Laparoscopic hemicolectomy in a patient with situs inversus totalis after open distal gastrectomy

Situs inversus totalis(SIT) is a rare anomaly in which the abdominal and thoracic cavity structures are opposite their usual positions.Occasionally,a few patients with a combination of this condition and malignant tumors have been encountered.Recently,several laparoscopic operations have been reported in patients with SIT.We report a case of an 83-year-old man with situs inversus totalis who developed colon cancer after open distal gastrectomy.Laparoscopic hemicolectomy with radical lymphadenectomy in such a patient was successfully performed by careful consideration of the mirror-image anatomy.Techniques themselves was not different from those in ordinary cases.Thus,curative laparoscopic surgery for colon cancer in the presence of situs inversus totalis is feasible and safe.
