ELEMENTAL DIET IN GASTROINTESTINAL SURGERY

The concept of enteral hyperalimentation with elemental diet was introduced with the background of the manifest results of total parenteral nutrition. We have recently developed a new product of ED which is modified after Vivonex-HN. All elemental components of ED are very easely soluble in water and absorbed from upper small intestine. With 50 cm loop of jejunum (Thiry-Vella loop) in our mongrels experiment, crystalline L-amino acids are absorbed totaly by 77%. Clinical route of the continous administration of ED is by nasoduodenal feeding with ED catheter which is deviced for this purpose especially for preoperative patients. Gastrostomy and needle catheter jejunostomy are used as the route of ED after surgery. Above 80% of our cases of enteral hyperalimentation are given more than 2400 kcal a day with 2% of diarrhea. Intensive nutritional care with ED is well indicated especially for the patients of esophageal carcinoma in pre-and postoperative periods. The effects of ED in the treatment of anastomotic leakage and fistula were almost same as that of TPN. ED is bulkfree and faecal bulk is decreases by the administration of ED, so it is well indicated for the bowel preparation and postoperative care of colon surgery.
