Symptomatic uncomplicated diverticular disease: a critical appraisal.

Introduction: Symptomatic uncomplicated diverticular disease (SUDD) is a clinical condition included in the spectrum of symptomatic diverticular disease. The symptom profile associated with SUDD is highly heterogeneous, as there are currently discordant definitions, that encompass many clinical scenarios.

Areas covered: We conducted a narrative review to assess the symptom profile and diagnostic criteria of SUDD based on the available evidence. A thorough literature search was performed on PubMed following the SANRA scale. Abdominal pain, regardless of its duration and location, emerges as the cardinal symptom of SUDD, suggesting that it should be central to its diagnosis. Although abdominal bloating and changes in bowel habits are commonly reported, they do not appear to be specifically attributable to SUDD. Other issues considered are the possible overlap with irritable bowel syndrome and the identification of a subcategory of SUDD patients with chronic symptoms following an episode of acute diverticulitis.

Expert opinion: The future agenda should include the development of shared diagnostic criteria for SUDD, including well-defined inclusion and exclusion clinical features and symptom patterns.
