[A Case of Concurrent Robotic-Assisted Partial Nephrectomy and Laparoscopic Ileocecal Resection for Synchronous Cancer of the Kidney and Ascending Colon].

: We report a case of synchronous cancer of the kidney and ascending colon that was resected concurrently using roboticassisted partialnephrectomy and laparoscopic ileocecalresection. A man in his 70s was diagnosed as having renaland ascending colon cancers. Thus, simultaneous resection was planned. First, robotic partial nephrectomy was performed via a transabdominalapproach by the urologicalsurgeon. After changing the position from semi-lateraldecubitus to supine, severalports were added and laparoscopic ileocecal resection was performed. Robotic and laparoscopic surgery was performed simultaneously, and the benefits of minimally invasive surgery were obtained.
