Torsion of the uterine adnexa. Pathologic correlations and current management trends.
OBJECTIVE
To evaluate the clinical and pathologic correlates of specimens removed for the diagnosis of adnexal torsion and to evaluate trends in the management of torsion.


METHODS
Cases of ovarian or adnexal torsion (N = 104) were identified retrospectively over a period extending from January 1987 to March 1998 by the coding of ovarian, fallopian tube or adnexal torsion. Statistical evaluation was by chi 2 analysis using the Bonferroni inequality correction when appropriate.


RESULTS
Neoplastic and functional tumors of the ovary composed > 90% of the diagnoses at microscopic evaluation, with cancer diagnosed in < 1% of cases. Laparoscopy was attempted in 47 (46%) cases, and adnexasparing procedures were performed in 20 (19%) patients. Patients treated in the latter half of the study were not less likely to undergo laparotomy than those treated in the first half; however, conversion from laparoscopy to laparotomy was significantly less common in the latter half. Patients in this study were more likely to receive an adnexa-sparing operation than historical controls, but there was no improvement in this rate from the first to the second half of this study. A history of previous abdominal surgery was the most common associated condition, but 47% of patients had no known risk factors. Ovarian hyperstimulation, previously omitted in series reports, was an antecedent factor in 9% of patients.


CONCLUSIONS
Adnexal torsion is most commonly associated with a benign process. A more-conservative approach to the treatment of this process is becoming increasingly common, as seems warranted in light of the low incidence of malignancy. The need for conversion from a laparoscopic to an open approach appears to have been waning over the last decade; that may correlate with an increased comfort level in gynecologists with laparoscopic approaches.
