Abstract´╝Ü 目的: 探讨经腹吻合器门奇断流术对胃动力学的影响及术中行幽门成形术的意义.方法: 将肝硬化门静脉高压症模型犬18只,随机分为3组: A组: 经腹吻合器门奇断流术;B组: 经腹吻合器门奇断流术加幽门成形术;C组: 对照组即假手术组.分别于术前3 d、术后7、14及21 d采用单切面实时超声显像法行流体餐胃动力学多项指标检测.结果: A组术后7 d与术前相比,胃半排空时间、胃全排空时间明显延长,胃窦收缩频率、胃窦收缩幅度、胃窦运动指数明显下降(101.8±16.89 min vs 63.22±12.67 min,215.0±31.26 min vs 153.7±22.45 min,0.96±0.21vs 2.11±0.55,0.12±0.03 vs 0.20±0.04,0.17±0.05 vs 0.47±0.13,均P<0.05),术后14 d除胃窦收缩频率外,其他各项胃动力学指标已恢复至术前水平.术后21 d时胃窦收缩频率与术前相比,差异无显著性.B组术后7 d与术前相比,胃半排空时间、胃全排空时间差异无显著性,胃窦收缩频率明显下降(0.91±0.38 vs 2.04±0.49,P<0.05),但与A组差异无显著性.术后21 d胃窦收缩频率与术前相比,差异无显著性.C组术后7 d各项胃动力学指标已恢复至术前水平.结论: 门静脉高压症犬行经腹吻合器门奇断流术中附加幽门成形术仅在术后1 wk内改善胃排空状况,经腹吻合器门奇断流术可不必常规行幽门成形术.
