摘　　要：本研究的目的为探讨肛提肌裂孔是否受分娩方式及第二产程的影响。选取产妇200例,其中剖宫产100例,阴道分娩100例,同时选取未生育的育龄女性100例作为对照组,采用三维超声观察三组研究对象肛提肌裂孔大小,计算肛提肌裂孔周径及面积。结果显示:阴道分娩组静息、Valsalva状态下肛提肌裂孔周径和面积明显高于剖宫产组与对照组(P<0.05);阴道分娩组第二产程>1 h产妇静息、Valsalva状态下肛提肌裂孔周径和面积明显高于第二产程≤1 h产妇(P<0.05);阴道分娩组总产程>12 h产妇静息、Valsalva状态下肛提肌裂孔周径和面积明显高于总产程≤12 h产妇(P<0.05)。阴道分娩及第二产程明显影响产妇肛提肌裂孔。The purpose of this study was to investigate whether the anal levator fissure was affected by delivery mode and second stage of labor. A total of 200 cases of women were selected, including 100 cases of cesarean section and 100 cases of vaginal delivery, 100 infertile women of childbearing age were selected as the control group. The size of levator ani hiatus was observed by three-dimensional ultrasound, and the peripheral diameter and area of levator ani hiatus were calculated. The results show that: the vaginal delivery group, the circumference and areas of levator ANI hiatus at resting and Valsalva were significantly higher than that of cesarean section group and control group(P<0.05). In vaginal delivery group, the circumference and area of levator ani hiatus at rest and in Valsalva statein the second stage of labor > 1 h were were significantly higher than those in the second stage of labor ≤ 1 h(P<0.05). In vaginal delivery group, the perimeter and area of levator ani hiatus in resting and Valsalva state in women with total stage of labor >12 h were significantly higher than those in women with total stage of labor ≤12 h(P<0.05). Vaginal delivery and second stage of labor significantly affected the levator ani hiatus.
