Background:
Cecal ulcers are sometimes encountered in asymptomatic individuals. Their clinical outcomes and management recommendations remain uncertain.
Methods:
Asymptomatic patients who underwent a colonoscopic exam for colon cancer screening were retrospectively reviewed from July 2009 to November 2016. Patients with cecal ulcers were included. Patients who had colorectal symptoms, such as abdominal pain, had nonsteroidal anti-inflammatory drugs or were lost to follow-up were excluded.
Results:
A total of 34,036 patients underwent colon cancer screening. Cecal ulcers were found in 35 patients. After exclusion, 24 patients (mean duration, 52 months) received follow-up colonoscopy. In 20 patients, (83.3%), cecal ulcer resolved without intervention, but 4 patients (16.7%) developed clinical significant diseases, including intestinal tuberculosis (n = 2), Crohn's disease (n = 1), and ulcerative colitis (n = 1). Patients who developed clinically significant diseases had a higher percentage of ulcers larger than 1 cm (75% vs. 15%, p = 0.035), terminal ileum involvement (100% vs. 15.4%, p = 0.006) and ulcers with irregular fold (75% vs. 5%, p = 0.008).
Conclusions:
In patients with asymptomatic cecal ulcers, the endoscopic features included larger ulcer size, terminal ileum involvement and ulcers with irregular fold may predict development of clinically significant diseases. If the above-mentioned features are present, even asymptomatic patients should be closely monitored.

01:27Inflammatory 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...
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...
