Laparoscopic right colectomy for a patient with situs inversus totalis.

Situs inversus totalis (SIT) is rare congenital anomaly characterized by an inversion of the thoracic and abdominal viscera that crates a mirror image. Recently, several laparoscopic operations have been reported in patients with SIT. We herein report the case of a 76-year-old woman with ascending colon cancer who received a laparoscopic right colectomy. She was discharged on the 12th day after the operation, without any complications. Laparoscopic surgery in the patients with SIT remains a technical challenge for the surgeon. However, careful understanding of mirror image anatomy and planning of laparoscopic procedure permitted safe operation using technique in ordinary cases. Thus, laparoscopic surgery for colon cancer in the patients with SIT is safe and feasible.
