[Comparison of thoraco-laparoscopic and open three-field subtotal esophagectomy for esophageal cancer].

Objective: To evaluate the safety and efficacy of thoraco-laparoscopic subtotal esophagectomy in the treatment of esophageal cancer.

Methods: Clinical data of 98 patients with esophageal cancer who underwent thoraco-laparoscopic subtotal esophagectomy from March 2009 to October 2011 were retrospectively analyzed. One hundred and five patients were served as controls who underwent open three-field subtotal esophagectomy in the same period.

Results: There were significant differences between thoraco-laparoscopic and open three-field subtotal esophagectomy in blood loss [(85.1±32.8) ml vs. (215.5±60.6) ml], length of stay [(12.7±3.5) d vs. (16.9±4.5) d]), pneumonia (4.1% vs. 12.4%, P<0.05), atelectasis (3.1% vs. 10.5%, P<0.05), pleural effusion (3.1% vs. 10.5%, P<0.05), acute respiratory distress (1.0% vs. 7.6%, P<0.05) and arrhythmia (4.1% vs. 12.4%, P<0.05). No significant differences were observed in the number of lymph node harvested, operative time, anastomotic leak, thoracic abscess, chyle chest, re-laparotomy, re-thoracotomy, vocal cord paralysis, renal failure, gastric emptying, and mortality (all P>0.05).

Conclusion: Thoraco-laparoscopic subtotal esophagectomy is technically feasible and safe and is associated with less blood loss, less cardiopulmonary complication, and shorter hospital stay.
