Abstract

PURPOSE: The surgical morbidity and mortality after a pancreaticoduodenectomy has been decreasing but still remains high. The most serious complications are pancreatic leakage, gastrointestinal or intra-abdominal hemorrhage, and an intraabdominal abscess. The less serious complications are delayed gastric emptying and wound problems. The aim of this study was to evaluate the risk factors for morbidity and mortality after a pancreaticoduodenectomy.
METHODS
Among 90 patients who underwent pancreaticoduodenectomy from Feb. 1992 to Dec, 2000. 68 patients whose hospital records could be reviewed thoroughly were enrolled in this study. The postoperative morbidity and mortality after a pancreaticoduodenal resection were evaluated in terms of the patient's age, combined disease, laboratory values, biliary drainage, transfusion, types of pancreaticojejunostomy, pancreatic duct size, consistency, and the administration of octreotide. Univariate and multivariate analysis were performed with a chi-square test and multiple logistic regression test.
RESULTS
Postoperative complications were observed in 43 cases (63.2%). Wound complications were noted in 13 cases (19.1%), gastric emptying disturbance in 10 cases (14.7%), bleeding in 9 cases (13.2%), an abscess in 4 cases (5.9%), and leakage in 22 cases (32.4%). Nine cases (13.2%) had died. The causes of death were sepsis due to leakage in 3 cases, bleeding in 3 cases, and others causes in 3 cases. Univariate analysis showed that diabetes mellitus was significantly (P<0.05) related to delayed gastric emptying. In multivariate analysis, transfusion was significantly (P<0.05) related to wound infections and mortality. Old age ( 65 years) was significantly related to leakage and delayed gastric emptying.
CONCLUSION
Pancreaticoduodenectomy is still associated with a high mortality and morbidity rate even though there has been significant progress in the field of pancreatic surgery and postoperative follow-up. Old age and transfusions appeared to be the main risk factors for morbidity and mortality after a pancreaticoduodenectomy in this study. In addition to these factors, better anticipation and management of the postoperative complications is essential for improving the surgical outcome.
