Abstract
The most common cancer in women worldwide is cervical cancer. For early-stage disease the standard treatment is radical hysterectomy.
One of the main issues faced by surgeons performing a radical hysterectomy is the wide variation in the terminology used to define the procedure and the nomenclature used to describe the anatomical spaces critical to the success of the surgery. The aim of this review was to synthesize currently used anatomical landmarks with relation to surgical avascular spaces for the performance of radical hysterectomy.A computer-based comprehensive review of the MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, and SciSearch databases, as well as National Comprehensive Cancer Network and European Society of Gynaecological Oncology guidelines, was performed.
With all relevant data collected, and previous anatomical studies during surgeries and on cadavers performed by authors, a manuscript of the definition of avascular spaces, methods of dissection, and anatomical limits was prepared.Avascular pelvic spaces developed during radical hysterectomy, such as the paravesical, pararectal, ureter tunnel, and paravaginal, were considered and included in the manuscript. A clear definition of avascular spaces may aid a better understanding of the anatomical aspects of the radical hysterectomy.
It could improve surgeon knowledge of the structures that need to be preserved and those that need to be resected during a radical hysterectomy. Additionally, the detailed exposure of anatomical boundaries will facilitate the appropriate tailored radicality depending on the risk factors of the disease.
Moreover, knowledge of these spaces could make pelvic surgery safer and easier for other types of gynecological and non-gynecological procedures.
