1. Delayed bleeding after gastric ESD

화요일에 시술하고 토요일에 출혈한 환자입니다 (4일째 출혈). 토혈이나 검은 변이 있으면 인근 병원 방문을 권했습니다. 인근 의료기관을 방문하였는데 조처가 다소 미흡하지 않았나 생각됩니다. 다행스럽게 환자 상태는 stable 했습니다. 앞으로 좀 더 자세히 설명드려야겠다는 생각을 하였습니다.


2. Adenoma with HGD

72세 여성 검진 내시경


ESD: Tubular adenoma with high grade dysplasia:
1) size: 1.8x1.2 cm
2) gross type: flat
3) negative resection margins


3. Metachronous gastric cancer (deep SM invasion, lymphatic positive)

과거 조기위암 내시경치료를 받은 여성입니다. 치료부에 가깝지만 다소 떨어진 위치 이소성 위암이 발견되어 ESD를 하였는데 수술이 필요한 결과가 나왔습니다.


Stomach, endoscopic submucosal dissection:
Early gastric carcinoma
1. Location : mid antrum
2. Gross type : EGC type IIc
3. Histologic type : tubular adenocarcinoma, moderately differentiated
4. Histologic type by Lauren : intestinal
5. Size of carcinoma : (1) longest diameter, 13 mm (2) vertical diameter, 12 mm
6. Depth of invasion : invades submucosa, (depth of sm invasion : 1000 ㎛) (pT1b)
7. Resection margin : involved deep resection margin by carcinoma with cauterized artifacts safety margin : distal 15 mm, proximal 13 mm, anterior 16 mm, posterior 14 mm, deep 0 mm (sm only)
8. Lymphatic invasion : present (+++)
9. Venous invasion : suspicious
10. Perineural invasion : not identified(N)
11. Microscopic ulcer : absent
12. Histologic heterogeneity: absent


4. Early gastric cancer


Stomach, subtotal gastrectomy:
Early gastric carcinoma
1. Location : middle third, Center at body and posterior wall
2. Gross type : EGC type IIc
3. Histologic type : tubular adenocarcinoma, poorly differentiated
4. Histologic type by Lauren : intestinal
5. Size : 3x1.5 cm
6. Depth of invasion : invades mucosa (muscularis mucosa) (pT1a)
7. Resection margin: free from carcinoma
8. Lymph node metastasis : no metastasis in 37 regional lymph nodes (pN0)
9. Lymphatic invasion : not identified
10. Venous invasion : not identified
11. Perineural invasion : not identified
12. Peritoneal cytology : negative


5. Early colon cancer

검진 대장내시경에서 발견된 병소로 ESD를 시행하였습니다.


Ascending colon, endoscopic submucosal dissection:
Adenocarcinoma, well differentiated :
1) size of carcinoma: (1) longest diameter, 12 mm (2) vertical diameter, 7 mm
2) invasion into submucosa: present (depth of submucosal invasion: 2200 ㎛)
3) lymphovascular invasion: not identified(N)
4) perineural invasion: not identified(N)
5) tumor budding: not identified(N)
6) resection margins: free from carcinoma(N) (0.02 cm apart from deep resection margin)

Deep SM invasion으로 right hemocolectomy 시행하였고 no residual tumor가 나왔습니다.
