A young lady with 6 weeks amenorrhea had nausea and vomiting with severe abdominal pain. Her BP was 100/80 mm Hg. Examination revealed a 5 x 5 cm adnexal mass. Is What the plan of management?
High-Yield Explanation
Ans-A Plan for immediate laparoscopic surgery (Ref: Dutta 7/e p180-182; Williams Obstetrics 24/e p385)In this patient, the size of an adnexal mass is 5 x 5 cm so expectant management cannot be done. But since the patient is hemodynamically stable, laparoscopic surgery will be the management of choice."Ectopic Pregnancy: Laparoscopy is the preferred surgical treatment for ectopic pregnancy unless a woman is hemodynamically unstable. "--Williams Obstetrics 24/e p385Ectopic PregnancyDefinition: Fertilized ovum implanted and developed outside the normal uterine cavity.
