目的 探讨近十年来老年结肠癌致肠梗阻有关临床特点的变化和外科治疗的有关问题。方法 对 1988年～ 1998年手术治疗 65岁以上老年结肠癌梗阻 5 6例进行回顾性分析和总结。结果 结肠癌梗阻占老年急性肠梗阻的5 0 .91% ,居首位 ;梗阻发生部位以右半结肠区最多 ,占 5 5 .3 6% ,左半结肠区仅占 14 .2 9% ;有非恶性肿瘤手术史的老年肠梗阻中 5 0 %是结肠癌所致 ,有恶性肿瘤手术史中 9.1%是原发结肠癌所致。结论 1.提高对老年结肠癌梗阻临床特点的认识 ,正确地选择手术时机和合理的手术方式能获良好预后 ;2 .加强围手术期各器官功能支持和营养代谢支持是减少死亡率的重要环节 ;3 .重视老年生理变化特点 ,警惕肿瘤所致的消化道症状 ,早期诊治结肠癌以减少肠梗阻发病率
Objective To investigate the changes of clinical features of intestinal obstruction caused by colon cancer in the past decade and the related problems of surgical treatment. Methods A retrospective analysis and summary of 56 cases of elderly colon cancer older than 65 years old from 1988 to 1998 were performed. Results Colorectal cancer obstruction accounted for 50.91% of elderly patients with acute intestinal obstruction, with the highest incidence of right colon half, accounting for 55.36% and left half colon area accounting for 14.29%. Fifty percent of elderly intestinal obstruction with a history of non-malignant tumor surgery is caused by colon cancer, and 9.1% of the history of malignant tumor surgery is caused by primary colon cancer. 1. To improve the clinical features of elderly patients with colorectal obstruction awareness, the correct choice of timing and reasonable surgical operation can get a good prognosis; 2. To enhance perioperative organ function support and nutritional metabolism support is an important part of reducing mortality ; 3. Pay attention to the characteristics of physiological changes in the elderly, to guard against gastrointestinal symptoms caused by cancer, early diagnosis and treatment of colon cancer to reduce the incidence of intestinal obstruction
