Colonic Diverticula Clinical Trial
Official title:
Predictive Value of the Diverticular Inflammation and Complication Assessment (DICA) Endoscopic Classification on the Outcome of the Diverticular Disease of the Colon: a Prospective, Multicenter, International Study.
The Diverticular Inflammation and Complication Assessment (DICA) is an endoscopic classification for diverticulosis and diverticular disease of the colon. The aim of the study is to show that DICA classification is a valid parameter to predict the risk of acute diverticulitis occurrence/recurrence and the need of surgery in patients suffering from diverticulosis/diverticular disease of the colon.
The Diverticular Inflammation and Complication Assessment (DICA) endoscopic classification has been recently developed for patients suffering from diverticulosis and diverticular disease. A recent multicentre, international, retrospective study found that DICA classification has a significant predictive value on the outcome of the disease in terms of acute diverticulitis occurrence/recurrence and surgery occurrence. The aim of the present study is to confirm the above mentioned results propectively Several centers, worldwide distributed, will be involved. A minimum of 281 patients will be required for the study. This calculation will be based on the assumption that a continuity-corrected chi-square test with a type I error of 0.05 and a type II error of 0.20 will be expected to detect a difference between a 4.3% prevalence of diverticulitis in patients with diverticulosis and 8.6% in DICA I patients. Only patients at the first endoscopic diagnosis of diverticulosis/diverticular disease will be enrolled. For each patient, we recorded: age; severity of DICA score; severity of symptoms at entry and during the follow-up; C-reactive protein (CRP) and fecal calprotectin test at the time of diagnosis and during the follow-up (CRP only for DICA 2 and 3 patients); comorbidities (if any); concomitant therapies (if any); therapy taken during the follow-up to maintain remission (if any); months of follow-up; occurrence/recurrence of acute diverticulitis; need of surgery. The study will take three year. The investigators aim at confirming that DICA classification is a valid parameter to predict the risk of acute diverticulitis occurrence/recurrence and the need of surgery in patients suffering from diverticulosis/diverticular disease of the colon. This could permit to select populations at higher or lower risk, having or not benefit from scheduled (and type) treatment able to reduce those risks. ;
