ABSTRACT
Endoscopic retrograde cholangiopancreatography provides precise imaging of malignant biliopancreatic strictures and allows palliative treatment with endoscopic stenting. Initial successful biliary stenting can be achieved in about 69-100% of patients with pancreatic head malignancies. Preliminary data from our Clinic reported a much lower success rate of endoscopic biliary stenting in obstructive jaundice caused by pancreatic head malignancies. These findings may be because patients are referred at more advanced stages, which could contribute to the lower success rate of biliary stenting. We aimed to determine the success rate of endoscopic biliary stenting prospectively in 50 patients with pancreatic head malignancies and to asses if clinical, laboratory and ultrasound findings can be predictive of success and safety in biliary stenting. Initial successful biliary stenting was achieved in 70% of our patients. No major complications (perforation, severe pancreatitis, massive bleeding, death) were noted. We were able to identify factors predictive of a lower success rate which were associated with a more advanced disease and a longer delay before treatment. Based on our results, we conclude that ERCP should be offered without delay as a primary treatment option for all patients with unresectable pancreatic head malignancy and as a possible treatment option in patients with resectable malignancy who are poor candidates for surgery.
