{"title":"Pathogenesis of bleeding colonic diverticulosis: new concepts.","authors":"J Baer","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Diverticulosis of the colon is a common disease of the older population which develops in those people who eat highly refined carbohydrate diets free of roughage. High intraluminal pressures are created in the resultant narrowed colon which tends to push the mucosa between circular muscle bundles through oblique connective tissue clefts containing the vasa recta. Massive bleeding of the colon is most commonly due to right-sided diverticulosis. It can be explained by chronic injury to the vasa recta which lie within the submucosa of the diverticulum from the apex to the antimesenteric orifice. Rupture has been documented to occur when the wall of the artery facing the diverticulum becomes weakened by intimal fibrosis, elastic lamina fragmentation, and smooth muscle atrophy. This occurs at the dome and at the antimesenteric orifice of the diverticulum. Selective angiography is the diagnostic tool of choice. Recent advances in pharmacoagiography and and embolization promise successful treatment with lower morbidity than surgical resection.</p>","PeriodicalId":75748,"journal":{"name":"CRC critical reviews in diagnostic imaging","volume":"11 1","pages":"1-20"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11527823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emphasis is on correlation with endoscopy, (twelve color endoscopic photographs are included with the corresponding radiographs illustrating the spectrum of abnormalities in ulcerative and granulomatous colitis), differential diagnosis between ulcerative and granulomatous colitis (the double-contrast technique allows for accurate examination of the rectum and careful mapping of the extent and nature of disease in an involved segment. This facilitates the differential diagnosis between ulcerative and granulomatous colitis), and detection of early changes (in ulcerative colitis, the early stage of mucosal edema results in a finely granular mucosa on double-contrast study. In granulomatous colitis, small, shallow, \"aphthoid\" ulcers are frequently seen as the earliest lesion). The accuracy of the double-contrast technique is assessed by review of series comparing the radiologic and endoscopic findings. This is compared to the accuracy of the conventional enema. Some of the important technical considerations necessary for good double-contrast studies are discussed, as well as some of the potential pitfalls in interpretation.</p>","PeriodicalId":75748,"journal":{"name":"CRC critical reviews in diagnostic imaging","volume":"9 4","pages":"421-47"},"PeriodicalIF":0.0,"publicationDate":"1977-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11542696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
