Laparoscopic management of an ectopic pregnancy in a lower segment cesarean section scar: a review and case report.

Implantation of a pregnancy within the scar of a previous cesarean delivery is the rarest of ectopic pregnancy locations, with only 32 cases reported in the English-language medical literature. A 28-year-old woman was admitted to our institution with a suspected ectopic pregnancy located in the scar from a previous cesarean section. Ultrasound revealed a well-encapsulated, bulging mass with a gestational sac within the anterior uterine isthmus in the site of an old cesarean delivery scar. Laparoscopy was performed to confirm the diagnosis, and the gestational products also were removed laparoscopically. The defect in the uterus was then repaired by suturing. Total operative time was 120 minutes, blood loss was limited, and no transfusion was needed. Laparoscopy may be a reasonable alternative to laparotomy for an unruptured ectopic pregnancy in a cesarean scar.
