Changes in menstrual blood loss after four methods of female tubal sterilization

Identifying risk factors in explaining women's anaemia in limited resource areas: evidence from West Bengal of India and Bangladesh

Background

Anaemia among women is a public health problem with associated adverse outcomes for mother and child. This study investigates the determinants of women’s anaemia in two Bengals; West Bengal (a province of India) and Bangladesh. These two spaces are inhabitated by Bengali speaking population since historic past. The study argues that open defecation, contraceptive method use and food consumption patterns are playing crucial role in explaining anaemia.

Methods

Using non-pregnant women belonging to different religious groups, we analyzed a total of 21,032 women aged 15–49 from the nationally representative cross-sectional surveys, i.e., Bangladesh Demographic Health Survey (BDHS-VI, 2011) and National Family Health Survey (NFHS round 4, 2015–16). We performed spatial, bivariate and logistic regression analyses to unfold the important risk factors of anaemia in two Bengals.

Results

The prevalence of anaemia was 64% in West Bengal and 41% in Bangladesh. The significant risk factors explaining anaemia were use of sterilization, vegetarian diet and open defecation. Further, women who used groundwater (tube well or well) for drinking suffered more from anaemia. Also, younger women, poor, less educated and having more children were highly likely to be anaemic. The study also indicates that those who frequently consumed non-vegetarian items and fruits in West Bengal and experienced household food security in Bangladesh were less prone to be anaemic. Hindus of West Bengal, followed by Muslims of that state and then Hindus of Bangladesh were at the higher risk of anaemia compared to Muslims of Bangladesh, indicating the stronger role of space over religion in addressing anaemia. Unlike West Bengal, Bangladesh observed distinct regional differences in women's anaemia.

Conclusions

Propagating the choices of contraception mainly Pill/ injection/IUDs and making the availability of iron rich food along with a favourable community environment in terms of safe drinking water and improved sanitation besides better education and economic condition can help to tackle anaemia in limited-resource areas.

Impact of Curcumin on Ovarian Reserve After Tubal Ligation: an Experimental Study

The aim of this study was to evaluate the effects of tubal ligation (TL) via modified Pomeroy method on ovarian reserve and to determine the role of curcumin (Curcuma longa [Indian saffron]) against ovarian reserve decrement after TL. Forty-eight albino Wistar rats were randomly divided into four groups: (1) Control group: a sham operation was performed (n = 12), (2) Tubal ligation group: TL was performed (n = 12), (3) TL+DMSO group: 1 mL/day dimethyl sulfoxide was used for 50 days after TL, (4) TL+Curc group: 100 mg/kg/day curcumin dissolved in DMSO was administrated for 50 days after TL. Pre-operatively and on post-operative day 50, blood samples were collected for AMH evaluation, and oophorectomy was performed for histological and immunohistochemical examinations of ovaries in all groups. No difference in the basal AMH levels was found among the groups (p = 0.249). Compared to the basal, AMH levels were lower in the control, TL, and TL+DMSO groups (p = 0.003, p = 0.004, and p < 0.001, respectively) but not different in the TL+Curc group (p = 0.503) on post-operative day 50. No significant differences in the number of primary, preantral, antral, atretic follicles, and corpus luteum among the groups (p > 0.05) were found. The percentage of granulosa cells stained for caspase-3 in antral follicles and the corpus luteum was higher in the TL+Curc group than in the control and TL groups ([antral follicles; p < 0.01 for both groups], [corpus leteum; p = 0.009 and 0.002 for the control and TL groups, respectively]). It seems that TL does not decrease ovarian reserve and curcumin might have a positive effect on ovarian reserve in the setting of TL.

Techniques for the interruption of tubal patency for female sterilisation

BACKGROUND

This is an update of a review that was first published in 2002. Female sterilisation is the most popular contraceptive method worldwide. Several techniques exist for interrupting the patency of fallopian tubes, including cutting and tying the tubes, damaging the tube using electric current, applying clips or silicone rubber rings, and blocking the tubes with chemicals or tubal inserts.

OBJECTIVES

To compare the different tubal occlusion techniques in terms of major and minor morbidity, failure rates (pregnancies), technical failures and difficulties, and women's and surgeons' satisfaction.

SEARCH METHODS

For the original review published in 2002 we searched MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL). For this 2015 update, we searched POPLINE, LILACS, PubMed and CENTRAL on 23 July 2015. We used the related articles feature of PubMed and searched reference lists of newly identified trials.

SELECTION CRITERIA

All randomized controlled trials (RCTs) comparing different techniques for tubal sterilisation, irrespective of the route of fallopian tube access or the method of anaesthesia.

DATA COLLECTION AND ANALYSIS

For the original review, two review authors independently selected studies, extracted data and assessed risk of bias. For this update, data extraction was performed by one author (TL) and checked by another (RK). We grouped trials according to the type of comparison evaluated. Results are reported as odds ratios (OR) or mean differences (MD) using fixed-effect methods, unless heterogeneity was high, in which case we used random-effects methods.

MAIN RESULTS

We included 19 RCTs involving 13,209 women. Most studies concerned interval sterilisation; three RCTs involving 1632 women, concerned postpartum sterilisation. Comparisons included tubal rings versus clips (six RCTs, 4232 women); partial salpingectomy versus electrocoagulation (three RCTs, 2019 women); tubal rings versus electrocoagulation (two RCTs, 599 women); partial salpingectomy versus clips (four RCTs, 3627 women); clips versus electrocoagulation (two RCTs, 206 women); and Hulka versus Filshie clips (two RCTs, 2326 women). RCTs of clips versus electrocoagulation contributed no data to the review.One year after sterilisation, failure rates were low (< 5/1000) for all methods.There were no deaths reported with any method, and major morbidity related to the occlusion technique was rare.Minor morbidity was higher with the tubal ring than the clip (Peto OR 2.15, 95% CI 1.22 to 3.78; participants = 842; studies = 2; I² = 0%; high-quality evidence), as were technical failures (Peto OR 3.93, 95% CI 2.43 to 6.35; participants = 3476; studies = 3; I² = 0%; high-quality evidence).Major morbidity was significantly higher with the modified Pomeroy technique than electrocoagulation (Peto OR 2.87, 95% CI 1.13 to 7.25; participants = 1905; studies = 2; I² = 0%; low-quality evidence), as was postoperative pain (Peto OR 3.85, 95% CI 2.91 to 5.10; participants = 1905; studies = 2; I² = 0%; moderate-quality evidence).When tubal rings were compared with electrocoagulation, postoperative pain was reported significantly more frequently for tubal rings (OR 3.40, 95% CI 1.17 to 9.84; participants = 596; studies = 2; I² = 87%; low-quality evidence).When partial salpingectomy was compared with clips, there were no major morbidity events in either group (participants = 2198, studies = 1). The frequency of minor morbidity was low and not significantly different between groups (Peto OR 7.39, 95% CI 0.46 to 119.01; participants = 193; studies = 1, low-quality evidence). Although technical failure occurred more frequently with clips (Peto OR 0.18, 95% CI 0.08 to 0.40; participants = 2198; studies = 1; moderate-quality evidence); operative time was shorter with clips than partial salpingectomy (MD 4.26 minutes, 95% CI 3.65 to 4.86; participants = 2223; studies = 2; I² = 0%; high-quality evidence).We found little evidence concerning women's or surgeon's satisfaction. No RCTs compared tubal microinserts (hysteroscopic sterilisation) or chemical inserts (quinacrine) to other methods.

AUTHORS' CONCLUSIONS

Tubal sterilisation by partial salpingectomy, electrocoagulation, or using clips or rings, is a safe and effective method of contraception. Failure rates at 12 months post-sterilisation and major morbidity are rare outcomes with any of these techniques. Minor complications and technical failures appear to be more common with rings than clips. Electrocoagulation may be associated with less postoperative pain than the modified Pomeroy or tubal ring methods. Further research should include RCTs (for effectiveness) and controlled observational studies (for adverse effects) on sterilisation by minimally-invasive methods, i.e. tubal inserts and quinacrine.

Techniques for the interruption of tubal patency for female sterilisation

BACKGROUND

Female sterilisation is the most popular contraceptive method worldwide. Several techniques are described in the literature, however only few of them are commonly used and properly evaluated.

OBJECTIVES

To compare the different tubal occlusion techniques in terms of major and minor morbidity, failure rates (pregnancies), technical failures and difficulties, and women's and surgeons' views.

SEARCH STRATEGY

Originally MEDLINE and The Cochrane Controlled Trials Register were searched. For the 2010 update, searches of Popline, Lilacs, Pubmed and The Cochrane Controlled Trials Register were performed. Reference lists of identified trials were searched.

SELECTION CRITERIA

All randomised controlled trials comparing different techniques for tubal sterilisation, regardless of the route of Fallopian tube access or the method of anaesthesia.

DATA COLLECTION AND ANALYSIS

Trials under consideration were evaluated for methodological quality and appropriateness for inclusion. Nine relevant studies were included and the results were stratified in five groups: tubal ring versus clip, modified Pomeroy versus electrocoagulation, tubal ring versus electrocoagulation, modified Pomeroy versus Filshie clip and Hulka versus Filshie clip. Results are reported as odds ratio for dichotomous outcomes and weighted mean differences for continuous outcomes.

MAIN RESULTS

Tubal ring versus clip: Minor morbidity was higher in the ring group (Peto OR 2.15; 95% CI 1.22, 3.78). Technical difficulties were found less frequent in the clip group ( Peto OR 3.87; 95% CI 1.90, 7.89). There was no difference in failure rates between the two groups (Peto OR 0.70; 95% CI 0.28, 1.76). Pomeroy versus electrocoagulation: Women undergoing modified Pomeroy technique had higher major morbidity than those with the electrocoagulation technique (Peto OR 2.87; 95% CI 1.13, 7.25). Postoperative pain was more frequent in the Pomeroy group (Peto OR 3.85; 95% CI 2.91, 5.10). Tubal ring versus electrocoagulation: Post operative pain was more frequently reported in the tubal ring group. No pregnancies were reported. Pomeroy versus Filshie clip: In the only trial comparing the two interventions only one pregnancy was reported in the Pomeroy group after follow-up for 24 months. No differences were found when comparing Hulka versus Filshie clip in the only study that compared these two devices.

AUTHORS' CONCLUSIONS

Electrocoagulation was associated with less morbidity including post-operative pain when compared with the modified Pomeroy and tubal ring methods, despite the risk of burns to the small bowel. The small sample size and the relative short period of follow-up in these studies limited the power to show clinical or statistical differences for rare outcomes such as failure rates. Aspects such as training, costs and maintenance of the equipment may be important factors in deciding which method to choose.

Hormonal and ovarian stromal blood supply changes after laparoscopic tubal sterilization: a prospective controlled study

OBJECTIVES

The purpose of this study is to determine if the effects of tubal sterilization (TS) by laparoscopy have any risk of a subsequent significant decrease in ovarian reserve and vascular support within the ovary by means of stromal artery Doppler study, and to compare the results with matched paired controls.

DESIGN

Between February 2002 and January 2005, 148 healthy volunteers were enrolled sequentially, 74 undergoing laparoscopic TS (study group) and 74 age-, parity-, body mass index-matched women were recruited as a control group. The main outcome measurements were blood levels of follicle-stimulating hormone (FSH), luteinizing hormone and E2, ovarian volume, number of antral follicles and Doppler study of ovarian stromal artery pulsatile index (PI) and maximum velocity (Vmax) on the third day of the cycle immediately before, and 1 and 12 months after the surgical intervention.

RESULTS

There were significant elevations in both serum FSH levels and PI values observed 1 month after TS, compared to the preoperative levels (p < .05), and also when compared to controls. However, there were no significant elevations at 12 months postoperation in both study and control groups. The other outcome measurements did not show any significant differences between the two groups.

CONCLUSIONS

Tubal sterilization by laparoscopic electrocoagulation does not cause any decrease in ovarian reserve or ovarian stromal blood supply, except an early postoperative increase in FSH and PI.

Examination of changes caused by tubal sterilization in ovarian hormone secretion and uterine and ovarian artery blood flow rates

OBJECTIVES

To examine the changes caused by tubal sterilization (TS) in ovarian hormone secretion and uterine and ovarian circulation.

DESIGN

Tubal sterilization was performed by minilaparotomy and laparoscopy methods in 36 women. Blood samples were taken for hormonal tests on Preoperative Day 3 (D3) of the menstrual cycle, on Postoperative Days 13-15 (periovulatory period) of the same cycle and on D3 in the 1st and 6th months post-TS. Uterine and ovarian artery blood flow rates of the women were measured on the same days as hormonal tests by transvaginal color Doppler ultrasonography (TVCDUSG). The control group was composed of 15 volunteers in the same age group who preferred the barrier method and who had the same TVCDUSG and hormonal analyses in the same periods.

RESULTS

There was a decrease in the uterine and ovarian artery pulsatility index (PI) measurements and an increase in serum luteinizing hormone (LH) and estradiol (E2) values during the periovulatory period as compared with preoperative and postoperative menstrual measurements in all groups. There was no difference between baseline uterine and ovarian artery PI and serum follicle-stimulating hormone, LH and E2 values and those measured on D3 of the menstrual cycle in the 1st and 6th months post-TS.

CONCLUSIONS

The 6-month postoperative follow-up of groups that had undergone different TS methods showed no difference in uterine or ovarian artery blood flow rates or ovarian hormone secretion in comparison with baseline values.

The Cochrane Controlled Trials Register has been searched. A search of the reference lists of identified trials was performed. An additional MEDLINE search was done using an Internet search service Pub Med.

SELECTION CRITERIA

All randomized controlled trials comparing different techniques for tubal sterilization, regardless of the way of entry in the abdominal cavity or the method of anesthesia.

DATA COLLECTION AND ANALYSIS

Trials under consideration were evaluated for methodological quality and appropriateness for inclusion. Nine relevant studies were included and the results were stratified in five groups: tubal ring versus clip, modified Pomeroy versus electrocoagulation, tubal ring versus electrocoagulation, modified Pomeroy versus Filshie clip and Hulka versus Filshie clip.

There was no difference in failure rates between the two groups (Peto OR 0.70; 95% CI 0.28, 1.76). Pomeroy versus electrocoagulation: Women undergoing modified Pomeroy technique had higher major morbidity than with electrocoagulation technique (Peto OR 2.87; 95% CI 1.13, 7.25). Postoperative pain was more frequent in the Pomeroy group (Peto OR 3.85; 95% CI 2.91, 5.10). Tubal ring versus electrocoagulation: Post operative pain was more frequently reported in the tubal ring group. No pregnancies were reported. Pomeroy versus Filshie clip: In the trial comparing the two interventions only one pregnancy was reported in the Pomeroy group after follow-up for 24 months. No differences were found when comparing Hulka versus Filshie clip in the only study that compared these two devices (Toplis 1988).

REVIEWER'S CONCLUSIONS

Electrocoagulation was associated with less morbidity when compared with tubal ring and other methods. However the risk of burns to the small bowel might be a serious criticism of the approach. The small sample size and the relative short period of follow-up in these studies limited the power to show clinical or statistical differences for rare outcomes such as failure rates. Aspects such as training, costs and maintenance of the equipment may be important factors in deciding which method to choose.

The changes in ovarian hormone levels and ovarian artery blood flow rate after laparoscopic tubal sterilization

OBJECTIVE

To investigate the changes in serum ovarian hormone levels and ovarian artery blood flow rate by Doppler ultrasonography following laparoscopic tubal sterilization.

METHODS

Laparoscopic tubal sterilization have been performed on 13 voluntary subjects between the sixth and eighth days of the menstrual cycle. Serum ovarian hormone levels and ovarian artery blood flow rate, by Doppler ultrasonography, were determined 3 days before the operation, on the post-operative third day and on the post-operative third month. The results of 10 participants who finished the follow-up period were analyzed.

RESULTS

There were no statistically significant changes in serum levels of ovarian hormones after laparoscopic tubal ligation. The end-diastolic blood flow in ovarian artery was found to be decreased following tubal sterilization (8.7+/-2.8 and 7.4+/-1.8m/sec, respectively, P>0.05), while resistivity index (RI) increased after the operation (0.7+/-0.1 and 0.8+/-0.03, respectively, P>0.05).

CONCLUSION

There was no change in ovarian hormone levels after laparoscopic tubal sterilization. There is slight but statistically non-significant decrease in ovarian artery blood flow rate following tubal sterilization, signifying a local increase in vascular resistance.

Female sterilization. Evidence

The literature review herein reveals substantial information regarding the safety, efficacy, short-term complications, long-term complications, and noncontraceptive benefits of sterilization. This information should be helpful for providers and potential sterilization candidates. The review also reveals areas where the data are unclear. Points to keep in mind during counseling include the following: The vast majority of women are satisfied with the decision to undergo sterilization. The fact that regret occurs underscores the importance of counseling and adequate individual deliberation before the procedure. In addition to the difficulty and expense associated with sterilization reversal, the woman should thoroughly understand the permanence of the procedure. Although failure is a rare event, it can occur many years after the procedure. Although evidence suggests that hysterectomy rates are higher in sterilized women aged less than 30 to 35 years, it is unlikely that there is a plausible biologic effect of sterilization on hysterectomy risk. An association between tubal sterilization and menstrual cycle changes does not seem valid for changes noted up to 2 years after the procedure. Data are unclear and inconsistent among studies observing women more than 2 years after the procedure. Evidence consistently shows that sterilization is associated with a reduced incidence of ovarian cancer and pelvic inflammatory diseases. Most studies show no effect or improvement of sexual satisfaction after sterilization. Complications during and postprocedure are rare. Sterilization provides no protection against the acquisition of sexually transmitted disease. Patients and their physicians should recognize that sterilized women may need more targeted preventive efforts for health screening and to reduce high-risk behavior than women who use other contraceptive methods. The surgeon's experience and the woman's preferences should govern the ultimate decision regarding the approach and occlusion method. Level II-2 evidence indicates comparable safety between interval laparoscopy and minilaparotomy. Data consistently show that in experienced trained hands, tubal sterilization is safe and highly effective regardless of the approach or occlusive method. Attention to the subtleties of technique seems to be most important in ensuring procedure safety and efficacy. Reanalysis of the CREST data shows that the cumulative failure rate of bipolar coagulation is comparable with the failure rate of unipolar coagulation if a substantial length of tube is adequately coagulated. The data discussed herein can be used to guide management decisions that may increase accessibility and reduce cost of the procedure. Low-resource settings and office settings have maintained an excellent safety record for this procedure through performance of sterilization under local anesthesia. The use of local anesthesia enables a change in procedure location from an inpatient operating room to a free-standing surgical clinic or adequately equipped office. Local anesthesia, with or without preoperative medication, is an excellent option associated with a lower complication risk, reduced cost, and shorter, easier recovery. The surgeon should have specific training in the effective use of local anesthetics, preoperative medications, and management of rare complications in low-resource settings. Little additional research is needed regarding the safety and efficacy of standard sterilization approaches and occlusion methods. There is a need for continued development of nonsurgical methods of sterilization, microlaparoscopic approaches performed in the office setting, and the feasibility and acceptance of service provision by nonspecialist health care providers. The evidence indicates that female sterilization can be performed safely in a variety of resource settings ranging from rural sterilization camps in developing countries to high-tech, resource-rich operating rooms in developed c

Contraceptive status and sexual function of climacteric Chinese women

The objective of the present survey was to assess the contraceptive status and sexual function of climacteric Chinese women. One cross-sectional study randomly recruited 742 premenopausal, perimenopausal, and naturally menopausal women aged 45-55 years from Beijing. Contraceptive methods were used by 75.6% of premenopausal and 54.2% of perimenopausal women. The primary methods were the IUD and barrier method. The women's choices of methods were related to parity and frequency of sexual activities. Sexual activity was related to the satisfaction of contraceptive methods. Perimenopausal and postmenopausal women were about half as likely to enjoy sexual activity and to experience orgasms than premenopausal women. Women of higher socioeconomic status had a lower risk for decreased sexual functioning. The IUD was the most popular and the most appropriate contraceptive method for perimenopausal women. Sexual function was associated with the women's satisfaction with the contraceptive method used, their menopausal status, and their socioeconomic class.

Influence of previous bilateral partial tubal resection on symptoms, hormones, lipids, and bone density in postmenopausal women

The late effect of bilateral partial tubal resection (BPTR) on symptoms, hormone and lipid levels, and bone density in postmenopausal women was analyzed. Thirty-six postmenopausal women in whom BPTR was accomplished were studied; they were matched by age with a group without BPTR. They were subdivided according to time since BPTR into two groups: < or = 15 years > 15 years since the procedure. In both groups, the patients' general data were analyzed as well as the frequency of climacteric symptoms; serum levels of follicule-stimulating hormone (FSH), estradiol, total cholesterol, HDL-C, LDL-C, and triglycerides; and bone density in lumbar spine, femoral neck, Ward's triangle, and trochanter. The statistical analysis was done for the symptoms with chi-squared and for the rest of variables with Student's t-test. When comparing the groups, no differences were found in analyzed parameters; only hot flashes and sweating associated with hot flashes were frequently found in the BPTR group when the analysis was done in the group without any division. With the groups subdivided, hot flashes were found more frequently in the group for whom it had been more than 15 years since the BPTR procedure. The BPTR did not influence hormone and lipid levels or bone density.

Increased uterine and ovarian vascular resistance following Filshie clip sterilization: preliminary findings obtained with color Doppler ultrasonography

The effect of Filshie clip sterilization on uterine and ovarian circulation was studied with color Doppler ultrasonography in 16 women before and twice after the operation. As a whole, the vascular resistance was slightly raised in the largest uterine artery and in the fundal parts of the uterine arteries; likewise in the ovarian arteries 2 days after sterilization. The resistance in the uterine arteries approached the presterilization level at 3 months after the operation, although these changes were not statistically significant. Two women had pelvic pain in the first days after the procedure, and they were compared with the symptom-free patients. Two days after sterilization, the patients with pain had significantly higher vascular resistance in all parts of the uterine arteries as compared to the symptom-free patients. After 3 months the difference had decreased in the largest uterine arteries and in the middle parts of the uterine arteries, but in the fundal parts the resistance was still higher than before sterilization. Vascular resistance in the ovarian arteries was increased in both groups, although the elevation was more pronounced in patients with pain. These preliminary findings imply that sterilization may cause an increase in the local vascular resistance, which is measurable by color Doppler sonography.

Female sterilisation

Adverse effects of female sterilisation are a popular subject for media focus; however, in reality modern techniques mean that the benefits outweigh the risks.
