Current treatment of ectopic pregnancy

Diagnostic value of detection of serum β-HCG and CT-IgG combined with transvaginal ultrasonography in early tubal pregnancy

The diagnostic value of detection of serum β-human chorionic gonadotropin (β-HCG) and Chlamydia trachomatis immunoglobulin G (CT-IgG) combined with transvaginal ultrasonography in early tubal pregnancy was investigated. A total of 55 patients with early tubal pregnancy were selected as the tubal pregnancy group, while 55 subjects of normal intrauterine pregnancy were enrolled as the intrauterine pregnancy group. Transvaginal ultrasonography and quantitative detection of serum β-HCG and CT-IgG were performed for all patients, and the clinical examination results were analyzed and compared. The endometrial thickness and serum β-HCG level of patients with early tubal pregnancy were significantly lower than those of women with intrauterine pregnancy (6.7±1.5 vs. 11.6±1.2 mm; 776±109 vs. 5,598±187 U/l), and the differences were statistically significant (p<0.01); the serum CT-IgG antibody positive rate of patients in tubal pregnancy group (49.1%) was significantly higher than that in intrauterine pregnancy group (12.7%) (p<0.01); the serum CT-IgG antibody positive rates of patients with degree I, II and III of pelvic adhesion intubal pregnancy group were 28.6, 75.0 and 81.8%, respectively; the more severe the pelvic adhesion was, the higher the CT-IgG positive rate would be. The diagnostic coincidence rate of combined detection was significantly higher than that of single detection of serum β-HCG, progesterone and endometrial thickness. The detection of serum β-HCG and CT-IgG combined with transvaginal ultrasonography can diagnose the early tubal pregnancy soonest possible, and help choose the appropriate therapeutic methods depending on the situation to reduce the tubal damage of patients, so as to provide a reliable basis for the diagnosis, treatment and prognosis, and it has important clinical application value.

Primary twin omental pregnancy: report of a rare case and literature review

OBJECTIVE

To report a very rare case of a primary twin omental pregnancy.

DESIGN

Case report.

SETTING

The emergency department of a university teaching hospital.

PATIENT(S)

A 36-year-old woman.

INTERVENTION(S)

Partial omentectomy by laparotomy.

MAIN OUTCOME MEASURE(S)

Laparotomy successfully performed in the case of a twin omental pregnancy.

RESULT(S)

A 36-year-old woman presented with intense abdominal pain of 3 days' duration, hypotensive, with distended abdomen and signs of peritoneal irritation, and no transvaginal bleeding or evidence of topic pregnancy. Laparotomy showed normal internal genital organs and the presence of a large hemoperitoneum with a twin omental pregnancy. Partial omentectomy was performed. The patient progressed well postoperatively, and subsequent beta-hCG titer was negative.

CONCLUSION(S)

Primary omental twin pregnancy is extremely rare, and when associated with acute abdomen and large hemoperitoneum, laparotomy is required for treatment.

Ectopic Pregnancy and Medical Abortion

OBJECTIVE

Medical abortion regimens have become more widely used to terminate early pregnancies. Medical abortion providers are concerned to diagnose and exclude women with ectopic pregnancy before initiating treatment, as with any early pregnancy termination. Yet, there is little information about whether the various pretreatment screening methods used are adequate. We reviewed published literature to determine the overall success of screening for ectopic pregnancy before medical abortion treatment.

DATA SOURCES

We searched MEDLINE for articles on medical abortion regimens published before July 2003.

METHODS OF STUDY SELECTION

We selected English language articles of studies of medical abortion with sample sizes greater than 100, which reported on ectopic pregnancy diagnosed after medical abortion treatment. Fifty-seven of 85 prospective studies and randomized trials (69%) met these inclusion criteria. We also included data from 2 unpublished studies because they were large and well-controlled and because they included serious adverse events known to us, which we did not deem fair to exclude from our analysis.

TABULATION, INTEGRATION, AND RESULTS

Each article was reviewed by one author. Data from selected studies were compiled, and the frequency of ectopic pregnancy diagnosed after medical abortion treatment was calculated. Ectopic pregnancy was diagnosed very infrequently following medical abortion procedures, occurring in only 10 of 44,789 (0.02%) women.

CONCLUSION

The very low frequency of ectopic pregnancies diagnosed after medical abortion treatment demonstrates that the various pretreatment screening methods that providers use to exclude patients with ectopic pregnancies are successful. Further, there is no evidence to suggest that medical abortion treatment leads to unusual complications for women with ectopic pregnancies.

Vital signs fail to correlate with hemoperitoneum from ruptured ectopic pregnancy

The objective was to determine correlation between vital signs and hemoperitoneum in ruptured ectopic pregnancy. A retrospective chart review of ectopic pregnancies at our urban county hospital between 1990 and 1998 was conducted. Fifty-one cases met inclusion criteria. Mean minimum systolic blood pressure (SBP) 89mmHg (range 40-118), mean maximum heart rate (HR) 101 beats/min (range 62-156). Mean volume of hemoperitoneum 1,050 mL (range 400-2,000 mL). Correlation between vital signs and volume of hemoperitoneum was poor (R(2) = 0.04 for HR, R(2) = 0.1 for SBP). Association of tachycardia with hypotension was also poor (R(2) = 0.1). Extreme individual variations were observed. If surgical decisions were made on the basis of hypotension, 38% of patients could have received either inappropriate additional studies or surgical approach. Patients with normal vital signs had a 20% chance of having class IV blood loss at surgery. HR and blood pressure do not correlate well with volumes of hemoperitoneum from ruptured ectopic pregnancy.

Uterine artery embolization for symptomatic uterine myomas

OBJECTIVE

To evaluate the role of uterine artery embolization as treatment for symptomatic uterine myomas.

DESIGN

Medline literature review, cross-reference of published data, and review of selected meeting abstracts.

RESULT(S)

Results from clinical series have shown a consistent short-term reduction in uterine size, subjective improvement in uterine bleeding, and reduced pain following treatment. Posttreatment hospitalization and recovery tend to be shorter after uterine artery embolization compared with hysterectomy. Randomized controlled trials have not been conducted, and long-term efficacy has not been studied. A limited number of deliveries have been reported following uterine artery embolization for uterine myomas.

CONCLUSION(S)

Uterine artery embolization is a unique new treatment for symptomatic uterine myomas. Even without controlled studies, demand for this procedure has increased rapidly. Uterine artery embolization may be considered an alternative to hysterectomy, or perhaps myomectomy, in well-selected cases. At the present time, however, uterine artery embolization should not be routinely recommended for women who desire future fertility.
