This is the second of a series of two articles reporting the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of adult patients with ulcerative colitis [UC]. The first article is focused on medical management, and the present article addresses medical treatment of acute severe ulcerative colitis [ASUC] and surgical management of medically refractory UC patients, including preoperative optimisation, surgical strategies, and technical issues. The article provides advice for a variety of common clinical and surgical conditions...

BACKGROUND & AIMS: Coffee is associated with a reduced risk of liver disease. This association is limited by important sources of confounding such as recall bias, healthy user bias, and indirect measures of liver outcomes or health. We aimed to examine the impact of coffee consumption with liver fibrosis and steatosis in a nationally representative sample. METHODS: We evaluated 4510 subjects 20 years and older from the 2017 to 2018 National Health and Nutrition Examination Survey study who underwent both transient elastography and two 24-hour dietary recall examinations...

INTRODUCTION: "Push" or "pull" techniques with the use of snares, forceps, baskets, and grasping devices are conventionally used to manage esophageal food bolus impaction (FBI). A novel cap-assisted technique has recently been advocated to reduce time taken for food bolus (FB) removal. This study aimed to compare the effectiveness of the cap-assisted technique against conventional methods of esophageal FB removal in a randomized controlled trial. METHODS: Consecutive patients with esophageal FBI requiring endoscopic removal, from 3 Australian tertiary hospitals between 2017 and 2019, were randomized to either the cap-assisted technique or the conventional technique...

Inflammatory bowel disease is a chronic disease with variable degrees of extent, severity, and activity. A proportion of patients will have disease that is refractory to licensed therapies, resulting in significant impairment in quality of life. The treatment of these patients involves a systematic approach by the entire multidisciplinary team, with particular consideration given to medical options including unlicensed therapies, surgical interventions, and dietetic and psychological support. The purpose of this review is to guide clinicians through this process and provide an accurate summary of the available evidence for different strategies...

BACKGROUND & AIMS: We evaluated treatment withdrawal, long-term outcomes, and safety of budesonide oral suspension (BOS) 2.0 mg twice daily in patients with eosinophilic esophagitis who completed a 12-week induction study. METHODS: Induction full responders (≤6 eosinophils per high-power field [eos/hpf] and ≥30% reduction in the Dysphagia Symptom Questionnaire score) to BOS 2.0 mg twice daily (ORBIT1/SHP621-301/NCT02605837) were randomized to continue BOS (BOS-BOS) or withdraw to placebo (BOS-PBO) for 36 weeks (ORBIT2/SHP621-302/NCT02736409)...

BACKGROUND & AIMS: Despite rescue therapy, more than 30% of patients with acute severe ulcerative colitis (ASUC) require colectomy. Tofacitinib is a rapidly acting Janus kinase inhibitor with proven efficacy in ulcerative colitis. Tofacitinib may provide additional means for preventing colectomy in patients with ASUC. METHODS: A retrospective case-control study was performed evaluating the efficacy of tofacitinib induction in biologic-experienced patients admitted with ASUC requiring intravenous corticosteroids...

Inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis, are chronic, progressive, immune-mediated diseases of adults and children that have no cure. IBD can cause significant morbidity and lead to complications such as strictures, fistulas, infections, and cancer. In children, IBD can also result in growth impairment and pubertal delays. IBD is highly heterogenous, with severity ranging from mild to severe and symptoms ranging from mild to debilitating. Delay in IBD diagnosis, especially in Crohn's disease, is common and associated with adverse outcomes...

BACKGROUND & AIMS: Comparative effectiveness has become increasingly important to help position therapies for inflammatory bowel disease. We compared the efficacy and rapidity of onset of action of infliximab vs ustekinumab induction therapy for moderate to severe biologic-naïve Crohn's disease (CD) using patient-level data from randomized controlled trials. METHODS: This was a post hoc analysis of 2 large CD clinical trial programs that included data on 420 biologic-naïve CD patients...

BACKGROUND & AIMS: The adenoma detection rate (ADR) and characteristics of previously resected adenomas are associated with colorectal cancer (CRC) incidence and mortality. However, the combined effect of both factors on CRC mortality is unknown. PATIENTS AND METHODS: Using data of the Austrian quality assurance program for screening colonoscopy, we evaluated the combined effect of ADR and lesion characteristics on subsequent risk for CRC mortality. We analyzed mortality rates for individuals with low-risk adenomas (1-2 adenomas <10 mm), individuals with high-risk adenomas (advanced adenomas or ≥3 adenomas), and after negative colonoscopy (negative colonoscopy or small hyperplastic polyps) performed by endoscopists with an ADR <25% compared with ≥25%...

BACKGROUND & AIMS: The purpose of this expert review is to describe the current methodologies available to manage malignant alimentary tract obstructions as well the evidence behind the various methods (including their efficacy and safety), indications, and appropriate timing of interventions. METHODS: This is not a formal systematic review but is based on a review of the literature to provide best practice advice statements. No formal rating of the quality of evidence or strength of recommendation is carried out...

Patients with postoperative Crohn's disease are difficult to manage because of their risk of experiencing a more severe course, multiple symptom confounders, and poor sensitivity of symptomatic remission to rule out intestinal inflammation. In this group, data are lacking on biologic therapeutic efficacy, and recommendations are lacking for those with multiple medication failures. Novel noninvasive testing can simultaneously exclude alternate causes of symptoms (serum C4, fecal fat, small intestinal bowel overgrowth breath testing) and assess intestinal inflammation (fecal calprotectin, endoscopic healing index)...

DESCRIPTION: Endoscopic techniques are paramount in the identification and management of complications after surgery, though collaboration with other specialties is obligatory. Unfortunately, the evaluation and treatment algorithms are not standardized and there is a paucity of high-quality prospective studies to provide clarity regarding the best approach. The purpose of this clinical practice update is to apprise the clinician with respect to the endoscopic evaluation and management of patients with early (<90 days) complications after undergoing bariatric/metabolic surgery...

BACKGROUND: Infection and increased systemic inflammation cause organ dysfunction and death in patients with decompensated cirrhosis. Preclinical studies provide support for an antiinflammatory role of albumin, but confirmatory large-scale clinical trials are lacking. Whether targeting a serum albumin level of 30 g per liter or greater in these patients with repeated daily infusions of 20% human albumin solution, as compared with standard care, would reduce the incidences of infection, kidney dysfunction, and death is unknown...

Colorectal cancer (CRC) is the third most common cancer in men and women in the United States. CRC screening efforts are directed toward removal of adenomas and sessile serrated lesions and detection of early-stage CRC. The purpose of this article is to update the 2009 American College of Gastroenterology CRC screening guidelines. The guideline is framed around several key questions. We conducted a comprehensive literature search to include studies through October 2020. The inclusion criteria were studies of any design with men and women age 40 years and older...

INTRODUCTION: Microscopic colitis is a chronic inflammatory bowel disease characterised by normal or almost normal endoscopic appearance of the colon, chronic watery, nonbloody diarrhoea and distinct histological abnormalities, which identify three histological subtypes, the collagenous colitis, the lymphocytic colitis and the incomplete microscopic colitis. With ongoing uncertainties and new developments in the clinical management of microscopic colitis, there is a need for evidence-based guidelines to improve the medical care of patients suffering from this disorder...

BACKGROUND & AIMS: Adenoma detection rate (ADR) is a key measure of colonoscopy quality. However, efficient measurement of ADR can be challenging because many colonoscopies are performed for non-screening purposes. Measuring ADR without being restricted to screening indication may likely facilitate more widespread implementation of quality monitoring. We hypothesized that the ADR for all colonoscopies, irrespective of the indication, would be equivalent to the ADR for screening colonoscopies...

INTRODUCTION: Current guidelines recommend anticoagulation as the mainstay of portal vein thrombosis (PVT) treatment in cirrhosis. However, because of the heterogeneity of PVT, anticoagulation alone does not always achieve satisfactory results. This study aimed to prospectively evaluate an individualized management algorithm using a wait-and-see strategy (i.e., no treatment), anticoagulation, and transjugular intrahepatic portosystemic shunt (TIPS) to treat PVT in cirrhosis. METHODS: Between February 2014 and June 2018, 396 consecutive patients with cirrhosis with nonmalignant PVT were prospectively included in a tertiary care center, of which 48 patients (12...
