Introduction: Anal fistula in Crohn's disease is frequently an intractable condition. Methods of treatment are still debated because the results of various procedures are unsatisfactory. Available studies show that results can be improved using a combination of surgical and medical methods. Most patients undergo rather palliative than radical, curative procedures such as incision and drainage of abscesses and prolonged non-cutting seton placement. Surgery is combined today with biological therapy using infliximab, a murine-human chimeric monoclonal antibody against TNF-α or adalimumab a human monoclonal anti-TNF antibody to increase the healing process and in an attempt to prevent fistula recurrence.
Methods: Medical records of 23 patients who were treated for anal fistulas in Crohn's disease between 2012 and 2014 were retrospectively evaluated.
Results: There were 10 (43%) males and 13 females. The mean age was 39 years (range 29-60 years). Median duration of CD before present treatment was 6 years (range 1-15 years). Closure of all fistulas in 6 months was achieved in eight (35%) patients, whereas reduction of at least 50% from base line in the number of draining fistulas occurred in four (17%) patients.
Conclusion: Palliative and combined therapy for anal fistulas in Crohn's disease with surgery and infliximab or adalimumab therapy is an effective treatment for some patients.

The CT findings of extranodal natural killer/T-cell lymphoma, nasal type involving the gastrointestinal tract.
Eur Radiol
January 2025
Department of Radiology, The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
Objectives: To analyze the CT imaging features of extranodal natural killer/T (NK/T)-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI), and to compare them with those of Crohn's disease (CD) and diffuse large B-cell lymphoma (DLBCL).
Materials And Methods: Data were retrospectively collected from 17 patients diagnosed with GI ENKTCL-NT, 68 patients with CD, and 47 patients with DLBCL. The CT findings of ENKTCL-NT were analyzed and compared with those of CD and DLBCL.
Comparative Improvement in Health-Related Quality of Life with Advanced Therapies for Moderate-to-Severe Crohn's Disease: A Network Meta-Analysis.
Am J Gastroenterol
January 2025
Zane Cohen Centre for Digestive Diseases, Lunenfeld-Tanenbaum Research Institute, Sinai Health System, Toronto, Ontario, Canada.
Background And Aims: The comparative efficacy of advanced therapies to improve health-related quality of life (HR-QoL) in Crohn's disease (CD) is unknown. We aimed to compare the impact of approved advanced therapies for moderate-to-severe CD on HR-QoL.
Methods: We searched MEDLINE, Embase, and Cochrane CENTRAL from inception to December 2023.
The Role of Environmental Factors Prior to Diagnosis on the Activity and Severity of Inflammatory Bowel Diseases-Results From the Prospective Population-Based Copenhagen Inflammatory Bowel Disease Inception Cohort.
United European Gastroenterol J
January 2025
Department of Gastroenterology and Hepatology, Copenhagen University Hospital - Herlev and Gentofte, Herlev, Denmark.
Background: The influence of environmental factors on the severity of early inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is unclear. Herein, we aimed to investigate the role of environmental factors in the initial phenotype, activity, and severity of IBD.
Methods: Copenhagen IBD Inception Cohort is a prospective population-based cohort of patients with newly diagnosed IBD between May 2021 and May 2023.

Department of Internal Medicine, Section of Gastroenterology, Esbjerg Hospital - University Hospital of Southern Denmark, Esbjerg, Denmark.
Background And Aims: Prior studies indicate that serum calprotectin (SC) and plasma calprotectin (PC) can be used as biomarkers in Crohn's disease (CD). The aim of this study was to investigate the diagnostic accuracy of SC and PC in patients with a clinical suspicion of CD.
Method: This biobank study included patients from a prospective, blinded, multicenter study examining minimally invasive modalities for diagnosing CD.
