Acute Diverticulitis and Advanced Colonic Neoplasia. When to Perform Colonoscopy (ADACOLON Study)
Acute Diverticulitis and Advanced Colonic Neoplasia. When to Perform Colonoscopy (ADACOLON Study)
This study evaluate the prevalence of advanced colonic neoplasia (ACN) in acute
 diverticulitis. A sub-analysis of complicated and uncomplicated acute diverticulitis will be
 made in order to determinate whether there are differences of advanced colonic neoplasia
 (ANC) prevalence in both groups and to assess if a colonoscopy is necessary.
This is a prospective study that eliminates biases in the selection, design and variability
 of retrospective studies to reliably assess the global prevalence of advanced colon neoplasia
 (ACN) and the difference in prevalence among populations with complicated and uncomplicated
 acute diverticulitis diagnosed by computed tomography. Another objective is to assess the
 diagnostic prediction of computed tomography to detect ACN in acute diverticulitis. It also
 aims to assess the safety and quality of colonoscopy in a patient recently diagnosed with
 acute diverticulitis. Finally, it aims to study whether other diagnostic tools such as the
 presence of clinical risk symptoms or the performance of fecal biological tests could help in
 narrowing the indication of colonoscopy in this clinical scenario.
Inclusion Criteria:

 All patients consecutively diagnosed with acute diverticulitis in the participating
 hospitals during the study inclusion period will be included. For this purpose, a
 multidetector computerized tomography confirming the diagnosis of acute diverticulitis must
 be performed on all patients with initial clinical suspicion.

 Exclusion Criteria:

 1. Patient refusal to participate in the study.

 2. Impossibility of obtaining informed consent by the patient or guardian.

 3. Age <18 years and> 85 years

 4. Impossibility of performing a diagnostic CT of AD.

 5. Intercurrent medical or surgical process with prolonged recovery in time that prevents
 a colonoscopy before 6 months after the resolution of the episode of acute
 diverticulitis.
