Type surgical site infection (SSI) | Description |
|---|---|
Superficial incisional SSI | Wound infection defined according to the CDC definition [17] |

Isolated OSI | Isolated (non-pancreatic fistula) OSI: absence of concurrent anastomotic leak (pancreatojejunostomy, defined as postoperative pancreatic fistula (POPF), hepaticojejunostomy or gastrojejunostomy) |
Non-isolated OSI | Not-isolated OSI: concurrent anastomotic leak (at time of OSI diagnosis) |
Clinically relevant OSI (primary outcome) | An isolated or non-isolated OSI is clinically relevant in case of: - Requirement of a radiological, endoscopic or surgical intervention, or therapeutic antibiotics for an episode of sepsis (defined as two or more SIRS criteria) and - Organisms isolated from an aseptically obtained culture |
