SIR 2003 film panel case 6: hemosuccus pancreaticus secondary to chronic pancreatitis

Endovascular treatment of arterial bleeding in patients with pancreatitis

PURPOSE

To assess the technical and clinical success of endovascular treatment of arterial bleeding in pancreatitis.

MATERIALS AND METHODS

From 1992 to 2005, 28 patients with pancreatitis underwent endovascular treatment of associated arterial lesions. Fifteen patients were affected by acute pancreatitis and 13 by chronic pancreatitis. The diagnosis was obtained according to medical history and clinical and laboratory evidence of disease. Arterial involvement was diagnosed by non-invasive imaging and angiography. After treatment, all patients underwent CT scanning at a minimum of 15, 30 and 90 days. We evaluated the feasibility of embolization and patients' survival at 90 days.

RESULTS

Transcatheter embolization was feasible in 26/28 patients (93%). In 2 patients with acute pancreatitis, selective catheterization failed so we could not proceed with the angiographic approach. After treatment, there were 3/26 rebleeds (11.5%), all of whom died within the first week. At 90 days' follow-up, 21/26 patients (81%) were alive. Two of 26 patients (8%) suffered splenic complications. Among the 13 patients with acute pancreatitis, 8 (61.5%) were alive after 90 days. All 13 patients with chronic pancreatitis were alive after 90 days.

CONCLUSIONS

Comparing our results with the surgical literature, we found that embolization is less invasive and, at least, as successful as surgery. Thus, it should be considered the first choice in pancreatitis arterial complications.

Hemosuccus Pancreaticus as a Rare Complication of Bariatric Surgery

Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding from the duct of Wirsung into the duodenum via the ampulla of Vater. Hemosuccus pancreaticus is difficult to diagnose because the bleeding is usually intermittent, and the clinical findings are often discordant. Patients present with pain, either left upper quadrant or epigastric, and bleeding, which may present as melena, bright red blood per rectum, or even shock, if the hemorrhage is severe. Hemosuccus pancreaticus is usually caused by rupture of a pseudoaneurysm of a peri-pancreatic artery, often the splenic artery, in the setting of pancreatitis; other causes are very rare. In this report, for the first time to our knowledge, we present a case of hemosuccus pancreaticus that occurred as a complication of bariatric surgery.

Differential diagnosis of gastrointestinal bleeding

In this article, we review the many causes of gastrointestinal (GI) bleeding and discuss current strategies for rendering a specific diagnosis. Diagnostic tools considered in this review include: clinical assessment, upper endoscopy, colonoscopy, scintigraphy, and conventional arteriography as well as computed tomography angiography and magnetic resonance angiography. An algorithm for the diagnostic work-up of the patient with GI bleeding is included.

Hemosuccus pancreaticus: a rare cause of gastrointestinal bleeding

AIM

The purpose of this study was to analyze the diagnostic and therapeutic features of hemosuccus pancreaticus.

METHODS

We conducted a retrospective study of nine patients (eight men and one woman, mean age 60 yrs) admitted to surgery or gastroenterology units for hemossucus pancreaticus between 1981 and 2003. The following were studied: symptoms, contribution of established morphologic exams (upper digestive endoscopy, computed tomography (CT) and selective digestive angiography) and treatment.

RESULTS

Hemosuccus pancreaticus occurred in chronic alcoholic pancreatitis (N=8) and chronic familial pancreatitis (N=1). Seven patients (77.8%) presented overt digestive bleeding (one melena, two hematochezia, two melena with hematochezia, one hematemesis, one hemorrhagic shock). The inaugural sign was anemia in one patient and epigastric pain in another. An upper digestive endoscopy, performed in eight patients (88.9%), revealed fresh red blood in the first or second duodenum in three and hemossucus pancreaticus in three others. Arteriography was performed in eight patients (88.9%) and CT angiography in one. Surgery was performed in 5 patients (55.6%), after embolization in one. Embolization was effective in 3 patients. Therapeutic abstention proved successful in one patient. There were no deaths.

CONCLUSIONS

Hemosuccus pancreaticus is a rare cause of digestive bleeding. Upper digestive endoscopy and selective digestive angiography during active bleeding can provide the diagnosis. Endovascular treatment can control an unstable hemodynamic situation before elective surgery to prevent recurrence, which can be more severe than the first event.
