In the absence of known and underlying systemic disease, efficient and coordinated clinical work\u2010up and evaluation for comorbid diagnoses associated with pneumoperitoneum can serve to guide management and avoid unnecessary surgery for stable and asymptomatic patients.<\/jats:p>","DOI":"10.1155\/cris\/5524896","type":"journal-article","created":{"date-parts":[[2025,6,4]],"date-time":"2025-06-04T09:49:45Z","timestamp":1749030585000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Persistent Asymptomatic Pneumoperitoneum With Spontaneously Resolving Idiopathic Pneumatosis Intestinalis: A Case Report"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5224-0810","authenticated-orcid":false,"given":"John P.","family":"Ratanawong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7375-2042","authenticated-orcid":false,"given":"Tzu Han","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5738-2974","authenticated-orcid":false,"given":"Torben H.","family":"Urdahl","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Weir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony T.","family":"Rezcallah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,4]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/rjab138"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/RHU.0b013e3181ffeb49"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000022461"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2019.08.015"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/rjv035"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinimag.2021.02.011"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.06.1309"},{"key":"e_1_2_10_8_2","first-page":"41","article-title":"Nonsurgical Causes of Pneumoperitoneum","volume":"170","author":"Mularski R.
