A 30-year-old woman, gravida 4, para 1, visited the outpatient department with prolonged vaginal bleeding and mild right lower abdomen pain at 9 weeks of gestation. Human chorionic gonadotropin level was 15,037 mIU/mL, and transvaginal ultrasonography showed an eccentrically located gestational sac with abundant blood supply [Figure 1]a. Laparoscopy revealed a bulging mass measuring 4 cm × 3 cm with a thin surrounding wall at the root of tubal insertion into the uterus [Figure 1]b. Right cornuotomy was performed to remove the embedded gestational tissues [Figure 1]c. The  Fallopian tube More Details was preserved by repairing with 1-0 monocryl [Figure 1]d. The patient recovered and conceived uneventfully 5 months later with healthy intrauterine pregnancy.
Figure 1: (a) Transvaginal ultrasonography revealed a gestation sac located outside the cavity with abundant blood supply, (b) laparoscopy found the ectopic site as a bulge at the uterotubal junction; the surrounding wall was thin with dilated vessels, (c) after cornuotomy, the gestational sac was removed with an endo-bag, (d) the tube was successfully preserved after suture repair

Interstitial pregnancy is an ectopic pregnancy implanted in the tubal interstitial portion where it traverses through the uterine muscular wall for approximately 1–2 cm to enter the cavity.[1],[2],[3] Surgical management could be carried out with either cornual resection or cornuotomy.[4] Our case demonstrated typical pictures and a conservative process of the laparoscopic surgical treatment.
