ObjectiveOrocutaneous and pharyngocutaneous fistula (OPCF) is a debilitating complication of head and neck surgery for squamous cell carcinoma (SCC), resulting in delayed adjuvant treatment and prolonged hospitalization. As yet, there is no established test that can help in prompt and accurate diagnosis of OPCF. This study aims to determine the accuracy of bedside blue dye testing and its role as part of an algorithm for early diagnosis. We also analyze the risk factors predisposing to OPCF.Study DesignRetrospective cohort study from 2012 to 2014.MethodsPatients with head and neck SCC who underwent major resection and reconstruction, at risk of OPCF, were included. Results of blue‐dye and video‐fluoroscopic swallow‐studies (VFSS) testing for OPCF were recorded. For the patients that were noted to develop OPCF, the length of time to diagnosis of fistula and subsequent mode of management were examined.ResultsOf the 93 patients in this study, 25 (26.9%) developed OPCF. Advanced T‐classification (T3/T4) was the only significant predisposing risk factor (p = 0.013). The sensitivity and specificity of the bedside blue dye testing was found to be 36.4% and 100%, respectively. The test positive patients were diagnosed with OPCF at a median of postoperative day (POD) 9.5 as compared to POD 13 for the test negative patients (p = 0.001). Early diagnosis was associated with faster fistula resolution with treatment.ConclusionBlue dye testing is a simple bedside test that can assist in the early diagnosis of OPCF in patients, allowing treatment to be instituted earlier with improved outcomes.Level of Evidence3

HighlightsTORS for oropharyngeal tumour may predispose susceptible patients to invasive fungal infection and osteomyelitis.Susceptible patients included those with prior history of radiation at surgical site.Fungal infection can present as an exophytic mass at the surgical site.

Aims: Patient-reported outcome measures are important in assessing the impact of dysphagia on quality of life. Our aim was to adapt and examine the cultural validity and reliability of a swallowing-related quality of life measure, the MD Anderson Dysphagia Inventory (MDADI), in English and Chinese, with head and neck cancer patients. Methods: We adapted the MDADI to Chinese through formal forward-backward translation. Sixty-six head and neck cancer survivors completed the MDADI, Swallowing Quality of Life (SWAL-QOL) questionnaire and Hospital Anxiety and Depression Scale (HADS) in English or Chinese. Swallowing status was scored on the Functional Oral Intake Scale (FOIS). Seventy-four percent (n = 49) of participants completed a repeat administration of the MDADI for test-retest reliability analysis. Results: The MDADI showed high internal consistency reliability (Cronbach's α , 0.82 ≤ α ≤ 0.94), and test-retest reliability in both English (intraclass correlation coefficient, ICC = 0.81) and Chinese (ICC = 0.72). Criterion validity was established through moderate to strong correlations with relevant SWAL-QOL domains. Convergent validity was determined by significant correlations to the HADS and FOIS. Divergent validity was determined by nonsignificant association to the SWAL-QOL Sleep domain. The MDADI also presented as hypothesised to most known-group theoretical constructs. Conclusions: The MDADI showed good psychometric properties in English and Chinese. This avails a reliable and psychometrically valid MDADI for Chinese speakers.
