Possibilities of Endovascular Hemostasis in Treatment of Pancreatic Bleeding

Pancreatic hemorrhage is one of the most severe complications of various pancreatic diseases that are difficult to treat even in multidisciplinary hospitals. Mortality from pancreatic hemorrhage can reach up to 80%. This study aimed to evaluate the possibility of maintaining endovascular homeostasis in the treatment of patients with pancreatic hemorrhage. This retrospective multicenter study included 45 patients (33 men and 12 women) in the age range of 27-84 years. More than 50% (n=23) of the patients were diagnosed with chronic pancreatitis. Malignant pancreatic lesions were observed in 22 patients; of whom11 patients had acute necrotizing pancreatitis. Acute bleeding was observed in 39 (86.6%) patients, and 6 (13.3%) patients showed chronic symptoms. Single-shot and recurrent bleeding was recorded in 22(48.9%) and 23 (51.1%) patients. In total, 57 patients underwent endovascular surgery. Moreover, 45 patients underwent primary surgery and another 12 (2.2%) underwent reoperation due to recurrent bleeding. Intraoperative complications occurred in 1 (2.2%) patient, and postoperative complications occurred in another. Out of all 45 patients, seven patients had 15 episodes of recurrent bleeding, of whom four patients showed recurrent bleeding at the in-hospital period, and the other three were under local supervision after the previous endovascular intervention. Out of the 45 patients, 35 (77.7%) survived and another 10 (22.2%) died due to multiple organ failure (n=8) and recurrent bleeding and hemorrhagic shock (n=2). Out of 10 patients who died, 4, 3, and 3patients showed malignant pancreatic lesions after surgery, acute pancreatitis, and chronic pancreatitis, respectively. Endovascular hemostatic interventions can significantly increase the survival rate in severe groups of patients with pancreatic bleeding. Endovascular hemostasis is a safe procedure and may be called the "method of choice" in the treatment of pancreatic bleeding, especially in combination with percutaneous draining, aspiration, and injection of liquid embolic agents into leakage of pancreatic juice.
