AIDE: Decision Support for Anastomosis or Colostomy in Emergency Surgery for Complicated Acute Diverticulitis

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.

Characteristics of Abdominal Fluid in Patients With Diverticulitis Hinchey III or IV

Perforated diverticulitis of the colon can be complicated by peritonitis, either purulent or fecal. Both are life threatening conditions requiring emergency surgery. The background in terms of reasons for inflammation (diverticulitis) and perforation to develop is unknown. In this study we focus on specific changes associated with inflammation, both in tissues and of fecal and mucosal microbiota.
