目的　探讨急性左半结肠一期切除吻合术中肠减压方法 ,以便提高手术的安全性。方法　回顾性分析急性左半结肠梗阻一期吻合术中所用“手术台上灌洗法”16例和“经切除肠段减压法”9例两种肠减压术。结果2 5例均未发生吻合口漏 ,创口一期愈合。结论　对病程短 ,肠梗阻程度较轻者两种减压法均可使用 ,且以“经切除肠段减压法”为佳 ;反之 ,以“手术台上灌洗法”较为安全 Objective To investigate the method of mid-intestinal decompression for acute primary left colon resection and anastomosis in order to improve the safety of surgery. Methods A retrospective analysis of the first stage of anastomosis in patients with acute left colon obstruction “operation table lavage method” in 16 cases and “bowel decompression” 9 cases of two intestinal decompression. Results 25 cases had no anastomotic leakage, wound healing. Conclusion For short duration of disease, intestinal obstruction less severity of both decompression can be used, and to “cut the bowel decompression method is better; the other hand,” operating table lavage method "is more secure
