Diverticulitis, surgery, evidence-based medicine, and the Steve Jobs' dots: a narrative review

Purpose: Emergency treatment of acute diverticulitis remains a hazy field. Despite a number of clinical studies, randomized controlled trials (RCTs), guidelines and surgical societies recommendations, the most critical hot topics have yet to be addressed. Methods: Literature research from 1963 until today was performed. Data regarding the principal RCTs and observational studies were summarized in descriptive tables. In particular we aimed to focus on the following topics: the role of laparoscopy, the acute care setting, the RCTs, guidelines, observational studies and classifications proposed by literature, the problem in case of a pandemic, and the importance of adapting treatment /place/surgeon conditions. Results: In the evaluation of these points we did not try to find any prospective evolution of the concepts achievements. On the contrary we simply report the individuals strands of research from a retrospective point of view, similarly to what Steve Jobes said: "you can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future". We have finally obtained what can be defined "a narrative review of the literature on diverticulitis". Conclusions: Not only evidence-based medicine but also the contextualization, as also the role of 'competent' surgeons, should guide to novel approach in acute diverticulitis management.
