[Preoperative renutrition in patients with esophageal stenosis].
50 patients suffering from dysphagia and oesophageal stenosis were treated in the period 1975-77. Of these 31 had renutrition of longer than two weeks and are the subject of the present study. Three nutrition systems were employed: 1) total parenteral feeding (7 patients), 2) feeding by naso-gastric tube or gastric fistula (15 patients), 3) feeding per os with semiliquid foods (9 patients). The patients were suffering from benign cicatricial stenosis (5), tumours of the cardia (7), tumours of the oesophagus (19). Short-term survival, weight behaviour and the course of certain blood parameters (Hb, GR, cholesterol, albumin, total proteins) are reported.


CONCLUSIONS
--in benign cicatricial stenosis and tumours of the cardia, a normal protein-caloric amount (2000-3500 KCal., 80-120 g/24 h of proteins) is sufficient to obtain weight increase and stabilization of blood examinations. The administration route is unimportant; --in malignant stenosis, 4000-6000 KCal. and 100-130 g of protein/24 h must be provided to obtain the same result. In patients treated with total parenteral nutrition the weight loss persists. The reason for this behaviour is not known; it is likely that enzymatic blocks exist in substrate utilization; --further study is needed to improve results obtained and to clarify the reasons for such behaviour.
