Cervical anastomotic fistula in surgery of the esophagus

: Cervical anastomotic fistula are reported in the surgical literature in 10-30% of the patients, providing a much longer hospitalisation, a higher morbidity and in some cases even mortality. Between 1997-2003, 91 patients underwent surgical treatment for esophageal cancers and 14 patients for chemical burns. In the cancer group the rate of resection was 67,03% (61 patients). In 8 patients with non-resection tumours a retrosternal esophageal by-pass with stomach was carried out. Cervical anastomosis were performed in 68 patients, by hand sutures. Anastomotic fistula were noted in 9 patients (13,24%). In 6 cases temporarily fistula occurred, with spontaneous healing by local treatment, in 8-28 days. 2 patients required reoperation and one patient a definitive feeding jejunostomy. Most common causes of fistula are technical problems, ischemic gastric or colonic tube, postoperative respiratory failure, with prolonged hypoxia. An anastomosis in the neck results in less postoperative complications than one of the lower level.
