Abstract:
Objective To explore the normal values for two-dimension solid state high resolution anorectal manometry (HRAM) in healthy adult volunteers.Methods The healthy adult volunteers were recruited by advertisement and underwent solid state HRAM in the left lateral position.Anorectal pressures and rectal sensation were recorded and analyzed.Results (1) A total of 126 Chinese healthy adult volunteers (male:50 cases (39.7%);age:(37.5 ± 14.2) years old) were recruited in this study.(2)Mean anal resting pressure (MERP) was (71.8 ± 17.3) mmHg (1 mmHg =0.133 kPa).Maximum anal resting pressure (MARP) was (79.3 ± 17.8) mmHg,Maximum anal squeeze pressure (MSP) was (178.7 ± 52.8) mmHg.Anal high pressure zone (HPZ) length was (3.4 ± 0.6) cm.During simulated evacuation,residual anal pressure (RAP) was (63.8 ±20.5) mmHg,and anal relaxation rate (ARR) was (37.0 ± 11.5) %.Rectal threshold volume for first sensation (FST),desire to defecate (DDT),urgency to defecate (UDT) and maximum discomfort (MDT) was (47.4 ±10.0) ml,(84.5 ±18.2) ml,(125.8 ± 28.5) ml,and (175.5 ±36.1) ml,respectively.(3) Compared with female subjects,male subjects had higher MSP [(211.0 ± 50.7) mmHg vs (157.5 ± 42.5) mmHg],RAP [(71.6 ± 18.1) mmHg vs (58.8 ± 20.5) mmHg]and rectal MDT[(187.0 ±36.4) mmHg vs (168.0 ±34.1)mmHg],but lower ARR [(32.1 ±8.0)% vs (40.2 ±12.3)%],all P<0.01.(4) MERP,MARP,MSP and rectal MDT were higher in young group (≤ 40 years old),all P < 0.05.Conclusions These observations provide normal values for two-dimension solid state HRAM,which have significant difference between genders and different age groups.
