A total of 159,264 eligible patients who underwent ERCP were identified, of which 137,158 (86.12%) were normal weight, 12,522 (7.86%) were obese, and 9584 (6.02%) were morbidly obese. The primary outcome was in\u2010hospital mortality. The secondary outcomes were the length of stay, total cost, and ERCP\u2010related complications. Multivariate analysis and propensity score (PS) matching analysis were performed. The analysis was repeated in a restricted cohort to eliminate confounders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients with morbid obesity, as compared to normal\u2010weight patients, were associated with a significantly higher in\u2010hospital mortality (hazard ratio [HR]: 5.54; 95% confidence interval [CI]: 1.23\u201325.04). Obese patients were not associated with significantly different mortality comparing to normal weight (HR: 1.00; 95% CI: 0.14\u20137.12). Patients with morbid obesity were also found to have an increased length of hospital stay and total cost. The rate of ERCP\u2010related complications was comparable among the three groups except for a higher cholecystitis rate after ERCP in obese patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Morbid obesity but not obesity was associated with increased mortality, length of stay, and total cost in patients undergoing ERCP.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ueg2.12070","type":"journal-article","created":{"date-parts":[[2021,5,6]],"date-time":"2021-05-06T16:11:10Z","timestamp":1620317470000},"page":"561-570","source":"Crossref","is-referenced-by-count":7,"title":["Morbid obesity but not obesity is associated with increased mortality in patients undergoing endoscopic retrograde cholangiopancreatography: A national cohort study"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6058-9529","authenticated-orcid":false,"given":"Bing","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Medicine Mount Sinai Morningside and Mount Sinai West  New York City New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8300-8291","authenticated-orcid":false,"given":"Chia\u2010Hung","family":"Yo","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine Far Eastern Memorial Hospital  New Taipei City Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4854-7913","authenticated-orcid":false,"given":"Ramya","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Medicine Mount Sinai Morningside and Mount Sinai West  New York City New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8508-9371","authenticated-orcid":false,"given":"Bolun","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Medicine John H.
