[Biological criteria of denutrition. Search of significant parameters for diagnosis and management in surgical departments].

Assessment of the nutritional status of surgical patients with a mean weight loss of 11.5 kg included determination of the following biochemical parameters: prealbumin, retinol-binding protein (RBP), serum vitamin A and serum zinc. Patients' immunological status was investigated by delayed hypersensitivity skin tests. Prealbumin and RBP are decreased in patients. RBP levels are significantly lower than in controls: RBP therefore seems to be a better criterion of denutrition than prealbumin. Serum RBP and vitamin A concentrations are not always correlated in patients; for instance, in malabsorptions, the sharp fall in serum vitamin A is isolated. The decrease in mean serum zinc concentrations is minor. Three patients have positive skin tests with severe biochemical disturbances; only serum zinc concentrations are normal and correlated with the results of skin tests. Interpretation of investigations in surgical patients is dependent on the cause of weight loss. However, biochemical and immunological assessment of the nutritional status can demonstrate specific deficits and improve preoperative nutrition.

[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.
