Located at the border of the transverse and descending colons, the anatomy of the left colonic angle is complex and characterized by numerous anatomic variations. Recent advances in preoperative (three-dimensional CT angiography with colonography) and\/or intraoperative (indocyanine green staining) imaging have allowed for a better identification of these variations. Methods: We performed a methodological review of studies assessing the anatomical variations of the left colic artery. Results: While the left colonic angle is classically vascularized by branches of the superior and inferior mesenteric arteries, an accessory middle colonic artery has been identified from 6 % to 36% of cases, respectively, leading to their classification of five types. In the absence of a left colic artery, this artery becomes predominant. In parallel to the variations in the venous drainage of the left colonic angle, which has been classified into four types, new lymphatic drainage routes have also been identified via this accessory artery and the inferior mesenteric vein. Conclusions: Collectively, these newly obtained findings plead for preoperative identification in cases of cancer of the left colonic angle and a surgical strategy adapted to these anatomical variations.<\/jats:p>","DOI":"10.3390\/jpm13081198","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T01:51:47Z","timestamp":1690509107000},"page":"1198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Revisited Surgical Anatomy of the Left Colonic Angle for Tailored Carcinologic Colectomy: A Review"],"prefix":"10.3390","volume":"13","author":[{"given":"Roukaya","family":"Belhadjamor","sequence":"first","affiliation":[{"name":"Department of Digestive Surgery, University Hospital of Caen, CS 30001, CEDEX 9, 14033 Caen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilles","family":"Manceau","sequence":"additional","affiliation":[{"name":"Department of Digestive and Oncology Surgery, Assistance Publique H\u00f4pitaux de Paris, Georges-Pompidou European Hospital, 75908 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Menahem","sequence":"additional","affiliation":[{"name":"Calvados Digestive Cancer Registry \u201cANTICIPE\u201d U1086 INSERM, Team Ligue Contre le Cancer, Centre Fran\u00e7ois Baclesse, University of Caen Normandy, 14000 Caen, France"},{"name":"P\u00f4le de Formation et de Recherche en Sant\u00e9, 2 rue des Rochambelles, 14032 Caen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Sabbagh","sequence":"additional","affiliation":[{"name":"Department of Digestive Surgery, University Hospital of Amiens, CHU Amiens Picardie, Rond point du Pr Cabrol, 80054 Amiens, France"},{"name":"UR7518SSPC (Simplification des Soins des Patients.
