Not all presentations of acute appendicitis are the same. In certain complicated cases — where significant cecal inflammation, a longer symptom course, or a discrete periappendicular abscess is present — the initial management strategy differs from straightforward appendicitis, and the risk-benefit calculation for immediate surgery shifts substantially.
This protocol applies to patients with complicated appendicitis who have one or more of the following: significant cecal inflammation, a symptom duration exceeding one week or otherwise delayed presentation, or a well-formed (discrete) abscess in the periappendicular region. These findings are associated with higher operative risks and warrant a tailored initial approach.
The initial strategy centres on nonoperative management, which includes intravenous antibiotics. For patients presenting with a well-formed abscess, an additional intervention may also be considered as part of the initial approach. The full protocol — including selection criteria, sequencing, and follow-up pathway — is accessible via the link below.

In patients with significant cecal inflammation, longer symptom duration/delayed presentation, or a well-formed abscess, the panel notes that greater consideration can be given to initial nonoperative management in an effort to minimize surgical risks.
In addition, patients with a discrete abscess, significant cecal inflammation, or symptoms for longer than a week may benefit from initial nonoperative management given the higher operative risks in these patient populations.
Percutaneous drainage is also an option for patients that present with a well-formed abscess.
