不同防粘连剂在输卵管介入再通术中预防术后再粘连的对比研究

目的 探讨不同防粘连剂在输卵管介入再通术中预防术后再粘连的临床价值.方法 将508例输卵管阻塞患者随机分为对照组(245例)、几丁糖组(108例)、透明质酸钠组(113例)、碘油组(42例).对照组输卵管介入再通术后输卵管内灌注松解液,其他组输卵管介入再通术后输卵管内分别注入几丁糖、透明质酸钠、碘油,每侧输卵管注入量均为2～3 ml.术中观察输卵管阻塞的部位、介入再通率,术后3个月随访各组患者输卵管通水通畅率,术后12个月随访妊娠率.结果 508例共计1016条输卵管,其中峡部阻塞输卵管330条,间质部阻塞输卵管563条,因异位妊娠切除输卵管37条,输卵管通畅86条.(1)介入再通率:几丁糖组、透明质酸钠组、碘油组及对照组输卵管介入再通率分别为95.7%(179/187),97.9%(191/195),98.7%(75176)和97.7%(425/435),各组分别比较,差异均无统计学意义(P＞0.05);(2)术后3个月输卵管通水通畅率:术后3个月输卵管通水通畅率几丁糖组(91.7%,99/108)、透明质酸钠组(88.5%,100/113)通畅率明显高于碘油组(71.4%,30/42)和对照组(74.3%,182/245),差异有统计学意义(P＜0.05);(3)术后12个月妊娠率:术后12个月内妊娠率几丁糖组(48.1%,52/108)、透明质酸钠组(41.6%,47/113)高于碘油组(23.8%,10/42)和对照组(24.1%,59/245),差异也有统计学意义(P＜0.05).结论 几丁糖和透明质酸钠均能有效地减少输卵管介入再通术后输卵管再粘连的发生,提高妊娠率.

Comparative study on different anti-adhesion agents in preventing tubal obstruction after interventional recanalization

Objective To study the efficacy of different anti-adhesion agents used in preventing tubal obstruction after recanalization.Methods Five hundred and eight patients with tubal obstruction were divided into 245 cases in control group,108 cases in chitosan group;113 cases in sodium hyaluronate group and 42 cases in lipiodol group.The patients in control group were injected with anti-inflammation agents after recanalizatian,while other groups were injected with chitosan,sodium hyaluronate or lipiodol at dose of 2-3 ml in every therapeutic group.The rate of location of tubal obstruction and tubal recanalization were recorded during operation.Then patients in every group were followed up on tubal patency after 3 months,and pregnancy rate after 12 months.Results Among 1016 fallopian tubes in 508 patients,there were 330 tubes occlusion at isthmus portion and 563 tubes occlusion at interstitial portion of fallopian tube.Thirtyseven fallopian tubes were ablated because of ectopic pregnancy,86 fallopian tubes were unobstructed.(1)The recanalization rate were 95.7% (179/187) in chitosan group,97.9% (191/195) in sodium hyaluronate group,98.7% (75/76) in lipiodol group and 97.7% (425/435) in control group,which did not show statistical difference (P＞0.05).(2) The rates of tubal patency after 3 months of 91.7% (99/108) in chitosan group and 88.5% (100/113) in sodium hyaluronate group were significantly higher than 71.4% (30/42) in lipiodol group and 74.3% (182/245) in control group (P ＜0.05).(3)The rates of intrauterine pregnancy after 12 months were 48.1% (52/108) in chitosan group and 41.6% (47/113) in sodium hyaluronate group,which were significantly higher than 23.8% (10/42) in lipiodol group and 24.1% (59/245) in control group (P ＜ 0.05).Conclusion Chitosan and sodium hyaluronate could be effective to prevent tubal obstruction after interventional recanalization and increase pregnancy rate.
