We found that of 15 adults randomized to antibiotics, 14 achieved stability in the emergency department and were discharged home. All antibiotics-treated participants had their symptoms of acute appendicitis resolve. Like previous trials, we found antibiotics-treated participants recovered much sooner than those treated surgically. Remarkably, about one-third were pain-free and could return to their normal activities after only one day. Many patients would like to avoid surgery, and of course, eliminating hospitalization would also substantially reduce costs.

Over the next year, two antibiotics-treated participants developed recurrent appendicitis; one had surgery, and the other elected to take another antibiotics course and has remained well. So in this small pilot, our one-year appendectomy rate for antibiotics-treated patients was less than 10 percent.
Is ED management and discharge of acute appendicitis ready for prime time? No. However, emergency physicians should be familiar with antibiotics management since some surgeons are early adopters. Also, the topic of antibiotics treatment of appendicitis has been exposed in the lay press; some patients are now inquiring and even demanding this treatment.3
Before antibiotics treatment is mainstreamed, we need to know much more. Comparing against modern endoscopic appendectomy, it must be clearly established that antibiotics lead to no more complications. We need to better understand how patients value permanently curing the disease compared to minimizing that disease’s impact on their life. We also don’t know how much time to give antibiotics to work. One reason we think we saw no initial antibiotics failures in our pilot study was that, with ED discharge, there was less opportunity for surgeons to observe variation in pain control and offer patients appendectomy. We don’t yet know conclusively in which patients antibiotics are more likely to work.
We are now conducting the first multicenter, randomized US trial called Comparing Outcomes of Drugs and Appendectomy (CODA, ClinicalTrials.gov: NCT02800785). Our methods are similar to our pilot study. This work is being done under a Patient-Centered Outcomes Research Institute grant and in collaboration with the University of Washington Department of Surgery in Seattle.
The results of this study will be important in determining if acute appendicitis should be routinely managed from the emergency department like acute diverticulitis. It appears that we are on the verge of a new type of shared decision making with our ED patients, turning the previous understanding about the most common “surgical emergency” on its head.
