目的探讨大肠癌术后便秘的发生率与手术部位及手术方式的关系。方法回顾性分析2004年6月～2005年7月行结肠镜检查的132例大肠癌术后患者,对随访结果进行分析和总结。结果右半结肠根治术、左半结肠根治术、乙状结肠癌根治术、直肠癌根治术患者术后便秘发生率分别为4.00%、6.25%、11.11%及32.88%;其中高位、低位、超低位直肠癌患者术后便秘发生率分别为20.00%、26.32%、41.03%(P<0.05);大内径吻合器与小口径吻合器吻合的患者术后便秘发生率分别为28.57%和35.56%(P<0.05)。结论大肠癌患者中术后发生便秘的主要为直肠癌患者,且原发肿瘤距离肛门越近便秘发生率越高;使用小内径吻合器的患者术后便秘发生率也较高。
Objective To investigate the relationship between the incidence of postoperative constipation and the surgical site and surgical approach in patients with colorectal cancer. Methods Retrospective analysis of 132 patients with colorectal cancer undergoing colonoscopy from June 2004 to July 2005 was performed. The follow-up results were analyzed and summarized. Results The incidences of postoperative constipation in patients with right colon resection, left radical colon surgery, radical resection of sigmoid colon cancer, and radical resection of rectal cancer were 4.00%, 6.25%, 11.11% and 32.88% respectively. The high, low, The incidences of postoperative constipation in patients with cancer were 20.00%, 26.32% and 41.03%, respectively (P <0.05). The incidences of postoperative constipation in patients with large diameter anastomosis and small caliber anastomosis were 28.57% and 35.56%, respectively (P < 0.05). Conclusions The main postoperative constipation in patients with colorectal cancer is rectal cancer patients, and the incidence of constipation in the primary tumor is higher from the anus. The incidence of postoperative constipation in patients with small diameter stapler is also higher.
