Diagnosis and preparation
The diagnosis of acute appendicitis is based on a careful examination of the abdomen, supplemented by specific laboratory tests and an ultrasound examination. This combination enables a precise assessment of the condition and helps to rule out other possible causes of abdominal pain as far as possible.
As appendicitis usually occurs acutely, it is often an emergency operation that cannot be planned in advance. In such cases, a rapid response is crucial in order to prevent serious complications with a longer hospital stay.
The appendectomy is performed under general anesthesia.
Appendectomy procedure
At the USZ, the minimally invasive technique, also known as the “keyhole technique”, is primarily used. In this procedure, the operation is performed through three small incisions in the abdominal area, each only 0.5 to 1.5 cm long. The appendix is carefully separated from the end of the colon using a special staple cutter.
In the case of a burst appendix or particularly severe inflammation, more extensive surgery may be necessary. Whenever possible, extended laparoscopic surgery is performed. Open surgery with an incision between the navel and pubic bone is only performed if absolutely necessary.
Aftercare for appendicitis
After an uncomplicated appendectomy, the hospital stay is usually around two days. A full recovery with the ability to work is usually possible after around two weeks. If the appendix has already burst during the operation, the hospital stay can be considerably longer. The complication rates with intestinal passage disorders and abscesses in the abdominal cavity are also significantly higher and can delay healing accordingly. Patients with ruptured or perforated appendicitis usually receive several days of antibiotic therapy and, depending on the problems that arise, additional interventions.
