Ovarian cysts in infants and children

Retrospective Review of Management of Antenatally Diagnosed Ovarian Cysts at the Hospital for Sick Children

INTRODUCTION

Postnatal management of antenatally diagnosed ovarian cysts is not well-defined. The clinical course, management, and outcomes of patients with antenatally diagnosed ovarian cysts were reviewed.

METHODS

Infants <1 year of age with antenatally diagnosed ovarian cyst managed at The Hospital for Sick Children between January 2017 and December 2021 were included. Patient charts were reviewed for postnatal ultrasound (US) images, management, clinical course and complications. Mixed linear regression analysis was used to model the change in cyst size over time.

RESULTS

In total, 52 patients were included and 10 patients had no cyst identified at their first postnatal US. Of the remaining cases, 36% were simple/physiologic and 64% had complex features. Two underwent percutaneous aspiration while 40 patients were managed expectantly with most cysts (62%) resolving. The rate of resolution was significantly higher and faster for simple compared to complex cysts (84% versus 52%, p < 0.05). Cysts that persisted at the end of the study period (n = 14) had all decreased in size, with a rate of resolution similar to resolved cysts. Only one patient managed expectantly required urgent laparoscopy for salpingoophorectomy.

CONCLUSION

Antenatally diagnosed ovarian cysts exhibit high rates of resolution with expectant management, supporting the safety and efficacy for expectant management for these patients.

Ovarian tumors in the pediatric population: An update

Research reveals that 1% of neoplasms in females under 17 years of age are ovarian neoplasms and though usually benign, malignant tumors may occur in the pediatric age group. This review considers various current concepts of these tumors including the epidemiology, risk factors, clinical presentations, diagnosis, differential diagnosis, and treatment options including the need to provide fertility-sparing surgery as well as their potential impacts on the psychological well-being of children and adolescents. We gathered data from the published articles ranging from studies, meta-analyses, retrospective studies, and reviews. We focused on the articles published in English between January 1, 2000, and August 31, 2023. Only a few articles published prior to 2000 were included for historical perspective.

Managing Fetal Ovarian Cysts: Clinical Experience with a Rare Disorder

Background and Objectives: Fetal ovarian cysts (FOCs) are a very rare pathology that can be associated with maternal-fetal and neonatal complications. The aim of this study was to assess the influence of ultrasound characteristics on FOC evolution and therapeutic management. Materials and Methods: We included cases admitted to our perinatal tertiary center between August 2016 and December 2022 with a prenatal or postnatal ultrasound evaluation indicative of FOC. We retrospectively analyzed the pre- and postnatal medical records, sonographic findings, operation protocols, and pathology reports. Results: This study investigated 20 cases of FOCs, of which 17 (85%) were diagnosed prenatally and 3 (15%) postnatally. The mean size of prenatally diagnosed ovarian cysts was 34.64 ± 12.53 mm for simple ovarian cysts and 55.16 ± 21.01 mm for complex ovarian cysts (p = 0.01). The simple FOCs ≤ 4 cm underwent resorption (n = 7, 70%) or size reduction (n = 3, 30%) without complications. Only 1 simple FOC greater than 4 cm reduced its size during follow-up, while 2 cases (66.6%) were complicated with ovarian torsion. Complex ovarian cysts diagnosed prenatally underwent resorption in only 1 case (25%), reduced in size in 1 case (25%), and were complicated with ovarian torsion in 2 cases (50%). Moreover, 2 simple (66.6%) and 1 complex (33.3%) fetal ovarian cysts were postnatally diagnosed. All of these simple ovarian cysts had a maximum diameter of ≤4 cm, and all of them underwent size reduction. The complex ovarian cyst of 4 cm underwent resorption during follow-up. Conclusions: Symptomatic neonatal ovarian cysts, as well as those that grow in size during sonographic follow-up, are in danger of ovarian torsion and should be operated on. Complex cysts and large cysts (with >4 cm diameter) could be followed up unless they become symptomatic or increase in dimensions during serial ultrasounds.

Minimally invasive adnexa-sparing surgery for benign ovarian and paratubal masses in children

BACKGROUND

The precision of minimally invasive surgery (MIS) to resect benign ovarian and paratubal masses while preserving adnexa in children is unclear. This study evaluated the integrity of laparoscopy to spare adnexa while resecting benign pathologies in children.

METHODS

The institutional pathology database was queried to identify patients aged 18 years and younger having any ovarian or tubal lesion resected at a comprehensive children's hospital between 2006 and 2021. Adnexa-sparing surgery was defined as preserving both the ovary and tube from which the lesion was resected. Postoperative ultrasounds were reviewed to document ovarian follicles, blood flow, volumes, and lesion recurrence.

RESULTS

Adnexal preservation was implemented in 168 of 328 pathological resections. MIS approach was used in 149 cases. Median age was 13.4 [11.0-15.3]. Among sparing surgeries, MIS associated with benign pathology, shorter operative time (median minutes: 78 MIS [59-111.5]; 130 open [92.8-149.8]; 174 MIS-to-open [132.8-199.5]; p = 0.010), and reduced hospital stay (median days: 1 MIS (Lindfors, 1971; Lovvorn III et al., 1998) [1-2]; 2 open [2-2.9], 2 MIS-to-open [1-3.3]; p = 0.001). Postoperative ovarian volume ipsilateral to the MIS procedure (median, 7.6 ml [4.3-12.1]) was relatively smaller than the contralateral ovary (median, 9.1 ml [5.5-15.0]). Blood flow was documented to the ovary in 70/94 (74.4%) of patients after MIS adnexal-sparing surgery. Distinct follicles were detected in 48/74 (64.8%) of post-menarchal patients after MIS adnexal-sparing surgery. Five ovarian cysts recurred.

CONCLUSIONS

MIS preserves adnexa reliably, with postoperative ovarian follicles and blood flow detected in most patients, and maintains ∼80% of contralateral volume, while achieving definitive tumor resection.

Characteristics of ovarian necrosis in the neonatal ovarian tumor: a single-center retrospective study and review of literature

To analyze the characteristics of ovarian necrosis in the neonatal ovarian tumor, and review treatments for ovarian torsion in neonates. Neonates with ovarian tumors undergoing surgery in Fujian Maternal and Child Health Hospital (Fujian Children's Hospital) from February 2016 to August 2021 were analyzed retrospectively. Patients were divided into the ovarian necrosis group and control group (without necrosis). Demographic characteristics, prenatal and postnatal examination, operation, and pathological findings were compared and the relevant factors of ovarian necrosis were discussed. 26 neonates were included, 12 in necrosis group and 14 in control group. The maximum diameter of the tumor in necrosis group was smaller than that in control group (P < 0.01). The preoperative CRP in necrosis group was significantly higher than that in control group (P < 0.05). There were no significant differences between two groups in the timeliness of surgery, pathological types, and length of postoperative hospital stay. About 26% of neonatal ovarian torsion could be rescued. Neonatal ovarian necrosis is characterized by a smaller tumor size and a higher preoperative CRP level. Timely surgery after birth might not change the ovarian outcome, but ovarian detorsion could be attempted in neonates to save residual ovarian function.

Laparoscopy ıs a defınıtıve dıagnostıc method for auto-amputated ovary ın ınfants

PURPOSE

Antenatal auto-amputation of the ovary is an extremely rare event, and its diagnosis is difficult. We aimed to retrospectively review the cases with antenatal auto-amputation, where the diagnosis was made based on detection of free-floating cyst during surgery.

METHODS

Patients diagnosed with auto-amputated ovary during the surgery between 2012 and 2021 were included in the study. The data were reviewed retrospectively. Clinical, radiological, surgical, and histopathological findings were recorded.

RESULTS

Eight patients underwent surgery for an abdominal cystic mass. The age range of patients who were operated was from 21 days to 9 months. None of the patients had symptoms, except one patient who had a large cyst and was vomiting. Prenatal ultrasound examination indicated an intra-abdominal cyst in all patients, but auto-amputated ovary diagnosis was not made. Differential postnatal diagnoses included an ovarian cyst, ovarian teratoma, tuba-ovarian torsion, mesenteric lymphatic malformation, and intestinal duplication cyst. Only one patient had an auto-amputated ovary suspicion in computed tomography. Laparoscopic exploration (n: 7) or laparotomy (n: 1) was performed. Histopathologic examination was necrosis and calcification (n: 6), necrosis (n: 1), and serous cystadenoma and necrosis (n: 1).

CONCLUSION

We suggest that laparoscopy should be used for diagnosis and treatment of antenatal intra-abdominal cysts that persist postnatally because of diagnostic dilemmas. We recommend in patients diagnosed with auto-amputated ovary that the other ovary should be carefully monitored and followed up in terms of ovarian cyst, due to the possible risk of torsion.

Pediatric and Adolescent Gynecologic Emergencies

Diagnosis of gynecologic emergencies in the pediatric and adolescent population requires a high index of suspicion to avoid delayed or incorrect diagnoses. This article aims to dispel common misunderstandings and aid with diagnosis and management of 3 common pediatric and adolescent gynecologic emergencies: adnexal torsion, vulvovaginal lacerations, and nonsexually acquired genital ulcers.

Review of a 25-Year Experience in the Management of Ovarian Masses in Neonates, Children and Adolescents: From Laparoscopy to Robotics and Indocyanine Green Fluorescence Technology

Background: Ovarian masses in pediatric populations are the most common abdominal masses in young girls. In neonates, the majority of masses are benign while in children and teen-agers the risk of malignancy exists. The aim of this study is to perform a 25-year experience retrospective analysis of clinical and therapeutic aspects of ovarian tumors in girls, in order to show how the development of minimally invasive technology has changed the management of this pathology. Methods: The records of patients under the age of 18 who were operated in three pediatric surgical units due to ovarian mass, in the last 25 years, were reviewed retrospectively. The study group comprised 147 patients operated between 1996 and 2021 with a diagnosis of ovarian masses. Data involved were demographical, surgical, follow-up and final diagnosis. We analyzed the type of surgical technique, intra-operative data (operative time, the use of different technologies), complications, length of stay and long-term follow-up. Based on these data, we assessed how the surgical approach to ovarian masses has changed in the last 25 years in newborns and young girls. Results: The patients ages ranged between 7 days and 15 years (median, 59 days). All the procedures were completed in laparoscopy or robotics without conversion in open surgery. One-hundred and eleven patients were neonates; they all had follicular cysts and they were all managed in laparoscopy using 1 or 3 trocars. In 80/111 patients (72%), a small part of ovarian parenchyma was saved; in 31/111 patients (28%), in which the ovarian parenchyma was not available, an ovariectomy was performed. Patients in which we saved a small part of ovary, at long term follow-up (minimum follow-up of 12 years) (29/80, 36%), developed a normal ovary at US control. Thirty-six were older patients. They had a histological diagnosis of benign (30) or malign (6) tumors. All the patients (8/36) with a pre-operative suspicion of ovarian malignancy received an ovariectomy and an adnexectomy using sealing devices. In the last 10 years in all the children, except neonates, we adopted sealing devices and, in the last 4 years, in 20 cases, we always adopted ICG fluorescence technology to check ovarian vascularization in case of torsion or to check lympho-nodes condition in case of malignancy. Conclusions: In neonatal ovarian cysts, surgical management remained unchanged and an ovarian sparing procedure is always indicated and the long-term follow-ups confirm this hypothesis. The principal innovation in this age period is the use of ICG fluorescence technology to check ovarian vascularization in case of torsion. In teenagers, the decision-making strategy is based on the tumoral markers and on the morphological aspects of the mass. Robotics cystectomy or ovariectomy now-days represents the safer and faster way to perform this. Sealing devices are essential tools for dissection and resection to avoid bleeding. ICG fluorescence technology in all ages is fundamental to check ovary vascularization after detorsion or to check lympho-node status in case of malignancy. All the suspected lesions have to be removed with an endo-bag.

The Role of Surgery in Antenatal Ovarian Torsion: Retrospective Evaluation of 28 Cases and Review of the Literature

STUDY OBJECTIVE

Antenatal ovarian torsion (AOT) is rare and requires differentiating from other congenital cystic masses of the abdomen and pelvis in neonates. In this study, it was aimed to evaluate the prenatal characteristics and postnatal outcomes of AOT. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Hospital records of patients (n = 28) with diagnosis of AOT between 2004 and 2020 were reviewed and their prenatal characteristics, postnatal examination, imaging, operative, and histopathological findings were evaluated.

RESULTS

There were 28 patients during the study period. In most of the patients (25/28; 89.3%) AOTs were detected prenatally. All were term babies with a mean birth weight of 3010 ± 466.6 g. Mean maternal age was 25.75 ± 3.65 years. Prenatal history was event-free in all and none had additional anomalies. Physical examination revealed mobile intra-abdominal cystic lesions in 16 (57.1%) patients. AOTs mimicked other pathologies as intestinal duplication cyst or mesenteric cyst (n = 7), complex ovarian cyst (n = 3), mature cystic teratoma (n = 3), simple renal cyst (n = 1), and ectopic kidney (n = 1) in 15 (53.6%) patients in postnatal ultrasonography. Elective laparoscopic surgery was performed in 26 (92.8%) patients. The other 2 patients required emergency open surgery because of acute symptoms. Ovaries were autoamputated in 17 (60.7%) patients. Histopathological examination revealed necrosis and dystrophic calcification in all specimens. There was neoplastic involvement in 2 patients (serous cystadenoma and gonadoblastoma). No complication occurred in the early follow-up period (mean: 73.9 ± 46.8 months).

CONCLUSION

AOTs can be detected easily during the antenatal period. Neoplastic involvement with AOTs is rare but possible. Although AOTs might mimic other cystic pathologies, it should be one of the first diagnoses to be considered, in the presence of a palpable intra-abdominal mass and complex cystic lesion in infant girls. It can be efficiently and safely managed using minimally invasive techniques.

Symptomatic Persistent Fetal Ovarian Cysts

ABSTRACT

Vomiting in young infants is a common presentation to the pediatric emergency department with a broad differential diagnosis. We present 2 cases seen in our emergency department of infant females with symptomatic complex ovarian cysts who presented with vomiting. The first case study describes a patient with a prenatally diagnosed ovarian cyst that was being followed with serial ultrasounds by general surgery. The second case study describes a patient with reportedly normal prenatal ultrasounds with a subsequent diagnosis of a large complex ovarian cyst. These cases were selected to review pertinent imaging findings, discuss management decisions, and expand the differential of vomiting in the young female infants.

Missed opportunities for ovarian salvage in children: an 8-year review of surgically managed ovarian lesions at a tertiary pediatric surgery centre

INTRODUCTION

The aetiology and management of ovarian pathology in children differs between antenatal and postnatal lesions. However, all lesions may present acutely due to adnexal torsion. In this setting, opportunities to preserve fertility with ovary-sparing surgery (OSS) may be missed. Some studies suggest that pediatric and adolescent gynaecology (PAG) input in care is associated with OSS.

METHODS

A retrospective cohort study of children undergoing surgery for ovarian pathology at a tertiary pediatric surgery centre over an 8-year period (2011-2018). Patient factors, lesion characteristics and PAG involvement were examined for association with OSS using multivariate logistic regression.

RESULTS

Thirty-five patients with ovarian pathology managed surgically were included. Ten were infants with lesions detected antenatally; all were managed by pediatric surgeons (PS) alone at median age 2 weeks (1 day-25 weeks). Twenty-five patients presented postnatally at median age 11 (0.75-15) years. In total, there were 16 cases of adnexal torsion, each managed primarily by PS. Twelve underwent oophorectomy and six (50%) of these cases had viable ovarian tissue on histology. Furthermore, two infants with large simple cysts were similarly managed by unnecessary oophorectomy based on histology. Overall rate of OSS was 46% and PAG involvement was the only factor associated with ovarian salvage.

CONCLUSION

Differences in surgical management between PAGs and PS may be attributable to the different patient populations they serve. We recommend improving the knowledge of PS trainees in OSS approaches for adnexal torsion and large benign lesions.

Ovarian lesions and tumors in infants and older children

Objectives

Ovarian lesions are rare but frequent in children. Patients could present with abdominal pain, but ovarian lesions could also be incidentally found on ultrasound. Awareness is required in cases with acute, severe lower abdominal pain, as ovarian torsion could be the cause. Other lesions can be cysts or benign or malignant ovarian tumors. Thus, the aim of this paper is to review typical ovarian lesions according to age, imaging and laboratory findings, and surgical management.

Methods

We retrospectively analysed the patient charts of 39 patients aged 10.4 ± 6.1 years (from 3 months to 18 years) with ovarian lesions treated in our institution between 01/2009 and 08/2020. All clinical and pathological findings of infants and children operated on for ovarian lesions were included.

Results

Ovarian lesions in children younger than 2 years of age were typically ovarian cysts, and ovarian tumors were not observed in this age group. In older children over 10 years of age, tumors were more common – with mostly teratoma or other germ cell tumors, followed by epithelial tumors. Moreover, acute or chronic ovarian torsion was observed in all age groups. In general, ovarian tumors were much larger in size than ovarian cysts or twisted ovaries and eventually showed tumor marker expression of AFP or ß-HCG. Simple ovarian cysts or twisted ovaries were smaller in size. Surgery for all ovarian lesions should aim to preserve healthy ovarian tissue by performing partial ovariectomy.

Conclusions

In adolescent girls with acute abdominal pain, immediate laparoscopy should be performed to rule out ovarian torsion. Careful imaging evaluation and the assessment of tumor markers should be performed in painless ovarian lesions to indicate an adequate surgical ovarian-sparing approach.

Imaging Appearance of Nongerminoma Pediatric Ovarian Germ Cell Tumors Does Not Discriminate Benign from Malignant Histology

STUDY OBJECTIVE

Pediatric ovarian neoplasms with imaging appearance suggestive of teratoma are often presumed to have low risk of malignancy. We assessed the pre-operative imaging appearance of pediatric malignant ovarian germ cell tumors (MOGCT) and the presence of associated teratoma in a series of MOGCT.

DESIGN

Retrospective review of clinical and pathology data.

SETTING

Multicenter trial for extracranial malignant germ cell tumors in young female individuals by the Children's Oncology Group (COG study AGCT0132) that included yolk sac tumor, embryonal carcinoma and choriocarcinoma.

PARTICIPANTS

Female individuals 0-20 years of age at enrollment with ovarian primary nonseminomatous malignant germ cell tumors.

INTERVENTIONS

Review of data forms, including prospectively collected surgical checklist documenting imaging characteristics of the tumor, and review of pathology reports.

MAIN OUTCOME MEASURES

Description of imaging appearance and frequency of mixed histology with benign teratoma elements.

RESULTS

A total of 138 female individuals (11 months to 20 years of age) had primary ovarian tumors. Imaging appearance and pathology information were available for 133 patients. Among the 133 patients, tumor appearance was solid (10.5%), solid with calcification (3.0%), mixed cystic and solid (58.7%), mixed cystic and solid with calcification (24.8%), and unknown (3.0%). In all, 54% had elements of teratoma in addition to malignant histology.

CONCLUSION

Mixed cystic and solid appearance with or without calcification was seen in 83.5% of pediatric ovarian malignant germ cell tumors. Associated benign teratoma was common. The presence of a mixed cystic and solid appearance on preoperative imaging should not dissuade the surgeon from obtaining preoperative serum markers and undertaking complete surgical staging.

Fetal abdominal tumors and cysts

This article reviews the contemporary diagnosis and management of the most common abdominal neoplasms and cystic lesions diagnosed in the fetus. Fetal tumors discussed include teratomas (sacrococcygeal, cervical or mediastinal), mesoblastic nephroma, nephroblastoma (Wilms' tumor), neuroblastoma, and hepatoblastoma. Fetal abdominal cystic lesions discussed include ovarian cyst, choledochal cyst, intestinal duplication cyst, mesenteric cyst, simple hepatic cyst, and meconium pseudocyst. We discuss the rare indications for fetal intervention or fetal surgery and other perinatal management, including prenatal interventions and fetal surgery for sacrococcygeal teratoma. The lesions reviewed are detected by widespread use of screening ultrasonography during pregnancy. Work-up for these abnormalities may include fetal MRI which enhances the diagnostic accuracy of abdominal tumors and cystic lesions and can aid in characterization of the lesion in relationship to surrounding anatomic structures. Accurate prenatal diagnosis of such lesions permits recommendations for optimal location and timing of delivery, and inclusion of appropriate caregivers and expertise to facilitate postnatal management. Perinatal management of the fetus with a neoplasm requires consideration of the optimal timing and mode of delivery, and pediatric oncology and surgical specialty care. The majority of tumors diagnosed antenatally have good prognosis with current multimodality treatment.

Gynecological Problems in Newborns and Infants

Pediatric-adolescent or developmental gynecology has been separated from general gynecology because of the unique issues that affect the development and anatomy of growing girls and young women. It deals with patients from the neonatal period until maturity. There are not many gynecological problems that can be diagnosed in newborns; however, some are typical of the neonatal period. This paper aims to discuss the most frequent gynecological issues in the neonatal period.

Imaging of Acute Abdominal Pain in the Pediatric Population

Acute abdominal pain is a common complaint in pediatrics. Although age and location of pain can help focus differential diagnosis, imaging plays an essential role in clinical evaluation. In this review, we discuss the optimal imaging approach to pediatric patients with acute abdominal pain and important imaging findings in the most common causes of abdominal pain in the pediatric population. [Pediatr Ann. 2020;49(9):e380-e388.].

Ovarian torsion in utero diagnosed at 37 weeks of pregnancy: A case report

Background

Fetal ovarian masses are common abdominal anomalies in female fetuses, often diagnosed in the third trimester. Most masses are benign and tend to resolve spontaneously within a few months after birth, but larger masses may present complications such as torsion.

Case

A 21-year-old primagravid woman was noted to have a complex avascular solid mass in the fetal left pelvis, which was consistent with complex fetal left ovarian torsion. The patient underwent induction of labor at 39 weeks for possible intervention. The infant underwent surgery at 5 weeks of age and a torsed, necrotic ovary was discovered.

Conclusion

The diagnosis of ovarian torsion in utero is rare, and prenatal and postnatal guidelines are needed on frequency of monitoring, timing of delivery, and postnatal follow-up.

•

Diagnosis of ovarian torsion antenatal is rare.

•

Counseling is a balance of the risk-benefit of timing of delivery and surgical intervention.

•

How long an ovary has been torsed is unpredictable, aggressive management may not be optimal.

•

Multidisciplinary planning is beneficial for postnatal counseling and management.

•

More research is necessary for optimal timing of delivery in cases of in-utero ovarian torsion.

Imaging in pediatric ovarian tumors

The spectrum of ovarian tumors in the pediatric population differs significantly from that in adults. Germ cell tumors are the predominant class of ovarian tumors in children, whereas epithelial tumors are the most common in adults. Ultrasonography is the modality of choice for the initial evaluation of pediatric ovarian tumors. Determining the diagnosis based on imaging may prove difficult, and combining the imaging findings with the clinical scenario is very helpful in reaching a differential diagnosis during clinical practice. We will discuss the spectrum of ovarian neoplasms in the pediatric population and describe their clinical, pathologic, and imaging characteristics. A few unique entities related to ovarian tumors, such as growing teratoma syndrome, anti-N-methyl-D-aspartate receptor encephalitis, and hereditary ovarian tumor syndromes, are also discussed. In addition, we will review several entities that may mimic ovarian neoplasms as well as their distinct imaging features.

Effect of Surgical Specialty on Management of Adnexal Masses in Children and Adolescents: An 8-Year Single-Center Review

STUDY OBJECTIVE

Children with adnexal masses might be managed by pediatric surgeons, urologists or gynecologists, with the potential for different management strategies between specialties. In this study we compared ovarian conservation rates and surgical approach for adnexal masses in children and adolescents managed either by pediatric surgeons/urologists or gynecologists at a tertiary care institution.

DESIGN

Retrospective cohort review.

SETTING

Tertiary pediatric and adult university hospital.

PARTICIPANTS

Patients younger than 18 years of age with an adnexal mass managed surgically with removal of histologically confirmed ovarian or fallopian tube tissue from 2008 to 2015.

INTERVENTIONS

Laparoscopic or open procedure for adnexal mass.

MAIN OUTCOME MEASURES

The primary outcome was rate of ovarian conservation relative to surgical specialty. The secondary outcome was surgical approach relative to surgical specialty.

RESULTS

Forty-eight patients underwent surgery for adnexal masses; 26 (54%) under pediatric surgery/urology and 22 (46%) under gynecology care. Laparoscopy was performed in 5 (19%) pediatric and 19 (86%) gynecology cases (P = .000006). Of 24 patients older than 12 years of age with a benign tumor, 10 (42%) underwent procedures resulting in loss of an ovary with or without fallopian tube; 8 of these (80%) were under pediatric care. Of the remaining 14 (58%) who underwent ovarian conserving surgery, 12 (80%) were under gynecology care (P = .0027).

CONCLUSION

Patients with a benign tumor were significantly more likely to undergo ovary-preserving surgery under gynecology care than under pediatric surgery/urology care. A multidisciplinary team approach involving gynecology and pediatric surgical specialties would be valuable in assessing the merits of ablative or conservative surgery in each case.

Surgically treated ovarian lesions in preadolescent girls

INTRODUCTION

The purpose of this study was to investigate the epidemiology and characteristics of surgically treated ovarian lesions in preadolescent girls.

MATERIAL AND METHODS

This was a retrospective cohort study including all 0- to 11-year-old girls operated at a single center from 1999 to 2016 for ovarian cysts, neoplasms or torsions. Patient charts were reviewed for symptoms, preoperative radiological imaging, operative details and histopathology.

RESULTS

We identified 78 girls, resulting in a population-based incidence of 4.2/100 000. Infants (n = 44) presented with benign cysts (42/44, 95%, one bilateral), a benign neoplasm (1/44, 2%) and a torsion without other pathology (1/44, 2%). Torsion was found in 25/29 (86%) ovaries with complex cysts and in 3/15 (21%) ovaries with simple cysts in preoperative imaging (P < 0.001). Most infants were symptomless. Lesions in 1- to 11-year-old girls (n = 34) included benign neoplasms (n = 21/34, 62%), malignant neoplasms (n = 5/34, 15%), a cyst with torsion (n = 1/34, 3%) and torsions without other pathology (n = 7/34, 21%). Torsion was more common in benign (17/21, 81%) than in malignant neoplasms (1/5, 20%) (P < 0.020). Ovarian diameter did not differ between ovaries with or without torsion (P = 0.238) or between benign and malignant neoplasms (P = 0.293). The duration of symptoms in lesions with or without torsion was similar.

CONCLUSIONS

The majority of surgically treated ovarian lesions in preadolescent are benign lesions with torsion. Surgery should be ovary-preserving and performed without delay.

Management of ovarian lesions diagnosed during infancy

PURPOSE

Prior studies of infant ovarian cysts have recommended intervention for those larger than 4 cm. We reviewed the natural history and features of those managed operatively versus nonoperatively.

METHODS

A retrospective study was performed of ovarian lesions in children <1 year-old from 2000 to 2014.

RESULTS

Forty patients were identified. Twenty-eight (70%) underwent operative management, while 12 (30%) were managed conservatively, including one undergoing aspiration. The mean age at surgery was 125 days. All but one patient (96%) had evidence of antenatal torsion intraoperatively or on final pathology. All resected lesions were benign. Ultrasound findings more common in those undergoing surgery included intracystic debris (p < 0.001), fluid-fluid or fluid-debris levels (p = 0.002), absence of Doppler flow (p = 0.014), solid components (p = 0.04), and calcifications (p = 0.001). Cysts managed nonoperatively had an average diameter of 2.5 cm, compared to 5.1 cm in the operative group (p < 0.001). Three of the lesions managed nonoperatively had a diameter greater than 3.5 cm (mean 5.1 cm) and were followed for an average of 153 days until resolution.

CONCLUSIONS

The majority of infant ovarian lesions were excised, although none were malignant. Aspiration or observation of larger cysts was feasible and safe. Ovarian cysts in this age group should be considered for nonoperative management and closely followed.

Case Report of Clitoral Hypertrophy in 2 Extremely Premature Girls With an Ovarian Cyst

Neonatal clitoromegaly is mainly attributed to in utero androgen exposure secondary to congenital adrenal hyperplasia. We report on 2 extremely premature girls with clitoromegaly, increased androgen levels, no salt wasting syndrome, and ovarian cyst. In case 1, the cyst liquid was aspired during ovarian hernia surgery and revealed high androgen levels. After aspiration, serum androgen levels decreased, as did clitoral size. In case 2, an ovarian cyst was seen on pelvic ultrasound. Aspiration was not indicated. The cyst regressed spontaneously on iterative pelvic ultrasounds, and her clitoromegaly decreased. Case 1 demonstrates the ovarian origin of this transient virilization. Cyst formation seems to be linked to the physiologic maturation of the hypothalamic-pituitary-ovarian axis. Thirteen cases of clitoromegaly with hyperandrogenism, without salt wasting syndrome, have been reported in extremely premature infants. In the context of clitoromegaly, we recommend ruling out in utero androgen exposure, adrenal hyperandrogenism, and disorders of sex development. We further recommend affirming hyperandrogenism by androgen assay and confirming ovarian origin with gonadotrophin assays and pelvic ultrasound. Drug therapy abstention and clinical and ultrasound monitoring are recommended because spontaneous regression of clitoral hypertrophy seems to be the most common outcome in the literature, as it was in our 2 observations.

Ovarian torsion in children: Development of a predictive score

The aim of this study was to identify clinical signs and symptoms of ovarian torsion (OT) in children and to develop a simple predictive score.A chart review of patients with acute adnexal pathologies treated at the University Children's Hospital Basel, Switzerland, between March 2006 and June 2015 was performed. Medical records were screened for demographic and clinical data. These included clinical symptoms, laboratory studies, imaging, and type of treatment. The diagnosis OT was defined as intraoperative visualization of the torsed ovary around its pedicle at least 360 degrees. Variables predictive for OT were identified and the following score for the likelihood of having OT was developed: age (points = number of years) minus 3 points (if vomitus = "yes") and plus 1 point (if "pain duration >12 hours").A total of 80 patients with acute adnexal pathologies were identified. OT was recorded in 17 (21%) cases and ovarian cysts (OC) only in 63 (79%) cases. Patients who presented with OT were significantly younger than patients with OC only (P = .001). Correspondingly, 11 (65%) of the patients with OT had no menarche compared to 3 (5%) patients with OC only (P = .001). Vomiting (P = .001), a shorter pain duration (P = .01), and an elevated C-reactive protein (CRP) (P = .01) were observed significantly more often in patients with OT. The sensitivity of a positive OT score was 0.81 and increased to 1.00 if restricted to girls between 2 to 12 years of age.The presence of vomiting, short duration of abdominal pain, and elevated CRP level have a predictive value for the diagnosis of OT. In these patients, an exploratory laparoscopy should be conducted without delay. The presented OT score appears to be a helpful tool in diagnosing OT in children.

Case 246: MR Imaging of a Complex Cystic Mass in a Newborn Girl

History A 6-day-old female neonate presented to the outpatient pediatric surgery clinic for evaluation of a possible prenatal abdominal mass. The neonate was delivered at term via cesarean section due to macrosomia, with a reported birth weight of 11 lb 8.7 oz (5.23 kg). The patient's postnatal course was remarkable for resolving neonatal hyperbilirubinemia. A physical examination was remarkable for a palpable mass in the abdomen. Maternal risk factors included class II obesity, type 2 diabetes, and metabolic syndrome. Prenatal images obtained at an outside institution were not available at this time. Ultrasonography (US) of the abdomen and pelvis was performed 6 days after birth. Follow-up US at 29 days of life revealed no substantial change in the appearance of the findings. This patient remained asymptomatic, and gadolinium-enhanced (Magnevist; Bayer Pharma, Berlin, Germany) magnetic resonance (MR) imaging of the abdomen and pelvis was performed at 84 days of life. The mass was excised surgically at 89 days of life, and the patient had an uncomplicated postoperative course.

Evaluation and Treatment Results of Ovarian Cysts in Childhood and Adolescence: A Multicenter, Retrospective Study of 100 Patients

STUDY OBJECTIVE

To investigate the characteristics of children with ovarian cysts and evaluate treatment strategies.

DESIGN

Retrospective study.

SETTING

Eight pediatric endocrinology clinics, Turkey.

PARTICIPANTS

A total of 100 children and adolescents with ovarian cysts.

INTERVENTIONS

Patient data collected via retrospective chart review. Patients were stratified according to age into 4 groups (newborns, 1-12 months, 1-8 years, and 8-18 years).

MAIN OUTCOME MEASURES

Special emphasis was given to torsion and tumor cases, concomitant diseases, treatment modalities, and problems during follow-up.

RESULTS

Most newborns and infants were asymptomatic with the cysts being discovered incidentally; in girls ages 1-8, symptoms were common, including breast budding (47.1%, 16 of 34) and vaginal bleeding (29.4%, 10 of 34). Girls older than 8 years mostly presented with abdominal pain (31.6%, 12 of 38) and menstrual irregularity (21.1%, 8 of 38). Most of our patients were diagnosed with a simple ovarian cyst, but 9 patients were found to have ovarian tumors. Ovarian torsion was detected in 7 patients; 5 with large and 2 with small cysts (<20 mm). Two patients had central precocious puberty (CPP) at presentation and 5 patients developed CPP during follow-up. The surgical intervention rate was high (38%, 38 of 100), but was associated with earlier treatment year, and this association remained significant after adjusting for confounders (P = .035).

CONCLUSION

Most girls have simple cysts, which have a favorable prognosis without intervention; however, there might be coexisting pathologies or complications such as tumors, torsion, and CPP; hence these patients should be evaluated accordingly and treated with a multidisciplinary approach.

Rate of Oophorectomy for Benign Indications in a Children's Hospital: Influence of a Gynecologist

STUDY OBJECTIVE

To compare the rates of oophorectomy performed by pediatric surgeons for benign indications before and after the addition of a gynecologist to the surgical staff of a children's hospital. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We used a retrospective chart review of patients ages 5-21 years who underwent surgical management by pediatric surgeons for benign adnexal indications at a tertiary care children's hospital. Patient characteristics and clinical outcomes were recorded. Rates of oophorectomy for patients managed before the addition of a gynecologist (1998-2004) were compared with those managed after a gynecologist joined the surgical staff (2005-2013). Logistic regression analysis was conducted to compare the likelihood of oophorectomy before and after the addition of a gynecologist to the surgical staff.

RESULTS

One hundred sixty-five cases were included in the final analysis. Pediatric surgeons were 8 times more likely to perform an oophorectomy for benign indications before the addition of a gynecologist to the surgical staff (odds ratio, 8.3; 95% confidence interval, 3.76-18.16). Oophorectomy was performed in 45% (25/56) of cases from 1998 to 2004 compared with 11% (12/109) of cases from 2005 to 2013. Younger age (P = .009), ischemic-appearing adnexa (P < .0001), presence of torsion (P = .017), and mature teratoma (P = .041) were associated with higher likelihood of oophorectomy.

CONCLUSION

There was a higher rate of ovarian preservation for benign indications performed by pediatric surgeons after the addition of a gynecologist to the surgical staff. Younger patients, those with a mature teratoma, and ovarian torsion continue to be at higher risk for oophorectomy.

Laparoscopic Outcomes of Adnexal Surgery in Older Children and Adolescents

STUDY OBJECTIVE

To evaluate the outcomes of laparoscopic surgery for the treatment of adnexal pathology in older children and adolescents.

DESIGN

A retrospective cohort review.

SETTING

A tertiary academic center in Istanbul, Turkey.

PARTICIPANTS

Pediatric and adolescent patients aged between 9 and 19 years (n = 69) who underwent laparoscopic surgery for adnexal pathology from January 2005 through September 2015. The patients who were pregnant or with non-gynecologic pathology detected during surgery were excluded from the study.

INTERVENTIONS

Patients were divided into 2 groups according to their age. Group 1 consisted of 31 patients aged between 9 and 16 years and group 2 included 38 patients aged between 17 and 19 years.

MAIN OUTCOME MEASURES

The indication for surgery, procedures performed, anesthesia time, length of hospital stay, pathology findings, and complication rates were evaluated.

RESULTS

Ovarian cystectomy and adnexal detorsion with or without cystectomy were the most frequently performed. Ovary-sparing conservative surgery was possible for all patients, except those with gonadal dysgenesis and testicular feminization (n = 6), who underwent laparoscopic gonadectomy. The most common pathologic finding was mature cystic teratoma (30.2%), followed by benign paratubal cyst, and simple cysts of the ovary. Anesthesia time was shorter in group 2 (P = .018). The procedures performed, length of hospital stay, complication rate, and pathology findings were not significantly different between the 2 groups.

CONCLUSIONS

Laparoscopic surgery can be successfully performed as an efficient, safe, and well tolerated procedure for treating a wide variety of adnexal pathology among children and young adolescents without any significant variation between different age groups.

Management of Complex Ovarian Cysts in Newborns - Our Experience

Aims: To analyse the clinical presentation, clinicopathological correlation and management of complex ovarian cysts in newborn and infants.

Materials and Methods: Over a period of 6 years (2009-2015), 25 newborns who were diagnosed to have ovarian cyst on antenatal ultrasound, were followed up. We collected data in the form of clinical features, radiological findings, pathology and mode of treatment.

Results: Of the 25 fetuses who were diagnosed to have ovarian cysts, fourteen (56%) underwent spontaneous regression by 6-8 months. Eight were operated in newborn period while 3 were operated in early infancy. Seven had ovarian cyst on right side, 4 had on left side. Eight babies underwent laparoscopy while 3 underwent laparotomy. Histopathology showed varied features of hemorrhagic cyst with necrosis and calcification, serous cystadenoma with hemorrhage, benign serous cyst with hemorrhage and simple serous cyst. Post-operative recovery was uneventful in all.

Conclusion: All the ovarian cysts detected antenatally in female fetuses need close follow-up after birth. Since spontaneous regression is known, only complex or larger cysts need surgical intervention, preferably by laparoscopy. Majority of the complex cysts show atrophic ovarian tissue hence end up in oophorectomy but simple cysts can be removed preserving normal ovarian tissue whenever possible.

Gynecologic Surgery in the Pediatric and Adolescent Populations: Review of Perioperative and Operative Considerations

Gynecologists are often consulted on pediatric and adolescent patients who may require a surgical treatment for a gynecologic diagnosis. This patient population can present an interesting challenge for a nonpediatrician. It is helpful to review the differences in anatomy, alterations in drug dosing, surgical limitations, and counseling and consent requirements in this patient population before proceeding with a surgical treatment. This is a review of preoperative, intraoperative, and postoperative considerations for gynecologic surgery in the pediatric and adolescent patient population.

Adnexal masses in children, adolescents and women of reproductive age in the Netherlands: A nationwide population-based cohort study

OBJECTIVE

To provide an accurate incidence of adnexal masses in children and young women which can significantly improve the performance of current risk prediction models.

METHODS

We used the PALGA database, a nationwide network and registry of histopathology and cytopathology, as the primary source of our study. Reports on ovarian histology of girls, years 1991-2014, and women aged 21-39, years 2011-2013, were included. Reports were labeled using the WHO-classification and classified as benign, borderline malignant, or malignant. Surgical procedure was scored separately.

RESULTS

Included were 11,595 patients. The incidence of adnexal masses increased exponentially with age, from 0.43 per 100,000womenyears at age 1 to 152 per 100,000womenyears at age 35. A (borderline) malignancy was found in 898 (7.7%) patients, ratios between benign and malignant masses varied with age and were lowest in premenarchal children. Histology varied widely with surface epithelial tumors (35.1%), germ cell tumors (29.8%), and other cysts, tumors and tumorlike lesions (32.8%) being evenly distributed while sex cord stromal tumors were rare and only represented 2.3%. The proportion of malignancies was 6.3% in germ cell tumors while the type of malignant germ cell tumor was dependent on age. Oophorectomy was more often performed in the premenarchal age group and in women approaching the end of their reproductive age.

CONCLUSION

Our results show that adnexal masses in different age groups do not only differ in histological subgroups but also in malignancy rate which is of high value in presurgical risk evaluation.

Diagnosis of neonatal ovarian torsion: Emphasis on prenatal and postnatal sonographic findings

PURPOSE

Our aim was to retrospectively review the imaging findings of patients with neonatal ovarian torsion, emphasizing prenatal and postnatal sonographic findings.

METHODS

Eleven patients who had had neonatal ovarian torsion diagnosed surgically (n = 9) or clinicoradiologically (n = 2) were enrolled. Prenatal and postnatal sonographic features, including sequential postnatal change, were reviewed. Clinical and pathologic features were also investigated.

RESULTS

All patients except one had a fetal ovarian cyst (mean, 5.3 cm) detected on third-trimester sonography, either simple (n = 6) or complex (n = 4). In all 11 patients, initial postnatal sonography had revealed a complex cyst (mean, 4.7 cm) with intracystic clot or debris, the double-wall sign, a fluid-fluid level, and multiple septation. None of the patients had had symptoms or signs related to the ovarian torsion. Follow-up sonography in seven patients had revealed increased echogenicity of the cyst wall with frequent calcification and a decrease in size of the cyst. In two patients, the interval of the change in cyst position was noted, and autoamputation of the torsed ovary had been surgically confirmed. Serous cystadenoma had been identified in one patient.

CONCLUSIONS

Neonatal ovarian torsion most commonly manifests as an asymptomatic complex cyst on sonography due to torsion of a fetal ovarian cyst. Serial monitoring of a fetal ovarian cyst for its resolution or changes in its appearance is mandatory for making an early diagnosis of torsion. © 2016 Wiley Periodicals, Inc.

Imaging Findings of Fetal-Neonatal Ovarian Cysts Complicated With Ovarian Torsion and Autoamputation

OBJECTIVE

Large nonresolving neonatal ovarian cysts may be a risk factor for complications such as torsion, mass effect, rupture, intracystic hemorrhage, and autoamputation. Torsed cysts and autoamputated cysts can cause a diagnostic dilemma. The objective of our study was to correlate the imaging findings of intrauterine ovarian torsion and autoamputated ovaries with their pathologic findings.

MATERIALS AND METHODS

We retrospectively analyzed the pre- and postnatal medical records, sonographic findings, operation notes, and pathologic reports of 15 patients with ovarian torsion. All patients had complex cysts noted on postnatal sonographic examination. A complex heterogeneous ovarian cyst was defined by the presence of a fluid-debris level indicating hemorrhage within the cyst, a retracting clot, septations with or without internal echoes, calcification, and a solid component.

RESULTS

On ultrasound examination, four cysts had solid components, and 11 were heterogeneous and had a fluid-debris level. Calcifications were seen in two patients. The mean patient age at the time of surgery was 3.9 months. Exploratory laparotomy was performed on all patients. Torsed ovaries were identified in five patients. Ten patients had ovaries that were floating free in the peritoneal cavity at the time of surgery. Histopathologic evaluation revealed that 11 of the cysts consisted of extensive hemorrhagic, necrotic autolytic tissue with dystrophic calcification. None of the cysts contained any ovarian tissue.

CONCLUSION

A complex heterogeneous ovarian cyst with a fluid-debris level indicating hemorrhage is a significant sonographic hallmark for the diagnosis of ovarian torsion. A calcified abdominal mass, with or without wandering, can be an autoamputated ovary.

Laparoscopic ovarian surgery in children and adolescents

Background and Objectives:

Although laparoscopy is widely used in gynecologic surgery in adults, few studies have been undertaken to examine its use in young and adolescent patients. This study was conducted to investigate the safety and feasibility of laparoscopic surgery for the treatment of benign ovarian disease in children and adolescents.

Methods:

A retrospective chart review was conducted on 106 patients (age, <20 years) who underwent laparoscopic surgery at Kangnam Sacred Heart Hospital from 2006 through 2012.

Results:

The mean patient age was 17.1 years, and the youngest one was 8. Pathologic analyses revealed that 32 (30.2%) patients had dermoid cyst, 30 (28.3%) had simple cyst, and 15 (14.2%) had endometrioma. Conservative procedures, such as cystectomy (48.1%), aspiration (5.7%), fulguration (4.7%), and detorsion (3.8%), were performed in 65.1% of all cases. A subanalysis revealed that the surgical outcomes of children (age, ≤15 years), including operative time, estimated blood loss, postoperative hemoglobin decrease, and postoperative length of hospital stay, were comparable to those of adolescents (age, 16–19 years), despite significant differences in mean height between the 2 groups (156.1 ± 10.71 cm in children vs. 162.1 ± 5.14 cm in adolescents; P < .0001). (The age break between the study groups was set at 15 years, because most girls reach their adult height between the ages of 15 and 16 years.) No intra- or perioperative complications were noted. In a comparison study of surgical outcomes in 433 women (age, 20–50 years) and the 106 young and adolescent girls in our sample (age, <20 years), those in our patients were not inferior.

Conclusion:

In children and adolescents, laparoscopic surgery can be successfully performed with conventional instruments designed for use in adults.

Postnatal sonographic spectrum of prenatally detected abdominal and pelvic cysts

OBJECTIVE

The purpose of this article is to illustrate the sonographic findings of a spectrum of neonatal abdominal and pelvic cystic lesions.

CONCLUSION

Neonatal abdominal and pelvic cystic lesions can arise from many organs, and they have a broad differential diagnosis. Distinctive sonographic findings may be present and can help establish the correct cause and guide proper management.

Ovarian tumors in children and adolescents: a series of 41 cases

OBJECTIVE

Pictorial review with a detailed semiological analysis of ovarian tumors in children and adolescents to provide a relevant diagnostic approach.

PATIENTS AND METHODS

Retrospective study (2001-2011) of 41 patients under the age of 15 who underwent surgery for an ovarian mass with a definite pathological diagnosis.

RESULTS

Sixty-two percent of the lesions were benign, 33% were malignant and 5% were borderline. Germ cell tumors were most frequent (77.5%), followed by sex cord stromal tumors (12.5%) and epithelial tumors (7.5%). Malignant tumors were more frequent in children between 0 and 2 years old. On imaging, calcifications and fat were specific for germ cell tumors; the presence of a mural nodule was predictive of a mature teratoma (P<0.001). Predictive factors for malignancy were clinical, including abdominal distension (P<0.01) or a palpable mass (P=0.05), biological, including increased hCG and/or AFP levels (P<0.001) and radiological, including tumors larger than 12 cm (P<0.05), tumoral hypervascularity (P<0.01) and voluminous ascites (P<0.01).

CONCLUSION

This semiological analysis confirms the role of imaging in diagnosing the etiology of ovarian lesions in children and adolescents and emphasizes the importance identifying tumoral hypervascularity, which, in addition to classic criteria, is highly predictive of malignancy.

Fetal ovarian cyst: 2- and 3-dimensional ultrasound as a new diagnostic method to rule out ovarian torsion

Owing to the improvement in obstetric ultrasound imaging, prenatal diagnosis of ovarian masses has increased considerably. Fetal ovarian cysts can be suspected when an ultrasound scan shows intra-abdominal structures in female fetuses in the presence of normal bowel and urinary structures. The most common complication is the adnexal torsion, causing partial or complete strangulation of blood supply via ovarian vessels, leading ovarian ischemia, or necrosis. Current information regarding the treatment of fetal ovarian cysts is based on personal experiences and some case series. The management is controversial, characterized by dissimilar approaches, such as “wait and see”, prenatal or postnatal aspiration, or neonatal surgery. In more than half of the cases, spontaneous regression occurs in the prenatal or postnatal period, probably due to the small size and simple aspect. Large cysts may cause both local effects (adnexal torsion, ovarian autoamputation), and distant effects (intestinal and urinary obstruction, adhesion with adjacent organs, abdominal and thoracic mass effect, pulmonary hypoplasia, hemoperitoneum, ascites, polyhyramniosis). In the absence of accurate guidelines for management, we must start with the development of more accurate methods for diagnosing associated complications such as torsion. This case report describes the role of three-dimensional (3-D) ultrasonography as potential diagnostic method for ruling out adnexal torsion when an ovarian cyst is present.

Management of neonatal ovarian cysts and its effect on ovarian preservation

BACKGROUND/PURPOSE

Management of asymptomatic neonatal ovarian cysts varies. Some surgeons advocate initial observation, while others recommend immediate operation depending on cyst size and complexity. This study aims to compare outcomes of initial observation versus primary surgery, focusing on incidence of postnatal torsion and ovarian preservation.

METHODS

A retrospective study (1997-2012) of neonates with an ovarian mass was performed. Data on cyst size, ultrasound characteristics, clinical course, complications, and pathology were extracted.

RESULTS

Thirty-seven neonates with asymptomatic ovarian cysts were identified (N=25 observed, N=12 primary surgery). Overall, 12/25 (48%) observed had successful cyst regression, including 3/8 (38%) cysts ≥50mm and 6/15 (40%) complex. 13/25 patients (52%) underwent surgery for failure of cyst regression (11/13) or concern for interval torsion (2/13). Postnatal torsion occurred in 1/25 observation patients (4%), or 1/8 (13%) with cysts≥50mm. Overall rate of ovarian preservation between groups was not statistically different [6/8 (75%) observed versus 8/9 (89%) primary surgery; P=0.577]. Pathology found viable ovarian tissue in all oophorectomy specimens (N=3).

CONCLUSIONS

Postnatal torsion is rare. A period of observation spares half of neonates from an operation, without decreasing ovarian salvage. Initial management should consist of observation, regardless of size or complex characteristics. If operative intervention is necessary, ovary preserving techniques should be utilized.

Non-surgical management of the auto-amputated adnexa in the neonate: a report on two cases

BACKGROUND

Prenatal ovarian torsion is a rare but significant gynecologic abnormality. Current literature has yet to establish standard management in the case of auto-amputated adnexa secondary to ovarian torsion in the neonate.

CASES

We report 2 cases of abdominal masses that were diagnosed in the antenatal period and were clinically consistent with auto-amputated adnexa followed with serial ultrasonography until resolution.

SUMMARY AND CONCLUSION

To our knowledge this is the first report in the literature to document resolution of 2 pelvic masses due to auto-amputated adnexa with expectant management. This suggests expectant management is an appropriate alternative to surgical management in carefully selected cases.

Precocious pseudopuberty due to an autonomous ovarian follicular cyst: case report with a review of literatures

BACKGROUND

Small follicular cysts are commonly found in the ovaries of prepubertal girls, and in most cases, they are of no clinical importance. These cysts are usually self-limiting and resolve spontaneously. However, occasionally, these cysts may enlarge and continue to produce estrogen, resulting in signs of sexual precocity. Here, we report a case of precocious pseudopuberty associated with an autonomous ovarian follicular cyst.

CASE PRESENTATION

A 5.9-year-old girl initially presented to a local clinic with vaginal bleeding and a large unilateral ovarian cyst. At 6 months after the initial acute episode, the patient visited our hospital as the ovarian cyst had persisted and increased in size. Endocrinological examination showed elevated estrogen levels and suppressed gonadotropin levels on GnRH stimulation test. Also, no skin pigmentation or bone anomaly was noted. Based on these observations, laparoscopic cystectomy was performed, and histologic analysis confirmed the diagnosis of a follicular cyst. After the laparoscopic cystectomy, the patient's hormone levels returned to normal and no ovarian cyst was detected by ultrasound.

CONCLUSIONS

As autonomous ovarian cysts are usually self-limiting disorder, no treatment is necessary. Therefore, surgical management should be deferred as long as possible to avoid the risk of repeat surgery, as pseudoprecocious puberty due to autonomous ovarian cysts can resolve spontaneoulsy and frequently recurs. Precocious pseudopuberty with an ovarian cyst may be due to granulosa cell tumor or may be one symptom of the McCune-Albright Syndrome (MAS). A careful longer-term follow up of patients with autonomous ovarian cysts and/or molecular studies may be necessary in such cases.

Single-incision pediatric endosurgery for ovarian pathology

BACKGROUND AND OBJECTIVES

Despite being pioneered by gynecologists, single-incision endosurgery has not been widely reported for the treatment of ovarian and adnexal pathology in neonates, children, and adolescents. We describe our initial experience using single-incision pediatric endosurgery (SIPES) for these indications and discuss advantages and drawbacks.

SUBJECTS AND METHODS

All children who underwent SIPES with a preoperative diagnosis of ovarian or adnexal pathology were included in the study. Data on age, operative time, complications, length of hospital stay, and outcomes were collected.

RESULTS

From January 2010 until January 2012, 19 girls (mean age, 11.4 years; range, 6 days-17 years; weight range, 4.0-90 kg) underwent SIPES procedures for ovarian or adnexal diagnoses, including hemorrhagic/follicular/paratubal cysts (n=8), torsion (n=7), tumor (n=3), and parauterine cyst (n=1). The operations included cyst unroofing (n=4), detorsion and oophoropexy (n=7), (salpingo)oophorectomy (n=5), marsupialization of cyst (n=2), and cyst aspiration (n=1). Median operative time was 42 ± 29 minutes; there were no conversions to conventional laparoscopy or open surgery. Fifteen patients (79%) were discharged within 24 hours after the procedure. There were no peri- or postoperative complications. Histopathology showed hemorrhagic/follicular/paratubal cyst (n=7), necrotic/calcified ovarian tissue after torsion (n=6), cystadenofibroma (n=1), granulosa cell tumor (n=1), and mature teratoma (Grade 0) (n=1).

CONCLUSIONS

SIPES is an excellent alternative to conventional laparoscopy for the treatment of adnexal pathology. Using a single umbilical incision that can be enlarged instead of three smaller trocar sites facilitates the resection and extraction of ovarian masses without compromising cosmesis.
