Objectives
Narrative objectives1 In traditional Japanese herbal (Kampo) medicine, daiobotanpito (DBT) or Da Huang Mu Dan Tang in Chinese has been used in medical treatment of acute diverticulitis for many years based on the experience. Our former study investigated the treatment of acute diverticulitis can be treated with intravenous antibiotics plus orally administrated DBT than intravenous antibiotics alone. A retrospective non-randomized open-label trial was established to compare patients with acute diverticulitis who received oral DBT associated with intravenous antibiotics with those who received intravenous antibiotic alone. There was a significantly better outcome in the group treated with DBT than in the group without DBT when comparing duration of fever, abdominal pain, and antibiotics administration. A trend toward a day shorter mean hospital stay and fasting was seen in group 1, although this did not reach statistical significance. From this result, we assumed that most patients with acute diverticulitis can be managed safely with oral DBT. In this study, randomized, double-blind study will be done to show the possibility to use daiobotanpito as additional option in treating acute diverticulitis.

Pericolonic abscess, free air or extravasation, and accumulation of fluid will also be assessed to predict prognosis.

2. Patients considered highly likely to exhibit abscess perforation due to malnutrition, serum Albumin less than 2.5
3. Patients with symptoms of obstructive ileus
4. Patients who exhibit chronic anorexia, abdominal pain, and/or diarrhea symptoms before the onset of colorectal diverticulitis
5. Before the onset of colorectal diverticulitis, performance status, an indicator of general condition and the degree of restriction of the patient's daily life, of more than three
