Use of covered self-expandable stents for benign colorectal disorders in children.

PURPOSE: There is a lack of experience with covered self-expandable stents for benign colorectal disorders in children. METHODS: Five children (4M, 1F) with a median age of 5years (range, 6months-9years) who underwent treatment with covered self-expandable plastic (SEPSs) or self-expandable metal stents (SEMSs) for a benign colorectal condition between April 2005 and November 2013 were recruited to this retrospective study. Etiologies included: anastomotic stricture with (n=1) or without (n=3) simultaneous enterocutaneous fistula, as well as an anastomotic leak associated with enterocutaneous

Correlation between Polymorphisms of Vitamin D Metabolism Genes and Perianal Disease in Crohn's Disease.

Although the role of vitamin D (VD) in the pathogenesis and progression of Crohn's disease (CD) is known, the association between single-nucleotide polymorphisms (SNPs) of genes linked to vitamin D pathway and CD risk is still under study. Furthermore, no significant association has been previously found between these SNPs and perianal CD (pCD), a severe phenotypic manifestation of CD that may present as perianal fistula, abscess, and recto-vaginal fistula. Among the mechanisms involved in its pathogenesis, local inflammation and intestinal microbiota alteration are recognized. VD seems to act

… Two different studies analyzed the genetic factors associated with the development of perianal fistulas and intestinal fistulas and had different results [ 20 , 21 ]. …

Significance of diffusion weighted imaging (DWI) as an improving factor in contrast enhanced magnetic resonance imaging (MRI) enterography in evaluation of patients with Crohn's disease.

Aim To determine capabilities and potential of contrast enhanced magnetic resonance imaging (MRI) enterography in order to establish the diagnosis and to evaluate severity and activity of intestinal inflammation. Methods Fifty-five patients with suspicion for presence of Crohn's disease were evaluated. All patients underwent contrast enhanced MRI enterography and diffusion weighted imaging (DWI), and subsequently endoscopic examination or surgical treatment. Four parameters were analysed: thickening of the bowel wall, and presence of abscess, fistula and lymphadenopathy. Results Comparing resu

Repair of congenital esophageal atresia with tracheoesophageal fistula repair in Ontario over the last 20years: Volume and outcomes.

BACKGROUND/PURPOSE: This study was designed to determine the volume, postoperative surgical outcomes and, if possible, the relationship between outcome and institutional / surgeon volume in neonates undergoing repair of esophageal atresia with tracheoesophageal fistula (EA-TEF) over the last 20years in Ontario. METHODS: Using administrative databases, a population based cohort study of patients undergoing EA-TEF repair in Ontario between 1993 and 2012 was conducted. RESULTS: 465 patients with the diagnosis of EA-TEF met inclusion criteria. The mean number of EA-TEF repairs per year per was 5

Anorectal malformations caused by defects in sonic hedgehog signaling.

Anorectal malformations are a common clinical problem affecting the development of the distal hindgut in infants. The spectrum of anorectal malformations ranges from the mildly stenotic anus to imperforate anus with a fistula between the urinary and intestinal tracts to the most severe form, persistent cloaca. The etiology, embryology, and pathogenesis of anorectal malformations are poorly understood and controversial. Sonic hedgehog (Shh) is an endoderm-derived signaling molecule that induces mesodermal gene expression in the chick hindgut. However, the role of Shh signaling in mammalian hind

Indications, strategy and results of surgical management in 141 cases of Crohn's disease.

Of 200 cases of CD observed in the course of twenty years, 141 (70.5%) have been treated by surgery. At the time of surgery, 6 patients had duodenitis, 87 ileitis, 35 ileocolitis, 9 colitis and 8 proctocolitis. In 4 cases the duodenum and ileum were simultaneously involved. Complications of the disease and failure of medical treatment represented the indications for surgery. Elective surgery was possible in 74.5% of cases. Intestinal resection was performed in all cases except for 6 by-passes (4 for duodenal obstruction) and 3 external derivations (1 ileostomy for perforation, and 2 colostomie

Initial Clinical Outcomes Using Umbilical Cord-Derived Tissue Grafts to Repair Anovaginal Fistula.

BACKGROUND: Perianal fistula is a debilitating disease and challenging condition to treat. Recently, the use of stem cells has been shown to improve healing of fistulas. OBJECTIVE: The aim was to examine the use of an umbilical cord-derived stem cell graft in a pilot study as a novel scaffold/stem inlay implanted into fistula repairs for anovaginal fistula to examine healing rates. DESIGN: This was a pilot study. SETTINGS: This study took place in a colorectal surgery practice. PATIENTS: Patients with anovaginal fistula consented to participate. Cryopreserved umbilical cord tissue graft wi

[Primary aortoduodenal fistula - a rare cause of life-threatening upper gastrointestinal bleeding].

OBJECTIVES: To characterise the key epidemiological, clinical, immunological, imaging, and pathological features of the coexistence between sarcoidosis and spondyloarthritis (SpA). METHODS: All centres included in two large multicentre registries (the Sjögren Syndrome Big Data Consortium and the Sarco-GEAS-SEMI Registry) identified potential cases of coexisting SpA and sarcoidosis. Inclusion criteria were the fulfilment of the current classification criteria both for SpA (ASAS) and sarcoidosis (WASOG). RESULTS: We identified twenty-three patients (14 females and 9 males) with a mean age of 4

Colovesical fistula in men with chronic urinary tract infection: A diagnostic challenge.

Although uncommon, colovesical fistula creates significant morbidity, and many patients wait months to receive a correct diagnosis and treatment. Most cases are in older men who have diverticular disease, Crohn disease, cancer, or iatrogenic injury, and some of these associations may have occurred in the patient's distant past and may not be immediately apparent. Since the incidence of diverticulitis in elderly patients is increasing and, in a separate trend, more patients are undergoing bladder instrumentation, we need to suspect this diagnosis when evaluating any patient with urinary tract i
