Conservative surgical management of isthmic ectopic pregnancies

During the 12-month study interval ending March 30, 1986, there were 203 ectopic pregnancies at Grady Memorial Hospital, a ratio of one ectopic gestation per 34 deliveries. Twenty patients with isthmic ectopic pregnancies were selected for treatment by one of three operative modalities. Seven patients with ruptured isthmic ectopic pregnancies underwent segmental tubal resection without reanastomosis. All four patients who underwent segmental tuba) resection with primary microsurgical reanastomosis had postoperative hysterosalpingograms demonstrating bilateral tubal patency. One pregnancy has occurred in this group. Nine patients underwent linear salpingostomy. In five of the six patients who had postoperative hysterosalpingography, patency of the involved fallopian tube was demonstrated. Four of these nine patients, including one patient with contralateral tubal occlusion, have conceived. We conclude that linear salpingostomy for isthmic ectopic pregnancies is as effective as segmental tubal resection with primary microsurgical reanastomosis in achieving tubal patency.
