Small bowel disease

Alexandre Haumann, Sarah Ongaro, Olivier Detry, Paul Meunier, Michel Meurisse
INTRODUCTION: Small bowel obstruction (SBO) is a common presentation to emergency abdominal surgery. The most frequent causes of SBO are congenital, postoperative adhesions, abdominal wall hernia, internal hernia and malignancy. PATIENTS: A 27-year-old woman was hospitalized because of acute abdominal pain, blockage of gases and stools associated with vomiting. Abdominal computed tomography showed an acute small bowel obstruction without any obvious etiology. In view of important abdominal pain and the lack of clear diagnosis, an explorative laparoscopy was performed...

BACKGROUND AND STUDY AIMS: Small bowel ulceration poses a limited, but difficult differential diagnosis. The most common causes are Crohn's disease (CD), NSAID-associated enteritis, lymphoma, cytomegaly virus infection and tuberculosis. A less known and relatively novel differential diagnosis is cryptogenic multifocal ulcerative stenosing enteritis (CMUSE). PATIENTS AND METHODS: ive patients referred for balloon-assisted enteroscopy for various reasons showed endoscopic features of CMUSE...

BACKGROUND: Nowadays, capsule endoscopy is the first-line procedure for the visualization of the small bowel. Although it was primarily designed with this goal, it may also identify other segments of the gastrointestinal tract. The aim of the current study is to evaluate the incidence of esophageal abnormalities detected in patients undergoing small bowel capsule endoscopy and its impact on patient management. PATIENTS AND METHODS: This study is a retrospective analysis of data from 2217 consecutive capsule endoscopy procedures performed at a single tertiary-care centre between January 2008 and February 2016...

BACKGROUND: Neuroendocrine tumors (NETs) have a uniquely indolent biology. Management focuses on tumor and hormonal burden reduction. Data on cytoreduction with extrahepatic disease remain limited. OBJECTIVE: We sought to define the outcomes of cytoreduction for metastatic NETs with extrahepatic metastases. METHODS: Patients undergoing cytoreductive surgery for grade 1 or 2 NETs with extrahepatic metastases (with or without intrahepatic disease) were identified from an institutional database (2003-2014)...

Receptor interacting protein kinase 2 (RIP2 or RICK herein referred to as RIPK2) is linked to the pathogen pathway that activates NFkB and autophagic activation. Using molecular modeling (docking) and chemoinformatics analyses we utilized the RIPK2/ponatinib crystal structure and searched in chemical databases for small molecules exerting binding interactions similar to those exerted by ponatinib. The identified RIPK2 inhibitors potently inhibited the proliferation of cancer cells by > 70% as well as inhibition of NFkB activity...

The mucosal response to injury can best be understood as a complex layering of different responses that may be invoked depending upon the size and nature of the injury, the persistence of the injurious stimulus, and the availability of various trophic host factors that stimulate repair. There is a hierarchy of responses that ranges from small rapid resealing of acute apical membrane or single cell wounds through the long term attempt to heal a giant peptic ulcer or respond to inflammatory bowel disease. Although much previous attention has been paid to the local factors that regulate these pathways and responses, there is increasing interest in systemic factors that may act either by the production of cytokines and trophic factors or by the direct migration of bone marrow derived stem cells into the mucosal wound...

INTRODUCTION: Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed...

Inflammatory bowel disease encompasses a group of chronic-inflammatory conditions of the colon and small intestine. These conditions are characterized by exacerbated inflammation of the organ that greatly affects the quality of life of patients. Molecular mechanisms counteracting this hyperinflammatory status of the gut offer strategies for therapeutic intervention. Among these regulatory molecules is the anti-inflammatory cytokine interleukin (IL)-10, as shown in mice and humans. Indeed, IL-10 signaling, particularly in macrophages, is essential for intestinal homeostasis...

Death receptor 3 (DR3), a member of the tumor necrosis factor receptor (TNFR) superfamily, has been implicated in regulating T-helper type-1 (TH 1), type-2 (TH 2), and type-17 (TH 17) responses as well as regulatory T cell (Treg ) and innate lymphoid cell (ILC) functions during immune-mediated diseases. However, the role of DR3 in controlling lymphocyte functions in inflammatory bowel disease (IBD) is not fully understood. Recent studies have shown that activation of DR3 signaling modulates Treg expansion suggesting that stimulation of DR3 represents a potential therapeutic target in human inflammatory diseases, including Crohn's disease (CD)...

The pharmacological management of inflammatory bowel disease (IBD) over the last two decades has transitioned from reliance on aminosalycilates, corticosteroids and immunomodulators to earlier treatment with anti-tumor necrosis factor (anti-TNF) therapy. Nevertheless, 20-30% of patients discontinue anti-TNF therapy for primary non-response and another 30-40% for losing response within one year of treatment. These undesirable therapeutic outcomes can be attributed to pharmacokinetic (anti-drug antibodies and/or low drug concentrations) or pharmacodynamic issues characterized by a non-TNF driven inflammation...

AIM: Analogues of several gastrointestinal peptide hormones have been developed into effective medicines for treatment of diseases such as type 2 diabetes mellitus (T2DM), obesity and short bowel syndrome (SBS). In this study, we aimed to explore whether the combination of glucagon-like peptide-1 (GLP-1) and glucagon-like peptide-2 (GLP-2) into a potent co-agonist could provide additional benefits compared to existing monotherapies. METHODS: A short-acting (GUB09-123) and a half-life extended (GUB09-145) GLP-1/GLP-2 co-agonist were generated using solid-phase peptide synthesis and tested for effects on food intake, body weight, glucose homeostasis, and gut proliferation in lean mice and in diabetic db/db mice...

Introduction: Gastrointestinal histoplasmosis (GH) is a well-described albeit uncommon disease. It is found almost exclusively in the immunocompromised host, especially those with untreated HIV and low CD4 counts. Presentation with intestinal perforation is seen mostly commonly in the colon. We present a patient with jejunal perforation, and there have been only 3 previous cases reported in the literature. Case: A 39-year-old male with known, untreated HIV presented to the ED with an acute abdomen after experiencing worsening intermittent abdominal pain for 2 months before that was associated with nausea, vomiting, diarrhea, and weight loss...

Inflammatory bowel disease (IBD) is a collection of inflammatory conditions of colon and small intestine which affect millions of individuals worldwide and the prevalence amount is on the rise. The organ failure as well as loss of tissue function is because of the inflammatory reaction which is the major contributor of tissue healing leading to lifelong debilitation. To stop the tough consequences of inflammation every patient pursues alternative therapy to relieve symptoms. Green tea polyphenols (GTPs) play significant roles in down regulating signaling pathways because GTPs exert effective antioxidant properties and regulate Toll-like receptor 4 (TLR4) expression via certain receptor, inhibited endotoxin-mediated tumor necrosis factor alpha (TNF-α) production by blocking transcription nuclear factor-kappa B (NF-kB) activation and upstream of mediated I kappa B kinase complex pathway activities, as well as intrusion with the flow of cytokines and synthesis of cyclooxygenase-2 (COX-2)...
