Abstract:
A 60-year-old man visited our department because of watery diarrhea that lasted for several months. On colonoscopy, we diagnosed him as ulcerative colitis. Additionally, a laterally spreading tumor (non-granular type) was discovered in the rectum above the peritoneal reflection (Ra). The patient was initially treated with 5-aminosalicylic acid. Four months later, endoscopic submucosal dissection was performed. Histopathology examination showed a sporadic tubular adenoma. Complete en bloc resection was performed.

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...

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
