- W2064274003 abstract "BACKGROUND: Following the nonoperative management of acute diverticulitis, guidelines recommend routine follow-up colonoscopy; however, evidence to support this recommendation are lacking. OBJECTIVE: This study aims to determine the diagnostic yield of endoscopy for clinically significant neoplasia following the successful nonoperative management of acute diverticulitis. DESIGN: This study is a retrospective review. SETTING: This study was conducted in a large urban health region. PATIENTS: Adult patients who were admitted with a diagnosis of acute diverticulitis confirmed by CT and who were successfully managed nonoperatively to hospital discharge were included. Patients who underwent colonoscopy within 2 years of presentation were excluded. MAIN OUTCOME MEASURE: The primary outcome measured was the incidence of clinically significant neoplasia (invasive malignancy or advanced adenoma) on follow-up endoscopy within 1 year of admission. RESULTS: Four hundred fifty-eight patients were selected for analysis, of which 249 patients (54%) underwent endoscopy within 1 year of admission. Seventy-seven (30.9%) patients were found to have polyps, 19 (7.6%) patients had advanced adenomas, and 4 (1.6%) patients had an invasive malignancy; 23 patients (9.2%) were found to have clinically significant neoplasia. On subgroup analysis, patients presenting with complicated diverticulitis (n = 74) had a significantly higher incidence of advanced adenoma (18.9% vs 5%, p = 0.001) and invasive malignancy (5.4% vs 0%, p = 0.007) in comparison with patients who presented with uncomplicated diverticulitis (n = 175). On multivariate analysis, patient age (OR 1.04 (1.01–1.08), p = 0.02) and the presence of abscess (OR 4.15 (1.68–10.3), p = 0.002) were identified as significant risk factors for clinically significant neoplasia. LIMITATIONS: The use of retrospective data was a limitation of this study; 54% of selected patients underwent endoscopic follow-up. CONCLUSIONS: The incidence of clinically significant neoplasia on endoscopic follow-up after the nonoperative management of acute diverticulitis is 9.2%. Those with complicated diverticulitis are at higher risk, whereas the incidence of clinically significant neoplasia in those with uncomplicated diverticulitis is equal to the incidence in average-risk individuals. Routine diagnostic colonoscopy following the nonoperative management of acute uncomplicated diverticulitis may not be warranted." @default.
