    Colorectal endoscopic submucosal dissection: patient selection and special considerations.
    Clin Exp Gastroenterol 2017 13;10:121-131. Epub 2017 Jul 13.
    King's Institute of Therapeutic Endoscopy, King's College Hospital, London, UK.
    Endoscopic submucosal dissection (ESD) enables en bloc resection of large complex colorectal superficial neoplastic lesions, resulting in very low rates of local recurrence, high-quality pathologic specimens for accurate histopathologic diagnosis and potentially curative treatment of early adenocarcinoma without resorting to major surgical resection. The safety and efficacy of the technique, which was pioneered in the upper gastrointestinal tract, has been established by the consistently impressive outcomes from expert centers in Japan and some other eastern countries. However, ESD is challenging to perform in the colorectum and there is a significant risk of complications, particularly in the early stages of the learning curve. Read More

    Splenosis involving the gastric fundus, a rare cause of massive upper gastrointestinal bleeding: a case report and review of the literature.
    Clin Exp Gastroenterol 2016 22;9:301-305. Epub 2016 Sep 22.
    Department of Medicine.
    Splenosis, the autotransplantation of splenic tissue following splenic trauma, is uncommonly clinically significant. Splenosis is typically diagnosed incidentally on imaging or at laparotomy and has been mistakenly attributed to various malignancies and pathological conditions. On the rare occasion when splenosis plays a causative role in a pathological condition, a diagnostic challenge may ensue that can lead to a delay in both diagnosis and treatment. Read More

    Ineffective esophageal motility and the vagus: current challenges and future prospects.
    Clin Exp Gastroenterol 2016 20;9:291-299. Epub 2016 Sep 20.
    Department of Gastroenterology, Renmin Hospital, Wuhan University, Wuhan, People's Republic of China; Division of Gastroenterology, Department of Medicine, Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, ON, Canada.
    Ineffective esophageal motility (IEM) is characterized by low to very low amplitude propulsive contractions in the distal esophagus, hence primarily affecting the smooth muscle part of the esophagus. IEM is often found in patients with dysphagia or heartburn and is commonly associated with gastroesophageal reflux disease. IEM is assumed to be associated with ineffective bolus transport; however, this can be verified using impedance measurements or evaluation of a barium coated marshmallow swallow. Read More

    Self-management in patients with inflammatory bowel disease: strategies, outcomes, and integration into clinical care.
    Clin Exp Gastroenterol 2016 23;9:259-67. Epub 2016 Aug 23.
    Department of Gastroenterology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA.
    Self-management, including medication adherence, is associated with improved health and outcomes for patients with inflammatory bowel disease. The concept of self-management is complex, but can be divided into those aspects that involve the individual patient, those that involve the provider-patient relationship, and those that encompass the social environment. At the individual level, enhancing problem-solving skills and self-efficacy have both been shown to improve self-management tasks, particularly adherence to treatment. Read More

    Acute left-sided colonic diverticulitis: clinical expressions, therapeutic insights, and role of computed tomography.
    Clin Exp Gastroenterol 2016 18;9:249-57. Epub 2016 Aug 18.
    Department of Surgery, Clinique Générale Beaulieu, Geneva, Switzerland.
    The diagnostic approach of patients with suspected acute diverticulitis remains debated. On the one hand, a scoring system with the best predictive value in diagnosing acute diverticulitis has been developed in order to reduce the use of computed tomography (CT) scan, while, on the other hand, patients with a high probability of acute diverticulitis should benefit from CT scan from a clinical viewpoint, ensuring that they will receive the most appropriate treatment. The place and classification of CT scan for acute diverticulitis need to be reassessed. Read More

    Clin Exp Gastroenterol 2016 8;9:237-48. Epub 2016 Aug 8.
    Department of Gastroenterology, Hepatology and Nutrition, University of Minnesota, Minneapolis, MN, USA.
    Despite improvements in medical therapies for Crohn's disease (CD), up to 70% of patients require surgery within 10 years of diagnosis. Surgery is not curative, and almost all patients will experience endoscopic recurrence, and many will go on to clinical recurrence. Identifying patients at high-risk of endoscopic recurrence and standardizing postoperative assessments are essential in preventing clinical recurrence of CD. Read More

    Improving outcomes of refractory celiac disease - current and emerging treatment strategies.
    Clin Exp Gastroenterol 2016 3;9:225-36. Epub 2016 Aug 3.
    Department of Gastroenterology and Clinical Nutrition, Addenbrooke's Hospital, Cambridge, UK.
    Intestinal inflammation and symptoms of celiac disease (CD) usually respond well to gluten withdrawal, but rare cases are refractory to diet. Two types of refractory CD are discriminated on the basis of the presence or absence of an atypical population of mucosal lymphocytes that may progress to enteropathy-associated T-cell lymphoma. Challenges remain in the secure diagnosis of both types of refractory disease, and evidence on which to base treatment recommendations is flawed by the small numbers of reported patients and the use of different diagnostic strategies.

    How do patients' clinical phenotype and the physiological mechanisms of the operations impact the choice of bariatric procedure?
    Clin Exp Gastroenterol 2016 22;9:181-9. Epub 2016 Jul 22.
    Division of Visceral and Transplantation Surgery, University Hospital Zurich (USZ), Zürich, Switzerland.
    Bariatric surgery is currently the most effective option for the treatment of morbid obesity and its associated comorbidities. Recent clinical and experimental findings have challenged the role of mechanical restriction and caloric malabsorption as the main mechanisms for weight loss and health benefits. Instead, other mechanisms including increased levels of satiety gut hormones, altered gut microbiota, changes in bile acid metabolism, and/or energy expenditure have been proposed as explanations for benefits of bariatric surgery.

    Efficacy of the low FODMAP diet for treating irritable bowel syndrome: the evidence to date.
    Clin Exp Gastroenterol 2016 17;9:131-42. Epub 2016 Jun 17.
    Department of Medicine, University of Otago, Christchurch, New Zealand.
    This review summarizes the published clinical studies concerning the management of irritable bowel syndrome (IBS) using restriction of Fermentable Oligosaccharide, Disaccharide, Monosaccharide, and Polyols in the diet (low FODMAP diet). In recent years, the data supporting low FODMAP diet for the management of IBS symptoms have emerged, including several randomized controlled trials, case-control studies, and other observational studies. Unlike most dietary manipulations tried in the past to alleviate gastrointestinal symptoms of IBS, all studies on low FODMAP diet have consistently shown symptomatic benefits in the majority of patients with IBS.

    Ulcerative colitis (UC) is an immune-mediated disease of the colon that is characterized by diffuse and continuous inflammation contiguous from the rectum. Half of UC patients have inflammation limited to the distal colon (proctitis or proctosigmoiditis) that primarily causes symptoms of bloody diarrhea and urgency. Mild-to-moderate distal UC can be effectively treated with topical formulations (rectal suppositories, enemas, or foam) of mesalamine or steroids to reduce mucosal inflammation and alleviate symptoms.

    Peroral cholangioscopy has become an important tool in the diagnosis and treatment of a variety of biliary diseases, ranging from indeterminate biliary strictures to bile duct stones. Although the first cholangioscopy was performed in the 1970s, recent technological advances have provided us with cholangioscopes that yield high-resolution images, possess single-operator capability, and have ultrathin design to allow easier maneuverability and detailed imaging of the biliary tract. We review here the currently available devices for peroral cholangioscopy, their clinical applications, limitations, and complications. Read More

    Essential phospholipids in fatty liver: a scientific update.
    Clin Exp Gastroenterol 2016 5;9:105-17. Epub 2016 May 5.
    VGM Hospital Institute of Gastroenterology, Coimbatore, India.
    Aim: Although essential phospholipids (EPL) from soybean are often used in membrane-associated disorders and diseases, their high quality of purification and effects on prevalent liver diseases, especially on fatty liver diseases (FLDs) of different origin, are still widely unknown and a matter of continuous active research. The aim of this article is to review, discuss, and summarize the available results of EPL in the treatment of FLD.

    Methods: Database research was carried out on Medline, Embase, Cochrane Library, country-specific journals, and follow-up literature citations for relevant hepatogastroenterological articles published between 1988 and 2014. Read More

    Fecal calprotectin: a marker for clinical differentiation of microscopic colitis and irritable bowel syndrome.
    Clin Exp Gastroenterol 2016 21;9:97-103. Epub 2016 Apr 21.
    Department of Gastroenterology, Hepatology and Infectious Diseases, Otto-von-Guericke University, Magdeburg, Germany.
    Background: The aim of this study is to compare two methods for measuring fecal calprotectin (FC) concentration and to evaluate the possibility of differentiation between microscopic colitis (MC) and irritable bowel syndrome (IBS).

    Methods: Twenty-three patients with MC (six patients with active disease and 17 patients retested in remission) and 20 patients with IBS were prospectively included in this study. Active disease state of MC was determined by clinical symptoms of >3 bowel movements per day and histological correlate. Read More
