Chronic use of steroids further predisposes to stress ulcers. These pathologies sometimes coexist and identification of each is crucial for the appropriate treatment plan.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSION:<\/jats:title>\n The case allows for a learning opportunity focusing on coexisting pathologies which may be differentiated based on anatomical knowledge and patient presentation.<\/jats:p>\n <\/jats:sec>\n \n Highlights<\/jats:title>\n <\/jats:sec>","DOI":"10.1016\/j.ijscr.2015.09.038","type":"journal-article","created":{"date-parts":[[2015,10,21]],"date-time":"2015-10-21T01:54:09Z","timestamp":1445392449000},"page":"12-15","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Pneumoperitoneum, pneumoretroperitoneum, pneumomediastinum and extensive subcutaneous emphysema in a patient with ulcerative colitis"],"prefix":"10.1097","volume":"17","author":[{"given":"Usman T.","family":"Siddiqui","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hira","family":"Shahzad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asad Jamil","family":"Raja","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-5-20260114","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1007\/s00384-010-1005-7","article-title":"Subcutaneous emphysema, pneumomediastinum and pneumoperitoneum after diagnostic colonoscopy for ulcerative colitis: a rare but possible complication in patients with multiple risk factors","volume":"26","author":"Cappello","year":"2011","journal-title":"Int.
