OBJECTIVE: To introduce an alternative method for conization of the cervix using a Teflon-coated hot knife and to evaluate thermal distortion, adequacy of excision, operating time, blood loss, and short- and long-term effects of this method. METHODS: Between 1987-1993, 88 patients underwent cervical conization using a Teflon-coated hot knife at temperatures ranging from 110-130C. Histopathologic slides were reviewed simultaneously by two pathologists, who assessed thermal distortion, adequacy of excision, and interpretability of the surgical margins. Clinical information was obtained prospectively, including operating time, blood loss, and depth and volume of the excised cone. In addition, data were accumulated retrospectively from 40 randomly selected patients who underwent cold-knife conization between 1985-1990. Short- and long-term data were assessed for healing and scarring and the adequacy of postoperative Papanicolaou smears in the hot-knife patients. RESULTS: Thermal injury was minimal, with 300 mu or less in 83 patients (92%) and 350-600 mu in four patients. One patient had thermal distortion of 1500 mu. All slides were interpreted adequately. Blood loss was mild to moderate in 84 of 88 patients (95%) in the hot-knife group and in 34 of 40 patients (85%) in the cold-knife group. No patient in the hot-knife group needed blood transfusion or hospitalization. Operating time was reduced by as much as 67% when the hot knife was used. Thirteen percent of the hot-knife patients developed stenosis of the external os. No patient in the hot-knife group developed recurrence within 2 years of surgery. CONCLUSION: Using a Teflon-coated hot knife for conization of the cervix produces adequate surgical margins and reduces blood loss and operating time over that with cold-knife conization. Long-term follow-up reveals no increase in cervical stenosis and demonstrates adequate cytologic smears in the hot-knife patients.

Two cases of advanced (Stage III) carcinoid. tumors of the cervix are presented. Initial treatment in both cases consisted of combination chemotherapy (CCNU, cyclophosphamide and methotrexate) administered in the same regimen used in the treatment of small cell carcinoma of the lung. Initial response in the first case was remarkable, but toxic side effects delayed further treatment. Local tumor progression followed resulting in bilateral complete ureteric obstruction. Radiation therapy was discontinued before an effective dose could be delivered, and the patient expired in uremic coma. In the second case, initial response to chemotherapy was not as effective, but radiation therapy seemed to produce local control of the disease. Review of the English literature produced 21 additional cases of carcinoid tumors of the cervix: eight Stage I, seven Stage II, four Stage III, and one Stage IV. No firm conclusions with regard to therapy could be drawn from such small numbers.

Selective transcatheter embolization with Gelfoam pledgets was used to control intractable pelvic hemorrhage in two patients with gynecologic malignancy. There were no complications or sequelae associated with the procedure, and no further bleeding occurred. This method requires only Seldinger catheterization techniques under local anesthesia and should be considered in patients whose medical condition precludes major surgery or in whom operative ligation cannot be performed.
