Inflammatory bowel disease (IBD) with/without complications

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic condition characterized by inflammation of the gastrointestinal tract, leading to symptoms such as abdominal pain, diarrhea (sometimes bloody), weight loss, and fatigue. CD can affect any part of the digestive system, while UC primarily involves the colon and rectum. The exact cause remains unclear, but genetic, immune, and environmental factors play a role. Complications may include strictures (narrowing of the intestine), fistulas (abnormal connections between organs), abscesses, and an increased risk of colorectal cancer.

Small intestinal tumors or polyps

Small intestinal tumors and polyps are relatively rare but potentially serious growths that develop in the small intestine, which connects the stomach to the colon. While many small intestinal polyps are benign (non-cancerous), some may have malignant potential or indicate an increased risk of developing cancer over time. Common symptoms include abdominal pain, chronic diarrhea, unexplained weight loss, anemia (due to hidden blood loss), or intestinal obstruction, though many small intestinal lesions remain asymptomatic until they grow large enough to cause complications. Diagnosis typically involves capsule endoscopy, double-balloon enteroscopy (DBE), or cross-sectional imaging like CT or MRI enterography to locate and characterize the lesions.
