Advances in sterilization equipment.

From the array of sterilization procedures that are safe, simple and effective, the service provider must select procedures that fit his or her logistical criteria, which include the cost and maintenance of equipment, availability of supplies, and training of the requisite personnel. In this paper, these criteria are discussed for each of the various sterilization procedures. Information about female sterilization equipment for conventional postpartum laparotomy, minilaparotomy, colpotomy, laparoscopy, and culdoscopy is presented, together with facts about the related tubal occlusion techniques. The standard ligation techniques for male sterilization are compared with the newer electrocoagulation and thermocoagulation methods. A variety of methods for both female and male sterilization that are in the research stage are also mentioned. It is concluded that, from a programmatic point of view, vasectomy and postpartum ligation via laparotomy are the optimal sterilization procedures. For women who have not recently been pregnant, minilaparotomy with a standard tubal ligation technique is recommended, except in large teaching hospitals where laparoscopy can be performed efficiently.

Correlation between hysterosalpingography and pelvic endoscopy for the evaluation of tubal factor.

In this study of 132 infertile couples, findings with hysterosalpingography (HSG) were compared with those observed at subsequent culdoscopy or laparoscopy. Both procedures correctly revealed normal tubes in 29% of the subjects and identical abnormalities in 24%. A complete agreement between the two procedures was thus observed in 53% of women. Hysterosalpingography showed 5% false positive and 14% false negative findings. In the remaining cases the type of anomaly revealed by HSG was different from that found at laparoscopy. Peritubal adhesion was the pathologic process most commonly missed by HSG and diagnosed subsequently by endoscopy. Pelvic endoscopy also revealed endometriosis and other pelvic disease in a high proportion of women, whereas HSG exclusively detected all intrauterine lesions. Similar pregnancy rates resulted when HSG and endoscopy revealed normal organs. The significance of these findings is discussed.

[Male and female sterilization techniques: Summary of ANAES assessments (May 2005)].

OBJECTIVE: To summarize assessments carried out by ANAES on male and female sterilization techniques. The summary was requested by the French Health Directorate after the law authorizing sterilization as a means of contraception was passed. RESULTS (FEMALE STERILIZATION): (i) EFFICACY of tubal ligation, electrocoagulation, clips or rings: the annual pregnancy rate is 0-2% depending on the study, with no significant difference between techniques. No data were found on fimbriectomy. (ii) EFFICACY of a hysteroscopically placed micro-insert device: no pregnancies were observed in patients with bilateral tube obstruction diagnosed by hysterosalpingography at 3 or at 6 months after placement (placement rate: 87-89%). (iii) SAFETY of tubal ligation, electrocoagulation, clips or rings: (a) By approach: There was no difference in the incidence of major complications between laparoscopy and minilaparotomy but there were significantly fewer minor complications with laparoscopy than with minilaparotomy. There were significantly more major complications with culdoscopy than with minilaparotomy and significantly more minor complications than with laparoscopy. (b) By operative technique: major and minor complications were significantly more common with the Pomeroy technique than with electrocoagulation; the difference could be due to the approach used. No data were available on fimbriectomy. (iv) SAFETY of a hysteroscopically placed micro-insert device: there were 11 cases of myometrial or tubal perforation among 734 patients (with device displacement into the peritoneal cavity in 3 cases). RESULTS (MALE STERILIZATION): (i) EFFICACY: efficacy varied from 84% to 100% depending on the approach and the mode of vas deferens obstruction. There was no significant difference in efficacy according to approach (transcutaneous or scrotal). However, no conclusion could be drawn on the comparative efficacy of the occlusion techniques used from published data. (ii) SAFETY: the rate of postoperative complications was low, below 10% in most series. Complications were benign and only rarely necessitated surgical revision. CONCLUSION: The advantage of sterilization methods is that they lack any permanent contraindication. They should be presented as being generally irreversible. Fimbriectomy is not recommended for female sterilization. Laparoscopy is the preferred approach. Sterilization by hysteroscopic placement of a micro-insert device should be restricted to cases presenting a risk on laparoscopy; the technique should be re-assessed in 2006. The two approaches used for male sterilization are technically similar and do not seem to differ in efficacy. The Public Health Code states that "Fallopian tube or deferens duct ligation for contraceptive purposes is not allowed in minors" and that ligation "cannot be performed unless the adult involved has given his/her informed and motivated consent, expressed after taking into consideration clear, complete information on the consequences of the procedure". A waiting period of four months must follow the moment the decision to sterilize is taken and consent is given. An informed consent form must be signed. Sterilization in young or nulliparous women should be proposed with the greatest prudence and with many reservations.

Scintigraphic evidence of adrenal cortical dysfunction in the polycystic ovary syndrome.

The polycystic ovary syndrome (PCO) is frequently associated with elevated plasma levels of adrenal androgens and/or abnormal adrenal androgen responses to hormonal stimulation and suppression. Because of the overlap in the output of hormones between the adrenal glands and the ovaries, we measured adrenal iodocholesterol accumulation as an index of adrenocortical function in 11 women with PCO confirmed by laparoscopy or culdoscopy. All patients had normal dexamethasone suppression of plasma cortisol or urinary 17-hydroxycorticosteroid excretion. 6 beta-[131I]Iodomethylnorcholesterol (NP-59) adrenal scintiscans showed bilateral and excessive adrenal cortical uptake in PCO patients [0.46 +/- 0.08% (+/- SE) of the administered dose compared to 0.21 +/- 0.01% in a group of normal women; P less than 0.05]. The elevation of adrenal cortical NP-59 uptake in PCO was quantitatively similar to that in women with ACTH-dependent Cushing's syndrome (0.64 +/- 0.11%; P greater than 0.1). These data support the presence of abnormal adrenal cortical function in patients with PCO. The adrenal dysfunction of PCO most likely represents abnormal control of adrenal androgen production/secretion.

Nonsurgical collection of embryos in Shiba goats.

A method of nonsurgical embryo collection in the Shiba goat, a native Japanese miniature goat breeding nonseasonally, was developed. The apparatus used for flushing the uterus was made on the model of the two-way catheter for cows. Embryo collection was performed on days 5 to 7 in 37 females superovulated with PMSG and hCG and resulted in successful recovery of 69 embryos in 19 females (51.4%). The average number of embryos collected from each successful female was 3.6. The recovery rate of embryos calculated on the basis of the number of embryos recovered and corpora lutea observed by culdoscopy in 15 successful females was 89.5%. This nonsurgical method seem to be efficient enough for collecting morulae and blastocysts in Shiba goats.

Hysteroscopy.

Hysteroscopy is a "new" endoscopic approach for the gynecologist. The development and refinement of the sophisticated fiberoptic light system can illuminate the darkness of the uterine cavity. Polyps can be differentiated from submucous myomas; intrauterine adhesions can be accurately "mapped" and classified, with synechiae lysed under direct vision; endometrial carcinoma can be diagnosed and possibly staged; embedded intrauterine devices can be identified and dislodged; the wastebasket diagnosis of "dysfunctional uterine bleeding" can be cleaned up; submucosal myomas and uterine septa can be resected; and successful transuterine sterilization may become a reality. If culdoscopy is menopausal and laparoscopy in its reproductive years, hysteroscopy is certainly in its infancy.

Acute abdominal pain in gynaecology.

Fifty female patients with acute abdominal pain were studied. High risk factors helping in clinical diagnosis were evaluated and 7(14%) cases with clear cut surgical indications were immediately operated on while 43 (86%) were kept under active observation. In doubtful cases, culdoscopy and diagnostic laparoscopy were found to be helpful in confirming the diagnosis and another 26% were operated later on. The delay in surgery did not increase the morbidity and mortality and only one patient (2%) underwent unnecessary laparotomy. Hence, it was concluded that active observation in cases of acute abdominal pain of doubtful origin is a safe and effective approach.

Psychosexual attitudes in the female following sterilization.

This study represents a three year follow-up, summarizing the psychosexual attitudes of 120 patients who were sterilized with tubal occlusion by one of three methods: culdoscopy, laparoscopy or postpartum laparotomy. The results indicate that most patients had a favorable impression of the procedure with little significant change in their sexual habits. Eight per cent of patients expressed regret at not being able to have more children. The frequency of coitus remained largely unchanged.

Gynecologic endoscopy in infertility.

Pelvic endoscopic techniques enable the physician to make accurate diagnoses, to treat specific pelvic disorders, and to gather information for research. This article focuses on these techniques as they apply to the management of infertile patients. Included for discussion are diagnostic and therapeutic laparoscopy and hysteroscopy, culdoscopy, and salpingoscopy.

Laparoscopy.

In the last five years, laparoscopy has become increasingly popular in North America. The procedure has been mainly embraced by the gynecologist and its use in this field has largely supplanted culdoscopy. Other specialties, nevertheless, have been slower in recognizing its value.The procedure has wide applications in gynecology. In pediatrics, laparoscopy proves useful in elucidation of amenorrhea, intersex and precocious puberty. In general surgery, laparoscopy has been recognized as a useful tool in the patient with multiple trauma, and in establishing the diagnosis of many intra-abdominal conditions.Numerous perlaparoscopic operative procedures which include biopsies and tubal sterilizations may be carried out by an experienced operator. Complications associated with the procedure are few, but may be severe. These can be avoided by careful adherence to proper technique.

Culdoscopic ligation as an outpatient procedure.

The increasing demand for abortion and sexual sterilization has caused the need to perform such operations on an outpatient basis. The University Department of Obstetrics and Gynaecology, Singapore, started a prospective study of culdoscopic ligation as an outpatient procedure in November, 1972. To date, over 600 operations have been performed. Analysis of the first 405 cases showed a low complication rate of 2.4 per cent. This study showed that culdoscopic ligation performed in the hospital outpatient is safe and feasible.
