    BACKGROUND: Short bowel syndrome (SBS) is defined as the malabsorptive state that often follows massive resection of the small intestine. Most cases originate in the newborn period and result from congenital anomalies. It is associated with a high morbidity, is potentially lethal and often requires months, sometimes years, in the hospital and home on total parenteral nutrition (TPN). Long-term survival without parenteral nutrition depends upon establishing enteral nutrition and the process of intestinal adaptation through which the remaining small bowel gradually increases its absorptive capacity. The purpose of this article is to perform a descriptive systematic review of the published articles on the effects of TPN on the intestinal immune system investigating whether long-term TPN induces bacterial translocation, decreases secretory immunoglobulin A (S-IgA), impairs intestinal immunity, and changes mucosal architecture in children with SBS. METHODS: The databases of OVID, such as MEDLINE and CINAHL, Cochran Library, and Evidence-Based Medicine were searched for articles published from 1990 to 2001. Search terms were total parenteral nutrition, children, bacterial translocation, small bowel syndrome, short gut syndrome, intestinal immunity, gut permeability, sepsis, hyperglycemia, immunonutrition, glutamine, enteral tube feeding, and systematic reviews. The goal was to include all clinical studies conducted in children directly addressing the effects of TPN on gut immunity. RESULTS: A total of 13 studies were identified. These 13 studies included a total of 414 infants and children between the ages approximately 4 months to 17 years old, and 16 healthy adults as controls; and they varied in design and were conducted in several disciplines. The results were integrated into common themes. Five themes were identified: 1) sepsis, 2) impaired immune functions: In vitro studies, 3) mortality, 4) villous atrophy, 5) duration of dependency on TPN after bowel resection. CONCLUSION: Based on this exhaustive literature review, there is no direct evidence suggesting that TPN promotes bacterial overgrowth, impairs neutrophil functions, inhibits blood's bactericidal effect, causes villous atrophy, or causes to death in human model. The hypothesis relating negative effects of TPN on gut immunity remains attractive, but unproven. Enteral nutrition is cheaper, but no safer than TPN. Based on the current evidence, TPN seems to be safe and a life saving solution

    PURPOSE: The aim of this study was to compare the effects of enteral and total parenteral feeding on septic complications in neonates on extracorporeal membrane oxygenation (ECMO). METHODS: Ninety-six neonates were on ECMO between January 1992 and February 1998. Matching for diagnosis and exclusion of neonates with sepsis before ECMO or undergoing surgery on ECMO left 16 enterally fed neonates (cases) and 35 parenterally fed neonates (controls) for analysis. Septic complications were scored using the criteria of the Society of Critical Care Medicine and the American College of Chest Physicians adapted to children. RESULTS: Both groups were comparable with respect to gestational age, sex, and age at initiation of ECMO. The frequency of septic complications did not differ between cases and controls: no complications, 75% versus 69%; systemic inflammatory response syndrome, 13% versus 6%; bacteremia, 6% versus 14%; sepsis, 6% versus 11%. There were no complications associated with enteral feeding. The ECMO run was significantly longer in the case group (median, 161 v. 111 hours; P =.01) and mortality rate was lower in the case group (0 v. 14%; P =.17). CONCLUSIONS: Enteral nutrition does not affect the risk of sepsis in neonates on ECMO when compared with total parenteral nutrition. Enteral nutrition is well tolerated and not associated with adverse effects

Diseases involving the gastrointestinal tract, such as necrotizing enterocolitis, may affect gut hormone secretion and therefore influence gut functions. Because bowel rest is an important part of the treatment, infants with this disease are especially at risk for an altered gut hormone secretion and thus for compromised gut functions.METHODS In the current study, the gastrointestinal hormone profiles of eight preterm infants with an ileostomy after necrotizing enterocolitis (Bell stages 2 and 3) were evaluated during starvation and reintroduction of enteral nutrition. Basal and postprandial plasma concentrations of gastrin, cholecystokinin, and peptide YY were measured with sensitive and specific radioimmunoassays. The results were compared with those of 11 controls.RESULTS In the patients and the controls, plasma concentrations of all hormones were higher postprandially. The increases in cholecystokinin and peptide YY were significant in the patients. Compared with the controls, all concentrations were higher in the patients, and changes were significant for basal and postprandial cholecystokinin and postprandial peptide YY.CONCLUSIONS Enteral nutrition stimulates the secretion of gastrointestinal hormones, also in premature infants with a diseased distal small bowel and colon, as in necrotizing enterocolitis. The postprandial increase of peptide YY in patients with an ileostomy indicates that enteral substrate in the colon is not necessary for stimulation of peptide YY secretion
