OBJECTIVE: To investigate the incidence of @entity1600 ( @entity1600 ) in the right para-tracheal triangle (RPT) of @entity418 @entity1 and the technique of dissection. METHODS: On the top of double mediastinal and abdominal lymphadenectomy, 333 @entity418 @entity1 received RPT lymphadenectomy through the right pleural apical approach from 1990 to 2001. RESULTS: In these 333 @entity1 , the @entity1600 ( @entity1600 ) rate in the RPT was 36.40%. A total of 457 nodes among 2 159 nodes removed gave a @entity3 degree of 24.96%. The @entity1600 rates in RPT for cervical, upper third, middle third, and lower third segments of esophagus were 66.67%, 45.45%, 34.19% and 15.79% (P < 0.05), while their respective @entity3 degrees were 44.44%, 27.04%, 24.32% and 18.92% (P > 0.05). The frequency of positive nodes in the RPT for PTI, @entity2558 , PT2, @entity1803 and PT4 was 0, 17.24%, 28.7%, 45.16% and 53.57%, while those of @entity3 degree were 0, 8.77%, 17.62%, 33% and 41.17% (P < 0.01). The frequency of @entity1600 in the RPT in papillary, erosive, patch-like and covert type of early @entity5 was 40%, 3.85%, 0 and 0 (P < 0.05), while those of the @entity3 degree were 29.41%, 1.82%, 0 and 0 (P < 0.01). Higher rate of @entity1600 in progressive @entity418 was observed compared with those of the other gross types (56.52%, P < 0.05), so was the degree (P < 0.01). The frequency of @entity1600 in the RPT for mono-focal and multi-focal @entity5 was 34.98% and 70% without significant difference (P > 0.05), while the degree was 24.29% and 53.33% (P < 0.05). @entity260 were: leak (0.6%), and recurrent @entity13587 (1.2%). No @entity1317 , tracheal damage or mortality occurred. CONCLUSION: 1. The @entity1600 from @entity418 has a tendency of wide spread and right para-tracheal triangle is an important region to be doomed. 2. With location, depth of @entity5 invasion and differentiation of @entity5 as major factors affecting @entity1600 of @entity418 , dissection of this region should be paid more emphasis. 3. In early lesions, higher frequency of @entity1600 in the RPT is found in @entity5720 than in the other macroscopic types. 4. Exposing the RPT, lymph node by dissection through a right pleural apical approach is very important and significant.
