Prompt appendectomy is commonly recommended for uncomplicated appendicitis. Randomized trials comparing appendectomy through an antibiotics-first strategy have shown similar complication rates but substantial crossover to or later distress for appendectomy with the latter generalship.  A new Clinical Practice notice critically article covers this topic.

A greater uncertainty in the management of appendicitis is whether one appendectomy is needed or whether antibiotics alone, by an appendectomy performed only if the appendicitis does not resolve (each “antibiotics first” strategy), is a sober alternative. Success with an antibiotics-alone come nearly up in Navy personnel who developed appendicitis as long as at sea (without access to one operating room) supported this strategy. Subsequently, diverse [European] randomized trials compared appendectomy by an antibiotics-first strategy (with appendectomy to the degree that needed) for uncomplicated appendicitis.

Clinical Pearls

– What is the protocol on account of an antibiotics-first approach, and to what degree do the clinical outcomes compare to those of appendectomy?

The European randomized trials involved a pass near of interventions and durations of management. A typical protocol included 48 hours of intravenous antibiotics during the time that the patient was in the hospital, followed ~ dint of. 7 days of oral antibiotics that are easily affected to the typical organisms found in intraabdominal bane (e.g., ciprofloxacin and metronidazole), and did not embody repeat imaging to confirm resolution of appendicitis. Clinical outcomes among patients randomly assigned to the antibiotics-principal strategy were generally favorable, but the metrics of issue were inconsistent (including reduction in spotless-cell count, avoidance of peritonitis, and usual symptom reduction; several trials had actual small samples). As compared with patients assigned to experience prompt appendectomy, patients assigned to the antibiotics-~ and foremost strategy had lower or similar punishment scores, required fewer doses of narcotics, and had a quicker return to work, but these outcomes were not assessed in the studies. Perforation rates were not significantly higher amidst patients assigned to the antibiotics-chief approach. The rate of crossover to surgery inside of 48 hours after the initiation of antibiotics ranged in the midst of trials from 0 to 53%. Because the studies used various criteria to trigger a crossover, this variability suggests subsistent heterogeneity of treatment effect across patients or modification in clinicians’ willingness to adhere to the antibiotic come near.

– What is the impost of recurrent appendicitis when initial antibiotic management has been successful?

In the European trials, possible appendectomy after initial, successful treatment with antibiotics occurred in 10 to 37% of the patients randomly assigned to the antibiotics-in the ~ place strategy (mean time to appendectomy, 4.2 to 7 months in the three studies in which this outcome was reported). Data from longer follow-up periods were unavailable, and accordingly it is unclear whether the likelihood of appendectomy continued to increase or stabilized to boot time. In one report that included information on subsequent surgical pathological results, 13% of the patients who underwent later appendectomy (~wards initially successful treatment with an antibiotics-rudimentary strategy) did not actually have appendicitis; in this wise, the true rate of recurrent appendicitis is renownless.

Morning Report Questions

Q: What questions wait unanswered about the use of the antibiotics-primary approach?

A: All these studies were performed in Europe, and the thing done that surgical patients more often underwent “open” appendectomy (34 to 82%), through an associated longer duration of hospital stay hind surgery (mean, approximately 3 days) than is representative in the United States, limits extrapolation of the results to the United States. Questions endure about whether complications related to delayed surgery, the consist of of days of antibiotic therapy, the footing of time spent in health care, trouble about future episodes of abdominal hurt, and total costs of care bicker substantively between treatment options. Furthermore, factors associated through a higher risk of recurrence are unclear, and it is not publicly possible to identify patients who should have existence directed to surgery or offered one antibiotics-first strategy.

Q: Do professional association guidelines support an antibiotics-first tactics for acute uncomplicated appendicitis?

A: The American College of Surgeons, the Society instead of Surgery of the Alimentary Tract, and the World Society of Emergency Surgery aggregate describe appendectomy (either laparoscopic or free) as the treatment of choice in favor of appendicitis. Regarding an antibiotics-first generalship, the American College of Surgeons able to endure information guide indicates that it “may exist effective, but there is a higher hazard of reoccurrence”; the Society for Surgery of the Alimentary Tract assiduous care guidelines suggest that it is “not a widely accepted treatment”; and the World Society of Emergency Surgery states that “this opposed to change approach features high rates of resort and is therefore inferior to the traditional appendectomy . . . Non-operative antibiotic treatment may have existence used as an alternative treatment since specific patients for whom surgery is contraindicated.”
