Isolated Fallopian Tube Torsion in Children With Hydrosalpinx: Is Conservative Management an Option?

BACKGROUND: Isolated fallopian tube torsion (IFTT) is very rare gynecological emergency in pediatric population. Our objective is to assess treatment options and discuss outcome of a cohort of IFTT with a focus on the association between IFTT and hydrosalpinx (HSX). METHODS: A retrospective review was conducted. Pediatric patients with IFTT operated in the same center were included. RESULTS: Seventeen girls (aged: 11-16 years) were managed for acute abdominal pain between 2008 and 2018, with intraoperative diagnosis of IFTT. All patients underwent laparoscopic exploration, with laparoscopically fallopian tube detorsion in all patients. Based on the association of IFTT with HSX after fallopian tube detorsion, patients were divided into 2 groups: group 1 (IFTT without HSX; 12 girls) and group 2 (IFTT with HSX; 5 girls). During the same surgery, complementary surgical procedures were done. In group 1: salpingectomies (4), partial salpingectomies (2) and cystectomies (6) were done. In group 2: salpingectomy (1), salpingotomy (1), and cyst ablation (1). The treatment was called conservative when the tube was preserved.Follow-up was uneventful in group 1. In group 2, for all patients with initial fallopian tube preservation, further surgical procedures were necessary (1-4 surgeries/patient), and, finally, another 3 patients required salpingectomy. CONCLUSIONS: Conservative treatment with tube preservation of IFTT without HSX appeared to be beneficial compared to those with HSX, with no recurrence of torsion or symptoms during the follow-up. However, the same conservative treatment was not sufficiently effective for IFTT with HSX and required further procedures due to recurrence of torsion. LEVEL OF EVIDENCE: IV.

Hypospadias preputial flap onlay technique - Step by step.

PURPOSE: To present one way of performing onlay preputial flap for hypospadias. PATIENTS AND METHODS: This procedure was performed following the methodology used in one hypospadias expert center to correct hypospadias in boys who are not elective for Koff procedure and in whom Koyanagi procedure is not needed. Operative details were described, and post-operative management were given as example. RESULTS: Long-term results of this technique showed a 10% complication rate (dehiscence, strictures or urethral fistulas) 2 years after surgery. CONCLUSIONS: This video is a step by step description of the onlay preputial flap technique giving the general methodology and also the details resulting from years of practice in one hypospadias expert center.

Changes in the clinical management of 5α-reductase type 2 and 17ß-hydroxysteroid dehydrogenase type 3 deficiencies in France.

Objectives: To examine the changes in diagnostic practices and clinical management of patients with 5α-reductase type 2 (SRD5A2) or 17ß-hydroxysteroid dehydrogenase type 3 (HSD17B3) deficiency since molecular diagnoses became available. Methods: Clinical, laboratory, and therapeutic data were retrieved from the medical records of 52 patients with a molecular diagnosis of SRD5A2 (n = 31) or HSD17B3 (n = 21) deficiency. Temporal trends regarding age at assessment and initial sex assignment over 1994-2020 were qualitatively analyzed. Age at molecular diagnosis was compared between two subgroups of patients according to their year of birth. Results: Fifty-eight percent (n = 30) patients were diagnosed during the perinatal period, 33% (n = 17) during infancy, and 9% (n = 5) during adolescence or adulthood. Over the studied period, the patients' age at initial assessment and diagnosis frankly decreased. The median (range) age at diagnostic confirmation was 10.5 (0-53.2) years for patients born before 2007 and 0.4 (0-9.3) years for those born in 2007 or later (P = 0.029). Genetic testing identified 27 different variants for the SRD5A2 gene (30% novel, n = 8) and 18 for the HSD17B3 gene (44% novel, n = 8). Before 2002, most patients were initially assigned as females (95%, n = 19), but this proportion dropped for those born later (44%, n = 14; P < 0.001). The influence of initial genital appearance on these decisions seemingly decreased in the most recent years. Therapeutic interventions differed according to the sex of rearing. Ten percent (n = 2) patients requested female-to-male reassignment during adulthood. Conclusion: This study showed, over the past two decades, a clear trend toward earlier diagnosis and assignment of affected newborns as males.

Tumoral and pseusotumoral processes of the vagina in the pediatric population: A 26-YEAR retrospective study.

BACKGROUND: Vaginal lesions are rare and of various types in children. Clinical presentation is generally undifferenciated. Histological examination is fundamental to ascertain the nature of the lesion. Regarding tumoral lesions, histological subtypes encountered are radically different from those seen in adults, dominated by stromal benign lesions. OBJECTIVE: The aim of this retrospective study was to describe characteristics and pathological aspects of pediatric vaginal lesions, diagnosed in a single pediatric experienced center. STUDY DESIGN: A database analysis was performed on all vaginal samples of patients under 18 years old received in a pediatric-specialized pathology laboratory of an academic hospital, over a 26-year period. RESULTS: Among 36 vaginal tissue samples reported, a total of 15 tumoral or pseudotumoral processes was recorded. Primitive malignant tumors included embryonal rhabdomyosarcoma (n = 3) and germ-cell tumors, yolk-sac type (n = 2). Benign tumoral or pseudotumoral processes included inflammatory stromal polyps (n = 8), epidermic cyst (n = 1), and benign Müllerian papilloma (n = 1). DISCUSSION: Over 15 primitive vaginal tumors, 1/3 was malignant with embryonal rhabdomyosarcoma being the most common. The remaining 2/3 specimens were benign, with stromal inflammatory lesions being the most commonly observed. Fibro-epithelial polyp is a debated entity, which covers a wide histological spectrum, with varying inflammation and stromal cellularity, raising sometimes the question of the differential diagnosis with rhabdomyosarcoma. Stromal cells morphology along with their immunohistochemical profile suggest their reactive myofibroblastic nature. Pseudotumoral inflammatory lesions display very similar histological findings with these entities. A common pathogenesis beginning with an inflammatory process, potentially accelerated by chronic traumatic factors, could be discussed. CONCLUSION: We confirmed the rarity and the diversity of vaginal lesions in children. Vaginoscopy and biopsy sample should be systematic, given the non-specific presentation of tumoral processes. Myogenin immunostain must be systematic in case of vaginal polypoid mass, in order to rule out malignancy.

Preoperative Topical Estrogen Treatment vs Placebo in 244 Children With Midshaft and Posterior Hypospadias.

PURPOSE: Urethral fistula and dehiscence are common after hypospadias surgery. Preoperative androgens have been considered to reduce these complications although this consideration is not evidence-based. Dermatologists have reported the benefits of topical estrogens on skin healing. We investigated whether the preoperative use of topical promestriene could reduce healing complications in hypospadias surgery. Our primary objective was to demonstrate a reduction of healing complications with promestriene vs placebo. Impact on reoperations and other complications, clinical tolerance, bone growth, and biological systemic effects of the treatment were also considered. METHODS: We conducted a prospective, randomized, placebo-controlled, double-blind, parallel group trial between 2011 and 2015 in 4 French centers. One-stage transverse preputial island flap urethroplasty (onlay urethroplasty) was selected for severe hypospadias. Promestriene or placebo was applied on the penis for 2 months prior to surgery. The primary outcome was the presence of postoperative urethral fistula or dehiscence in the first year postsurgery. For safety reasons, hormonal and anatomical screenings were performed. RESULTS: Out of 241 patients who received surgery, 122 patients were randomized to receive placebo, and 119 patients received promestriene. The primary outcome was unavailable for 11 patients. Healing complications were assessed at 16.4% (19/116) in the placebo vs 14.9% (17/114) in the promestriene arm, and the odds ratio adjusted on center was 0.93 (95% confidence interval 0.45-1.94), P = 0.86. CONCLUSIONS AND RELEVANCE: Although we observed an overall lower risk of complications compared to previous publications, postsurgery complications were not different between promestriene and placebo, because of a lack of power of the study or the inefficacy of promestriene.

Mayer-Rokitansky-Künster-Hauser syndrome due to 2q12.1q14.1 deletion: PAX8 the causing gene?

Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) is a rare malformative disorder, characterized by congenital aplasia of the uterus and the upper two thirds of the vagina (MIM #277000). For a majority of patients, the disorder remained without identified genetic cause. However, four recurrent microdeletions, i.e. 1q21.1-16p11.2-17q12 and 22q11.21, as well as variants in genes contained in these loci, have been identified in a small number of cases. We describe an additional patient with 2q12.1q14.1 microdeletion, showing MRKH and congenital hypothyroidism due to thyroid gland hypoplasia. The patient received a dual diagnosis with microdeletion of SHOX locus in addition to the 2q12.1q14.1 microdeletion. Literature review and database analysis has enabled us to identify 5 OMIM morbid genes: CKAP2L, IL1B, IL1RN, IL36RN and PAX8. Among these, PAX8 (Paired Box Gene 8), a transcriptional factor part of the paired-box family, plays a key role in the development of the thyroid gland, kidneys and Müllerian derivatives. We discuss here the role of PAX8 and speculate on the possible involvement of PAX8 in MRKH. In this study, we report a second case of 2q12.1q14.1 microdeletion, involving PAX8 as a gene associated with Müllerian agenesis in a MRKH I and hypothyroidism. Further studies will confirm the direct participation of PAX8 in gene target sequencing in a population of MRKH with hypothyroidism.

Reversion SAMD9 Mutations Modifying Phenotypic Expression of MIRAGE Syndrome and Allowing Inheritance in a Usually de novo Disorder.

Context: MIRAGE (Myelodysplasia, Infection, Restriction of growth, Adrenal hypoplasia, Genital phenotypes, Enteropathy) syndrome is a severe multisystem disorder with high mortality. It is caused by a heterozygous gain of function mutation in the growth repressor gene SAMD9. The increasing number of reported cases displays a spectrum of phenotypes that may be explained by an adaptation mechanism, with appearance of a somatic second hit mutation with revertant effects. Objective: To determine the genetic basis of the MIRAGE syndrome rapidly corrected in a living and healthy 46,XY patient. Subjects and Methods: A 46,XY patient born with growth restriction and disorders of sex development had thrombocytopenia and necrotizing enterocolitis during the neonatal period suggestive of the syndrome. Faced with the rapid improvement of the patient's phenotype, an adaptation mechanism was sought by repeating genetic analysis at different ages; her parents also underwent genetic analysis. Results: The previously described p.(Thr778Ile) mutation was identified and surprisingly transmitted by the asymptomatic mother in this usually de novo syndrome. To explain the rapid improvement of the patient's phenotype and absence of symptoms in the mother, an adaptation mechanism was sought. For the mother, a non-sense mutation was found (p.(Arg221*)) in cis, and most likely appeared in utero. It was not transmitted to her child. The child harbored a different non-sense mutation (p.(Arg285*)) that most likely appeared near day 20. Conclusions: We show that pathogenic variants can be inherited from a healthy parent as the adaptation mechanism may arise early in life and mask symptoms. Presence of revertant mosaicism mutations could explain "incomplete penetrance" in other disease. For a better management and outcomes in patients, appearance of this natural gene therapy should be sought by repeating genetic analysis.

[Atypical genital development and tumor risk]. / Atypie du développement génital et risque tumoral : synthèse de la réunion scientifique du 25 mai 2018 organisée par le « Centre de référence des maladies rares du développement génital du fœtus à l'adulte ¼.

Atypical genital development (AGD), also called disorders of sex development are a set of miscellaneous pathologies who have in common a morphological and/or functional abnormality of the internal and/or external genital organs. The Chicago classification identifies 3 major groups based on karyotype, hormone balance and genetic studies. Some AGD predispose to the occurrence of tumors, mainly malignant germ cell tumors. The tumor risk depends on many factors: the type of AGD, the position of the gonad, the age of the patient, the phenotype, the function of the gonad and the presence of germ cells in the gonad. AGD with the highest tumor risk are those with gonadal dysgenesis, implying an incomplete differentiation of the bipotential gonad (dysplasia). Monitoring of patients with AGD and indication of prophylactic gonadectomies should be individualized according to tumor risk.

Surgery of Anomalies of Gonadal and Genital Development in the "Post-Truth Era".

This article aims to examine the current issues of debate concerning the management of atypical gonadal and genital development (AGD). Understanding this complex subject begins with defining the distinct AGD conditions, the aims and nature of surgical treatments, and the perceptions of affected individuals and their families. The evolving societal and medical contexts in this field are confronting facts and opinions, leading to a significant change in attitudes and approaches.

Concealed epispadias associated with a buried penis.

OBJECTIVE: The aim was to describe the clinical presentation and the surgical management of penile epispadias associated with a buried penis in five children. PATIENTS AND METHODS: This is a 5-year retrospective review of patients presenting with a buried penis, a congenital defect of the penile skin shaft associated with an unretractable foreskin for whom a penile epispadias was found at the time of surgery. All had undergone surgery combining a Cantwell-Ransley procedure and refashioning of the penile skin following the authors' technique. RESULTS: Three children had a glanular epispadias and two had a midshaft epispadias. Four had a satisfactory outcome, and one required a complementary urethroplasty for glanular dehiscence. CONCLUSION: Buried penis and epispadias are usually isolated congenital anomalies, although they can be associated. It is therefore recommended to warn parents about the possibility of underlying penile anomaly in children with buried penises and unretractable foreskin. Careful palpation of the dorsum of the glans through the foreskin looking for a dorsal cleft could indicate an associated epispadiac urethra. Surgical correction of both anomalies can be done at the same time. Parents of boys with buried penises should be warned that underlying penile anomaly may exist.

A novel morphological approach to gonads in disorders of sex development.

Disorders of sex development are defined as congenital conditions with discordance between the phenotype, the genotype, the karyotype, and the hormonal profile. The disorders of sex development consensus classification established in 2005 are mainly based on chromosomal and biological data. However, histological anomalies are not considered. The aims of this study were to define the specific pathological features of gonads in various groups of disorders of sex development in order to clarify the nosology of histological findings and to evaluate the tumor risk in case of a conservative approach. One hundred and seventy-five samples from 86 patients with disorders of sex development were analyzed following a strict histological reading protocol. The term 'gonadal dysgenesis' for the histological analysis was found confusing and therefore excluded. The concept of 'dysplasia' was subsequently introduced in order to describe the architectural disorganization of the gonad (various degrees of irregular seminiferous tubules, thin albuginea, fibrous interstitium). Five histological types were identified: normal gonad, hypoplastic testis, dysplastic testis, streak gonad, and ovotestis. The analysis showed an association between undifferentiated gonadal tissue, a potential precursor of gonadoblastoma, and dysplasia. Dysplasia and undifferentiated gonadal tissue were only encountered in cases of genetic or chromosomal abnormality ('dysgenesis' groups in the disorders of sex development consensus classification). 'Dysgenetic testes', related to an embryonic malformation of the gonad, have variable histological presentations, from normal to streak. Conversely, gonads associated with hormonal deficiencies always display a normal architecture. A loss of expression of AMH and α-inhibin was identified in dysplastic areas. Foci of abnormal expression of the CD117 and OCT4 immature germ cells markers in dysplasia and undifferentiated gonadal tissue were associated with an increased risk of neoplasia. This morphological analysis aims at clarifying the histological classification and gives an indication of tumor risk of gonads in disorders of sex development.

Surgery in disorders of sex development (DSD) with a gender issue: If (why), when, and how?

Ten years after the consensus meeting on disorders of sex development (DSD), genital surgery continues to raise questions and criticisms concerning its indications, its technical aspects, timing and evaluation. This standpoint details each distinct situation and its possible management in 5 main groups of DSD patients with atypical genitalia: the 46,XX DSD group (congenital adrenal hyperplasia); the heterogeneous 46,XY DSD group (gonadal dysgenesis, disorders of steroidogenesis, target tissues impairments …); gonosomic mosaicisms (45,X/46,XY patients); ovo-testicular DSD; and "non-hormonal/non chromosomal" DSD. Questions are summarized for each DSD group with the support of literature and the feed-back of several world experts. Given the complexity and heterogeneity of presentation there is no consensus regarding the indications, the timing, the procedure nor the evaluation of outcome of DSD surgery. There are, however, some issues on which most experts would agree: 1) The need for identifying centres of expertise with a multidisciplinary approach; 2) A conservative management of the gonads in complete androgen insensitivity syndrome at least until puberty although some studies expressed concerns about the heightened tumour risk in this group; 3) To avoid vaginal dilatation in children after surgical reconstruction; 4) To keep asymptomatic mullerian remnants during childhood; 5) To remove confirmed streak gonads when Y material is present; 6) It is likely that 46,XY cloacal exstrophy, aphallia and severe micropenis would do best raised as male although this is based on limited outcome data. There is general acknowledgement among experts that timing, the choice of the individual and irreversibility of surgical procedures are sources of concerns. There is, however, little evidence provided regarding the impact of non-treated DSD during childhood for the individual development, the parents, society and the risk of stigmatization. The low level of evidence should lead to design collaborative prospective studies involving all parties and using consensual protocols of evaluation.

Late prenatal dexamethasone and phenotype variations in 46,XX CAH: concerns about current protocols and benefits for surgical procedures.

OBJECTIVE: To describe the action of prenatal dexamethasone (PreDex) on the anatomy of female congenital adrenal hyperplasia (CAH) genitalia when started at later stages of gestation. MATERIALS AND METHODS: Our group follows a large cohort of French CAH patients who underwent PreDex therapy, of whom 258 were recently reported. Four 46,XX patients with a delayed PreDex treatment presented with a virilized genitalia and required surgical reconstruction. This is a retrospective report on genital phenotyping at the time of surgery of these four patients who began PreDex therapy at 8, 12, 20, and 28 weeks of gestation. RESULTS: Although this series is limited in number, the anatomical description of the length of the genital tubercle, the height of the urethra-vaginal confluence, and the degree of fusion of the genital folds seems to be dependent upon the starting date of PreDex. Most PreDex treatments prescribed up to now have covered the full duration of gestation. CONCLUSIONS: Our findings suggest that PreDex therapy could be limited to the period of the partitioning window. It is hoped that further prospective multicentric clinical studies will obtain ethical approval in order to elucidate the place and protocols of PreDex therapy in the management of CAH.

Long-term outcome of hypospadias surgery: current dilemmas.

PURPOSE OF REVIEW: To list the main questions and dilemmas raised by hypospadias management and its long-term evaluation. RECENT FINDINGS: Criteria of evaluation of hypospadias have changed in terms of anatomical description and biological screening. A better understanding of the causative and epidemiological aspects of the development anomalies of the genital tubercle has led to a more adjusted biological and surgical approach. The place of preoperative biological screening, preoperative hormonal stimulation and the choice of urethroplasty are the three main fields of discussion between hypospadiologists. Evaluation of outcome is the critical point as there are no current consensual protocols, and long-term results are often lacking as well as psychological evaluation. SUMMARY: Efforts are made to coordinate the management and evaluation of disorders of sex development (DSD) patients and more specifically hypospadias patients. National, European (EuroDSD) and international (consensus conferences) aim at finding common tracks to improve the quality of treatment and follow-up.

Does androgen stimulation prior to hypospadias surgery increase the rate of healing complications? - A preliminary report.

OBJECTIVE: Androgens have a positive effect on penile growth in children, but they may also have a repressive effect on the healing process. The aim of this prospective study was to compare the outcomes of onlay urethroplasty with and without preoperative androgen stimulation in patients with severe hypospadias. PATIENTS AND METHOD: Of 300 severe hypospadias cases treated at a single institution, 126 operated on by the same surgeon had complete follow-up data, and 30 of these received preoperative androgen treatment (human chorionic gonadotrophin and/or systemic testosterone) 1-24 months before surgery. RESULTS: Thirty-five patients presented with a complication (27.7%) of whom 26 (20.6%) had a fistula or dehiscence. Among patients on androgen stimulation there was a 30% healing complication rate (9/30) whereas for those without this was 17.7% (17/96). When androgenic treatment was given > 3 months prior to surgery the healing complication rate was 21.7% (5/23), and when < 3 months prior to surgery the rate reached 57% (4/7). Mean follow up was 41 months (10-97). CONCLUSION: Although the numbers were too small in this series to reach statistical significance, the tissular interactions of androgens in the healing process reported by dermatologists should alert the hypospadiologists and lead to a further prospective study to define the optimal protocol for stimulation of the penis in specific cases without affecting outcome.

The surgical challenges of disorders of sex development (DSD).

Disorders of Sex Development (DSD) remain a fascinating challenge for the paediatricians, endocrinologists, biologists, psychiatrists, geneticists, radiologists, surgeons and for the whole society. This article aims at highlighting the current controversies and questions met with genital reconstruction in children born with abnormal genitalia. The main current techniques of masculinization and feminization are reviewed with their progress and their problems. The tools of decision used to assign a gender in some newborns with complex DSD are discussed showing that at the dawn of the third millenium, one still does not know why a boy is a boy, and a girl is a girl.

Surgical options in disorders of sex development (dsd) with ambiguous genitalia.

Disorders of sexual development (DSD) include three main groups of patients: (1) The virilised 46,XX DSD essentially represented by congenital adrenal hyperplasia (CAH) ; (2) The undervirilised 46,XY DSD essentially represented by hypospadias; and (3) the chromosomic jigsaws essentially represented by mixed gonadal dysgenesis. It is in this last group that gender assignment remains a difficult decision involving various indicators, which can be split into four categories: (1) the inside sex (i.e., genes, hormones and target tissues); (2) the outside sex (i.e., anatomy of genitalia including size of the genital tubercle, mullerian cavity and potential adult height of the patient); (3) the functional sex (i.e., potential sexuality and fertility); and (4) and the social sex (i.e., the cultural medium in which the child is brought up). The challenge is to outline the future individual identity of the child in the postnatal period using these indicators. Current evolutions of surgical techniques of 'feminisation' and 'masculinisation' are described as well as their outcomes.

Outcome of severe hypospadias repair using three different techniques.

OBJECTIVE: To compare the outcomes of three different urethroplasty techniques (onlay, buccal mucosa, Koyanagi type I) used in the reconstruction of severe hypospadias. PATIENTS AND METHODS: Over 10 years (1997-2007), 300 severe hypospadias cases were treated with a mean follow up of 2 years (1-105 months); 203 were operated by the same surgeon of whom 184 completed follow up. Three main techniques were used according to the quality of the urethral plate: onlay urethroplasty (133), buccal graft urethroplasty (25) and Koyanagi type I (26). The mean age at surgery was 36 months (8-298); 76 required preoperative androgen stimulation (onlay 37, buccal 11, Koyanagi 26); 18 required a corporoplasty to straighten the penis (onlay 13, buccal 3, Koyanagi 2). RESULTS: Thirty-eight onlay (28.5%); 14 buccal (56%); 16 Koyanagi (61.5%) urethroplasties had a complication. The fistula rate was 15% for the onlay group; 32% for the buccal mucosa group; 19.2% for the Koyanagi cases. The dehiscence rate was, respectively, 11.3%, 20% and 42.3%. The stricture rate was, respectively, 1.5%, 20% and 34.6%. Urethrocele was found in seven Koyanagi patients. Final functional and cosmetic results were satisfactory in 126/133 (94.7%) onlay, 20/25 (80%) buccal and 14/26 Koyanagi (53.8%) urethroplasties. Primary cases had better results (89%) than redo cases (75.9%). Patients submitted to preoperative androgen therapy developed more complications (onlay: 40.5% vs 23.9%; buccal: 70% vs 43.7%). CONCLUSION: Two striking results are the low number of severe hypospadias cases requiring an additional corporoplasty, and the increased complication rate found in androgen-stimulated patients. The excellent results of the onlay procedure could be related to the use of dorsal preputial tissue, which in hypospadias is characterized by a well-balanced protein platform compared to the ventral tissues.

Scheduled preterm delivery for gastroschisis improves postoperative outcome.

There are some evidence to suggest that careful antenatal monitoring, scheduled preterm delivery and immediate abdominal wall closure may reduce gastroschisis morbidity. We hypothesised that the advantages of a scheduled preterm delivery balance possible complications related to prematurity. A retrospective study was performed including all cases of gastroschisis born between 1990 and 2004 (n = 69). Cases were categorised in two groups. Group 1 contained gastroschisis cases born between 1990 and 1997. Group 2 contained cases occurring since 1997, when a new management pathway for gastroschisis was established: weekly evaluation of the foetal gut by ultrasound (>28 weeks), corticosteroids, and delivery by scheduled caesarean section at 35 weeks (before if evidence of bowel compromise was present). The primary endpoints of this study were the initiation of oral feeding and the number of re-operation for intestinal obstruction. There was a significantly faster initiation of oral feeding (P < 0.0001), however, duration of parenteral nutrition (34 vs. 38 days) and hospital discharge (53 vs. 58.5 days) was not reduced. There was no complication due to prematurity in group 2. Postoperative outcome was improved with less need for muscular stretching or prosthetic patch and less re-operation for intestinal obstruction (P < 0.05). Scheduled and elective preterm delivery facilitates surgical procedure and shortens the time to first feeding. A delivery at 35 weeks (preferring vaginal delivery) seems to be a good compromise between risks related to prematurity and complications related to intestinal peel.
