[Umbilical hernia in children].

INTRODUCTION: Umbilical hernia is a common condition in the pediatric population. EMBRYOLOGY: Umbilical hernia is a consequence of incomplete closure or weakness at the umbilical ring, where protrusion of intraabdominal contents may occur. ANATOMY: Fascia posterior to the canal is thinner, creating an area of weakness. Congenital or direct hernia occurs in this area, while herniation in the umbilical canal leads to indirect or acquired hernia. INCIDENCE: The incidence of umbilical hernia is 1.9% to 18.5% in white population. CLINICAL MANIFESTATIONS: The great majority of pediatric umbilical hernias are asymptomatic. Incarceration and strangulation are uncommon. Rupture of umbilical hernia with resultant evisceration is extremely rare. Umbilical hernia may also be the source of intermittent umbilical or abdominal pain. TREATMENT: Treatment options for umbilical hernias range from simple observation to surgical repair. The great majority close spontaneously and observation with periodic follow-up is appropriate in most cases. There are no available data to suggest that strapping improves or accelerates closure. Operation would be recommended for defects greater than 1 cm, by the age 3 to 4. Persistence or enlargement of fascial defect during the period of observation are reasons to consider repair, whatever the age. COMPLICATIONS: Complications of operative repair of umbilical hernias include those related to anesthesia and local wound infections. CONCLUSION: Umbilical hernia is a common condition among infants and children. In the great majority of cases, the natural history is one of eventual closure without treatment. If spontaneous closure does not occur until the age of 3-4 years, operative correction is recommended.

[Clinical evaluation of fecal continence after posterior sagittal anorectoplasty in anorectal abnormalities].

INTRODUCTION: Posterior sagittal anorectoplasty (PSARP) was introduced in 1982, by Pena and de Vries, as a new surgical procedure for patients with anorectal malformations. It was supposed to provide better chance for normal fecal continence. MATERIAL AND METHODS: Between 1991 and 2000, 50 patients with anorectal abnormalities underwent PSARP. In 43 patients PSARP was primary operation and in 7 it was a secondary procedure. At the time of study patients were not younger than 3, and not older than 13 years. Patients and their parents were interviewed, and fecal continence was graded as follows: voluntary bowel contractions, soiling less than once a week, soiling more than once a week, daily soiling and constipation. RESULTS: Amongst patients who underwent primary surgical correction, 74% had voluntary bowel contractions. Babies with perineal fistula, rectal atresia and stenosis presented with best results in term of voluntary bowel contractions (100%), as with vestibular fistula, ten of eleven patients. Only 18% of patients (atresia without fistula, vestibular fistula and bulbourethral fistula) had soiling. Patients with perineal fistula and rectal atresia and stenosis 40% were totally continent (voluntary bowel movements without soiling). The most frequent sequel was constipation, which appeared in 48%, without coincidence with frequency of soiling. The problem of constipation was surprisingly more frequent in patients with expected better prognosis in fecal continence. CONCLUSION: Although PSARP offers a good esthetic result, only two third of patients have voluntary bowel movements and in about half there exists a problem with constipation, with necessary further treatment.

Associated congenital anomalies: vestibular fistula, duodenal atresia and obstructive refluxing megaureter.

Congenital gastrointestinal anomalies include spectrum of malformations, simple ones as well as complex, which are associated with anomalies of other organs and systems of organs. Most infants (50-60%) with imperlbrate anus also have genitourinary, cardiovascular, gastrointestinal and vertebral anomalies. This case report is of a female newborn with prenatally diagnosed duodenal atresia and right hydronephrosis. Clinical investigation revealed an imperforate anus with vestibular fistula. A plain abdominal X-ray showed a "double-bubble" sign, characteristic for duodenal atresia. Intraluminal membrane was excised and sigmoid colostomy was performed in general anesthesia on the first day of life. Ultrasound and intravenous pyelography confirmed a hydronephrotic right kidney and obstructive megaureter after Pena. In the fifth month of life, the ureter was tapered and reimplanted. Six months later, posterior sagittal anorectoplasty was performed. In the seventeenth month of life the colostomy was closed This child attained normal growth and development, normal bowel control, fecal continence without soiling, obstipation and urinary infections.

[Constipation--a common problem in childhood].

INTRODUCTION: Constipation in children is defined as the infrequent and difficult passage of hard stool, not necessarily associated with in-frequent stools. All healthy newborns have their first stool within the first 24 to 48 hours after birth. Intestinal transit time increases with age, therapy decreasing the frequency of stooling. ANATOMY AND PHYSIOLOGY OF ANUS AND RECTUM: Acquisition of fecal continence requires: normal internal and external anal sphincters, puborectal muscle as well as intact sensory input from both the rectal vault and anal canal. ETIOLOGY AND DIFFERENTIAL DIAGNOSIS: During the first year of life, failure to have bowel movement every other day warrants evaluation. During infancy, constipation is usually due to dietary manipulations, malnutrition or some other functional abnormalities. Anatomic causes are found only in 5% of patients. DIAGNOSIS AND THERAPY: Diagnosis relies on history and physical examination. Digital rectal examination usually reveals a shorter anal canal with decreased sphincter tone. The rectal ampulla is dilated and filled with stool. Anorectal manometry is helpful in differentiating functional constipation from aganglionosis or other neurologic problems. Treatment varies depending on the underlying cause. Bowel retraining, aimed at establishing regular daily bowel movement, is of utmost importance in children. The response to treatment is usually dramatic. CONCLUSION: Constipation in children causes anxiety in the family and successful treatment requires persistent reassurance and repeted reevaluation.

Esophageal atresia and situs inversus--an unusual association of abnormalities--a case report.

We present a case report of a neonate with esophageal atresia and tracheoesophageal fistula. In the 31st week of gestation, maternal polyhydramnions was observed by prenatal ultrasonography. Postnatal insertion of an orogastric tube into the stomach was unsuccessful. On auscultation, the apex of the heart was heard at the right side of the thorax, while the liver was palpable 1 cm below the left rib cage. Esophageal atresia with tracheoesphageal fistula and situs inversus of the thoracic and abdominal organs was diagnosed During the first day of life, left transpleural thoracotomy was performed. The fistula was closed and esophageal anastomosis performed. One year after the operation the child had no difficulties when eating solid and liquid foods. More than 50% of infants with esophageal atresia have associated anomalies and the esophagogram showed good passage of contrast with anastomotic stricture. This was the first report of esophageal atresia with tracheoesophageal fistula repair in a patient with situs inversus treated in our Clinic.

[Clinical analysis of congenital abdominal wall defects--omphalocele and gastroschisis].

INTRODUCTION: This is a retrospective analysis of therapeutic approaches and treatment outcomes of congenital abdominal wall defects (omphalocele and gastroschisis) in a five year period. The aim of this study was to identify factors which can affect the prognosis of future therapeutic procedures. MATERIAL AND METHODS: We evaluated 13 children, 7 with omphalocele (2 female/5 male; mean birth weight of 2862 g; mean gestational age of 37 weeks), and 6 patients with gastroschisis (2 female/4 male; mean birth weight of 2640 g; mean gestational age of 36/2 weeks). All patients were treated at the Clinic of Pediatric Surgery from 1999 to 2003. RESULTS: In this study, thirteen cases of congenital abdominal wall defects (omphalocele and gastroschisis) were retrospectively investigated. All patients underwent prenatal ultrasound. Omphalocele was prenatally detected in 42.8% of fetuses, and gastroschisis in 16.7%. Coexisting anomalies were present in 57.1% of patients with omphalocele and in 16.7% of newborns with gastroschisis. Three patients with omphalocele were treated operatively, and four only conservatively. The abdominal wall of patients with gastroschisis was primarily closed in three patients. Two patients required a staged abdominal wall closure. One patient with gastroschisis and intestinal atresia underwent primary closure after partial intestinal resection and enterostomy. Based on these responses, a management protocol (algorithm) was recommended. The most common postoperative complication, in 7 cases of omphalocele, was mechanical ileus (n = 1), whereas among patients with gastroschisis the commonest were mechanical ileus (n = 1) and intestinal perforation (n = 1). The mortality of patients with omphalocele was 52% and with gastroschisis 66.7%. CONCLUSION: A strategy designed to optimize antenatal and neonatal factors is expected to increase the survival rate of patients with abdominal wall defects.
