[Traumatic chylothorax. A further indication for total parenteral nutrition]

Successful and rapid resolution of a serious cases of traumatic chylothorax by means of conservative management with TPN is reported. This method is clearly indicated as a mean of making up the calorie and amino acid need when litres of chyle are being lost every day. In addition, by resting the digestive tract it brings about a massive decrease in the production of lymph in the mesenteric district and thus leading to easier and earlier sufficiency of the collateral lymph drainage routes. The rapid decrease in quantity and the change over from chylous to serous chest drainage liquid after TPN are evidence of its soundness. An immediate lymphographic control revealed complete section of the duct. Two months later, collateral diaphragmatic and azygos circulation was observed. It is felt, therefore, that TPN extends the range of conservative management of posttraumatic and postoperative chylothorax.
