分析左半结肠癌伴梗阻１２８例，其中部分梗阻７１例，完全梗阻５７例。两种梗阻从病理类型上差别不大，但完全梗阻病例Ｄｕｋｅｓ分期较晚，肿瘤切除机会少，死亡率高。对左半结肠癌疑有部分性梗阻者，应禁用泻剂，并注意灌肠方法；入院后应禁止粗纤维食物，而进食流质或禁食，以防止部分梗阻转变为完全性梗阻。为防止急性梗阻的闭襻性结肠发生穿孔，对完全性梗阻者应积极纠正水电解质紊乱和休克，一旦全身情况稳定即应手术。同时讨论了处理部分性和完全性左半结肠癌伴梗阻的几种术式，认为术中结肠灌洗是对左半结肠癌伴梗阻进行急诊处理的一个好方法
Analysis of 128 cases of obstruction of the left colon cancer, including 71 cases of partial obstruction, complete obstruction in 57 cases. There was no significant difference in pathological type between the two types of obstruction, but the complete obstruction was later in Dukes stage, with less chance of tumor resection and high mortality. For those with suspected partial obstruction of left colon cancer, laxatives should be banned and enema therapy should be used. Crude fiber foods should be banned after admission and fluid or fasting should be taken to prevent partial obstruction from becoming complete obstruction. In order to prevent perforation of closed obstructive colon in acute obstruction, patients with complete obstruction should actively correct water-electrolyte disorder and shock, and should be operated once the general condition is stable. At the same time, we discussed several surgical methods for treating partial and complete left colon cancer with obstruction, and believe that intraoperative colonic lavage is a good method for emergency treatment of left colon cancer with obstruction.
