Purpose: To determine the frequency and clinical significance of a small amount of isolated pelvic free fluid found at follow-up multidetector-row computed tomography (MDCT) in male patients who have undergone a curative surgery for gastric carcinoma.
Materials and Methods: From January 2005 to June 2010, 1680 male patients were enrolled in this retrospective study that underwent a follow-up MDCT at least 6 months after a curative surgery for gastric carcinoma. The mean follow-up duration was 41 months. The computed tomographic assessment included the detection of ascites, any possible cause, volume and attenuation measurement and the determination of the location.
Results: Of 1680 patients, 83 (4.9%) patients had ascites. Isolated ascites was identified in 66 patients (3.9%). All ascites were located below or at the level of the second sacral vertebral body. The mean volume and mean attenuation of isolated pelvic free fluid were 2.3 ± 1.9 mL and 9.8 ± 4.7 Hounsfield units. During the follow-up period, none of the 66 patients showed signs of peritoneal recurrence.
Conclusion: In 3.9% of male patients, a small amount of isolated pelvic free fluid was detected at the follow-up MDCT after a curative surgery for gastric carcinoma, but without clinical significance.
