    Background: Sclerosing mesenteritis (SM) is sometimes used as an umbrella-term for idiopathic inflammatory conditions in the mesentery. Mesenteric panniculitis (MP) is a radiological finding and its relation to clinical SM is not fully understood. The aims of this study were to determine whether any correlation could be found between the radiological findings and the clinical disease course. Read More

    Alteration of gut microbiota in association with cholesterol gallstone formation in mice.
    BMC Gastroenterol 2017 Jun 9;17(1):74. Epub 2017 Jun 9.
    Institute of Gallstone Disease, Center of Gallbladder Disease, Shanghai East Hospital, Tongji University School of Medicine, #150 Jimo Road, Shanghai, 201200, China.
    Background: The gut microbiome exerts extensive roles in metabolism of nutrients, pharmaceuticals, organic chemicals. Little has been known for the role of gut microbiota in regulating cholesterol and bile acids in association with gallstone formation. This study investigated the changes in the composition of gut microbiota in mice fed with lithogenic diet (LD). Read More

    Anti-fibrogenic effect of PPAR-γ agonists in human intestinal myofibroblasts.
    BMC Gastroenterol 2017 Jun 7;17(1):73. Epub 2017 Jun 7.
    Digestive Disease Center, CHA Bundang Medical Center, CHA University, 59 Yatap-ro, Bundang-gu, Seongnam, 463-712, South Korea.
    Background: Intestinal fibrosis is a serious complication of inflammatory bowel disease, including Crohn's disease and ulcerative colitis. There is no specific treatment for intestinal fibrosis. Studies have indicated that peroxisome proliferator-activated receptor- γ (PPAR-γ) agonists have anti-fibrogenic properties in organs besides the gut; however, their effects on human intestinal fibrosis are poorly understood.

    Incomplete ileus and hemafecia as the presenting features of multi-organ involved primary systemic AL amyloidosis: a rare case report.
    BMC Gastroenterol 2017 Jun 5;17(1):72. Epub 2017 Jun 5.
    The Third Xiangya Hospital of Central South University, 138 Tongzipo Road, Yuelu District Changsha, Hunan, 410013, China.
    Background: AL Amyloidosis is known to be a systemic disease affecting multiple organs and tissue while it's rare that patients present with gastrointestinal symptoms at first and later develop multiple-organ dysfuction. Clinical signs are not specific and the diagnosis is rarely given before performing immunofixation and endoscopy with multiple biopsies. We would like to emphasize the value of precise diagnostic process of AL amyloidosis. Read More

    Clinicopathological features and surgical outcomes of neuroendocrine tumors of ampulla of Vater.
    BMC Gastroenterol 2017 May 31;17(1):70. Epub 2017 May 31.
    Department of Surgery, Biomedical Research Institute, Pusan National University Hospital, 179, Gudeok-Ro, Seo-Gu, Busan, 602-739, South Korea.
    Background: The study aims to investigate the clinicopathological features and surgical outcomes of neuroendocrine tumors of ampulla of Vater (NETAoVs) patients who underwent pancreaticoduodenectomy.

    Methods: From January 2007 to December 2014, 45 patients underwent pancreaticoduodenectomy for malignant disease of the ampulla of Vater in our institution. Of those, 5 patients were diagnosed as neuroendocrine tumors. Read More

    Optimal timing of cholecystectomy after percutaneous gallbladder drainage for severe cholecystitis.
    BMC Gastroenterol 2017 May 31;17(1):71. Epub 2017 May 31.
    Department of surgery, South Miyagi Medical Center, 38-1 Aza-nishi, Ogawara, Shibata-gun, Miyagi, 989-1253, Japan.
    Background: The Tokyo guideline for acute cholecystitis recommended percutaneous transhepatic gallbladder drainage followed by cholecystectomy for severe acute cholecystitis, but the optimal timing for the subsequent cholecystectomy remains controversial.

    Methods: Sixty-seven patients who underwent either laparoscopic or open cholecystectomy after percutaneous transhepatic gallbladder drainage for severe acute cholecystitis were enrolled and divided into difficult cholecystectomy (group A) and non-difficult cholecystectomy (group B). Patients who had one of these conditions were placed in group A: 1) conversion from laparoscopic to open cholecystectomy; 2) subtotal cholecystectomy and/or mucoclasis; 3) necrotizing cholecystitis or pericholecystic abscess formation; 4) tight adhesions around the gallbladder neck; and 5) unsuccessfully treated using PTGBD.

    Therapeutic outcomes of endoscopic papillectomy for ampullary neoplasms: retrospective analysis of a multicenter study.
    BMC Gastroenterol 2017 May 30;17(1):69. Epub 2017 May 30.
    Department of Internal Medicine, Daegu Fatima Hospital, Daegu, South Korea.
    Background: Endoscopic papillectomy (EP) is reported to be a relatively safe and reliable procedure for complete resection of ampullary neoplasms. The aim of this study was to evaluate the therapeutic outcomes and complications of EP for ampullary neoplasms.

    Methods: A retrospective multicenter study was conducted with 5 participating centers from January 2007 to July 2014. Read More

    Genetic variation and expression levels of tight junction genes identifies association between MAGI3 and inflammatory bowel disease.
    BMC Gastroenterol 2017 May 25;17(1):68. Epub 2017 May 25.
    Division of Medical Diagnostics, Region Jönköping County, Jönköping, Sweden.
    Background: Inflammatory bowel disease (IBD) is associated with increased intestinal permeability, which involves paracellular passage regulated through tight junctions (TJ). The aim of the study was to investigate single nucleotide polymorphisms (SNP) located in genes encoding interacting TJ proteins and corresponding expressions, in relation to IBD.

    Methods: Allelic associations between TJ-related genes (F11R, MAGI1, MAGI2, MAGI3, PARD3, PTEN, and TJP1) and IBD, Crohn's disease (CD), or ulcerative colitis (UC) were investigated. Read More

    Comparison of oesophageal function tests between Chinese non-erosive reflux disease and reflux hypersensitivity patients.
    BMC Gastroenterol 2017 May 23;17(1):67. Epub 2017 May 23.
    Digestive Department, Beijing Anzhen Hospital,Capital Medical University, Beijing, 100029, China.
    Background: By means of 24 h multi-channel intraluminal impedance and pH recording (MII/pH), patients with heartburn and normal upper gastrointestinal endoscopy findings can be classified into those with non-erosive reflux disease (NERD) and those with reflux hypersensitivity (RH). Therefore, in this study, we investigated the difference in oesophageal function tests in Chinese patients with NERD and RH.

    Methods: NERD patients were selected from the digestive department, Beijing Anzhen Hospital and Beijing Chao-Yang Hospital, Capital Medical University, after upper gastrointestinal endoscope, high-resolution manometry and impedance (HRiM), and MII/pH examinations between 2014 and 2016.
