贲门癌进胸切除术时因腹腔内暴露较差,淋巴清扫较为困难,仅能达 R_1或 R_1~+。这对中晚期贲门癌来说是不够的。本科自1988年9月以来对贲门癌行左后外切口,采用第八或第九肋床进胸,弧形广范切开膈肌,充分暴露上腹腔脏器,作近端胃大部切除,能达到 R_2以上的淋巴清扫,近期效果满意。 Because of poor intra-abdominal exposure during cardiac resection of cardiac cancer, lymphatic dissection is more difficult and can only reach R_1 or R_1~+. This is not enough for advanced cardia cancer. Undergraduate left and right external incisions for cardiac cancer since September 1988, using the eighth or ninth ribbed bed into the chest, wide arc-shaped incision of the diaphragm, fully exposed upper abdominal organs for proximal gastrectomy, Can achieve lymphatic dissection above R_2, the recent results are satisfactory.
