ABSTRACT
Objective To study the trends in surgical treatment and the outcomes of critical acute pancreatitis (CAP).Methods The clinical data of 76 patients with CAP who were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University from January 2010 to December 2017 were retrospectively reviewed.Data which included demographics,micro-organisms,surgical interventions and mortality were compared between the time periods of 2010 to 2013 and 2014 to 2017.Results Before 2014,19 patients with CAP were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University.The percentage of multidrug resistant organisms (MDRO) in pancreatic drainage was 5.3％ (1/19).In the latter 4 years,57 patients with CAP were treated.The percentage of MDRO was 50.9％ (29/57),which was significandy higher than the initial 4 years (P＜0.001).For surgical treatment,the proportion of minimally invasive surgery in the latter 4 years was significantly higher than that in the initial 4 years.The percentage of percutaneous catheter drainage (PCD) increased from 63.2％ in the initial 4 years to 86.0％ in the latter 4 years.The proportion of minimal access retroperitoneal pancreatic necrosectomy (MARPN) increased from zero in the initial 4 years to 59.6％,while the proportion of open pancreatic necrosectomy (OPN) decreased from 68.4％ in the initial 4 years to 24.6％.The mortality rate of patients with CAP dropped from 52.6％ (10/19) in the initial 4 years to 24.6％ (14/57) in the latter four years.Conclusions In the center which specializes in treating pancreatitis,although the problem of bacterial resistance had become increasingly prominent,the mortality rate of CAP had shown a significant downward trend due to the development of various minimally invasive techniques.
