Background Long-term functional outcome after operative treatment of necrot
izing pancreatitis (NP) has not been studied extensively.
Methods Pancreatic function, performance status, recurrence of symptoms and
other related problems were analysed in 44 consecutive patients successful
ly discharged from hospital after operative necrosectomy (1983-1995) and fo
llowed up completely for a mean of 5 years.
Results Clinical pancreatic insufficiency developed in half the patients. D
iabetes mellitus (11 patients), steatorrhoea (six) or both (five) were asso
ciated with a mean estimate of 52, 66 and 67 per cent parenchymal necrosis
respectively. Normal pancreatic function was associated with 27 per cent pa
renchymal necrosis (P<0.05). Diabetes worsened while steatorrhoea tended to
improve over time. Abdominal pain and pancreatitis recurred in six and two
patients respectively. Performance status worsened in four patients becaus
e of recurrent pancreatitis and severe steatorrhoea. Poor long-term perform
ance was associated with a higher Acute Physiology And Chronic Health Evalu
ation II score on admission (mean 14 versus 9).
Conclusion NP has prominent effects on long-term pancreatic exocrine and en
docrine function in half the patients, but most preserve a good overall fun
ctional status. The development of pancreatic insufficiency varies with the
extent of pancreatic parenchymal necrosis.
