Objectives:
To evaluate the influence of the indication of the first surgical procedure on the prognosis of Crohn's disease.
Methods:
We compared retrospectively the long-term course of 179 patients operated on for a perforating disease and 322 patients operated on for a nonperforating disease. Mean follow-up was 11 years and 2 months in the two groups.
Results:
Forty of 179 (25%) and 106 of 322 (33%) patients with perforating and nonperforating diseases underwent a second intestinal resection, respectively. The patients who had been operated on for a perforating disease were significantly more often reoperated on for the same indication, and conversely. Patients with perforating diseases experienced less second resections (actuarial rates: 37 +/- 11% vs 51 +/- 8% at ten years respectively), less post-surgical handicaps (mean index 24.9 vs 27.9), and fewer patients required immunosuppressive drugs (25 vs 35%).
Conclusion:
Long-term prognosis of perforating Crohn's disease does not appear to be more severe than that of nonperforating disease.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory Bowel Disease I: Ulcerative Colitis
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...
Inflammatory 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
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
