The conventional surgical approach includes debridement, intraoperative lavage, and Penrose/sump drainage. Reoperations, usually for persistent intra-abdominal infection, are necessary in more than a third of these patients. As a consequence of technical improvements (e.g. more aggressive debridement, wider drainage, and insertion of multiple sump and rubber drains), a decrease in hospital mortality of necrotizing pancreatitis or pancreatic abscess to 24 per cent could be achieved. If this form of drainage is chosen, a low threshold for re-explorations is imperative.
