Diverticulosis
Diverticulosis of the digestive tract refers to local cystic bulges in the digestive tract, which are of two types: true and false. The former refers to full-thickness bulges, while the latter refers to only mucosa and submucosa without muscular bulges. Most diverticula bulge out of the digestive tract cavity, and very few bulge into the cavity, which are called intracavitary diverticula. The presence of multiple diverticula at the same time is called diverticulosis. This disease is seen in the entire digestive tract, with the colon being the most common, followed by the duodenum, and gastric diverticula being the least common. Diverticulosis with symptoms or complications is called symptomatic diverticula or diverticular disease, which requires treatment.
