Appendicitis is almost always treated with surgery to remove the appendix, and it remains one of the most commonly performed emergency operations worldwide. In select cases of uncomplicated appendicitis, antibiotics alone can resolve the infection without an operation, though about 18% of people treated this way will have appendicitis come back. The right approach depends on whether the appendix has ruptured, how severe the inflammation is, and the patient’s age and overall health.
Surgery: The Standard Treatment
Removing the appendix, called an appendectomy, is the most reliable way to treat appendicitis. There are two surgical approaches, and both are well established.
Laparoscopic surgery uses three small incisions, each about half an inch, through which a camera and instruments are inserted. This is now the most common technique. Compared to open surgery, patients leave the hospital about a day sooner and return to normal activity roughly five days earlier. The risk of developing a bowel obstruction afterward is also lower: about 1.2% with laparoscopic surgery versus 4.5% with the open approach.
Open surgery involves a single incision of about two inches in the lower right abdomen. Surgeons may choose this route when the appendix has ruptured, when there’s a large abscess, or when extensive inflammation makes laparoscopic access difficult. It’s also sometimes necessary if a laparoscopic procedure needs to be converted partway through due to unexpected findings.
Antibiotics Without Surgery
For uncomplicated appendicitis, where the appendix hasn’t ruptured and there’s no abscess, antibiotics alone are an option some patients and surgeons now consider. Treatment typically starts with intravenous antibiotics in the hospital, followed by oral antibiotics at home. The success rate is meaningful but consistently lower than surgery, roughly 18% less effective by some analyses. Complications tend to be less frequent with antibiotic treatment, but the tradeoff is the risk of recurrence: overall, about 18.2% of adults treated with antibiotics will eventually need their appendix removed anyway.
This approach works best for people who want to avoid surgery or who have medical conditions that make anesthesia risky. It requires close monitoring, and you need to be prepared for the possibility that the appendicitis returns weeks or months later.
When the Appendix Has Ruptured
A ruptured, or perforated, appendix changes the treatment plan significantly. Surgery is still generally recommended, but the timing and approach depend on what’s happening inside the abdomen.
If you arrive at the hospital early after a rupture, surgeons will typically operate promptly. But if you’ve had symptoms for several days, or if a walled-off abscess has already formed, immediate surgery carries higher risks because the surrounding tissue is severely inflamed. In those cases, the initial treatment often involves IV antibiotics and, if there’s a well-formed abscess, a drain placed through the skin using image guidance to remove the infected fluid.
Once the infection settles down, surgeons typically recommend a delayed operation called an interval appendectomy, performed weeks later when conditions are safer. This follow-up surgery matters partly because tissue removed during interval appendectomy reveals unexpected growths, including some that are cancerous, in roughly 14% of cases. That rate climbs higher in patients over 40. After surgery for complicated appendicitis, a short course of antibiotics, usually around four days, is standard.
Treatment in Children
Children with appendicitis are treated along similar lines as adults, but there are some important differences in how the options play out. About 14% of children with uncomplicated appendicitis are now managed with antibiotics alone rather than immediate surgery, based on a large study of over 73,000 pediatric cases.
The results are worth understanding clearly. Among children treated without surgery, about one in five eventually needed an operation. At five years out, the failure rate reached 23.3%. More concerning, nearly half of children whose antibiotic treatment failed were found to have a perforated appendix at the time of that later surgery, a higher perforation rate than in children who had surgery right away. Children who initially tried antibiotics and then needed surgery also had slightly higher complication rates (1.9%) compared to those who had surgery up front (1.2%).
Children managed with antibiotics also had more follow-up emergency department visits, more hospitalizations, and more imaging scans in the months that followed. For families considering the antibiotic route, these numbers help frame the real-world tradeoffs.
What Happens Before Surgery
Once appendicitis is confirmed, preparation for surgery moves quickly. You’ll receive IV fluids to correct any dehydration from vomiting or not eating, along with IV antibiotics to start fighting infection before the operation begins. Pain medication is given as needed, though surgeons avoid certain anti-inflammatory painkillers before the procedure because they can increase bleeding risk.
Most appendectomies are performed within hours of diagnosis. You won’t eat or drink anything beforehand, and the surgical team will review imaging results and blood work to determine whether the case looks uncomplicated or whether they should prepare for a more complex operation.
Recovery After an Appendectomy
Recovery from a laparoscopic appendectomy is relatively fast. Most people go back to work within one to two weeks. Open surgery takes longer, and complicated cases with rupture or abscess add additional healing time.
For about two weeks after surgery, you should avoid lifting anything heavy enough to make you strain. That includes young children, heavy grocery bags, large pet food bags, backpacks, and vacuum cleaners. Strenuous exercise like jogging, cycling, and weight lifting is also off limits during this window.
You can expect some soreness around the incision sites for the first several days. Walking is encouraged early and often, as it helps prevent blood clots and gets your digestive system moving again. Most people can eat normally within a day or two, starting with light foods and progressing as tolerated. If you had a complicated case with a rupture, recovery may involve a longer hospital stay, continued antibiotics at home, and a slower return to full activity.
