[A Case of Cecal Cancer in a Patient with Situs Inversus Treated with Single-Port Laparoscopic Surgery].

A 67-year-old woman who had been treated for cardiac sarcoidosis was diagnosed with cecal cancer by detailed examination. Although an anatomical abnormality was present, we determined that a curative operation with single-port laparoscopic surgery(SILS)was feasible. We safely performed ileocecal resection with D3 lymph node dissection(operative time of 91 min with almost no intraoperative blood loss), and the patient developed no operation-related complications during the postoperative course. Although cecal cancer with situs inversus is very rare, SILS is thought to be safe and feasible when performed by surgeons, who are familiar with the SILS technique and the spatial-cognitive features of situs inversus.
