title: Barium swallow is a predictor of salivary fistula following laryngectomy.
abstract: Pharyngocutaneous salivary fistula after laryngectomy is a serious complication that can lead to prolonged hospitalization and increased patient morbidity. A postoperative barium swallow provides the surgeon with information regarding the integrity of the pharyngeal suture line. In an attempt to determine whether this information can be used to predict or prevent salivary fistula, we reviewed the records of 109 patients who underwent total laryngectomy, including 51 who had a barium swallow before they began oral intake. Ten patients (20%) demonstrated a sinus tract originating from the pharyngeal suture line. A clinical salivary fistula developed in all four patients with a sinus tract 2 cm or longer, but in only one of six patients with a tract shorter than 2 cm. Other factors predictive of salivary fistula included tumor stage, previous radiation therapy, and the presence of concurrent postoperative complications. A single fistula developed in the 58 patients not studied with barium. Information provided by postlaryngectomy barium swallow appeared to predict, but not prevent salivary fistula formation.
