Postoperative chylous fistula prevention and management
The Laryngoscope
|June 1, 1976
Summary
Postoperative chylous fistulas complicate 1-2% of radical neck dissections. Early recognition and treatment, including surgical ligation for persistent cases, improve outcomes for this rare complication.
Area of Science:
- Surgical Oncology
- Thoracic Surgery
Background:
- Radical neck dissection (RND) is a critical surgical procedure for head and neck cancers.
- Postoperative chylous fistulas (PCFs) are a known complication, occurring in 1-2% of RND procedures.
Observation:
- This review examines twelve cases of PCFs following RND.
- While PCFs are more frequent after left-sided dissections, 25% of cases in this series occurred on the right.
- Intraoperative identification and management of chylous fistulas were achieved in 75% of patients who subsequently developed postoperative fistulas.
Findings:
- PCFs can be categorized into minor and major types based on severity.
- Minor fistulas may resolve with conservative measures like pressure dressings and aspirations.
- Major fistulas, unresponsive to conservative treatment, necessitate early re-exploration and ligation.
Implications:
- Prompt diagnosis and appropriate management are crucial for PCF resolution.
- Surgical ligation remains a definitive treatment for refractory chylous fistulas.
- Understanding the laterality and intraoperative recognition rates can inform surgical planning and vigilance.
