结肠慢运输型便秘病变肠段的定位研究

目的 通过全结肠腔内压力测定、结肠运输功能试验和术中探查三者相结合方法，对慢运输结肠段进行定位研究，以达到治疗结肠慢运输型便秘(STC)的目的。方法 21例STC手术患者中，12例采取三者相结合的方法对病变结肠段作出了较准确的定位，根据定位对4例施行了升结肠 横结肠切除，3例横结肠切除，5例横结肠 降结肠 乙结肠切除。结果 12例患者均达到治愈目的，无便秘复发、顽固性腹泻及明显腹胀。结论 全结肠腔内压力测定、结肠运输功能试验和术中探查三者相结合的方法对慢运输结肠段的定位有较好的指导意义。通过选择性结肠段的切除即可避免复发便秘和顽固性腹泻的发生，又可保留部分结肠生理功能。

The Location of Pathological Changed Intestinal Segment in Slow Transit Constipation

Objective To facilitate the treatment of STC by locating the pathology- changed colonic segment with the methods of intraluminal manometry of the colon, colon transport function test and intraoperative exploration. Methods 12 cases in 21 cases of STC operations, whose lesions were located with the 3 methods combined, underwent ascend-transverse colectomy in 4 cases, transverse colectomy in 3 cases, transverse-descending colectomy plus sigmoidectomy in 5 cases. Results All patients were cured . No refractory diarrhea, recurrent constipation and serious abdominal distention were found. Conclusion With the combined use of intraluminal manometry, colon transport function test and intraoperative exploration, the pathological changed colonic segment could be located. Selective colectomy could reserve part of the colon function while few refractory diarrhea and recurrent constipation were found.
