Bolkenstein HE, et al. – Risk factors that could predict complicated diverticulitis were identified in this meta–analysis. This study identified several risk factors correlated with complicated diverticulitis although high–level evidence was lacking. Independently, in predicting the course of diverticulitis, these risk factors had little value. The authors proposed a prognostic model combining these risk factors which could be the next step to aid the physician in predicting the course of diverticulitis and setting the right treatment at initial presentation.
