Introduction:
Amatsu's tracheoesophageal shunt can be indicated for vocal rehabilitation in candidates to total laryngectomy. It is performed in the period of the procedure of total laryngectomy and has been indicated due to its technical facility, exemption from the use of voice prosthesis, and lack of additional costs for its maintenance.
Objective:
To evaluate the results obtained with the Amatsu's tracheoesophageal shunt, along 14 years of experience, in two Brazilian hospitals.
Study Design:
Clinical retrospective.
Material And Method:
From 1991 to 2005, eighty-four patients were submitted to the Amatsu's tracheoesophageal shunt. Seventy-seven (91.7%) were male and seven (8.3%) female, aged between 30 and 82 years, mean age of 57.5 years, and an average age of 52 years. All patients had squamous cell carcinoma of larynx and/or hypopharynx. Sixty-eight (81.0%) were stage III or IV. They were submitted to total laryngectomy and the Amatsu's tracheoesophageal shunt was performed during the tumor removal surgery. The following variables were analyzed: acquisition of intelligible speech, vocal recovery time after surgery, and the occurrence of specific surgical complications of the shunt (pulmonary aspiration).
Results:
Seventy-six patients were evaluated with respect to the effectiveness of the technique. Fifty-three patients (70.0%) presented vocalization by the shunt; in 46 patients (60.5%), the speech was fully intelligible. The time required for restoration of speech was 12-87 postoperative days. Of the 83 patients evaluated in relation to the development of complications, 25 (30.1%) presented aspiration by the shunt during oral ingestion. In 23 patients (27.7%), the aspiration was managed conservatively without complications. Two patients (2.4%) required surgical closure of the shunt due to intractable aspiration.
Conclusion:
Vocal rehabilitation with the Amatsu's tracheoesophageal shunt is effective in most patients who underwent total laryngectomy. It can be evidenced by the acquisition of intelligible speech in most patients. The aspiration, although often, is not shown to be a limiting complication.
