Endoscopic-assisted colopexy and push percutaneous colostomy in the transverse colon for refractory chronic intestinal pseudo-obstruction.

Percutaneous endoscopic colostomy (PEC), using the classic pull-through technique in the ascending or the descending colon, has been proven useful to treat chronic intestinal pseudo-obstruction. We report the case of a high-surgical risk 70-year-old male with refractory chronic intestinal pseudo-obstruction, in whom the ascending colon could not be reached due to tortuous left dolichocolon. Endoscopic-assisted colopexy and push colostomy in the proximal transverse colon was decided accordingly. Colopexy was performed under direct endoscopic vision in the proximal transverse colon using 3 preloaded T-fasteners surrounding the intended stoma site. The stoma tract was created with an introducer needle, allowing the advance of the 24 Fr 4-sleeve dilator over a guidewire. Afterwards, the dilator was removed and the peel-away sheath was left in place. Over the guidewire, a 20-Fr gastrostomy tube was advanced into the colon lumen through the covering, which was finally removed. The patient recovered uneventfully, despite postprocedure pneumoperitoneum, which was related to the technique. He died a month later due to unrelated comorbidities, without further abdominal complaints after discharge. This is the first report of PEC both using a push technique, and the first report in a different location than the ascending or the descending colon. We believe this novel push technique may be feasible for PEC, avoiding the need of reinsertion in patients with difficult colonoscopy.

HLA-DQ: Celiac disease vs inflammatory bowel disease

AIM To determine the genetic predisposition to celiac disease (CeD) in inflammatory bowel disease (IBD) patients by quantifying the frequency of CeD-related human leucocyte antigen (HLA) (HLA-CeD: HLA-DQ2 and -DQ8) in IBD patients globally, by type of IBD and gender, and by calculating the protective/risk contribution of these haplotypes in the development of the IBD disease. METHODS We conducted a prospective study with IBD patients from our Unit. Clinical information was gathered and blood was tested for HLA-CeD. The control group was made up of unrelated Valencian organ donors. RESULTS 1034 subjects were analyzed: 457 IBD [207 ulcerative coliti (UC) and 250 Crohn’s disease (CD)] patients and 577 healthy controls. 39% of the controls and 34% of the patients had HLA-CeD (P = 0.0852). HLA-DQ2 was less frequent in UC patients (P = 0.0287), and HLA-DQ8 in CD (P = 0.0217). In women with UC, the frequency of DQ2.5cis (DQB1*02:01-DQA1*05:01) was reduced ≥ 50% [P = 0.0344; preventive fraction (PF) = 13%]. PFs (7%-14%) were obtained with all HLA-CeD haplotypes. HLA DQB1*02:02-DQA1*02:01 (HLA-DQ2.2) was more frequent in CD patients with respect to controls (P = 0.001) and UC patients (etiological fraction = 15%). CONCLUSION HLA-CeD is not more frequent in IBD patients, with an even lower frequency of HLA-DQ2 and -DQ8 in UC and CD respectively. HLA-DQ2.5 confers protection from the development of UC, especially in women, and HLA-DQ8 does so for the appearance of CD. HLA-DQ2.2 is present in 34% of the CD patients and may constitute a genetic risk factor for CD development.

central review of endoscopic images on patient selection and trial outcomes. Methods: We utilized data from a placebo-controlled randomized trial of Asacol®, an 800mg formulation of mesalamine, conducted in patients with mildly-to-moderately active UC (NCT01059344). Eligible patients had a UC-DAI total score of 4 10 and an endoscopy sub-score 2. Patients were randomized 1:1 to Asacol® 4.8 g/day or placebo for 10 weeks. Outcomes were assessed at weeks 6 and 10. Post-hoc exploratory analyses compared week 6 clinical and endoscopic outcomes in site investigator (SI)and central reader (CR)-defined endoscopically eligible populations, as well as outcomes in CReligible patients using SI versus CR scoring. Results: A total of 281 patients comprised the SI population. Of these, 194 (69%) were considered eligible by the CR and were included in CR-based analyses. The effect size (percent difference Asacol® minus placebo) was consistently greater for all outcomes in the CR-versus SI-defined population (see Table 1). Placebo rates were uniformly greater in the SI population due to inclusion of patients with low endoscopic disease activity as judged by the CR. No difference in effect size was observed between CRand SI-based outcomes at week 6 in the CR-defined population.
