Is prophylactic fundoplication necessary in neurologically impaired children?

BACKGROUND: Previously, concomitant antireflux surgery was performed in all neurologically impaired children undergoing gastrostomy tube placement in our department. This fundoplication procedure, not necessarily performed for symptomatic gastroesophageal reflux, increased the postoperative complications. This practice was changed and fundoplication was offered to only those children who had clear surgical indications for an antireflux procedure on follow-up after a feeding gastrostomy. METHODS: In the period from 1996 to 2007, all children who underwent gastrostomy with fundoplication were compared with those in whom feeding gastrostomy alone was done. The clinical symptoms, investigations and indications for gastrostomy and fundoplication were recorded. The children who underwent gastrostomy were followed up for symptoms of gastroesophageal reflux and the need for subsequent fundoplication was studied. The complications directly related to surgery were also studied and statistically analyzed. RESULTS: A total of 137 children had gastrostomy insertion, 60 of whom underwent fundoplication. Of these 60 children, 45 had concomitant fundoplication and gastrostomy. In the patients who had gastrostomy alone, a subsequent fundoplication procedure was required only in 17.1% (14 of 82). The complication rate as well as the severity of complications directly related to surgery was found to be higher in the gastrostomy+fundoplication group (18 of 60) compared with those who had only gastrostomy (12 of 82) (p=0.036). CONCLUSION: Prophylactic fundoplication may not be necessary in neurologically impaired children undergoing gastrostomy for feeding purposes. It increases the postoperative morbidity compared to gastrostomy alone in this group of children. It should be offered selectively to children continuing to have reflux-related complications after gastrostomy. The technical difficulties with a pre-existing gastrostomy can be overcome in the hands of experienced laparoscopic surgeons.

Fryns syndrome: a surviving case with associated Hirschsprung's disease and hemidiaphragmatic agenesis.

Fryns syndrome is a rare autosomal recessive disorder of multiple congenital abnormalities. Major diagnostic criteria include congenital diaphragmatic hernia, distal limb and nail hypoplasia and abnormal facies. More than 70 cases have been reported since the first report in 1979, 86% of which have been associated with an early lethal outcome. We report the case of a survivor who also has associated Hirschsprung's disease. On review of previously reported cases, defects of neuronal migration may be more common than previously recognized. The diaphragmatic hernia was repaired in two stages with a silastic patch followed by a reversed latissimus dorsi muscle flap.

Reconstruction of congenital agenesis of hemidiaphragm by combined reverse latissimus dorsi and serratus anterior muscle flaps.

BACKGROUND/PURPOSE: Diaphragmatic agenesis (DA) is a distinct clinical entity with poorer survival rate compared with patients with posterolateral diaphragmatic hernia. The large defect in DA is repaired frequently with a synthetic patch in the neonatal period. Well-known, long-term complications include recurrent hernia caused by patch dislodgement, chest wall deformation caused by noncompliant patch, and deteriorating pulmonary function. A reverse latissimus dorsi flap (RLD) allows continued growth of the reconstructed diaphragm with an intact pleuro peritoneal separation. When combined with neuroanastomosis of the phrenic and thoracodorsal nerves it has the potential to function as a native diaphragm. Incorporation of Serratus anterior (SA) muscle enables reconstruction of larger defects. METHODS: Two cases of DA are presented. In each case the primary SILASTIC(R) (Dow Corning, Midland, MI) patch repair failed and was replaced successfully with a RLD flap reconstruction with or without incorporation of SA and neuroanastomosis. RESULTS: Both patients recovered from surgery with minimal morbidity. The reconstructed diaphragm is intact at long-term follow-up. There is marked improvement of growth of the infants, respiratory difficulties, and chest wall deformity. CONCLUSIONS: This technique is recommended in DA when the synthetic patch fails.

Intrascrotal CGRP 8-37 causes a delay in testicular descent in mice.

The genitofemoral nerve is a key factor in the inguinoscrotal descent of the testis. The effect of androgens may be mediated via the central nervous system, which in turn secretes the neurotransmitter calcitonin gene-related peptide (CGRP) at the genitofemoral nerve endings, to cause testicular descent. The effect of endogenous CGRP was examined by weekly injections of a vehicle with or without synthetic antagonist (CGRP 8-37) into the developing scrotum of neonatal mice. The descent of the testis was delayed in the experimental group compared with the control group. At 2 weeks of age 43% of controls had descended testes compared with 0% of experimental animals. At 3 weeks of age 17% of experimentals still had undescended testes, whereas all testes were descended in controls. At 4 weeks 3 testes remained undescended in the experimental group. It is concluded that the CGRP antagonist can retard testicular descent. This result is consistent with the hypothesis that CGRP is an important intermediary in testicular descent.
