肛管直肠压力测定的临床观察

Clinical Observation on Anorectal Manometry

为了探讨肛管直肠测压技术的临床应用和意义，应用美国Medtronic公司生产的polygram 98多道胃肠压力测定系统对200例肛肠科术前患者进行肛肠压力测定。结果肛裂组肛管缩榨压比正常组明显降低（P〈0．01），排便困难组直肠肛管静息压比正常组明显降低（P〈0．05）。其余痔、肛裂、肛瘘、排便困难组的各项检测指标与正常组无统计学差异，其各组间相比也无统计学差异。结果表明，直肠肛管测压检查，直肠静息压、肛管静息压、缩榨压、压榨压这4种指标对痔、瘘、裂的诊断不敏感。直肠肛管测压结果受多方面因素的影响。

The objective of the study was to investigate the clinical significance of anorectal manometry. Two hundreds patients with anorectal diseases underwent preoperative anorectal manometry with multichannel gastrointestinal manometric system（polygram 98, made in Medtronic Company, USA）. As results, the anal squeeze pressure（i, e Max. auto-constriction pressure） in the anal fissure group was markedly reduced against that in the normal group（ P 〈0.01）,and the rectoanal rest pressure in the defecation disorder group was notably lowered compared with the normal group （ P 〈0. 05）. There was no statistical difference in the detected indexes in hemorrhoid group ,anal fissure group, anal fistula group and defecation disorder group,compared with the normal group,as well as compared between all the groups. It is revealed that the indexes such as rectal rest pressure,anal rest pressure,squeeze pressure and pressing ＆ squeezing pressure are not sensitive to the diagnosis of hemorrhoids, fistula and fissure; and that the results of anorectal manometry are influenced by multiple factors.
