General understanding Diverticular disease (diverticulosis) of the colon represents morpho-functional pathological process, characteristic feature of which is the presence of saccular protrusions of the colon wall (Diverticula) Diverticular disease - a disease characterized by clinical manifestations of varying degrees of severity due to the presence of a diverticulum or diverticulosis, including inflammation (diverticulitis) and its complications (peridiverticulitis, abscess, perforation, fistula, peritonitis) Diverticulum - a protrusion of the colon wall. True diverticulum contain all layers of the colon wall. False diverticulum (pseudodiverticulum) represent the protrusion of mucous membrane through gaps in the muscular layer of the colon. Example of true diverticulum is the congenital diverticulum (Meckel's diverticulum), and the false diverticulum are the acquired diverticulum of the colon. Diverticulosis - presence of multiple...
