BACKGROUND/AIMS: The length of colon is known to be longer in females than in males. In addition, the morphology of colon cancer is different between males and females. The aim of this study was to investigate sex differences in Boston bowel preparation score (BBPS) and colonoscopy insertion time.
This study retrospectively analyzed medical records and colonoscopy readings of subjects who underwent colonoscopy at Seoul National University Bundang Hospital from March 2015 to April 2018. BPPS was used to evaluate the degree of colon cleanness before colonoscopy. Statistical analysis was performed to compare demographic, clinical, and outcome variables between two groups.
The study group consisted of a total of 12,561 patients (6,148 females and 6,413 males). Mean age was 57.8 ± 13.5 years for females and 57.5 ± 13.8 years for males (p = 0.695). Females showed better bowel preparation than males (mean total score: 7.4 ± 1.8 vs. 7.2 ± 1.9, p = 0.001; total score ≥ 6: 5,340 [86.9%] vs. 5,437 [84.8%], p = 0.001; BBPS ≥ 2 for all segments: 5,048 [82.1%] vs. 5,097 [79.5%], p < 0.001). However, cecal intubation time (8.3 ± 6.2 minutes vs. 6.2 ± 6.1 minutes, p < 0.001) and withdrawal time (7.9 ± 3.5 minutes vs. 7.4 ± 3.1 minutes, p < 0.001) were longer in males.
There were sex differences in BBPS, cecal intubation time, and withdrawal time for subjects undergoing colonoscopy.
背景/目的：已知女性的结肠长度长于男性。此外，男性和女性的结肠癌形态也不同。本研究旨在探讨波士顿肠道准备评分（BBPS）和结肠镜插入时间的性别差异。
本研究回顾性分析了 2015 年 3 月至 2018 年 4 月在首尔国立大学盆唐医院接受结肠镜检查的患者的病历和结肠镜检查结果。BBPS 用于评估结肠镜检查前结肠的清洁程度。对两组的人口统计学、临床和结果变量进行了统计学分析。
研究组共纳入 12561 例患者（女性 6148 例，男性 6413 例）。女性的平均年龄为 57.8 ± 13.5 岁，男性为 57.5 ± 13.8 岁（p = 0.695）。女性的肠道准备情况优于男性（总评分均值：7.4 ± 1.8 比 7.2 ± 1.9，p = 0.001；总评分≥6 分：5340[86.9%]比 5437[84.8%]，p = 0.001；所有节段的 BBPS≥2 分：5048[82.1%]比 5097[79.5%]，p<0.001）。然而，男性的盲肠插管时间（8.3 ± 6.2 分钟比 6.2 ± 6.1 分钟，p<0.001）和退镜时间（7.9 ± 3.5 分钟比 7.4 ± 3.1 分钟，p<0.001）较长。
接受结肠镜检查的患者在 BBPS、盲肠插管时间和退镜时间方面存在性别差异。
