为了减少直肠癌手术后的感染,在直肠癌手术前除了需要一般的手术前准备,如纠正水电解质失衡和贫血等外,还必须进行结肠内良好的手术前准备。作者80年代初期在解放军301医院工作时已开始应用口服甘露醇和抗生素的肠道准备方法。1989年1月至1995年10月间作者在解放军307医院工作期间对94例直肠癌根治手术前肠道准备及抗生素的选择作了进一步研究。兹介绍给同道。本组直肠癌94例,男性46例,女性48例。年龄24～74岁,平均52.3岁。行经腹会阴直肠癌根治术(Miles手术)61例,其中会阴部切口感染4例(占4.3%),伤口经换药后愈合。经腹部直肠癌切除吻合手术(Dixon手术)33例,无吻合口瘘发生,也无切口感 In order to reduce the infection after rectal cancer surgery, in addition to the general preoperative preparation before surgery for rectal cancer, such as correcting the imbalance of water and electrolytes and anemia, it is also necessary to perform good preoperative preparation in the colon. In the early 1980s, when he began working at the People’s Liberation Army 301 Hospital, he had begun to use oral preparations for the oral administration of mannitol and antibiotics. From January 1989 to October 1995, the author further studied 94 cases of rectal cancer before bowel cancer surgery and antibiotic choice during the work of the People’s Liberation Army 307 Hospital. I will introduce it to colleagues. This group of 94 cases of rectal cancer, 46 males and 48 females. Age 24-74 years old, average 52.3 years old. Sixty-six patients underwent transperineal rectal cancer surgery (Miles operation), including 4 cases of perineal incision infection (4.3%). The wounds healed after dressing change. 33 cases of rectal cancer resection and anastomosis (Dixon surgery), no anastomotic leakage occurred, and no incision
