High-resolution anorectal manometry (HRAM) has been developed to improve measurement of anorectal functions. This study aims to identify normal HRAM values in healthy young Vietnamese adults. We conducted a cross-sectional study at the National Hospital of Traditional Medicine (Hanoi, Vietnam) from July through December 2014. Healthy young adults were invited to participate in the study. All anorectal measurement values were performed using the ISOLAB high-resolution manometry system. Differences between groups were analyzed using Student’s t-tests. Thirty healthy young adults, including 15 males and 15 females aged 19–26 years, were recruited. Mean functional anal canal length was 3.4 ± 0.5 cm (range: 2.4–4.8 mm). Mean maximum resting pressure, mean maximum squeezing pressure, mean maximum coughing pressure, and mean maximum strain pressure were 65.5, 168.0, 125.9, and 84.2 mm Hg, respectively. All anal pressure values were significantly different between males and females. For rectal sensation measurements, only the volume at first sensation was significantly higher in males than in females. This study provides normal HRAM value for healthy young adults in Vietnam. Sex may influence anal pressure and first rectal sensation values in this cohort. Further studies should be conducted in order to improve the quality of HRAM normal values and to confirm the effects of sex.

健康年轻人高分辨率肛门直肠测压的正常值：来自越南的证据

高分辨率肛门直肠测压 (HRAM) 已被开发用于改善肛门直肠功能的测量。本研究旨在确定健康的越南年轻人的正常 HRAM 值。我们于 2014 年 7 月至 12 月在国立传统医学医院（越南河内）进行了一项横断面研究。健康的年轻人被邀请参加这项研究。所有肛门直肠测量值均使用 ISOLAB 高分辨率测压系统进行。使用Student's t-检验分析组间差异。招募了 30 名健康的年轻人，包括 15 名男性和 15 名 19-26 岁的女性。平均功能性肛管长度为 3.4 ± 0.5 厘米（范围：2.4-4.8 毫米）。平均最大静息压力，平均最大挤压压力，平均最大咳嗽压力，和平均最大应变压力分别为 65.5、168.0、125.9 和 84.2 毫米汞柱。男性和女性的所有肛门压力值都有显着差异。对于直肠感觉测量，只有男性的第一感觉体积明显高于女性。这项研究为越南健康的年轻人提供了正常的 HRAM 值。性别可能会影响该队列中的肛门压力和直肠第一感觉值。应进行进一步研究以提高 HRAM 正常值的质量并确认性别的影响。这项研究为越南健康的年轻人提供了正常的 HRAM 值。性别可能会影响该队列中的肛门压力和直肠第一感觉值。应进行进一步研究以提高 HRAM 正常值的质量并确认性别的影响。这项研究为越南健康的年轻人提供了正常的 HRAM 值。性别可能会影响该队列中的肛门压力和直肠第一感觉值。应进行进一步研究以提高 HRAM 正常值的质量并确认性别的影响。
