BACKGROUND Post-pancreaticoduodenectomy haemorrhage is a potentially life-threatening complication. Delay in the detection and subsequent management of complications contribute significantly to post-operative mortality and morbidity associated with pancreaticoduodenectomy. METHODS All patients undergoing pancreaticoduodenectomy at an Australian-based tertiary referral center between 2017 and 2022 were reviewed retrospectively. We identified those patients who suffered a post-pancreaticoduodenectomy haemorrhage and further analysed those patients who had their post-pancreaticoduodenectomy haemorrhage identified on repeated CT imaging performed within 24 h of their previous CT scan. RESULTS A total of 232 pancreaticoduodenectomies were identified for analysis during the study period, of which 23 patients (9.9%) suffered a post-pancreaticoduodenectomy haemorrhage. We present four patients who had their post-pancreaticoduodenectomy haemorrhage identified on repeat CT scan in the setting of a recent (within 24 h) CT scan which showed no evidence of active haemorrhage or pseudoaneurysm formation. All patients received prompt and definitive endovascular management through stent insertion or coil embolization resulting in successful cessation of bleeding. Three patients made an uncomplicated recovery thereafter. Unfortunately, one patient died as a complication of the bleed despite early and definitive endovascular intervention. CONCLUSION Our study highlights the importance of having a low threshold for repeated CT imaging in the post-pancreaticoduodenectomy setting, particularly when there remains a high index of suspicion clinically for a post-operative complication, even in the context of previous benign imaging. Given the complexity of pancreaticoduodenectomy, we believe early detection with liberal imaging allows the best chance at successfully managing the morbidity and mortality associated in the post-pancreaticoduodenectomy setting.
