Delayed massive hemorrhage after pancreatic and biliary surgery: embolization or surgery?

Area of Science:

• Gastroenterology and Hepatobiliary Surgery
• Surgical Critical Care
• Hemorrhage Management

Background:

• Delayed massive hemorrhage (DMH) is a significant cause of mortality following major pancreatic and biliary surgery.
• While overall mortality has decreased, effective management strategies for DMH are crucial.
• This study analyzes DMH management, focusing on embolization and surgical interventions.

Purpose of the Study:

• To analyze the management of delayed massive hemorrhage (DMH) after major pancreatic and biliary surgery.
• To assess the role of embolization versus surgical intervention in managing DMH.
• To identify factors influencing outcomes in patients experiencing DMH.

Main Methods:

• A comparative study analyzing 1010 patients undergoing pancreatic or biliary surgery (1994-2002) against a historical control group of 686 patients (1983-1993).
• Exclusion of cholecystectomy procedures from the study cohort.
• Analysis of DMH incidence, associated complications (sepsis, sentinel bleed), treatment modalities (embolization, surgery), and overall mortality.

Main Results:

• The incidence of DMH slightly decreased from 3.2% to 2.3% but was not statistically significant.
• Septic complications and sentinel bleeds were common preceding DMH, with no significant difference between groups.
• Embolization was rarely employed (2/2 patients in the study group), while surgical intervention for hemostasis showed comparable success rates and overall mortality between the groups.

Conclusions:

• The incidence of DMH has seen a modest decline, with sepsis and sentinel bleeds being frequent precursors.
• Embolization was underutilized in DMH management despite its recognized role.
• Aggressive surgical intervention remains the preferred treatment for delayed massive hemorrhage post-pancreatic and biliary surgery.
