BACKGROUND: Complete cytoreductive surgery (CCRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a validated treatment in selected patients with peritoneal metastases (PM) of intestinal origin. There is an increased risk of Colorectal Cancer (CRC) and Small Bowel Adenocarcinoma (SBA) in Inflammatory Bowel Disease (IBD). The feasibility and benefit of that surgical approach in IBD patients is unknown. METHODS: IBD patients with operated PM complicating CRC or SBA were extracted from a French national multicenter prospective database of patients who underwent surgery for PM in HIPEC expert centers from 1995 to 2016...

Inflammatory bowel disease (IBD) consists of ulcerative colitis (UC) and Crohn's disease (CD). Natural killer cell responses play a crucial role in autoimmune disease through innate immunity, in which killer cell immunoglobulin-like receptors (KIRs) are closely involved. Although the genetic combination of KIRs with their specific HLA class I ligands has been associated with IBD in Caucasians, such KIR-HLA receptor-ligand combinations are not fully understood in the Japanese. We investigated 14 KIR genes along with HLA-Bw and -C ligands in 90 patients with UC and 50 patients with CD and compared them with the characteristics of 325 healthy control subjects...

Mucus is characterized by multiple levels of assembly at different length scales which result in a unique set of rheological (flow) and mechanical properties. These physical properties determine its biological function as a highly selective barrier for transport of water and nutrients, while blocking penetration of pathogens and foreign particles. Altered integrity of the mucus layer in the small intestine has been associated with a number of gastrointestinal tract pathologies such as Crohn's disease and cystic fibrosis...

BACKGROUND Superior mesenteric artery syndrome is caused by vascular compression of the third portion of the duodenum between the aorta and the superior mesenteric artery. It may occur with acute or chronic symptomatology, such as vomiting or postprandial abdominal pain, and it is usually caused by a lack of mesenteric fat pad under conditions of severe weight loss. Crohn's disease can be one of them. CASE REPORT We report 2 cases of Crohn's disease patients with clinical suspicion of jejunal stricture who underwent MR-enterography with a novel approach...

Rasmussen's encephalitis (RE) is a chronic inflammatory brain disorder that causes frequent seizures and unilateral hemispheric atrophy with progressive neurological deficits. Hemispherectomy remains the only treatment that leads to seizure freedom for this refractory epileptic syndrome. The absence of an animal model of disease has been a major obstacle hampering the development of effective therapies. Here, we describe an experimental mouse model that shares several clinical and pathological features with the human disease...

Every anesthesia provider fears aspiration of gastric contents during an anesthetic, and it may occur even in the absence of overt signs such as coughing or choking. Whether the aspiration is frank or silent, catastrophic and deleterious consequences may ensue. Therefore, familiarity with risk factors for silent aspiration is essential. Crohn's disease reportedly delays gastric emptying making these patients more susceptible to silent aspiration during surgery. Anesthesia providers must be cognizant of this risk and vigilant in the recognition to formulate a specific treatment plan preoperatively...

G Protein Coupled Receptor 109A (GPR109A), which belongs to the G protein coupled receptor family, can be activated by niacin, butyrate, and β-hydroxybutyric acid. Here, we assessed the anti-inflammatory activity of sodium butyrate (SB) on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis mice, an experimental model that resembles Crohn's disease, and explored the potential mechanism of SB in inflammatory bowel disease (IBD). In vivo, experimental GPR109a-/- and wild-type (WT) mice were administered SB (5g/L) in their drinking water for 6weeks...

Macrophages belong to the mononuclear phagocyte system comprising closely related cells of bone marrow origin. Activated macrophages are critical in several diseases such as tuberculosis, sarcoidosis, Crohn's disease, and atherosclerosis. Noninvasive imaging techniques that can specifically image activated macrophages could therefore help in differentiating various forms of inflammatory diseases and to monitor therapeutic responses.

AIMS: To describe the characteristics of patients with Crohn's disease (CD) in non-academic hospitals in France and to evaluate how therapeutic practices changed between 1999 and 2013. METHODS: During 2 weeks in September 2013, we solicited disease and treatment information for CD patients seen by gastroenterologists in 57 French non-academic hospitals. In four groups of patients defined according to the date of CD diagnosis (<1999, 1999-2003, 2004-2008, and 2009-2013), the use of immunosuppressor (IS) and anti-TNF treatments during the first 5 years following diagnosis of CD was compared using the Kaplan-Meier method...

BACKGROUND: Pelvic MRI allows for clear delineation of anatomy in Crohn's fistula-in-ano, although its interpretation is often difficult for nonradiologists. OBJECTIVE: The aim was to develop a 3-dimensional model where fistula tracts and their relationship to the sphincter complex can be accurately defined, which can then be rotated in multiple axes by the surgeon. DESIGN: A 3-dimensional model was created based on MRI images. An additional 3-dimensional T2-weighted sequence was added to the existing MRI protocol to obtain high-resolution images...

Noninfectious gastrointestinal (GI) vasculopathic disorders are rare and are often overlooked in histopathologic examination or when forming differential diagnoses due to their rarity. However, involvement of the GI tract may lead to serious complications, including ischemia and perforation. Since awareness of the types of vasculopathy that may involve the GI tract is central to arriving at a correct diagnosis, we reviewed our institutional experience with GI tract vasculopathy in order to enhance diagnostic accuracy of these rare lesions...

BACKGROUND: Anti-tumor necrosis factor medications (anti-TNFs) are effective in controlling chronic inflammatory diseases, but information about their use and safety in pregnancy is limited. Consequently, anti-TNFs are often discontinued early in gestation. Certolizumab pegol (CZP), a PEGylated, Fc-free anti-TNF approved for treatment of rheumatic diseases and/or Crohn's disease, has minimal to no active placental transfer. This project provides information on pregnancy outcomes in women receiving CZP, especially those with early pregnancy exposure...

Background: Low anti-tumor necrosis factor α (TNFα) serum concentrations may result in lack of treatment response in patients with inflammatory bowel disease. We determined the anti-TNFα drug concentrations in patients with inflammatory bowel disease and investigated whether or not subtherapeutic drug concentrations were associated with increased levels of disease activity. Methods: In a single-center cross-sectional study, we included patients with ulcerative colitis or Crohn's disease who were receiving infliximab or adalimumab maintenance therapy...

Background: Video capsule endoscopy (VCE) is increasingly performed among the elderly for obscure bleeding. Our aim was to report on the utility of VCE to uncover unsuspected Crohn's disease (CD) in elderly patients. Methods: Retrospective review of VCE performed in elderly patients (≥70 y) at a tertiary hospital (2010-2015). All underwent prior negative bidirectional endoscopies. CD diagnosis was based on consistent endoscopic findings, exclusion of other causes, and a Lewis endoscopic score (LS) > 790 (moderate-to-severe inflammation)...
