Objective: To understand the current practice of preoperative bowel preparation in elective colorectal surgery in China. Methods: A cross-sectional questionnaire survey was conducted through wechat. The content of the questionnaire survey included professional title of the participants, the hospital class, dietary preparation and protocol, oral laxatives and specific types, oral antibiotics, gastric intubation, and mechanical enema before elective colorectal surgery. A stratified analysis based on hospital class was conducted to understand their current practice of preoperative bowel preparation in elective colorectal surgery. Result: A total of 600 questionnaires were issued, and 516 (86.00%) questionnaires of participants from different hospitals, engaged in colorectal surgery or general surgeons were recovered, of which 366 were from tertiary hospitals (70.93%) and 150 from secondary hospitals (29.07%). For diet preparation, the proportions of right hemicolic, left hemicolic and rectal surgery were 81.59% (421/516), 84.88% (438/516) and 84.88% (438/516) respectively. The average time of preoperative dietary preparation was 2.03 days. The study showed that 85.85% (443/516) of surgeons chose oral laxatives for bowel preparation in all colorectal surgery, while only 4.26% (22/516) of surgeons did not choose oral laxatives. For mechanical enema, the proportions of right hemicolic, left hemicolic and rectal surgery were 19.19% (99/516), 30.04% (155/516) and 32.75% (169/516) respectively. Preoperative oral antibiotics was used by 34.69% (179/516) of the respondents. 94.38% (487/516) of participants were satisfied with bowel preparation, and 55.43% (286/516) of participants believed that preoperative bowel preparation was well tolerated. In terms of preoperative oral laxatives, there was no statistically significant difference between different levels of hospitals [secondary hospitals vs. tertiary hospitals: 90.00% (135/150) vs. 84.15% (308/366), χ(2)=2.995, P=0.084]. Compared with the tertiary hospitals, the surgeons in the secondary hospitals accounted for higher proportions in diet preparation [87.33% (131/150) vs. 76.78% (281/366), χ(2)=7.369, P=0.007], gastric intubation [54.00% (81/150) vs. 36.33% (133/366), χ(2)=13.672, P<0.001], preoperative oral antibiotics [58.67% (88/150) vs. 24.86% (91/366), χ(2)=12.259, P<0.001] and enema [28.67% (43/150) vs. 15.30% (56/366), χ(2)=53.661, P<0.001]. Conclusion: Although the preoperative bowel preparation practice in elective colorectal surgery for most of surgeons in China is basically the same as the current international protocol, the proportions of mechanical enema and gastric intubation before surgery are still relatively high.
目的： 了解中国择期结直肠手术术前肠道准备现状。 方法： 采用横断面调查方法进行问卷调查。以微信问卷星形式进行，问卷调查涉及的内容为参与调查者职称、所在单位级别，择期结直肠手术术前是否进行饮食准备及饮食准备方案、术前是否口服泻药及口服泻药种类、术前是否常规口服肠道制菌药物、术前是否留置胃管或进行机械性灌肠等。按参与调查医师所在医院等级不同做分层分析，了解不同层面医院的医师对择期结直肠手术患者的胃肠道准备情况。 结果： 共发出600份调查问卷，回收516份（86.00%）来自不同医院、从事结直肠外科或普通外科医生参与的调查问卷，其中三级医院366份（70.93%），二级医院150份（29.07%）。调查结果显示，右半结肠手术行饮食准备的比例为81.59%（421/516），左半结肠和直肠手术的比例均为84.88%（438/516），平均饮食准备时间为2.03 d。有85.85%（443/516）医生选择在所有结直肠手术前常规口服泻药进行肠道准备，仅有4.26%（22/516）的医生选择不口服泻药。对右半结肠、左半结肠及直肠手术采用机械性灌肠的医生比例分别为19.19%（99/516）、30.04%（155/516）和32.75%（169/516）。另有34.69%（179/516）的医生选择术前口服抗菌药物。94.38%（487/516）的医生对通过实施肠道准备后患者肠道清洁度表示满意，55.43%（286/516）的医生认为患者对实施的胃肠道准备方案耐受良好。在术前口服泻药方面，不同级别医院差异无统计学意义[二级医院比三级医院：90.00%（135/150）比84.15%（308/366），χ(2)=2.995，P=0.084]；与三级医院比较，二级医院的医师进行饮食准备[87.33%（131/150）比76.78%（281/366），χ(2)=7.369，P=0.007]、留置胃管[54.00%（81/150）比36.33%（133/366），χ(2)=13.672，P<0.001]、口服肠道抗菌药物[58.67%（88/150）比24.86%（91/366），χ(2)=12.259，P<0.001]及选择机械性灌肠的比例更高[28.67%（43/150）比15.30%（56/366），χ(2)=53.661，P<0.001]。 结论： 虽然国内大部分医生对择期结直肠手术术前肠道准备与国际上的主流方法基本一致，但在术前行机械性灌肠及留置胃管的比例仍较高。.
