Intramesosalpingeal injection of oxytocin in conservative laparoscopic treatment for tubal pregnancy: preliminary results.
The objective of this study was to evaluate the efficacy of the local use of oxytocin as adjuvant treatment in conservative surgery for tubal pregnancy. The patients were 25 women with laparoscopic diagnosis of tubal pregnancy who were candidates for salpingotomy. Before salpingotomy, each patient was randomly allocated to intramesosalpingeal injection of 20 IU oxytocin diluted to 20 ml with saline solution or 20 ml saline solution. The surgeon then proceeded with salpingotomy and removal of the pregnancy according to the usual technique. The main outcome measures were bleeding during salpingotomy, ease of removal of the pregnancy, bleeding at the site of the pregnancy, and need for recourse to salpingectomy. Twelve women were randomized to the oxytocin group and 13 to the control group. Examination of the surgeons' assessments of the difficulties encountered at the different stages of surgery revealed statistically significant differences between the oxytocin group and controls in each variable. In particular, the amount of endosalpingeal bleeding after removal of the pregnancy was less in the oxytocin group. In one control patient, persistent bleeding due to incomplete trophoblast removal forced the surgeon to perform salpingectomy. Our results indicate that intramesosalpingeal injection of oxytocin facilitates the performance of conservative laparoscopic treatment for tubal pregnancy.
