Accurate diagnosis is not always possible; up to 8% of surgical procedures are performed in benign pancreatic masses presumed to be malignant. Objectives: We aimed to compare clinical and imaging characteristics of resected focal type 2 AIP, CP, and PCa and identify factors that could improve preoperative differential diagnosis. Methods: Charts from patients that underwent pancreatic resection under suspicion of PCa between 2000 and 2014 were reviewed. Clinical and imaging data were recorded. Subjects were grouped as type 2 AIP, CP, and PCa. Results: We included 79 cases; 41 men, mean age of 57.3\u00a0years\/old \u00b1 15.6 SD. Pathology report was type 2 AIP (20%), CP (10%), and PCa (70%). According to international consensus criteria for AIP 11 cases were deemed probable type 2 and 5 as unspecific pancreatic mass. A nondilated main pancreatic duct (MPD) was associated with AIP (OR 9.3; 95% CI 3.05\u201328.7), p &lt; 0.001; obstructive jaundice (OR 28.5; 95% CI 8.18\u201379.5); and a dilated MPD (OR 5.21; 95% CI 1.9\u201314.6) suggested malignancy. Conclusions: In the setting of undetermined pancreatic focal mass, a nondilated MPD suggests the diagnosis of type 2 AIP.<\/jats:p>","DOI":"10.1159\/000497140","type":"journal-article","created":{"date-parts":[[2019,2,13]],"date-time":"2019-02-13T22:01:50Z","timestamp":1550095310000},"page":"137-143","source":"Crossref","is-referenced-by-count":5,"title":["A Nondilated Main Pancreatic Duct Predicts Type 2 Autoimmune Pancreatitis: Comparative Study of Resected Pancreatic Head Masses"],"prefix":"10.1159","volume":"101","author":[{"given":"Mario","family":"Pel\u00e1ez-Luna","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Medina-Campos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Uscanga-Dom\u00ednuez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Hernandez-Calleros","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Chan-Nu\u00f1ez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Negrete","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arturo","family":"Angeles","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2019,2,13]]},"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/dig\/article-pdf\/101\/2\/137\/4027686\/000497140.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/dig\/article-pdf\/101\/2\/137\/4027686\/000497140.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:14:50Z","timestamp":1745424890000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000497140"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,2,13]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2020,3,3]]},"published-print":{"date-parts":[[2020,3,11]]}},"URL":"https:\/\/doi.org\/10.1159\/000497140","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"type":"print","value":"0012-2823"},{"type":"electronic","value":"1421-9867"}],"subject":[],"published":{"date-parts":[[2019,2,13]]}}}
