1 위 ESD 후내시경소견 성균관대학교의과대학내과이준행
2 문제의식 위궤양, 조기위암, 진행위암의내시경소견은배운다. 위암수술후소견은가끔배운다. 위암내시경시술후소견은배운적이없다. 관찰과조직검사에대한가이드라인이없다.
3 ESD 후정상내시경소견 성균관대학교의과대학내과이준행
4 처음의뢰되었을때의사진
5 ESD M/D, 18mm, LP, RM (-), L/V (-)
6 추적내시경소견 2 달후 6 달후 3 년후
7 ESD (x2) for EGCs 두달후관찰 2 달후
8 8 주후인공궤양이덜아물기도합니다. - M/74, DM, angina, H/O CVA - M/D, 12mm, MM, 8 주후
9 Converging fold 를만들기도함
10 2017 묘한모양의 scar 도있습니다.
