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.

목적 이 연구의 목적은 CT에서 확인된 소장의 작은 상피하종양의 임상 경과를 밝히는 것이다. 대상과 방법 2005년 1월부터 2020년 12월까지 전산화단층촬영에서 소장의 상피하종양이 의심되는 환자들을 분석했다. 최소 2개월 간격을 두고 시행한 2차례 이상 전산화단층촬영에서 30 mm 미만의 소장 상피하종양이 보인 환자를 연구에 포함시켰다. 저자들은 환자의 임상정보, 병변의 소견 및 추적 관찰 영상에서의 변화를 기록하였다. 결과 총 64명의 환자에서 64개의 소장 상피하종양이 분석에 포함되었다. 추적관찰 기간의 중앙값인 15.8개월 동안 병변의 길이 변화와 부피 변화는 각각 0.02 mm/월, 1.5 mm3/월이었다. 소장 상피하종양의 초기 병변의 크기와 크기 변화속도는 통계적으로 유의한 연관성을 보였다. 추가적으로 10 mm 이상의 그룹은 10 mm 미만의 그룹보다 lobulated contour, 불균질한 조영증강, 괴사를 보이는 경우가 더 많았다. 결론 10 mm 미만의 소장 상피하종양이 10 mm 이상 30 mm 미만의 종괴보다 천천히 자란다.
