Cornual ectopic pregnancy: laparoscopic management step by step

Abstract

Cornual (interstitial) ectopic pregnancy is an uncommon type of ectopic pregnancy which is located in the interstitial part of the fallopian tube. It accounts for 2%-4% of all ectopic pregnancies. Cornual pregnancies often pose a diagnostic and therapeutic challenge with a significant high morbidity and mortality as a result of massive intraperitoneal bleeding. A case of unruptured cornual ectopic pregnancy in a patient with abnormal uterine bleeding is reported which was successfully managed laparoscopically.

Methotrexate for Cornual Ectopic Pregnancy

“…Cornual ectopic pregnancy (interstitial pregnancy) is a rare type of ectopic pregnancy that occurs in roughly 2%-4% of ectopic pregnancies and 1/2,500-1/5,000 of all pregnancies [1][2][3][4][5][6]. The embryo embeds itself into the funnel-shaped area where the uterus connects to the fallopian tubes [1].…”

“…The embryo embeds itself into the funnel-shaped area where the uterus connects to the fallopian tubes [1]. Cornual pregnancies pose a diagnostic and therapeutic challenge with significant high morbidity and mortality (2.2%-2.5%) and are associated with massive intraperitoneal bleeding during the first trimester [2,3,5,13]. Without early and rapid diagnosis and treatment, the gestational sac grows to cause uterine rupture and bleeding [2,14].…”

“…Cornual pregnancies pose a diagnostic and therapeutic challenge with significant high morbidity and mortality (2.2%-2.5%) and are associated with massive intraperitoneal bleeding during the first trimester [2,3,5,13]. Without early and rapid diagnosis and treatment, the gestational sac grows to cause uterine rupture and bleeding [2,14]. Cornual ectopic pregnancies, like other ectopic pregnancies, include a high level of serum beta-hCG, persistent light vaginal bleeding despite amenorrhea, and sometimes early pelvic pain [2].…”

“…Without early and rapid diagnosis and treatment, the gestational sac grows to cause uterine rupture and bleeding [2,14]. Cornual ectopic pregnancies, like other ectopic pregnancies, include a high level of serum beta-hCG, persistent light vaginal bleeding despite amenorrhea, and sometimes early pelvic pain [2]. Increased incidence of cornual ectopic pregnancy is associated with assisted reproductive technologies, previous salpingectomy or other tubal surgery, rudimentary horn, history of infections of the reproductive tract, or previous tubal pregnancy and proximal intratubal adhesions.…”

“…Ectopic pregnancy is a pregnancy outside of the uterine cavity. In about 4% of ectopic pregnancy, it can involve the cornua [1][2][3][4][5][6]. Cornual pregnancy is a rare type of ectopic pregnancy in which the embryo implants in the junction between the fallopian tube and the uterus [4,7].…”
