Background: Increasing numbers of intestinal carcinomas in patients affected by Crohn's disease have been reported by several authors, even if the strength of this associations (age, longstanding of the disease, its characteristics and distribution) still has to be elucidated.
Methods: From January 1992 to July 2000, 130 patients with Crohn's disease were submitted to surgery.
Results: Four patients showed an associated intestinal carcinoma at operation, in 3 cases located in the ileum, and in 1 case in the colon. Patients' mean age was 54 years. Mean duration time of the Crohn's disease was 7 years. One patient died 3 months after surgery for disseminated peritoneal carcinomatosis, whereas 3 patients are still alive with malignancy free at 5, 8, and 11 years after the tumor resection.
Conclusions: These results suggest the difficulty in recognizing patients with Crohn's disease who are at risk for intestinal carcinoma. Longstanding disease, previous intestinal exclusion surgery, enterocutaneous or other types of fistulas should be considered for the development of cancer. Therefore, the prognosis may be good if early diagnosis and treatment are made.

Servei d'Aparell Digestiu, Hospital Universitari Germans Trias i Pujol (Badalona, Catalonia, Spain).
Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.
Medical, Endoscopic, and Surgical Treatments for Rectal Cuffitis in IBD Patients with an Ileal Pouch-Anal Anastomosis: A Narrative Review.

Department of Gastroenterology, Hepatology, and Nutrition, Cleveland Clinic Foundation, 9500 Euclid Avenue, Cleveland, OH, 44195, USA.
Background: Ulcerative colitis patients who undergo ileal pouch-anal anastomosis (IPAA) without mucosectomy may develop inflammation of the rectal cuff (cuffitis). Treatment of cuffitis typically includes mesalamine suppositories or corticosteroids, but refractory cuffitis may necessitate advanced therapies or procedural interventions. This review aims to summarize the existing literature regarding treatments options for cuffitis.

Sheba Medical Center, Institute of Gastroenterology, Ramat-Gan, Israel.
Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.
Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.
Assessment and Reporting of Extraintestinal Manifestations and Fatigue in Phase 3 Inflammatory Bowel Disease Clinical Trials.
J Crohns Colitis
January 2025
Division of Gastroenterology, Massachusetts General Hospital and Harvard Medical School, Boston, USA.
Background: Extraintestinal Manifestations (EIMs) of Inflammatory Bowel Disease (IBD) are frequently experienced by patients and may lead to severe symptoms and fatigue. However, the reporting patterns of these outcomes in IBD randomized controlled trials (RCTs) is not clear.
Methods: We searched placebo controlled phase 3 RCTs of advanced therapies in IBD and assessed the frequency and means of reporting EIM and fatigue data in these studies.

IRCCS Hospital San Raffaele and University Vita-Salute San Raffaele, Gastroenterology and Endoscopy, Milan, Italy.
Background: Intestinal ultrasound (IUS) is emerging as a valuable tool to assess treatment response in inflammatory bowel disease (IBD) clinical trials. This study details how IUS defines response and remission to evaluate treatment efficacy in IBD patients.
Methods: We conducted a comprehensive search of studies from 1984 to 31 March 2024, focusing on IUS use in assessing treatment efficacy in IBD.
