The CDD System in Computed Tomographic Diagnosis of Diverticular Disease

Abstract

Purpose This overview sums up the Classification of Diverticular Disease (CDD) with regard to its application in computed tomographic diagnosis and briefly recapitulates its targeted advantages over preliminary systems. Primarily, application of the CDD in computed tomography diagnostics is described. Differences with respect to the categories of the older systems are pointed out on the level of each CDD type using imaging examples. Materials and Methods The presented images are derived from our institute according to the S2k criteria. Literature was researched on PubMed. Results The CDD constitutes an improvement compared to older systems for categorizing the stages of diverticular disease. It provides more discriminatory power on the descriptive-morphological level and defines as well as differentiates more courses of the disease. Furthermore, the categories translate more directly into state-of-the-art decision-making concerning hospitalization and therapy. Conclusion The CDD should be applied routinely in the computed tomographic diagnosis of diverticular disease. Typical imaging patterns are presented. Key points  The CDD is superior to its predecessors. It better stratifies categories of diverticular disease by morphology, course and modern options for treatment of the disease. Computed tomography is the dominant imaging modality. Different stages show typical imaging patterns. Non-abscessed phlegmonous peridiverticulitis is now interpreted as an uncomplicated course. Minimal paracolic air does not constitute a full-fledged perforation in terms of a pneumoperitoneum (CDD type 2c). Citation Format Pustelnik D, Elsholtz FH, Bojarski C et al.
