Early or delayed sigmoid resection in complicated diverticular disease? A single center experience

Abstract Background:Diverticular disease appears to be one of the most common conditions in the western world. The standard approach in treatment of diverticular disease is a laparoscopic resection, usually after an inflammation free time of 4 to 6 weeks. The aim of this study was to evaluate the timing of operation. Methods: 61 patients underwent left-sided colonic resection because of diverticular disease between January 2017 and February 2020. 37 patients were treated because of complicated diverticulitis (CDD stage 2a or 2b) either early within 7 days after first symptoms (group A: n = 17) or delayed about 6 weeks after the first contact and conservative therapy (group B: n = 20). Results: Overall mortality was 0%. The average operation time was shorter in the early elective group (Group A: 140,4 min vs. Group B: 151,2 min (p = 0,29). The hospital stay (group A: 9,9 d vs. group B: 16,9 d) and the postoperative stay (group A: 4,8 d vs. group B: 8,1 d) was significantly longer in group B (p = 0,01). We observed – although not reliable due to low number of patients - more postoperative complications in the delayed group (group A: 5,9% vs. group B: 15,0%) (p = 0,61). Conclusion: The data in this study confirm the early operation as safe and efficient due to lower costs. We can recommend an early approach in selected cases with the first episode of a complicated diverticulitis.
