Failure of enema reduction for ileocolic intussusception at a referring hospital does not preclude repeat attempts at a children's hospital.

Background: Some children with intussusception undergo attempted enema reduction at a hospital without pediatric radiology expertise and are transferred to a children's hospital (CH) if this is unsuccessful. We sought to determine whether a failed reduction (FR) at a referring hospital predicted failure of repeated attempts by a pediatric radiologist at a CH.

Methods: A retrospective review of all children with ileocolic intussusception admitted to a large CH over 9 years was performed.

Pledgeted mattress sutures reduce recurrent reflux after laparoscopic Nissen fundoplication.

Introduction: In response to a perceived increase in the incidence of recurrent reflux after adopting the laparoscopic Nissen fundoplication, we adjusted our technique to include the use of pledgeted, horizontal mattress sutures for crural closure and wrap construction.

Methods: We assessed the impact of this technical modification in children who underwent laparoscopic fundoplication between 1997 and 2007 at a large children's hospital. The medical history, indications, technical details, and outcomes were reviewed.

Stapled intestinal anastomoses in infants.

Background: We reviewed our experience with stapled intestinal anastomoses in infants younger than 1 year and compared operative data and outcome to that of infants who underwent hand-sewn anastomoses.

Methods: Infants younger than 1 year who underwent an intestinal anastomosis over an 8-year period were identified. Stapled anastomoses were constructed in a side-to-side fashion using standard or endoscopic linear cutters.

Abdominal involvement in pediatric heart and lung transplant recipients with posttransplant lymphoproliferative disease increases the risk of mortality.

Background: Posttransplant lymphoproliferative disease (PTLD) is a serious complication in transplant recipients. Abdominal PTLD has been reported, but the prognosis remains undefined. The purpose of this study was to identify the incidence, predisposing factors, and outcome of abdominal PTLD in pediatric cardiothoracic transplant patients.

Induction of fibroblast growth factor 10 (FGF10) in the ileal crypt epithelium after massive small bowel resection suggests a role for FGF10 in gut adaptation.

We have previously reported that fibroblast growth factor 10 (FGF10) is crucial for the survival and proliferation of progenitor cells during embryonic gastrointestinal development. We sought to characterize the potential role of FGF10 signaling in the adaptive response following small bowel resection. Adult wild-type and Fgf10(LacZ) mice underwent 50% small bowel resection (SBR) or sham operation.

Primary gastric tumors of infancy and childhood: 54-year experience at a single institution.

Background/purpose: Primary gastric tumors are rare in infancy and childhood. Because of the infrequent occurrence of these tumors, the clinician may be unfamiliar with optimal management strategies. We review our experience over the past 54 years and the current literature.

Fibroblast growth factor 10 is required for survival and proliferation but not differentiation of intestinal epithelial progenitor cells during murine colon development.

Epithelial-mesenchymal interactions that govern the development of the colon from the primitive gastrointestinal tract are still unclear. In this study, we determine the temporal-spatial expression pattern of Fibroblast growth factor 10 (Fgf10), a key developmental gene, in the colon at different developmental stages. We found that Fgf10 is expressed in the mesenchyme of the distal colon, while its main receptor Fgfr2-IIIb is expressed throughout the entire intestinal epithelium.

The fibroblast growth factor pathway serves a regulatory role in proliferation and apoptosis in the pathogenesis of intestinal atresia.

Background/purpose: Intestinal atresia occurs in 1:5000 live births and is a neonatal challenge. Fibroblast growth factor receptor 2b (Fgfr2b) is a critical developmental regulator of proliferation and apoptosis in multiple organ systems including the gastrointestinal tract (GIT). Fgfr2b invalidation results in an autosomal recessive intestinal atresia phenotype.
