title: Prevention of post-cone biopsy cervical stenosis using a temporary cervical stent.
abstract: Stenosis of the residual cervix is not an infrequent complication of cone biopsy which may result in subfertility, problems with adequate follow-up and dysmenorrhoea. In an attempt to minimize this complication a temporary indwelling cervical support stent has been developed. This is sutured into the exposed cone bed immediately after cutting the cone specimen and removed 2 weeks later. A pilot study using this device in 33 cold knife conizations has been performed. There were no primary or secondary haemorrhages and no post-conization pelvic infections. At follow-up, 6 months after cone biopsy two patients (6%) had clinical cervical stenosis, and one patient (3%) complained of dysmenorrhoea (although the cervix was not stenosed). The cervical transformation zone was fully visible in 21/33 patients (64%) (95% CI 48 to 80) and follow-up smears contained endocervical cells in 20/33 patients (61%) (95% CI 44 to 78). These results compare very favourably with historical controls from the same unit and suggest that cone biopsy support stents should now be assessed in a prospective randomized trial.
