Spain282 participantsStarted 2024-11-01

Plain-language summary

The objective of this clinical trial to evaluate the effectiveness and safety of outpatient treatment without antibiotics compared to outpatient treatment with antibiotics in patients with acute uncomplicated diverticulitis. The hypotheses are: * Null Hypothesis (H0): Outpatient treatment without antibiotics in patients with acute uncomplicated diverticulitis is neither safe nor effective and is inferior to outpatient management with antibiotics. * Alternative Hypothesis (H1): Outpatient treatment without antibiotics in patients with acute uncomplicated diverticulitis is safe, effective, and not inferior to outpatient management with antibiotics. We compare the rate of complications, therapeutic failure (clinical worsening and readmission) and recurrence between patients who, on an outpatient basis, are administered antibiotics and those who are not. The patient diagnosed with acute uncomplicated diverticulitis who meets the inclusion criteria is evaluated and examined by a general surgeon. After informing him/her about the pathology, the study will be explained and he/she will be invited to freely participate in it. After accepting and signing the informed consent form, the patient will be included in the study and will be randomly assigned to one of the two treatment arms (outpatient treatment with antibiotics (group A) or without antibiotics (group B).
