摘要:
目的探讨新型暂时性贲门支架治疗实验性犬贲门失弛缓症的疗效和安全性,研究支架取出后不同随访时间点的贲门段食管组织病理学变化特征。方法采用苄基二甲基十四烷氯化铵(BAC)内镜下食管下括约肌(LES)内环周注射法,24条毕格犬成功建立实验性贲门失弛缓症模型,随机分为对照组和实验组,每组12条,分别植入普通食管支架和新型贲门支架;支架留置4d后取出。于造模前、造模后和支架取出后1周,1、3和6个月,对各实验犬作食管测压和计时食管钡剂造影(TBE)检查,并于支架取出后每一随访时间点各处死3条实验犬,取贲门段食管作病理学检查。结果支架植入、取出和随访检查均顺利实施。两组均未发生食管穿孔等严重并发症。组间比较显示实验组支架移位率较低(实验组1条,对照组5条);实验组LES静息压降低更显著(支架取出后6个月时,组间差异有统计学意义,P=0.027);实验组TBE0~5min乘积差更大(支架取出后3个月时,组间差异有统计学意义,P=0.009)。LES静息压组内多重比较显示实验组有效维持期更长。增殖细胞核抗原(PCNA)和α-平滑肌肌动蛋白(α-SMA)免疫组化标记染色均显示食管贲门段组织炎症反应在随访1个月时达峰值;Masson三色法染色显示胶原纤维增生指数于随访3个月时趋于稳定状态。结论本实验中,新型暂时性贲门支架治疗犬贲门失弛缓症在安全性和疗效方面均优于普通食管支架
