Abstract
PurposeThe aim of this study was to determine the short- and long-term relative survival as well as the causes of death in patients treated in hospital for acute colonic diverticulitis.Materials and methodsThe study included all patients treated at Levanger Hospital for acute colonic diverticulitis between 1988 and 2012. Vital statistics were complete. The median observation time was 6.95 years (range 0.28–24.66) or until death.ResultsIn total, 650 different patients were hospitalized with acute colonic diverticulitis. Among these patients, there were 851 admissions for the same disease during the 25 years. The admissions had the following diagnoses: simple diverticulitis, 738; abscess formation , 44; perforation and purulent peritonitis, 47; perforation and fecal peritonitis, 9; and intestinal obstruction, 13. During the observation time, 219 were dead and 431 were still alive. After the first admission, the 100 day relative survival in patients with uncomplicated diverticulitis was 97 % (CI 95 to 99), with abscess formation 79 % (62 to 89), with purulent peritonitis 84 % (69 to 92), with fecal peritonitis 44 % (10 to 74), and with intestinal obstruction 80 % (38 to 96). After surviving the first 100 days, the estimated 5-year relative survival in the remaining 609 patients was 96 % (CI 92 to 100) and 10-year survival was 91 % (CI 84 to 97). In patients who survived the first 100 days, the different subtypes of diverticulitis yielded no significant differences in long-term relative survival. All patients who had been admitted with ASA score 4 were dead after 2 years.
Highlights
Acute colonic diverticulitis is an increasingly common acute abdominal condition in the Western world
The objective of the present study was to assess short- and long-term relative survival in patients treated for the different subtypes of acute colonic diverticulitis in hospital
Acute complicated diverticulitis was further classified into four subcategories: abscess formation (Hinchey stage I or II), bowel obstruction related to stenosis, perforation with purulent peritonitis (Hinchey stage III), or fecal peritonitis (Hinchey stage IV) [15]
Summary
Acute colonic diverticulitis is an increasingly common acute abdominal condition in the Western world. Most patients have uncomplicated acute diverticulitis, while 9–35 % develop serious acute complications due to colonic perforation, with abscess formation or diffuse peritonitis, or intestinal obstruction [1,2,3,4,5]. Inhospital mortality has been shown to occur in 0 to 17 % of patients with abscess formation and 0.4 to 45 % of patients with perforation and generalized peritonitis [6,7,8,9,10,11]. Population-based estimates of short- and long-term survival after admission for the different types of acute colonic diverticulitis are scarce. Long-term mortality after different types of diverticulitis has been studied by Binda et al [13] and after perforated
