Is surgical treatment of severe acute pancreatitis : timing of operation crucial for survival? Context: In patients operated on for severe acute pancreatitis (SAP) the impact of the timing of operation on outcome is controversial. In a retrospective analysis of a prospectively documented database, we studied 250 patients suffering from SAP, who were in need for surgical treatment during their course of disease. From 1982 to 1998, 250 patients with the diagnosis of SAP who required operative treatment were admitted to the intensive care unit (ICU) of a university hospital. The mean APACHE II score on the day of admission was 16.1 (8-35). One hundred eighty-five patients (74%) required reoperation, of whom 111 patients (60%) underwent reoperation on demand and 74 (40%) patients a pre-planned reoperation. Overall mortality was 38.8% (97 patients). In patients who were operated during the first three weeks after onset of disease, mortality was significantly higher than in patients who were operated after three weeks (46% vs. 25%, p < 0.01). Besides patient age (p < 0.05), APACHE II score at admission (p < 0.01), multiple organ dysfunction (p < 0.01), infection of pancreatic necrosis (p < 0.05), surgical control of pancreatic necrosis (p < 0.0001), and the time of surgical intervention (p < 0.05) determined survival significantly.

Patients who were operated later than three weeks after onset of disease had a significantly better outcome. In patients suffering from SAP who required surgical treatment, the timing of operation is crucial for survival. Final Decision: yes
