对于左半结肠癌伴梗阻的外科治疗 ,长期以来遵循传统的分期多次手术方式 ,即一期结肠造瘘减压 ,二期结肠切除吻合及闭瘘或采用三期闭瘘[1] 。分期切除虽比较安全 ,但增加了患者的痛苦 ,加重了患者的经济负担 ,并增加了癌肿转移的机会 ,而可能导致延误根治性切除的时机。本治疗 Surgical treatment of left-sided colon cancer with obstruction has long followed the traditional staging of multiple surgeries, ie, stage I colonic fistula decompression, secondary resection and anastomosis and closed fistula or stage III fistula [1].
