[Incidence of salivary fistulas in relation to timing of oral nutrition after laryngectomy].
OBJECTIVE
A pharyngocutaneous fistula is the most common complication after total laryngectomy. In Germany, a traditional recommendation is to use a nasogastric tube for feeding for 10-14 days postoperatively because many surgeons believe that oral feeding after surgery contributes to fistula development. However, there is no international agreement about when to begin oral feeding after total laryngectomy. Some authors begin oral feeding between the 1st and 4th postoperative day without any nasogastric tube, while others using a nasogastric tube delay oral feedings until 7-14 days after surgery. The aim of the present study was to investigate the relationship between the timing of oral feeding and the development of fistulas after total laryngectomy.


METHODS
In a prospective trial with 42 consecutive patients who underwent laryngectomy, oral feeding was started on different postoperative days between the 1st and the 10th. Most patients were selected randomly for the different postoperative days. Furthermore, other potential risk factors predisposing to fistula formation were analyzed retrospectively.


RESULTS
Five fistulas occurred in the total group (12%). Early postoperative oral feeding does not increase the incidence of fistulas. The fistula rate was only 9% in patients fed orally in the 1st postoperative week. The analysis of further risk factors for fistula formation showed only a significant correlation between type of resection and fistula occurrence (extended laryngectomy with partial pharyngectomy vs standard laryngectomy; p = 0.018).


CONCLUSIONS
Our results indicate that early oral feeding in the 1st postoperative week does not influence fistula formation after laryngectomy.
