Infected Pancreatic Necrosis Not Responding to Antibiotics
Clinical Scenario
Infected pancreatic necrosis is a serious complication of acute pancreatitis in which necrotic tissue becomes bacterially colonised. Antibiotics are an important part of treatment in infected necrosis alongside debridement, but antibiotic therapy alone does not always achieve complete resolution of the infection.
Previous Line — Goal Not Achieved
Antibiotics known to penetrate pancreatic necrosis — including carbapenems, quinolones, cephalosporins, and metronidazole — were used. The target was complete resolution of the infection, potentially allowing some patients to avoid drainage altogether. When there is no adequate response within a short time, or when the clinical situation deteriorates, escalation to the next step is required.
Next-Step Approach (Partial Overview)
Management moves to interventional removal of necrotic tissue. Minimally invasive techniques are generally favoured over open surgery in clinically stable patients — but the full structured protocol, including the specific sequence of interventions and patient selection criteria, is available via the link below.

- While antibiotics should not be used in patients with sterile necrosis, antibiotics are an important part of treatment in infected necrosis along with debridement/necrosectomy.
- If there is no response to such antibiotics in a short time or if the clinical situation deteriorates, necrosectomy/debridement should be performed.
- Minimally invasive methods are preferred to open surgery for debridement and necrosectomy in stable patients with symptomatic pancreatic necrosis.
- A well-designed study from the Netherlands using a step-up approach (percutaneous catheter drainage followed by video-assisted retroperitoneal debridement) demonstrated the superiority of the step-up approach by way of lower morbidity (less multiple organ failure and surgical complications) and lower costs.
