정상 한국인에서 성별이 항문 직장 내압에 미치는 영향 = Effect of Sex on Anorectal Manometry in Healthy Korean

다국어 초록 (Multilingual Abstract)

In 30 healthy volunteers (15 women; mean age. 45.7:15 men; mean age, 33), anorectal manometry was done to determine whether rectal or anal function is affected by sex. The high fidelity infusion system was used and tracings were coded, read and interpreted by two blind observers. Sex did not affect anal basal pressure, maximal rectal squeeze pressure, threshold of rectosphincteric reflex (RSR), threshold of sense, critical volume, constant relaxation volume and amplitude of RSR with 60 ml rectal distention, But basal rectal pressure, maximal anal squeeze pressure and anal pullthrough pressure at rest were significantly higher; and anal length, longer, in males than in females. The threshold of sense is 33.6 (±11.6) ml in man, 38.5 (±11.0) ml in woman, the critical vloume 121.4 (±41.0) ml in man, 102 (±28.3) ml in woman. These results are different from those published in Western country. But estimation of threshold of sense and critical volume is based on subjective terms and has relatively reduced reproducibility. Therefore, in order to obtain constant and reliable results, threshold of RSR or constant relaxation volume can be used in routine anorectal manometry.
