为探讨血吸虫病直肠癌切除术后结肠袋状吻合的生理学特征。将 46例中段血吸虫病直肠癌切除患者随机分为 A、B 2组 ,A组行直接吻合术 ,B组行结肠袋状吻合术 ,对两组病例的新直肠的生理机能进行评估 ,其中包括实验室研究。结果显示两组病例术后其括约肌压力相似 ,B组病例术后直肠的顺应性得以恢复 ,其顺应性为 0 .2 96 (0 .2 2 4～ 0 .347) L / k Pa,然而 ,A组病例术后顺应性下降 ,顺应性为 0 .194(0 .112～ 0 .2 35 ) L / k Pa,两组比较顺应性差异非常显著 (P<0 .0 0 1)。多元回归分析提示新直肠的顺应性与有利的临床机能有关 ,而肛管运动与不利的临床机能有关。结肠袋状肛管吻合能恢复新直肠的顺应性 ,并且对直肠癌低位切除后维持其较好的生理机能非常重要
To investigate the physiological characteristics of colonic anastomosis after resection of schistosomiasis. Forty - six cases of schistosomiasis in rectal cancer patients were randomly divided into group A and group B. Group A received direct anastomosis and group B received colonic pouch anastomosis. The physiological functions of the new rectum in both groups were evaluated, including Laboratory research. The results showed that the sphincter pressure was similar in both groups, and the rectal compliance of group B was restored to 0.296 (0.224-0.347) L / kPa. However, The compliance of the patients in group A decreased and the compliance was 0.194 (0.122.225) L / kPa. The differences in compliance between the two groups were significant (P <0.01). Multivariate regression analysis suggested that the compliance of neo-rectum was associated with favorable clinical function, while anal canal exercise was associated with adverse clinical function. Anatomical pouch anal anastomosis can restore the compliance of the new rectum, and the resection of the rectal cancer to maintain its better physiological function is very important
