Delayed massive hemorrhage after pancreaticoduodenectomy

Abstract

To summarize our clinical experiences of delayed massive hemorrhage (DMH), a rare but fatal complication, after pancreaticoduodenectomy (PD). The clinical data of 14 DMH patients at our medical center were collected and analyzed to evaluate the risk factors and to compare the efficacies of different therapies. A total of 1008 PD patients were treated since April 1993. Fourteen DMHs occurred post-operatively (1.4%). In these cases, 10/14 (71.4%) were complicated with pancreatic fistula. Sentinel bleeding was observed in 10 (71.4%) cases. The clinical manifestations of DMH included simple abdominal hemorrhage (n = 6, 42.9%), alimentary tract hemorrhage (n = 6, 42.9%) and both (n = 3, 21.4%). Shock (n = 2, 14.3%) might also be the initial symptom. Thirteen cases achieved post-therapeutic hemostasis while 1 patient died before re-admission. The therapeutic modalities included interventional therapy (n = 8) and surgery (n = 5). According to the therapeutic modalities, the re-bleeding rate, morbidity and final mortality of two groups were 50.0% vs 40.0% (P = 0.83), 75.0% vs 60.0% (P = 0.96) and 50.0% vs 80.0% (P = 0.62) respectively. Five patients survived at the end of treatment. The mortality rate was 71.4%. As a rare but fatal complication after PD, DMH is difficult to diagnose and treat. Postoperative pancreatic fistula remains a possible but undetermined risk factor. Sentinel bleeding is of great predicative value for DMH. Regular interventional arteriography is an effective method of improving diagnosis and treatment. Both interventional therapy and surgery may be used to treat DMH.
