Objective: To evaluate short-term and long-term outcomes of the transcervical hysteroscopic ablation of endometrial polyps. Design: A prospective clinical study. Setting: Gynecology-Obstetrics Ward, Regional Hospital, Pardubice. Methods: The study included 283 patients in whom in the period of September 1997 to June 1999 hysteroscopic ablations of the endometrial polyp were performed. The mean age of the collection was 58.3 years. 78.2% operations were performed as an outpatient procedure. We evaluated short-term outcomes, longterm outcomes and complications 5 years after the procedure. The patients were examinated by vaginal ultrasound 6 months after operation and then repeatedly in 12 months intervales. Short-term outcome: There were performed 283 hysteroscopic ablations of the endometrial polyp in the period from September 1997 to June 1999. In one case (0.35%) the operation was complicated by uterine perforation without necessity of any intervention, in 6 cases (2.12%) the procedure was finished in the second session. In 3 patients (1.06%) the endometrial polyp showed malignant transformation. Long-term outcome: In 252 cases (89.05%) we did not notice any long-term complication. In the other cases (10.95%) the endometrial pathology was found by the vaginal sonography and it was necessary to perform other intervention. In 2 cases (0.71%) endometrial cancer was found. Conclusion: Hysteroscopic ablation of the endometrial polyp is at present fully indicated method for treatment of this pathology. The follow up by vaginal sonography is an elementary condition for the early diagnosis of the long-term complications.
