Background: Symptomatic uncomplicated diverticular disease can affect patients' everyday routine. Considerable efforts have been made to identify clinical features that correlate to the severity of the disease. Unexpected intraoperative abscesses are reported in large retrospective series, showing how uncomplicated symptoms and presentations can underlie a complicated disease. The aim of this study was to investigate the incidence of pericolic or intramural abscess in patients undergoing elective sigmoidectomy for symptomatic uncomplicated diverticular disease and see if chronic symptoms correlate to the presence of an abscess.
Methods: Between January 2016 and June 2018, we prospectively collected data of patients who were given indication to elective sigmoidectomy for symptomatic uncomplicated diverticular disease. Patients were divided into 3 groups: acute resolving, smoldering, and atypical according to a previously described classification of uncomplicated diverticular disease.
Results: One hundred fifty-eight consecutive patients were enrolled in the study. The median age was 63 years (22- 88), and the mean body mass index was 26 (±7) kg/m2. There were 114 patients in the acute resolving group, 36 in the smoldering group, and 8 in the atypical group. An unexpected abscess was reported in 75 patients (47.5%) during surgery or pathological examination. The incidence of -abscess was greater for patient in the smoldering group (p = 0.0243).
Conclusion: Our series of patients affected by symptomatic uncomplicated diverticular disease showed an incidence of unexpected pericolic or intramural abscess of 47.5%. Patients affected by smoldering diverticular disease presented a greater abscess rate.
