He was a smoker. He underwent laparoscopic sigmoidectomy for pathological stage I sigmoid colon cancer and was followed up without any adjuvant therapy. Six months after his surgery, he complained of lower abdominal discomfort, bloody stools, and tenesmus. Colonoscopy showed extensive rectal ulcers between the anastomotic site and the anal canal, which was particularly severe on the anal side several centimeters beyond the anastomosis. We provided non-surgical management, including hyperbaric oxygen therapy. The rectal ulcers had healed 48\u00a0days after the therapeutic intervention. He has not experienced any recurrence for 3.5\u00a0years.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>While performing sigmoidectomy, it is important to consider the blood backflow from the anal side of the bowel carefully, especially for patients with risk factors of ischemic proctitis.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40792-021-01133-7","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T13:04:45Z","timestamp":1613999085000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ischemic proctitis 6\u00a0months after laparoscopic sigmoidectomy: a case report"],"prefix":"10.1186","volume":"7","author":[{"given":"Takuto","family":"Yoshida","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8934-9684","authenticated-orcid":false,"given":"Nobuki","family":"Ichikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigenori","family":"Homma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadashi","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin","family":"Emoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoichi","family":"Miyaoka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Matsui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akinobu","family":"Taketomi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,2,22]]},"reference":[{"key":"1133_CR1","doi-asserted-by":"publisher","first-page":"789","DOI":"10.1097\/00000658-197005000-00019","volume":"171","author":"JE Davis","year":"1970","unstructured":"Davis JE.
