Abstract
INTRODUCTION Laparoscopic ovarian-sparing surgery (OSS) is safe and effective management approach for benign ovarian lesions in pediatric patients. This study evaluates the outcomes of females younger than 18 years who underwent the OSS procedure between December 2013 and November 2022 at a single institution. MATERIAL AND METHODS We conducted a retrospective analysis of records from 82 females who underwent OSS for ovarian lesions. OSS was performed based on diagnostic imaging that suggested the benign nature of the lesion. RESULTS Of the 82 patients studied, 78 had unilateral lesions and 4 had bilateral synchronous lesions. The mean age was 14 years. The majority (62 cases) of the surgeries were laparoscopic, with 20 requiring conversion to open surgery due to factors such as indistinguishable edges and large size of the lesion. We identified 8 cases of ovarian torsion. The surgical specimens revealed that 46 were ovarian teratomas, 2 were granulosa cell tumors, 15 were cystadenomas, and 23 were functional cysts. There were no intraoperative complications. Two recurrences were observed in patients who were initially treated for bilateral ovarian teratomas. One patient developed a pelvic abscess. Additionally, three patients had metachronous ovarian tumors during the follow-up period. In patients followed with ultrasound imaging, the viable ovary was visualized in 83.6% of the cases (61 out of 73). CONCLUSION Our findings demonstrate the effectiveness of laparoscopic OSS in preserving ovarian function and providing clinical benefits in patients with benign ovarian lesions. We recommend regular follow-up with ultrasound to exclude metachronous lesions or recurrence. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION An increased number of children and adolescents with ovarian tumors have been managed with ovarian-sparing surgery in the last few years. However, comprehensive data on fertility outcomes and local relapse are scarce. In this study, we systematically describe the contemporary outcomes of ovarian-sparing surgery, as reported in the literature. MATERIALS AND METHODS Using PRISMA guidelines, we analyzed studies reporting ovarian-sparing techniques for ovarian tumors in children and adolescents. from 1980 to 2022. Reports with fewer than three patients, narrative reviews, and opinion articles were excluded. Statistical analysis was performed for dichotomous and continuous variables. RESULTS Of 283 articles screened, 16 papers (3057 patients) met inclusion criteria (15 retrospective/1 prospective) and were analyzed. The vast majority of studies had no long-term fertility follow-up data and direct comparison between ovarian-sparing surgery vs oophorectomy was reported in only a few studies. Ovarian sparing surgery was not associated with worse oncologic outcomes in terms of (i) tumour spillage or (ii) recurrence rates, and of key importance allowed a higher ovarian reserve at long term follow-up. CONCLUSIONS Ovarian-sparing surgery is a safe and feasible technique for benign tumors. Long-term outcome studies are needed to show efficacy and fertility preservation.

Use and Accuracy of Intraoperative Frozen Section Analysis for Ovarian Masses in Children and Adolescents. J Pediatr Adolesc Gynecol 2023; 36:155-159. [PMID: 36209999 DOI: 10.1016/j.jpag.2022.10.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 09/12/2022] [Accepted: 10/02/2022] [Indexed: 11/12/2022]
Abstract
STUDY OBJECTIVE Describe the current practice patterns and diagnostic accuracy of frozen section (FS) pathology for children and adolescents with ovarian masses DESIGN: Prospective cohort study from 2018 to 2021 SETTING: Eleven children's hospitals PARTICIPANTS: Females age 6-21 years undergoing surgical management of an ovarian mass INTERVENTIONS: Obtaining intraoperative FS pathology MAIN OUTCOME MEASURE: Diagnostic accuracy of FS pathology RESULTS: Of 691 patients who underwent surgical management of an ovarian mass, FS was performed in 27 (3.9%), of which 9 (33.3%) had a final malignant pathology. Among FS patients, 12 of 27 (44.4%) underwent ovary-sparing surgery, and 15 of 27 (55.5%) underwent oophorectomy with or without other procedures. FS results were disparate from final pathology in 7 of 27 (25.9%) cases. FS had a sensitivity of 44.4% and specificity of 94.4% for identifying malignancy, with a c-statistic of 0.69. Malignant diagnoses missed on FS included serous borderline tumor (n = 1), mucinous borderline tumor (n = 2), mucinous carcinoma (n = 1), and immature teratoma (n = 1). FS did not guide intervention in 10 of 27 (37.0%) patients: 9 with benign FS underwent oophorectomy, and 1 with malignant FS did not undergo oophorectomy. Of the 9 patients who underwent oophorectomy with benign FS, 5 (55.6%) had benign and 4 (44.4%) had malignant final pathology. CONCLUSIONS FSs are infrequently utilized for pediatric and adolescent ovarian masses and could be inaccurate for predicting malignancy and guiding operative decision-making. We recommend continued assessment and refinement of guidance before any standardization of use of FS to assist with intraoperative decision-making for surgical resection and staging in children and adolescents with ovarian masses.

Abstract
STUDY OBJECTIVE To examine the recurrence rates of pediatric benign ovarian neoplasms METHODS: A retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at 8 pediatric hospitals from January 2010 through December 2016 was conducted. Data include primary operation details, follow-up imaging, and reoperation details. RESULTS Four hundred and twenty-six females were included in our cohort, with a median age of 15 years at the time of the primary operation. Of the patients, 69% had a mature teratoma, 18% had a serous cystadenoma, and 8% had a mucinous cystadenoma. Two-thirds of patients underwent ovarian-sparing surgery. There were 11 pathologically confirmed recurrences (2.6%) at a median follow-up of 12.8 months. The pathologically confirmed recurrence was 10.5 per 100 person-months at 12 months (SE = 5.7) for mucinous cystadenomas and 0.4 months (SE = 0.4) for mature teratomas (P = .001). For half of the patients, the pathologically confirmed recurrences occurred by 12.8 months, and for 75%, they occurred by 23.3 months. There were no differences in reoperation or recurrence on the basis of initial procedure (ovary-sparing surgery vs oophorectomy). CONCLUSION We measured the pathologically confirmed recurrence rate for pediatric benign ovarian neoplasms in a large cohort. Oophorectomy was not protective against recurrence. Mucinous cystadenomas were at a greater risk of pathologically confirmed recurrence.

Abstract
Objective: The aim of this study is to analyze the characteristics of pediatric ovarian tumors (OTs) and evaluate treatment strategies for ovary-sparing tumorectomy (OST). Materials and Methods: Medical records of children from October 2011 to December 2021 were reviewed. Data regarding clinical characteristics, pathological type, and management of OST were analyzed. Results: In total, 61 patients with OTs were screened. The median age was 14.8 ± 3.0 years. The median length and volume of borderline and malignant OTs were larger than those of benign OTs (P < .001 and P = .05, respectively). There was a significant difference in the median OT volume between torsion and nontorsion OTs (P = .04). The overall OST rate was 91.8% (67/73). A total of 53.4% (39/73) lesions were treated with laparoscopic OST. The OT volume was smaller in patients who underwent laparoscopy than in those who underwent laparotomy (P = .04). The probability of intraoperative tumor rupture or spillage was higher during laparoscopy than during laparotomy (P = .02). No significant differences were observed in OT recurrence. Seven patients had borderline and malignant tumors, 3 of whom had stage IA tumors and underwent OST. None of the patients experienced relapse. Conclusions: OT size is a useful reference factor for differential diagnosis and choosing laparoscopic surgery. Intraoperative tumor rupture and spillage of benign tumors during laparoscopy and laparotomy did not seem to be associated with recurrence, and laparoscopic OST was considered safe. Further prospective studies are required to confirm these conclusions.

Failure of Operative Therapy after Ovarian-Sparing Surgery for Pediatric Benign Ovarian Neoplasms: A Retrospective Review. J Pediatr Adolesc Gynecol 2022; 35:702-706. [PMID: 36031113 DOI: 10.1016/j.jpag.2022.08.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 08/10/2022] [Accepted: 08/22/2022] [Indexed: 11/21/2022]
Abstract
STUDY OBJECTIVE To evaluate failure of initial operative therapy (incomplete tumor removal) of ovarian-sparing surgery for pediatric benign ovarian neoplasms. METHODS A retrospective review of patients up to 21 years of age who underwent ovarian-sparing surgery for a benign ovarian neoplasm from 2010 to 2016 at 8 pediatric hospitals was conducted. Failure of initial operative therapy is defined as a radiologically suspected or pathologically confirmed ipsilateral lesion with the same pathology as the primary neoplasm within 12 weeks of the initial operation. RESULTS Forty patients received imaging within 12 weeks of their primary operation. Sixteen (40%) patients had a radiologically identified ovarian abnormality ipsilateral to the primary lesion, and 5 patients were suspected to have the same lesion as their primary neoplasm. Three of the 5 patients (7.5%) underwent reoperation with pathologic confirmation of the same lesion, resulting in a pathologically confirmed failure of therapy rate of 7.5%. The other 2 patients had serial imaging that subsequently demonstrated no recurrence with lesion resolution. Age, race/ethnicity, laparoscopy vs laparotomy, presence of torsion, pathology, size of lesion, and surgeon specialty were not associated with failure of therapy. CONCLUSION In most patients who received imaging within 12 weeks of the primary operation for resection of a benign ovarian neoplasm, ovarian-sparing surgery was successful in complete tumor removal, with a low failure of therapy rate. Selected patients with suspected failure of therapy on initial imaging could be serially monitored to determine the need for repeat surgical intervention.

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.

Abstract
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.

Abstract
STUDY OBJECTIVE To assess the preoperative imaging impression and surgeon diagnostic accuracy for pediatric ovarian mature cystic teratomas (MCTs) DESIGN: Retrospective review SETTING: Eleven pediatric hospitals PARTICIPANTS: Patients ages 2 to 21 who underwent surgical management of an ovarian neoplasm or adnexal torsion with an associated ovarian lesion INTERVENTION: None MAIN OUTCOME MEASURES: Preoperative imaging impression, surgeon diagnosis, tumor markers, and pathology RESULTS: Our cohort included 946 females. Final pathology identified 422 (45%) MCTs, 405 (43%) other benign pathologies, and 119 (12%) malignancies. Preoperative imaging impression for MCTs had a 70% sensitivity, 92% specificity, 88% positive predictive value (PPV), and 79% negative predictive value (NPV). For the preoperative surgeon diagnosis, sensitivity was 59%, specificity 96%, PPV 92%, and NPV 74%. Some measures of diagnostic accuracy were affected by the presence of torsion, size of the lesion on imaging, imaging modality, and surgeon specialty. Of the 352 masses preoperatively thought to be MCTs, 14 were malignancies (4%). Eleven patients with inaccurately diagnosed malignancies had tumor markers evaluated and 82% had at least 1 elevated tumor marker, compared with 49% of those with MCTs. CONCLUSIONS Diagnostic accuracy for the preoperative imaging impression and surgeon diagnosis is lower than expected for pediatric ovarian MCTs. For all ovarian neoplasms, preoperative risk assessment including a panel of tumor markers and a multidisciplinary review is recommended. This process could minimize the risk of misdiagnosis and improve operative planning to maximize the use of ovarian-sparing surgery for benign lesions and allow for appropriate resection and staging for lesions suspected to be malignant.

Abstract
BACKGROUND With increased surgeon comfort using laparoscopy, we hypothesized resection of pediatric ovarian dermoids using laparoscopy would yield a shorter length of stay and no increase in morbidity or recurrence compared to laparotomy. METHODS A retrospective review was performed amongst eleven pediatric hospitals. Patients aged 2 to 21 who underwent resection of an ovarian dermoid from 2010 to 2020 were included. Patient characteristics, operative details, and outcomes by approach were evaluated using Chi-squared and Wilcoxon-Mann tests. RESULTS 466 patients were included, with a median age of 14.4 and median follow-up of 4.0 months. 279 patients underwent laparoscopy (60%), 139 laparotomy (30%), and 48 laparoscopy converted to laparotomy (10%). There were no differences in rates of tumor spillage by approach (p = 0.15). 65% underwent ovarian-sparing surgery and 35% underwent oophorectomy. Length of stay was significantly shorter amongst patients who underwent laparoscopy (1 day versus 2 days for laparotomy and converted, p<0.0001). There were no differences in rates of suspected recurrence or reoperation (p = 0.19 and p = 0.57, respectively). CONCLUSION Patients who underwent laparoscopy experienced no differences in the rates of tumor spillage, recurrence, or reoperation and had a shorter length of stay compared to laparotomy. Laparoscopy is an acceptable approach for resection of pediatric ovarian dermoids.

Standardizing the surgical management of benign ovarian tumors in children and adolescents: A best practice Delphi consensus statement. Pediatr Blood Cancer 2022; 69:e29589. [PMID: 35118808 DOI: 10.1002/pbc.29589] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 01/09/2022] [Accepted: 01/10/2022] [Indexed: 12/19/2022]
Abstract
AIM No widely agreed consensus protocols exist for the management of benign ovarian tumors (BOT) in children. This presents a substantial risk for suboptimal management. We aimed to generate multispecialty consensus guidance to standardize surgical management and provide a clear follow-up protocol for children with BOTs. METHODS Prospective two-round confidential e-Delphi consensus survey distributed among multispecialty expert panel; concluded by two semistructured videoconferences. MAIN RESULTS Consensus was generated on these core outcome sets: preoperative/intraoperative management; follow-up; adolescent gynecology referral. (1) Children with BOTs should receive the same management as other patients with potentially neoplastic lesions: Preoperative discussion at a pediatric oncology multidisciplinary meeting to risk stratify tumors, and management by health professionals with expertise in ovarian-sparing surgery and laparoscopy. (2) Ovarian-sparing surgery for BOTs should be performed wherever possible to maximize fertility preservation. (3) Ovarian masses detected during emergency laparoscopy/laparotomy should be left in situ wherever feasible and investigated appropriately (imaging/tumor markers) before resection. (4) Follow-up should be undertaken for all patients after BOT resection. Patients should be offered referral to adolescent gynecology to discuss fertility implications. CONCLUSION This best practice Delphi consensus statement emphasizes the importance of managing children with BOTs through a well-defined oncological MDT strategy, in order to optimize risk stratification and allow fertility preservation by ovarian-sparing surgery wherever possible.

Abstract
AIM Cystic ovarian masses in children may be physiological or neoplastic. It is mandatory that suspected neoplastic lesions are resected without tumour spillage. However, a large midline incision is cosmetically unappealing incision to young women. Here we describe our experience of using controlled drainage without spillage that allows a cosmetic pfannenstiel approach without compromising oncological principles. METHOD All girls treated with large ovarian cystic masses since 2008 in our centre were identified and data was collected prospectively. A small pfannenstiel incision was performed followed by peritoneal washings; tissue glue was used to stick an Opsite™ dressing to the cyst surface and fluid drained so there was no leakage back into the patient. Once aspirated the cyst was delivered and an ovarian preserving cystectomy was performed where possible. RESULTS Twenty-three girls (median age 14.5 years (8.1 to 16.5 years) were included. Pre-operative MRI scan showed a complex lesions with median volume of 1169 ml (range 252-7077 ml). At surgery 22/23 cysts were intact and removed without spillage. HISTOLOGY mature teratoma (11), serous cyst (3), mucinous cyst adenocarcinoma (2), mucinous cystadenoma (5), Sertoli-Leydig tumour, sclerosing stromal tumour. One girl with pre-operative rupture of a mucinous adenocarcinoma subsequently died. Ovarian sparing cystectomy was performed in 17/23 girls. All other patients are well without evidence of recurrence. CONCLUSION This is the largest series in children and adolescents using controlled drainage of cystic ovarian tumours. Though there were a range of diagnoses we have shown that these can be removed safely with a cosmetic pfannenstiel approach while following oncological principles.

Abstract
BACKGROUND Ovarian neoplasms in children are rare heterogeneous lesions with variable biological behaviour and outcome. We herein report a 25-year experience from a UK specialist centre managing paediatric ovarian tumours. METHODS All female patients requiring operation for ovarian tumours were identified during the study period 1990-2018. Patient demographics, clinical presentation, and management are highlighted. RESULTS Eighty-eight females with 101 ovarian tumours including cases with synchronous and metachronous neoplasms were documented. Mean age at diagnosis was 11.8 years. Tumours were equally distributed in left and right ovary(s). Bilateral disease occurred in 11 (10.8%) patients. Eighty-six (85%) neoplasms were benign and 15 (15%) malignant requiring in addition to surgery chemotherapy and/or radiation. There were no significant difference(s) observed in maximum tumour diameter in benign vs malignant lesions. Only half of malignant tumours had positive tumour markers. Fifteen patients (15%) had ovarian lesions that were metastatic at primary presentation including a rare case of disseminated peritoneal gliomatosis. Surgical management included salpingo-oopherectomy n = 21 (21%), ovary excision n = 33 (33%), 'ovary sparing' tumourectomy n = 34 (34%), and cyto-reductive extirpation in 2 cases (2%). Lymphadenectomy was performed in 9 patients (9%) together with peritoneal fluid cytology in 18 cases (18%) who had abdominal ascites. Omentectomy was required in 14 patients (14%), multiple peritoneal biopsy(s)-in 11 cases (11%) and biopsy of other suspicious involved organs notably bowel, gut mesentery and contralateral ovary in 7 (7%) further patients. Recurrent and metachronous lesions occurred in 10 (10%) cases in those with teratoma (n = 9) and adenocarcinoma(s) (n = 1). Overall patient survival was 97% with only 3 deaths-mucinous cystadenocarcinoma (n = 1), desmoplastic small round cell tumour of ovarian origin (n = 1), and a small cell carcinoma of ovary with hypercalcaemia (n = 1). CONCLUSIONS Findings from this study show an excellent survival (97%) for paediatric ovarian neoplasms. Rare malignant neoplasms though do carry a poor prognosis. In the modern era of care, all efforts should be made to preserve future hormonal health and fertility with 'ovarian sparing' operation(s) where appropriate.

Abstract
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.

Abstract
PURPOSE To investigate the clinicopathololgic characteristics and the predicting value of preoperative imaging and tumor markers in children with ovarian masses. METHODS Patients admitted in Shanghai children's hospital with ovary neoplasms between 2010.01 and 2015.12 were retrospectively analyzed. The medical records including age at operation, presentation of symptoms and signs, tumor marker, imaging, pathology, tumor diameter and surgical choice were reviewed. All data were analyzed using SPSS 17.0 RESULTS: A total of 139 patients were included, among which 116 were benign neoplasms and 23 malignant tumors. There was significance difference relation with the tumor diameter, character, torsion and tumor markers, but not the age, position, calculi, and symptoms. The risk factors include tumor diameters ≥ 10 cm, the odds ratio (OR) was 11, 95% confidence interval (CI) was 3-36, solid/complex tumor (OR 6, 95% CI 2, 14) and positive in tumor markers (OR 84, 95% CI 20, 345). Among the patients with benign neoplasms, 77 of them had laparoscopic ovarian cystectomy while 23 patients with malignant tumors had salpingo-oophorectomy and omentum resection. CONCLUSION Preoperative imaging and tumor markers could help identifying the malignant ovarian masses in children. If tumor diameter ≥ 10 cm, solid/complex in imaging and tumor markers abnormal, a radical resection is mandatory; otherwise, an ovarian-sparing surgery is recommended.
