目的:探讨大肠癌根治术后肠梗阻的致病因素及治疗特点。方法:总结分析我院手术治疗的36例大肠癌根治术后肠梗阻患者的临床资料。结果:大肠癌术后腹腔炎症、粘连、腹内疝、吻合口瘘、狭窄及放射性损伤等因素引起的非肿瘤性肠梗阻较为多见(肿瘤性肠梗阻多为肿瘤复发、转移所致)。结论:引起非肿瘤性肠梗阻的病因较多,发病早,症状重,应及时手术探查,根据术中情况选择术式;肿瘤性肠梗阻发病较晚,进展缓慢,主要选择姑息手术缓解症状。 Objective: To explore the pathogenic factors and treatment characteristics of intestinal obstruction after radical operation of colorectal cancer. Methods: The clinical data of 36 patients with intestinal obstruction after radical operation of colorectal cancer underwent surgical treatment in our hospital were summarized and analyzed. Results: Non-tumor intestinal obstruction caused by peritoneal inflammation, adhesions, intra-abdominal hernia, anastomotic fistula, stenosis and radioactive injury after colorectal cancer were more common (tumor ileus mostly caused by tumor recurrence and metastasis). Conclusion: The cause of non-tumor intestinal obstruction more, the incidence of early, severe symptoms, surgical exploration should be promptly, according to intraoperative choice of surgical; tumor intestinal obstruction onset late, slow progress, the main choice of palliative surgery to relieve symptoms.
