Abstract | BACKGROUND:
Chylothorax is an uncommon complication of esophagectomy. It carries significant morbidity and mortality. The predisposing factors are ill-defined. METHODS: RESULTS: Four patients (8.88 %) had chylothorax. On analysis of perioperative factors, it was found that patients with chylothorax had tumor in middle third of thoracic esophagus (100 %), shown partial response to neoadjuvant chemoradiation (NACRT) (100 %) and were associated with difficult mediastinal dissection (75 %) leading to higher blood loss requiring transfusion unlike those without chylothorax. There was no significant difference in the incidence of chylothorax following transhiatal, 3/35 = 8.57 % or transthoracic esophagectomy 1/10 = 10 % (p = 0.898). Three patients were managed by transabdominal en masse ligation of tissue between aorta and azygos vein while one patient was managed conservatively. Patients were discharged after a mean hospital stay of 15.5 days. The 30-day mortality rates in the two groups were similar (0 % vs. 4.8 %). CONCLUSION: Difficult mediastinal dissection during esophagectomy in middle esophageal cancer may lead to thoracic duct injury. Complete response to NACRT may reduce the risk of chylothorax. Early transabdominal en masse ligation carries excellent results. Low output fistula following thoracic duct injury can be managed conservatively.
