Abstract
A 52-year-old man admitted for palpitation and exertional dyspnea was found by our internal medicine department to have anemia and sigmoid colon carcinoma. The patient had situs inversus (Kartagener syndrome), and preoperative diagnosis of complicated anomalies were right-sided heart, two-lobe lung, multiple spleens, IVC defect and intestinal malrotation. Surgical findings were left-sided liver, right-sided stomach, total situs inversus, and nonrotational intestinal malrotation in which the cecum was on the median. Since sigmoid colon carcinoma inveded the cecum we conducted sigmoidectomy with ileocecal resection. The man was discharged on postoperative day 18. Situs inversus is a rare congenital disease and often has several complicated anomalies. Although this case involved sigmoid colon carcinoma with some complicated anomalies, no severe problems occurred during surgery.
