Long-term Results of Treatment of Acute Diverticulitis: Still Lessons to Be Learned?

The aim of the present study was to evaluate the long-term results in patients treated for diverticular disease (DD), mainly considering indication for surgery, outcome of the treatment modalities and quality of life. All consecutive patients who underwent treatment for diverticular disease since January 2003 to June 2007 were analyzed. Patients were divided into three groups: medical treatment, elective surgery and emergency surgery. The patients responded to the questions of the Cleveland Global Quality of Life (CGQL) questionnaire and to a symptoms questionnaire during a telephone interview. The long-term outcome parameters such as readmission to the hospital, further surgery for DD, current health status, and quality of life were analyzed according to possible predictors. 146 patients (72.2 %) agreed to submit to the telephone interview and were enrolled in the study. The median follow-up was 99 months. Fifty-two patients were managed with medical therapy, 36 patients received elective operations, and 58 patients underwent acute surgery. Twelve patients (12.7 %) complained episodes of persistent abdominal pain after surgical resection, compared with 6 non-surgical patients (11.5 %). No possible predictors of recurrence, reoperation or readmission were found. The CGQL total scores were found to be similar in the three groups. DD affected bowel function and quality of life of patients in the long-term follow-up regardless of the type of therapy adopted. No long-term advantages of colonic resection were found which should be considered only in patients presenting complicated DD.
