Background: The efficacy of Pseudomonas aeruginosa-mannose sensitive hemagglutinin (PA-MSHA) injection therapy in the treatment of chyle fistula following neck dissection is unclear.
Methods: This prospective study enrolled 26 patients who developed chyle fistula after neck dissection. Patients were divided into high-output (>500 mL) and low-output groups (≤500 mL) and were initially treated conservatively for 5 days in the high-output group or 7 days in the low-output group. When conservative treatment failed, topical PA-MSHA therapy was applied.
Results: Twelve of 26 patients were cured with conservative treatment, and the remaining 14 patients were all successfully resolved by PA-MSHA therapy. Chyle fistula got resolved in the low-output and high-output groups after the initiation of therapy were at a median 1 days and 6 days, respectively. Among them, 12 (85.7%) patients experienced fever and 11 (78.6%) patients experienced neck pain.
Conclusions: Topical PA-MSHA injection therapy could effectively manage chyle fistula following neck dissection.
