Objective:
To explore the operative rate and reoperative rate of Crohn disease(CD) in China, and to assess the relative risk factors indicating surgical treatment in CD patients.
Methods:
Data of initial operation and reoperation were evaluated retrospectively in a cohort of 142 patients with CD. The influence of concomitant risk factors was assessed using multivariate analyses.
Results:
Of the 142 cases of CD patients, 64.8% required at least one operation and the cumulative rate of operation was 52% at 5 years after onset. The relative risk of operation was increased in male patients, older than 40 years of age at onset, and those with CD involving small bowel. Of the patients undergone operation, 33.9% relapsed and required reoperation subsequently. The cumulative reoperation rate was 21% at 3 years after first operation. Male gender, a perforating indication for initial operation, as well as colonic and ileocolonic disease, increased the relative risks of reoperation.
Conclusions:
Half of patients with CD will undergo an operation at 5 years after onset, and 20% of them will relapse and require reoperation at 3 years after first operation. Men run a higher risk of operation and reoperation than women do. A perforating indication for initial operation predict a higher risk of reoperation.

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

Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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, 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...
