CERVICAL REMOVAL AT HYSTERECTOMY FOR BENIGN DISEASE - RISKS AND BENEFITS

An assessment of the risks and benefits of total and subtotal hysterectomy for benign disease was performed using the published literature, including a MEDLINE search, on all studies dealing with hysterectomy and related topics from 1946 to 1992. The shift from subtotal to total hysterectomy occurred before cytologic screening was accepted. Currently, SIL is diagnosed by cytology, evaluated by colposcopy and treated preferentially with cone biopsy. Prophylactic removal of the cervix does not eliminate the risk of cancer: it may shift the risk to the vaginal epithelium. The cervix has a role in sexual arousal and orgasm, probably due to stimulation of the Frankenhauser uterovaginal plexus. Bladder and bowel dysfunction following total hysterectomy may be related to loss of nerve ganglia closely associated with the cervix. Increased operative and postoperative morbidity, vaginal shortening, vault prolapse, abnormal cuff granulations and oviductal prolapse are other disadvantages of total hysterectomy. The cervix is not a useless organ and should not be removed during hysterectomy without a proper indication.
