Study Notes
Ectopic Pregnancy
- Defined as pregnancy occurring outside the uterus
- Causes include implantation in the abdomen, fallopian tubes, cervix, ovary, or peritoneal surface.
- Symptoms are variable, commonly including abdominal pain, followed by amenorrhea and vaginal bleeding.
- Women rarely present with dizziness and syncope.
- Clinical signs encompass abdominal and adnexal tenderness, an adnexal mass, and varying uterine size.
- In over 70% of cases, the uterus is of normal size.
- A classic presentation includes abdominal pain, an adnexal mass, peritoneal irritation, and an enlarged uterus.
Differential Diagnosis
- Key differential diagnoses include acute salpingitis, torsion, gastroenteritis, threatened or incomplete abortion, and endometriosis.
- Pelvic inflammatory disease (PID) is a frequent condition confused with ectopic pregnancy.
- Up to 20% of patients with ectopic pregnancy may have temperatures up to 38°C (100.4°F).
- PID is less common in pregnancy (~less than 1% of the time).
Human Chorionic Gonadotropin (hCG)
- In normal intrauterine pregnancies, hCG levels increase by 66% every two days.
- Falling, plateauing, or failure to reach a predicted slope in hCG levels suggests an abnormal pregnancy.
- Serial hCG levels assist in assessing pregnancy viability and identifying the optimal time for ultrasonography.
- Following medical treatment, falling hCG levels help assess treatment effectiveness.
Ultrasound
- Real-time ultrasound examination of the pelvis can help localize a pregnancy.
- Findings depend significantly on gestational age and the type of sonographic approach.
- An interuterine gestational sac is typically visible by the fifth week.
- An embryo or fetal pole may be seen by the sixth week.
- Cardiac motion is often visible by the seventh week.
- Modern transvaginal ultrasound has improved diagnostic accuracy and allows earlier diagnosis of ectopic pregnancies.
Culdocentesis
- Used to determine intraperitoneal hemorrhage if ectopic pregnancy is suspected.
- Positive culdocentesis, indicating intraperitoneal bleeding, suggests a significant risk of ectopic pregnancy rupture.
- Culdocentesis typically involves locating the posterior fornix and inserting a needle to obtain fluid from the cul-de-sac.
Treatment
- Management of unstable patients focuses on hemodynamic support, including oxygen administration.
- Volume resuscitation is started immediately.
- Type-specific blood transfusions are administered as needed.
- Immediate gynecological consultation for surgical management is crucial.
- The risk of repeat ectopic pregnancies is elevated with increasing use of tubal conservation procedures.
- Treatment strategies for stable patients vary depending on the suspicion level and gestational age.
Surgical Treatment
- Laparoscopic surgery progressively replaces laparotomy for initial ectopic pregnancy treatment, offering benefits in terms of reduced morbidity and fertility preservation.
- Tubal conservation procedures, such as linear salpingectomy or segmental resection, can preserve fertility in some cases.
- Persistent ectopic pregnancies or ongoing trophoblast growth after incomplete removal complicate up to 20% of tubal operations.
- Salpingectomy may be required for persistent ectopic pregnancies that lead to hematomas.
- Systemic methotrexate represents a newer approach for treating ectopic pregnancies.
Systemic Methotrexate
- Methotrexate is widely used in treating gestational trophoblastic disease (GTD).
- Its mechanism involves inhibiting purine and pyrimidine synthesis, disrupting DNA synthesis, and thus cell multiplication.
- Stable patients with unruptured ectopic pregnancies less than 4 cm in diameter are eligible for methotrexate therapy.
Ovarian Torsion
- Ovarian torsion is a rare but serious condition involving twisting of the ovarian blood supply.
- The risk of ovarian torsion increases with ovarian enlargement.
- Torsion frequently leads to painful progressive anoxia, followed by eventual ovarian necrosis if not promptly treated
- Ovarian torsion can also accompany masses such as hydrosalpinx, pyosalpinx, and uterine leiomyomas(fibroids) .
Diagnosis of Ovarian Torsion
- Patients typically present with acute, unilateral, lower abdominal and/or pelvic pain.
- Associated symptoms include nausea, vomiting, fever, and abnormal genital bleeding.
- A unilateral adnexal mass is frequently found on examination.
Treatment of Ovarian Torsion
- Laparoscopic treatment, encompassing adnexal conservation or removal, is the preferred treatment approach.
Mittelschmerz
- Mittelschmerz refers to mild to moderate, unilateral lower abdominal pain that occurs around ovulation.
- It is often associated with ovarian follicle rupture.
- Mittelschmerz usually lasts less than a day.
- The pain is typically located midcycle and is characteristically unilateral.
- It may be accompanied by light midcycle endometrial spotting.
Diagnosis and Treatment of Mittelschmerz
- No definitive diagnostic tests are typically employed.
- Treatment usually involves analgesics and/or non-steroidal anti-inflammatory medications.
Abnormal Genital Bleeding
- Pathologic and traumatic causes must be systematically considered for abnormal genital bleeding (nonpregnancy).
- If trauma to the vulva or vagina is suspected, prompt patient stabilization and evaluation of the source of bleeding are crucial.
- Underlying pathologic conditions such as cervical carcinoma require further investigation and potential surgical intervention.
Hemorrhagic Corpus Luteum
- The corpus luteum, a temporary endocrine gland, typically persists up to 8 weeks of gestation.
- Rupture or hemorrhage into the corpus luteum may occur, resembling an ectopic pregnancy clinically.
- Ultrasound is crucial for distinguishing between a hemorrhagic corpus luteum and ectopic pregnancy.
Acute Rupture of Corpus Luteum Cyst
- Surgical intervention, including ovarian cystectomy, is usually necessary for acute rupture, especially in pregnant or nonpregnant cases.
- Outpatient management in presumed instances may be possible under certain circumstances, yet definitive patient observation is recommended.
