ABSTRACT

Background: Ectopic pregnancy is still a global problem for women of reproductive age with increasing burden of the disease and increasing mortality especially for women living developing world like Africa. In Ghana studies evaluating the burden of ectopic pregnancy have been conducted in major centres like Korle-Bu and KATH but few in other centres. This study tends to evaluate the prevalence, clinical presentation and finding of ectopic pregnancy in a referral hospital in the Volta region of Ghana. Methodology: This was a 3 years (2013-2016) retrospective review of all gynaecological admission in the Volta regional hospital. All ectopic pregnancy cases/ record were identified, retrieved and information on the socio-demographics, clinical presentations, intraoperative findings and outcome of surgery were all extracted for analysis. Result: A prevalence of 2.05% (53/2582) was recorded over the study period. 58.5% (31/53) of the women were married and between the age group of 21 - 30. 47.2% (25/53) had primary school education. Lower abdominal pain was common in 98.1% (52//53), 69.2% (37/53) had vaginal bleeding while 96.4% (51/53). Fallopian tube pregnancy was seen in 96.2% (51/53) while 3.8% (2/53) were abdominal pregnancy. Tubal rupture and heamoperitoneum were seen in 73.6% (39/53) of the women. 78.4% (40/51) of the fallopian tube pregnancy occurred at the ampulla. All the women in this study were successfully managed with radical surgery. Conclusion: There is still the need to evaluate the prevalence of ectopic pregnancy in the region. Proper education of women of reproductive age and provision of equipment and skills to enable early diagnosis of ectopic pregnancy is very necessary in ensuring less radical and traumatic management with less implication on fertility of women post-surgery.

1. Introduction

Ectopic pregnancy is serious life threatening gynaecological emergency. It can be defined as the abnormal implantation of fertilized ovum or blastocyst at sites other than the endometrial cavity of the uterus and very commonly the distal portion of the fallopian tube [1] . It has an estimated global prevalence of 1% - 2% with the United Kingdom recording 12,000 yearly translating to about 1.1% [2] . Centre for disease control in the United States of America showed an increase incidence ectopic pregnancy from 1.9% to 2.2% of live births between 1981 to 1991 [3] . In a similar study conducted in Norway between 1976 and 1993, the incidence of ectopic pregnancy increased from 1.4% to 2.2% of live births. [4] .Though ectopic pregnancy is the leading cause of pregnancy-related death in early pregnancy [5] , in developed countries like USA, the UK and most countries in Europe there is a steady decline of ectopic pregnancy case fatality rates despite the documented increase in prevalence [6] [7] . Unfortunately the same cannot be said with developing countries as many hospital based studies from the region reported a 10 times higher case-fatality rate compared to develop countries [8] . One of the reasons for this worrying discrepancy between developed and developing countries is late diagnosis, as these women explore other precarious unorthodox means for treatment of their problem leading to late arrival in hospital [8] . Another reason is the lack diagnostic equipment for early diagnosis like transvaginal ultrasound and β-HCG test [5] [9] .

Ectopic pregnancy can present with abdominal pain, amenorrhea or vaginal bleeding. These three symptoms occurring simultaneously in a patient is known as a clinical triad and although regarded as very specific for ectopic pregnancy [10] , it is absent in close to 45% of cases [11] . Lower abdominal pain is fairly constant, present in 80% - 100% of cases with varied severity [2] [12] . Amenorrhea, on the other hand, is reported by 75% - 90% [12] . Vaginal bleeding is another common symptom but 10% - 20% of women do not present with it [13] .

In Ghana, like most African countries diagnosis, treatment and management of ectopic pregnancy is still a big issue making ectopic pregnancy a threat to the health of women of reproductive age [14] . Studies done showed 10.6% burden of ectopic pregnancy in all gynecological admission in Komfo Anokye Teaching Hospital Kumasi [15] and 32.90 per 1000 deliveries in Korle-bu Teaching Hospital in Accra [14] . There is however little or no data on the prevalence or incidence of ectopic pregnancy in other parts of the country especially the Volta region of Ghana. This study looked at the prevalence of ectopic pregnancy and clinical presentation and findings in the Volta Regional hospital of Ghana

2. Methodology

2.1. Study Area

The study was conducted at the Volta regional Hospital located in Ho. Ho is the regional capital of Volta region of Ghana and it has a population of approximately 177,281 representing 8.4 percent of the region’s total population according to the 2010 Population and Housing Census. This makes it the most populous district in the Volta Region. The hospital is a referral center which serves people from all the districts in the region and even beyond.

2.2. Study Design

This was a retrospective, descriptive study of ectopic pregnancies managed in Volta regional hospital during the study period (July 1st, 2013 to March 31st, 2016). The hospital has a yearly admission of almost 16,000. All gynecological admissions during the study period was reviewed, and the medical records of those diagnosed and confirmed as ectopic pregnancy was retrieved and information on the age, education, marital status, occupation, parity, clinical presentation and surgical findings were collected with the aid of data-entry forms designed for this purpose. Only patient with a confirmed diagnosis of ectopic pregnancy were included in this study.

2.3. Data Entry, Management and Analysis

The data collected was organized with Microsoft excel 2010 and analyzed using SPSS (Statistical Package for the Social Sciences, SPSS Inc., Chicago), version 20.0 for Windows. Data was analyzed using descriptive and multiple response statistic methods. Categorical variables were presented as tables and graphs with absolute frequencies.

2.4. Ethical Clearance

Ethical clearance was obtained from the Ghana health service Ethics Review Committee (ERC). GHS-ERC 57/02/16.

3. Result

A total of 2582 cases were admitted in the gynecology ward of the hospital during the period under study. Fifty-three (2.05%) of these cases were diagnosed as Ectopic pregnancy.

Table 1 shows the general characteristics of the women with ectopic pregnancy. Majority of the women diagnosed with ectopic pregnancy were between the ages of 21 - 30 (58.5%), and the least diagnosed are women between the ages of 10 - 20 (7.5%) and 41 - 50 (3.8%). The mean age of the women in this study was 28.8 yrs (not shown). Married women were most diagnosed (31, 58.5%) compared with single women (16, 30.2%) and

women who were cohabiting (6, 11.3%). Women who had secondary or higher education had the least diagnosis (12, 22.6%), while women with primary education were most diagnosed (25, 47.2%). Sixteen (30.2%) of the women diagnosed had no education at all. Women employed in the informal sector had the highest diagnosis (21, 39.6%) while unemployed students had the lowest diagnosis (7.5%). Majority of the women with ectopic pregnancy in this study were multiparous (29, 54.7%) and the least were primiparous women (5, 9.4%). Nearly 53% (28) of the women were referrals and 47.2% (25) were not.

Table 2 showed the clinical presentation of the women with ectopic pregnancy. Majority of the women presented with lower abdominal pain (52, 98.1%), abdominal pain (50, 94.4%) and amenorrhea (51, 96.2%), while some women presented with vaginal bleeding (37, 69.8%) and the clinical triad (60.4%). Urine pregnancy test was done for all the women and majority of them tested positive (50, 94.3%). 86.8% (46) of the women had ultrasound done. Most of the women in this study were anaemic with 26.4% (14) severely anemic (<7 g/dl), 47.2% (25) moderately anemic (7 - 9.9 g/dl), and 15.1% (8) mildly anemic (10% - 10.9%) [16] .

Intraoperative findings showed that the fallopian tube was the more frequent site of the ectopic pregnancy (51, 96.2%), compared to abdominal pregnancy (2, 3.8%) (Table 3). Of the findings in the fallopian tube, the ampulla was the most common followed by the cornu and ovary corresponding to 78% (40) and 8% (4) respectively. There was no case of broad ligament pregnancy (Figure 1). Table 3 also shows that the left fallopian tube was more frequently involved (32, 60.4%) than the right (19, 35.8%). Thirty-nine of these women had tubal rupture and hemoperitonuem, 46 had salpingectomy performed, 5 had Salpingoophorectomy and 2 had abdominal excision of the ectopic pregnancy done on them. There was 100% success in this study as no casualty was recorded all the women in this study successfully had surgery and satisfactorily discharged home.

4. Discussion

This study recorded a 2.05% prevalence of ectopic pregnancy in the VRH. This rate is low relative to prevalence of 10.6% reported in a study done in Komfo Anokye Teaching Hospital Kumasi Ghana [15] , 6.5% in Nnamdi Azikiwe University teaching hospital

Nnewi, Nigeria [17] and 6.9% in Bugando Medical Centre, Mwanza, Tanzania [18] . All these studies used gynaecological admission as their baseline. The difference between the prevalence of our study and that of others might be attributed 1) to duration of study, 2) patient-hospital dynamics, 3) health seeking behavior of the population and accessibility of health care facilities. Majority of the women in this study are married and between the ages of 21 - 30 with a mean age of 28.8. This is similar to the work done in Nigeria and Tanzania [17] [18] . The age range of 21 - 30 and marital status are very likely related to increase sexual activity which might increase the chances of pregnancy. Poor educational background (no formal and primary school education) was predominantly seen in women with ectopic pregnancy in this study, similar to findings in Tanzania study [18] . This finding is corroborated by previous work which suggested that illiteracy negatively impacts on the sexual and general health of women [19] [20] .

The clinical presentation of the classical symptoms of lower abdominal pain, vaginal bleeding, amenorrhea and the classical triad in this study were consistent with the findings of other studies done in Africa and Asia [11] [17] [18] [21] .

Findings from this study further support the fact that fallopian tube is the commonest site for ectopic pregnancy [1] . Tubal rupture was seen in 73.5% of the women in this study, probably suggesting late diagnosis of ectopic pregnancy which is common feature in most African settings [8] [14] [17] [18] [21] [22] . The left fallopian tube was more involved with ectopic pregnancy in this study. This is in contrast with studies done in Nigeria and Tanzania [17] [18] [23] . The ampulla was the common site of the fallopian tube that was involve and this is consistent with other studies [18] [24] . Broad ligament ectopic pregnancy was not seen in this study. This is in support of work by others suggesting it is a rare form of ectopic pregnancy, and reported with less frequency [18] [25] [26] . There was no room for tubal conservative management for the women in this study as all the women either had salpingectomy or Salpingoophorectomy. Late diagnosis of the ectopic pregnancy could probably be due to patient time of arrival to hospital or lack of transvaginal ultrasound. These might be responsible for the use of surgery in this study [8] [14] [17] . Though all the women survived the surgery in this study, early diagnosis and nonsurgical conservative management should be the ultimate goal; as radical salpingectomy and salpingoophorectomy aside the physical and psychological trauma on the women, have been implicated in reduced fertility and reoccurrence of ectopic pregnancy [27] [28] .

5. Conclusion

The 2.05% prevalence of ectopic pregnancy in no way suggests a regional prevalence. Though the center, where this study, was conducted is the referral hospital for the region, other hospitals clinics in the region might have received and managed cases of ectopic pregnancy. Also some women might not have made it to the hospital. It is very important that a more regional study is conducted to evaluate the burden of this problem. It is also important to educate women on the signs and symptoms of ectopic pregnancy and to equip hospitals and clinics with equipment and skills to make early diagnoses of ectopic pregnancy. A regular scheduled after care should be recommended to conserve the remaining tube.
