Nerve sparing radical hysterectomy: latest developments and historical perspective

Abstract

Autonomic nerve damage during surgery is thought to play a crucial role in the aetiology of bladder dysfunction, sexual dysfunction and colorectal motility disorders which are seen in patients after radical hysterectomy. In order to prevent these complications, Japanese gynaecologists introduced a surgical technique with preservation of the pelvic autonomic nerves in the 1960s. In the 1980s the first English paper was published. Since then several surgical approaches have been described, i.e. liposuction, electrical stimulation to locate nerves intra-operatively and laparoscopically assisted techniques. Recently, more attention is being paid to the importance of sparing the sympathetic hypogastric nerve. All authors report results on small cohorts of patients. The incidence of urinary dysfunction seems very low after nerve sparing. Sparing the autonomic nerves during radical hysterectomy seems feasible and safe in both Japanese and Western patients. Literature review does not provide strong clues for a compromised radicality and cure due to nerve sparing. Future larger clinical trials will have to decide whether the technique of nerve sparing radical hysterectomy could be implemented as a standard treatment for cervical cancer patients.
