摘要
目的：探讨肛直肠压力在直肠癌术后的变化以及在肛门功能评价中的价值。方法：选择直肠癌低位前切除术（Ｌｏｗａｎｔｅｒｉｏｒｒｅｓｅｃｔｉｏｎ，ＬＡＲ）的病人３１例；腹会阴直肠癌切除、耻骨直肠肌成形、乙状结肠会阴造瘘术（Ａｂｄｏｍｉｎａｌｐｅｒｉｎｅａｌｒｅｓｅｃｔｉｏｎ，ＡＰＲ）的病人２５例，正常对照组１０４例。测定了肛管、直肠的静息压，肛管最大挤压压，直肠初感容量和直肠最大耐受量，直肠肛门抑制反射以及直肠顺应性。结果：ＡＰＲ术后肛管静息压和肛管最大挤压压明显低于正常对照组；直肠最大耐受量和顺应性与ＬＡＲ术后的每日大便次数呈负相关；与ＡＰＲ术后的肛门功能呈正相关。结论：肛管最大挤压压，直肠最大耐受量以及直肠顺应性是判断直肠癌术后肛门功能的主要参数。
Objective: Employment of anorectal manometry to evaluate anus functions after rectal cancer operation. Methods: 31 cases of rectal cancer operated on with low anterior resection, 25 cases with abdominal perineal resection and 104 normal persons were tested. The maximal squeezing pressure of the anus, the maximal tolerable volume of the rectum, the rectal compliance and the anorectal inhibitory reflex were determined with anorectal manometry. Results: The maximal squeezing pressure of the anus was significantly decreased as compared to that of the normal and the maximal tolerable volume of the rectum and the rectal compliance were in direct proportion to the anus function and in inverse proportion to the frequency of daily bowel movement. Conclusion: The maximal squeezing pressure of the anus, themaximal tolerable volume of the rectum and the rectal compliance are very important parameters to evaluate the anus functions after rectal cancer operation.
