Crohn's Disease with Intra-Abdominal Abscess Greater Than 2 cm

When Crohn's disease is complicated by an intra-abdominal abscess larger than 2 cm, a specific and carefully sequenced management approach is required — one that prioritises source control before other therapies can safely continue.

Clinical Scenario

Crohn's disease presenting with a confirmed intra-abdominal abscess greater than 2 cm — a complication requiring prompt intervention focused on achieving drainage, with specific implications for how immunosuppressive treatment is managed.

Treatment Approach

Management involves antibiotic therapy alongside a drainage procedure — carried out radiographically or surgically — with immunosuppression held until drainage has been confirmed. What happens after drainage is achieved, and the role of surgical planning in the subsequent course, is detailed in the full protocol.

Primary Clinical Goal

Achievement of abscess drainage.

We suggest that an intra-abdominal abscess (>2 cm) be treated with antibiotics and a drainage procedure, and immunosuppression held until drainage is achieved, either radiographically or surgically (conditional recommendation, low level of evidence).
Patients with CD who develop an abdominal abscess should undergo a surgical resection. However, some may respond to medical therapy after radiologically guided drainage.
As such, once the abscess has been drained, most patients benefit from a delayed surgical resection.
