“…This study was implemented from July through December 2014 as part of a larger research project investigating the use of doppler-guided transanal hemorrhoidal dearterialization (THD) in treating patients with hemorrhoid disease grades III and IV. A previous study was conducted that reported on anorectal HRAM values among hemorrhoidal patients before and after THD [13]. In the current study, all participants were healthy volunteers recruited from the pool of medical students at Vietnam University of Traditional Medicine in Hanoi.…”

“…Previous studies from various countries have reported related values [8,[10][11][12]. In Vietnam, HRAM technique is relatively common, and a study comparing HRAM values in patients before and after doppler-guided transanal hemorrhoidal dearterialization has previously been published [13]. However, there are no known studies regarding HRAM values in healthy people.…”

Background 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. Methods 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. Results 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. Conclusions 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.

“…[8][9][10][11] In Vietnam, a single study using HRAM has been conducted, which reported values in patients with hemorrhoids before and after doppler-guided transanal hemorrhoidal dearterialization. 12 Although the HRAM technique has become commonly used in Vietnam, normal HRAM values have not been available until now. Therefore, the aim of the present study is to identify normal HRAM values and related factors in healthy Vietnamese adults.…”

Introduction The present study aims to identify normal high-resolution anorectal manometry (HRAM) values and related factors in healthy Vietnamese adults. Methods The present cross-sectional study was conducted at the Viet Duc hospital, Hanoi, Vietnam, during April and May 2019. Healthy volunteers were recruited to participate in the study. Anorectal measurement values from the digestive tract, including pressure, were recorded. Results A total of 76 healthy volunteers were recruited. The mean functional anal canal length was 4.2 ± 0.5 cm, while the mean anal high-pressure zone length was 3.4 ± 0.5 cm. The mean defecation index was 1.4 ± 0.8, with values ranging from 0.3 to 5.0. The mean threshold volume to elicit the rectoanal inhibitory reflex (RAIR) was 18.1 mL. The mean rectal sensation values were 32.4 mL, 81.6 mL, and 159 mL for first sensation, desire to defecate, and urge to defecate, respectively. Dyssynergic patterns occurred in ∼ 50% of the study participants and included mainly types I (27.6%) and III (14.6%). There were significant differences between male and female patients in terms of maximum anal squeeze pressure, maximum anal cough pressure, maximum anal strain pressure, maximum rectal cough pressure, and maximum rectal strain pressure (all p < 0.01). Conclusions The present study establishes normal HRAM values in healthy Vietnamese adults, particularly regarding normal values of anorectal pressure and rectal sensation. Further studies that include larger sample sizes should be conducted to further confirm the constants and their relationships.

Background This study aims to identify normal HRAM values and related factors in healthy Vietnamese adults. Methods This cross-sectional study was conducted at Viet Duc hospital, Hanoi, Vietnam, during April and May, 2019. Healthy volunteers were recruited to participate in the study. Anorectal measurement values including pressure and an electromyographical signal from the digestive tract were recorded. Differences between groups were analyzed using paired t-tests, and linear regression models was used to compare anorectal values between men and women. Results A total of the 76 healthy volunteers was recruited. The mean functional anal canal length was 4.2 ± 0.5 cm while the mean anal high-pressure zone (HPZ) length was 3.4 ± 0.5 cm. The mean defecation index was 1.4 ± 0.8, with values ranging from 0.3 to 5.0. The mean threshold volume to elicit RAIR was 18.1 mL. Mean rectal sensation values were 32.4 mL, 81.6 mL, and 159 mL at the first sensation, the desire to defecate, and the urge to defecate, respectively. Dyssynergic patterns occurred in approximately 50% of study participants and included mainly types I (27.6%) and III (14.6%). There were significant differences between males and females in maximum anal squeeze pressure, maximum anal cough pressure, maximum anal strain pressure, maximum rectal cough pressure, and maximum rectal strain pressure (all p < 0.01). Conclusions This study establishes normal HRAM values in healthy Vietnamese adults, particularly with regards to normal values of anorectal pressure and rectal sensation. Further studies that include larger sample sizes should be conducted in order to further confirm the constants and their relationships.
