   Definition

   Types

   Causes

   Management

  Bleeding distal to the ligament of
treitz(4th part of duodenum) to anus
 Common but most patients do not require
  hospital admission.
 Bleeding stop spontaneously in 90% of
  patient before transfusion requirements
  exceed 2 unite.
 Men more than woman.
 The rate of bleeding increases 200-fold from
  the third to ninth decades of life .
 If passing bright red blood but not in shock
  bleeding probably from small intestine or
 May be:
     Acute _massive rectal bleeding.
     Chronic.
massive rectal bleeding
 Passage of large volume of red or maroon
  blood through the rectum.
 Hemodynamic instability and shock.
 initial decrease in hematocrit level of 6 g/dl or
 Transfusion of at least 2 units of packed red
  blood cells.
 bleeding that continues for 3days.
 significant rebleeding in 1week.
Causes of Lower GI Bleeding
 Divericular disease , most common cause.
 Angiodysplasia.
 Colon cancer &other neoplasms.
 Inflammatory bowel disease.
 Anorectal (hemorrhoids & fissure).
 Upper GI source.
 Polyps.
 AIDS-related lesions.
 Meckel’s diverticulum.
 Arteriovenous malformation.
 Aortoenteric fistula.
 Bowel ischemia.
 Postendoscopic bleeding.
 Is asaccular out pouching of mucosa through the
  colonic musculature.

 It can be acquired or congenital.
Acquired divericluta

 Most common type.
 Contain only the mucosa and submucosal
 May occur throughout GI tract BUT are most
  common in large bowel, with 95% patients
  having divertcular in Sigmoid colon.
Congenital divertcula
 Contain all layer of bowel wall.
 Predominantly located in the right colon in or
  near the cecum.
 Most common type is Meckel’s diverticulum .

 Male = female.
 Age - <5% at 40 years of age ,
   65%in those >85 years old.
 Region- higher in western nations.
Clinical presentation
 80% are Asymptomatic.
 Number of patient present with one or more
  complication like :
     Painful diverticulosis .
     Acute diverticulitis.
     Perforation of diverticulm.
     Obstruction.
 Fistula
 Hemorrhage

   Stop spontaneously in 80% of patients
   If it is massive bleeding , take it as
  life-threatening condition
 Prevention –high fiber diet decrease
  incidence of symptoms like fruits and

 Surgery may be required for complications.
 Is arteriovenous malformation located in
  cecum and ascending colon.

 Affected elderly persons older than 60 years.

 The lesion are composed of clusters of
  dilated vessels, mostly Veins.
 Unlike diverticular bleeding, must it is slow
  but repeated episodes of bleeding.

 Patients present with anemia and syncopal
  episodes .
Lower GI Bleeding
        Character and quantity of the blood
        Hx of HTN, CAD, or PVD (ischemic
        Hx of peptic ulcer, liver disease,
      cirrhosis,IBD or coagulopathy.
        Drug Hx like NSAIDs or anticoagulants.
Lower GI Bleeding
Physical Examination:
   look for shock signs (low BP, weak rapid pulse,
    tachycardia, tachypnea , sweating , pallor, cold
     extremities, …etc)
    signs of liver disease (spider nevi, gynecomastia,
     splenomegaly, ascites, …etc)
   look for abdominal masses.
   listen for bruits.
   PR examination (masses , hemorrhoids, fissures)
Lower GI Bleeding
    CBC (but Hb/Hct ,may not reflect true blood volume in patient with acute
    blood loss)
 U&E
 Radiological studies :
     > CT may show thicking of bowel in cas of mesentric ischemia
     > Diverticulosis usually easily identified
Lower GI Bleeding
Diverticulosis .
Lower GI Bleeding
Rule out upper GI bleeding source:
 up to 12% of patients who are thought to have
  a LGIB are actually bleeding from the UGI tract.
 patient may need UGI endoscopy for
Lower GI Bleeding
 often first maneuver.
 visualization difficulty is usually secondary to
  poor preparation.
Lower GI Bleeding
Tagged RBC scan (nuclear medicine):
 99mTc-pertechnaetate-labeled RBCs,
 demonstrate bleeding source when the rate
  of the bleeding is 0.1- 0.5ml/minute.
 allows repeated evaluation over course of 24
 may not exactly localize source and may not
  be able to differentiate colon from small
     typically not used alone for localization.
Lower GI Bleeding
 better for specific localization.
 sensitive for bleeding rate 0.5 - 1.5
 often require large amount of contras
 (beware of renal insufficiency )
 can be therapeutic (emoblization,
Lower GI Bleeding
Capsule Endoscopy:
 may be effective if
 the above methods
 may be the only
 way to identify small
 bowel source.
         Treatment of
        Lower GI Bleeding

Most patients are elderly and the bleeding
         usually is not severe and
     frequently stops spontaneously.
Massive Bleeding with Hypovolaemia

Initial resuscitation is needed which include :

secure airway, breathing and circulation.
insert two large bore i.v. cannulae .
insert urinary catheter.
 send bloods for group and cross-match ,full blood
count ,urea and electrolytes , cereatinine

give i.v. fluids: crystalloids to be begin and then
blood if necessary .

monitor pulse, BP ( CVP if the pt is shocked ) ,
pulse oximetry , urinary output .
Assess severity

a- mild : no hypovolaemia

b – moderate : hypovolaemia that responds to
volume replacement , pt remains stable

c- severe : active continued major bleeding
requiring continuous resuscitation or recurrent
bleed .
investigation proceeds with resuscitation

 a- proctoscopy : exclude hemorrhoids.

 b – colonoscopy : often difficult to see anything
 because of blood.

 c - upper gastrointestinal endoscopy : bleeding
  may be from a duodenal ulcer.

 d - mesenteric angiography.

 e - radiolabelled red cell scanning.
Indications for surgery : continued

remove segment of bowel containing ' bleeder ' if
     known from preoperative investigation
if source unknown , perform laparotomy with
intraoperative colonoscopy to try and identify '
bleeder' if source still cannot be found , a total
colectomy may be needed.
