Factors that affect caecal intubation during colonoscopy include age and sex of the patient, quality of bowel preparation, prior abdominal or pelvic surgery and pelvic inflammatory disease, among others. The aim of this prospective study was to evaluate the effects of patients' demography such as age and sex, as well as anthropometry (height, weight and body mass index (BMI)) on caecal intubation time (CIT).
All consecutive patients referred for colonoscopy over a period of 6 months were recruited into the study. Prior to the procedure, patients' demographic data as well as history of prior abdominal or pelvic surgery were recorded. The height and weight of each patient were taken, and the BMI calculated. CIT was measured from the time of insertion of the colonoscope into the anal canal to the time when the base of the caecum was intubated.
A total of 167 patients comprising 99 (59.3%) males and 68 (40.7%) females were studied. The mean CIT of the procedures was 912.5±477.1 s with a range of 180-3180 s. It was more prolonged in patients older than 65 years of age, in males and in those with prior abdominal/pelvic surgery, although no significant difference was observed among the groups. Multivariate logistic regression analysis showed that increased BMI and non-usage of additional manoeuvres independently reduced CIT.
Older age, male gender, prior abdominal/pelvic surgery, use of additional manoeuvres and lower BMI were found to prolong CIT.
结肠镜检查时影响盲肠插管的因素包括患者的年龄、性别、肠道准备质量、既往腹部或盆腔手术史以及盆腔炎等。这项前瞻性研究的目的是评估患者的人口统计学特征（如年龄和性别）以及人体测量学指标（身高、体重和体重指数（BMI））对盲肠插管时间（CIT）的影响。
连续6个月内所有转诊来接受结肠镜检查的患者均纳入本研究。在检查前，记录患者的人口统计学数据以及既往腹部或盆腔手术史。测量每位患者的身高和体重，并计算BMI。CIT从结肠镜插入肛管开始至盲肠底部插管时止进行测量。
共研究了167例患者，其中男性99例（59.3%），女性68例（40.7%）。检查的平均CIT为912.5±477.1秒，范围为180 - 3180秒。65岁以上患者、男性以及有既往腹部/盆腔手术史的患者CIT更长，尽管各组之间未观察到显著差异。多因素逻辑回归分析显示，BMI增加和未使用额外操作可独立缩短CIT。
发现年龄较大、男性、既往腹部/盆腔手术史、使用额外操作以及BMI较低会延长CIT。
