We presented a case of transmural rectosigmoid ischemia in a patient who had not undergone any significant interventions and had no underlying diseases. Conservative treatment methods were unsuccessful, and surgical resection was necessary to prevent the development of gangrene or sepsis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>Upon arrival at our health center, a 69-year-old man reported experiencing left lower quadrant pain and rectorrhagia. The CT scan revealed thickening in the sigmoid and rectum. Subsequent colonoscopy revealed circumferential ulcers, severe edema, erythema, discoloration, and ulcerative mucosa in both the rectum and sigmoid. Due to persistent severe rectorrhagia and worsening pathologic parameters, another colonoscopy was performed three days later.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>Initially, conservative treatments were administered, but as the tenderness worsened, surgical exploration of the abdomen was necessary. During the procedure, a large ischemia from the sigmoid to the rectal dentate line was observed, and the lesion was resected. A stapler was then inserted into the rectum, followed by the use of the Hartman pouch method to deviate the tract. Finally, colectomy, sigmoidectomy, and rectal resection were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Due to the worsening pathological condition of our patient, surgical resection was necessary. It is important to note that rectosigmoid ischemia, although rare, can develop without a known underlying cause. Therefore, it is crucial to consider and evaluate potential causes beyond the most common ones. Furthermore, any pain or rectorragia should be assessed immediately.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2023.108372","type":"journal-article","created":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T00:58:08Z","timestamp":1685494688000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["A case report of transmural rectosigmoid ischemia in an elderly patient"],"prefix":"10.1097","volume":"107","author":[{"given":"Mehran","family":"Ebrahimi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akram","family":"Arabi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shahriar","family":"Dabiri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seyed Ali","family":"Razavinasab","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas Pour","family":"Pasandi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Zeidabadi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R3-70-20260318","doi-asserted-by":"crossref","first-page":"998","DOI":"10.3390\/diagnostics11060998","article-title":"Large bowel ischemia\/infarction: how to recognize it and make differential diagnosis?
