Objective:
To evaluate endometrial stripe thickness (EST) among patients with tubal pregnancy (TP) and intrauterine pregnancy (IUP).
Design:
Historical cohort.
Setting:
City hospital.
Patient(S):
Ninety-four women suspected to have TP.
Intervention(S):
Serum betaHCG and sonographic EST measurements.
Main Outcome Measure(S):
Comparison of age, gestational age (GA), EST, and log beta HCG.
Result(S):
The two groups of women, 65 with TP and 29 with IUP, had similar mean ages (+/-SD) of 28.6 +/- 5.7 and 28.6 +/- 6.1, respectively. The median values of GA in the 2 groups were similar, 46.6 and 44.6 d, respectively. The mean values for EST (+/-SD), adjusted for GA, were significantly different: 9.9 +/- 5.9 mm in the TP group and 12.6 +/- 5.3 mm in the IUP group. The mean values (+/-SD) of log beta HCG in the 2 groups also differed significantly: 6.90 +/- 1.29 and 7.52 +/- 0.97, respectively. No correlation was found between EST and GA or log beta HCG within either group.
Conclusion(S):
The mean EST in women with TP was significantly smaller than in women with IUP. The wide range of EST values and their overlap precludes the utilization of EST as a single feature in the diagnosis of a tubal pregnancy.
