From 1976 to 1995, 23 children, 4 boys and 19 girls, were treated at our department for sacrococcygeal teratomas (SCT). Their records were analyzed retrospectively, considering age at operation, histopathology, recurrences, and long-term evolution. One died on the 1st day of life following tumor rupture with hemorrhagic shock without surgical intervention. All others were operated upon at a mean age of 4.2 days for those 19 (= 82%) who were diagnosed in the neonatal period and whose histology proved benign. In the remaining 3 children, in whom tumor manifestation did not occur before 11 months, 13 months, and 10 years of age, respectively, histopathologic evaluation revealed 2 carcinomas and 1 yolk-sac tumor, and all 3 recurred. Overall, 5 patients died, the 1 mentioned above, 1 due to volvulus after laparotomy, and 1 from multiple associated congenital malformations. Two deaths were related to malignancy, whereby only 1 was a malignant teratoma diagnosed at the original operation. Eight children had recurrences, 2 were benign and 6 malignant, with 3 of the latter having been graded benign on histology of the primary tumor. Of the 18 surviving patients, 17 (93.5%) returned for clinical review following a standardized protocol. The average interval from the primary surgery was 12.3 years (range 3.5-22 years). Four had malignant tumors with a recurrence-free period of from 9 to 14 years; 5 (29.4%) had urinary or anorectal functional impairment. One child with a patulous anus presented with fecal soiling. Two reported nocturnal enuresis, 1 associated with perineal anesthesia. One had a neurogenic bladder with overflow voiding and bilateral third-degree vesicoureteral reflux. Second-degree reflux was found in the last patient. We conclude that follow-up after surgery for SCT should not only search for tumor recurrence but include the diagnosis and treatment of possible secondary urinary and/or fecal incontinence.

Sonography was compared to pH-metry and/or oesophagomanometry to evaluate the accuracy of sonography in the early diagnosis of gastro-oesophageal reflux. Thirty children with a mean age of 72 days (21-252 days) were studied. The results showed that specificity of sonographic diagnosis was 87.5% and sensitivity was 100% (with P less than 0.001). Sonography also proved helpful in providing both functional and morphological data in addition to pH-metric results. This study therefore suggests that sonography is useful as the first approach in the diagnosis of vomiting babies as it is non-invasive and provides sufficient diagnostic accuracy.

During a 16-year period, 60 neonates with gastroschisis were treated at the Department of Pediatric Surgery in Graz; 6 died and 54 (90%) survived. A questionnaire was sent to 45 patients, who were called for a medical examination; 31 patients (69%) came to follow-up, 26 of whom reported minor abdominal problems that could be related to gastroesophageal reflux (GER). Fifteen agreed to 24-h esophageal pH monitoring and/or upper gastrointestinal series; in 7 pathological GER could be demonstrated. Manometric studies in 6 patients revealed a motility disorder of the esophagus. Only 4 children were concerned by a disfiguring scar or the absence of a navel. Heigtt and weight were within normal limits and the children had developed normally.

In young patients, constipation related to IND B can be treated successfully by conservative treatment regimens, including diet, laxatives, and prokinetic drugs.

Mobilization of the anterior urethra for correction of distal hypospadias with or without chordee is highly successful, less extensive, and provides an excellent cosmetic and functional result with a minimal risk of complication. Uroflowmetry is a noninvasive, objective diagnostic tool for evaluating the functional results of hypospadias repair.
