研究目的:

肛门直肠狭窄是指肛管或直肠的腔道直径变小、狭窄,使粪便通过受阻、排出困难的一类疾病。目前临床中多见因肛门部手术操作不当造成的医源性肛门狭窄。据国外报道混合痔外剥内扎术引起肛门狭窄的发生率为2.9%,而PPH术后直肠狭窄的发生率大概为0.8%~2.5%。随着肛肠疾病发病率的不断提升,医源性狭窄所占的比例逐年升高,严重影响患者的生存质量。 目前,传统手术方式治疗肛门直肠狭窄难以达到预期临床疗效。前期药效学试验表明,芍倍注射液有明显抗急性渗出性炎症及慢性增生性炎症作用、一定的体外抑菌作用。同时,临床观察初步证实,纵切横扩瘢痕松解结合芍倍封闭术治疗肛门直肠狭窄疗效显著。鉴于此,本研究一方面通过前瞻性、多中心、随机对照试验设计,以随访明确远期效果,对围手术期患者疼痛、出血、狭窄缓解程度等发生率进行统计,明确本疗法的总体疗效。另外,本研究通过动物实验观察瘢痕组织内炎性细胞水平,采用免疫组化观察瘢痕病理组织形态变化情况,使用RT-PCR及Western blot法检测TGF-β1、Smad3的mRNA和蛋白表达情况,进一步研究芍倍注射液减轻炎症刺激、软化瘢痕的具体机制。

Objectives of Study:

Anorectal stenosis refers to a kind of disease in which the diameter of the anal canal or rectal cavity becomes smaller and narrower, which makes the passage of feces blocked and the excretion difficult. At present, iatrogenic anal stenosis caused by improper operation of anal surgery is common in clinic. According to foreign reports, the incidence of anal stenosis caused by external stripping and internal ligation of mixed hemorrhoids is 2.9%, while the incidence of rectal stenosis after PPH is about 0.8% ~ 2.5%. With the increasing incidence rate of anorectal diseases, the proportion of iatrogenic stenosis is increasing year by year, which seriously affects the quality of life of patients. At present, the traditional surgical treatment of anorectal stenosis is difficult to achieve the expected clinical efficacy. Preliminary pharmacodynamic tests showed that Shaobei injection had obvious anti acute exudative inflammation and chronic proliferative inflammation, and certain antibacterial effect in vitro. At the same time, clinical observation has preliminarily confirmed that longitudinal and transverse dilatation scar release combined with Shaobei closure is effective in the treatment of anorectal stenosis. In view of this, this study, on the one hand, through a prospective, multicenter, randomized controlled trial design, to follow-up to determine the long-term effect, and to make statistics on the incidence of pain, bleeding, stenosis relief and so on in perioperative patients, so as to determine the overall efficacy of this therapy. In addition, the level of inflammatory cells in scar tissue was observed through animal experiments, the morphological changes of scar tissue were observed by immunohistochemistry, and TGF was detected by RT-PCR and Western blot- β 1. To further study the specific mechanism of Shaobei injection in reducing inflammatory stimulation and softening scar.
