[Study of operative indication and timing for acute necrotizing pancreatitis].

65 patients of acute necrotizing pancreatitis were reported. 36 patients underwent operation with a mortality of 27.8%. However the mortality in 29 patients treated nonoperatively, the mortality was 3.4% because of their less critical condition. In operation group 7 out of 17 patients died (41.2%) with positive results in bacterial smear or culture while all 5 patients with negative results survived. The time from onset to admission in the survivor and the dead was 33 hours and 85 hours respectively. The time from onset to operation was 41 hours in the survivor while 138.8 hours in the dead. So the prognosis related closely to early intensive care therapy and if indicated, surgical intervention timely. The indication and timing of operation were discussed.
