About

Uncomplicated sigmoid diverticulitis is a common disease in Western countries. Traditional management includes inpatient administration of either oral or intravenous antibiotics with resumption of oral intake as symptoms improve. Recent literature has however questioned both inpatient and antibiotic treatment. Indeed, both inpatient and antibiotic treatment are associated with non-negligible risks to patients. The aim of this trial is to assess the feasibility of a randomized controlled trial designed to determine whether nonantibiotic treatment of uncomplicated diverticulitis is safe in the outpatient setting.

Full description

Uncomplicated sigmoid diverticulitis is a common disease in Western countries. Traditional management includes inpatient administration of either oral or intravenous antibiotics with resumption of oral intake as symptoms improve. Recent literature has however questioned both inpatient and antibiotic treatment. Indeed, both inpatient and antibiotic treatment are associated with non-negligible risks to patients. The aim of this trial is to assess the feasibility of a randomized controlled trial designed to determine whether nonantibiotic treatment of uncomplicated diverticulitis is safe in the outpatient setting. It is designed as a pilot non-inferiority blinded randomized controlled trial. The estimated length of this pilot trial is 1 year. The target population is capable adults of who have a CT-diagnosed episode of uncomplicated diverticulitis who present to the Jewish General Hospital Emergency room.

  2. Suspicion of colorectal cancer on CT scan
