Retrosternal bypass operation for unresectable squamous cell cancer of the esophagus

Background. A palliative bypass operation may be beneficial when severe dysphagia or tracheoesophageal fistula occurs after radiochemotherapy for unresectable tumor of the esophagus. Methods. Thirty-two patients with an unresectable tumor of the esophagus underwent a palliative retrosternal gastric (29) or colonic (3) bypass operation with ligature of the lower esophagus (3) or drainage (27). Tracheoesophageal fistula was present at operation in 20 (62.5%), including 8 after radiochemotherapy. results. The overall operative mortality rate was 34.4%: 45% with tracheoesophageal fistula and 16.6% without (p < 0.01). Median intensive care and hospitalization times were 5 and 19 days, respectively. Median postoperative survival was 6 months (range, 53 to 492 days). Complications in 21 survivors were lung infections (seven), cervical fistulas (eight), and failure of the esophageal suture (two); 19 patients resumed oral nutrition, and quality of life was excellent in 6. All eight cervical fistulas regressed favorably. Postoperative radiotherapy or chemotherapy did not improve survival. conclusions. Despite the high operative mortality rate, bypass operation can provide good palliation and allow subsequent radiochemotherapy in selected patients with an unresectable tumor of the esophagus.
