Objective To assess the outcome of the various methods used in creating continent catheterizable conduits.
Patients and methods The case notes were reviewed from 89 patients who underwent the formation of 112 continent catheterizable conduits.
Results Sixty‐five conduits were Mitrofanoff and 47 were antegrade colonic enema (ACE); 21 patients had both. At a mean follow‐up of 34 months, 95 (85%) conduits were still in use. There was no difference in complications between the Mitrofanoff and ACE conduits; 109 (97%) conduits were continent and stomal stenosis occurred 35 (31%). There was no significant difference relating to the conduit used, the reservoir, the stoma type or the stoma site. Only 39% of patients required no revisional surgery.
Conclusion Although urinary and fecal continence can be achieved in most patients there is a high burden of complications and revisional surgery. All patients should be counselled accordingly.
Sepsis is a major complication of total parenteral nutrition (TPN) in children. Gut mucosal atrophy (GMA) and bacterial translocation (BT) occur in patients receiving TPN, and the translocated enteric organisms may cause central venous catheter (CVC) infection. Epidermal growth factor (EGF) has a trophic effect on the gut mucosa and may reduce BT, thereby reducing catheter infection. Using a rat TPN model, the relationship between GMA, BT, and catheter sepsis was examined and the effect on these of intravenous EGF was studied. There were four experimental groups. Group 1 had no CVC, Groups 2, 3, and 4 had a continuous central venous infusion as follows: group 2, saline; group 3, TPN; group 4, TPN with EGF. Groups 1 and 2 had free access to chow, groups 3 and 4 had no enteral feeds. After killing at 1 week, blood, tissue, and catheter specimens were cultured and mucosal morphology analysed. BT was defined as the presence of the same organism in cultures from the gut lumen and mesenteric lymph nodes (MLN). TPN only (group 3) resulted in GMA and BT, and 5 of 12 animals with BT had the same gut bacteria in blood and/or catheter cultures. The addition of EGF to the TPN significantly reduced GMA, BT to the MLN, and blood and/or catheter infections (P = <0.05). In animals carrying enterococci, there was a significant reduction in translocation of enterococci (group 3: 8/14; group 4: 0/11; P<0.05) and catheter infection by enterococci was prevented (group 3: 3/14; group 4: 0/11). EGF thus reduced GMA, BT, and blood and/or catheter infection when given IV to rats receiving TPN. Enterococcal translocation and subsequent blood and/or catheter infection was completely prevented, suggesting a selective effect of EGF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
