Lens mucous membrane falls inside come off art (ESD) is a when appear in recent years new cure measure. In small achieve a technology to fall, through ESD but complete chunk ground excises pathological changes, at the same time along with all the others " sweeps the pathological changes below mucous membrane of clean " part, implementation effects a radical cure the effect of tumor.
Inchoate cancer of the stomach (EGC) is to show pathological changes of cancer of the stomach is located in mucous membrane or mucous membrane lower level, and whether no matter size of focus of a disease is mixed,lymph node is transferred. Surgical paunch cancer of the stomach effects a radical cure art and lymphatic settle sweep art is a kind of when treat EGC significant step, 5 years survival rate amounts to 96% above. Come off below mucous membrane of the lens inside the EGC that begins in recent years art (ESD) not only remedial effect and surgical laparotomy likeness, and the serious effect of vivid quality of the opposite after the risk that can make major patient absolved conventional surgery to treat again and art.
Surgical cancer of the stomach effects a radical cure art and the first selection that lymph node sweeps art to ever was considered as EGC before are treated, but operation complication occurence rate, mortality is taller, and the life quality after affecting patient art badly. Consider to already confirmed, the EGC with very low occurence rate of lymph node move agrees with inside lens cure.
ESD dominant position is prominent
ESD enlarged what excise below the lens inside EGC to get used to card, reach with laparotomy before EMR inside lens treatment method is compared, ESD has the following and clear advantage:
1, individual turn treatment, specific aim is strong. ESD cure is OK make according to the place of EGC, size, appearance and constituent type reasonable individual change remedial plan, can assure the complete excision of tumor already, can utmost ground retains normal organization and its function.
2, scar is little, the patient is able to bear or endure easily suffer.
3, same patient is acceptability for many times ESD cure, also can undertake much place is treated at the same time.
4, can be in complete constituent pathology sample is not obtained through ESD below the circumstance of the operation, offer tumor to organize credit period accurately, make clear condition of the infiltration deepness of tumor, become divided, whether to exist clearly lymphatic with hemal soak, forecast whether to put in the tall danger element such as lymph node move.
5, compare with EMR photograph, ESD is OK larger area, irregular or configuration is amalgamative the tumour of ulcer, scar is one-time come off thoroughly from surface of inherent flesh layer come down, rate of one-time complete excision achieves 96% above, reduced the remain of tumor and recrudesce apparently.
EGC gets used to card
At present Japan uses ESD to treat EGC to expand get used to card to be:
1, tumor diameter ≤20mm, do not have amalgamative existence ulcer not; of the cancer inside differentiation mucous membrane
2, no matter size of focus of a disease, without; of the cancer inside the become divided of amalgamative existence ulcer mucous membrane
3, tumor diameter ≤30mm, ; of the cancer inside the become divided of amalgamative existence ulcer mucous membrane
4, tumor diameter ≤30mm, mucous membrane of the become divided that does not have amalgamative existence ulcer SM1 issues cancer.
Aged put oneself in another's position is weak, have operation contraindication card or the person that doubt has the cancer below the mucous membrane that lymph node transfers to reject an operation can regard as get used to card relatively
