Abstract

Objective: To determine the frequency of tubal ectopic pregnancy and to evaluate the epidemiological and common predisposing factors in cases study. To determine the mode of management of tubal ectopic pregnancy.

Study Design: This is a prospective descriptive analytic study carried out from 1 January 2013 until 31 December 2013 at obstetric and gynecological unit at Al-Thawra Hospital in Sana’a, Yemen.

Results: Total number of deliveries from the 1st of January 2013 till the 31st of December 2013, were a total of 9330 deliveries, out of which 103 women had tubal ectopic pregnancy creating an incidence of 1.1% of the total deliveries with a ratio of 11/1000 live births. The mean age of the patients was 27.8 yrs and ranged between 17-40 years of age. It was most common in multipara with a percentage of 78.67 54.4% of women were Qat chewers and smokers. It was more commonly found in women of low economic status with 90.3%. 30.1% of women with it had a history of abortion, 70.9% had a history of pelvic inflammatory disease, 20.8% had a history of an abdominopelvic surgery, 11.7% were using intrauterine device and 5.8% were using progesterone-only pills, 1.9% had a history of tubal sterilization, 88.3% presented with abdominal pain, 72.8% gave a history of amenorrhea, 63.1% presented with vaginal bleeding, 79.6% presented with hemodynamic instability, 86.5% were treated surgically, and 14.5% were treated medically using Methotrexate. The surgical treatment was salpingectomy in 90.4%, and 6.6% was salpingostomy. There were no maternal mortalities.

Conclusion: The most common risk factors found in patients with tubal ectopic pregnancy were previous abortions and PID. The majority of the patients were treated surgically as they were lately presented in a state of hemodynamic instability. 14.5% were treated medically and this proved to be very effective.

Introduction

Tubal ectopic pregnancy is a common life-threatening emergency in pregnancy and the leading cause of death in the first trimester [1,2]. It results in significant morbidity for the mother, and inevitable loss of pregnancy [3]. Tubal ectopic pregnancy is an important cause of maternal morbidity and mortality especially in developing countries where the majority of the patients tend to present lately with rupture ectopic and hemodynamic compromise. The risk of death from extra-uterine pregnancy is 10 times more than that of vaginal delivery, and 50 times greater than induced abortion [4]. Ectopic pregnancy is defined as a pregnancy where the implantation of the blastocyst occurs outside the uterine cavity, most frequently within the fallopian tube (ampullary, ischemic, and interstitial portions of the tube). The incidence of ectopic pregnancy varies from country to country, and within the same geographical regions, depending on the risk factors in the population concerns [5]. The incidence in the western world ranges between 1-3% of all pregnancies [6,7], in Saudi Arabia the prevalence is between 0.58-1.13% [8,9]. Several risk factors for ectopic pregnancy have been identified, including a history of pelvic inflammatory disease, smoking at the time of conception, previous ectopic pregnancy, previous pelvic surgery, induction of ovulation, and intrauterine device usage. An understanding of the risk factors for ectopic pregnancy assists in a more rapid diagnosis, good result in reduction of need of surgery, and suggesting actions to improve prognosis [10]. An early and reliable diagnosis of ectopic pregnancy avoids the high incidence of maternal morbidity and mortality, and preserves future fertility [11]. Nowadays, the use of radio-immune assay for studying serum beta human chorionic gonadotropin (βHCG), the use of pelvic ultrasonography mainly transvaginal sonography, and use of diagnostic laparoscopy enables the gynecologist to diagnose ectopic pregnancy in an early stage before the beginning of any complications [12,13]. In most cases of ectopic pregnancy, surgical intervention is mandatory because of life-threatening intraperitoneal bleeding. Enraptured ectopic pregnancy can be treated by operation, medically, or by careful observation. Ectopic pregnancy is a tragedy of reproduction, and a form of reproductive failure in index pregnancy of effected women. Such women have a 7-15% chance of recurrence, and only 40-60% chance of conceiving after surgery [14]. Ectopic pregnancy presents a major health problem for women of childbearing age, and if not treated vigorously and early enough it may be fatal and is of immerse concern to reproductive health and is associated with significant maternal morbidity and mortality. The aim of this study is to find the magnitude of ectopic pregnancy in our country, and to determine some of the epidemiological and common risk factors in the case study.

Objective

To determine the incidence of tubal ectopic pregnancy in Al- Thawra general modern hospital. To determine epidemiological and common risk factors in the cases studied. To determine the mode of management of tubal ectopic pregnancy.

Methodology

Study design

This is a prospective, descriptive, analytic study done from January 1st December 31st 2013, carried out in the obstetric and gynecological department of Al-Thawra general modern hospital, which is the largest referral hospital in Sana’a, Yemen.

103 women were admitted to Al-Thawra general modern hospital with tubal ectopic pregnancy during the study period. The data was collected by interviewing face-to-face, and a direct questionnaire specially designed for the study which was filled by the author personally and includes the epidemiological and demographic characteristics, clinical presentation on admission, past history of PID, pelvic operation, contraception use, etc., and the type of treatment offered to women of tubal ectopic pregnancy.

All the data collected was coded and statistical analysis was performed using IBMP, and SPPS version 20. All the patients were consulted about their condition and consent was taken from them.

Results

During the study period, from the 1^st of January 2013 till the 31^st of December 2013, there were a total of 9330 deliveries, out of which 103 women had tubal ectopic pregnancy creating an incidence of 1.1% of the total deliveries with a ratio of 11/1000 live births Figure 1.

Discussion

Ectopic pregnancy is a common life-threatening emergency in pregnancy and a leading cause of pregnancy death in the first trimester [15,16]. It results in significant morbidity for the mother and inevitable loss of pregnancy [1,2,3]. Ectopic pregnancy is major cause of maternal morbidity and mortality, especially in developing countries where the majority of patients tend to present late with a ruptured form and hemodynamic compromise. During the study period from Jan. 1st-Dec. 31st 2013, the incidence of tubal ectopic pregnancy was 1.1% with a ratio of 11/1000 live births. The incidence was similar to a study which was performed in Saudi Arabia [17,18] and a study performed by Mehboob U done in Pakistan.

In the USA, the rate is increasing annually and is approaching epidemic proportion. The reported incidence in 1993 ranged from 1/80-1/200 live births [19]. The steady increase of ectopic pregnancy in the USA, as well as in several European countries during the past 25 years, could be attributed to an increased incidence of salpingitis, a major risk, as well as improved diagnostic techniques [20]. In this study, the incidence of ectopic pregnancy is lower than that of developing countries being nearly similar to the incidence of developed countries 20 years back. This could be attributed to the fact that the etiological factors that have increased the incidence of ectopic pregnancy are less common in our society. The incidence of ectopic pregnancy was found most commonly among multiparous women (78.6%) and in the age group of 25-29 years (39.8%), the mean age being 27.8 years. This is similar to the study done by Romero et al [21]. Thus, the reproductive age is the risky period for having ectopic pregnancy and this correlates with the findings of Udigwee and et al [2], and Etuknwa [22]. In the study done by Manjui et al [23], it was found that incidence of ectopic pregnancy is higher among nilipara women, which conflicts with the result of our study [24]. In this study, it was found that ectopic pregnancy was more commonly found among women of low economic status (90%). This may be due to not using contraception, liability to develop infection, or not seeking medical advice, as they are not capable of affording the treatment. In this study, the incidence of ectopic pregnancy was found higher among women who were smoking and chewing Qat (54.4%). There is no study until now showing the association of Qat chewing and ectopic pregnancy. However, Qat chewing may interfere with the motility of the fallopian tube. 69.9% of women had a history of PID, 67% had a previous abortion, and 28.2% had a history of abdominopelvic surgery. These are the most common risk factors which are associated with ectopic pregnancy. These findings were similar to those found in a study done in a maternity hospital in France, which reported that PID, smoking at the time of conception, prior pelvic surgery, induction of ovulation, and maternal age are associated with ectopic pregnancy [25,26]. In a large case controlled study performed in France, it was proven that PID is a major cause of ectopic pregnancy [27]. The majority of women (80.6%) in our study were not using contraception. In a study done by WHO, women who used contraception were less likely to have ectopic pregnancy when compared to non-users [28]. However, in women using progesterone-only pills or IUD the chance of the pregnancy being ectopic was increased. This is because the IUD reduces intra-uterine pregnancy by 99.5% and tubal implantation by 95% [29]. 90% of women in our study presented with abdominal pain, and 72.8% had a history of amenorrhea. This is similar to a study done by Tang BD et al, done in Libya [30,31]. Any woman who comes with pain and amenorrhea should raise the suspicion of ectopic pregnancy. Surgical management was the most common mode of management in our study, as 88 women underwent laparotomy since most of the patients (90%) were presented late with rupture ectopic and internal bleeding. Salpingectomy was performed in 93.3% and salpingostomy in 6.4% to conserve tubal integrity and future fertility. In a study done by Miller & Calendar 1993 [31], it was noted that salpingectomy is a treatment of choice, conservation and repair of tube is unwise even if it appears possible due to the danger of recurrence [28]. Laparoscopy is available in our hospital, but there is an absence of trained physicians to perform this. 14.6% were presented with intact ectopic and were treated with intramuscular methotrexate injections, this proved to be very effective. There were no maternal mortality during the study period.

Conculsion

Early diagnosis of tubal ectopic pregnancy is critically important in order to decrease maternal mortality and morbidity, and to preserve future fertility. Incidence of tubal ectopic pregnancy is 1.1% creating a ratio of 11/1000 live births. Incidence is higher among women of low economic status and those who are smokers, and Qat chewers. PID, previous abortion, previous abdominopelvic surgery, use of intra-uterine device, and history of ectopic pregnancy were the most frequent risk factors associated with ectopic pregnancy. Most of the patients were presented late with ruptured ectopic pregnancy and hemodynamic instability and treated by salpingectomy. Medical treatment of ectopic pregnancy is very effective and can conserve the tube and future fertility.

Due to various presentations of ectopic pregnancy, the physician should always be alert and consider ectopic pregnancy in any woman of reproductive age presented to the emergency room or out patient with history of amenorrhea, and abdominal pain. The first step should be to exclude ectopic Pregnancy. since early diagnosis will preserve fallopian tube and decrease maternal morbidity and mortality. Community based comprehensive health education programs, which focus on contraception, sex education, prevention, treatment of sepsis, and screening program for sexually transmitted diseases should be established.
