Unfortunately, they also share the issues related to a delay in diagnosis, including inappropriate management and poor outcomes. Advancements have been made in our understanding of the aetiologies of both conditions. Several predisposing factors linked to critical illness have been implicated in <jats:styled-content style=\"fixed-case\">ACPO<\/jats:styled-content>. <jats:styled-content style=\"fixed-case\">CIPO<\/jats:styled-content> is a functional motility disorder, historically misdiagnosed, with unnecessary surgery being performed in many patients with dire consequences. This review discusses the pathophysiology, clinical and diagnostic features, and treatment of each. For <jats:styled-content style=\"fixed-case\">ACPO<\/jats:styled-content>, a safer pharmacological approach to treatment is presented in a modified up\u2010to\u2010date algorithm. The importance of <jats:styled-content style=\"fixed-case\">CIPO<\/jats:styled-content> as a differential diagnosis when seeing patients with recurrent admissions for abdominal pain and distention is also discussed, as well as specific indications for surgery. While surgery is often a last resort, the role of the surgeon in the management of both <jats:styled-content style=\"fixed-case\">ACPO<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">CIPO<\/jats:styled-content> cannot be undervalued. By characterizing each condition in a common review, the knowledge gleaned aims to optimize outcomes for these frequently complex patients.<\/jats:p>","DOI":"10.1111\/ans.13148","type":"journal-article","created":{"date-parts":[[2015,5,6]],"date-time":"2015-05-06T08:13:31Z","timestamp":1430900011000},"page":"709-714","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Acute and chronic pseudo\u2010obstruction: a current update"],"prefix":"10.1111","volume":"85","author":[{"given":"Maria\u2010Pia","family":"Bernardi","sequence":"first","affiliation":[{"name":"Division of Cancer Surgery Peter MacCallum Cancer Centre  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satish","family":"Warrier","sequence":"additional","affiliation":[{"name":"Division of Cancer Surgery Peter MacCallum Cancer Centre  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
