Management of lymphatic fistulas by total parenteral nutrition.

Lymphatic fistula is a rare surgical complication, which mainly occurs after cervical or retroperitoneal lymph node dissection and which frequently requires a surgical repair. A small series of nine postoperative lymphatic fistulas treated conservatively with total parenteral nutrition (TPN) is reported. All the patients were malnourished at the beginning of the TPN, and all exhibited an objective improvement of their nutritional status after completion of the treatment. Due to the interruption of the enteral alimentation or to the nutritional repletion, spontaneous closure of the fistula was achieved in eight of nine patients treated with TPN longer than 1 week. The authors conclude that whenever the immediate surgical repair is not recommended, or it is not successful, a 2- to 3-week course of TPN may be used with the chance of spontaneous healing. In any case, patients conservatively treated by TPN can undergo a delayed operation with minimal risk because of the improved nutritional status.
