Distal pancreatectomy: what is the standard for laparoscopic surgery?
OBJECTIVE
Distal pancreatectomy (DP) is performed for a range of benign and malignant lesions. Accurate pre-operative diagnosis can be unreliable and morbidity remains high. This study evaluates a 12-year, single-centre experience with open DP to review indications, diagnoses and associated morbidity.


METHODS
Retrospective review of patients who underwent DP at a UK-based tertiary referral centre between 1994 and 2006.


RESULTS
Sixty-five patients (mean age 49.9 years) had final diagnoses of chronic pancreatitis +/- pseudocyst (n= 22), benign cystadenoma (n= 15), neuroendocrine tumour (n= 8), primary pancreatic carcinoma (n= 6) and 14 other conditions. DP performed for presumed cystic neoplasm (n= 24) revealed a correct pre-operative diagnosis in 71% of patients. Histological examination confirmed that 59% of resected cystic tumours were either malignant or had malignant potential. When DP was undertaken for presumed pseudocyst (n= 12), 83% of cases were correctly diagnosed pre-operatively. Overall mortality and morbidity rates were 3% and 39%, respectively, with five patients (8%) developing a clinically significant pancreatic fistula. Ten (17%) patients developed diabetes mellitus and nine (14%) required long-term pancreatic exocrine supplementation.


CONCLUSIONS
Open DP can be performed with acceptable morbidity, low mortality and preservation of pancreatic function in the majority of cases, setting the standard for laparoscopic techniques.
