ARDENGH, José Celso et al. A rare case of recurrent acute pancreatitis after EUS-FNA in a patient with pancreatic intraepithelial neoplasia type 2. Rev. gastroenterol. Perú [online]. 2019, vol.39, n.2, pp.183-186. ISSN 1022-5129.

Pancreatic intraepithelial neoplasia (PanIN) is considered a pre-malignant lesion difficult to identify by imaging methods. EUS- FNA is an effective technique to obtain material for histopathological study of pancreatic cystic tumors, but it is not free of adverse events. We report a case of a 56 years old patient, with chronic abdominal pain (early 1994). MRI showed pancreatic cystic images. The etiologic diagnosis was doubtful and EUS-FNA was performed. Immediately after a FNA, patient had an episode of acute pancreatitis, requiring hospitalization. During one year after FNA he had five episodes of AP. A new EUS suspected of PanIN, which was confirmed by surgery. After surgery the patient is well and has no more episodes of AP. Although the risk of AP, EUS-FNA should be performed to determine the best treatment for these patients with chronic abdominal pain who have cystic changes of pancreatic gland.
