Abstract
Introduction: One of the most frequent and troublesome complication following laryngectomy is pharyngocutaneous fistula (PCF). There are a lot of different risk factors for PCF suspected and evaluated, but only few proven.
Objective: Evaluation the role of different pharynx closure techniques on PCF-incidence.
Material and method: The charts of 92 patients, treated for carcinoma of the larynx with laryngectomy at MBAL “Sv. Marina” between july 2007 and december 2014 (86 males, 6 females, aged 61.9 +/- 8.2 years; T4=39, T3=53; N0=71 and N+ =21) were evaluated retrospectively. Three types of closure of the neohypopharynx were used: linear plasty in 31 cases, Y-shaped plasty in 46 cases and atypical type of closure with local tissues being stretched beyond the midline in the remaining 6 cases (called ZZ, TL or L). The primary endpoint was development of clinically evident PCF. The analysis was performed via Student’s t-test.
Results: The overall incidence of PCF was 7.53%. 1/46 (2.17%) in the Y-plasty group, 3/31 (9.68%) in the I-plasty group and 1/6 (16.67%) in the atypical plasty group developed PCF. The statistical result of the analysis does not find significance in the development of PCF between the groups.
Conclusion: The type of the suture line for closure of the neohypopharynx in previously unirradiated patients with otherwise uniform surgical technique does not appear to be a risk factor for PCF.
