Summary
Sixty-eight patients were entered into a prospective randomised study comparing the anatomical outcome and adequacy of colposcopic and cytological examination when two types of suture were used to secure haemostasis after cone biopsy of the uterine cervix.
After cone biopsy the new squamo-columnar junction was visualised in only 28 per cent of patients whereas it had been visualised in 48 per cent before the procedure. Only 32 per cent of post-cone smears contained endocervical or metaplastic cells whereas 85 per cent of pre-cone smears did so.
When cone specimens longer than 25 mm had been removed a suture technique partly inverting the cone bed was advantageous in that it improved the subsequent visibility of the squamo-columnar junction.
No difference in the incidence of cervical stenosis related to suture technique was demonstrated.
