Classification of Acute Diverticulitis for Stage-directed Therapy

Abstract

In recent years, there has been a significant change in the treatment recommendations for acute diverticulitis. In order to provide the right treatment to the individual patient, it is therefore important to classify the stage of the disease accurately, after taking various aspects into consideration. Patients treated for acute diverticulitis in Würzburg University Hospital during 2010 to 2014 were included. Inclusion criteria were the presence of a computer tomography for disease classification. More than half of the patients examined (n = 135, 52.9%) had acute uncomplicated diverticulitis on admission; 112 (43.2%) had a covered perforation (small paracolic abscess n = 63, 24,3%; large abscess n = 49, 18,9%) and 12 (4.6%) a free perforation. In a total of 150 (57.9%) patients, this was the first episode of diverticulitis, with a covered (66.1%) or a free perforation (75.0%) occurring at a higher than average rate as the first manifestation. Nearly two-thirds (66.4%, n = 168) of patients underwent sigmoid resection during follow-up. Despite current trends towards more conservative therapy of acute diverticulitis, sigmoid resection remains a corner stone of successful therapy throughout all types of acute diverticulitis. The indication of sigmoid resection nowadays requires profound knowledge of the individual prognosis for recurrent diverticulitis and quality of life.
