Inflammatory bowel disease (IBD) is caused by a dysregulation of the immune system, inducing the production of proinflammatory cytokines and adhesion molecules. A better understanding of the mucosal immune response in IBD has led to the development of new drugs directed at inflammatory cytokines and leukocyte-trafficking molecules. Beyond tumor necrosis factor antagonists and anti-integrin molecules, which act by blocking the interaction between gut-specific lymphocytes and their receptor on vascular endothelium, the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway represents a new target in IBD...

Over the recent years the non-invasive techniques for the evaluation of the small bowel have been playing a major role in the management of chronic intestinal diseases, such as inflammatory bowel diseases (IBD). The diagnostic performances of magnetic resonance imaging, computed tomography and ultrasound in the field of small bowel disorders, have been assessed and established for more than two decades. Newer sonographic techniques, such as strain elastography and shear wave elastography, have been put forward for the assessment of disease activity and characterization of IBD-related damage in the setting of Crohn's disease and other gastrointestinal disorders...

BACKGROUND: Oxaliplatin in combination with either 5-fluorouracil or capecitabine is commonly used as first-line therapy for patients with small bowel adenocarcinoma. The addition of irinotecan improves survival in other gastrointestinal tumors but at the cost of hematologic toxicity. The authors performed a phase 2 cooperative group study (North Central Cancer Treatment Group N0543, Alliance) using genotype-dosed capecitabine, irinotecan, and oxaliplatin (gCAPIRINOX), with dosing assigned based on UDP glucuronosyltransferase family 1 member A1 (UGT1A1) genotype to test: 1) whether the addition of irinotecan would improve outcomes; and 2) whether UGT1A1 genotype-based dosing could optimize tolerability...

Stereotactic body radiation therapy (SBRT) is delivered in a curative intent to many primary and secondary tumors. Concerning liver metastasis, SBRT can be safely delivered using one to five fractions. An excellent local control is obtained with doses from 20 to 60 Gy. For primary hepatic tumors, results are also good, but the risk of hepatic toxicity related to liver pre-existent pathology must be taken into account. Radiation induced liver disease (RILD) is not frequent in its classical presentation, but modifications of liver enzymes are often observed...

BACKGROUND: Ewing's sarcoma (ES) and primitive neuroectodermal tumors (PNET) are closely related tumors. Although soft tissue ES/PNET are common in clinical practice, they are rare in the small intestine. Because of the absence of characteristic clinical symptoms, they are easily misdiagnosed as other benign or malignant diseases. CASE PRESENTATION: Here, we present the case of a 16-year-old female who complained of anemia and interval hematochezia. Her serum test results showed only a slight elevation of CA-125 and a low level of hemoglobin...

Primary sclerosing cholangitis (PSC) is a disease of the biliary tract, which has been documented in the literature since 1867. This disease has a strong predilection for affecting men and can be seen in individuals as young as 2 years of age. PSC has a strong associated with inflammatory bowel disease, more commonly with ulcerative colitis, and is also part of the clinical spectrum of IgG4-related diseases. Small-duct PSC, a variant of PSC, also has an association with inflammatory bowel disease. The exact pathogenesis of PSC is not well understood at present, however, is likely a combination of a genetic predisposition with alteration of the molecular structure of the gut...

Gastrointestinal stromal tumor (GIST) is a rare stromal neoplasm, which represents the most common mesenchymal tumor of the gastrointestinal tract. It is characterized by indolent clinical symptoms, although it can present as a life-threatening emergency. Herein, we present two cases of primary small bowel GIST treated at our department. A 68-year-old female patient presented to our emergency department with a diffuse abdominal pain of acute onset. Imaging studies revealed a mass at proximal jejunum, with a nearby free air and fluid...

Intussusception in adults lacks specific symptoms and is often diagnosed emergently when they present with obstruction. Though intussusception certainly varies in size and location, the increased likelihood of ischemia or obstruction make large intussusceptions very rare in the literature. A patient admitted to our facility for small bowel obstruction was found to have extensive intussusception from the right lower quadrant to the splenic flexure, where a lead point was identified. Histopathology revealed multiple satellite lesions surrounding the lead point tumor, which was found to be invasive mucinous adenocarcinoma of the ileocecal valve...

We present a case of male patient, who was referred to our department because of acute intestinal obstruction, which was the initial clinical symptom of primary lung cancer. The abdominal computed tomography (CT) prior to the emergency operation showed small intestinal obstruction and metastases to both adrenal glands. The patient underwent an emergency abdominal exploratory laparotomy, that confirmed small bowel obstruction and diffuse metastatic lesions along the entire small bowel length. During the operation we took a sample of one metastasis for pathological examination and we created an intestinal bypass to relieve small bowel obstruction...

Small bowel injury can occur as the result of a multifaceted process that includes increased acid secretion, generation of reactive oxygen species, and cyclooxygenase inhibition. However, no effective medication for small bowel ulceration is available. Simvastatin is an important lipid-lowering agent with anti-inflammatory activity. We aimed to validate the effects of simvastatin in vitro and in vivo. In presence or absence of simvastatin, IEC-6 small bowel cell line with 50 ng/ml of tumor nectosis factor α (TNF-α) was investigated by western blotting, qRT-PCR, and DCF-DA assay...

Nicholas J Talley
Functional dyspepsia (FD) is a common but under-recognized syndrome comprising bothersome recurrent postprandial fullness, early satiety, or epigastric pain/burning. Epidemiologically, there are two clinically distinct FD syndromes (although these often overlap clinically): postprandial distress syndrome (PDS; comprising early satiety or meal-related fullness) and epigastric pain syndrome. Symptoms of gastroesophageal reflux disease overlap with FD more than expected by chance; a subset has pathological acid reflux...

Capsule endoscopy is the diagnostic test of choice for the evaluation of overt and occult small bowel bleeding. Its yield is higher in patients presenting with overt bleeding. The yield is also improved if the capsule is performed soon after the presentation of bleeding. Capsule endoscopy has a complementary role with cross-sectional imaging to triage patients for appropriate management, including deep enteroscopy, surgery, or, if negative, conservative management. Although capsule endoscopy is useful to detect vascular and inflammatory lesions, it appears to have a significant miss rate for solitary small bowel lesions, including tumors...

Primary small bowel tumors account for 1-6% of all Gastrointestinal (G.I.) tract malignancies. Among these pedunculated lipomas are unusual. We report a case of a 66-year-old male with a history of G.I. hemorrhage and acute anemia, negative upper and lower endoscopies and a pedunculated lipoma in distal ileum, revealed by CT enterography. The patient was successfully treated by open surgery. Patients with G.I. hemorrhage and negative upper and lower endoscopies need an accurate evaluation of small bowel. Multislice CT enterography or Magnetic Resonance enteroclysis/ enterography represent the fastest and more accurate tools to obtain an exhaustive evaluation of small bowel...

Small bowel adenocarcinoma (SBAC) accounts for 3% of all gastrointestinal tract tumors and approximately 0.5% of all cancer cases. Recent studies have indicated that the use of metformin, one of the most commonly prescribed antidiabetic drugs, is associated with a better prognosis for certain malignant diseases. However, there have been no reports on the effect of metformin in SBAC. In the present study, we evaluated the effect of metformin on human SBAC cell proliferation in vitro and in vivo and identified the microRNAs (miRNAs) associated with its antitumor effects...

Wireless capsule endoscopy (WCE) is a powerful tool for medical screening and diagnosis, where a small capsule is swallowed and moved by means of natural peristalsis and gravity through the human gastrointestinal (GI) tract. The camera-integrated capsule allows for visualization of the small intestine, a region which was previously inaccessible to classical flexible endoscopy. As a diagnostic tool, it allows to localize the sources of bleedings in the middle-part of the gastrointestinal tract and to identify diseases such as inflammatory bowel disease (Crohn's disease), Polyposis-Syndrome and tumors...

BACKGROUND AND AIMS: Enteroscopy (wireless, wired) is the reference standard for small-bowel (SB) diseases and it has been applied to detect SB malignancies in complicated celiac disease (CD) with heterogeneous results. The aim of this meta-analysis is to obtain a diagnostic yield (DY) by pooling the data of studies that investigated the use of enteroscopy to detect SB adverse events in CD. METHODS: We performed an online search for studies estimating the DY of wireless and wired enteroscopy in predicting the presence of SB pre-malignant and/or malignant lesions...

HuR is an RNA-binding protein implicated in immune homeostasis and various cancers, including colorectal cancer. HuR binding to AU-rich elements within the 3' untranslated region of mRNAs encoding oncogenes, growth factors, and various cytokines leads message stability and translation. In this study, we evaluated HuR as a small-molecule target for preventing colorectal cancer in high-risk groups such as those with familial adenomatosis polyposis (FAP) or inflammatory bowel disease (IBD). In human specimens, levels of cytoplasmic HuR were increased in colonic epithelial cells from patients with IBD, IBD-cancer, FAP-adenoma, and colorectal cancer, but not in patients with IBD-dysplasia...
