A 26 year old lady presented at 7 weeks of pregnancy with vaginal spotting. She previously had a 10 week miscarriage. A trans-vaginal ultrasound revealed a right sided interstitial pregnancy based on the Timor Tritsch et al criteria. There was a 3.5 x 4.4cm highly vascular cornual mass containing a gestation sac and yolk sac. Herβ-HCG
level was 85,874 IU/L. She was offered emergency laparoscopic surgery. Per rectal Misoprostol 400mcg was administered at induc-tion of anaesthesia to increase myometrial contractility and vasoconstrict the arcuate and spiral arteries. An Endoloop was
placed around the base of the pregnancy to occlude the Sampson artery. A modified Dillon's method where 20IU of Pitressin diluted with 200ml of normal saline was used to minimise cardiovascular compromise. Dillon first described dilution with 100ml of normal
saline in 1958. 60mls was injected beneath the Endoloop with blanching effect. The Harmonic Ace Scalpel was used to perform a cornuostomy and right salpingectomy. Closure was in two contin-uous layers using Stratafix Spiral Poly Dioxanone (PDO) sutures.
PerClot (hydrophilic polysaccharide) was applied for haemostasis and Hyalobarrier gel to reduce adhesion formation. The intra-operative blood loss was 300ml.
