Abstract
Here we report a case of ascending colon tumor in a patient with situs inversus totalis treated by laparoscopy-assisted colectomy. A 56-year-old woman was referred to our hospital for a positive fecal occult blood test. She was diagnosed with a laterally spreading tumor at the ascending colon. Chest radiography and computed tomography (CT) revealed situs inversus totalis. We performed a laparoscopy-assisted colectomy with no serious complications. The tumor was pathologically diagnosed as well differentiated adenocarcinoma, fTis(M), fN0, fH0, fM0, fP0, fStage 0. Preoperative three-dimensional CT findings provided useful information such as tumor location and its relationship with the feeding arteries that enabled us to perform laparoscopic surgery safely in a patient with situs inversus totalis.
