[Experience of minimal-access video-assisted retroperitoneal debridement in treatment of infected pancreatic necrosis].

Objective: To explore the experience of minimal-access video-assisted retroperitoneal debridement in treatment of infected pancreatic necrosis(IPN). Methods: A retrospective review was performed on 12 patients with IPN who underwent minimal-access video-assisted retroperitoneal debridement between June 2008 and June 2013 in People's Liberation Army General Hospital and First Affiliated Hospital of People's Liberation Army General Hospital, respectively.There were 10 male patients and 2 female patients aging from 33 to 55 years with mean age of(43±8)years.Pancreas infective necrosis, the serious complications of severe acute pancreatitis occurred in all of the patients among which there were 2 patients with infection after percutaneous catheter drainage(PCD)in early phase of disease, and 12 patients with spontaneous during the late phase. The technical strategies of the minimally invasive treatment mainly included PCD, minimal-access video-assisted retroperitoneal debridement, and irrigation. Results: Ten patients received PCD and the median time from onset of acute necrotizing pancreatitis to PCD was mean of 24 days(range 8-86 days). Minimal-access video-assisted retroperitoneal debridement was performed after 18 days(range 3-29 days) after PCD.Three patients died after surgery.Five patients had hemorrhage complication and 3 had colonic fistula.Pancreatic fistula occurred in 2 patients. Conclusions: The technique of minimal-access video-assisted retroperitoneal debridement has advantage and some minor disadvantage.Delayed minimal-access video-assisted retroperitoneal debridement is recommended.
