Associated urologic anomalies in low imperforate anus are capable of causing significant morbidity: a 15-year experience.
OBJECTIVES: To determine the incidence and morbidity caused by urologic anomalies in patients with low imperforate anus. METHODS: The case records and imaging studies of 95 patients who underwent surgery for low imperforate anus over a 15-year period were retrospectively reviewed. Follow-up ranged from 2 to 18 years (mean 5.4). RESULTS: Genitourinary abnormalities were seen in 29 patients (31%), whereas 10 (11%) had lumbosacral abnormalities. A micturating cystourethrogram was performed in 48 patients, 18 of whom were shown to have vesicoureteric reflux and 2 of whom required surgical correction. Three additional patients required bilateral ureteric reimplantation: 2 had megaureters whereas 1 had bilateral ectopic ureters. Four patients had evidence of chronic renal failure; these included 1 patient with reflux nephropathy, 2 with bilateral dysplastic kidneys, and 1 with neurogenic bladder. The patient with reflux nephropathy underwent renal transplantation at the age of 18 years. Two patients had proximal hypospadias and 4 had undescended testes. A neurogenic bladder was documented in 5 children, 4 of whom had lumbosacral abnormalities. One of these had a spinal lipoma and required excision of the lipoma and untethering of the spinal cord. CONCLUSIONS: We conclude that 30% of patients with low imperforate anus would have associated urologic anomalies, several of which are capable of causing significant morbidity. Thus, all patients with imperforate anus, whether high or low, need to be screened for associated urologic anomalies.

Operative trauma to the genitourinary tract in the treatment of anorectal malformations: 15 years' experience.
OBJECTIVES: To determine the incidence of urologic trauma during surgical correction of anorectal malformations (ARM). METHODS: The records of 228 children with ARM were retrospectively reviewed. RESULTS: Operative trauma to the genitourinary tract was seen in 12 patients, all male. Of 133 patients with a high ARM, 92 underwent an abdominoperineal pull-through and 41 underwent a posterior sagittal anorectoplasty (PSARP); the incidence of urologic trauma was 12% and 0%, respectively. In the subgroup of male infants with a high ARM (99 patients), the incidence of genitourinary trauma was 11%; in those with a low anomaly, the incidence was 1 of 43 (2%). There were 3 urethral tears, 4 urethral strictures, 5 urethral diverticula, 2 vas deferens injuries, and 1 ureteric injury. Nine of the 12 patients do not have any long-term sequelae resulting from the injuries; however, 2 are now infertile and 1 has urinary incontinence. Four patients are additionally compromised because of an absent or nonfunctioning kidney on one side. CONCLUSIONS: In children with ARM, those undergoing a conventional pull-through repair are more likely to have a genitourinary injury than those undergoing the PSARP, and boys with high ARM are at greatest risk.

Management of the isolated congenital tracheo-oesophageal fistula.
Over a ten-year period sixteen infants with isolated congenital tracheo-oesophageal fistulas (TOF) were treated. All infants were symptomatic from birth although the diagnosis was only established in the neonatal period in eleven cases. Tube oesophagography was the diagnostic investigation of choice. Bronchoscopic cannulation of the fistula greatly assisted division, which was achieved through a cervical incision in all cases. There were two early recurrent fistulas both of which closed spontaneously. Persistent oesophageal symptoms were common. Seven of the patients (43%) experienced dysphagia, three of whom developed oesophageal strictures requiring repeated dilation.

Management of alimentary tract duplication in children.
Duplication of the alimentary tract is rare but potentially dangerous. Five of 72 children with alimentary tract duplication treated between 1973 and 1992 died from postoperative complications; a further ten required more than one operation. Ileal duplications were the commonest, occurring in 16 patients (22 per cent). Thoracoabdominal duplications were the most complicated and responsible for much of the overall morbidity and mortality. Surgical complications were related to the size and location of the duplication, communication with the gastrointestinal tract or vertebral canal, presence of heterotopic gastric mucosa and involvement of mesenteric vessels. Complete excision of the duplication should be possible in most cases.

Scattered radiation in a neonatal surgical unit.
We studied the doses of "scattered" received by neonates in a Neonatal Surgical Unit by placing thermoluminescent dosemeters in various positions expect the direct beam. Doses of "scattered" radiation received by neonates as a results of exposure of their neighbours to X-ray examinations were found to be negligible. Sick neonates need not be moved from their neighbours undergoing exposure to X-rays.

Meconium ileus due to extensive intestinal aganglionosis.
Seven full-term infants with aganglionosis extending into the small bowel presented with clinical, radiological, and operative features of meconium ileus. Misdiagnosis resulted in inappropriate treatment. The correct diagnosis was eventually established by rectal suction biopsy, mostly after either recurrent intestinal obstruction or stomal dysfunction, and after cystic fibrosis had been excluded. For two patients, the results of rectal suction biopsies were initially misleading. Two infants died. Extensive intestinal aganglionosis should be considered a rare possibility in all infants with meconium ileus. In such cases, histological examination of the appendix may avoid this potential pitfall.

Oesophageal atresia: at-risk groups for the 1990s.
The authors analyzed the outcome for 357 infants with oesophageal atresia and 15 with H-type tracheoesophageal fistula treated from 1980 through 1992. Survival according to Waterston risk categories was 99% for group A, 95% for group B, and 71% for group C. Presently, with optimal management, virtually all infants in groups A and B should survive. When examining the risk factors in the infants who died, two criteria were found to be important predictors of outcome: birth weight of less than 1,500 g and the presence of major congenital cardiac disease. A new classification for predicting outcome in oesophageal atresia is proposed: group I: birth weight > or = 1,500 g, without major cardiac disease, survival 97% (283 of 293); group II: birth weight < 1,500 g, or major cardiac disease, survival 59% (41 of 70); and group III: birth weight < 1,500 g, and major cardiac disease, survival 22% (2 of 9).

Mediastinal teratomas: review of 15 pediatric cases.
One hundred fifty-three children with a teratoma presented to one hospital between 1970 and March 1992. The clinical and pathological features of 15 patients with mediastinal teratomas are reviewed; six were newborn and nine aged from infancy to 13 years. Thirteen patients including the six newborns presented with respiratory distress and all 15 patients had a mass on chest radiograph. A definite diagnosis of teratoma was not made preoperatively in any of these patients. At operation, a median sternotomy was used to approach seven anterior tumors and a lateral thoracotomy performed in the other eight patients. Histologically two were mature, 10 had immature elements, and three were malignant teratomas. The patients with malignant tumors were all over 12 years of age and died within 6 months of treatment. All six neonates had immature teratomas. Raised serum alpha-fetoprotein levels provided useful markers in two patients with recurrent tumors. Three conclusions can be drawn: (1) mediastinal teratomas are rare in children and frequently are not diagnosed before operation; (2) in newborns these tumors may be immature and present with respiratory distress; and (3) a median sternotomy gives excellent exposure for anterior mediastinal tumors.

Recurrent necrotizing enterocolitis.
In the decade 1981 to 1991, 16 infants developed recurrent necrotizing enterocolitis (NEC). They comprised 12 (6%) of 196 neonates referred for further management of NEC and four others referred with major congenital anomalies. Their median gestational age was 32 weeks (range, 27 to 40), median birth weight was 1,260 g (range, 790 to 3,230), and the sex distribution was equal. Recurrent NEC occurred after a median interval of 37 days (range, 11 to 163) from the onset of the initial episode. All but one of the 16 infants were either premature (n = 10) or mature with major congenital anomalies (n = 5). Nine patients had previously undergone surgery for NEC. Medical treatment was successful in 11 patients with recurrent NEC. Two infants died, both of liver failure related to parenteral nutrition; one of whom had suffered four separate episodes of NEC and was found to have a superior mesenteric artery occlusion. There was no consistent association between recurrent NEC and the type or timing of enteral feeds or the anatomical site or method of management of the original attack. The mortality of 12.5% was similar to that for primary NEC.

Aortopexy for tracheomalacia in oesophageal anomalies.
Forty-eight patients with repaired congenital oesophageal anomaly underwent aortopexy for significant tracheomalacia between 1980 and 1990. Indications for aortopexy included recurrent apnoea/cyanosis in 31, near fatal episodes in 16, recurrent respiratory distress and infection in 20 and worsening stridor in 15. Gastro-oesophageal reflux was noted in 30 patients, recurrent fistula in 6 and oesophageal stricture in 14. Aortopexy cured near fatal episodes in all patients and resulted in improvement of airway obstruction in 95%. The procedure failed in 2 patients due to unrecognised bronchomalacia and phrenic nerve palsy respectively. Aortopexy is the primary procedure of choice for significant tracheomalacia when associated with near fatal episodes and significant airway obstruction.

Operation for gastro-oesophageal reflux associated with severe mental retardation.
One hundred and seventy six children with severe mental retardation underwent a fundoplication for considerable gastro-oesophageal reflux. There were six 'early' (3%) deaths and five 'late' deaths. Major complications developed in 17 (10%) children whereas 86 (49%) had 'minor' complications. A revision operation was required in 27 patients. Overall 142 (81%) children achieved a good result. In spite of the high complication rate and the need for a secondary operation in 15% of the patients, the quality of life for these children and their parents and carers is greatly improved by antireflux surgery.

Childhood deaths from intussusception in England and Wales, 1984-9.
OBJECTIVE: To assess the incidence of potentially avoidable factors contributing to death of children with intussusception. DESIGN: Review of children who died with intussusception in England and Wales between 1984 and 1989 from data of the Office of Population Censuses and Surveys, case notes, coroners' records, and necropsy reports. MAIN OUTCOME MEASURES: Unambiguous objective criteria such as failure to diagnose intussusception within 24 hours of admission. RESULTS: 33 children died of acute intussusception in England and Wales between 1984 and 1989 compared with 67 in the previous six years. Their median age was 7 months (range 2 months to 12 years), and two thirds were boys. Half of the deaths occurred at home or soon after arrival at hospital but 15 patients had surgery. Potentially avoidable factors contributing to death were identified in 20 (61%) children, all but three of whom had ileocolic intussusception. These factors were excessive delay in diagnosis, inadequate intravenous fluid and antibiotic therapy, delay in recognising recurrent or residual intussusception after hydrostatic reduction, and surgical complications. Of the 13 patients in whom no avoidable factors were identified, there were nine of 11 children with isolated small bowel intussusception, who tended to have atypical presentations. CONCLUSION: Although the mortality from intussusception has declined, there remains ample opportunity for improved management.

Delayed surgery for congenital diaphragmatic hernia.
Between January 1987 and December 1990, 67 neonates were treated for congenital diaphragmatic hernia, symptomatic within 6 h of birth. The mortality rate was 33 per cent. Preoperative stabilization was achieved in 47 patients, all of whom survived initial treatment, although two died later. Stabilization could not be achieved in 20 neonates, all of whom died within 3 days of birth, 18 without undergoing operation and two after early repair. Intensive resuscitation with controlled, delayed operation for congenital diaphragmatic hernia gives long-term results similar to those of urgent operative repair. This approach avoids operation in the majority of those who subsequently die.

Double duodenal atresia/stenosis: a report of four cases.
Four neonates with double duodenal atresia/stenosis are described. Preoperative plain radiographs in two patients demonstrated atypical appearances suggestive of complex pathology. Cystic dilatation of the second part of the duodenum was observed at laparotomy in two patients and in one of these the "cyst" was palpable preoperatively, causing diagnostic confusion. All four patients underwent successful surgery but one infant with Down's syndrome subsequently died of congenital heart disease.

Pancreatic ascites presenting in infancy, with review of the literature.
We report a 4-month-old boy with massive ascites in whom a diagnosis of pancreatitis was made on a raised ascitic amylase level after two inconclusive laparotomies. He developed a pseudocyst which was managed with repeated percutaneous needle aspirations, nutrition being maintained intravenously. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a congenital intra-pancreatic cyst. He thrived after operation drainage for recurrent pseudocyst, but repeat ERCP shows that the cyst in the head of the pancreas remains. Pancreatic ascites is rare in children and diagnosis is frequently delayed. A third of reported cases in childhood present in the first year of life. A search for the underlying cause should include an ERCP to demonstrate abnormalities of the pancreaticobiliary ducts.
