    Abstract Perianal fistulizing Crohn's disease represents a severe phenotype associated with significant morbidity. Patients with perianal fistulizing disease are more likely to have a severe disease course and have significant reductions in quality of life. Moreover, these patients are at risk for the development of distal rectal and anal cancers. Given the complexity and severity of this patient group, the management of perianal Crohn's disease must be undertaken by a multidisciplinary team. The gastroenterologist and colorectal surgeon play a critical role in the diagnosis and management of perianal fistulizing disease. An examination under anesthesia provides critical information and is an essential part of the work-up of complex perianal fistulas. The radiologist also plays a central role in characterizing anatomy and assessing response to treatment. Several imaging modalities are available for these patients with magnetic resonance imaging as the imaging modality of choice. Perianal disease developing after ileal pouch-anal anastomosis represents a particularly challenging form of fistulizing disease and requires a multidisciplinary clinical and radiologic approach to differentiate surgical complications from recurrent Crohn's disease.

    Abstract Background: Hidradenitis suppurativa (HS) is associated with inflammatory bowel disease (IBD), though risk factors remain to be determined.
    Aim: To characterize HS among a cohort of IBD patients and identify risk factors for its development.
    Methods: This was a retrospective case-control study at the ambulatory IBD centre at Mount Sinai Hospital from inception to May 2019. Patients with IBD who developed HS were included. Cases were matched 5:1 by age, gender (male versus female) and IBD type (ulcerative colitis [UC] or Crohn's disease [CD]) to controls who had IBD without HS. Conditional logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (95% CIs).
    Results: Twenty-nine cases of HS (19 CD and 10 UC) and 145 controls were included. Of the 29 patients with HS, 11 (37.9%) were male and 18 (62.1%) were female. The severity of HS was mild in 10 (34.5%), moderate in 16 (55.2%) and severe in 3 (10.3%) patients. Patients with HS and IBD were more likely to be active (OR 10.3, 95% CI 2.0 to 54.0,
    Conclusions: Active IBD, perianal disease and smoking may be associated with HS in IBD. Larger studies are needed to better characterize this morbid condition.

    Abstract Systemic vasculitides are caused by inflammation of blood vessels and can affect any organ and any part of the gastrointestinal tract, hepatic and biliary system, as well as the pancreas. These disorders can cause a wide array of gastrointestinal manifestations, from asymptomatic elevated transaminase levels and mild abdominal pain to potentially life-threatening bowel perforations and peritonitis. A diagnosis based solely on gastrointestinal symptoms is challenging as these manifestations are not specific. Conversely, diagnostic and therapeutic delays can be rapidly detrimental. In this article, we review the epidemiology, characteristics and management of the main gastrointestinal manifestations of systemic vasculitides, including polyarteritis nodosa and antineutrophil cytoplasm antibody-associated vasculitides, as well as isolated vasculitides limited to the gastrointestinal tract.

    Abstract Patients with inflammatory bowel disease are at an increased risk for the development of colorectal cancer. However, the magnitude of this risk may not be as high as earlier studies have suggested. This shift in risk may be a result of changes in quality of analyses, aging cohorts, or may indeed represent true declines in the risk of cancer as a result of improvements in medical therapy and surveillance programs. The best surveillance practices for colorectal cancer screening in patients with inflammatory bowel disease remains unclear. The finding of dysplasia on colonoscopy in these patients warrants multi-disciplinary consultation between endoscopist, pathologist, and patient. At present, major organizations offer guidelines for surveillance interval, as well as when surgical consultation is advised. Moreover, newer endoscopic technologies have been developed and their incorporation into dysplasia surveillance programs continues to evolve.

    Abstract Background & aims: We aimed to compare the effectiveness of single- vs multiple-strain probiotics in a network meta-analysis of randomized trials.
    Methods: We searched MEDLINE, Embase, Science Citation Index Expanded, CINAHL, Scopus, Cochrane CENTRAL, BIOSIS Previews, and Google Scholar through January 1, 2019, for studies of single-strain and multistrain probiotic formulations on the outcomes of preterm, low-birth-weight neonates. We used a frequentist approach for network meta-analysis and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the certainty of evidence. Primary outcomes included all-cause mortality, severe necrotizing enterocolitis (NEC) (Bell stage II or more), and culture-proven sepsis.
    Results: We analyzed data from 63 trials involving 15,712 preterm infants. Compared with placebo, a combination of 1 or more Lactobacillus species (spp) and 1 or more Bifidobacterium spp was the only intervention with moderate- or high-quality evidence of reduced all-cause mortality (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.39-0.80). Among interventions with moderate- or high-quality evidence for efficacy compared with placebo, combinations of 1 or more Lactobacillus spp and 1 or more Bifidobacterium spp, Bifidobacterium animalis subspecies lactis, Lactobacillus reuteri, or Lactobacillus rhamnosus significantly reduced severe NEC (OR, 0.35 [95% CI, 0.20-0.59]; OR, 0.31 [95% CI, 0.13-0.74]; OR, 0.55 [95% CI, 0.34-0.91]; and OR, 0.44 [95% CI, 0.21-0.90], respectively). There was moderate- or high-quality evidence that combinations of 1 or more Lactobacillus spp and 1 or more Bifidobacterium spp and Saccharomyces boulardii reduced the number of days to reach full feeding (mean reduction of 3.30 days [95% CI, reduction of 5.91-0.69 days]). There was moderate- or high-quality evidence that, compared with placebo, the single-species product B animalis subsp lactis or L reuteri significantly reduced duration of hospitalization (mean reduction of 13.00 days [95% CI, reduction of 22.71-3.29 days] and mean reduction of 7.89 days [95% CI, reduction of 11.60-4.17 days], respectively).
    Conclusions: In a systematic review and network meta-analysis of studies to determine the effects of single-strain and multistrain probiotic formulations on outcomes of preterm, low-birth-weight neonates, we found moderate to high evidence for the superiority of combinations of 1 or more Lactobacillus spp and 1 or more Bifidobacterium spp vs single- and other multiple-strain probiotic treatments. The combinations of Bacillus spp and Enterococcus spp, and 1 or more Bifidobacterium spp and Streptococcus salivarius subsp thermophilus, might produce the largest reduction in NEC development. Further trials are needed.

    Abstract Hospitalized patients with inflammatory bowel disease (IBD) are at high risk for morbidity, mortality, and health care utilization costs. While the literature on trends in hospitalization rates for this disease is conflicting, there does appear to be significant variation in the delivery of care to this complex group, which may be a marker of suboptimal quality of care. There is a need for improvement in identifying patients at risk for hospitalization in an effort to reduce admissions. Moreover, appropriate screening for a number of hospital acquired complications such as venous thromboembolism and Clostridium difficile infection is suboptimal. This review discusses areas of inpatient care for IBD patients that are in need of improvement and outlines a number of potential quality improvement initiatives such as pay-for-performance models, quality improvement frameworks, and healthcare information technology.
