AJG: 使用阿片类药物患者的排便障碍是慢性便秘原因吗?

2019-11-30 不详 MedSci原创

目前我们对阿片类药物对肛门直肠功能的影响了解甚少,阿片类药物可能与引起便秘(OIC)的发病机制有关。本项研究旨在评估与未服用阿片类药物(NOIC)的便秘患者相比,长期服用阿片类药物(OIC)的便秘患者的肛门直肠功能测试(AFT)的特征,症状负担和生活质量。

目的:
目前我们对阿片类药物对肛门直肠功能的影响了解甚少,阿片类药物可能与引起便秘(OIC)的发病机制有关。本项研究旨在评估与未服用阿片类药物(NOIC)的便秘患者相比,长期服用阿片类药物(OIC)的便秘患者的肛门直肠功能测试(AFT)的特征,症状负担和生活质量。

方法:
研究人员回顾性分析了完成AFT的3452名(OIC = 588和NOIC = 2,864)慢性便秘患者的临床数据。AFT变量包括肛门括约肌压力和模拟排便时的反应,球囊排泄试验(BET)和直肠感觉。排尿障碍性排便(DD)被定义为在模拟排便和异常BET期间无法放松肛门括约肌。所有患者均完成了便秘症状的患者评估(PAC-SYM)和便秘生活质量的患者评估(PAC-QOL)问卷。

结果:
该研究队列的平均年龄为49岁。大多数患者是女性(82%)和白人(83%)。OIC患者比NOIC患者年龄更大(50.7 vs 48.3,P = 0.001)。OIC患者更可能患有DD(28.6%vs 21.4%,P <0.001),肛门直肠测压时模拟排便异常(59%vs 43.8%,P <0.001)和BET异常(48%vs 42.5%,P = 0.02)。OIC患者的便秘症状较NOIC患者更为严重(P <0.02),生活质量较差(P <0.05)。

讨论:
使用阿片类药物的慢性便秘患者比NOIC更易发生DD和更严重的便秘症状。
