Primary versus secondary tracheoesophageal puncture for voice rehabilitation in laryngectomy patients: A systematic review.

BACKGROUND

Among voice restoration options following laryngectomy, tracheoesophageal puncture (TEP) appears to be the most common. Currently, there is no consensus that exists with regard to the timing of performing TEP and the decision to perform a primary or secondary TEP has mostly been based on physician preference and expert opinion rather than data.

OBJECTIVE OF REVIEW

The objective of this study was to compare primary and secondary tracheoesophageal puncture (TEP) for voice rehabilitation in laryngectomy patients in terms of success and complication rates.

TYPE OF REVIEW

A systematic review of studies in the English literature was conducted for studies that directly compared primary and secondary TEP.

SEARCH STRATEGY

A comprehensive search of MEDLINE (January 1948-15 July 2016), EMBASE (January 1974-15 July 2016) and Web of Science (January 1970-15 July 2016) was performed.

EVALUATION METHOD

Two authors (KL/BAC) independently reviewed titles and abstracts, read full-text papers, extracted data and assessed quality. Disagreements were resolved via consensus. A third author (DV) resolved disagreements between reviewers when consensus was not possible.

RESULTS

Eleven retrospective clinical cohort studies were included. No randomised controlled trials were identified. Newcastle-Ottawa score for assessment of quality ranged from 5 to 7. Success rate was defined differently across most studies. Two studies found higher success with primary TEP compared to secondary TEP; nine studies found no difference. Voice outcomes were inconsistently measured; no difference between groups was found in 4 studies. Complication rates were divided into TEP site related, infectious and stenosis. No difference between primary and secondary TEP was found in all but one study which showed a higher rate of pharyngocutaneous fistula in the primary TEP group in salvage laryngectomy patients.

CONCLUSIONS

There is no robust evidence to suggest that primary TEP is associated with poorer outcomes compared to secondary TEP. A well-designed randomised controlled trial is required to appropriately answer this question.
