Current Status of Fertility Preservation in Pediatric Oncology Patients.

Cancer poses significant emotional challenges for children and adolescents, despite improvements in survival rates due to new therapies. However, there is growing concern about the long-term effects, including fertility issues. This review examines recent advancements and future directions in fertility preservation within a pediatric population subjected to oncological therapies. Worldwide, there is variability in the availability of fertility preservation methods, influenced by factors like development status and governmental support. The decision to pursue preservation depends on the risk of gonadotoxicity, alongside factors such as diagnosis, treatment, clinical status, and prognosis. Currently, options for preserving fertility in prepubertal boys are limited compared to girls, who increasingly have access to ovarian tissue preservation. Adolescents and adults have more options available, but ethical considerations remain complex and diverse.

Anastomosis near to the ileocecal valve in neonates with focal intestinal perforation, is it safe.

BACKGROUND: Anastomosis near the ileocecal valve (ICV) are controversial due to the increased pressure on the suture; in this situation, the valve could be removed at a first stage or at the moment of stoma closure. However, preservation of the ICV has proved important benefits in the long term. The aim of this study is to evaluate its feasibility in neonates with focal intestinal perforation (FIP). METHODS: Retrospective study (2010-2019) of neonates with FIP who underwent intestinal resection and primary anastomosis. Patients were divided into group A (anastomosis less than 5 cm from ICV) and group B (more than 5 cm). RESULTS: Forty patients were treated. Patients ostomized or with resection of ICV were excluded. Finally, 24 patients (birth weight 1043 ± 594 g (520-3000), age 8.8 ± 7.8 days (2-39)) were included for analysis. Patent ductus arteriosus was present in 75%. There were 6 patients in group A (25%) and 18 in group B (75%). Groups were comparable in terms of gestational age, birth weight, and age at the time of surgery (p > .05). There were no cases of dehiscence nor stenosis of the anastomosis. There were no differences in reoperation rate, infectious complications, time to enteral feeding, days of parenteral nutrition, hospital stay nor survival (p > .05). CONCLUSION: Ileo-ileal anastomosis closer to the ileocecal junction, in neonates with focal intestinal perforation, is an effective and safe option which also allows the preservation of the ICV avoiding the complications derived from its absence in a group of patients with high morbidity.

Results of Ovarian Sparing Surgery in Pediatric Patients: Is There a Place for Laparoscopy?

Background: Laparoscopy is widely accepted for the surgical treatment of benign ovarian lesions in adult women, with results similar to an open approach when spillage is avoided by different means such as endobag retrieval. This approach is controversial in children. Materials and Methods: Retrospective study (2009-2018) of all pediatric ovarian tumors with histological confirmation treated in a tertiary center. Data regarding preoperative selection criteria, surgical technique, and follow-up were registered. Laparoscopy was used only in tumors without malignant features and whose size allowed retrieving them through a small incision without morcellating. Emphasis was set in ovarian sparing surgery (OSS), comparing the results of open (OP) and laparoscopic (LPC) approach. Results: During the study period, 48 suspicious lesions in 45 patients were operated. Thirty cases (32 tumors) showed benign features (10 cystadenomas, 14 mature teratomas, 6 nontumor lesions); treatment consisted in oophorectomy in 13 (OP 6, LPC 7) and OSS in 17 (OP 5, LPC 12). There was one conversion in the LPC group. Mean follow-up was 3.44 years (range 0.03-8.84), based on annual ultrasound (US) and tumor markers during at least 5 years, recommending a lifetime follow-up by a gynecologist. There was only one relapse in a laparoscopically enucleated cystadenoma, and 2 patients developed contralateral metacronous teratomas. No procedure-related complications happened. Conclusions: Our series, although small and with a limited follow-up, suggest that laparoscopy could be an option of treatment in a subset of highly selected patients, although laparotomy remains the gold standard approach if malignancy is suspected.

Management of neonates with right-sided aortic arch and esophageal atresia: International survey on IPEG AND ESPES members´ experience.

AIM: The optimum surgical approach of neonates with right-sided aortic arch (RAA) and esophageal atresia (EA)/tracheoesophageal fistula (TEF) is still an unsolved question. In order to propose an operative algorithm in the era of endoscopic surgery, we performed an international survey to know the current practice between pediatric endoscopic surgeons. Two of the most important societies in endoscopic pediatric surgery were queried: the International Pediatric Endosurgery Group (IPEG) and the European Society of Paediatric Endoscopic Surgeons (ESPES). MATERIALS AND METHODS: During December 2016, an anonymous online-based survey was sent to all IPEG and ESPES members, collecting data regarding perioperative management and surgical repair of EA/TEF with RAA. RESULTS: 144 surgeons from 23 countries completed the questionnaire. 69.2% of respondents were IPEG members, 30.8% were ESPES members. 71.5% of members who answered the survey had more than 10years of surgical experience. A preoperative echocardiography was almost uniformly performed (93.1%). 31.9% of the surveyed surgeons had never treated an EA/TEF with RAA. The remaining 98 surveyed surgeons had managed 279 cases of EA/TEF with RAA. Thoracotomy was considered the preferred approach for 54.2% of the surgeons, and 51.9% chose a right-sided approach. When RAA was an intraoperative finding, 76% would perform a contralateral thoracotomy if difficulties arose. Thoracoscopy was preferred by 45.8% of surgeons. If RAA was suspected preoperatively, 63.1% preferred to attempt a left-sided thoracoscopy and only 24.2% would change their approach to a thoracotomy. If RAA was an intraoperative finding and a safe surgical repair could not be achieved through right-sided thoracoscopy, 51.5% of them chose to perform a left sided thoracoscopy, rather than convert to thoracotomy. CONCLUSIONS: Preoperative echocardiography performed by experienced examiners helps in surgical planning. Preoperative diagnosis of RAA should not discourage thoracoscopic repair, which is increasingly becoming more popular for the correction of EA/TEF. In case of an unexpected intraoperative diagnosis of RAA or operative difficulties when approaching through the right side, thoracoscopy offers a less aggressive approach. LEVEL OF EVIDENCE: V.
