in the stool-What is blood in the stool?

Blood discharge from the anus, stool, or are all bloody stool, the color was bright red, dark or tarry, and are referred to as the blood in the stool. Blood in the stool usually found in lower gastrointestinal bleeding, especially colon and rectal bleeding, but occasionally seen in upper gastrointestinal bleeding. The color of blood in the stool depends on the site of gastrointestinal bleeding, bleeding and blood in gut residence time. Blood in the stool with skin, cats, film or other organs, bleeding, more common in patients with blood diseases and other systemic diseases. Such as leukemia, disseminated intravascular coagulation, etc., below the Treitz ligament digestive tract (including jejunum and ileum, colon and rectum) parts of the lesions caused by the bleeding, that is, lower gastrointestinal bleeding.

Blood in the stool - signsBlood in the stool, gastrointestinal bleeding (less than 500ml), you can soon be the body compensatory without causing obvious symptoms; when bleeding more than more than 800 ~ 1000ml, especially in the shorter term is lost, may have dizziness , fatigue, palpitations, pulse rate, blood pressure, pale skin, the performance of the more severe cases, shock performance. The above performance prompted for the bleeding. Bleeding patients, when symptoms, dizziness, cold sweats, heart palpitations, pale skin, pulse and blood pressure remained at normal levels prompted bleeding has stopped. When the upper gastrointestinal tract lesions bleeding, such as the large amount of bleeding, fast, short residence time of blood in the intestine can also be manifested dark anal discharge, and even fresh red blood, this situation is also easy with the lower digestive tract lesions bleeding confuse these two kinds of situations must be identified.Blood in the stool - the cause ofBlood in the stool caused by disease of blood in the stool [1] In accordance with the nature of bleeding lesions, will be the cause of blood in the stool of classified into five categories.Inflammation, ulcerative factors are as follows gastrointestinal mucosal inflammation or ulceration, mucosal congestion, edema and ulcer formation, erosion of blood vessels or increased vascular permeability, inflammation or ulceration of the small blood vessels rupture can occur throughout the blood in the stool. The common diseases are:(1) intestinal infectious diseases: bacillary dysentery, amoebic dysentery, fungal enteritis, pseudomembranous colitis, intestinal tuberculosis, colonic tuberculosis, small intestine, hookworm infection, colonic schistosomiasis, hemorrhagic necrotizing go far .(2) inflammatory bowel disease: Crohn's disease (Crohn's disease) or ulcerative colitis.(3) The radioactive colon, proctitis: mostly the pelvic malignant lesions treated with radiotherapy after local intestinal mucosal damage resulting in bleeding that often appears repeatedly, a small amount of blood in the stool.(4) ischemic colitis: more common in elderly patients with atherosclerosis, due to the mesenteric blood supply barriers to leaving the intestinal mucosal ischemia, ulceration due. Lesions in the colon more common clinical manifestations of severe abdominal pain after the solution dark red or bright red bloody stools.(5) of Behcet's disease (Behcet'sdisease): etiology of this disease is unknown, many considered to be immune vasculitis caused by the occlusion of blood vessels, leading to intestinal blood supply ulcerative disease caused by blood in the stool changed; Some scholars believe that the disease is associated with infection or genetic . Ulcers in the ileocecal by the most common, and prone to bleeding.(6) rectal solitary ulcer: the reason to cause such ulcers is not very clear, but the ulcers, erosion of blood vessels can cause bleeding.Colon (7) of stress ulcer: In recent years, found that taking non-steroidal anti-inflammatory drugs (NSAIDs), can lead to blood in the stool, or even for bleeding, and more common in elderly patients. Inflammation, ulcerative lesions is a common cause of blood in the stool. Inflammation and ulceration of the majority of the rectum and sigmoid colon can cause the mucus pus and blood will; severe ulcerative colitis, the schistosome granuloma can cause the blood will; amoebic dysentery, a common cause of the jam color or dark red bloody stools; a small number of intestinal tuberculosis or Crohn's disease can be bleeding; hemorrhagic necrotizing enteritis often discharge of dark, red or watery stools to wash the meat. In short, then blood and color, often with lesion size, location and bleeding speed.Department of bleeding, (2) vascular factors, vascular lesions of lower digestive tract, causing blood vessels to rupture or cause due to mesenteric ischemia, intestinal mucosal blood supply. The common causes are:(1) moving poor venous malformations and vascular development: gastrointestinal intestinal angiodysplasia, malformed vascular lesions caused by bleeding in the past 10 years, attention has become one of the important cause of blood in the stool. Can be divided into:① cavernous hemangioma.② intestinal mucosal angiodysplasia.③ vascular malformations. Approximately 70% of the lesions in the colon, especially the right colon or cecum common. A small number of vascular malformations in the small intestine. Blood in the stool(2) hereditary hemorrhagic telangiectasia (Ronda-Osier-Weber syndrome): This syndrome can occur in the whole digestive tract, such as prone to bleeding in the small intestine. Rare, the disease is a familial genetic disease.(3) Dieulafoy disease: The lesions occur in the stomach by the most common and the event in the small intestine or colon can cause blood in the stool. The disease is more common in elderly patients, bleeding due to submucosal blood vessels by inflammatory stimulation of the ulcers rupture caused.(4) of the rectum, colon and small intestine mucosa, varicose veins: patients with portal hypertension, collateral circulation, a very small number of patients back to the vein in the colonic mucosa can occur varicose, such as rupture can cause bloody stools. Line splenectomy and gastric fundus blood vessel cross-sectional surgery, the veins in the intestinal mucosa more prone to varicose.(5) long-distance or endurance athlete, blood in the stool: In recent years the disease increasing number of incentives to long-distance or endurance athletes such as marathon and other long-distance runner, in addition to a small number can cause the bones, muscles and heart disease, the occurrence of gastrointestinal lesions has been reported, can be expressed as the blood in the stool, blood in the stool of reasons in addition to rupture, with hemorrhoids, and abdominal visceral impact, vibration and blood redistribution lead to intestinal ischemia (immediately found blood in the stool athletes colonoscopy can be found in the intestinal mucosal hyperemia with erosion hemorrhage and formation change).(6) Wegener granulomatosis disease: Department of unexplained systemic vascular inflammatory disease, often with the nasopharynx, lung disease and necrotizing glomerulonephritis. The disease can sometimes involving the gastrointestinal tract, small intestine or colon ischemia, hemorrhage, and severe cases, intestinal perforation.(7), mesenteric vascular ischemic lesions can be seen in:① mesenteric vascular spasm.② mesenteric venous thrombosis.③ mesenteric artery embolism.(4) ischemic colitis. Mesenteric ischemia lesions may be due to shock, atherosclerosis, intravascular meningitis or secondary to associated with atrial fibrillation, heart disease (ischemic colitis in inflammation, ulcerative factors already referred to).Abdominal aortic aneurysm (8): If the ruptured abdominal aortic aneurysm perforation of the small intestine or colon, can lead to lower gastrointestinal bleeding.(9) inside and outside the formation of hemorrhoids: internal and external hemorrhoids bleeding, more than for fecal surface of blood after blood. But a few cases, internal hemorrhoids, blood can accumulate in the rectal ampulla, when the blood first discharge can be expressed as the solution dark red or bright red blood will. Hemorrhoids bleeding is one of the common cause. Blood in the stool.

Mechanical factors(A) jejunal diverticulum: bleeding is caused by inflammation of the diverticulum.(2) colonic diverticulitis or diverticular disease: multiple diverticula of the colon in the United States and Europe has become one of the important causes of blood in the stool, but rare in China colon with multiple diverticula.(3) diverticulum of Meckel (Meckel 's): occurred in the distal ileum, 70% to 85% of patients may be asymptomatic, but the most common manifestations of symptomatic hemorrhage.(4) intussusception or volvulus: intussusception occur in infants less than 10 years of age, more than 60% of adult intussusception secondary to multiple intestinal polyps or intestinal tumors. Erzhi bleeding the volvulus too long, the intestinal blood flow obstacle.(5) of the ileocecal valve prolapse: a few cases, such as the ileocecal valve prolapse, can cause bleeding occurred incarcerated.(6) colon endometriosis: endometrial tissue differences in the colonic mucosa, when the female patients with menstrual cramps can occur, bloody stools, blood in the stool when the end of the menstrual cycle ceases.(7) anal fistula and anal fissure: a few cases of anal fistula and anal fissure can cause bleeding, but generally little amount of bleeding.(8) colonoscopy line after polypectomy, small intestine or colon surgery: polypectomy, such as inadequate coagulation, surface bleeding can lead to coagulation. Intestinal surgery, bleeding is not full can also be bleeding.4 tumor factors, gastrointestinal benign and malignant tumors more, is one of the important cause of the cause of bleeding.(1) benign:① colon polyps: familial adenomatous polyposis, Gardner syndrome, Turcot syndrome, juvenile polyposis and melanin spots - multiple polyposis of the gastrointestinal tract (PJ syndrome), hyperplastic polyposis, inflammatory polyps . An important cause of blood in the stool.② small intestine leiomyoma, neurofibroma, and other, less common.(2) malignant tumors:① intestinal lymphoma: sometimes bleeding.② small bowel adenocarcinoma: rare.③ the small intestine, large intestine carcinoid tumors: cause of bleeding is rare.④ colon, rectal cancer: Is one of the common cause of lead to blood in the stool, but generally small amount of bleeding.(5) systemic disease(1) infectious diseases: typhoid fever, paratyphoid fever, epidemic hemorrhagic fever, leptospirosis, severe hepatitis or fulminant hepatic failure.(2) blood diseases: hemophilia, the abdominal allergic purpura (Henoch purpura), gastrointestinal malignant histiocytosis disease.(3) connective tissue disease: nodular polyarteritis (colon nodular periarteritis), systemic lupus erythematosus and rheumatoid arthritis involving the intestinal tract.(4) Other: such as severe sepsis, food poisoning, mercury poisoning, uremia can cause blood in the stool. In general, young children, teenagers blood in the stool, colon polyps, intussusception, Meckel diverticulum, and inflammatory diseases for the common cause; in elderly patients while inflammatory bowel disease, colon cancer, intestinal vascular The lesion is more common cause; perianal lesions such as hemorrhoids, anal fissure or fistula in the adult should not be overlooked.Blood in the stool - the physiologicalBlood in the stool. Digestive diseases(1) anal diseases: hemorrhoids bleeding is due to increased intra-abdominal pressure during defecation, leading to hemorrhoid venous plexus blood pressure, direct and hard fecal abrasions to the hemorrhoids rupture caused. Anal fissure visible pinworm infection in children cause perianal itching, scratch the infection and the formation of severe pain associated with blood in the stool during defecation, and low red. Anal fistula most often secondary to anorectal abscess, a small number of secondary intestinal tuberculosis. Around the anus, perineum, or the sacrococcygeal visible anal mouth, squeezing around the outflow of pus from the fistula.(2) inflammatory bowel disease: acute bacillary dysentery, acute hemorrhagic necrotizing enterocolitis, intestinal tuberculosis, ulcerative colitis, etc., are caused by different causes in different parts of the intestinal mucosa congestion, edema, erosion, ulcer bleeding even necrosis. Manifestations of pus and blood, the blood will be even blood will.(3) of intestinal cancer: colon, rectum, small intestine, malignant lymphoma, or cancer tissue ulceration or lymphoma tissue ulceration, and the performance of the bright red blood will bloody stools with mucus and pus. Benign tumors of the small intestine, such as less bleeding, small bowel neurofibroma, leiomyoma, adenoma, etc., but larger tumors, can cause intestinal obstruction. Intestinal hemangioma infection, rupture can cause acute bleeding.The lower digestive tract vascular lesions of the superior mesenteric artery embolism or mesenteric arterial and venous thrombosis formation, volvulus, intussusception due to intestinal mucosal ischemia, necrosis, shedding, intestinal cyanosis, edema and serous exudate, full-thickness bowel wall necrosis , a large number of bloody fluid leakage may occur diarrhea discharge of dark red bloody stools. Pathogenesis of systemic disease, see upper gastrointestinal bleeding (hematemesis and melena).

Blood in the stool - the stool bleeding what kind of harm?Stool, repeated a number of bleeding, the body will lose a lot of iron, causing iron deficiency anemia. Iron deficiency anemia, bleeding hemorrhoids caused by early generally do not have symptoms or mild symptoms, manifestations, anemia, heavy or rapid progress when a pale, languid, loss of appetite, palpitations, heart rate and physical activity, air promote, edema.
Postpartum blood in the stool of harmA. Long-term blood in the stool can cause iron deficiency anemia. Long-term blood in the stool, it is easy to make the patient's body to lose large amounts of iron, causing iron-deficiency anemia.Iron-deficiency anemia usually develops slowly, early can have no symptoms or mild symptoms, anemia heavier will appear pale, languid, loss of appetite, palpitations, rapid heart rate and physical activity and shortness of breath, swelling, etc., some patients can even be nervous system symptoms such as irritability, excitement, irritability and so on.Two. Diseases of the blood in the stool behind a lot. Postpartum blood in the stool as a common symptom, it appears that often precedes the emergence of anorectal disease. Many anorectal disease, hemorrhoids, anal fissure, rectal polyps, colon polyps, ulcerative colitis or rectal cancer are blood in the stool phenomenon.Blood in the stool - stool hurt is how
Stool hurt [3] from the symptoms of hemorrhoids, blood in the stool are the blood, the general as well as tumor prolapse, pruritus ani or anal wet phenomenon, patients over exertion, after eating spicy spicy food or alcohol is easy to attack ; anal fissure blood in the stool, while accompanied by severe pain after using sustainable period of time; enteritis blood in the stool accompanied by abdominal pain, diarrhea and other symptoms after drinking or eating spicy cold food easy to add. , Fuzhou anal Thai anorectal hospital experts suggest that stool, first professional anorectal hospital diagnosed after symptomatic treatment.

Blood in the stool - CheckThe judge bloody stool frequency and quantity of blood in the stool (1) the amount of bleeding, bloody stool frequency and quantity of blood in the stool of blood loss is estimated less accurately, but the blood will be more than the number of each volume is undoubtedly a large amount of bleeding of the indicators. In addition, if the patient is discharged a bright red or dark red blood stools, and even discharge clot is also a large amount of bleeding corroboration. Patients each time the blood will be less, fewer, or even a few days Xie 1, suggesting that the small amount of bleeding; if red blood cells in the intestine damage, hemoglobin and sulfides and the formation of tarry stool black ferrous sulfide, or stools.. Bleeding to judge whether to stop after active treatment, the frequency and quantity of blood of patients will significantly reduce, mitigate prompt bleeding when the patient a few days defecation or discharge yellow then, often prompts the bleeding has stopped. Blood in the stool diagnosis to establish the diagnosis of blood in the stool should be possible to rule out upper gastrointestinal bleeding. In general, according to the characteristics of the history, signs and bleeding can make a preliminary judgment. Ulcer disease or history of liver cirrhosis who prompted the possibility of upper gastrointestinal bleeding and inflammatory bowel disease history of prompt blood in the stool possibility. Tarry stools or black stools with vomiting, upper gastrointestinal bleeding in general are; only blood in the stool, blood in the stool of the possibility of slightly larger, but a lot of duodenal ulcer showed only blood in the stool, then, need to based on history, symptoms and the signs and blood characteristics were analyzed to determine the upper digestive tract, or blood in the stool. Upper gastrointestinal bleeding, due to the large amount of bleeding, blood in the intestine short residence time can also be dark red or bright red blood will be discharged through the anus, but patients usually have vomiting coexist, so the identification is often no difficulty. Fever, leukocytosis, blood urea nitrogen were significantly increased, often prompt a higher bleeding sites, namely the possibility of upper gastrointestinal bleeding. Identify difficulties, you can insert a nasogastric tube to the stomach, such as suction containing coffee grounds or dark red gastric juice, you are prompted for upper gastrointestinal bleeding; such as pumping out blood containing bile juice, you can exclude the digest gastrointestinal bleeding; such as aspiration of bile, and the clearest gastric juice, you can only exclude the esophagus and stomach bleeding, and still can not completely rule out duodenal bleeding. The most reliable method of identifying a gastroscopy can immediately establish or exclude upper gastrointestinal bleeding (gastroscopy reach the descending duodenum yet to see the bleeding can be ruled out, the basic upper gastrointestinal lesions).The cause of blood in the stool diagnosis based on patient history, symptoms and signs, some blood in the stool in patients, its etiology may make the initial diagnosis, for example, patients with hemorrhoids history, every time the performance drop of blood or blood with stool after a bowel movement is not mixed ( blood attached to the outside of the stool), blood is red, you should consider hemorrhoids bleeding. Younger patients, when blood is attached to the stool on the outside, not mixed with the stool should also consider the possibility of left colon polyps, inflammatory bowel disease, ulcerative lesions should be considered; patients with discharge of mucus, pus and blood, such as at the same time accompanied by tenesmus, but also consider the possibility of cancer. But diagnosis still need to rely on laboratory tests and special inspections.(1) laboratory tests: stool examination, such as found in amoeba trophozoites or schistosome eggs, it will help the diagnosis of amoebic dysentery or schistosomiasis; stool found in red blood cells, pus, prompted intestinal inflammation lesions, stool culture to identify pathogens; consider the Department of the blood disease caused by blood in the stool, should be for platelet count, clotting time, prothrombin time and clotting factor to check, where necessary, bone marrow examination.(2) digital rectal examination: blood in the stool in patients as a routine examination. Rectal examination can be found in the internal hemorrhoids, polyps or cancer and narrow lesions.Laboratory tests:(1) early after the blood in the stool, hemoglobin, red blood cell count can be no significant change, but when added to isotonic fluid volume expansion, red blood cell count, blood hemoglobin and hematocrit determination to contribute to the judgment of the blood loss. The degree of elevated blood urea nitrogen is also conducive to the judgment of the number of bleeding (called enterogenous blood urea nitrogen).Red blood cell count, hemoglobin and hematocrit is no longer reduced, or blood urea nitrogen decreased to normal, both showed the bleeding has stopped.Other laboratory examinations:1.X-ray barium meal or barium enema double contrast barium duodenum, jejunum and ileum, check or total colon examination, intestinal tuberculosis, Crohn's disease, schistosomiasis, ulcerative colitis, volvulus, the diagnosis of intussusception, polyps or cancer and other diseases. Sigmoidoscopy or colonoscopy, the rectum and sigmoid colon is the site of inflammatory lesions, polyps or cancer and other diseases, sigmoidoscopy is the diagnosis of these lesions is extremely helpful. Full colonoscopy in addition to the above diseases can be found on the descending colon, transverse colon, ascending colon and cecum of the hemorrhagic lesions diagnosis was helpful. Such as colonoscopy to the terminal ileum, but also lesions of the distal ileum, such as tuberculosis, the diagnosis of Crohn's disease, lymphoma and other diseases to help. If combined with biopsy and histological examination, can significantly improve diagnostic accuracy.Two abdominal B ultrasound or CT, MRI examination have diagnostic value in advanced colorectal cancer. Such as intra-abdominal or retroperitoneal lymph nodes, the reference value for the diagnosis of intestinal tuberculosis, lymphoma and other diseases. Angiography to check blood in the stool, underwent selective mesenteric artery catheterization angiography, clear the site of bleeding, but also conducive to the diagnosis of vascular malformations and other diseases, so unexplained blood in the stool in patients with clear bleeding site or etiology, underwent selective angiography is essential to check. Wireless capsule endoscopy (wirelesscapsuleendoscope) check in recent years, wireless capsule endoscopy (also known as capsule endoscopy) check is used in clinical, the check is non-invasive, well tolerated in patients with no adverse reactions. Capsule is slightly larger than the average drug capsules, its built-in flash units and photographic chip; reach the pylorus after capsule swallowing it takes 40min or so, check the End of the gastrointestinal tract of time the average 350min; capsule through the gastrointestinal cavity, they camera images through the abdomen of the remote control receiver signal is stored in the computer, and then on the clear images for analysis; capsule endoscopy colorectal with stool discharge (with a one-time items). Some scholars believe that after the intestinal cleansing, and then to swallow the capsule endoscopy, the advantages of more, better to get the exact parts of the capsule after the exact residence time of multi-site, to determine the lesion. The sensitivity and accuracy of this inspection technique are higher than small bowel barium enema technique, but sometimes the lesion is not an accurate positioning and a biopsy of the lesion can not be the main defects of the capsule endoscopy. Positive diagnostic rate of capsule endoscopy in occult gastrointestinal bleeding up to 80%, according to data from abroad, such as vascular malformations, polyps, tumors, Crohn's disease, ulcers, celiac disease and other diseases can be made in small intestinal disease diagnosis, therefore, some scholars believe that the routine examination was negative when the preferred capsule endoscopy for patients with gastrointestinal bleeding. Inspection fees are more expensive, thus the popularity of carrying out is still subject to certain restrictions. New enteroscope (pushenteroscopeP.E,) check is now a new type of push-enteroscopy in clinical and biopsy of the lesion, allegedly of great value to the diagnosis of the problems of small bowel diseases. New enteroscopy overcome the old-fashioned enteroscopy operational difficulties not easy at the junction of the duodenum and jejunum (flexor ligament) and other shortcomings, it is more widely used.

Blood in the stool - differentialBlood in the stool, many cause blood in the stool of the disease, the following only in respect of the common diseases briefly identify.Hemorrhoids or anal fissure, anal fistula(1) is blood in the stool one of the common causes of internal hemorrhoids are very common.(2) redness of the skin is generally red, and not mixed with faeces, do not contain mucus, in most cases the performance of stool in drops of blood in the stool of the induration, especially more susceptible.(3) anal fissure in patients with bowel movements often have pain.(4) anal visual inspection and digital examination often can be confirmed.Anoscope or proctoscope (5) to check the diagnosis, direct peering to hemorrhoids and bleeding lesions.2. Bacillary dysentery(1) the acute phase often have chills, fever, lower abdominal pain and other symptoms. Stool often as pus and blood samples each are small, often accompanied by tenesmus; chronic phase of intermittent episodes of mucus, pus and blood.(2) stool routine examination found a large number of pus cells, red blood cells and macrophages; stool culture can be found in pathogenic bacteria (Shigella), but the chronic phase stool culture-positive rate is not high, only 15% to 30%.(3) colonoscopy mucosa visible lesions were diffuse congestion, edema, ulcers and more than superficial, and the edges are often irregular.3. Amoebic dysentery(1) stool samples mostly jam, or dark red, more often accompanied by purulent mucus, patients have fever, abdominal distention, abdominal pain and tenesmus performance.(2) stool examination can be found in the piles of red blood cells and a small amount of white blood cells, such as the find of E. histolyticaHave confirmed the value of trophozoites or cysts.(3) colonoscopy examination showed mucosal hyperemia, but the edema was not significant, ulcers generally deeper, and often a small mouth end ofThe flask-like ulcers, ulcers and normal mucosa. The lesions can occur in any part of the large intestine.4. Schistosomiasis(1) history of exposure to contaminated water, usually presents with chronic diarrhea and stool pus and blood samples for blood in the stool.(2) often have other clinical manifestations of schistosomiasis, such as hepatosplenomegaly, whole blood cells decreased.(3) B-type ultrasonic inspection can be found in liver fibrosis.(4) colonoscopy shows the rectal mucosa the miliary yellow nodules, sometimes you can still see such as ulcers or polyps, rectal mucosal biopsy can be found schistosome eggs. Blood in the stool5 Ulcerative Colitis(1) is an unknown etiology and non-specific colitis disease, the lesions were recurrent, and ease the process, delayed healing. Exacerbation of abdominal pain, diarrhea, often accompanied by tenesmus. The disease is often the first violation of the rectum and sigmoid colon, and later lesions can be up and gradually spread directly to the ileocecal; a few patients the lesion from the right colon, and then gradually left the spread of semi-colon. The stool is usually pus and mucus stools, severe cases bloody stools.(2) stool examination showed red blood cells, white blood cells, but the stool repeatedly cultured without the growth of pathogenic bacteria.(3) disease activity of colonoscopy visible mucosa showed diffuse congestion, edema, superficial ulceration, mucosal fragility touch of easy bleeding; mucosal biopsy, the pathology found the glands reduced goblet cells and found that the crypt abscess , help in the diagnosis. Of persons with chronic intestinal sometimes can be found in inflammatory polyps duration of the elderly bowel wall thickening performance.(4) X-ray barium enema in the diagnosis of help can be seen in the mucosal folds disappear, colon bags disappear, such as performance.(5) The effect of antimicrobial therapy, sulfasalazine or 5 - aminosalicylic acid, glucocorticoid treatment, may alleviate the condition.6. Intussusception(1) The discharge of bloody mucus, often non-stool. The abdomen is sometimes palpable intussusception mass.(2) X-ray barium enema examination is not only a clear diagnosis, but also for therapeutic purposes.7. Rectal cancer(1) is a common cancer. Where 35-year-old patients suffering from chronic diarrhea or recurrent mucus pus and blood in stools, with tenesmus, rectal cancer may be invalid by the general anti-inflammatory therapy should be considered.(2) digital rectal examination can be found in the lesions, the diagnosis is very helpful. Rectal cancer and more irregular, hard lumps, tenderness in the intestinal wall, the mass surface is often uneven; refers to put often with mucus, pus and blood. The vast majority of rectal cancer can be found that the accused seized.(3) colonoscopy can be directly observed cancer of the shape, scope, combined with biopsy can confirm the histological diagnosis.8. Colon cancer(1) middle-aged patients, change in bowel habits, diarrhea or constipation, thinning stool, stool with mucus sepsis should be suspected and the possibility of colon cancer, a small number of blood in the stool patients showed only for the fixity of abdominal pain.(2) more than the right colon with abdominal pain, diarrhea as the main performance, stool routine examination can be found in the pus cells, red blood cells, or occult blood test was positive; left colon cancer more than the performance of thinning stool or constipation, while stool can also be accompanied by mucus or pus and blood. A small number of patients with symptoms of intestinal obstruction.(3) some cases may be palpable and the abdomen fixed mass, and tenderness.(4) advanced cases, weight loss, anemia and other manifestations.(5) colonoscopy can be found in the tumor location, size and extent of disease, combined with biopsy to confirm the diagnosis.(6) X-ray barium enema in the diagnosis of great help, especially the superior is more than a colonoscopy may cause intestinal stricture diagnosis of cancer infiltration.Rectum, colon polyp(1) is caused by a common cause of blood in the stool, especially in children and adolescents.(2) of the rectum, sigmoid or descending colon polyps, the performance is accompanied by a fresh blood in the stool outside, blood and feces mix of its features. The right colon polyps, the blood can be mixed with the stool, but when the large amount of bleeding, the blood may be dark red, the smaller amount of bleeding were melena-like performance.(3) a small number of patients with family history.(4) X-ray barium enema examination can be seen round or oval filling defect diagnosis.(5) colonoscopy polyp location, shape and number can be found, and possible biopsy to determine the pathological type of polyp

Blood in the stool - the treatment ofThe hematochezia case of blood in the stool, especially of lower gastrointestinal bleeding, should be based on history, clinical manifestations and characteristics of bleeding, careful analysis of the possible causes of bleeding. Shall immediately take effective measures to stop bleeding as soon as possible to stop the bleeding, and thus to create conditions for further search for the cause of bleeding. Blood in the stool should follow the following principles of treatment.General treatment measures beneath the bloody shock should rest in bed, to pillow supine, give oxygen. Close observation of consciousness, breathing and pulse, blood pressure and other vital signs, and should observe the amount and color of the blood in the stool, record urine. Add volume large amount of blood in the stool, obvious anemia or shock, should be positive to add volume. Plasma substitutes or whole blood is better, to correct shock.(2) application of hemostatic agents(1) 6% to 8% of the noradrenaline (norepinephrine) solution repeatedly enema or ice brine repeated enema (winter is not appropriate to use), may play a role in hemostasis, but also play a role in intestinal cleansing, to prepare for colonoscopy.(2) thrombin or baiyao of White perilous powder Chinese herbal medicine dissolved in saline enema, sometimes can play a hemostatic effect.(3) conventional intravenous hemostatic agents, such as Etamsylate (bleeding min), vitamin K1 Aminomethylbenzoic, acid (anti-fibrinolytic aromatic acid), 6 - aminocaproic acid or blood clotting enzyme (reptilase).(4) conditions by infusion of cryoprecipitate (containing various clotting factors) or platelets clotting composition.(5) the superior mesenteric or inferior mesenteric artery selective (or super-selective) angiography, found the bleeding site, the choice of the pituitary vasopressin or Terry pressure hormone injected into the bleeding vessel, effective hemostasis rate of up to 80% ~~ more than 90%.Actively clear the bleeding site or cause of(1) the superior mesenteric artery selective angiography: the check is in the process of bleeding can be carried out. Great help to clear the site of bleeding, and sometimes also a clear cause.(2) colonoscopy: in a basic stop bleeding after colonoscopy, rectal lesions have confirmed the value of the entire colon (including ileocecal junction and the terminal ileum). The discovery of the hemorrhagic foci endoscope using a variety of methods to stop bleeding.(3) X-ray barium enema: the bleeding stopped after a barium small bowel or barium enema, can assist in the detection of a variety of cause bleeding of the primary disease.(4) For difficult cases, capsule endoscopy or new colonoscopy to confirm the diagnosis as soon as possible. Still can not stop bleeding after surgical treatment of minorities by the examination and treatment or can not establish the diagnosis, possible surgical exploration.Blood in the stool - the day-to-day preventionDaily prevention of blood in the stool should do the following:

(1) to develop regular bowel habits, stool thin paste better.

(2) reduce the attitude of the increase in abdominal pressure, as squatting, hold your breath. Avoid sedentary, long-established, long lines and overwork.

(3) eat Xin hot, greasy, coarse, multi-residue foods, avoid alcohol, coffee.

(4) eat more bowel heat, moisturize and nourish, purge the hemostatic effects of food, such as Health and pear juice, Ouzhi, water chestnuts, juice, reed rhizome juice, celery juice, carrot, turnip (cooked food), bitter gourd, eggplant, cucumber, spinach, day lily flowers, cabbage, egg yolk, apples, figs, bananas, black sesame, walnut meat, jelly and so on.

(5) The mood is cheerful, not Yu Nu flare up. Not wide mood, irritability and depression make the mucosa contraction, poor blood.

(6) decrease in sexual intercourse, sexual intercourse frequency causes the intestinal mucosal congestion, increased bleeding.
