In 76 male wistar rats with a median weight of 340 g acute pancreatitis was induced by injection of 2% sodium taurocholate into a temporarily closed duodenal loop. 40 animals received an additional cecostomy (group B), the others served as controls (group A). The postoperative figures for amylase, leucocyte count, and hemoglobin were nearly identical in both groups. According to histologic criteria acute pancreatitis was comparable in both groups, too. In nine rats endotoxin was found elevated postoperatively (13.4%). Seven animals belonged to the control (22.6%) and only two to the cecostomy group (5.6%). The difference was statistically significant (p less than 0.05). Also the differences between the median serum endotoxin levels reached statistic significance (79 ng/l in group B vs. 219 ng/l in group A). Mortality was significantly increased in endotoxin-positive animals (42.9% vs. 19.4%). Additionally, among the animals of the control group alterations of the colonic mucosa were observed more frequently than in the cecostomy group. The results are in favour of a translocation of endotoxin from the gut lumen into the circulation during acute experimental pancreatitis.

Introduction: In neurologically intact children with constipation and lower urinary tract symptoms, treatment of constipation frequently results in improved or resolved lower urinary tract symptoms. The impact of treatment of constipation on bladder function in children with a neurogenic bowel and bladder is not well studied. The objective of this study was to evaluate the impact of antegrade continence enemas (ACE) via Chait tube on urodynamic study (UDS) parameters and urinary continence in patients with neurogenic bowel and bladder (NGB).

A bowel management program (BMP) to treat fecal incontinence and severe constipation is utilized for patients with anorectal malformations, Hirschsprung disease, spinal anomalies, and functional constipation, decreasing the rate of emergency department visits, and hospital admissions. This review is part of a manuscript series and focuses on updates in the use of antegrade flushes for bowel management, as well as organizational aspects, collaborative approach, telemedicine, the importance of family education, and one-year outcomes of the bowel management program. Implementation of a multidisciplinary program involving physicians, nurses, advanced practice providers, coordinators, psychologists, and social workers leads to rapid center growth and enhances surgical referrals.
