Simultaneous laparoscopic radical nephrectomy and laparoscopic sigmoidectomy for synchronous renal cell carcinoma and colonic adenocarcinoma.

Hand-assisted laparoscopic radical nephrectomy is an established therapeutic choice for localized renal cell carcinoma. Laparoscopic sigmoidectomy is becoming accepted for the treatment of locally advanced sigmoid colon cancer. Primary cancer may occur synchronously in two different organs, in which case simultaneous resection is recommended if possible. To our knowledge this is the first report of simultaneous laparoscopic resection of coexistent renal and colonic double primary malignant tumors.
