Optimizing the Management Strategies of Delayed Postpancreaticoduodenectomy Hemorrhage

Objective: To optimize the management strategies of delayed postpancreaticoduodenectomy hemorrhage (PPH) by evaluating data from a high-volume pancreatic center. Background: Delayed PPH is a potentially lethal complication. The management of delayed PPH remains controversial. Methods: Patients who underwent pancreaticoduodenectomy between July 2018 and June 2023 were identified from an institutional database. The clinical scenarios, management, and outcomes of patients with delayed PPH (>5 days postoperatively) were analyzed. Results: Of the 2013 patients who underwent elective pancreaticoduodenectomy, 130 (6.5%) with delayed PPH were identified. The overall mortality was 15.4%. The success rates of endoscopy, angiographic intervention, and relaparotomy in treating delayed PPH were 54.5%, 56.5%, and 68.8%, respectively. For PPH from the hepatic arteries or their branches, complete blockade of the common or proper hepatic artery (C/PHA) was performed in 17 patients, either by coil embolization (n=7) or surgical ligation (n=10). Coil embolization of the C/PHA resulted in significant infarction of the left liver in 2 patients. No postoperative liver infarction occurred in patients who underwent ligation of the C/PHA during relaparotomy. Ten patients underwent suture repair of the C/PHA 13 times during relaparotomy. Arterial ligation achieved a significantly higher success rate of hemostasis than suture repair of the C/PHA during relaparotomy (100% vs 30.8%, P <0.001). Conclusions: Angiography should be attempted first in managing hemodynamically stable delayed PPH. Arterial ligation was preferred for bleeding from the hepatic arteries during relaparotomy with minor consequences for the liver.
