Acquired jejunal and ileal diverticulosis (Meckel excluded).

Acquired jejuno-ileal diverticulosis are rare (0,1 to 1,4%) but their compl ications are non exceptionals (6 to 13%) with a death rate which can reach 40% in older patients. From a histological view, acquired diverticulosis di ffer from congenital ones by an absent muscular tunic. Complications consis t in, by descending order : diverticulitis, perforation (7%), acute bowel o bstruction (3%), intestinal hemorrhage (2,7%) mostly massive, malabsorption of fat, protein, macrocytic anaemia, intestinal tumors same as found in sm all bowel. The treatment of small bowel diverticulosis becomes surgical onl y when complicated. It consists in the strict resection of the complicated diverticulosis area, respecting the asymptomatic diverticulosis. Prophylaxi s of the complications is based on healthy diet habits against stasis, bowe l pressure using antispasmodics, intestinal desinfectants, residue free die t, and against infection (oral tetracyclins).
