Comparison of single-port laparoscopy and conventional laparoscopy for extraperitoneal para-aortic lymphadenectomy.

Background Extraperitoneal para-aortic lymphadenectomy (PAL) is used to treat gynecological cancers. This laparoscopic approach was first described using a multiport technique, and more recently, a single-port technique was developed. Our aim was to experimentally compare both approaches—conventional laparoscopy (CL) and single-port laparoscopy (SPL)—via the extraperitoneal laparoscopic approach.
