A localized sac-like barium-filled protruding shadow of the ascending colon, about 5.5 mm in diameter, with thinning of the terminal ileocecal lumen and poor dilatation should be considered as a problem of intestinal diverticula. In general, if the intestinal diverticulum does not affect the normal function of the intestine, it is not considered a serious problem. Intestinal diverticulum refers to the phenomenon that the mucosa of localized intestinal tissues is relatively thin and expands outward during imaging. There are two types of diverticula: congenital and acquired. Congenital diverticula are mostly caused by structural variations of the colon, which usually do not cause any disease, and the intestinal function is normal. Acquired mostly due to surgery and late improper care, if there is no infection and other manifestations, the condition is not serious; but if repeated infections, affecting the normal function of the intestinal tract, prone to cause inflammation, and even diverticular hemorrhage, perforation of the situation. At this time, the condition is serious and requires active intervention and treatment.
