Abstract:
A 38-year-old man visited our hospital with a complaint of diarrhea and abdominal pain. Contrast-enhanced computed tomography showed that the ileocecal site was intussuscepted to the transverse colon without ischemia. After we reduced intussusception with an enema using a water-soluble contrast agent, his abdominal pain disappeared. Colonoscopy was performed immediately after reduction and showed erosion and edema at the ileocecal site without tumor. The stool culture at admission revealed verotoxin 1 producing Escherichia coli O-26;therefore, we established a diagnosis of intussusception associated with Escherichia coli enterocolitis. Bacterial enteritis should be considered as a potential cause in adult patients with intussusception.

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...
