Acute Diverticulitis

A single-center, prospective observational cohort study conducted at the University Hospital of Navarra. The primary objective is to expand knowledge of diverticular disease and its pathological variants, as well as the influence of the microbiota in our environment, both clinically and molecularly; to describe the clinical and pathological characteristics of patients with diverticulosis and acute diverticulitis; to analyze any differences in the microbiota; and to identify the risk factors and groups associated with diverticular disease in order to establish the best strategies for prevention and treatment.

The AIDE/OBS study is a multicenter, observational, non-interventional study designed to collect standardized clinical, radiological, intraoperative visual, and surgical reasoning data from adult patients undergoing non-elective surgery for complicated acute diverticulitis. The study focuses on patients requiring urgent or emergency operative management, including cases following failure of non-operative management. The main intraoperative decision of interest is the choice between sigmoid resection with primary anastomosis, with or without diverting stoma, and Hartmann's procedure. The current phase aims to build a structured multimodal dataset and to validate and refine a preliminary expert-informed decision-support tool. The study does not modify standard clinical practice, surgical indication, operative strategy, or postoperative management. All treatment decisions remain at the discretion of the treating surgical team according to local practice.

In Europe, patients with acute left colon diverticulitis (ALCD) are usually admitted to surgical wards even when only medical treatment is required. The study compares ALCD non-operative management (NOM) between surgical and non-surgical environments regarding clinical outcomes, hospitalization length(LOS), and follow-up.

The WIRES-T project (Web-based International Registry of Emergency General Surgery and Trauma) has been set up to allow to all the EGS (Emergency General Surgery) and Trauma surgeons to register their activity and to obtain a worldwide register of traumatic and non traumatic surgical emergencies. This will give the opportunity to evaluate results on a macro-data basis and to give index allowing stratifying, evaluating and improving the outcomes.
