Postoperative chylous fistula prevention and management

Abstract

Postoperative chylous fistulas occur as a complication in 1-2% of all radical neck dissections. Twelve cases are reviewed herein. Chylous fistulas are more common with left neck dissections, but 25% occurred on the right side in this series. An intraoperative chylous fistula was recognized and treated in 75% of the cases which later developed a postoperative fistula. Postoperative fistulas may be divided into two groups: minor fistulas may be treated with pressure dressings and repeated aspirations; fistulas which do not respond to conservative management should be re-explored early and the fistula ligated.
