Intramural Myomectomy Using a Combination of Hysteroscopy and Laparoscopy

Thanks to advances in hysteroscopic surgery and improvements in instrumentation, hysteroscopy can now be performed for intramural myomas. Twelve women with submucous or intramural myomas with a diameter ranging from 3.5 to 5.8 cm received preoperative preparation with 5 months of gonadotropin-releasing hormone analogs. The uterine cavity was distended with sorbitol-mannitol solution infused by an electronic pump. Hysteroscopic resection was performed with a 26F resectoscope and electrosurgical monopolar unit under laparoscopic control in all patients. Four women required a second procedure to complete the resection of myoma. No major complications occurred.

Risks of Virus Transmission During Diagnostic Hysteroscopy

The high frequency of asymptomatic carriers of viral infections represents a major risk for transmission. Viral agents can be transmitted through blood or biologic fluids during diagnostic hysteroscopy. Routine disinfection methods to clean hysteroscopes cannot be considered adequate to prevent transmission. Hepatitis C and B viruses require 1-hour sterilization in glutaric aldehyde or gas sterilization (ethylene oxide) to be decontaminated. Human immunodeficiency virus decontamination of instruments is easier and safer. Blood test screening of patients positive for hepatitis B and C should be performed in all candidates for endoscopic gynecologic procedures to avoid the possibility of virus transmission.

[Hysteroscopic evaluation of the endometrium in 63 postmenopausal patients treated with tamoxifen for breast cancer].

This retrospective analysis intends to evaluate by histeroscopy the endometrial findings in a group of 63 patients in post-menopausal treated with tamoxifen for breast cancer. Our patients assumed tamoxifen for a different period between 6 and 120 months. Patients have been divided in two groups: I) patients undergoing hysteroscopy because of some clinical symptoms; II) patients who undergoing hysteroscopy as a routine examination. The most important observation of this work is the correlation between the presence of negative endometrium and low risk hyperplasia (LRH) associated to: symptomatology and duration of therapy. In the group of asymptomatic patients the LRH is found only after 3 years of treatment, while in the group of symptomatic patients, LRH is present within the first two years of treatment; beyond this period high risk hyperplasia (HRH) and endometrial carcinoma have been diagnosed. We also observed a higher incidence of endometrial polyps in this population than among the non treated group and among the symptomatic patients. From these data we conclude that hysteroscopy follow-up has to be performed in the group of patients treated with tamoxifen and that it would be necessary to have a hysteroscopy before the beginning of therapy and that this one has to be repeated once a year through the treatment. Obviously the symptomatic patients have to undergo hysteroscopy as soon as possible as a higher incidence of HRH and endometrial carcinoma has been detected in this group of patients.

Can hysteroscopic evaluation of endometrial carcinoma influence therapeutic treatment?

235 cases of primary endometrial adenocarcinoma (AC) (age range, 37-94; mean age, 61 years) were collected during the period 1980-1992. Hysteroscopic examination of both the endometrial cavity and the cervical canal was performed in every patient prior to hysterectomy, and evaluations of cancer extension in the endometrium (focal: 97 pts; partial: 82 pts; massive: 47 pts; unevaluable: 9 pts) and of endocervical involvement (positive: 45 pts) were compared to the histological findings and survival rates. The chi 2 test was used for statistical analysis, and statistical significance was considered where the p value was < 0.05. Endometrial extension was poorly related to the depth of myometrial invasion (M1 = depth of invasion to < 1/2 myometrium, M2 = invasion to > 1/2 myometrium): focal AC: M1 57.8%, M2 42.2%; partial AC: M1 40.2%, M2 59.8%; massive AC: M1 51.1%, M2 48.9%; (p = 0.5). Endocervical involvement was unrelated to endometrial extension. No correlation was found between AC histological grade (G1-G3) and entity of endometrial extension, whereas grade showed a significant correlation with myometrial invasion (G1 M1: 69.1%; G3 M1: 41.0%; p = 0.002) and survival rates (G1 90.4%, G2 88.5%, G3 69.4%; p = 0.01). Five-year survival figures showed no evident correlation with cancer extension (focal AC: 86.5%; partial AC: 87.8%; massive AC: 86.3%; p = 0.9) whereas myometrial invasion showed a statistical significance (M1: 91.4%, M2: 79.7%; p = 0.03). Three patterns of invasion were defined: pushing (P), infiltrative (I) and diffuse (D) isolated cells. There were significant differences between the various growth patterns and survival rates (P 90.7%; I 84.3%; D 45.4%; p = 0.0001). False negative rate of the hysteroscopic diagnosis of cervical involvement was 7.9% (18 cases); however, in 6 of these cases only deep cervical invasion was found.

GnRH agonist analogs and hysteroscopic resection of myomas.

OBJECTIVES: The purpose of this study was to evaluate the effects of pretreatment with GnRH analogs and hysteroscopic resection of submucous myomas previously deemed to be contraindicated for this approach. METHODS: Twenty-five patients were included in this study. Patients were assessed by ultrasonography and diagnostic hysteroscopy. They were treated with depot GnRH analogs for 3 months and then scheduled for hysteroscopic surgery. RESULTS: After GnRH therapy the diameter was 61 +/- 10% of the initial diameter. In one patient, therapy was almost ineffective. Hysteroscopic surgery was possible in all 25 patients. Seven patients presented an intramural myoma that was not possible to remove entirely during the first attempt. After dessication and 2 supplementary months of GnRH analog therapy, a second surgical attempt was successful in complete removal of the tumor in all except one case. In one patient hysterectomy 15 days after hysteroscopic surgery was necessary for incoercible bleeding due to a deep adenomiosis. CONCLUSIONS: A combined medical and surgical approach seems to reduce the limit of hysteroscopic surgery and avoid open myomectomy or hysterectomy in a well selected group of patients.

Levo-norgestrel-nova-T and precancerous lesions of the endometrium.

The authors report the preliminary data on the topical treatment of endometrial hyperplasia by an intrauterine device releasing Levo-norgestrel (LNG-Nova-T), in a series of 31 patients. The patients examined so far by endometrial biopsies performed at predetermined intervals showed a complete histological regression of the hyperplasia, regardless of its pattern.

Pre-neoplastic lesions of vulvar cancer.

The monitoring of potentially neoplastic lesions is based on the determination of the histopathologic characteristics of the lesion, which is done either by large surgical resection of the lesions "in toto" or by biopsy of the lesion. Chronic vulvar dystrophy may develop into carcinoma, the supposed likelihood varying according to the various Authors. The lesion which is histologically defined as atypical keratoacanthoma is the most frequent precursor of carcinoma. Most Authors agree in believing that lichen scleroatrophic does not often develop into carcinoma. It is, nevertheless, the most frequent precursor of leukoplakia which is, on the other hand, a risk lesion. However, any chronic vulvar irritation may increase the risk of cancer and must therefore be carefully monitored by multiple biopsies to be examined at regular intervals.

Chronic prostato-vesiculitis and sperm-cell mobility in male infertility.

The purpose of this research has been to value the importance of chronic inflammation of the prostatovesicular apparatus in sterile patients. The authors wish to underline the high incidence of chronic inflammation if this apparatus in such patients, the low incidence of bacterial forms and the high frequence of association with bradycinesia. The therapy of such forms gives excellent results.
