Operative Trends for XXXX in the USA: Analysis of the Nationwide Inpatient Sample from 1998-2011.

@entity1 @entity788 @entity5 @entity660 @entity9007
UNASSIGNED: The epidemiology of @entity660 is changing. Our aim was to determine the change in indications, frequency, and type of operations being performed for primary @entity660 in the USA. Using the Nationwide Inpatient Sample, all @entity1 aged >= 18  years who underwent pancreatic operations for a primary pancreatic indication between 1998-2011 were identified. Age- and sex-adjusted rates per million adult population were calculated using the 2010 US population as reference. Changes in @entity1 characteristics and outcomes were analyzed. Of 151,454 operations, 82  % were resections and 64  % were performed for @entity5 (malignant 52  %, benign 12  %). Operative rates/million population increased from 41.36 in 1998 to 62.3 in 2011. Population rates increased significantly for distal pancreatectomy, but decreased significantly for drainage procedures (p   <   0.05). Additionally, operative rates increased significantly for @entity5 and cysts/ @entity9007 , but decreased significantly for acute @entity788 (p   <   0.05). During this period, mean age, and comorbidity burden for @entity1 undergoing pancreatic operations increased significantly, while their length of hospital stay and in-hospital mortality decreased significantly (p trend <0.05). The number of pancreatic operations performed in the USA is increasing. Although being offered to older @entity1 with more comorbidities, surgeries are being performed with increasing safety and better outcomes.
