Our Laparoscopic Surgical Technique and Experience in Treating Pediatric Inguinal Hernia Over the Past Decade.

BACKGROUND: Over the past decade, laparoscopic hernia repair was the most performed operation in our department. Equally, it compromises 15% of all pediatric operations performed. We aim, in this study, to review all the cases performed and extrapolate important information like reoccurrences, the incidence of metachronous inguinal hernia, complications amongst other information. MATERIAL AND METHODS: All patients under the age of 18 whom underwent elective laparoscopic hernia repair between 03/01/2007 till the 18/05/2016 were included in our study. We recorded important clinical features and studied their post-operative follow up. Equally reoccurrences, the incidence of metachronous inguinal hernia, complications and other parameters were recorded and studied. RESULTS: A total of 916 patients were operated on during the defined study period. There was a 0.17% reoccurrence rate and a 0.46% incidence of metachronous inguinal hernia. Equally a contralateral patent processus vaginalis was diagnosed and closed in 17.10%. There were no postoperative complications and we had a 0% postoperative hydrocele rate. CONCLUSION: Laparoscopic hernia repair is safe and carries all the benefits of minimally invasive surgery. We recommend that it is offered to patients and would like to refute previously claimed reports that it carries a higher reoccurrence rate or takes a long time to perform. Our reoccurrence rate of 0.17% is actually lower than many published reoccurrence rates after open repair.

Relational development in children with cleft lip and palate: influence of the waiting period prior to the first surgical intervention and parental psychological perceptions of the abnormality.

BACKGROUND: The birth of a child with a cleft lip, whether or not in association with a cleft palate, is a traumatic event for parents. This prospective, multidisciplinary and multi-centre study aims to explore the perceptions and feelings of parents in the year following the birth of their child, and to analyse parent-child relationships. Four inclusion centres have been selected, differing as to the date of the first surgical intervention, between birth and six months. The aim is to compare results, also distinguishing the subgroups of parents who were given the diagnosis in utero and those who were not. METHODS/DESIGN: The main hypothesis is that the longer the time-lapse before the first surgical intervention, the more likely are the psychological perceptions of the parents to affect the harmonious development of their child. Parents and children are seen twice, when the child is 4 months (T0) and when the child is one year old (T1). At these two times, the psychological state of the child and his/her relational abilities are assessed by a specially trained professional, and self-administered questionnaires measuring factors liable to affect child-parent relationships are issued to the parents. The Alarme Détresse BéBé score for the child and the Parenting Stress Index score for the parents, measured when the child reaches one year, will be used as the main criteria to compare children with early surgery to children with late surgery, and those where the diagnosis was obtained prior to birth with those receiving it at birth. DISCUSSION: The mental and psychological dimensions relating to the abnormality and its correction will be analysed for the parents (the importance of prenatal diagnosis, relational development with the child, self-image, quality of life) and also, for the first time, for the child (distress, withdrawal). In an ethical perspective, the different time lapses until surgery in the different protocols and their effects will be analysed, so as to serve as a reference for improving the quality of information during the waiting period, and the quality of support provided for parents and children by the healthcare team before the first surgical intervention.

Laparoscopic splenopexy for a wandering spleen in a child.

We present a case of acute volvulus of a wandering spleen in a 5-year-old girl that was diagnosed preoperatively by computed tomography scan and which we treated with a laparoscopic splenopexy on an emergent basis.

Evaluation of success of alveolar cleft bone graft performed at 5 years versus 10 years of age.

BACKGROUND AND PURPOSE: Although alveolar cleft bone grafting is the most widely accepted approach, controversies remain on the operative timing. METHODS: A consecutive retrospective series of 28 patients who received alveolar bone grafting was examined and divided into 2 groups depending on the age at the time of bone graft. Group A (14 patients) was operated at a mean age of 5.2 years [range, 4-7] and Group B (14 patients) at a mean age of 10 years [range, 8.5-13]. All the children were assessed clinically and by Cone Beam Computed Tomography (CBCT) before bone grafting and 6 months post-operatively. Cleft and bone graft dimensions, volumes were assessed using Osirix v.3.9.2. Residual bone graft coefficient (Bone Graft Volume on 6-months Postoperative CBCT/Alveolar Cleft Volume) was calculated. Complications, tooth movement or dental agenesis were also reported. RESULTS: The sample was uniform within both groups, considering cleft forms, pre-surgical fistula rate and cleft volume. Residual bone graft coefficient reached 63.3% in Group A and 46.2% in Group B (p = 0.012). Results of residual bone graft are also influenced by tooth eruption through the graft (p = 0.007 in Group A and p = 0.02 in Group B). CONCLUSIONS: This 3D analysis highlighted higher success of alveolar bone grafts when children are operated earlier around 5 years. LEVEL OF EVIDENCE: Therapeutic study. Level III/retrospective comparative study.

Evaluation of 5-year-old children with complete cleft lip and palate: Multicenter study. Part 2: Functional results.

BACKGROUND AND PURPOSE: Cleft surgery is marked by all the controversies and the multiplication of protocols, as it has been shown by the Eurocleft study. The objective of this pilot study is to start a comparison and analyzing procedure between primary surgical protocols in French centers. METHODS: Four French centers with different primary surgical protocols for cleft lip and palate repair, have accepted to be involved in this retrospective study. In each center, 20 consecutive patients with complete cleft lip and palate (10 UCLP, 10 BCLP per center), non syndromic, have been evaluated at a mean age of 5 [range, 4-6]. In this second part, maxillary growth and palatine morphology were assessed on clinical examination and on dental casts (Goslon score). Speech was also evaluated clinically (Borel-maisonny classification) and by Aerophonoscope. RESULTS: Veau-Wardill-Killner palatoplasty involves a higher rate of transversal maxillary deficiency and retromaxillary. The fistula rate is statistically lower with tibial periosteum graft hard palate closure but this technique seems to give retromaxillary. Malek and Talmant two-stage-palatoplasty techniques reach Goslon scores of 1 or 2. Considering speech, Sommerlad intravelar veloplasty got higher outcomes. CONCLUSIONS: Primary results. Extension to other centers required. The two-stage palatoplasty, including a Sommerlad intravelar veloplasty seems to have the less negative impact on maxillary growth, and to give good speech outcomes. LEVEL OF EVIDENCE: Therapeutic study. Level III/retrospective multicenter comparative study.

Twenty years' experience for reduction of ileocolic intussusceptions by saline enema under sonography control.

BACKGROUND: Ultrasonography is a well-established efficient diagnostic tool for ileocolic intussusceptions in children. It can also be used to control hydrostatic reduction by saline enemas. This reduction method presents the advantage of avoiding radiations. Parents can even stay with their children during the procedure, which is comforting for both. The purpose of this study was to present our 20 years' experience in intussusception reductions using saline enema under ultrasound control and to assess its efficiency and safety. MATERIAL AND METHODS: This retrospective single center study included patients with ileocolic intussusceptions diagnosed by ultrasound between June 1993 and July 2013. We excluded the data of patients with spontaneous reduction or who underwent primary surgery because of contraindications to hydrostatic reduction (peritonitis, medium or huge abdominal effusion, ischemia on Doppler, bowel perforation). A saline enema was infused into the colon until the reduction was sonographically confirmed. The procedure was repeated if not efficient. Light sedation was practiced in some children. RESULTS: Eighty-tree percent of the reductions were successful with a median of 1 attempt. Reduction success decreased with the number of attempts but was still by 16% after 4 attempts. The early recurrence rates were 14.5%, and 61.2% of those had a successful second complete reduction. Forty-six patients needed surgery (11 of them had a secondary intussusception). Sedation multiplies success by 10. In this period, only one complication is described. CONCLUSION: Ultrasound guided intussusception reduction by saline enema is an efficient and safe procedure. It prevents exposure of a young child to a significant amount of radiation, with similar success rate. We had very low complication rate (1/270 cases or 3‰). The success rate could be increased by standardized procedures including: systematic sedation, trained radiologists, accurate pressure measurement, and number and duration of attempts.

Evaluation of 5-year-old children with complete cleft lip and palate: Multicenter study. Part 1: Lip and nose aesthetic results.

BACKGROUND AND PURPOSE: Cleft surgery is marked by all the controversies and the multiplication of protocols, as it has been shown by the Eurocleft study. The objective of this pilot study is to start a comparison and analyzing procedure between primary surgical protocols in French centers. METHODS: Four French centers with different primary surgical protocols for cleft lip and palate repair, have accepted to be involved in this retrospective study. In each center, 20 consecutive patients with complete cleft lip and palate (10 UCLP and 10 BCLP per center), non syndromic, have been evaluated at a mean age of 5 [4,6]. In this first part, the aesthetic results of nose and lip repair were assessed based on the scale established by Mortier et al. (1997). RESULTS: Considering nose outcome, primary cleft repair surgery including a nasal dissection gives a statistically significant benefit in terms of septum deviation. Considering lip result, muscular dehiscence rate is significantly higher in BCLP patients with a two-stage lip closure. The centers using Millard one-stage lip closure do not have uniform results. For UCLP patients, the quality of scar is not statistically different between Skoog and Millard techniques. CONCLUSIONS: Primary results based on a simple, reproducible evaluation protocol. Extension to other centers required. LEVEL OF EVIDENCE: Therapeutic study. Level III/retrospective multicenter comparative study.

[Original dorsal plasty of the glans in distal hypospadias]. / Plastie dorsale originale du gland dans l'hypospadias distal "Restitutio".

UNLABELLED: The long-term follow-up of patients operated for hypospadias often reveals progressive recession of the neo-meatus, even when it is initially correctly situated. MATERIAL AND METHOD: To overcome this disadvantage, we decided to prolong the glanular groove by longitudinally incising the distal quarter of the dorsal surface of the glans. Transverse suture then defines the margins of the neo-meatus, creates or deepens the glanular groove and promotes the formation of a thick anterior wall which deeply covers a short triangular Mathieu flap. The foreskin is systematically reconstructed. Bladder drainage is ensured by an urethral stent attached to the glans for 7 days. Treatment can now be performed as an outpatient procedure. From 1992 to June 2002, 374 children, with a mean age of 25 months (range: 10 to 129 months) were treated by this technique, with foreskin reconstruction in 307 cases. The preoperative position of the meatus was posterior glanular in 31 cases (83%), peno-glanular in 191 cases (52%) and anterior penile in 152 cases (40.7%). RESULTS: All patients were reviewed with a mean follow-up of 19 months (range: 1 to 123 months). The position of the meatus was normal apical in 309 cases (82.6%): glanular: middle: 41 cases (11%); posterior: 14 cases (17%), peno-glanular: 1 case, dorsal: 6 cases (1.6%), not specified: 3 cases (tight phimosis). COMPLICATIONS: 25 fistulas (6.7%), 4 stenoses (1.1%). DISCUSSION: The usual glanular urethroplasty, by simple suture of the margins, often results in a large meatus situated in the middle of the glans. When the meatus is placed below the glans, recession can lead to an anterior penile meatus. Dorsal glanuloplasty, by elongating and deepening the glanular groove, while preserving the urethral plate, allows the construction of a solid wall around the neourethra, reducing the risks of recession and enlargement of the meatus which retains a split-like appearance and ensures a good stream. Systematic foreskin reconstruction probably also plays a role in the quality of healing. CONCLUSION: This dorsal glanuloplasty, which corrects the penis and urinary stream in more than 80% of cases without any major disadvantages, is a useful technique in hypospadias repair.

Thoracoscopic treatment of congenital diaphragmatic eventration in children: lessons learned after 15 years of experience.

INTRODUCTION: We present our experience with the thoracoscopic treatment of congenital diaphragmatic eventration (CDE) in children through 15 years to evaluate the efficiency of the procedure and the potential risk of recurrence. Materials and METHODS: We reviewed the medical files of patients treated for CDE through thoracoscopy from 2000 to 2011. Age at surgery, sex, side of the lesion, procedure's details, postoperative course, and complications were analyzed. Mean follow-up was 12 months. RESULTS: In this study, eight patients (five males and three females) aged from 6 months to 7 years underwent thoracoscopic plication for six right and two left eventrations; one conversion was necessary due to a too small operative field. Mean operative time was 60.5 minutes. A chest drainage was placed in six patients. We observed two recurrences from which the first one was treated thoracoscopically by endostapler resection/suturing and the other one by laparotomy. At follow-up, all patients were asymptomatic with a correct level of the diaphragm. CONCLUSIONS: Thoracoscopic plication is feasible and safe, and we consider this approach as the gold standard for the treatment of CDE. However, we still need to carefully consider the possibility of introducing certain modifications to reduce the potential risk of recurrence.

Button cystostomy for bladder drainage: which children can benefit from this device?

AIM: The aim of this study is to define which children could benefit from a button cystostomy. We describe a safe way to perform the insertion of a button cystostomy for urinary diversion and provide more precise instructions concerning the best indications for this device. MATERIALS AND METHODS: We analyzed several criteria of the follow-up of all the patients who had a button cystostomy since 2007 including indications, age, urodynamic variables, and complications. RESULTS: Twenty-one patients underwent a button cystostomy. A group of young children was included in the study (mean age, 2 years), in which most of the failed procedures were observed, whereas we had better results with the second group of older children (mean age, 12 years). CONCLUSIONS: The analysis of indications and, more particularly, urodynamic variables regarding the quality of the results allows us to clearly define which children can benefit from this procedure with a good chance of success and low risk of complications.

Cecostomy button for antegrade enemas: survey of 29 patients.

OBJECTIVE: This study evaluated the Trap-door button use (Cook Medical, Bloomington, IL) for antegrade enemas in children. METHODS: Since 2002, patients with fecal incontinence or encopresis and constipation underwent percutaneous cecostomy under laparoscopy using a button. Technical details are described. Age at surgery, operative time, hospital stay, diagnosis, indications for cecostomy, and duration of follow-up were recorded. A survey was proposed via a questionnaire that was sent to the patients. Patients wearing the button for less than 1 month were excluded from this evaluation. The survey concerned volume and frequency of enemas, difficulties encountered, benefits and disadvantages of this method, and assessment of the antegrade enemas in continence. RESULTS: Twenty-nine patients, 18 males and 11 females, aged 3 to 21 years (mean, 8.5 years) underwent laparoscopic Trap-door button placement. The indications for all the patients were intractable fecal incontinence in 24 cases and constipation with encopresis in 5 cases. Incontinence was because of myelomeningocele (n = 10), anorectal malformations (n = 11), caudal regression syndrome (n = 1), 22q11 syndrome (n= 1), and Hirschsprung disease with encephalopathy with convulsions (n = 1). Constipation with encopresis was because of sacrococcygeal teratoma (n = 1), cerebral palsy (n = 1), and acquired megarectum with psychiatric and social disorders (n = 3). A total of 26 cecostomy button placements and 3 sigmoidostomy button placements were successful with no intraoperative complication. The mean operative time was 25 minutes (10-40 minutes), and the hospital stay was 2.5 days (1-4 days). Twenty-two parents or patients answered the questionnaire. At the time of this survey, 2 patients had improved their fecal continence and had had the button removed. A mean of 4 weekly enemas was enough to improve fecal continence troubles (range, 1 daily to 1 for 2 weeks). The volume for enemas was 250 to 1000 mL (mean, 700 mL). The time required for the irrigation of the bowel by gravity took from 5 to 60 minutes (mean, 25 minutes) for 20 patients. Before surgery, 14 patients needed a diaper, day and night, and 6 needed sanitary protection. Soiling was a very significant inconvenience for all the patients. After surgery, only 5 patients needed a diaper (cerebral palsy, 22q11, cloacal malformation, myelomeningocele, bladder exstrophy) because of moderate results or urinary incontinence and continued soiling. Patients were asked to give an assessment (null = 0, bad = 1, fair = 2, good = 3, very good = 4). None of the patients felt there had been no changes or a bad result. There were 5 patients who felt they had an average result, 5 a good result, and 12 a very good result. The mean grade was 3.44 (17.2/20). A total of 3 patients had hypertrophic granulation tissue formation around the cecostomy button, and 12 had tiny leakage. CONCLUSION: Percutaneous placement of a cecostomy button under laparoscopic control is an easy and major complication-free procedure. The use of the Trap-door device by the patients or with the help of the parents for antegrade enemas is effective and satisfactory. It improves the quality of life and is reversible.

Sertoli cell tumor of the testis in children: reevaluation of a rarely encountered tumor.

Testis tumors are uncommon in childhood, and they differ from adult tumors in terms of histology and frequency. Sertoli cell tumors appear in children before 1 year of age. They are more frequently benign, but because of the absence of specific signs of malignancy, treatment consists of radical orchiectomy, sometimes followed by radiotherapy or chemotherapy based on histologic analysis. Malignancy is confirmed by the presence of metastasis or many mitosis and anaplastic cells. Children must be followed for several years to be sure of the absence of relapse or progression. In the authors' hospital, of 13 testis tumors diagnosed since 1996, only 2 were Sertoli cell tumors. It would be helpful to have an algorithm for the management of testis tumors, outlining how to make the diagnosis of malignancy and which treatment and follow-up to pursue.

Thoracoscopic diaphragmatic eventration repair in children: about 10 cases.

BACKGROUND AND AIM: Recent reports in literature have emphasized the clinical perception of reduced pain, postoperative morbidity, and dysfunction associated with thoracoscopic approach compared with standard thoracotomy. The authors describe a thoracoscopic approach and technical details for diaphragmatic eventration repair in children. PATIENTS AND METHODS: Ten patients, 4 girls and 6 boys, 1 teenager (14 years old) and 9 children (age range, 6-41 months; average, 17 months), were operated for a diaphragmatic eventration in 3 different pediatric surgery teams, according to the same technique. Symptoms were recurrent infection (7 cases), dyspnea on exertion (2 cases), and a rib deformity (1 case). An elective thoracoscopy was performed, patient in a lateral decubitus. A low carbon dioxide insufflation allowed a lung collapse. Reduction of the eventration was made progressively when folding and plicating the diaphragm. Plication of the diaphragm was done with an interrupted suture (6 cases) or a running suture (4 cases). The procedure finished either with an exsufflation (4 cases) or a drain (6 cases). RESULTS: A conversion was necessary in 2 cases: 1 insufflation was not tolerated and 1 diaphragm, higher than the fifth space, reduced too much the operative field. Patients recovered between 2 and 4 days. Dyspnea disappeared immediately. Mean follow-up of 16 months could assess the clinical improvement in every patient. DISCUSSION: Thoracoscopic conditions are quite different between a diaphragmatic hernia repair previously reported and an eventration. Concerning diaphragmatic hernias, reduction is easy, giving a large operative space for suturing the diaphragm. Concerning diaphragmatic eventrations, the lack of space remains important at the beginning of the procedure despite the insufflation into the pleural cavity. The operative ports must be high enough in the chest to allow a good mobility of the instruments. Chest drainage seems to be unnecessary. CONCLUSION: Diaphragmatic eventration repair by thoracoscopy is feasible, safe, and efficient in children. Above all, it avoids a thoracotomy. It improves the immediate postoperative results with a good respiratory function.

Is one-stage ureterocele repair possible in children?

AIM: To determine the long-term results of ureterocele repair, bearing in mind the relative rarity of the malformation, its very polymorphic appearance and the diversity of treatments. MATERIALS AND METHODS: Long-term results were assessed by postoperative follow-up of 126 children with 131 ureteroceles between 1970-2000. RESULTS: With a mean follow-up of 72 months, only 64.2% of children were cured after a one-stage procedure. According to the anatomical type, favourable results were obtained in 81.6% of cases with a single ureter and 57.9% of cases with a duplicated ureter. Treatment success rates for single or duplicated ureters were 73% in the case of intravesical implantation and only 53.9% (34/63 children) in ectopic forms. According to the technique, cure rates were 67.6% after distal incision in 34 children, 61.9% after total nephrectomy or upper pole nephrectomy in 42 children, 50% after ureterocele repair and ureterovesical reimplantation in 20 patients, 75% after total resection of the pathological ureter, parietal reconstruction and ipsilateral and/or contralateral reimplantation in another 20 patients. CONCLUSIONS: A one-stage procedure is only able to cure 2/3 of patients. In view of the tendency to progressive regression of often monstrous distensions during the neonatal period, first-line treatment should consist of a distal incision, followed, in the case of recurrent infections, by partial or total nephrectomy, while reserving the intravesical approach to cases with recurrent pyelonephritis. When this surgery is performed on older children or adolescents, the ureteroceles will be smaller with a lower risk of sphincter damage.
