[Prevention and management of chylous fistula after neck dissection].

OBJECTIVE
To evaluate the effect of treatment for chylous fistulas after neck dissection, as a means of reasonable option of therapeutic measures.


METHODS
Of 37 chylous fistulas, 30 were left-sided and 7 were right-sided. Conservative therapy which included closed-wound drainage and local pressure dressing and/or low-fat nutritional support was employed in 26 cases, and 50% glucose was injected into the neck basic wound bed in 2 cases, to promoto the chylous fistula healing up. Operative ligation was performed in 7 cases. Open-wound and packing in 4 cases.


RESULTS
Eighty-six percent chylous fistula occured from 1 to 3 postoperative days. Of 26 chylous fistulas with conservative management, 15 cases were successfully treated, the mean duration for healing was 9.7 (4-30) days, the remaining 11 cases failed to had and were further treated surgically. Seven cases with operative ligation were successful, and the other 4 cases with open-wound and packing had delayed healing, the mean duration was 8.5 (7-10) days.


CONCLUSION
The majority of patients with chylous fistulas could be treated reasonablly without increasing the hospital days. The conservative therapy should be employed in cases with a maximal production of chyle below 500 ml a day. Operative ligation should be done early in cases with a maximal production exceeding 500 ml a day and with conservative treatment failure for a few days. The open-wound and packing should be used in chylous fistulas persisting for more then 7 days.
