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 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}

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.
