It is well established that the nutritional state greatly influences tolerance during the operation. Authors present a new procedure for the early postoperative enteral alimentation having not been used in Hungary so far. Twelve hours after operation, a pump-operated, gradually increasing amount of oligopeptide food-preparation and concentrate is introduced continuously into the second jejunal loop intraoperatively. Using this method, a caloric intake of 9572 kJ can be achieved already from the fourth postoperative day onwards. Based on our experience gained from 32 patients, the method can be recommended for an up-to-date postoperative enteral alimentation.
