ABSTRACT
OBJECTIVES: Obliteration with cauterization of the internal opening of pyriform sinus fistulas, with or without marsupialization, has been a mainstay for preventing recurrence. However, this procedure predisposes patients to recurrence caused by the reopening of the cauterized orifice. We applied suture ligation to secure the closure of the internal orifice f ollowing cauterization and evaluated treatment.
METHODS: A total of 42 patients were diagnosed with third or fourth branchial cleft anomaly with internal pyriform sinus fistula and treated either with cauterization or with cauterization and suture ligation, between January 2008 and December 2020. The medical records were reviewed to assess demographic characteristics, clinical presentations, diagnoses, surgical treatment, and outcomes. Treatment flow characteristics for intractable patients were analyzed.
RESULTS: The median age of onset was 9 years (range, 0-57 years). Neck swelling (n = 32, 76.2%) was commonly encountered symptom, and a history of neck infection was found in 27 patients (64.3%). After initial treatment, 11 cases (56.2%) recurred. Younger age (≤9 years) and thyroid involvement were associated with recurrence (P = .034 and P = .046, respectively). Cauterization with suture ligation presented lower recurrence rate (19.2%) than cauterizatio n only (37.5%, P = .037). Cauterization with suture ligation for recurrent cases (n = 11) showed 81.8% (9/11) of cure rate. Intractable fistulas (n = 2) from both groups were also salvaged by suture ligation.
CONCLUSIONS: Suture ligation with cauterization for an internal orifice of branchial anomaly showed lower recurrence rate than cauterization only. This method was beneficial for refractory cases.
