Secondary Tracheoesophageal Puncture After Laryngectomy Increases Complications With Shunt and Voice Prosthesis

Objectives/Hypothesis To evaluate the demographics, clinical features, management, and prognostic indicators of tracheoesophageal puncture complications in patients undergoing placement of voice prosthesis following cancer treatment. Study Design Retrospective analysis. Methods A retrospective analysis was conducted of cases from a tertiary referral center diagnosed between 1996 and 2015. Multivariate logistic regression was used to determine factors associated with tracheoesophageal puncture (TEP) and voice prostheses–complication‐free survival (TEP/VP‐CFS). Results One hundred fourteen cases were identified. Most patients were males (92.9%) with pT3 (26.8%) or pT4 (58.1%) N+ (53.6%) tumors. All patients received laryngectomy as the primary treatment, with 75% of patients receiving adjuvant radiation therapy or chemoradiotherapy. Complications with TEP were common (65.2%). The most frequent problem was salivary leakage (50.0%), which at the same time was the most common reason for changing the prosthesis. On univariate regression analysis, prosthesis placement time after adjuvant radiotherapy (hazard ratio [HR]: 4.17, 95% confidence interval [CI]: 2‐8.69), secondary prosthesis placement after primary surgery (HR: 3.97, 95% CI: 1.99‐7.9), and laryngectomy with flap reconstruction (HR: 1.96, 95% CI: 0.99‐3.89) were significant prognosticators for complications. Multivariate regression analysis revealed secondary prosthesis placement after adjuvant radiotherapy (HR: 3.66, 95% CI: 1.39‐9.68) or after primary surgery (HR: 2.57, 95% CI: 0.92‐7.2) to be the strongest predictors of reduced TEP/VP‐CFS. Conclusions Secondary prosthesis placement after primary surgery, placement after previous irradiation, and laryngectomy with flap reconstruction are predictors of poor TEP/VP‐CFS. Planned adjuvant radiotherapy is not a contraindication for TEP with prosthetic placement, but it is very important to place the prosthesis during the primary surgery or at least before scheduled radiotherapy.
