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

Study Arms (2)
Control
NO INTERVENTIONPatient gets usual diagnostic path: after inconclusive ultrasound is refered to CT scan.
Observation
ACTIVE COMPARATORPatient 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.
Interventions
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.
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.
- No other gynecological, urological ir gastroenterological pathology is confirmed.
- Clinical symptoms lasts for longer than 48 hours
- Signs of peritonitis
