Abstract:
Purpose:This study aimed to evaluate the natural growth of subepithelial tumors of the small bowel detected on CT.
Materials and Methods:Consecutive patients who were suspected of having subepithelial tumors of the small bowel between January 2005 and December 2020 were reviewed. Eligible patients with suspected small (< 30 mm) subepithelial tumors on at least two CT evaluations were included in the analysis. The patients’ data on demographic characteristics, tumoral characteristics, and tumoral size changes during the follow-up were collected.
Results:This study included 64 patients with suspected small subepithelial tumors (n = 64) of the small bowel. After a median follow-up of 15.8 months, the diameter and volume growth rates were 0.02 mm/month and 1.5 mm3/month, respectively. A significant correlation was observed between the initial size and the growth rate of the small bowel subepithelial tumors. The group of large-sized tumors (initial diameter ≥ 10 mm) tended to show lobulated contours, heterogeneous enhancement, and necrotic changes more frequently than the group of small-sized tumors (initial diameter < 10 mm).
Conclusion:Small bowel subepithelial tumors measuring less than 10 mm grew more slowly than those measuring 10–30 mm.
