Filter by:Surgical procedures for complex intestinal neonatal and paediatric diseases may require the use of an ostomy, in order to discharge the upper intestine. The traditional loop ileostomy has recently be challenged by ileostomies in continuity, either the Santulli or the Bishop-Koop one, that both decompresses the proximal dilated bowel and allow intestine fluid to pass through the underlying ileal anastomosis. Nevertheless, to date, no evaluation of their indications, complications and potential benefits has been made. The aim of this study is to retrospectively compare the outcomes of loop ileostomies and ileostomies in continuity in a paediatric population. It is thus expected to better define the specific indications for these different types of ileostomies in the paediatric and neonatal population.
Hirschsprung's disease (HD) is a rare disease defined as a congenital absence of enteric ganglia, resulting usually in neonatal bowel obstruction. The current treatment is the operative removal of the aganglionic bowel and anastomosis to the ganglionic zone considered as 'healthy'. However, postoperative course remains unpredictable. Functional intestinal disorders are present in up to 45% of patients and can occur in the immediate postoperative period or few weeks/years later. Until now, there are neither predictive factors of postoperative digestive complications nor established treatment for postoperative dysmotility in HD. Abnormalities in enteric nervous system (ENS) phenotype and functions in the 'healthy' ganglionic segment are increasingly suspected to be directly responsible for postoperative intestinal dysfunctions in HD. Therefore, approaches aimed at restoring the nitrergic phenotype could be of major therapeutical interest. Among targets regulating the nitrergic phenotype of ENS are the microbiota and/or derived metabolites. Indeed preclinical animal models deficient in bacterial sensing molecules have a loss of nitrergic neurons and reduced colonic transit. Conversely, microbiota transfer to newborn germ-free mice restored colonic transit time. Alternatively the investigators has shown that bacterial metabolites such as short-chain fatty acids, in particular butyrate, can increase nitrergic phenotype and enhance colonic motility in a gut immaturity animal model. Therefore the investigators hypothesize preoperative butyrate enema will reduce postoperative intestinal complications at short-term and medium/long-term.
Infections after elective intestinal surgery remain a significant burden for patients and for the health care system. The cost of treating a single surgical site infection is estimated at approximately $27,000. In adult patients, there is good evidence that the combination of oral antibiotics and mechanical bowel preparation is effective at reducing infections after intestinal surgery. In children, the body of evidence is much weaker. In this population, little evidence exists for oral antibiotics reducing infections and no data exists as to the effect of combining antibiotics with mechanical bowel preparation (such as polyethylene glycol (PEG)). The goal of the proposed study is to examine the effects of oral antibiotics with and without the combined use of mechanical bowel preparation on the rate of post-operative infectious complications in children aged 6 months to 18 years. This will be compared to the institution's current standard of care, which is to abstain from any type of mechanical bowel preparations or oral antibiotic administration before intestinal surgery.
To evaluate the outcomes of laparoscopic pull-through concerning constipation, incontinence and enterocolitis in comparison of other surgical procedures for treatment of Hirschsprung disease.
Children with chronic constipation, suspected of having hirschsprungs disease, who are admitted for rectal biopsy will be included in the study. During the procedure, electrophysiological reading from the site chosen for biopsy will be done. Correlation between electrophysiological data and histopathology will be analyzed.
