Study of approaches in surgery of esophageal cancer / 中国癌症杂志

ABSTRACT

Purpose:To improve the methads of approach in s urgery of esophageal cancer ,increase resection rate of esophagectomy, decrease the remnant cancer in margin and mortality after operation, enhance the postoper ative effect. Methods:From Jan.1999 to Dec. 2002,we adopted different surgica l approach as in esophagectomy in 297cases with esophageal cancer, such as left posterior thoracotomy(group I), left posterior thoracotomy with cervical incisi on (group Ⅱ),right anterior thoracotomy (group Ⅲ), right posterior thoracotomy (group Ⅳ). Results:The rate of operative resection was 98.7%(293/297)an d for groups Ⅰ, Ⅱ, Ⅲ, Ⅳ they were 98.2%(86/87)、98.1%(52/53)、98.5%(133/135) 、100%(22/22) respectively;operation-related mortality was 1.7%(5/297) and fo r groups Ⅰ, Ⅱ, Ⅲ, Ⅳ it was 2.3%(2/87)、1.9%(1/53)、0.75%(1/135)、4.5%(1/22) respectively;the occurrence of remnant cancer was 3.8%(11/293) and for groups Ⅰ, Ⅱ, Ⅲ, Ⅳ it was 4.7%(4/86)、3.8%(2/52)、2.6%(3/133)、9.1%(2/22) respective ly;the rate of postoperative complication was 12.8%(38/297) and for groups Ⅰ, Ⅱ, Ⅲ, Ⅳ it was 17.2%(15/87)、9.4%(5/53)、11.1%(15/135)、13.6%(3/22) respectiv ely. In the number of lymph node resected , there was statistical difference bet ween groups Ⅲ, Ⅳ and Ⅰ, Ⅱ(P0.05).Conclusions:Right anterior thoracotomy, right posterior thoraco tomy were more satisfactory operative approaches in radical total thoracic esop hagectomy of esophageal carcinoma. Through these two approaches,we not only can resect mediastinal and abdominal lymph nodes radically, but can also decrease t he cancer of at the margin and mortality after operation.
