Should we question early feminizing genitoplasty for patients with congenital adrenal hyperplasia and XX karyotype

BACKGROUNDnThere is a wide difference of opinion between the medical-surgical community and advocacy group regarding Disorders of Sexual Development (DSD) secondary to congenital adrenal hyperplasia (CAH) being ranked in the intersex category. This rupture is even more evident when the issue of genitoplasty is brought up. For physicians it is obvious and unequivocal that a person with CAH and an XX karyotype has a female gender identity, whereas associations tend to rank persons with CAH in the intersex category and advocate holding-off on surgical management.nnnMATERIAL/METHODSnA retrospective case study vs. control group, spanning over 40years, included 21 patients who were treated in 3 different centers. Each patient and their parents were contacted independently and interviewed regarding interpersonal relationships, psychological impact of genitoplasty, gender identity and opinion on optimal care management for this disorder. Three couples controls (parent-child) per CAH patients were used and matched according to age, sex assigned at birth and ethnic origin.nnnRESULTSnSex assigned at birth seemed to concord with the gender identity perceived by the patients in 85.7% of cases. In fact, 89.7% of patients and 100% of parents felt that feminizing genitoplasty should be performed within the first year of life. There is however a significant difference compared to controls who felt that surgical management should occur later on in life. No difference was highlighted during childhood regarding parents-child relationships or social integration. However, during adolescence, the parents-child relationship tended to be significantly more painful for the CAH group. Integrating their parenting role was significantly harder for patients in the CAH-DSD group. In the population of CAH-DSD patients who had genitoplasty the level of sexual fulfillment was not lower to the one reported by the control group.nnnCONCLUSIONnFemale sex assignment seems legitimate according to this study and the development of gender identity in these patients matches the sex assigned at birth. Resolving early on the adequacy of the genital anatomy with the sex assigned is promoted by patients as well as their parents. Proper psychomotor development and sexual satisfaction underline the absence of complications related to the surgical technique and the relevance of early surgical management.

Botulinum toxin injections in the management of non-neurogenic overactive bladders in children

INTRODUCTIONnNon-neurogenic detrusor overactivity in children leads to varying degrees of functional impairments (urinary urgency, pollakiuria, urge incontinence, nocturia). Botulinum toxin has shown its effectiveness in the management of detrusor overactivity in neurological patients.nnnOBJECTIVESnTo evaluate the relevance of intravesical Botulinum toxin injections for the treatment of non-neurogenic overactive bladders in children. These pediatric patients were resistant to all the usual therapeutics (e.g. bladder/bowel rehabilitation, anticholinergic drugs, management of diet/hygiene habits and constipation, percutaneous posterior tibial nerve stimulation).nnnMATERIALS AND METHODSn8 children (mean age: 12.5years), 5 girls, 3 boys with daytime and/or nighttime incontinence and non-neurogenic detrusor overactivity validated by urodynamic testing. Urodynamic testing was conducted before the injections as well as 6weeks and 1year post injections. We used Dysport® 8 Speywood Units/kg injected via cystoscopy into 25 different sites.nnnRESULTSnWe noted improvements without any complaints during bladder voiding for all patients, in 6 patients the overactivity disappeared after 1 injection. Compliance was improved early-on in half the cases and at 1year for all cases (from 12% to 61%, p=0.01). Noninhibited contractions decreased constantly in both frequency and intensity. Clinical symptoms improved: mean of 7.75 daytime urinary incontinence episodes (IE) per week before the injection vs. 3 after the procedure (p=0.04). For nighttime IE the improvement was even more noticeable with 7.38 nighttime IE episodes per week before the injection vs. 2.06 after the procedure (p=0,02).nnnCONCLUSIONnIntradetrusor Botulinum toxin injections are a potential therapeutic option for the management of non-neurogenic detrusor overactivity in children resistant to the usual treatments.

Management of refractory overactive bladder in children by transcutaneous posterior tibial nerve stimulation: A controlled study.

OBJECTIVEnTo assess the objective efficacy of transcutaneous posterior tibial nerve stimulation in children presenting with overactive bladder resistant to well conducted treatment.nnnMATERIAL AND METHODnThis was a randomized, double-blind, controlled study on 20 children with OAB. All patients were previously treated with anticholinergic drugs associated with detrusor rehabilitation, diet advice, bladder-voiding hygiene and constipation treatment, with poor clinical results. Patients were randomized into two groups: -Group A: treatment with PTNS (n = 11). -Group B: sham treatment (n = 9). The program lasted 12 consecutive weeks with two 30-minutes sessions a week. Each patient underwent pre-stimulation urodynamic testing to validate bladder overactivity followed by a post-stimulation testing. Pre- and post-stimulation urodynamic parameters were compared in order to objectively evaluate the treatments efficacy. The patients noted their incontinence episodes for 7 consecutive days in a diary before the beginning of the program, in the middle and at the end of it: this led to computing an incontinence score (score ranged from 0 to 13, from good to poor). The difference between the pre-stimulation and post-stimulation score enabled to express clinical results in terms of poor (less than a 3-point decrease), medium (a 3 to 5-point decrease), good (6 to 8-point decrease), very good (final score ranged between 0 and 3). Children were questioned regarding their impression of being stimulated or not.nnnRESULTSnIn Group A, there were five very good clinical results (45%), one medium (10%) and five poor results (45%). In group B, nine very good results (66%) and three poor results (33%) were noted. Regarding urodynamic testing, volume voided during urgency (184 mL to 265 mL), maximal cystomanometry volume (215 mL to 274 mL) and volume at the onset of the first overactive detrusor contraction (ODC) (48 mL to 174 mL) were significantly increased in Group A (p = 0.002, p = 0.024 and p = 0.001) and maximal bladder pressure during ODC had decreased (61 to 46) (p = 0.042). 85% children in group A thought they were being stimulated vs. 70% in group B.nnnCONCLUSIONnEven though we noticed urodynamics improvements in group A, which objectively supports the efficacy of TCTPNS, clinical results remained the same between the two groups. In spite of the small size of our sample, this underlines the placebo effect of any type management in this pediatric population. Studying precisely the maximal useful voltage and duration of stimulation should then be relevant in order to yield maximal benefits from this easy-to-use procedure.

The position of a written document in preoperative information for pediatric surgery: A randomized controlled trial on parental anxiety, knowledge, and satisfaction

INTRODUCTIONnPreoperative information is a legal and ethical obligation. Very little studies have evaluated the preoperative information method in pediatrics. Having a child operated on is stressful for the parents. Improving information is a way to lower their anxiety. Our study aims to measure the impact of a leaflet, which supports spoken information on parental anxiety, the comprehension-memorization of the information and their satisfaction.nnnMATERIALS & METHODSnProspective study including 178 patients of outpatient surgery, randomized in two groups: spoken information versus spoken information supported by a leaflet, which is then handed out to the parents. The messages were identical: physiopathology, risks without treatment, surgical technique and its possible complications, description of the hospitalization day, and postoperative care. Parental evaluation was made with self-questionnaires after the preoperative consultation, then on the day of surgery. At each moment we evaluated the level of anxiety, satisfaction of information quality and the comprehension-memorization of the data.nnnRESULTSnWritten information significantly improves the scores of comprehension-memorization, parental satisfaction and significantly decreases the level of anxiety.nnnCONCLUSIONnSignificant impact of the written document as communication support in pediatric surgery, validating the method and encouraging it to be generalized to other pediatric surgery acts.nnnLEVEL OF EVIDENCEnLevel I.nnnTYPE OF STUDYnPrognosis study.

Article originalPlace du thermalisme en chirurgie plastiqueThe role of balneology in plastic surgery

UNLABELLEDnBalneology can be part of the plastic surgery care sector. The objectives of this study were firstly to the state of knowledge about the hydrotherapy and specify the place reserved for hydrotherapy by surgeons as an adjunct in plastic and reconstructive surgery (adult and child).nnnMATERIALS AND METHODSnMulticentric national study by poll (Google Drive®) focused at plastic and/or pediatric surgeons. The following information was analyzed: frequency, timing of prescription, indications, the surgeons feelings towards hydrotherapy and the differences between adults and childrens prescriptions.nnnRESULTSnFifty-four teams were contacted: 22 responses were received (15 adult plastic surgeons, 9 pediatric plastic surgeons, 6 pediatric surgeons, with 12 out of 22 working with burnt patients). Eighteen out of 22 prescribed hydrotherapy. Twenty out of 22 thought that hydrotherapy had a role as adjuvant therapy in plastic surgery. The indications were: burns (11/20), skin-graft hypertrophy (10/20), inflammatory and pruritic scar and cutaneous trophic disorders (9/20), psychological (3/20), retractions (2/20), weight loss and smoking (1/20). The timing of the prescription was: < 3 months (2/20), < 6 months (7/20), > 6 months and < 1 year (15/20), > 1 year (8/20) after surgery/trauma. Twenty out of 22 found a beneficial effect: physical (19/20): reduction of inflammatory signs, pruritus and pain, scar maturation, skin thinning improvement; psychological (14/20): positive for patient/family. Five out of 17 made the difference between child/adult, 10/17 made no difference but only treated adults or children.nnnCONCLUSIONnThe respondents in the study are probably more sensitive to the effects of hydrotherapy that non-respondents. It is difficult to assess the real impact of hydrotherapy in plastic surgery because distinguishing spontaneous favorable evolution of a scar from one only due to the hydrotherapy or multidisciplinary management is difficult. However, hydrotherapy seems to have its role among multidisciplinary management.

The learning curve of robot-assisted laparoscopic pyeloplasty in children: a multi-outcome approach

INTRODUCTIONnFew studies have evaluated the learning curve (LC) for robot-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction in children. It was attempted to assess the LC of this procedure using a multi-outcome approach, accounting for patient complexity.nnnMATERIAL AND METHODSnData on the first series of children undergoing RALP between November 2007 and December 2017xa0at the study institution were prospectively collected. Patient complexity factors and peri-operative data including operative time (OT) were retrospectively analyzed. The LC was analyzed using cumulative sum (CUSUM) methodology for OT and a composite parameter (combination of 3 parameters: OT adjusted for patient complexity factors (AOT), complications, and surgical success).nnnRESULTSnTwo surgeons without any experience in robotic surgeryxa0performed 42 consecutive RALP in 41 patients. Median age at surgery was 5 years (6 months-15 years), and mean OT was 200xa0±xa072.8xa0min. Cumulative sum chart demonstrated biphasic LC for OT and multiphasic LC for composite factor. Based on the CUSUM analysis for composite outcome, the LC for RALP could be divided into three different phases: phase 1, the learning period (1-12 cases); phase 2, the consolidation period (13-22 cases); and phase 3, representing the period of increased competence (23-39xa0cases). Interphase comparison showed a significant reduction in OT, length of stay, and postoperative pain (Pxa0=xa00.0001; Pxa0=xa00.0076; Pxa0=xa00.039, respectively) CONCLUSION: Numerous distinctly shaped LCs depending on the outcome measures and well-defined learning phase transition points were demonstrated. Patient complexity factors were accounted for, which can influence surgical outcomes. Because there is no perfect indicator of proficiency, a multi-outcome approach was adopted to provide a comprehensive view of the learning process for RALP. More than 41 cases are needed to achieve mastery.

Sonography of suspected acute appendicitis in children: Evaluation of the progress in performance of senior residents

PURPOSEnThe objective of this study was to evaluate the progress in performance of senior residents in diagnosing acute appendicitis.nnnMATERIAL AND METHODSnResults were collected and compared of ultrasound examinations performed for suspected acute appendicitis by three senior residents and two faculty members over a six-month period in a university hospital setting. A grid with the sonographic findings was completed separately by the residents and the faculty members immediately after each examination. The duration of each examination was reported. The final ultrasound diagnosis was compared to the surgical and pathological results and to the clinical follow-up.nnnRESULTSnThe residents and faculty members performed 171 consecutive ultrasound examinations including 49 children with acute appendicitis and 122 with normal appendices. The accuracy of the diagnosis by the residents was 96%, and was similar to that of the faculty members (kappa=0.90) over the six months. The duration of the resident ultrasound examinations was significantly shorter during the second three-month period (p=0.01). No significant differences in diagnostic accuracy were demonstrated by the residents between the first and second three-month periods (p=0.06).nnnCONCLUSIONSnThe residents performed well when using sonography to diagnose acute appendicitis in children, and were faster during the second three-month period.nnnLEVEL OF EVIDENCEnI.

Laparoscopic Pyloromyotomy: A Study of the Learning Curve

Introduction Laparoscopic pyloromyotomy (LPM) is a minimally invasive surgical technique used in pyloric stenosis treatment. This technique is safe, effective, and does not show more complications than laparotomy. Nevertheless, this technique requires an acquisition period to be optimally applied. This study analyses the learning curve of LPM. Materials and Methods Seven surgeons were retrospectively evaluated on their 40 first LPM. Patient data were recorded, including peroperative data (operation length and complications) and postoperative recoveries (renutrition, vomiting, and complications). The learning curves were evaluated and each variable was compared with the different moments of the learning curve. Results The mean operative time is 25 ± 11 minutes. It significantly decreases with the learning curve (p < 0.01). Ten procedures were necessary to acquire the operative technics. However, postoperative complications with a necessary redo procedure appear after the 10th patient. There is no significant difference concerning long‐term postoperative complications according to the learning curve and to surgeons. The best results are recorded after the 20th patients. Hospital length of stay also decreases significantly after the 10th procedure. The recorded postoperative vomiting is independent to the operative time as the ad libitum feedings recovery. Conclusion The learning curve of LPM is cut into three stages. Only 10 cases are needed to acquire the gesture. Complications appear after this acquirement period.

Laparoscopic pyloromyotomy for hypertrophic pyloric stenosis: a survey of 407 children

IntroductionPyloromyotomy is the standard care for hypertrophic pyloric stenosis. The traditional approach for this procedure is a right upper quadrant transverse incision, although other “open” approaches, such as circumumbilical or periumbilical incision have been described. The more recent approach used is laparoscopic pyloromyotomy (LP), but experience feedback is still debated and its benefits remain unproven. The aim of this study was to make a review of all our LP procedures with an objective evaluation according to the literature.MethodsA retrospective analysis of all the LPs performed in one University Children’s Hospital between 1 January 1996, and 30 December 2015 was realized. Information regarding the patient’s status, intraoperative and postoperative data was analyzed.Results407 patients were included in this study. The mean operative time of the overall procedure was 24u2009±u200913xa0min, which significantly increased with the length of the pyloric muscle (pu2009=u20090.004) and significantly impacted the full feeding time (pu2009=u20090.006). 3.4% required conversion to an open procedure during the LP. We observed a significant correlation between conversion for mucosal perforation and weight loss (pu2009=u20090.04) and between conversion for mucosal perforation and preoperative weight (pu2009=u20090.002). A redo procedure was indicated in 3.7%, for incomplete pyloromyotomy each time. The mean postoperative hospital length of stay for all procedures was 1.6u2009±u20090.8xa0days. There were no inflammatory scars. None had incisional hernias or wound dehiscence.DiscussionLP procedure appeared to be as quick as the open procedure. Our results were similar to others series for intraoperative complications. According to operative time, this technique does not have an impact on operative room utilization. Vomiting duration at presentation in HPS does not seem to have a significant impact on postoperative outcomes. LP procedure causes little pain during the postoperative period. No wound complications were registered.
