结肠的血供与小肠相比较差,且肠内容物含大量细菌,所以结肠的手术尤其左半结肠肿瘤切除均提倡术前充分肠道准备.急诊手术因无法进行充分的肠道准备,以往多采用2期或分期手术方法,以策安全.但二期手术延长住院时间,给病人生活带来不便且可增加癌肿扩散机会.我院自1988年以来,对左半结肠肿瘤引起急性梗阻29例中的23例急诊行左半结肠肿瘤1期切除吻合.经观察随访无1例发生吻合口瘘或梗阻等并发症,疗效显著. The blood supply of the colon is poor compared with the small intestine, and the intestinal contents contain a large amount of bacteria. Therefore, the colon surgery, especially the resection of left colon tumors, advocates the full preparation of the bowel before surgery. The emergency surgery can not perform adequate bowel preparation. Two-stage or staging methods are recommended for safety. However, the second stage of surgery prolongs the hospitalization time, inconveniencing the patient’s life and increasing the chance of cancer spread. Our hospital has caused 29 cases of acute obstruction of left colon tumor since 1988. Among the 23 cases, emergency resection and anastomosis of left colon tumors were performed. There were no complications such as anastomotic leakage or obstruction during the follow-up observation. The curative effect was significant.
