Overview

Nasogastric lavage and UpperGI endoscopy are other diagnostic studies that are helpful in the diagnosis of upper gastrointestinal bleeding. Evidence of old (brown colored or 'coffee grounds') or fresh blood documents on nasogastric lavage indicates the presence of UGIB.

Other Diagnostic Studies

Nasogastric lavage

  • Nasogastric lavage is only indicated when the diagnosis of UGIB doubtful.[1][2]
  • It is rarely used.
  • Nasogastric lavage also helps in documenting active or recent UGIB and the need for urgent endoscopy.
  • Occasionally used to empty gastric contents in preparation for endoscopy.

Interpretation

  • Evidence of old (brown colored or 'coffee grounds') or fresh blood documents presence of UGIB.
  • Evidence of bilious material rules out bleeding distal to the pylorus.
  • Any other appearances of GI contents are non-diagnostic.
  • There is no evidence that performing a nasogastric lavage to clear clots or otherwise manage bleeding improves clinical outcome.
  • Determining whether blood is in gastric contents, either vomited or aspirated specimens, is surprisingly difficult.
  • Slide tests are based on orthotolidine (Hematest reagent tablets and Bili-Labstix) or guaiac (Hemoccult and Gastroccult).
  • Rosenthal found orthotolidine-based tests more sensitive than specific; the Hemoccult test's sensitivity reduced by the acidic environment; and the Gastroccult test be the most accurate[3]. Cuellar found the following results:
Determining whether blood is in the gastric aspirate[4]
Finding Sensitivity Specificity Positive predictive value
(prevalence of 39%)		 Negative predictive value
(prevalence of 39%)
Gastroccult 95% 82% 77% 96%
Physician assessment 79% 55% 53% 20%
  • Holman used simulated gastric specimens and found the Hemoccult test to have significant problems with non-specificy and false-positive results, whereas the Gastroccult test was very accurate[5].

Contraindications

  • Avoid gastric lavage in patients with suspected perforated abdominal viscus.

Complicatiions

Complications of the procedure include:

  • Bleeding from trauma during tube passage in patients with coagulopathy is a possible complication.
  • Other rare complications include
    • Pharyngeal and esophageal perforation
    • Cardiac arrest
    • Ethmoid sinus fracture with brain trauma
    • Bronchial intubation.

Upper GI Endoscopy

  • Upper GI Endoscopy is considered investigation of choice for diagnosing and assessing the source of UGIB.[3][4][5]
  • The American Society of Gastrointestinal Endoscopy guidelines recommend that upper gastrointestinal endoscopy be performed within 24 hours of presentation in all patients with UGIB

Indications

  • Active UGIB
  • Used for biopsy lesions for tissue diagnosis and to treat currently bleeding lesions.

Complications

Complications include

  • Aspiration
  • Esophageal perforation
  • Cardiopulmonary complications secondary to anesthesia
  • Increased bleeding while attempting therapeutic intervention
