Ovarian Preservation and Recurrent Torsion in Children: Both Less Common Than We Thought

Contemporary Trends in Laparoscopy and Ovarian Sparing Surgery for Ovarian Torsion in the Pediatric Population

PURPOSE

Although total oophorectomy (TO) was historically performed in cases of nonviable-appearing ovaries, considerable evidence has demonstrated equivalent outcomes after ovarian sparing surgery (OSS) as well as long-term fertility preservation benefits. This study sought to compare outcomes of OSS and TO for patients with ovarian torsion.

METHODS

Females <21 years old admitted for ovarian torsion were identified from the Nationwide Readmissions Database (2016-2018) and stratified by OSS or TO. Propensity score-matched analysis (PSMA) utilizing >50 covariates (demographics, medical comorbidities, ovarian diagnoses, etc.) was constructed between those receiving TO and OSS.

RESULTS

There were 3,161 females (median 15 [12-18] years) with ovarian torsion, and concomitant pathologies included cysts (42%), benign masses (25%), and malignant masses (<1%). Open approaches were more common (52% vs. 48% laparoscopic), and ovarian resection (OSS or TO) was performed in 87% (39% OSS and 48% TO). OSS was more commonly performed with laparoscopic detorsions (60% vs. 40% TO), while TO was more frequent in open operations (59% vs. 41% TO; both p < 0.001). No differences in overall readmissions (7% OSS vs. 8% TO) or readmissions for recurrent torsion (<1% overall) and ovarian masses (<1%) were observed (both groups <1%; p = 0.612). After PSMA, laparoscopy was still utilized less frequently with TO (39% vs. 53%; p < 0.001) despite similar rates of malignant masses.

CONCLUSIONS

Overall, these data offer additional support for the current practice guidelines that give preference to OSS as the primary method of treatment for pediatric ovarian torsion in the majority of cases.

Hospital Volume and Quality of Care for Emergency Gynecologic Care

OBJECTIVE

To evaluate the association between hospital volume and the quality of gynecologic emergency care for tubal ectopic pregnancies, ovarian torsion, and pelvic inflammatory disease (PID).

METHODS

In this cross-sectional analysis, we analyzed patients who presented for emergency care for tubal ectopic pregnancies, ovarian torsion, and PID using the Premier Healthcare Database from 2006 to 2020. We measured the following outcomes: methotrexate use for ectopic pregnancy, ovarian cystectomy for torsion, and guideline-based antibiotic use for PID. For each condition, we measured outlier hospitals that performed the above interventions at below the 10th percentile. Multivariable logistic regression models were used to analyze associations between outlier care and hospital factors such as annualized mean case volume, urban or rural location, teaching status, bed capacity, and geographic region, as well as hospital-level patient population factors, including age, insurance status, and race.

RESULTS

A total of 602 hospitals treated patients with tubal ectopic pregnancies, of which 21.9% were outliers, with no cases managed with methotrexate. Of 512 hospitals treating patients with ovarian torsion, 17.4% were outliers, with no cases managed with cystectomy. Of 929 hospitals that treated patients with PID, 9.9% were deemed outliers with low rates of guideline-adherent antibiotic administration. Low-volume hospitals were more likely to be outliers with low rates of use of methotrexate for ectopic pregnancy (6.7% of high-volume hospitals vs 49.7% of low-volume hospitals were outliers; adjusted odds ratio [aOR] 0.13, 95% CI, 0.05-0.31 for high-volume hospitals) and cystectomy for torsion (34.9% of low-volume vs 2.4% of high-volume hospitals were outliers; aOR 0.05, 95% CI, 0.01-0.18 for high-volume hospitals). There was no association between hospital volume and lower rates of guideline-based antibiotic use for PID.

CONCLUSION

Higher hospital volume is associated with use of conservative, fertility-preserving treatment of emergency gynecologic conditions, including ectopic pregnancy and ovarian torsion.

Outcomes of Incidental Appendectomy During Ovarian Operations in a National Pediatric Cohort

INTRODUCTION

The utility of incidental appendectomy (IA) during many ovarian operations has not been evaluated in the pediatric population. This study sought to compare outcomes after ovarian surgery with IA in the pediatric population.

METHODS

Females (≤20 y old) undergoing ovarian surgeries (oophorectomy, detorsion and/or drainage) were identified from the Nationwide Readmissions Database (2016-2018). Those with appendicitis were excluded. A propensity score-matched analysis (PSMA) with 46 covariates (demographics, comorbidities, hospitalization factors, etc.) was performed between those receiving ovarian surgery with or without IA.

RESULTS

There were 13,202 females (median age 17 [IQR 14-20] y old) who underwent oophorectomy (90%), detorsion (26%), and/or ovarian drainage (13%). There were more episodes of torsion in the PSMA cohort receiving ovarian surgery alone (17% versus 10% IA; P = 0.016), while other indications (ovarian mass, cyst) were similar. Open (66% versus 34% laparoscopic) IAs were more frequent. Length of stay (LOS) was longer for those undergoing IA (3 [2-4] versus 2 [2-4] days ovarian surgery alone; P < 0.001). There was a higher rate of postoperative GI complications in the IA cohort. Subgroup analysis of those undergoing laparoscopic operations demonstrated no difference in LOS or postoperative complications between patients undergoing IA or not.

CONCLUSIONS

These data indicate that IA in pediatric ovarian operations is associated with longer LOS and higher GI postoperative complications. However, laparoscopic IA was not associated with higher cost, complications, LOS, or readmissions. This suggests that IA performed during ovarian surgeries in select patients may be cost-effective and worthy of future study.

Underutilization of laparoscopy for ovarian surgeries in the pediatric population: A nationwide analysis

PURPOSE

Oophorectomy and ovarian detorsion are some of the most frequent operations performed in the female pediatric population. Despite the advent of laparoscopy, many surgeons continue to utilize open surgical approaches in these patients. This study sought to compare nationwide trends and postoperative outcomes in laparoscopic and open ovarian operations in the pediatric population.

METHODS

Females less than 21 years old who underwent ovarian operations (oophorectomy, detorsion, and/or drainage) from 2016 to 2017 were identified from the Nationwide Readmissions Database. Patients were stratified by surgical approach (laparoscopic or open). Hospital characteristics and outcomes were compared using standard statistical tests.

RESULTS

There were 13,202 females (age 17 [14-20] years) who underwent open (59%) or laparoscopic (41%) ovarian operations. The most common indications for surgery were ovarian mass (48%), cyst (36%), and/or torsion (19%) for which oophorectomy (88%), detorsion (26%), and drainage (13%) were performed most frequently. The open approach was utilized more frequently for oophorectomy (95% vs. 77% laparoscopic) and detorsion (33% vs. 16% laparoscopic), both p < 0.001. A greater proportion of laparoscopic procedures were performed at large (67% vs. 61% open), teaching (82% vs. 76% open) hospitals in patients with private insurance (47% vs. 42% open), all p < 0.001. Patients undergoing open procedures had significantly higher index length of stay (LOS) and rates of wound infections. Thirty-day and overall readmission rates, as well as overall readmission costs, were higher in patients who received open surgeries.

CONCLUSIONS

Despite fewer overall complications, decreased cost, fewer readmissions, and shorter LOS, laparoscopic approaches are underutilized for pediatric ovarian procedures.

Diagnosis and Management of Pediatric Ovarian Torsion in the Emergency Department: Current Insights

Ovarian torsion is defined as twisting of the ovary around an axis consisting of its vascular pedicle, the infundibulopelvic ligament and the tubo-ovarian ligament, and can occur in females of any age. Torsion can be a result of ovarian mass causing asymmetry and subsequent torsion, or can be spontaneous. While ovarian torsion is a surgical emergency, early diagnosis and treatment can preserve ovarian viability even if necrosis is seen operatively. Presentation classically involves sudden onset severe abdominal pain and vomiting but diagnostic delay can follow subtler presentations. Diagnosis is most commonly based on sonographic findings, but advanced imaging such as CT or MRI may be required if sonography is not diagnostic. Treatment is surgical, with ovarian preservation preferred in almost all cases. In this review, I present the most recent evidence on epidemiology, diagnosis, and management of pediatric ovarian torsion, with a focus on point-of-care ultrasound for the emergency care provider.
