PATHOPHYSIOLOGY AND PROGNOSIS OF ACUTE PANCREATITIS
ーEARLY AND LATE PROGNOSTIC SIGNSー

The purpose of this study is to elucidate the pathophysiology of the acute pancreatitis and set up the criteria for assessing the severity of this disease.
One hundred and fifty seven cases of acute pancreatitis were treated at the First Surgical Department of Tokyo University Hospital and its affiliated hospitals. They consisted of 24 severe cases, 76 moderate cases, and 57 mild cases according to our classification. In early stage ten parameters, namely, abnormalities of white cell count, platelet count, hematcrit, lactic acid dehydrogenase, blood urea nitrogen, serum calcium, base excess, PaCO₂ and fasting blood glucose and age within 24 hours after admission and X-ray CT scan within 48 hours as early prognostic signs, enabled us to predict severe, moderate, or mild pancreatitis. More than 4 weeks later than the onset of acute pancreatitis, X-ray CT scan, white blood cell count, elevation of serum FDP level, endotoxemia and fall of plasma opsonic index served as good indicators to esaluate the severity of abdominal sepsis.
In experimental pancreatitis, CH₅₀ and opsonic index were remarkably decreased at 6 and 12 hours after induction of acute pancreatitis.
As the above results, determination of early prognostic signs immediately after onset and late prognostic signs 3－4 weeks after onset is very important to evaluate and manage the acute pancreatitis patients.
