Abstract
This paper retrospectively compares post-operative complications, mortality and long-term survival of patients with esophageal carcinoma who were treated with standard esophagectomy or with extended two-field lymph node clearance. Fifty-seven patients with resectable esophageal carcinoma were included in the study. Twenty-eight patients were submitted to a radical two-field esophagectomy and lymphadenectomy, while the remaining 29 were submitted to a standard, more conservative, esophagectomy performed mostly through a transhiatal route. The two groups of patients were similar in all clinical, laboratory and pathologic features. There was a significant lower anastomotic leakage rate in the group of patients submitted to a radical lymph node resection; post-operative respiratory complication rate and mortality were similar in both groups. The overall 5-year survival was 20%. When lymph node resection was performed, the 5-year survival rate rose to 36%; it was 44% when nodal involvement was negative and 19% for N1 patients; when standard esophagectomy was the procedure, these figures were 9% (p < 0.05), and 6% respectively.
