Investigations in lower gastrointestinal bleed Investigations in lower gastrointestinal bleed Presentation Transcript

  • LOWER GI BLEED
  • ROUTINE INVESTIGATIONS BLOOD ROUTINE -Hb -PCV -ESR• URINE ROUTINE STOOL EXAMINATION
  • SPECIAL INVESTIGATIONS SIGMOIDOSCOPY COLONOSCOPY VIDEO CAPSULE ENTEROSCOPY Tc-RBC SCAN ANGIOGRAPHY
  • SIGMOIDOSCOPY & COLONOSCOPY  60 cm flexible colonoscope following bowel preparation  Combined with proctoscopy: -detectn of haemorrhoids,ulcerative col. - colorectal neoplasms -angiodysplasia,bowel ischaemia
  • FLEXIBLESIGMOIDOSCOPE
  • C/I -s/v active ulcerative colitis -s/v shockCOMPLICATIONS -perforation -bleeding following polypectomy
  • VIDEO CAPSULE ENDOSCOPY employs a 26mm capsule with an imaging device, battery, transmitter & antennae. Transmits images as it traverses to a battery powered recorder worn on a belt around the waist. Capsule excreted after 8hrs Images analysed as video sequence & lesions localised.
  • VIDEO CAPSULE
  • C/I -known or suspected bowel stricture -caution in pts with pacemakerCOMPLICATIONS -capsule retention
  • DOUBLE BALLOON ENDOSCOPY
  • Long endoscope with a flexible tubeSequential,repeated inflation & deflation of balloon pushes & pulls the endoscope along the entire length of SI to the terminal ileum.Diagnose & treat small bowel lesions.
  • C/I -perforation -shockCOMPLICATIONS -post procedure abdominal pain -pancreatitis
  • ANGIOGRAPHY
  • Tc PERTECHNATE SCANDiagnosis of MECKEL’S DIVERTICULUM in obscure GI bleeding.Isotope injected i.v. and localises in ectopic parietal mucosa with diverticulum.
