Although these anomalies are mostly asymptomatic, they should be identified preoperatively to avoid iatrogenic injury. We report a case of sigmoid colon cancer in a patient with both anomalies. The patient was an 80-year-old man whose preoperative computed tomography (CT) scan showed that the IVC ascended vertically along the left side of the abdominal aorta, and the descending colon was at the abdominal midline. Coronal CT was particularly useful for visualizing these anomalies. With this better understanding of the malpositioned anatomy, we successfully performed laparoscopic sigmoidectomy with lymph node dissection. Careful evaluation of preoperative CT imaging based on a clear understanding of such anatomical anomalies is particularly important for performing safe laparoscopic surgery.<\/jats:p>","DOI":"10.1093\/jscr\/rjaa259","type":"journal-article","created":{"date-parts":[[2020,6,23]],"date-time":"2020-06-23T11:13:22Z","timestamp":1592910802000},"source":"Crossref","is-referenced-by-count":7,"title":["Laparoscopic sigmoidectomy for sigmoid colon cancer with left-sided inferior vena cava and persistent descending mesocolon"],"prefix":"10.1093","volume":"2020","author":[{"given":"Masayo","family":"Kawakami","sequence":"first","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidetsugu","family":"Nakazato","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Tomiyama","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takehiko","family":"Tomori","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Miyagi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seiji","family":"Nagayoshi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Ohmine","sequence":"additional","affiliation":[{"name":"Department of Surgery, Okinawa Red Cross Hospital, Okinawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,7,31]]},"reference":[{"key":"2020073110470483100_ref1","doi-asserted-by":"crossref","first-page":"873","DOI":"10.1016\/S0090-4295(99)00007-2","article-title":"Anomalies of the inferior vena cava and renal veins: embryologic and surgical considerations","volume":"53","author":"Mathews","year":"1999","journal-title":"Urology"},{"key":"2020073110470483100_ref2","doi-asserted-by":"crossref","first-page":"327","DOI":"10.1148\/86.2.327","article-title":"Persistent descending mesocolon","volume":"86","author":"Popky","year":"1966","journal-title":"Radiology"},{"key":"2020073110470483100_ref3","doi-asserted-by":"crossref","first-page":"1003","DOI":"10.2214\/ajr.180.4.1801003","article-title":"CT diagnosis of volvulus of the descending colon with persistent mesocolon","volume":"180","author":"Chen","year":"2003","journal-title":"Am J Roentgenol"},{"key":"2020073110470483100_ref4","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1186\/1756-0500-6-42","article-title":"Anal protrusion of an ileocolic intussusception in an adult with persistent ascending and descending mesocolons: a case report","volume":"6","author":"Ongom","year":"2013","journal-title":"BMC Res Notes"},{"key":"2020073110470483100_ref5","first-page":"459","article-title":"Laparoscopic colectomy for persistent descending mesocolon: an experience of 13 patients","volume":"18","author":"Okada","year":"2013","journal-title":"J Jpn Soc Endosc Surg"},{"key":"2020073110470483100_ref6","doi-asserted-by":"crossref","first-page":"206","DOI":"10.1259\/0007-1285-47-556-206","article-title":"Congenital anomalies of the inferior vena cava.
