Pharyngo-cutaneous fistula: an old problem revisited.

CONCLUSION

Pharyngo-cutaneous fistula is the most common complication after total laryngectomy (TL), with many factors linked to its emergence. However, it has rarely been associated with the type of pharyngeal suture. We conclude that the technique of surgical closure of the pharynx and care in the tightness of the suture seem to be fundamental factors for pharyngo-cutaneous fistula development.

OBJECTIVE

The aim of present work was to determine whether the type of pharyngeal suture can be considered as a major risk factor for developing a pharyngo-cutaneous fistula following TL.

METHODS

We carried out a series of 157 consecutive TLs. In the first 90 procedures, we performed a pharyngeal closure technique with T-shaped interrupted stitches reinforced with constrictors. In the other 67 cases, a doubled continuous suture technique with reinforcement with the cutaneous flap was developed.

RESULTS

In all, 25.5% of the cases sutured with the interrupted stitches developed a fistula while only 2.9% of the patients that underwent continuous suture developed a fistula.
