retroperitoneal lymph node dissection
Also written as: RPLND — Retroperitoneal Lymph Node Dissection
Surgical removal of lymph nodes located behind the peritoneum, including para-aortic and paracaval nodes, for staging and treatment of gynecologic cancers.
Full Definition
Retroperitoneal lymph node dissection involves the systematic surgical removal of lymph nodes located in the retroperitoneal space, primarily the para-aortic and paracaval lymph node chains. This procedure is an important component of comprehensive staging for advanced gynecologic cancers, particularly ovarian, endometrial, and cervical cancers. The dissection typically extends from the level of the renal vessels to the bifurcation of the aorta and may include sampling or complete removal of nodes in specific anatomic regions. The procedure can be performed through open, laparoscopic, or robotic approaches, and provides crucial prognostic information while potentially offering therapeutic benefit through removal of microscopic disease.
Usage
Usage note: Specify the extent of dissection (e.g., up to renal vessels) and number of nodes removed.
