Divertuculosis of a colon - occurrence of diverticulums bind to long rising segmentary pressure in distal departments of a colonic intestine as a result of disturbances of motor function on a background more often age dystrophic changes of connective tissue and muscular elements of an intestinal wall. Stagnation of fecal masses in diverticulums leads to a traumatizing of a mucosa, development of inflammatory process (diverticulitis) extending on a part being by series of a wall of an intestine and on surrounding organs. The diverticulitis can be accompanied by a ulceration of a mucosa (bleeding) or perforation of a diverticulum. Consequence of it can be a peritonitis (local or diffuse), inflammatory infiltrates.

Signs, current. The divertuculosis can longly not have clinical displays or proceed under a kind of a colitis (a unstable feces, a pain on a course of the left half of colon); probably strong bleeding. At an acute diverticulitis the sharp pain, the peritoneal phenomena, morbid infiltrates mainly in the left half of stomach, a fervescence, a cold fit, quite often dysuria (involving of a bladder in an inflammatory infiltrate or formation of an internal fistula owing to perforation of a diverticulum and fusion of a wall of a bladder) are observed.
