[Clinikomorphological features of complicated colon diverticulosis].

79 surgical and postmortem cases of colon diverticulosis with complications were studied clinicomorphologically. Sequence in the development of inflammatory complications was revealed: diverticulum perforation-peridiverticulitis-pericolitic infiltrate, sometimes with the abscess-fistula. Segmental colitis may join the process. The complications onset depends mainly on discoordination of the intestinal peristalsis and intramural vascular deficiency.
