She had been admitted for the majority of the previous 5 months for recurrent pancreatitis and had undergone a cholecystectomy. Additional symptoms included nausea, anorexia, constipation, and a 40-lb weight loss over 4 months. She appeared uncomfortable, and an examination was remarkable for tachycardia, hypertension, and diffuse abdominal tenderness to light palpation. Her initial laboratory test results revealed mildly elevated liver enzymes (aspartate aminotransferase 68 U\/L, alanine aminotransferase 80 U\/L) and a normal lipase. She was admitted for pain control and nutritional support. Over the next few days, the lipase increased to 1707 U\/L. Despite optimizing her management for acute pancreatitis, the patient\u2019s symptoms persisted. Further history gathering and laboratory testing ultimately revealed her diagnosis. Our expert panel reviews her hospital course and elucidates the management of our eventual diagnosis.<\/jats:p>","DOI":"10.1542\/peds.2017-1332","type":"journal-article","created":{"date-parts":[[2018,4,10]],"date-time":"2018-04-10T07:30:11Z","timestamp":1523345411000},"source":"Crossref","is-referenced-by-count":1,"title":["An 18-Year-Old With Acute-on-Chronic Abdominal Pain"],"prefix":"10.1542","volume":"141","author":[{"given":"Mark H.","family":"Corden","sequence":"first","affiliation":[{"name":"Division of Hospital Medicine and"},{"name":"Department of Pediatrics, Keck School of Medicine, University of Southern California, Los Angeles, California;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamie","family":"Frediani","sequence":"additional","affiliation":[{"name":"Children\u2019s Center for Cancer and Blood Diseases, Department of Pediatrics, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Xu","sequence":"additional","affiliation":[{"name":"The Pediatric Group of Southern California, Agoura Hills, California;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quin Y.","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Digestive Diseases Center, Cedars-Sinai Medical Center, Los Angeles, California; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiu-Yi Emily","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Keck School of Medicine, University of Southern California, Los Angeles, California;"},{"name":"Department of Anesthesiology Critical Care Medicine, Children\u2019s Hospital Los Angeles, Los Angeles, California;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
