[Two Cases of Digestive Organ Cancer in Patients with Situs Inversus Treated with Laparoscopic Surgery].

Case 1: A 53-year-old woman had a positive fecal occult blood test during an examination performed in June 2014, and she visited our department in August. Colonoscopic examination showed a type 2 rectal cancer 4 cm from the anal verge. CT showed situs inversus totalis. We performed laparoscopic abdominoperineal resection (D2) for a diagnosis of cT1b, N0, M0, Stage Ⅰrectal cancer. Case 2: A 60-year-old man had a positive fecal occult blood test. Colonoscopic examination showed a type 2 cancer of the ascending colon. Chest radiography showed dextrocardia, but the arrangement of the organs in the abdomen was normal. We performed laparoscopic ileocecal resection (D3) for a diagnosis of cT2, N0, M0, StageⅠ colon cancer. Laparoscopic surgery can be performed safely in patients with situs inversus totalis.
