What is the preferred treatment for stable patients with likely perforated appendicitis?

In cases of likely perforated appendicitis in stable patients, the preferred treatment is the administration of intravenous antibiotics combined with percutaneous drainage. This management approach is particularly suitable for patients who are stable and may present with a localized abscess or a contained perforation.

Using intravenous antibiotics helps to manage the infection effectively while percutaneous drainage allows for the removal of any abscess that may have formed, thereby reducing the risk of widespread infection or sepsis. This treatment strategy provides a means to stabilize the patient's condition without the immediate need for invasive surgical intervention, which can carry higher risks, especially when considering the patient's stability.

In contrast, immediate surgical intervention may be excessively aggressive for stable patients and can lead to complications. Observation without treatment can lead to the progression of the condition and may increase the risk of serious complications, such as generalized peritonitis. Administering oral antibiotics and discharging the patient would not be adequate for managing a likely perforated appendicitis, as it does not address the potential need for surgical intervention or drainage of any abscess.
