BACKGROUND AND AIMS: To determine whether spiral computed tomography (SCT) is helpful in the management of adult patients with acute pain of the right lower quadrant. PATIENTS AND METHODS: The prospective study included 204 patients with acute pain of the right lower quadrant during two periods: 104 before and 100 after the introduction of SCT. A questionnaire was completed for each patient before and after standard clinical and laboratory assessment and SCT, indicating the suspected diagnosis and a provisional therapeutic option. RESULTS: In the pre-SCT period the negative laparotomy rate was 29% vs. only 13% in the SCT period. During the SCT period 10 of the 24 nonoperated patients were discharged on the same day, and 14 were hospitalized 1.6+/-1 days, and only one was readmitted for operation on day 7. The accuracy of SCT assisted by results of clinical and laboratory findings (true positives + true negatives/total of patients) was 86% (vs. 73% for standard clinical and laboratory assessment): 93% in men (vs. 76% for standard clinical and laboratory assessment) but only 63% in women (vs. 60% for standard clinical and laboratory assessment). SCT changed the therapeutic decision guided by standard clinical and laboratory assessment in 18 cases, accurately in 16 cases (90%). CONCLUSION: SCT is helpful in the management of adult patients with acute abdominal pain of the right lower quadrant. In our study it reduced negative laparotomy rate from 29% (guided by standard clinicobiological evaluation) to only 13%.
