[A useful technical device to improve the sampling of uterine cervical conization].

Standardized procedures regarding the sampling of cervical conization are extensively described in the Literature. The cervical cone dimension depends on the surgical technical approach and on the extension of the dysplasic/neoplastic lesion. Current sampling procedures frequently turn out to be of problematic correct realization, with special regard to small size cervical cones and to fixed material with subsequent artefactual tissue coarctation. Here we describe a simple device, which makes the cone sampling procedure easier and more accurate, allowing better oriented and better recomposed samples. Perpendicular sections to the cervical lumen allow in fact an accurate evaluation of the lesion's depth and of the status of the resection surgical borders. After conization, preventive agreements with the surgeon provide that, before fixation, a 2-3 mm in diameter smooth plastic probe is inserted into the cervical channel, from the external cervical os to the conization apex (a fragment of the handle of an endocervical cytological brush can be used). The insertion of such a "specillum" must be performed with warning gently since superficial cervical epithelium, especially if dysplasic (overall in case of severe dysplasia), is particularly subjected to mechanical abrasions. The preventive insertion of the endocervical probe makes the cone sampling more manageable, in fact the cervical channel is slightly dilated and the subsequent fixation hardens the cone tissues. After the "specillum" extraction, the cervical lumen appears clearly visible; in such a situation, the endocervical cone apex will be exactly sampled, and the subsequent seriated clockwise sampling of the residual cone will be more smoothly performed, with following preparation of adequate histological sections 4. In our experience such a simple and easy-to-apply device, proves to be useful in making the uterine cone sampling more accurate and comfortable.

Prevalence and risk factors for residual cervical neoplasia in subsequent hysterectomy following LEEP or conization.

OBJECTIVES: The purposes of the present study were to determine the prevalence of residual disease in the hysterectomy specimens following cold knife conization (CKC) or loop electrosurgical excision procedure (LEEP) and to evaluate the predictive factors for residual disease. DESIGN: Descriptive study SETTING: Department of Obstetrics and Gynecology, Faculty of Medicine, Siriraj Hospital. SUBJECTS: A total of 120 patients who underwent hysterectomy after either LEEP or CKC. MATERIAL AND METHOD: The medical records of 120 women were reviewed to estimate the prevalence of residual disease.. The patients' characteristic and pathologic parameters were analyzed for the risk factors of residual disease. Chi square test and Student t test were used for statistical analysis. RESULTS: Of the 120 patients, 46 cases had residual disease in their hysterectomy specimens so the prevalence was 38.3% (95% CI 29.5, 47.2). Invasive cervical cancer was found in the hysterectomy specimens in 4 cases (8.7%). Only ectocervical margin was the predictive factor of residual disease in the hysterectomy specimen (p = 0.002). Age, conization pathologic findings, glandular involvement, endocervical margin status, stromal invasion, and endocervical curettage results were not predictive factors for residual disease in the hystectomy specimens. CONCLUSION: Residual disease was found in 38.3% of hysterectomy specimens after conization. Also undiagnosed invasive cervical cancer was found. Careful examination for residual disease in hysterectomy specimens should be performed, especially among those with positive cone margin.

Diagnostic and therapeutic technique of cervical conization with "cold knife" using fibrin glue. Preliminary outcomes.

In recent years many Authors have proposed several techniques and surgical tools to perform conical or cylindrical excisions of the portio and cervical canal. For instance, we can perform conization using a traditional "cold knife" (scalpel), CO2 laser with focal bundle, radiothermic or fine needle electroconization (Loop Electrosurgical Excision Procedure-LEEP-; Large Loop Excision of Transition Zone-LLETZ-). Our goal has been to change traditional conization of the cervix with "cold knife" using Hegar dilatators to delineate the cone we have to remove and prevent lesions in the cervical canal; furthermore, using fibrin glue (Tissucol-R) to do a considerable haemostasis. The performance takes about five minutes under local anaesthesia and it has been possible to study the patients with a 24-month follow up. The results the Authors obtained have been low blood loss, diagnostic and histological accuracy, better colposcopic follow-up, any angle-shots or abnormality of the cervical canal and any physical-chemical modifications of the ovulatory cervical mucus. The advantages of traditional conization we modified are still valid; however, others procedures have a clinical and therapeutical significance but concerning histological and diagnostic investigations they could give a negative result.

Prophylactic cerclage in pregnancy. Effect in women with a history of conization.

OBJECTIVE: To evaluate the effect of prophylactic cerclage on the course of pregnancy in women with prior conization. STUDY DESIGN: In a retrospective, observational study, the outcome of pregnancies in 69 women with (n = 30) and without (n = 39) cerclage who previously underwent conization was evaluated regarding hospitalization due to threatened preterm labor and delivery before 37 weeks of gestation. RESULTS: The occurrence of preterm delivery was 23.3% in the cerclage group and 20.5% in the control group (P = .78). Women with prophylactic cerclage were hospitalized significantly more often due to threatened premature labor: with cerclage, 66.7%; without cerclage, 33.3% (P = .006). CONCLUSION: Prophylactic cerclage should be used more sparingly in women with a history of conization because it does not prevent premature delivery and tends to induce preterm uterine contractions.

A new surgical instrument for diathermic conization of the uterine cervix.

A surgical instrument for uterocervical diathermic conization has been constructed for adequate treatment of patients with mild to severe dysplasia (CIN I-III) of the uterine cervix. The purpose of the instrument is to provide a simple means of performing a differentiated conization tailored to the anatomy of the patient and the extent of the disease. With this instrument conization of the uterine cervix may be performed on an out-patient basis. It includes a mount holder member for a diathermic wire that fits into a pistol grip. The wire is held in tension by the mount so that the wire forms an angle alpha to the longitudinal axis of the mount. The wire then cuts out a cone when the mount is turned through a complete revolution. Angle alpha of the wire may be adjusted on the mount thus enabling variation in the size and shape of the cone that is excised.

[Condylomatous lesions of the uterine cervix: LLETZ conization].

Eight cases are reported about women with the diagnosis of HPV related lesions; a "dot-blot" hybridization technique with radioactive probes was done with each of them, also a conization with a diathermic loop (LLETZ) and a post operative follow-up with methods such as Pap smear, colposcopy and hybridization. We think the way we manage HPV related lesions has the advantage of an accurate diagnosis, with the exact envolved HPV type, and it discards the possibility of an infiltrating carcinoma, after studying the conization sample. Hybridization techniques are complementary to Pap smear in order to know the infective viral type and to exclude a possible occult infection in the post-operative period. LLETZ conization ended up as a quick and easy technique with no postoperative problems and with a proved efficiency, since neither recurrences were found (with citology) nor viral DNA was detected, the technique is not too complicated and takes about 30 minutes.

Laser conization of cervical intraepithelial neoplasia grade 3: free resection margins indicative of lesion-free survival.

BACKGROUND: Various grades of cervical intraepithelial neoplasia may occur following laser conization for grade 3 lesions. The aim of this study was to assess lesion-free survival after laser conization in cases with/without free resection margins, and to test whether detection of human papillomavirus infection and/or p53 expression in the cone lesion were useful predictors of lesion-free survival. METHODS: In 598 women treated for cervical intraepithelial neoplasia grade 3 the state of the resection margins was recorded and related to the findings on follow-up, up to 15 years post-operatively. Lesion-free survival times were analyzed by the Kaplan-Meier method. The presence/absence of human papillomavirus infection and/or p53 expression in the primary lesion was investigated in every fifth case by in situ hybridization and immunohistochemistry respectively. RESULTS: Lesion-free survival was significantly more common after complete than incomplete excision of cervical intraepithelial neoplasia. In the latter, lesions tended to appear shortly after surgery, indicating the presence of residual disease. The few lesions appearing later were evenly divided between those with and those without complete excision. The results of the human papillomavirus and p53 investigations added no further information. CONCLUSIONS: The presence of cervical intraepithelial neoplasia in the cone margin gives strong indication of potential treatment failure. In its absence laser conization is highly effective in the treatment of cervical intraepithelial neoplasia, and has the advantage of providing a specimen suitable for the necessary histological investigation.

Laser conization: the results of treatment of cervical intraepithelial neoplasia.

Combination laser conization was performed for the treatment of cervical intraepithelial neoplasia (CIN) in 473 patients, who were followed for a mean period of 70 months. In 16 cases (3.4%) CIN was demonstrated during follow up, and in 10 cases (2.1%) within the first year after treatment. The grade of CIN in the cone specimen was of no predictive value to recurrence. When excisional margins were involved recurrence was observed in 8.7% of cases, compared to 2.3% when margins were uninvolved. The risk of recurrence was significantly higher in patients with involvement of the endocervical cone margin. The only case of invasive disease during follow-up was observed more than 2 years after conization; cone biopsy was without involved margins. The results clearly demonstrate the method to be effective and justify an expectant management of all patients after conization by this method.

The efficiency of the cytobrush and cotton swab in obtaining endocervical cells in smears taken after conization of the cervix.

In a randomised study of cervical smears after conization, the efficacy of the combined wooden spatula and cytobrush was compared with that of the combined wooden spatula and cotton swab. The conization technique involved a could knife and two Sturmdorf sutures. A total of 75 women participated, 57 had smears taken with both methods. Eighteen with only one of the methods. Out of 66 taken with a wooden spatula and a cytobrush. 48 (72.7%) contained endocervical cells and 53 (80.3%) contained either endocervical or metaplastic cells. Out of 66 smears taken with a wooden spatula and a cotton swab, only 25 (37.9%) contained endocervical cells and 40 (60.6%) contained endocervical or metaplastic cells. Both differences were significant (P less than 0.001 and P less than 0.05, respectively). The combined use of a wooden spatula and cytobrush is recommended for cytological smears after conization.

Preoperative hot conization of the cervix: a possible method to reduce postoperative febrile morbidity following vaginal hysterectomy.

Laboratory results indicate that the endocervix may be a source of bacterial contamination when vaginal hysterectomy is performed. In a series of 160 consecutive vaginal hysterectomies in premenopausal women, hot conization of the cervix was performed prior to the scrub with an iodophore. No preoperative antibiotics were used in this series. The postoperative febrile morbidity rate was 4.3 per cent and the average stay was 4.5 days. These results are compared with those of three other groups: (1) patients who received a three-dose parenteral prophylactic antibiotic course with the first dose two hours prior to surgery had a febrile morbidity rate of 8.6 per cent. (2) In patients who had prophylactic antibiotics for five days with the first dose given intraoperatively, the febrile morbidity rate was 10.1 per cent. (3) The febrile morbidity rate in the group with no antibiotic prophylaxis or hot conization was 49.1 per cent. Laboratory and clinical data suggest that preoperative conization may be effective in the reduction of postoperative febrile morbidity.

Cervical conization: when is uterine dilatation and curettage also indicated?

Although the primary goal of cervical cone biopsy is treatment of cervical intraepithelial neoplasia, conization plus uterine dilatation and curettage is usually considered as a single, standard procedure. We reviewed 128 cone biopsies (114 of these procedures included dilatation and curettage) over a 3-year period to see whether dilatation and curettage was necessary as an accompaniment to conization. The mean age for all patients was 32.8 years, and 6.25% (eight patients) had a history of abnormal uterine bleeding. There was no evidence of endometrial abnormality in any of the 114 dilatation and curettage specimens. These findings suggest that dilatation and curettage is not warranted as a routine adjunct to cone biopsy. We believe more precise criteria for combining dilatation and curettage with conization are required, and these include: patients in the peri- or postmenopausal period, suspected intrauterine abnormalities, and the presence of abnormal glandular cells in a cytologic sample. With the use of these guidelines, only 18 patients (14%) would have required dilatation and curettage.

A comparison between laser excisional conization and laser vaporization for the treatment of cervical intraepithelial neoplasia.

One hundred twenty patients with cervical intraepithelial neoplasia who were treated by laser excisional conization were compared with a group of 100 women who had similar diagnoses and were treated by laser vaporization. Every operation in the series was performed in the outpatient surgical unit or in the office. In two thirds of the cases the procedures were carried out with the patients under local anesthesia. The parameters studied included time required to perform the procedure, immediate and delayed bleeding, postlaser stenosis, healing time, patient discomfort, persistence or recurrence of disease, and risk of invasion. The results of this study revealed few disadvantages to performing a laser excisional procedure. Immediate and delayed complications were less frequent with laser excisional conization. The time required to perform an excisional conization was on the average only 4 minutes longer than that for a vaporization. Most significantly, the laser excisional cone provides a large and excellent specimen for the pathologist to review.

Outpatient excisional management of cervical intraepithelial neoplasia. A prospective, randomized comparison between loop diathermy excision and laser excisional conization.

OBJECTIVE: The purpose of our study was to compare loop diathermy excision and laser excisional conization with respect to treatment time, reliability, effectiveness, and safety. STUDY DESIGN: Three hundred women with cervical intraepithelial neoplasia attending our colposcopy clinic were randomized to treatment with either loop diathermy excision (group 1, n = 150) or carbon dioxide laser excisional conization (group 2, n = 150), both performed with local anesthesia on an outpatient basis. Student's t or Mann-Whitney test were used to compare continuous data; the chi 2 test was used for categoric data. RESULTS: The mean age, parity, histologic features, depth of excision, and occurrence of residual or recurrent disease were similar; however, the mean time required to complete treatment and hemostasis (2.5 +/- 3.6 vs 24.2 +/- 11.8 min), patient discomfort, blood loss (2.77 +/- 3.76 vs 27.15 +/- 17.51 ml; p < 0.001), and considerable thermal artifact affecting histologic interpretation of excision margins (5 cases vs 25 cases; p < 0.01) were significantly less in group 1 than in group 2. CONCLUSION: In our experience outpatient loop diathermy excision is an equally effective, quicker, safer, and more reliable excisional technique than laser excisional conization.

Diagnostic and therapeutic efficacy of cervical conization.

Cervical conization was perfromed on 756 patients at the University of Kentucky Medical Center from July 1, 1964, to January 1, 1973. Sixty-six patients were pregnant at the time of conization. Eighty-six per cent of patients with cytologic findings of carcinoma in situ had histologic verification of carcinoma in situ or severe dysplasia, and there was absolute correlation between cytology and histology in 75 per cent of patients will occult invasive cancer. Cervical biopsies without colposcopic direction predicted either severe dysplasia or carcinoma in situ in 77 per cent of cases but were accurate in only seven of 24 patients with occult invasive cancer. Carcinoma in situ was present in 30 per cent of hysterectomy specimens following conization but recurred in only seven per cent of patients followed without hysterectomy. Recurrent carcinoma in situ following hysterectomy was more common in patients with residual intraepithelial cancer in the uterus but was independent of the size of the vaginal cuff removed. Major postconization complications requiring hospitalization occurred in 3.4 per cent of nonpregnant patients and in 7.5 per cent of pregnant patients.

[Removal of HPV infection of the portio vaginalis by laser therapy of scalpel conization].

Between May 1988 and December 1990, 855 patients were submitted to HPV-hybridisation. HPV 16/18 (10.4%) was detected more frequently (p = 0.0024) than HPV 31/33/35 (6.1%) and was more often associated with cervical intraepithelial neoplasia--CIN--III degrees (p = 0.0014). 42 patients with CIN were examined after treatment with cold-knife conization. PAP-smear, colposcopy and HPV-hybridisation were performed. None of the patients showed signs of CIN after treatment. Only one patient showed an HPV persistence. In three of 7 patients treated with laser conization and four of 12 patients treated with laser vaporization, examination after treatment showed signs of CIN. In 6 cases, an HPV persistence was detected. With regard to results of other authors, cold-knife conization is the most effective treatment of HPV infection of the cervix uteri.

Diagnostic conization of the cervix: review of 460 consecutive cases.

During a five-year period, 460 patients underwent cervical conization on the Gynecology Service at Memorial Hospital. The pertinent medical history of the 393 patients was reviewed as it related to the diagnosis of cervical intraepithelial neoplasia. All patients had repeat Papanicolaou smears and 94.4% had complete colposcopic examination using standard colposcopic procedures, endocervical curettage, and directed biopsies. For the purpose of this review, patients were separated into seven groups according to the primary and most significant indication for conization. The indications for the procedure and the histopathologic findings are discussed for each category. The usefulness of conization in the authors' institution varied according to the indication for which it was carried out. In this series of 393 patients, 18 patients (4.7%) initially diagnosed to have only intraepithelial disease, were found to have invasive carcinoma.

Colposcopy or cervical conization? An economic comparison.

Costs of colposcopic evaluation of patients with abnormal Papanicolaou smears versus evaluation by conization are compared. The average colposcopic evaluation costs $106, and the average conization costs $923.70. Additional savings ensue if a colposcopic diagnosis, rather than conization of the cervix, precedes a definitive hysterectomy. All criteria for an adequate colposcopic examination and tissue diagnosis must be met to make this comparison.

Reliability of cytological follow-up after conization of the cervix; a comparison of three surgical techniques.

A retrospective analysis was made of 154 consecutive conizations between 1974 and 1982. Three surgical methods were compared: (A) Sturmdorf sutures; (B) interrupted vertical sutures; and (C) an 'open' method using only cauterization and no additional stitches. The mean blood loss during conization was not reduced by ligation of descending branches of the uterine arteries. Post-conization haemorrhage occurred in only 3% and did not differ between the three groups. Cervical smears with only ectocervical squamous epithelium or too little material to allow diagnosis were considered inadequate. Unreliable follow-up was defined as inadequacy of more than 25% of a patient's smears. Thirty per cent of all follow-up smears were inadequate (group A 33%; B 41%; C 16%). In 46% of the patients, cytological follow-up was unreliable (group A 48%; B 61%; C 18%) and additional measures such as dilatation of the cervix, endocervical curettage, or hysterectomy were required. The differences between group C and the other two groups were statistically significant (P less than 0.01; chi 2 test).
