Acute necrotizing pancreatitis is a frequent and potentially lethal disease, especially in case of infected pancreatic necrosis (IPN). IPN usually occurs after the first week of evolution. The step up approach is now widely recommended for the management of IPN. In fact, in case of suspicion of IPN, a drainage percutaneous or transgastric is recommended at first, supported by probabilist antibiotherapy. 1/3 of patients won't require any other interventions. For 2/3 of patients, an additional necrosectomy is necessary. Necrosectomy was formally realized by open laparotomy. Since de last decade, mini-invasive technics have emerged: transgastric necrosectomy, video-assist retroperitoneal debridement. laparoscopy and permitted a decreased of morbidity and mortality. Recently, Hollemans et al. developed a nomogram based on 4 variables (sex, multi-organ failure, % of necrosis and collections heterogeneity) which are negative predictors for success of catheter drainage in IPN with an receiver operating characteristic (ROC) curve at 0.76. The aim of this study is to validate on a large retrospective cohort Hollemans nomogram in predicting catheter drainage success. Secondary aims are to evaluate possible others predictors for success of catheter drainage in IPN and to evaluate the impact of antibiotherapy on microbiological results and on the need for an additional necrosectomy regarding its type and duration, as well as the emergence of multiresistance organism.
Condition or disease
Acute Necrotizing Pancreatitis
Other: Non interventional study
Using electronic patient data monitoring systems, the investigators reviewed all patients with a diagnosis of acute necrotizing pancreatitis admitted to digestive liver disease unity or ICUs at the Nantes University Hospital, Rennes, Angers and Brest University Hospital from January 1, 2012, to december 31, 2017. For enrolled patients, general clinical characteristics were collected. Patients were categorized into two groups according to success of catheter drainage or failure of catheter drainage, and the differences of these characteristics between two groups were evaluated. The Hollemans nomogram is evaluate and potential risk factors will be collected and studied by using multiple logistic regression analysis.
ROC curve of Hollemans nomogram [ Time Frame: up to 4 months ]
Nomogram based on 4 variables independently associated with success of catheter drainage: Male sex, multiple organ failure, increasing percentage of pancreatic necrosis and heterogeneity of the collection . Points are awarded to a factor if it is associated with a reduced success chance of catheter drainage. Favorable scores for all factors (ie, 0 points), result in a 91% success chance of primary catheter drainage. Similarly, unfavorable scores (maximum of 40 points) result in a 2% success chance of primary catheter drainage.
Secondary Outcome Measures :
Potential Predictors of catheter drainage failure [ Time Frame: up to 4 months ]
Potential risk factors included patient demographics, disease severity, complications, morphology on CT, and details of the drainage procedure. Univariate analyses examined potential risk factors on outcome (catheter drainage failure). Then, using multiple logistic regression analysis, factors achieving P≤0.1 in univariate analyses were entered into the model predicting the risk of catheter drainage failure
