Infected pancreatic necrosis (IPN) continues to be a challenging problem for the surgeon. We reviewed the experience on a hepatobiliary surgical service with patients who required operative intervention for IPN with emphasis on surgical approach, timing of surgery, and complications. Between 2002 and 2008, 21 patients underwent surgery for IPN. The initial surgical approach in these 21 patients included either direct pancreatic debridement (DPD, n = 13) or transgastric debridement using cyst-gastrostomy (CG, n = 8). Fifteen patients (71%) required only a single procedure, whereas three (14%) required two procedures and three (14%) required three procedures. The mean time from onset of pancreatitis to operation was 77 days. Patients requiring a single intervention had a longer interval from onset of pancreatitis to surgery compared with those requiring multiple interventions. When comparing CG and DPD groups, there was a longer interval from onset of pancreatitis to debridement, a lower chance of needing multiple debridements, and fewer pancreatic fistulae in the CG group. Overall survival was 95 per cent. Our results demonstrate that CG can be successfully used in select patients with IPN. Patients undergoing CG are less likely to require repeat surgical debridement and to develop pancreatic fistulae compared with patients undergoing DPD.
