Inclusion Criteria

Diagnosed acute appendicitis, in which laparoscopic appendectomy is planned. Diagnosis should be confirmed either by high Adult Appendicitis Score (16 or over) or by diagnostic imaging including computed tomography (CT), ultrasound or magnetic resonance imaging (MRI). All patients with symptoms over three days should undergo CT or MRI before inclusion.

F.1.3.1 Number of subjects for this age range 200

Exclusion Criteria

1. Complicated appendicitis based on imaging studies. These include following findings:
a. extraluminal air or extraluminal fecalith
b. fluid collection, abscess or phlegmon around appendix
c. nonenhancing appendices wall on contrast enhanced imaging
2. Likely complicated appendix based on laparatory testing defined by plasma C-reactive protein (P-CRP) 100 mg/l or over.
3. Fever measured on emergency department over 38.5 degrees Celsius
4. Clinical diffuse peritonitis or other reason , which may indicate immediate surgery.
5. Pregnancy

Primary Outcome Measures
NameTimeMethod
Main Objective: To find effect of preoperative delay and preoperative antibiotic treatment on rate of complicated appendicitis. Complicated appendicitis is defined by AAST Grade III-V.;Secondary Objective: Effect of preoperative antibiotics and delay on hospitalization, complications, pain during waiting surgery, surgical site infections and positive blood cultures, conversion during laparoscopic appendectomy, histopathological grade of appendicitis, degree of purulent fluid on abdomen (SAGS-classification);Primary end point(s): Number of patients with complicated appendicitis at surgery. Complicated appendicitis is defined by AAST Grade III-V.;Timepoint(s) of evaluation of this end point: During the appendectomy.
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): 1. Hospitalization time in hours from randomization.<br>2. Complications within 30 days from operation, classified according to Clavien-Dindo classification.<br>3. Pain (Numeric Rating Scale) while waiting surgery<br>4. Surgical site infections ja positive blood cultures within 30 days from randomization.<br>5. Conversions of laparoscopic surgery to open<br>6. Gangrene of perforation in histological examination of appendix<br>7. Sunshine appendicitis grading system score differences;Timepoint(s) of evaluation of this end point: 1. at time of discharge<br>2. 30 days from surgery<br>3. every hour from randomization until to the beginning of the surgery<br>4. 30 days from randomization<br>5. at the end of surgery<br>6. 30 days from surgery<br>7. at the end of surgery
