Abstract

Objective

The purpose of this study was to systematically evaluate the risk factors of pharyngocutaneous fistula (PCF) after total laryngectomy.

Methods

We systematically searched Pubmed, Web of Science, Cochrane Library, and Embase databases and included the literature according to the inclusion and exclusion criteria.

Results

A total of 52 studies with 8605 patients were included in the meta-analysis. The total incidence of PCF was 21% (1808/8605). Meta-analysis results indicated that age (OR = 1.29, 95% CI 1.06–1.58, P = 0.01), smoking (OR = 1.62, 95% CI 1.27–2.07, P < 0.01), COPD (chronic obstructive pulmonary disease) (OR = 1.62, 95% CI 1.19–2.22, P < 0.01), CAD (coronary atherosclerotic heart disease) (OR = 1.82, 95% CI 1.36–2.45, P < 0.01), T-stage (OR = 0.81, 95% CI 0.67–0.98, P = 0.03), previous radiotherapy (OR = 2.41, 95% CI 2.00–2.90, P < 0.01), preoperative albumin (OR = 2.95, 95% CI 1.47–5.91, P < 0.01), preoperative hemoglobin (OR = 1.97, 95% CI 1.28–3.03, P < 0.01), tumor site (OR = 0.28, 95% CI 0.22–0.36, P < 0.01), and treatment method (OR = 1.85, 95% CI 1.44–2.38, P < 0.01) were risk factors associated with PCF.

Conclusions

In our study, age, smoking, COPD, CAD, T-stage, previous radiotherapy, preoperative albumin, preoperative hemoglobin, tumor site, and treatment method were risk factors of PCF.
