Objective:
To compare outcomes of left and right thoracic incision for middle and lower thoracic esophageal squamous cancer, and to determine reasonable surgical approach for thoracic esophageal squamous carcinoma.
Methods:
One hundred and twenty patients with middle or lower thoracic esophageal squamous cancer who received esophagectomy plus lymphadenectomy between January 2004 and December 2007 were divided into two groups including left(n=60) and right thoracic(n=60) approach. Clinical data were analyzed including the results of surgical resection, lymphadenectomy, postoperative complication, recurrence, and survival.
Results:
The rate of surgical resection was 91.7%(55/60) in the left approach group and 95%(57/60) in the right approach group. There was no significant difference(P>0.05). But the average number of lymph nodes resected (4.60 vs. 8.32) and metastatic lymph nodes(0.57 vs. 1.33) were both significantly higher in the right approach group(P<0.01). There was no statistical difference in postoperative complications[26.7%(16/60) vs. 31.7%(19/60), P>0.05] between the two groups. However, the incidence of local recurrence was lower[43.3%(26/60) vs. 23.3%(14/60), P<0.05] in the right approach group than that in left-approach group. There was no significant difference in distant metastasis(P>0.05).
Conclusions:
The resection rate is comparable between left and right approach for thoracic esophageal cancer. However, it is easier to perform systemic lymphadenectomy via right thoracic approach and therefore the local recurrence is reduced and long-term survival improved.
