Abstract

PURPOSE: Hemorrhage following pancreatoduodenectomy is a severe, life-threatening complication. This study was conducted to suggest methods of the prevention and management of hemorrhagic complications.
METHODS
We reviewed medical records of 456 patients who had undergone pancreatoduodenectomy at Seoul National University Hospital between January 1991 and December 2000.
RESULTS
Postoperative bleeding occurred in 21 patients. Early hemorrhage within the postoperative 5th day amounted 5 cases, which were caused by improper intra-operative hemostasis. Three of these patients were saved by prompt surgery and, in one patient, conservative management. Late hemorrhage after the postoperative 5th day included 16 cases, of which 12 patients (75%) were associated with pancreas anastomotic leaks and 8 patients displayed pseudoaneurysm. "Sentinel bleeding" was evident in 8 cases. Angiographic embolization was performed in 8 cases, achieving hemostasis in 7 cases. Reoperations were attempted in 7 cases with complete hemostasis in 2 cases. As a result, 15 of 21 patients obtained complete hemostasis and mortality rate from postoperative hemorrhage was 28.6% (6/21).
CONCLUSION
Successful hemostasis was achieved by surgery in case of early hemorrhage and by angiographic embolization in late hemorrhage. In order to prevent hemorrhage following pancreatoduodenectomy, meticulous hemostasis and considerate operative techniques for avoiding pancreatic anastomotic leaks or vascular injury are essential.
