[Biodegradable Pancreatic Stent in Endoscopic Resection of an Ampulloma in Argentina: A Case Report]

Periampullary tumors are characterized by their low incidence and are often incidental findings during endoscopic procedures performed for other reasons. Among these, ampullary adenomas carry a potential for malignant transformation, making early detection and timely treatment essential. The choice of resection method primarily depends on the size of the lesion and the degree of deep-layer infiltration, factors that may hinder endoscopic resection and lead to the need for surgical management. Endoscopic resection is usually performed via endoscopic retrograde cholangiopancreatography, and the placement of a pancreatic stent is an effective preventive measure to reduce the risk of post-procedural pancreatitis, one of the most common complications. We present the first documented case in Argentina of endoscopic resection of an ampullary adenoma with placement of a biodegradable pancreatic stent.
