To assess the value of ultrasound as an initial diagnostic method in cases of acute diverticulitis. Garcia-Aguayo, F J Gil, P M [Hospital de Sagunto. (Author) 14 refsĪcute diverticulitis of the sigmoid colon: value of ultrasound as an initial diagnostic test Diverticulitis aguad de sigma: valor de la ecografia como test diagnostico inicialĮnergy Technology Data Exchange (ETDEWEB) CT should be performed when ultrasound fails to provide a diagnosis or in cases of negative results when there is a strong clinical suspicion of diverticulitis, as well as when the possibility of complicated diverticulitis exists. Ultrasound is a valid test in the initial diagnosis of acute diverticulitis of the sigmoid colon. CT provided the correct diagnosis in eight of these cases, and resulted in false negatives in two cases of mild diverticulitis. Of the 10 false negatives on ultrasound, seven corresponded to cases of simple diverticulitis and three to cases of complicated diverticulitis (two in patients with abscess and one in a patient with pneumoperitoneum). The sensitivities of ultrasound and CT were 81% and 94%, respectively, and their specificities were 79% and 83%, respectively. The final diagnosis was acute diverticulitis in 52 patients, some other disease in 18 and undetermined in 6. The CT diagnosis was based on two indispensable findings: thickening of the sigmoid colon of>4 mm and inflammation of pericolonic fat. The diagnostic criteria established for ultrasound was a thickening of the sigmoid colon wall of >4 mm and the presence of a least one of the following features: diverticular, phlegmon or abscess. The final diagnosis was based on the clinical course in every case, as well as on computed tomography (CT n=46), histopathological examination (n=10), colonoscopy (n=4) and barium enema (n=2). ![]() (orig.)Īcute diverticulitis of the sigmoid colon: value of ultrasound as an initial diagnostic test Laparoscopy is probably the most accurate method in diagnosing diverticulitis. CT can be recommended as the first examination in seriously ill patients where abscesses and other causes of the symptoms than diverticulitis must first be rule out. Conclusion: CT was the best method for diagnosing abdominal pathology outside the colon. CT had a high specificity (1.0 95% CI: 0.92-1.0) but low sensitivity (0.69 95% CI: 0.56-0.79) in detecting diverticulitis. Laparoscopy proved to be superior to the other diagnostic methods in diagnosing diverticulitis of the sigmoid colon. Results: Fity-two patients were found to have sigmoid diverticulitis: 20 patients by lanparoscopy, 21 by CT, and 11 by CE combined with one positive laboratory test. Material and Methods: The diagnostic methods were prospectively evaluated in 88 patients, 30 of whom were referred for laparoscopy. Purpose: To evaluate the use of laparoscopy, CT, colonic enema (CE), and laboratory tests (white blood cell count (WBC), sedimentation rate (SR), and C-reactive protein (CRP)) in diagnosing diverticulitis of the sigmoid colon.
