NCT04117061

Brief Summary

Aim of the study: to identify the signs of acute appendicitis delta signs - clinical, laboratory or ultrasound signs, whose change (delta) would allow to identify or deny the diagnosis of acute appendicitis without a computed tomography examination and thus to lower computed tomography rates.

Outcome Measures

Primary Outcomes (2)

  • Reduction of the CT scans number

    when performing alternative diagnostic protocol, that includes patient observation for short period we expect to reduce a number of CT scans performed, for the patients with suspected acute appendicitis.

    24 hours

  • Negative appendectomy rate

    We expect the negative appendectomy rate will will not increase while using alternative diagnostic protocol that includes patient observation.

    30 days

Secondary Outcomes (5)

  • Delta marker White blood cell count

    12 hours

  • Delta marker CRP count

    12 hours

  • Delta marker Alvarado acute appendicitis risk evaluation score

    12 hours

  • Delta marker changes in ultrasound results

    12 hours

  • 'Appendicitis Inflammatory Response (AIR) Score'

    12 hours

Study Arms (2)

Control

NO INTERVENTION

Patient gets usual diagnostic path: after inconclusive ultrasound is refered to CT scan.

Observation

ACTIVE COMPARATOR

Patient after inconclusive primary evaluation is observed in emergency room for 8-12 hours and after the clinical evaluation, laboratory results and ultrasound examination is repeated.

Procedure: Observation

Interventions

ObservationPROCEDURE

Patient after primary investigation is observed for 8-12 hours, (instead of being send directly to CT scan), after observation repeated clinical evaluation, laboratory tests and ultrasound examination are done , if final diagnosis stays unclear the patient is refered to CT scan.

Observation

Eligibility Criteria

You may qualify if:

  • Patient with the symptoms of acute appendicitis: pain in the right lower quadrant, pain migration from epigastrium to right lower quadrant, nausea, rebound pain, elevated temperature.

You may not qualify if:

  • Pregnant patient.
  • After primary clinical, laboratory and ultrasound examination diagnosis of acute appendicitis could not be confirmed or excluded.
