However, POCUS is not always acceptable to all physicians. To address the benefits and importance of POCUS, numerous studies have examined the use of POCUS in clinical practice and even medical education. This article aims to highlight the effects of POCUS as an extension of the physical examination, and we present a case to address the reasons it should be performed. For a man experiencing abdominal pain immediately after his feeding jejunostomy tube was changed, there was high suspicion of small-bowel volvulus after a \u201cwhirlpool sign\u201d was observed during the POCUS, whereby mesenteric vessels presented in a whirling or spiral shape. This impression was subsequently confirmed by computed tomography. Small-bowel volvulus is a rare complication of changing a feeding jejunostomy tube. The images submitted here add to the sparse evidence from the literature on the use of POCUS as an extension of the physical examination for evaluating abdominal pain. POCUS can be used after taking the patient\u2019s history and conducting a physical examination. The observation of a whirlpool sign may indicate the presence of a volvulus that is life-threatening.<\/jats:p>","DOI":"10.3390\/diagnostics12051153","type":"journal-article","created":{"date-parts":[[2022,5,6]],"date-time":"2022-05-06T02:46:39Z","timestamp":1651805199000},"page":"1153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Point-of-Care Ultrasonography as an Extension of the Physical Examination for Abdominal Pain in the Emergency Department: The Diagnosis of Small-Bowel Volvulus as a Rare Complication after Changing the Feeding Jejunostomy Tube"],"prefix":"10.3390","volume":"12","author":[{"given":"Tse-Chyuan","family":"Wong","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, China Medical University Hospital, Taichung 404, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhu-Chia","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, China Medical University Hospital, Taichung 404, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian-Xun","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Chang Gung Memorial Hospital and Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tzu-Heng","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Chang Gung Memorial Hospital and Chang Gung University, Taoyuan 333, Taiwan"},{"name":"Department of Emergency Medicine, New Taipei Municipal Tucheng Hospital, New Taipei City 236, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Jun","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, China Medical University Hospital, Taichung 404, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Te-Fa","family":"Chiu","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, China Medical University Hospital, Taichung 404, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7625-7193","authenticated-orcid":false,"given":"Shih-Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, China Medical University Hospital, Taichung 404, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"703","DOI":"10.1016\/j.emc.2021.07.005","article-title":"Abdominal Pain in the Emergency Department: Missed Diagnoses","volume":"39","author":"McCoin","year":"2021","journal-title":"Emerg.
