[Current resources of microsurgery for the re placement of the cervical oesophagus and the hypopharynx (author's transl)].

A technique of oesophago-jejunostomy in the neck is described using an isoperistaltic jejunal Y loop with added vascularisation from the internal mammary vessels via microsurgical anastomoses. This technique is used either for solely palliative purposes when the tumour is inoperable, or after oesophagectomy as a method of reconstruction of the digestive tract. An experimental study in the dog of replacement of the cervical oesophagus using a free gastric, jejunal or colonic transplant indicates the possibility of envisaging these techniques in the near future in man after circular total pharyngo-laryngectomy. The importance of these modern technique made possible by microsurgery is of two types: --value in adequate treatment of the tumour, since the resection can be extensive, the length of the graft being such that the whole of the oesophagus can be replaced; --functional value since the result is immediate and of good quality.
