Abstract
The conventional “mixer diets” for tube feeding, might have caused the higher incidences of diarrhea in consequence of retardation of recovery in the subjects received surgery against alimentary tracts. In the present studies clinical significances in post-surgical nutrition of asceptic liquid formulae 51-a (A) and 52-a (A) were examined by means of tube feeding to those subjects who were in nursed period subsequent to alimentary surgery. The formula 51-a (A) was characterized by containing the protein and the carbohydrate hydrolysates, while 52-a (A) was derived from 51-a (A) including reduction of the protein concentration and adjustment of balance in essential amino acids in order to prevent from diarrhea and to lower the functional load against alimentary organs which possessed lesions due to surgical treatment.
The results were described below.
1. Incidences of diarrhea in subjects who received surgery against their alimentary tracts and then subsequently fed 51-a (A) and 52-a (A) were remarkably reduced in comparison with those control subjects who fed the “mixer diet”
2. Incidences of diarrhea in subjects, fed the control “mixer diet” subsequent to the surgery, varied dependent upon the species of the alimentary organs which were subjected to operations and the incidences of diarrhea increased to the order of the cases of operations against cancer of head and neck and esophagal carcinoma. The formulae 51-a (A) and 52-a (A) resembled to the control mixer diet in the aspect that the incidences were increased to the order of those cases against cancer of head and neck, esophagal carcinoma and total gastrectomy when fed the subjects with the formulae.
3. Tentative nutritional values of the formulae, as expressed by profiles of the quantitative analysis of the serum protein, were assessed.
The significant restoration in the profile in subjects, received surgical operations and then fed 51-a (A) and 52-a (A) to a comparable doses, were observed while the restoration was only limited in those fed the control mixer diet even to higher doses which exceeded by 64% over the case of feeding of 52-a (A).
