title: Evidence-based surgery in chronic pancreatitis.
abstract: BACKGROUND
  In the past two decades our knowledge of the pathophysiology and surgical treatment options in chronic pancreatitis has improved substantially. Surgical treatment in chronic pancreatitis has evolved from extending to organ-preserving procedures.
  
  
  CONCLUSIONS
  The classical Whipple resection is no longer a standard procedure in chronic pancreatitis, and is continuously being replaced by operations such as the duodenum-preserving pancreatic head resection and pylorus-preserving Whipple. These procedures allow the preservation of exocrine and endocrine pancreatic function, provides pain relief in up to 90% of patients, and contributes to an improvement in life quality.
  
  
  CONCLUSIONS
  In addition to presently available results from randomized controlled trials, new studies comparing available surgical approaches in chronic pancreatitis are needed to determine which procedure is the most effective in the treating chronic pancreatitis.
