Brief Summary:
To compare surgical site infection (SSI) rate in patients undergoing laparoscopic appendectomy for acute uncomplicated appendicitis and treated with single dose regime of antibiotics versus group of patients undergoing laparoscopic appendectomy without antibiotics treatment. Patient will be given either single dose of perioperative antibiotics or no antibiotics before surgery.

Condition or disease Intervention/treatment Phase
Appendicitis Drug: cefamezin 1g IV Drug: metronidazole 500 mg IV Drug: Placebo Not Applicable

Detailed Description:

Laparoscopic appendectomies are performed by one of the 6 institutional attending surgeons. US and/or abdominal CT scans are obtained as clinically necessary to make the diagnosis of appendicitis. All of the appendectomies are initiated laparoscopically. Postoperative orders are controlled via a standard electronic order set for all operations.

Patients found to have acute uncomplicated appendicitis at appendectomy will be randomized to either single dose of perioperative antibiotics /On the second post-operative day the patient who has no fever and tolerating a regular diet, will be discharged home without oral antibiotics. On the post-operative, day seven after surgery all patients will be examined in the outpatient clinic on the presence of surgical site infection. then will be followed for a 30 days after surgery .

Primary Outcome Measures :
  1. The main target-point of the study is surgical site infection (SSI), defined according to the Centers for Disease Control (CDC). [ Time Frame: 30 Days ]

    Criteria for a superficial incisional SSI are an infection occurring at the incision site within 30 days after surgery that involved only the skin and subcutaneous tissue and at least one of the following:

    purulent drainage from the incision; an organism isolated from a culture of fluid from the superficial incision; incisional pain, tenderness, localized swelling, redness, or heat, and the wound was opened;
