Introduction: Approximately 5% of patients with acute pancreatitis develop infected necrotizing pancreatitis, with reported mortality rates up to 32%. Surgical interventions are postponed as long as possible, but if surgical debridement is needed the optimal approach has not been found yet. Case presentation: A 47-year-old male was referred to our tertiary centre with infected necrotizing pancreatitis. Two months after initial presentation and repeated percutaneous drainage, surgical retroperitoneal debridement of the necrotic tissue was performed using a single incision laparoscopic surgery (SILS) port. Postoperatively, percutaneous drainage was performed two more times, but no additional surgical interventions were needed. The patient was discharged one month after the surgical procedure. Discussion and conclusion: This is the first report of a minimally invasive technique using a SILS port for debridement of necrotizing pancreatitis. The ability to create a stable pneumo-retroperitoneum leads to optimal visualisation, better haemostasis, more space to operate in, better instrument handling, and better tissue control.
