Washington Post: Antibiotics may help people avoid surgery for appendicitis
By Laura Dattaro
Though appendectomies have been the gold standard of care since before the turn of the 20th century, doctors have been treating appendicitis with antibiotics since the 1950s, as soon as they became available — a “dark secret” in the surgery world, says David R. Flum, professor of surgery and director of the Surgical Outcomes Research Center at the University of Washington. A 1959 paper detailed the use of antibiotics to treat nearly 500 people (a mix of adults and children) with appendicitis. They were — and still are — often used in people whose appendicitis is so advanced that surgery risks spreading the infection further. The military relied on antibiotics for service members who got appendicitis while in inaccessible locations, like submarines.
But the treatment didn’t get wider attention until the late 1990s and early 2000s, Flum says, when researchers began to collect data on how often antibiotics don’t work and found that failure was not as common as they thought.
Then came two large, randomized trials in adults. In the first, published in 2015, 257 adults received an antibiotic treatment. Seventy of those patients, or 27 percent, had to have an appendectomy within one year. But the rest were fine.
A second, larger study of 1,552 adults had similar results: Twenty-nine percent of the 776 people who received antibiotics underwent surgery within 90 days; 4 percent of people in the antibiotics group had serious adverse events, compared with 3 percent in the appendectomy group. The New England Journal of Medicine published the results in 2020. The same year, the American College of Surgeons added nonoperative management as an option in its guidelines for treating appendicitis.
