Air\u2010contrast barium enema in 6 patients with history of anorectal disease or obstructed defecation demonstrated rectal diverticula. In these cases, multiple radiographs of the rectosigmoid region were obtained in upright position while the patient was relaxing or straining without any attempt to evacuate the barium. In 3 cases, the lateral rectal diverticula were incidental finding on CT studies that were performed for various unrelated abdominal complaints.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Pulsion type of diverticulum presenting as a wide\u2010neck outpouching was detected on the lateral rectal wall in 5 and on the posterior wall in 4 patients. They measured 2\u20133\u00a0cm in diameter when filled with contrast material or gas, and became even larger when the intraluminal pressure was increased by straining.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Pulsion diverticula of the rectum present as a wide\u2010neck outpouching of the lateral or posterior rectal wall in adult patients. This acquired abnormality is usually associated with coexisting anorectal lesions or defecation disorders. The practising radiologists and colorectal surgeons should be aware of this uncommon condition, its appearance on barium enema and other imaging studies, and its clinical implications.<\/jats:p><\/jats:sec>","DOI":"10.1111\/1754-9485.13154","type":"journal-article","created":{"date-parts":[[2021,2,21]],"date-time":"2021-02-21T00:57:01Z","timestamp":1613869021000},"page":"286-292","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pulsion diverticula of the rectum: Radiological diagnosis and clinical implications"],"prefix":"10.1111","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4506-4492","authenticated-orcid":false,"given":"Gary G","family":"Ghahremani","sequence":"first","affiliation":[{"name":"Department of Radiology University of California\u2010San Diego Medical Center San Diego California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ravinder K","family":"Mittal","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Division of Gastroenterology University of California\u2010San Diego Medical Center San Diego California USA<?oxy_comment_start comment&#x0003D;\"AUTHOR: Please check that authors and their affiliations are correct.\"?><?oxy_comment_end?><?oxy_comment_start comment&#x0003D;\"Correct\"?><?oxy_comment_end?>"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,2,19]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/795241"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326-5377.2009.tb02262.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0029-1236157"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01889215"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1148\/15.3.599"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/028418519503600118"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02054989"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02048163"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-013-0039-z"},{"key":"e_1_2_6_11_1","first-page":"1","article-title":"Why are diverticula of the rectum uncommon?
