Acute abdomen in ruptured interstitial pregnancy following unilateral salpingectomy.

Interstitial pregnancy is an infrequent type of ectopic pregnancy. Two cases of acute abdomen due to ruptured interstitial pregnancy following salpingectomy, a rare event, are presented. Both patients were young women who had had a previous salpingo-oophorectomy due to ovarian cyst. The presenting symptoms were in the first case abdominal pain followed by hemorrhagic shock, and in the second a right iliac fossa syndrome simulating acute appendicitis. Surgical intervention consisted of wedge resection of the uterine segment involved. A review of the literature and practical considerations are presented.
