title: Persistent tubal ectopic gestation: patterns of circulating beta-human chorionic gonadotropin and progesterone, and management options.
abstract: To aid in the clinical decision making involved with persistent ectopic gestation, a total of 329 operative procedures for tubal gestation were reviewed. Six of 114 (5.3%) cases treated conservatively had persistent trophoblastic activity. The decline in serum beta-human chorionic gonadotropin (hCG) and progesterone (P) at 3 and 6 days postoperatively was similar in the "persistent ectopic" and the "resolved ectopic" groups. However, beyond day 6 both beta-hCG percentage of baseline and P level were significantly higher in the "persistent ectopic" (greater than 22.6 +/- 6.6%, greater than 3.4 +/- 0.7 ng/ml, respectively) than the "resolved ectopic" group (less than 2.7 +/- 0.8%, less than 0.2 +/- 0.05 ng/ml, respectively). Four patients underwent a second operation, whereas two were managed expectantly. These data suggest that the diagnosis of persistent ectopic gestation is best made by an initial measurement of serum beta-hCG or P at 6 days postoperatively, and at 3 day intervals thereafter. The choice of management may be determined by various factors including serum beta-hCG and patient's symptoms.
