[First abdominal access in gynecological laparoscopy: which method to utilize?].

The choice of the technique to enter the peritoneal cavity, during a laparoscopy, depends on a lot of variables which hinder a standardized method and, actually, it appears impossible to show, with certainty, the best method to choose for the first abdominal access in gynecological laparoscopy. The preference for one or another technique depends on the operator experience, school and speciality of the surgeon, laparoscopical upgrading and the work environment; many surgical techniques are not yet used due the limits and fears of some surgeons to change the preference in first access approaching and for the lack of operating versatility by a method or another one. A review of the scientific literature, underlines that the major problems during the first laparoscopical abdominal access are two, vascular and intestinal and their percentage is variable. In this paper we describe the large range of methods for open and closed laparoscopy and for direct access, that permit to perform a first abdominal laparoscopical access, and their major possible problems.

Comparison of sequential combined spinal-epidural anesthesia and spinal anesthesia for cesarean section.

AIM: The aim of our study was to prove that by using sequential combined spinal-epidural (CSE) anesthesia it is possible to overcome the limits connected to the use of spinal anesthesia (SA) alone for elective cesarean section. METHODS: We examined 100 women submitted to cesarean section; SA was administered to 50 patients and sequential CSE technique to the other 50. In every woman before execution of the anesthesia we infused 500 mL of a plasma expander and a previous administration of 5 mg of ephedrine. The CSE was executed at the L1-L2 intervertebral space, administering in spinal anesthesia 5 mg of levobupivacaine with 5 _g of sufentanil, and in peridural anesthesia 10-12 mL of levobupivacaine 0.25% according to the patient's height. The peridural catheter for postoperative analgesia was then positioned. In the group of women submitted only to SA, 7.5-8 mg of levobupivacaine was injected, according to the patient's height, in the L1-L2 intervertebral space, with 5 _g of sufentanil. We considered the following adverse effects: hypotension; bradycardia; vomiting; intraoperative discomfort and motor block. RESULTS: The results obtained showed that, with a P < or = 0.05, the incidence of motor block (P < 0.001), discomfort (P < 0.001) and hypotension (P = 0.021) in the SA group is greater than in the CSE group. The difference in the incidence of vomiting (P = 0.147) and bradycardia (P = 0.067) between the 2 groups is not statistically significant. CONCLUSIONS: In our opinion sequential CSE can be considered an important step forward in the regional anesthesia used for elective cesarean section.

[Urinary incontinence in postmenopausal period: clinical and pharmacological treatments].

Urinary incontinence is a common clinical problem in female sex and occurs especially in postmenopausal women; this disease, that represents an economical problem for society, begins in young age, arises in middle age and increases in women more than 65 years old. Studies carried out on etiological factors involved in urinary incontinence show that estrogens enhance the trophism and vascularization of the muscular and fascial support of the pelvic floor, the growth of fibroblasts and the collagen metabolism in the superficial fascia in postmenopausal women. The postmenopausal estrogenic deficit could be related to many urogenital problems, but many researches performed on the effects of estrogens in urogenital postmenopausal homeostasis and of hormonal replacement therapy in postmenopausal incontinent women, did not show conclusive findings; for this reason, even if many authors attributed to menopause a role of major risk factor for incontinence, a direct correlation has never been confirmed. The treatment of postmenopausal female incontinence may be clinical and pharmacological, and includes a first step therapy (bladder training, biofeedback techniques, electrical pelvic floor stimulation) and a second step therapy (pharmacological therapy, bladder devices and surgical operations). In this review the clinical and pharmacological treatments, their efficacy and their application in incontinent postmenopausal women are described.

[Incidence of ectopic pregnancy at the 1st Clinic of Obstetrics and Gynecology of Bari during the past 10 years. Clinico-statistical considerations].

The Authors, in the period 1979-1988, discovered 175 ectopic pregnancies out of a total of 16.641 pregnancies: a rate of incidence of 1 in 95 (1.05%); 28 patients were fitted with an IUD. In accordance with published data, they recognize an increase in the incidence of ectopic pregnancies and emphasize the importance of a precocious clinical diagnostic, to reconcile timeliness of operation with the need of conservative surgery, the indication for which should take into account many factors (the age, the general condition, the parity, the wish for a pregnancy, the state and condition of the tube on each side) since it seems to predispose to recurrent ectopic pregnancies. They indicate the negative effects on the tube for patients fitted with an IUD.

[A case of primary ovarian pregnancy in an IUD-wearing patient].

A case of primary ovarian pregnancy in a patient fitted with an IUD is reported. Anatomic, pathological, clinical, etiological and therapeutical aspects of ovarian pregnancy are discussed with reference to published data. The case study presented in this paper shows the characteristics aspects of this pathology of pregnancy: the patient is a multipara, fitted with an IUD; clinical diagnosis was intraoperatively and adnexectomy was chosen as the most appropriate treatment. Anatomic and pathological tests were used to confirm the diagnosis of ovarian pregnancy.

[AIH and AID. Review of the literature: results and observations].

The literature on homologous artificial insemination and artificial insemination by donor is reviewed. In AIH the importance of the seminal factor and the influence of the induced superovulation are taken into account in determining the success of insemination. The important factors in AIH are: the type of sperm used (fresh or frozen), the characteristics of the female recipient, the method of insemination and its timing in relation to superovulation, and unwillingness to continue therapy. In line with other studies, it is emphasised that the factors involved in insemination must be standardised and defined according to recognised statistical principles in order to allow a meaningful comparison of data reported in the literature.

Valuation of some markers in the malignant neoplastic pathology of the female genital tract.

The Authors studied the presence of some markers in different gynaecological tumours, by radioimmunoassay. Beta-HCG, 1-alfa-FP, CA 125, GICA and TPA were assayed in 76 patients. Eight of the patients were affected by CIN III, 38 presented a cervical carcinoma (10 at stage I, 14 at stage II, 10 at stage III, 4 at stage IV); 14 patients had an endometrial adenocarcinoma (3 at stage I, 7 at stage II, 2 at stage III and II at stage IV); 12 cases consisted of an ovarian carcinoma with 2 patients at stage I, 5 at stage II and 5 at stage III; 2 patients had a peritoneal diffusion, whereas two women presented a vulvar carcinoma; the control group was formed by 10 patients with no malignant or benign pathology. The results show that tumoral markers, studied in the blood of patients affected by malignant gynaecological tumours, represent a great advantage in the evaluation of both the response to the therapy and of an eventual remission or tumoral recurrence.

Chemotherapy with CDDP.

The Authors report the results obtained in 30 patients affected by ovarian carcinoma and treated with chemotherapy using the parenteral route in 27 cases and the intraperitoneal one in 3 women. Parenteral chemotherapy following surgical staging and extensive tumour removal with the last residual tumour, consisted of a therapeutic scheme of mono- and poli-chemotherapy. The doses of cisplatin (CDDP) in mono-chemotherapy were correlated to the intensive anatomical-radiological-surgical staging. The patients treated with poli-chemotherapy underwent cycles with CDDP + alkylating agents. Moreover, 3 of the patients received low doses of cisplatin by intraperitoneal administration. In 27 cases pre- and post-therapy enzymuria was evaluated: it represents, in fact, the most reliable laboratory test to discover an acute tubulo-toxicity and is able to reveal chronic tubular damage. Our results demonstrate that a suitable nephrologic monitoring of the patients allows a more accurate use of the cisplatin with a better cost-benefit relation.

Role of radiotherapy in the management of cervical carcinoma.

Different therapy schemes related with the stage of tumours are reported, after general considerations on the topic. We have evaluated various criteria for the choice of methods, pointing out the complications of therapy. Lithium-carbonate action during radiation therapy has been studied, valuing the positive effect on leukopoiesis and the consequent better clinical conditions of the patients in course of treatment. In this study we report our experience with regard to 21 patients affected by cervical neoplasia, histologically diagnosed. The stages of neoplasia in the 21 patients were so distributed: 10 at stage I B, 8 at stage II A, 3 at stage II B. Treatment consisted of three therapeutical techniques: 1) application of radium in the cervical canal and in the vaginal fornices; 2) surgical procedure; 3) application of radium against the vaginal vault. In agreement with other author's results, the histological exam of the surgical specimen confirmed in different cases the complete absence of neoplastic aspects following the pre-operative radiotherapy. Although our experience is limited, we hold that radio-surgical "sandwich" treatment of cervical carcinoma may represent an excellent therapy in young women and in patients with associated systemic diseases. The follow-up of the 21 patients has excluded up to this day any neoplasia. In this program pre-operative intracavitary radiotherapy is a primary step allowing, in the majority of the cases, the reduction of surgical radicality. In so doing, effective therapeutical results associated with a better quality of life are obtained.

Virus in gynaecological oncology.

We measured the antibody presence of eventual viral infections (Parotiditis, Cytomegalovirus, Herpes Simplex and Hepatitis B) in 51 patients affected by malignant gynaecological tumours. Ninety five women composing the control group not affected by any pathology, underwent the same tests. Even if research has utilized various indirect methods for the antibody dosage of each viral infection, we have not confirmed other Authors' reports. It might be referable to the limited number of cases in our study up to date. In order to make a comparison among different reports we look forward to a uniformity of various laboratory methods. Reliable results will be obtained only by increasing the number of clinical cases and by utilizing the method of determination of viral genome in tumoral cells. The technique is the only reliable among different methods for determining a previous viral infection.
