We encountered a case of rectal cancer with coexisting Retzius shunt and inferior mesenteric AVM successfully treated with laparoscopic surgery. Contrast computed tomography (CT) in a 62\u2010year\u2010old man with rectal cancer showed multiple dilated veins at the mesenterium of the descending sigmoid colon. These dilated veins were connected between the IMV and the left renal vein. A diagnosis of Retzius shunt was made, and laparoscopic low anterior resection with lymph node dissection was performed. A pathological examination of the colonic mesenterium revealed AVM communicating with the dilated IMV and Retzius shunt. The preoperative evaluation of aberrant vessels by three\u2010dimensional CT is particularly useful for patients with vascular malformations to ensure safe laparoscopic surgery.<\/jats:p>","DOI":"10.1111\/ases.13220","type":"journal-article","created":{"date-parts":[[2023,6,21]],"date-time":"2023-06-21T07:50:14Z","timestamp":1687333814000},"page":"761-765","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Laparoscopic surgery for rectal cancer with a coexisting Retzius shunt and inferior mesenteric arteriovenous malformation: A case report"],"prefix":"10.1111","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1886-3449","authenticated-orcid":false,"given":"Shunsuke","family":"Furukawa","sequence":"first","affiliation":[{"name":"Department of Surgery Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7619-9923","authenticated-orcid":false,"given":"Masatsugu","family":"Hiraki","sequence":"additional","affiliation":[{"name":"Department of Surgery Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michiaki","family":"Akashi","sequence":"additional","affiliation":[{"name":"Department of Pathology Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoya","family":"Kimura","sequence":"additional","affiliation":[{"name":"Department of Surgery Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukihiko","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Radiology Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryuichiro","family":"Samejima","sequence":"additional","affiliation":[{"name":"Department of Surgery Japanese Red Cross Society Karatsu Red Cross Hospital  Karatsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"105","article-title":"Bemerkungen unter anastomosen zwischen der pfortader und untern hohlader ausserhalb der leber","volume":"5","author":"Retzius AA","year":"1835","journal-title":"Ztschr Physiol"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2022.106831"},{"key":"e_1_2_9_4_1","first-page":"23","article-title":"Vascular lesion of portal cirrhosis","volume":"5","author":"Macindoe AH","year":"1928","journal-title":"Arch Pathol Lab Med"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.139.5.1013"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/hep.1840090127"},{"key":"e_1_2_9_7_1","first-page":"534","article-title":"Operative mesenteric arteriography in the search for the site of bleeding in unexplained gastrointestinal hemorrhaging","volume":"48","author":"Margulis AR","year":"1960","journal-title":"Surgery"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.3919\/jjsa.77.1720"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40792-019-0583-z"}],"container-title":["Asian Journal of Endoscopic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ases.13220","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T02:10:01Z","timestamp":1696212601000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/ases.13220"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,6,20]]},"references-count":8,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2023,10]]}},"alternative-id":["10.1111\/ases.13220"],"URL":"https:\/\/doi.org\/10.1111\/ases.13220","archive":["Portico"],"relation":{},"ISSN":["1758-5902","1758-5910"],"issn-type":[{"value":"1758-5902","type":"print"},{"value":"1758-5910","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,6,20]]},"assertion":[{"value":"2023-01-09","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-06-09","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-06-20","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
