OBJECTIVES
To investigate correlation between rectal wall thickness (RWT) and anorectal pressures, in obstructed defecation syndrome (ODS) patients caused by internal rectal prolapse.
METHODS
ODS patients and healthy volunteers (HVs) underwent 3D endorectal ultrasound (3D-EUS) and high-resolution anorectal manometry (HRAM); RWT, total rectal wall volume (TRWV), pushing endorectal pressure (PEP), recto-anal gradient were determined RESULTS: We enrolled 35 ODS patients and 25 HVs. Patients showed markedly decreased TRWV, PEP, and recto-anal gradient. Linear correlation was found between markedly reduced TRWV and markedly hypotonic PEP.
CONCLUSIONS
HRAM and 3D-EUS could be performed in ODS assessment, to better understand rectal function.
目的
探讨直肠壁厚度（RWT）与肛门直肠压力的相关性，以及直肠内套叠引起的出口梗阻型便秘（ODS）患者的相关性。
方法
ODS 患者和健康志愿者（HV）接受 3D 直肠内超声（3D-EUS）和高分辨率肛门直肠测压（HRAM）检查；测定 RWT、总直肠壁容积（TRWV）、推注内直肠压力（PEP）、直肠肛管梯度。
结果
共纳入 35 例 ODS 患者和 25 例 HV。患者的 TRWV、PEP 和直肠肛管梯度明显降低。明显降低的 TRWV 与明显低张力的 PEP 呈线性相关。
结论
HRAM 和 3D-EUS 可用于 ODS 评估，以更好地了解直肠功能。
