Keywords: laparoscopy; methotrexate; tubal pregnancy
Future fertility after ectopic pregnancy is dependent on several factors, including age, history of infertility, history of previous EP, tubal rupture, and contralateral tubal lesion. Thus, it seems reasonable to assess tubal patency following a treatment of an ectopic pregnancy in those women who are willing to have future pregnancy.
Aimed to: Compare between tubal patency after methotrexate & laparoscopic salpingostomy.
The study included 72 patients equally divided in number into 2 main groups.
First group: (36cases) Tubal ectopic pregnancy treated by MXT therapy single or multiple doses. Single dose regimen (MTX 1.0 mg/kg or 50 mg/m2 i.m or multiple dose regimen (MTX 1.0 mg/kg i.m days (0,2,4,6).
Second group: - (36 cases) Tubal ectopic pregnancy treated by laparoscopic salpingostomy.
After 3 months, we used laparoscopy with administration of methylene blue (MB) as a marker to detect the tubal patency.
As regard to tubal patency, of 31 cases (86.1%) from 36 cases that treated by MTX were patent and 5 cases (13.9 %) were blocked. On the other side 21 cases (58.3 %) from 36 cases that treated by laparoscopic salpingostomy were patent and 15 cases (41.7 %) were blocked).
Conclusions:Methotrexate is better than laparoscopic salpingostomy in treating undisturbed tubal pregnancy.
In the western world 4–10 % of pregnancy-related deaths have been observed, from this issue and now it is a growing problem in developing countries also. The annual incidence of ectopic pregnancy has increased over the past 30 years [1].
Although advances in diagnostic methods have allowed for earlier diagnosis, it still remains a life-threatening condition. Approximately, 75 % of deaths in the first trimester and 9 % of all pregnancy-related deaths are due to EP [2].
By the 1920s, laparotomy and ligation of the bleeding vessels with removal of the affected tube had become the standard of care, and it remained so until the late 1970s, when operative laparoscopy and salpingostomy replaced laparotomy and salpingectomy [3]. In the 1980s and 1990s, medical therapy for ectopic pregnancy was implemented; it has now replaced surgical therapy in many cases. Thus, in less than 3 decades, management of ectopic pregnancy has evolved from emergency surgical treatment to conservative medical treatment [4].
Future fertility after ectopic pregnancy is dependent on several factors, including age, history of infertility, history of previous EP, tubal rupture, and contralateral tubal lesion [5]. Thus, it seems reasonable to assess tubal patency following a treatment of an ectopic pregnancy in those women who are willing to have future pregnancy [6].
Study the effect of methotrexate therapy compared with laparoscopic salpingostomy done in the management of EP on subsequent later on tubal patency.
The present study is a prospective study between (2019 -2020). It was conducted at Obstetrics & Gynecology Department Benha University hospital after obtaining informed written consent and ethical committee. The study involved 72 cases, thirty six in each group as average number of patients admitted for tubal pregnancy.
Inclusion criteria:
Exclusion criteria:
The study included 72 patients equally divided in number into 2 main groups:
First group :-( 36cases) Tubal ectopic pregnancy treated by MXT therapy (20 case) by single dose and (16 case) by multiple doses.
Single dose regimen (MTX 1.0 mg/kg i.m), multiple dose regimen (MTX 1.0 mg/kg i.m daily 0,2,4,6).
Second group: - (36 cases) Tubal ectopic pregnancy treated by laparoscopic salpingostomy.
Three months later tubal patency testing for all cases by laparoscopy using methylene blue test.
(Missed period less than or equal to 45 days) at 2-4-day intervals, to examine the rate of increase in HCG values. Measure of serum HCG level at the time of the first transvaginal ultrasound examination, was below the discriminatory zone of 1000 IU/l.
Women who diagnosed as having an ectopic pregnancy. The increase in HCG progressed only slowly, with a doubling time exceeding 2.2 days. The doubling time of HCG is a useful diagnostic aid in cases where transvaginal ultrasound has not (yet) given a definite answer regarding the presence of an intra-uterine pregnancy [7].
A tubal pregnancy should be suspected if ultrasonography reveals gestational tissue in the adnexal area without any evidence of an intrauterine pregnancy. If a yolk sac or embryo is seen in the ectopic gestational tissue, the diagnosis of ectopic pregnancy is definitively confirmed [8].
Laparoscopic procedure:
1-Under general anesthesia was used in all patients. 2-The patient is placed in a dorso-lithotomy position with the buttocks extended over the end of the table. 3-The thighs should be flexed (120°) to allow good instrument manipulation. Sterilization, foley catheter is placed in the bladder. 5-After placement of a cervical tenaculum, a Robins cannula is inserted into the cervix. Laparoscopic salpingostomy. Tubal ectopic pregnancy once diagnosed, first we check the healthy tube then treat the diseased one if the pregnancy is in the mid-ampullary segment as in solution of vasopressin (20 U/100mL the majority of cases, a 5-7 mL dilute of NS) is used. This is injected with a laparoscopic needle into the mesosalpinx just below the pregnancy and over the anti-mesenteric surface of the segment containing the gestation. Using a laser, microelectrode, scissors, or harmonic scalpel a linear incision is made over the pregnancy approximately 1-2 cm in length. As one makes this incision the contents of the pregnancy usually begin to extrude. This can be completed by hydro dissection or using gentle traction with laparoscopic forceps. In some cases, more forceful irrigation in the salpingostomy incision may be required to dislodge the pregnancy from its implantation site. Occasionally, coagulation is used to secure hemostasis and is best accomplished with bipolar micro-forceps. Copious irrigation is used to dislodge trophoblastic tissue and remove blood from the peritoneal cavity. The tubal opening is left to heal by secondary intention, unless the defect is wide, and the edges do not come together spontaneously. For such cases, the edges may be approximated with a single 4-0 absorbable suture [10]
Outcome:
3 to 6 months tubal patency for all cases was evaluated by laparoscopy using methylene blue (MB) test at the time of surgery.
The collected data were computerized and statistically analyzed using SPSS program (Statistical Package for Social Science) version 18.0.
This study included 72 women with ectopic pregnancy, who was treated in Obstetrics and Gynecology Department in Benha University Hospital, by using methotrexate therapy (single or multiple) or laparoscopic salpingostomy. After that, we used laparoscopy with administration of methylene blue (MB) as a marker to detect the tubal patency.

The annual incidence of EP has increased over the past 30 years. Four–10 % of pregnancy-related deaths have been observed due to ectopic pregnancy [10].
Future fertility after ectopic pregnancy is dependent on several factors, including age, history of infertility, history of previous EP, tubal rupture, and contralateral tubal lesion [11]. Thus, it seems reasonable to assess tubal patency following a treatment of an EP in those women who are willing to have future pregnancy.
In present study we detect tubal patency using laparoscopy guided by methylene blue after treatment of tubal pregnancy by methotrexate or laparoscopic salpingostomy.
This study was in Obstetrics & Gynecology Department Benha University hospital. Thirty-six cases treated by administration of MTX & thirty-six cases treated by laparoscopic salpingostomy.
As regard to tubal patency of 31 cases (86.1%) from 36 cases that treated by MTX were patent and 5 cases (13.9 %) were blocked. On the other side 21 cases (58.3 %) from 36 cases that treated by laparoscopic salpingostomy were patent and 15 cases (41.7 %) were blocked.
Comparing Laparoscopic salpingostomy alone versus laparoscopic salpingostomy with single-dose systemic MTX. They reported that salpingostomy alone was significantly less successful than when combined with a prophylactic single dose of systemic 1 mg/kg i.m. MTX (RR 0.89, 95% CI 0.82–0.98), given within 24 h post-operatively to prevent persistent trophoblast [12]. This agrees with our study.
Comparing Systemic MTX in a fixed multiple dose regimen with laparoscopic salpingostomy. They reported that no significant differences were found in tubal patency between the two groups [13].This disagrees with our study due to the difference of gravidity and parity.
Comparing systemic MTX in a single-dose regimen with laparoscopic salpingostomy. They reported that no significant differences were found in tubal patency between the two groups [14].
This disagrees with our study because they used only single dose MTX regimen, but we used single or multiple doses.
Comparing systemic MTX in a single-dose regimen with laparoscopic salpingostomy. They reported that tubal patency in patients treated with methotrexate was 84% and in salpingostomy patients it was 83%. The success rate for tubal patency with methotrexate was the same as that for surgery [15].
This disagrees with our study due to their higher levels of hCG-β that reduce the chance of tube patency.
Comparing medical versus surgical treatment. They reported that systemic treatment with variable dose methotrexate regimen is as effective as laparoscopic salpingostomy (82 – 95% MTX Vs 80-92% Salpingostomy) [16]. This agrees with our study.
Methotrexate is better than laparoscopic salpingostomy in treating undisturbed tubal pregnancy.
