Morbidity, mortality, and technical factors of distal pancreatectomy

Background: Pancreatic leak is a major source of morbidity associated with pancreatic surgery. We sought to identify disease and technique-dependent factors associated with morbidity and mortality after distal pancreatectomy. Methods: Retrospective review of patients who underwent distal pancreatectomy during a 5-year period. Clinical, technical, and pathologic data were correlated with operative morbidity or mortality. Results: Fifty-one patients underwent distal pancreatectomy for primary pancreatic disease, extrapancreatic malignancy, or trauma. Overall perioperative mortality and morbidity rates were 4% and 47%, respectively. Pancreatic leak was the most common complication, occurring in 26% of patients. Overall complications and pancreatic leaks occurred more often after distal pancreatectomy for trauma and in patients with a sutured pancreatic stump closure. Conclusions: Distal pancreatectomy can be performed with a low rate of mortality, though pancreatic leak is a common cause of morbidity. The urgency of the procedure and the method of pancreatic stump closure may influence postoperative morbidity.
