Simultaneous Laparoscopic Colectomy and Nephrectomy for Synchronous Ascending Colon Cancer and Right Kidney Cancer: Report of a Case

Laparoscopic surgery has been widely applied to various surgical procedure, becoming standard procedure for colorectal and kidney cancer. Here, we describe a case of simultaneous laparoscopic surgery for synchronous colorectal and kidney cancer. A 70-year-old female was diagnosed with a tumor in the right lower abdomen. An abdominal CT showed tumors in the ascending colon and the right kidney. A colonoscopy demonstrated ascending colon cancer, and the patient was diagnosed synchronous ascending colon and right kidney cancer. Laparoscopic surgery was performed in cooperation with urologists. A right hemicolectomy was performed first at a lithotomy position. A right radical nephrectomy was then performed after changing to the left lateral position. The operation time was 450 minutes, and the blood loss was 60 ml. Chylous ascites were confirmed, but conservatively improved after surgery. Although synchronous colorectal and kidney cancers have not been confirmed in many cases, it is estimated that such synchronous cancers will increase with the aging of society and development of improved diagnostic imaging techniques. Therefore, simultaneous laparoscopic surgery is a safe and minimally invasive procedure with detailed surgical planning and a sophisticated surgical technique, including ensured port setting and body positioning, in cooperation with urologists.
