[Spermatic cord torsion in children].

OBJECTIVES: Definition of prognostic factors for torsion of the testis in children. MATERIAL AND METHODS: From January 1986 to December 1996, 91 children were operated for torsion of the testis. Torsions were observed at all ages of childhood, but with two frequency peaks: during the neonatal period and in adolescence. Typical clinical features were observed in only three-quarters of cases. RESULTS: Thirty-nine testes were considered to be necrotic versus 52 with a chance of recovery. Factors of poor prognosis were: neonatal forms, delayed management or tight torsion with several turns. 28 of the necrotic testes were conserved: two were complicated by purulent necrosis, but 14% retained normal trophicity on long-term examination. CONCLUSION: The possibility of torsion at all ages of childhood and the frequently incomplete clinical features means that emergency surgical exploration must always be performed in the case of testicular pain. A conservative attitude is motivated by the possibility of recovery of testes considered to be necrotic at operation.

[Intestinal stenosis during ulceronecrotizing enterocolitis].

BACKGROUND: Intestinal stenosis following necrotizing enterocolitis (NE) occurred both in surgically-treated neonates after perforation, distal to an enterostomy and in medically-treated patients developing symptoms of obstruction. It has been proposed to detect stenosis by contrast enema before refeeding in those medically-treated patients. The aim of this study was to compare delay, clinical and pathological characteristics of surgical and medical patients, both after occlusion and prospective contrast studies. PATIENTS AND METHODS: Fifteen patients out of 50 with NE observed from 1984 to 1994 developed one or several intestinal stenosis. Diagnosis of NE was based on usual clinical signs, X-ray pneumatosis (43 to 50) and/or perforation in 16 cases. Among these 16 surgical patients, 12 survived the initial perforation. Among the 34 medical patients, 11 were seen before 1989 and did not have contrast studies before refeeding; 23 seen after 1989 had a contrast enema before. RESULTS: One or several stenosis occurred in four out of 12 surgical patients, four out of 11 medical patients without prospective contrast studies (one of them died from sepsis) and seven out of the 23 of the prospective group. On the whole, 26 stenosis occurred in 15 neonates: ten to the right colon, five to the transverse and 11 to the left colon. One ileal stenosis followed enterostomy. Delay of stenosis development was comparable in the three groups (between 3 weeks and 3 months). Pathologic examination showed similar lesions in the three groups (fibrosis 15, edema nine to 15 and chronic inflammation 12 to 15). CONCLUSION: Among 46 neonates who survived the initial period, 15 developed stenosis, a 30% proportion similar in patients operated on for perforation or in medically-treated patients whose diagnosis was made after occlusion or after contrast enema as well. These results suggest that systematic stenosis detection by contrast enema may avoid complications and permit programmed one-stage surgery.

Umbilical incision for pyloromyotomy.

The umbilical incision is a new approach for the curative procedure of hypertrophic pyloric stenosis in order to avoid the cosmetic impairment from the right upper quadrant incision. Our purpose was to evaluate the morbidity of the two approaches. One hundred and eighteen children operated on through an umbilical incision (UMB) from 1992 to 1994 were retrospectively compared with 121 children who underwent standard incision, in the right upper quadrant (RUQ), from 1989 to 1991. The two groups were homogeneous with regard to age, sex ratio, weight, and prematurity rate. Mean operating times were longer in the UMB group (52 [ +/- 14] minutes versus 38 [+/- 14] minutes, p < 0.001, t test). Morbidity was not significantly different with regard to mucosal perforations, vomiting during the first 24 postoperative hours, wound infections, stenosis relapses, and wound dehiscences. Postoperative hospital stays tend to be shorter in the UMB group as compared to the RUQ group. Thus, despite slightly increased mean operating times, the umbilical incision did not modify the morbidity of pyloromyotomy and left an almost undetectable scar.

[Treatment of ruptures of the posterior urethra in children? The value of the symphyseal approach].

Eight cases of rupture of the posterior urethra were observed in children and treated via a trans-symphyseal approach. Repair was easy in the cases seen rapidly (2 to 10 days), urethral suture was effective and the result was excellent. On the other hand, in cases seen later (6 cases), between 6 months and 5 years, marked fibrous callus had to be resected. Urethral repair was not always possible (only one failure out of 6 late cases). This approach preserves genital functions.

[Value of percutaneous nephrostomy in the management of posterior urethral valves in newborn infants].

OBJECTIVES: This study evaluates the place of percutaneous nephrostomy (PCN) in neonates with posterior urethral valves (PUV). MATERIAL AND METHODS: 11 neonates with PUV, 10 of which were diagnosed antenatally, were treated. PCN drainage was performed in 9 cases, prior to endoscopic resection. Six PCN were bilateral and 3 were unilateral, for the following indications: renal failure in 5 cases, severe infection in 2 cases, evaluation of a dilated kidney in 2 cases. RESULTS: These PCN were left in place for an average of 18 days. Two cases of asymptomatic postoperative bacteriuria were observed. One nephrectomy and one cutaneous ureterostomy followed by reimplantation for megaureter were performed on the diverted kidneys. CONCLUSION: PCN has become the method of upper tract diversion in most cases of neonatal PUV. In addition to the classical indications (severe urinary tract infection, renal failure), it allows perfectly safe resection of valves in the case of upper tract dilatation and assessment of the kidneys.

The value of split renal function in severe neonatal and infant pelviureteric obstruction managed by percutaneous nephrostomy.

A percutaneous nephrostomy (PCN) was inserted as part of the management in 17 newborns and infants with severe pelviureteric junction obstruction between 1981 and 1993. Nephrectomy was performed in eight cases and pyeloplasty in nine cases, successfully in six cases (mean follow-up: 7.7 years). PCN was useful for predicting that no non-functioning kidney on intravenous pyelography (IVP) in this series should have been preserved. Among the kidneys with a high excretion delay on IVP, PCN showed that only those that had a split creatinine clearance of more than 1 ml/min/1.73 m2, or theoretical clearance for age and weight of over 6%, should be preserved.

[Congenital uro-intestinal fistulas].

The congenital uro-enteral fistula are observed essentially in boy and quite exclusively with anorectal malformation. Cloacal anomaly in girl and cloacal exstrophy in both sexes are so exceptional than complex malformations.

Amputation of penis after circumcision--penoplasty using expandable prosthesis.

A two-year-old boy was referred for correction of an amputation of penis following ritual circumcision. The reconstruction involved mobilization of the profound part of corpora cavernosa and coverage by a vascularised flap taken from the hypogastric area through the use of a sub-cutaneous expandable prosthesis. After two years, appearance of the neo-penis is satisfactory considering the initial lesions.

The risk of wound infection after inguinal incision in pediatric outpatient surgery.

To study the risk of wound infection in pediatric outpatients, two series of children operated on with an inguinal incision during a 5.2 year period in the same department, either in day-surgery or in standard hospitalization, are compared. It appears that the frequency of inguinal wound infection is lower for outpatients (1%; 18/1816) than for inpatients (4%; 17/427). This difference is due, on the one hand, to the way day-surgery hospitalization functions and, on the other hand, to the difference of population produced by the criteria for selection for admission in the Day-Surgery Unit.

Histiocytosis X revealed by complex anal fistula.

A very unusual clinical case of histiocytosis X in a young girl with no unusual medical history, is presented. The patient presented with chronic suppuration of the groin and complex anal fistulae and multiple recurrent abscesses, despite surgical treatment (abscess drainage, terminal colostomy). Intestinal and immunologic evaluation were normal. Only histology made the diagnosis. Chemotherapy (vinblastine) resulted in healing and the colostomy was closed.

Expandable prosthesis in right postpneumonectomy syndrome in childhood and adolescence.

Right pneumonectomy can lead to severe respiratory impairment due to stenosis of the left main bronchus. This syndrome is usually treated by inserting a fixed-volume prosthesis but, in children, expandable prostheses have the advantage of being adaptable to growth and permit progressive recentering of the mediastinum. We report 3 such cases, with the results of pulmonary function tests. The patients were aged 11, 17, and 22 years at the time of implantation and had undergone pneumonectomy during childhood for either bronchiectasis or complete pulmonary sequestration. All 3 patients are doing well, with a follow-up of 1 to 3 1/2 years. Pulmonary function tests have shown a substantial improvement in the obstructive syndrome in 2 patients whereas, in the third patient, in whom the contralateral lung was not perfectly healthy, the functional improvement was only moderate.

Choledocho-ureteral anastomosis in the rat. A new experimental model of long-term, total, internal bile diversion.

Choledocho-ureteral anastomosis is a new experimental model of total bile diversion in the rat. The anastomosis is carried out using a polyethylene tutor drain and requires neither an external drain nor restraint of the animal. After 14 days of diversion, bile flow fell by 53% and there were no biological signs of cholestasis. The rats survived for up to 2 months. Choledocho-ureteral anastomosis is a reliable and simple experimental model which can be used to study the effects of prolonged interruption of enterohepatic bile-acid circulation.

[Prenatal screening in utero of urinary abnormalities. Management].

The major benefit of antenatal ultrasonography is to allow early diagnosis of urinary tract malformations before postnatal infection worsens the prognosis. In the majority of cases, there is a unilateral and moderate dilatation requiring a check-up only during the second week of life; treatment subsequently depends on the etiology of the uropathy and the consequences on the kidney. Unilateral severe dilatations and bilateral, but moderate, dilatations must be managed immediately after birth in a pediatric surgical center. In the rare cases of severe bilateral obstructive uropathy, in utero decompression by catheterisation or surgery is now considered to be uselessly invasive, considering that renal dysplasia is already present when the malformation is detected.

[Treatment of idiopathic vesico-ureteral reflux in children].

Vesicoureteral reflux is the principal cause of pyelonephritis in children. Medical treatment is designed to prevent the development of renal parenchymal scars, as these lesions are irreversible and frequently interfere with growth of the kidney. Treatment must therefore be specific and sufficiently prolonged. In infants under the age of 2 years, reflux may resolve in 50% of cases as the ureterovesical junction develops. During this period, treatment consisting of alternating antiseptics should be proposed to prevent the development of pyelonephritis. In all other cases, reflux must be corrected. Two techniques can be proposed at the present time: surgery which gives 98% immediate and permanent good results, using Cohen's technique, and injection of Teflon, which is much less reliable, with risks of distant dissemination, particularly to the brain, and the possibility of developing ureteric stenosis and bladder stones. These problems have led many paediatric urologists to abandon endoscopic treatment.

[Current treatment of bladder exstrophy].

The treatment of vesical exstrophy has greatly improved over the last twenty years. The most important progresses are: closing the bladder before the 72nd hour of life; iliac osteotomy allowing fusion of the pubis when closing the bladder; lengthening of the penis by liberation of the corpora cavernosa; entero-cystoplasty when the reconstructed bladder is too small. Most surgeons practice the same timing for the different operations. Urinary and genital anomalies can be cured at the same time. In relation to urinary problems, about 80% of cases achieve good continence. An urinary diversion, using "Coffey's" technique, must be performed in the presence of incontinence. Concerning genital problems in boys and girls, reconstructive surgery allows restoration of almost normal genital organs. Intercourse seems to be satisfactory in most cases. There is a high sterility rate in men.
