수술 전 내시경 검사에서 암이 하나였는데, 수술 후 최종 병리에서 암이 두개로 보고되는 예가 있습니다. 첫 내시경 사진을 잘 살펴보아도 두번째 병소를 찾지 못하는 경우가 대부분입니다.
최종 병리 결과를 옮깁니다.
1-3. Stomach, subtotal gastrectomy:
. Multiple gastric carcinomas (x2)

【GROSS DESCRIPTION 】
1. FS-1
Received fresh labeled "proximal margin" is a mucosal strip, measuring 1cm.
Entirely embedded.
2. FS-2
Received fresh labeled "distal margin" is a mucosal strip, measuring 1cm.
Entirely embedded.
3.
Received fresh is a subtotally resected stomach with the omentum in continuity. The stomach is previously opened along the greater curvature by the surgeon and measures 16.5 cm along the greater curvature and 10 cm along the lesser curvature. The serosal surface is smooth and glistening. The mucosal surface shows a depressed lesion (EGC type IIc), measuring 1x0.6 cm, at the lesser curvature of body. The lesion is located 2.2 cm apart from the proximal resection margin and 6.5 cm apart from the distal resection margin. All perigastric lymph nodes found are embedded.
