Our aim was to define a group of patients with B-AP to facilitate their diagnosis and management, while more judiciously using medical resources. (2) Materials and Methods: This retrospective, large cohort study, which was conducted by extracting data from the BUC-API registry, consisted of 1855 cases between 1 June 2015 and 1 April 2022. Each admission of the same patient was considered a separate case if it did not have signs of chronic pancreatitis. Severity and morphology were stratified according to the Revised Atlanta Classification. (3) Results: A total of 732 cases of B-AP were analyzed, with 92.5% occurring at the first attack. The median age was 65 years, with 61.9% of the patients being female. The majority (82.2%) were surgical cases, and the length of stay (LoS) was 7 days. There were 10.2% severe cases, with a mortality rate of 4%. (4) Discussion: We found positive associations between sex, age, recurrence, and morphology and biliary etiology. Compared with the general population, female sex and age over 65 years correlate better with a biliary etiology. In most scenarios, patients suffer from first attacks, with a lower probability of developing local complications. There was a tendency for biliary pancreatitis patients to be admitted to surgical wards.<\/jats:p>","DOI":"10.3390\/life15020139","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T06:53:32Z","timestamp":1737442412000},"page":"139","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Epidemiology of Biliary Acute Pancreatitis\u2014A Seven-Year Experience of a Large Tertiary Center"],"prefix":"10.3390","volume":"15","author":[{"given":"Andrei Vicen\u021biu","family":"Edu","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Internal Medicine & Gastroenterology Department, University Emergency Hospital of Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7052-4294","authenticated-orcid":false,"given":"Mihai Radu","family":"Pahomeanu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Internal Medicine & Gastroenterology Department, University Emergency Hospital of Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8388-5198","authenticated-orcid":false,"given":"Alexandru","family":"Ol\u0103reanu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4828-2979","authenticated-orcid":false,"given":"Dana Gabriela","family":"Corbu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreea Ramona","family":"Treteanu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru","family":"Constantinescu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Internal Medicine & Gastroenterology Department, University Emergency Hospital of Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6206-6126","authenticated-orcid":false,"given":"Vasile","family":"\u0218andru","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Gastroenterology Department, Emergency Clinical Hospital of Bucharest, 014461 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Narcis Octavian","family":"Z\u0103rnescu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Abdominal Surgery Department, University Emergency Hospital of Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3042-0754","authenticated-orcid":false,"given":"Lucian","family":"Negreanu","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Carol Davila University of Medicine and Pharmacy Bucharest, 050474 Bucharest, Romania"},{"name":"Internal Medicine & Gastroenterology Department, University Emergency Hospital of Bucharest, 050098 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, T., Qin, C., Zhao, B., Li, Z., Zhao, Y., Lin, C., and Wang, W.
