PathogenesisPathogenesis
• Ability tube transport gametes embryos
• Clinical picture site E.P
• Most common site Tub 98-3%
• Ampoule – isthmus – fimbrial cornual.
• Rarely abdominal – ovarian – cervical.
![Page 5: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/5.jpg)
• Proliferating trophoblast
• Tubale wall
• Growth may extend luminal mucosa.
• Muscularis- serosa full thickness blood vessels
• Distorts tube stretches serosa → pain bleeding
takes phase.
• 80% embryo degenerates.
• 50% often clinically silent.
• Tubal abortion self limited.

Risk factors Needs aggressive monitoring pregnancy
immediately after first missed menses High risk
• Tubal surgery (21) • Risk factors• Tubal ligation • Tubal Epithelial damage.• Previous E.P (6-8)• I U D , Morning after pill • A R T

• Moderate risk
• Infertility
• P I D
• Multiple sexual partners
• Salpingitis
Low risk
• Cigarette
• Vaginal douching first intercourse <18

• Signs and symptoms
• Many E.P never produce symptoms rather
• Timely diagnosed and treated (H.R)
• If diagnosis → delayed → classic triad.
• Amenorrhea , irregular V.B , lower ab- pain.
• Sudden sever ab pain 90-100% symptomatic patient.
• Pain radiating shoulder.
• Syncope shock → hemoperitaneum.( up to 20%)

• Most common signs ab EX
• 90% tenderness ,rebound tenderness in 70%.
• P.EX nonspecific.
• 2⁄3 C-motion tenderness .
• Adnexal mass 50%.

• Diagnosis
• Diag as early as 4.5 WK.
• Visualization is frequently not possible.
• Traditional laparoscopic visualization rarely necessary.
• Routine diagnostic Tests.
• Serial 3HCG.
• U.S
• Progesterone levels.
• U - curettage.

Treatment for E.PTreatment for E.P• Medical management .• Methotrexate therapy. • Folic acid antagonist • DNA synthesis and cell multiplication.• Single dose 50 mg/m2
• Blunts HCG increment (7)• Drop progesterone, 17 × hydroxy progesterone prior to
abortion• Hemodiamically stable. • E.P unruptured less 4cm• Eligible for methatrexate therapy.
![Page 13: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/13.jpg)
Multiple-dose: tailored weight-E.P responsiveness.
• Comparing multiple-dose-laparoscopic salpingostomy.
• Patent fallopian tubes.
• Subsequent IU pregnancy.
• Repeat E.P comparable .
Single dose:
• Resent metaanalysis 26 studies.
• Based on clinical evidence presently available.
• Routine use methotrexate single dose IM not as
• Effective as multiple dose (tubal rupture↑)
![Page 14: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/14.jpg)
• Indication for systemic M-dose methotrexate
• No rupture
• Tubal size ≤4cm
• HCG ≤ 10,000
• Positive F.H heartbeat proceed with caution.

Methotrexate by direct injection Methotrexate by direct injection
• Methotrexate E. gestational sac TVS.• Resolution within 2 weeks• Higher concentrations site of implantation.• Less systemic distribution drug• 75.1% successfully treated • Subsequent p–tubal patency (laparoscopic-
systemic Mehta)• Subsequent – P, recurrent E.P

Methotrexate failureMethotrexate failure
Pain is sever and persistent (>12h 4-12
3-7 after start therapy)
Falling HCT
Orthostatic hypotension.

Surgical TreatmentSurgical Treatment
• 1884 E.P laparotomy salpingectom.
• 1953 salpingostomy
• Manual fimbrial expression
• Segmental resection.
![Page 19: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/19.jpg)
• Ruptured E.P
• Laparoscopy – laparotomy – salpingectomy.
• Inpatients hypovolemic shock.
• Surgery is choice.
![Page 20: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/20.jpg)
Stable E.P
• If methotrexate contraindicated.
• Laparoscopic salpigostomy first surgical choice.
• Salpingectomy
Laparoscopy
Laparotomy

Expectant managementExpectant management
• E.P may resolve spontaneously
• 67.2% E.P resolved without surgery (over treats)
• Falling 3HCC under 1000 fallowed with
conservative expectant management
• With low initial and falling HCG
![Page 22: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/22.jpg)
Rare types of E.P
• Abdominal pregnancy
• 1⁄8000 birth prognosis poor
• M.M 5.1⁄1000 7.7 higher than other E.P
• (Higher due to delay in diagnosis)
![Page 23: Ectopic pregnancy](https://reader030.vdocuments.us/reader030/viewer/2022033106/5681548f550346895dc29f6a/html5/thumbnails/23.jpg)
Primary - SecondaryPrimary - Secondary• Symptoms → normal for pregnancy to sever if time
permits• Abdominal pain intra abdominal hemorrhage shock• Primary rare usually abort• Secondary (reimplantation → abortion ,rupture)• U.S choice empty uterus • If fetus near viability → hospitalization• Adequate blood, bowel preparation• Placenta removed unless major vessels, vital organ
methotrexate

Ovarian pregnancyOvarian pregnancy• Most common form abdominal pregnancy • less than 3% of E.P• Clinical finding similar tubal E.P• ab-pain ,V.B Amenorrhea• 30% hemodynamic instability → rupture• Usually young multiparous cause • Treatment → systectomy, wedge resection
or oophorectomy

Cornual pregnancy
or interstitial pregnancy
• 4.7% E.P 2.2% M. mortality
• Most frequent symptom menstrual aberration
• Abdominal pain V.B, shock → rapture uterine(9-12nk)
• Risk factor previous salpingectomy
• Repeat U.S with Doppler flow studies → early diagnosis
• Cornual resection lapa - resection systemic methatraxate
local
