Out of 284 patients with acute pancreatitis 73 (26%) had pancreas necrosis. Of these 73 cases 43 patients with infected pancreas necrosis were treated surgically, whereas conservative treatment proved successful in the remaining 30 cases with so-called sterile necrosis. Our interdisciplinary treatment combined delayed surgery for the better demarcation of the necrotic tissue, with extended intensive care therapy and epigastral laparostomy; through this laparostomy surgical revision with necrosectomy and peritoneal lavage was performed daily for 15 (+/- 6) days, necessitating long-term artificial respiration for an average of 15 (4/168) days. The mortality rate in the 43 patients with infected pancreas necrosis amounted to 16.2% (n = 7); none of the patients with sterile necrosis died. In cases of multiple organ failure the mortality rate was significantly higher (30%) than with failure of only one organ system (4.3%). The mortality rate in all cases with pancreas necrosis (n = 73) amounted therefore to 9.5%. Serious complications of laparostomy occurred in 28% (n = 12) of the 43 patients, whereby 8 of these cases were gastrointestinal fistulae, with a fatal outcome in one patient. The overall mortality rate in the total group of 284 patients with acute pancreatitis was 2.8%.
