Value of splenic preservation during distal pancreatectomy for chronic pancreatitis.

BACKGROUND: Pain relief after distal pancreatectomy for chronic pancreatitis is reportedly satisfactory in 50-80 per cent of patients. This study attempted to determine clinical and radiological features that might select patients likely to benefit from distal pancreatectomy, and whether splenic preservation influenced the outcome.
METHODS: Thirty-eight patients with chronic pancreatitis, who underwent distal pancreatectomy between 1982 and 1998, were reviewed retrospectively. The outcome of surgery was correlated with the aetiology of pancreatitis and radiological appearance on endoscopic retrograde cholangiopancreatography and computed tomography.
RESULTS: Good results were achieved in 23 of 36 patients for whom follow-up (median 48 months) was available, including all 11 with obstructive pancreatitis. The spleen was preserved in 22 patients. Twelve patients became diabetic after surgery: three of 20 in whom the spleen was preserved and nine of 16 who underwent splenectomy.
CONCLUSION: Non-alcoholic patients with a normal pancreas proximal to a dominant ductal stricture had a consistently good outcome from surgery. Spleen-preserving distal pancreatectomy, although technically demanding, can be performed safely with results equivalent to those of distal pancreatectomy with splenectomy or autotransplantation. Splenic preservation, apart from preventing postsplenectomy sepsis, might also delay the onset of diabetes.
