ABSTRACT
OBJECTIVE:
To determine the efficacy and morbidity of fine loop diathermy excision of the cervical transformation zone as applied to the management of outpatients with abnormal cervical smears.DESIGN:
Prospective programme trial with six month follow up.SETTING:
Two hospital based colposcopy clinics. PATIENTS 616 Patients aged 16-60 with abnormal cervical smears.INTERVENTIONS:
After colposcopic and cytological assessment excision of the cervical transformation zone by fine loop diathermy under local anaesthesia in the outpatient department. MAIN OUTCOMEMEASURES:
Time to complete the treatment, immediate morbidity in terms of discomfort and bleeding, and cytological and colposcopic findings at six months.RESULTS:
Treatment was completed in a mean of 3.47 minutes (SD 1.99). Immediate morbidity was minimal, and histological specimens were adequate in over 90% of cases. Almost two thirds of patients were treated at their first visit to the clinic. 58 Patients (9.4%) failed to attend for follow up at six months and one had had a hysterectomy. Of the 557 patients who attended for colposcopic and cytological follow up at six months, 506 (91%) were normal cytologically and 19 (3.4%) had histologically confirmed persistence of cervical intraepithelial neoplasia. The overall confirmed failure rate of the technique was 4.4%.CONCLUSION:
Loop diathermy excision is an effective treatment with low morbidity and is an appropriate modality for patients with abnormal cervical smears.
