Presentation Transcript

  1. Bleeding from the GutClinical approach • Severity Vital signs Haematocrit Beware ongoing losses • Acute onset or chronic blood loss Fe deficiency • Stigmata of disease Failure to thrive and grow Purpura Liver and spleen

  2. Site of bleeding • Haematemesis Fresh blood swallowed, rapid haemorrhage Altered - “coffee ground” gastric acid

  3. Site of bleeding • Bleeding per rectum Fresh blood not mixed with stool low rectum and anus Fresh blood with mucus - dysentery colon and rectum Jellied dark blood intussusception Melaena - tarry black bleeding from higher up

  4. Bleeding from the gut • Bleeding tendency Vitamin K deficiency Hepatic failure Disseminated intravascular coagulation septicaemia, necrotising enterocolitis Thrombocytopaenia haemolytic uraemic syndrome Vasculitis - Henoch Schonlein purpura

  5. Bleeding from the Gut • Swallowed blood Maternal blood swallowed intrapartum Apt test Nose bleed Mouth and pharynx • Oesophagus Varices (portal hypertension) Oesophagitis (peptic or other) Mallory-Weiss tear

  6. Bleeding from the Gut • Stomach Gastritis and erosions Ulcer (peptic, stress) • Small gut Meckel diverticulum Ulcers (peptic and inflammatory) Intussusception Volvulus Polyps

  7. Bleeding from the Gut • Large gut Dysentery (amoebic, bacterial) Intussusception Polyps Ulcerative colitis • Rectum and anus Varices Polyps Trauma Anal fissure

  8. Bleeding from the gutManagement • Resuscitation as required • Stop the bleeding mostly spontaneous vitamin K blood component therapy emergency endoscopic approach

  9. Bleeding from the GutManagement • Identify the site of haemorrhage History Character of blood Upper gut: endoscopy Lower gut: contrast studies isotope scan “Meckel scan” endoscopy • Identify and manage aetiology • Follow-up for recurrence

  10. Dysentery • Mucosal invasion or toxin mediated inflammation with necrosis bacteria - shigella, Esch.coli, others Entamoeba histolytica, trichiuris • Fever, abdominal pain, extraintestinal features • Sometimes onset in “gastro-like” fashion • Major complications
