L’échoendoscopie par mini-sonde de haute fréquence est-elle nécessaire avant une mucosectomie endoscopique?
Is Echoendoscopy with high frequency mini probes necessary before endoscopic mucosectomy?
The development of the techniques of endoscopic treatment of superficial cancers of the digestive tract (endoscopic mucosectomy) requires before starting a loco-regional assessment (parietal and lymph nodes) as precise as possible. Indeed, the endoscopie mucosectomy (ME) can apply only to tumours with a low risk of lymph node invasion, but this risk is quite related to the local infiltration of the lesion and only the lesions limited to the mucous membrane or to the first third of the submucosa (sml) will be treated by EMR. The question is to know whether echoendoscopy (EUS) can visualize an infiltration of the submucosa (i.e. crossing the muscularis mucosae) in a reliable way. In addition, the place of EE is to be modulated according to the organ concerned (oesophagus, stomach, colon and rectum).
