Follow-up studies in 50 totally colectomised children.

We report on 50 totally colectomised children, most of whom suffered from Hirschsprung's disease. Of the 50, one child died postoperatively of enteritis. On an average, the children were re-examined 5 1/2 years after the colectomy. The findings were as follows: With the exception of four, the size and weight of the patients were within the norm; 20 passed frequent stools of pulpy consistency; 16 suffered from disturbances of continence; 14 developed severe, partially recurrent enteritis. We did not find any advantage of a single method of operation, e.g. Martin's operation.

Anorectal anomalies--international classification.

80 patients with anorectal anomalies were admitted to the Paediatric Surgical Service of the National Hospital of Norway during the five year period 1970--74. The anomalies were classified according to the International Classification which was found to be of obvious value in comparing material and results. Intermediate and high deformities were generally treated with an initial colostomy and a subsequent sacroperineal pullthrough operation. The low anomalies were generally treated with an anoplasty in two procedures. Patients with poor functional results and incontinence can be improved with free muscle transplantation.

Diagnosis, Differential

Gastroschisis and omphalocele.

A series of 100 patients with gastroschisis and omphalocele is presented. It is emphasized that gastroschisis generally has a strikingly homogeneous clinical presentation, while the omphalocele has a more heterogeneous clinical presentation, varying from the smallest to the largest, nearly incorrectable type. The main problem in the two groups is the problem of the closure of the defect. In gastroschisis there are, in addition, two problems related to the length of the intestinal tract and the tendency to peritonitis and septicaemia. In omphalocele, however, the major problem is the associated anomalies. The experience from the present material indicates that greater efforts must be used in the future in trying to avoid hypothermia, both during transportation and during operation. Furthermore, greater efforts must be made in closing the abdominal wall defect primarily in both groups of patients. More liberal use of respirator and total parenteral nutrition, mainly by peripheral veins, has obviously contributed to the improvement in our results from 1 60% mortality rate in the first nine-year period to a 37% mortality rate in the last nine-year period in the omphalocele group. Our best results have been obtained during the last 3 years with 2 deaths in the last 12 patients who all were treated by primary closure. In the gastroschisis group a survival rate of 69% in the whole series and of 74% in those who were primarily completely closed must be looked upon as progress in the light of earlier reports of survival rates of 36% to 43%.

Early reconstruction of wide ureter in children.

Fifty children with 66 megaureters have been treated with complete surgical reconstruction and reimplantation of the ureter. The procedure was done unilaterally in 34 and bilaterally in 16 patients. Fourteen of the bilateral cases were corrected in one procedure. The results in the reported series seem to justify the conclusion that early reconstruction forms a ureter which is neither wide, nor elongated, nor tortuous and thus able to transport urine.

Congenital diaphragmatic hernia: the hidden mortality.

From 1969 to 1975, 33 cases of congenital diaphragmatic hernia (CDH) were treated at the National Hospital of Norway with a "visible" or operative mortality of 30%. At least 37 additional infants with CDH who died soon after birth and did not come to the attention of a major referral center were identified retrospectively from a comprehensive survey of neonatal deaths. CDH occurred at least once in every 5455 live births and the "true" mortality was 66%. More than half of the infants born with CDH during this 6-yr period died before they could be treated, contributing to a substantial "hidden" mortality.

Surgical treatment of primary liver carcinoma.

Forty-five patients with primary liver carcinoma were treated between 1960 and 1975. Sixteen patients were less than 15 years of age. All patients underwent diagnostic laparotomy, while liver resection was performed in 16 (36%). Resectability was higher in children than in adults. Left lobectomy was performed in 8 patients, right lobectomy in 3, and an extended right lobectomy in 5 patients. One patient died postoperatively, i.e. mortality was 6%. Of the surviving 15 patients 4 died from metastatic tumor within 18 months after surgery. Patient survival at 2 years was 73%. The present material favors radical surgery of primary liver carcinoma whenever possible.
