Expectant management of functional ovarian cysts: an alternative to hormonal therapy

Oral contraceptives for functional ovarian cysts

BACKGROUND

Functional ovarian cysts are a common gynecological problem among women of reproductive age worldwide. When large, persistent, or painful, these cysts may require operations, sometimes resulting in removal of the ovary. Since early oral contraceptives were associated with a reduced incidence of functional ovarian cysts, many clinicians inferred that birth control pills could be used to treat cysts as well. This became a common clinical practice in the early 1970s.

OBJECTIVES

This review examined all randomized controlled trials that studied oral contraceptives as therapy for functional ovarian cysts.

SEARCH METHODS

In March 2014, we searched the databases of CENTRAL, PubMed, EMBASE, and POPLINE, as well as clinical trials databases (ClinicalTrials.gov and ICTRP). We also examined the reference lists of articles. For the initial review, we wrote to authors of identified trials to seek articles we had missed.

SELECTION CRITERIA

We included randomized controlled trials in any language that included oral contraceptives used for treatment and not prevention of functional ovarian cysts. Criteria for diagnosis of cysts were those used by authors of trials.

DATA COLLECTION AND ANALYSIS

Two authors independently abstracted data from the articles. One entered the data into RevMan and a second verified accuracy of data entry. For dichotomous outcomes, we computed the Mantel-Haenszel odds ratio with 95% confidence interval (CI). For continuous outcomes, we calculated the mean difference with 95% CI.

MAIN RESULTS

We identified eight randomized controlled trials from four countries; the studies included a total of 686 women. Treatment with combined oral contraceptives did not hasten resolution of functional ovarian cysts in any trial. This held true for cysts that occurred spontaneously as well as those that developed after ovulation induction. Most cysts resolved without treatment within a few cycles; persistent cysts tended to be pathological (e.g., endometrioma or para-ovarian cyst) and not physiological.

AUTHORS' CONCLUSIONS

Although widely used for treating functional ovarian cysts, combined oral contraceptives appear to be of no benefit. Watchful waiting for two or three cycles is appropriate. Should cysts persist, surgical management is often indicated.

DATA COLLECTION AND ANALYSIS

Two authors independently abstracted data from the articles. One entered the data into RevMan and a second verified accuracy of data entry. For dichotomous outcomes, we used Peto odds ratios with 95% confidence intervals (CI). For continuous outcomes, we calculated mean differences with 95% CI.

MAIN RESULTS

We identified seven randomized controlled trials from four countries; the studies included a total of 500 women. Treatment with combined oral contraceptives did not hasten resolution of functional ovarian cysts in any trial. This held true for cysts that occurred spontaneously as well as those that developed after ovulation induction. Most cysts resolved without treatment within a few cycles; persistent cysts tended to be pathological (e.g., endometrioma or para-ovarian cyst) and not physiological.

SEARCH STRATEGY

We searched the computer databases of CENTRAL, PubMed, POPLINE, and EMBASE for randomized controlled trials. We also examined the reference lists of articles and wrote to authors of all studies identified to seek articles we had missed.

SELECTION CRITERIA

We included randomized controlled trials in any language that included oral contraceptives used for treatment and not prevention of functional ovarian cysts. Criteria for diagnosis of cysts were those used by authors of studies.

DATA COLLECTION AND ANALYSIS

Two authors independently abstracted data from the articles and entered them into RevMan 4.2. We used Peto odds ratios with 95% confidence intervals for dichotomous outcomes.

MAIN RESULTS

We identified four randomized controlled trials from three countries; the studies included a total of 227 women. Treatment with combined oral contraceptives did not hasten resolution of functional ovarian cysts in any trial. This held true for cysts that occurred spontaneously as well as those that developed after ovulation induction. Most cysts resolved without treatment within a few cycles; persistent cysts tended to be pathological (e.g., endometrioma or para-ovarian cyst) and not physiological.

AUTHORS' CONCLUSIONS

Although widely used for treating functional ovarian cysts, combined oral contraceptives appear to be of no benefit. Watchful waiting over several cycles is appropriate. Should cysts persist, surgical management is often indicated.

Laparoscopic management of ovarian cysts

The role of operative laparoscopy in the management of patients with adnexal masses is expanding, offering distinct advantages of lower morbidity, improved postoperative recovery, and reduced cost. Although clinical examination and the results of preoperative work-up often indicate the benign or malignant nature of the cyst, only histology can provide the absolute diagnosis. Advanced operative laparoscopy for management of ovarian cysts, when performed by experienced endoscopic surgeons, is as safe and effective as open techniques.

Functional ovarian cysts and the need to remove them

OBJECTIVE

To review the need for the removal of functional ovarian cysts.

MATERIALS AND METHODS

Over a 5-year period, between July 1994 and June 1999, all functional ovarian cysts files were reviewed in order to determine the main surgical indication.

RESULTS

Thirty-four functional ovarian cysts (11.45%) were removed during that period. In 14 cases, the surgical operation was considered justified. In 32 cases, the cysts were not organic as supposed to be and had no reason to be removed.

DISCUSSION

Reported functional ovarian cyst removal rates range from 15 to 30%. Present exploration means (particularly ultrasound-guided needle aspiration) does not permit to discriminate functional from organic cysts in more than 70% of the cases.

CONCLUSION

It is impossible to reduce functional cyst removal rate to 0% but we should all evaluate our activity yearly and be able to limit this rate to less than 30%.

Evaluation of adnexal masses in adolescents

The detection of adnexal masses in adolescents is worrisome to patients, their families, and physicians. Reassurance can be given that the vast majority of these lesions are benign. Furthermore, a significant fraction of benign masses are functional ovarian cysts, most of which resolve spontaneously and never need surgery. Imaging is critical in determining the management of these patients. Sonography is the preferred first-line diagnostic tool. When surgery is necessary, physicians must recognize the importance of conserving the ovaries and uterus to avoid the loss of reproductive and endocrine function.

Ovarian cysts in the pediatric population

With the widespread availability and use of pelvic sonography, the rate at which ovarian cysts are detected in the pediatric population has increased, and such cysts are an important problem encountered in pediatric surgical practice. Rational management should take into account key factors such as symptoms, patient age, menarchal status, cysts size, and character, as well as associated medical conditions. The purpose of this review is to discuss the incidence and pathophysiology of ovarian cysts in children. A management strategy is presented based on the above-mentioned key factors.
