STARR术治疗直肠前突后肛肠动力学变化的研究

Changes of Anorectal Dynamics in Rectocele after STARR

为研究运用经肛门吻合器直肠切除术（STARR）治疗直肠前突的临床疗效，对采用STARR术治疗直肠前突的50例患者（治疗组）手术前后行肛管直肠测压，将肛管舒张压、肛管最大收缩压、模拟排便时直肠压力和直肠静息压分别与正常对照组100名进行比较。结果显示，治疗组50例患者均治愈出院，术前患者肛管舒张压、直肠静息压和模拟排便时直肠压力较正常对照组明显降低（P〈0．05）；术后患者肛管舒张压、直肠静息压和模拟排便时的直肠压力与正常对照组比较无统计学意义（P〉0．05）。结果表明，运用STARR术治疗直肠前突是一种有效的手术方法。

In order to study the clinical efficacy of stapled transanal rectal resection （STARR） in treating rectocele,50 cases （treatment group） to be subjected to STARR were measured for anorectal pressure pre-operatively and postoperatively. Anal canal diastolic pressure, maximum anal canal systolic pressure, rectal pressure during simulated defecation and rectal rest pressure in treatment group were compared with those in control group （100 normal healthy subjects）. The results showed that all 50 cases in treatment group were cured and discharged from hospital;Anal canal diastolic pressure, rectal rest pressure and rectal pres- sure during simulated defecation were significantly lower in treatment group than in the controls before surgery（ P〈0.05） ;after surgery, anal canal diastolic pressure, rectal rest pressure and rectal pressure dur-ing simulated defecation showed no statistical differences （ P〉0.05）. It is concluded that STRR is an ef-fective method for rectocele.
