Management of Hirschsprung's disease: Curative surgery before 3 months of age

Curative surgery of Hirschsprungs disease (HD) was performed in 32 infants younger than 3 months of age from January 1, 1977, December 31, 1986. There were 24 males, seven of whom presented with total colonic aganglionosis. Preoperative relief of obstruction was carried out by only enemas in 25 patients (81%), with addition of total parenteral nutrition of 8 to 27 days in case of severe enterocolitis. Colostomy was never performed as a routine procedure. Preoperative morbidity occurred in three cases: one enterocolitis and two sigmoid performations that were successfully treated by colostomy. Weight at operation ranged from 3.3 to 6.0 kg (mean, 4.9 kg). Swensons (25), Duhamels (5), and Soaves procedures (2) were performed. There was no mortality. Follow-up varied from 2 to 10 years. Postoperative morbidity occurred in five patients (one anastomotic leak, two stenosis, one volvulus, and one recurrent enterocolitis). All other patients are considered as definitively cured. Comparison with data in the literature permits one to advocate primary corrective treatment of HD without decompression in infants less than 3 months of age.

Double-lung transplantation in children: A report of 20 cases

In the last 3 1/2 years, we have performed 20 double-lung transplantations in children between 7 and 16 years old (mean age, 13 years). One patient had primitive bronchiolitis obliterans and the other 19, cystic fibrosis. Eight patients were operated on in an emergency situation, 7 of them requiring ventilator support before transplantation. The procedures were en bloc double-lung transplantation in the first 11 patients with separate bronchial anastomoses in 10, and sequential bilateral lung transplantation in the later 9 patients. There were no operative deaths. Two patients died in the hospital on postoperative days 37 and 73, and there were four late deaths, which were due to infection, rejection, and bronchiolitis obliterans. The acceptable incidence of airway complications, the improvement in lung function of survivors, and the acceptable midterm survival make double-lung transplantation an acceptable alternative to heart-lung transplantation in children. However, in very small children, heart-lung transplantation may be preferable because of the size of the airway anastomoses at risk.

Management of Pediatric Laryngotracheal Stenosis

In the past 6 years, 40 children underwent surgery for laryngotracheal stenosis; 32 by the external approach and 8 by endoscopic CO2 laser. Twenty-seven children (67%) were less than 5 years old at the time of treatment and 80% of the stenoses (n = 32) corresponded to an etiology that is secondary to endotracheal intubation and/or tracheotomy. By grading the stenoses according to the amount of narrowing of the lumen, the authors emphasize the interest of conservative treatment (endoscopic for grade I [less than 70%, n = 8], and treatment by external surgical methods for grade II [70% to 90%, n = 13], grade III [90% to 99%, n = 14], and grade IV [total obstruction, n = 5]). At this time, the most commonly used technique is laryngotracheoplasty with costal cartilage interposition. In this series, 88% of the patients were successfully decannulated. As for the treatment of stenosis in infants, the authors describe their recent experience of laryngotracheofissure in 7 patients as an alternative to either tracheotomy in cases of difficult extubation or laryngotracheoplasty when the child is underweight.

Extradural hematomas in infants

This study reports 19 cases of extradural hematomas in infants for their relative frequency in head injury of children, their clinical findings, their particular evolution and the therapeutic problems specific to this age.
