Hemosuccus Pancreaticus: A Rare Bleeding Pseudoaneurysm of the Inferior Pancreaticoduodenal Artery Treated with Embolization

Hemosuccus pancreaticus as a rare cause of gastrointestinal bleeding

Hemosuccus pancreaticus is a life-threatening condition that should be considered in patients with abdominal pain, gastrointestinal hemorrhage and high serum amylase. The varied presentation of hemosuccus pancreaticus and the limited literature evidence due to its rarity make it challenging to diagnose. Diagnostic modalities include contrast-enhanced computed tomography scans, endoscopic procedures (esophagoduodenoscopy and endoscopic retrograde cholangiopancreatography) and angiography. Therapeutic management through an interventional radiology using coil embolization is safe and effective in hemodynamically stable patients with hemosuccus pancreaticus. Endosonography can be an innovative approach for the diagnosis and treatment of patients in whom contrast cannot be administered; however, its safety and efficacy need to be confirmed by future studies. This review presents current views on the diagnosis and treatment of patients with hemosuccus pancreaticus.

Gastrointestinal bleeding caused by rupture of a posterior inferior pancreaticoduodenal artery pseudoaneurysm: A case report

BACKGROUND

Gastrointestinal bleeding caused by a ruptured pancreatic pseudoaneurysm is rare, and a pseudoaneurysm of the posterior inferior pancreaticoduodenal artery is especially rare. A 68-year-old man was hospitalized after presenting intermittent black stools and dyspnea accompanied by severe anemia. Angiographic examination revealed that Pseudoaneurysm of the posterior inferior pancreaticoduodenal artery.

METHODS

Angiography was performed and revealed a pseudoaneurysm of the posterior inferior pancreaticoduodenal artery. Subsequently, a blood transfusion and endovascular embolization were performed.

RESULTS

The patient's gastrointestinal bleeding stopped, and the hemoglobin level remained stable. During 1 year of follow-up, the patient remained in a generally good condition.

CONCLUSION

posterior inferior pancreaticoduodenal artery pseudoaneurysmIt is rare and difficult to diagnose, gastrointestinal bleeding is a serious complication, vascular interventional embolization is effective.

Life-Threatening Upper Gastrointestinal Hemorrhage in Hemosuccus Pancreaticus: A Case Report

Hemosuccus pancreaticus (HP) is a rare cause of upper gastrointestinal bleeding caused by bleeding from the ampulla of Vater into the duodenum. HP most commonly results from a rupture of pseudoaneurysms secondary to chronic pancreatitis. The low incidence of HP and the wide spectrum of its clinical presentation poses diagnostic challenges. We present a case of a 39-year-old male with acute-on-chronic pancreatitis resulting in HP and obstructive jaundice due to pancreatic pseudocyst with secondary hematoma. This case highlights the rare occurrence of hypovolemic shock due to massive hemorrhage in HP and the successful management with prompt cardiovascular support and angiographic coil embolization of a bleeding pancreatic pseudoaneurysm.
