Primary Outcome Measures :
  1. Gastrointestinal quality of life-index change at 6 months [ Time Frame: 6 months from randomization ]
    Difference in gastrointestinal quality of life-index (GIQLI) at randomization and 6 months from randomization.


Secondary Outcome Measures :
  1. GIQLI at 12, 24, 48, and 96 months [ Time Frame: 12, 24, 48, and 96 months from randomization ]
  2. Short form (SF) 36 Health survey score at 6, 12, 24, 48, and 96 months [ Time Frame: 6, 12, 24, 48, and 96 months from randomization ]
  3. Recurrence and severity of recurrent diverticulitis [ Time Frame: 0 - 96 months from randomization ]
  4. Need of emergency surgery due to diverticulitis [ Time Frame: 0 - 96 months from randomization ]
    Whether or not patient has undergone emergency surgery due to diverticulitis during follow-up period. Assessment will be carried out by patient questionnaire and search for patient records.

  5. Need of elective sigmoid resection due to diverticulitis (conservative arm) [ Time Frame: 0 - 96 months from randomization ]
    Whether or not patient has undergone elective sigmoid resection due to diverticulitis during follow-up period. Assessment will be carried out by patient questionnaire and search for patient records.

  6. Complications due to elective sigmoid resection [ Time Frame: 0 - 96 months from randomization ]
  7. Mortality [ Time Frame: 0 - 96 months ]
  8. Complications of diverticular disease [ Time Frame: 0 - 96 months ]
  9. Stoma rate [ Time Frame: 0 - 96 months from randomization ]
