Background:
Isolated small bowel Crohn's disease (ISBCD) is often associated with poorer clinical outcomes. This study aims to summarize the clinical characteristics of patients with ISBCD and to investigate the risk factors for surgical recurrence due to disease recurrence.
Methods:
A retrospective study was conducted using a prospective database of Crohn's patients. Patients with ISBCD were screened and divided into stricturing and nonstricturing groups according to the Montreal classification behavior definition. The primary endpoint was reoperation due to postoperative recurrence of Crohn's disease. Other endpoints included intraoperative and postoperative outcomes, as well as clinical characteristics. Multivariable Cox regression analysis was used to assess the independent risk factors for surgical recurrence.
Results:
From January 2017 to June 2024, totally 234 patients (135 in the stricturing group) were included. After propensity score matching, with 79 patients in each group. During the follow-up period (1-90 months), surgical recurrence rates were significantly higher in the stricturing group (11%) compared to the nonstricturing group (4%) (P = 0.04), this was confirmed in Kaplan-Meier curve with log-rank analysis (P = 0.04). No significant differences were observed in postoperative outcomes between the two groups. Variables with P < 0.1 in univariable analysis (stricturing behavior, smoking history, hypoalbuminemia, escalation, or conversion of biologic during follow-up) were incorporated into the multivariable Cox regression analysis, which demonstrated the stricturing behavior [hazard ratio (HR) 4.010; 95% confidence interval (CI) 1.024-15.704; P = 0.04] and the escalation or conversion of biologic agents (HR 6.453; 95% CI 1.906-21.844; P < 0.01) postoperatively were independent risk factors for surgical recurrence.
Conclusion:
The stricturing phenotype is associate with increased risk of operative surgical recurrence in patients with ISBCD. These patients should have a more active prophylactic strategy for the prevention of recurrence after surgery.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
