The patient has had more pain than is usual in normal pregnancy. The sound may be passed into the uterus to determine that it is empty. At full term, the diagnosis is made by a history of false labor followed by a gradual decrease in the size of the abdomen. The uterus is nearly normal in size and displaced by a large tumor either forward or backward. The child can be palpated and, if alive, the fetal heart sounds can be heard. The diagnosis at full term is easy to make, whereas previous to this time it is difficult. The diagnosis of combined intra- and extra-uterine pregnancy is seldom made previous to labor or operation. Sometimes in the case of twins when a child has been born from the uterus and there is delayed birth of a second child, examination leads to the diagnosis of extra-uterine fetation. Also, operation for ruptured extra- uterine pregnancy with abdominal hemorrhage may show the co-existence of uterine pregnancy.

The differential diagnosis of extra-uterine pregnancy includes conditions such as ruptured ovarian cysts or pyosalpinx. The treatment is immediate opening of the abdomen in cases of rupture.
<Callout type="risk" title="Risk of Misdiagnosis">Fibroids, retroverted uterus, and other pelvic tumors can be mistaken for extra-uterine pregnancy.</Callout>
Late extra-uterine pregnancy with an excess of hydramnios may simulate ovarian cyst. If the fetus can be outlined by palpation or the fetal heart heard, the diagnosis is easy.
Key Takeaways
- Extra-uterine pregnancy presents with more pain than normal pregnancy and can be diagnosed by physical examination.
- Immediate surgery is required for ruptured extra-uterine pregnancies to prevent hemorrhage.
- Differential diagnosis includes conditions such as ovarian cysts, pyosalpinx, fibroids, and retroverted uterus.
Practical Tips
- Use a sound to determine if the uterus is empty in suspected cases of extra-uterine pregnancy.
- Listen for fetal heart sounds at full term to confirm uterine location of the fetus.
- Be cautious about misdiagnosing fibroids or retroverted uterus as extra-uterine pregnancy.
Warnings & Risks
- Severe abdominal pain, collapse, and thready pulse indicate a ruptured ectopic pregnancy requiring immediate medical intervention.
- Misdiagnosis can lead to delayed treatment and severe complications such as hemorrhage.
Modern Application
While the diagnostic methods described here are outdated, understanding the symptoms of extra-uterine pregnancy remains crucial for survival medicine. Modern ultrasound technology has greatly improved diagnosis accuracy, but recognizing early signs is still vital in remote or resource-limited settings.
Frequently Asked Questions
Q: What are the key symptoms to look out for in diagnosing an ectopic pregnancy?
Key symptoms include severe abdominal pain, collapse, distention and rigidity of the abdomen, thready pulse, and subnormal temperature.
Q: How can one differentiate between a ruptured extra-uterine pregnancy and other conditions like pyosalpinx or ovarian cyst?
Differentiating involves considering the history of the case, such as previous infections for pyosalpinx, and noting that symptoms of hemorrhage are absent in ectopic pregnancies.
Q: What is the importance of immediate surgery in cases of ruptured extra-uterine pregnancy?
Immediate surgery is crucial to prevent severe complications like abdominal hemorrhage which can be fatal if not treated promptly.
