Surgical management of ovarian masses in children and adolescents: experience of an academic institution in France.

PURPOSE: Surgical management of ovarian masses in girls still challenging. The aim of the study is to report an 8-year experience in managing children with ovarian masses, and to demonstrate the advantages and the limitations of laparoscopy for such lesions. METHODS: Data of girls aged less than 18 years operated because of an ovarian mass between January 2015 and February 2023 were retrospectively reviewed. Patients were divided into two groups: group A including children operated by laparoscopy, and Group B of patients who underwent open surgery. RESULTS: Eighty-eight children were enrolled. Laparoscopy was performed in 56 patients (63.6%). Group A patients had smaller tumor size (53.6±38.5 vs. 122.2±75.4 mm, P<0.0001), shorter operative time (50.4±20.3 vs. 71.5±36.5 min, P = 0.004), reduced length of hospital stay (1.4±1.1 vs. 3±2.3 days, P<0.0001), and absence of postoperative complications. Only 3 cases (5.7%) of recurrence were seen exclusively within patients followed for benign tumors during a mean follow-up period of 4.6±3 years. CONCLUSION: Laparoscopy should be done in benign ovarian lesions or/and if a torsion is seen. For tumors at high risk of malignancy, laparoscopy can be performed to establish a clear macroscopic diagnosis, for staging of the disease, and resection of small tumors. Conversion to open surgery is indicated in case of doubt.

"Double-Lumen Valve-Controlled Intra-Operative Pyeloplasty Stent (VIPs)": A New Technology for Post-Pyeloplasty Stenting - Proof of Concept Study in a Preclinical Large Animal Model.

BACKGROUND: Pyeloplasty is a common surgical operation with a high success rate. However, significant challenges are to be optimized in the design of stenting systems in order to improve perioperative monitoring of urine drainage and enhance patient and family comfort through easier post-operative care. MATERIALS AND METHODS: In a preliminary study in six pigs, handling, mechanical and functional features of this stent system were tested. In our main study, six double-lumen stents (230 mm long each) and 6F/9F external diameter were implanted through the ureteric walls of six domestic pigs to allow postoperative drainage and monitoring following ureteroureterostomy. After a 7-day survival period, monitoring with intravenous antibiotic coverage, and pain control, contrast antegrade pyelogram, under valve control, and renal ultrasonography were conducted and stents explanted and the animals were then euthanized. RESULTS: The double-lumen valve-controlled stent supported the healing of the neo anastomoses and helped to monitor perioperative urine drainage and perianastomotic leakage accurately. It also guided a well-controlled more informative radiological contrast-supported imaging before removal of the stents that confirmed the healing of the neo anastomotic site and no leak formation. The double-lumen system demonstrated high feasibility regarding its insertion, functionality, and removal capacities. The excellent flexibility of the individual stents allowed exact anatomically controlled implantation. CONCLUSION: The double-lumen valve-controlled stent system was studied in a porcine model, which demonstrated its feasibility. Preclinical experience revealed favorable results concerning stent implantation, operability and functionality, in the perioperative management of pyeloplasty or ureteric surgery.

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.

Intestinal Malrotation and Volvulus in Neonates: Laparoscopy Versus Open Laparotomy.

BACKGROUND: Intestinal malrotations with midgut volvulus are surgical emergencies that can lead to life-threatening intestinal necrosis. This study evaluates the feasibility and the outcomes of laparoscopic treatment of midgut volvulus compared with classic open Ladd's procedure in neonates. MATERIALS AND METHODS: The medical records of all neonates with diagnosis of malrotation and volvulus, who underwent surgery between January 1993 and January 2014, were reviewed. We considered the group of neonates laparoscopically treated (Group A, n = 20) and we compared it with an equal number of neonates treated with the classical open Ladd's procedure (Group B, n = 20). RESULTS: The median age at surgery was 8.4 days and the mean weight was 3.340 kg. The suspicion of volvulus was documented by plain abdominal radiograph, upper gastrointestinal contrast study, and/or ultrasound scanning of the mesenteric vessels. All the patients were treated according to the Ladd's procedure. Conversion to an open procedure was necessary in 25% of the patients. The mean operative time was 80 minutes (28-190 minutes) in Group A and 61 minutes (40-130 minutes) in Group B (P = .04). The median time to full diet (P = .02) and hospital stay (P = .04) was better in Group A. Rehospitalization because of recurrence of occlusive symptoms occurred in 30% of patients in Group A (n = 6) and in 40% of patients in Group B (n = 8). Among these, all the 6 patients of Group A underwent redo surgery for additional division of Ladd's bands or debridement; instead in Group B, 4 of 8 patients underwent open redo surgery. CONCLUSIONS: Laparoscopic exploration is the procedure of choice in case of suspicion of intestinal malrotation and volvulus. Laparoscopic treatment is feasible and safe even in neonatal age without additional risks compared with classical open Ladd's procedure.

Long-term functional renal outcomes after retroperitoneoscopic upper pole heminephrectomy for duplex kidney in children: a multicenter cohort study.

BACKGROUND: Retroperitoneoscopic upper pole heminephrectomy (RUHN) in duplex kidney in children remains a challenging procedure with a need for postoperative functional assessment of the remnant lower pole. We aimed to calculate the incidence of long-term functional renal outcomes in these children and examine the effect of age on those outcomes. METHODS: A multicenter retrospective cohort study of 9 years included all patients undergoing RUHN and evaluated by renal ultrasound (US) and dimercaptosuccinic acid (DMSA) scintigraphy pre and postoperatively. Patients were divided in two age groups of ≤12 and >12 months. Standard follow-up assessed pre-, intra- and postoperative outcomes using clinical review, US and DMSA. RESULTS: Standard RUHN in lateral position was performed in 30 patients. Five cases were excluded (2 lacks of postoperative DMSA, 3 conversions). Indications for RUHN were non-functioning upper moieties (n = 25) caused by ureterocele (n = 11), ectopic distal implantation of the ureter with incontinence (n = 6) or evolving severe ureterohydronephrosis (n = 8). Mean age at surgery was 30 ± 27 months, operation time 116 ± 52 min and hospital stay 2.8 ± 1 days. Long-term follow-up (mean, 7.2 ± 2.7 years) with US and DMSA showed that none of the 25 patients had complete loss of lower pole renal function. Mean lower pole renal function directly related to RUHN was not significantly different after versus before RUHN for the entire cohort (n = 24; 39.7 ± 7.90 % vs. 41.7 ± 6.74 %; p = 0350), for the ≤12-month (n = 6; 39.3 ± 4.18 vs. 41.3 ± 5.47; p = 0.493) and the >12-month groups (n = 18; 39.8 ± 8.90 vs. 41.9 ± 7.25; p = 0.443). Four patients (17 %) had partial loss of function (mean function loss, 9.3 ± 5.85 %; median age, 13 months). The number and type of complications between the two age groups were not statistically different. Overall, 29 % (n = 7/24) of the patients presented with medium-term (17 %) and long-term (17 %) complications directly related to RUHN. CONCLUSIONS: RUHN is a demanding yet efficient technique that is safe for the lower pole at any age. Systematic postoperative DMSA is not mandatory as long as US remains normal.

Two-year outcomes after diagnostic and therapeutic fetal cystoscopy for lower urinary tract obstruction.

OBJECTIVES: Our objective is to report long-term outcome after fetal cystoscopy for lower urinary tract obstruction (LUTO), as well as to investigate the accuracy of fetal cystoscopy in diagnosing the cause of bladder outlet obstruction. METHODS: This is a retrospective cohort study of all fetuses who underwent cystoscopy for prenatal diagnosis of LUTO in three tertiary referral centers. Fetal diagnostic cystoscopy was performed to determine prenatally the cause of LUTO and to ablate the posterior urethral valves (PUV). RESULTS: A total of 50 fetal cystoscopies were performed, revealing PUV in 31 (62%) fetuses, urethral atresia (UA) in 14 (28%) fetuses, and urethral stenosis (US) in 5 (10%) fetuses. Two fetuses had trisomy 18 diagnosed after fetal cystoscopy and were excluded from the present analysis. Fetal cystoscopy was accurate in the diagnosis of the etiology of LUTO in 32/35 (91.4%). There were no survivors in the UA group. One fetus with US underwent urethral stenting and survived with normal renal function at 2 years of life. Among the infants with PUV, 17/30 (56.7%) infants survived, and 13/17 (76.5%) had normal renal function at 1 year of life; 15/28 (53.6%) infants survived, and 11/15 (73.3%) had normal renal function at 2 years. CONCLUSIONS: Fetal cystoscopy is accurate in the diagnosis of the etiology of LUTO and serves as a guide to the specific prenatal treatment. This procedure is associated with modest long-term survival (54%) but with adequate preserved normal renal function in two thirds of the infants among fetuses with PUV.

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.

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.

Endoscopic Mic-Key button placement for continent vesicostomy.

INTRODUCTION: The use of a gastrostomy button for intermittent emptying of the bladder has been already proposed. The aim of this study was to describe a percutaneous button placement under endoscopic control as a safe, minimally invasive technique. MATERIALS AND METHODS: The percutaneous gastrostomy kit, according to the Russell gastrostomy tray (Cook; Cook, Bloomington, IN), was used under cystoscopic control. The U-stitche technique, according to Georgeson, allowed us to secure the bladder to the abdominal anterior wall. A guide was introduced into the bladder through a needle. Three dilatators, respectively 12, 14, and 16 FR, allowed the path for a probe or, immediately, the gastrostomy button (Mic-Key; Ballard Medical Products, Draper, UT). RESULTS: Over 2 years, 10 percutaneous continent vesicostomies were performed for patients with a neurogenic bladder. Patients were from 5 months to 19 years old. The procedure was safe. No major complication was observed except for only minor ones. DISCUSSION: When intermittent urethral catheterization cannot be established, Mitrofanoff continent urinary diversion seems to be a major surgery for patients and their parents. In addition, for some patients, intermittent bladder emptying may be required for a transitory period. For all these reasons, there is a place for a reversible vesicostomy with a minimally invasive procedure. Button vesicostomy seems to be a good alternative. In this article, we propose a percutaneous technique with an endoscopic control. If this kind of treatment is effective, it may avoid further major surgery. CONCLUSIONS: Percutaneous button vesicostomy placement under endoscopic control is safe and feasible and must be evaluated with large series.

Botulinum toxin-A (Botox) intradetrusor injections in children with neurogenic detrusor overactivity/neurogenic overactive bladder: a systematic literature review.

OBJECTIVES: Describe and discuss the efficacy and safety of botulinum toxin type A (BTX-A) intradetrusor injections in children with neurogenic detrusor overactivity (NDO) and urinary incontinence or overactive bladder symptoms of neurogenic origin (NOAB). METHODS: A MEDLINE and EMBASE search for clinical studies involving BTX-A injected into the detrusor of children with NDO or NOAB was performed, prior to data analysis. RESULTS: A total of six articles evaluating the efficacy and safety of Botox in patients with NDO and incontinence/NOAB were selected. The underlying neurological disease was myelomeningocele in 93% of patients. Most were over 2 years of age. The most common amount of Botox injected was 10-12 U/kg with a maximal dose of 300 U, usually as 30 injections of 10 U/ml in the bladder (excluding the trigone) under cystoscopic guidance and general anaesthesia. Most of the studies reported a significant improvement in clinical (65-87% became completely dry) as well as urodynamic (in most studies mean maximum detrusor pressure was reduced to <40 cm H(2)O and compliance was increased >20 ml/cm H(2)O) variables, without major adverse events. CONCLUSIONS: Botox injections into the detrusor provide a clinically significant improvement and seem to be very well tolerated in children with NDO and incontinence/NOAB refractory to antimuscarinics.

Laparoscopic pyeloplasty for repair of pelviureteric junction obstruction in children.

PURPOSE: The aim of this study was to report our initial experience with laparoscopic pyeloplasty (LP) in children with pelviureteric junction (PUJ) obstruction and describe the evolution and evaluate the results. MATERIALS AND METHODS: We retrospectively reviewed the records of 32 consecutive infants and children with unilateral ureteropelvic junction obstruction and deterioration of renal function on isotope renography, who underwent LP (19 on the right, 13 on the left) between May 2003 and January 2007. Twenty-three were males and 9 females. The mean age was 7.7 years old (range, 2 months to 17 years); the patient was placed in a three quarter lateral position and three ports were used. The PUJ was resected and the anastomosis was made by using absorbable sutures. A JJ stent was inserted by laparoscopy in most patients. Follow-up included clinical and ultrasound assessment, followed by isotopic renography at 6 months. RESULTS: LP was feasible in 29 of 32 patients (91%). The procedure could not be completed by laparoscopy in 3 patients; the main reason was difficulty in completing the anastomosis. Only 1 patient with a big redundant renal pelvis underwent a reduction. Stent insertion was successful in all, except 1 patient. An aberrant crossing vessel was found in 12 patients. We held up the aberrant crossing vessel and PUJ with two- or three-point-not absorbable-sutures, without the needed pyeloplasty in 2 of them. The other 10 underwent a LP enabled ureteric transposition. Three patients presented with postoperative complications: pyelonephritis in 2 patients and PUJ leakage in 1 who underwent nephrostomy with a further uneventful course. Mean operative time was 152 minutes (range, 120-270), and average hospital stay was 4.7 days (range, 1-8). In 1 patient, cystoscopy showed that the JJ stent was not in the bladder at the time of removal, and ureteroscopy was used to retrieve it. Mean follow-up was 22 months (range, 2-56). A total of 29 patients (91%) were asymptomatic after removal of the double JJ stent, showing a reduction of the degree of hydronephrosis in all patients, and had also improved PUJ drainage on isotope renography or sonography. CONCLUSIONS: LP is effective and safe in children with minimal morbidity and gives excellent short-term results. The feasibility is also excellent in patients younger than 1 year. The transabdominal approach revealed good exposition without disadvantages for the patient.

Autologous adipocyte graft in endoscopic treatment of vesico-renal reflux in children: a preliminary study.

No bulking agent is ideal for endoscopically treating vesico-renal reflux in children. Many teams have tried to find a safe and efficient material, ideally an autologous material. We describe here a protocol for the use of autologous viable fat in the treatment of primary vesico-renal reflux in children aged from 3 to 15 years. Fat harvesting was done from the medial side of the thigh by manual aspiration. Samples were centrifuged to purify the graft from blood and lipid. Lastly fat was injected beneath the pathologic ureter by a conventional endoscopic technique. A voiding cystourethrography (VCUG) closed the procedure. Follow-up included renal ultrasonography the day after surgery, and one and three months later. A VCUG was performed systematically at three months and, in cases of acute pyelonephritis, during the survey.Sixty-four children with 94 refluxing units were treated by autologous fat injection with a follow-up from 6 to 40 months. At the end of the procedure, we systematically obtained a very good increase in height of the pathologic meatus and VCUG was normal in all cases. None presented with an obstruction during the follow-up period. Two children presented with an acute pyelonephritis before the third month. At three months, VCUG was not realized in 14 cases (22%) because the parents refused the procedure. One of those children presented with an acute pyelonephritis five months after endoscopic treatment. VCUG was normal for 17 of 50 children (34%), and showed a real improvement for 19 other children (38%). Three children had a surgical reimplantation because of the persistence of an unchanged high-grade vesico-renal reflux; histological examination found viable adipocytes on sections of the distal pathologic ureter. Clinically, 11 children (17%) presented with an acute pyelonephritis after treatment at a mean follow-up time of 10 months.These preliminary findings led us to modify the technique in order to improve our results. Our first concern is feasibility and safety of this technique, regardless of the use of other synthetic bulking agents the innocuousness of which is uncertain.

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.

Thoracoscopic repair of congenital diaphragmatic hernia in children.

Minimal invasive surgery (MIS) has been first proposed in case of delayed congenital diaphragmatic hernia (CDH). Since then, about 32 cases of thoracoscopic CDH approach in newborns have been published. Conditions of thoracoscopy are reviewed and enlightened with our preliminary series. The advantages of thoracoscopy versus a laparoscopic approach are detailed. Since 1999, all children presenting with CDH after the immediate neonatal period were offered a MIS approach. We started treating stable newborns suffering a CDH by thoracoscopic procedures in 2003. In cases of late presentations, 10 thoracoscopies and 1 laparoscopy were performed. Among them, 4 patients suffered from an incarcerated hernia. One conversion to a thoracotomy, 1 video-assisted thoracic surgery (VATS), and 2 conversions to laparoscopies were required for the reduction of hernia contents. In those last cases, the hernia defects were sutured, coming back to the thoracoscopic approach. Six newborns with neonatal diagnosis of CDH were primarily treated by thoracoscopy. Four procedures were completed without difficulty. The diaphragm was approximated with interrupted 2/0 nonabsorbable sutures. On the lateral part of the defect, in which there is a lack of diaphragm against the ribs, plegetted rib-anchoring stitches were used. A wide defect requiring a patch needed for conversion to a thoracotomy; in this case, we encountered a very rare pericardial defect and had difficulties in reducing the liver. In another case, we went to a VATS with a less than 2-cm opening to insert a Gore Tex patch, which was required. Thoracoscopy for delayed CDH repair seems to be easy and feasible with good results. A combined procedure with both thoracoscopy and laparoscopy has proven its usefulness in case of incarcerated hernia. Thoracoscopic CDH repair in newborns is not feasible in every case due to the patient's conditions. Criteria for eligibility need more cases to be evaluated. The advantages and disadvantages of thoracoscopy versus laparoscopy are reviewed. Nevertheless, the thoracoscopic approach seems easier.

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.

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.

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.

[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.

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.
