  • 简介:甲状腺癌临床上常见恶性肿瘤,约占全身肿瘤1,3%,占头颈部肿瘤5.1%。病理类型分为乳头状腺癌(60%~80%)、滤泡状腺癌(20%)、髓样癌(3%-10%)及未分化癌(15%)。分化型甲状腺癌包括乳头状腺癌滤泡状腺癌,发病率高,生长缓慢,恶性程度较低。由于基层医院在术前诊断方面的欠缺,术中往往没有冷冻病理检查,造成手术不规范,需要再次手术修正。现我院52例需再次手术分化型甲状腺癌病例进行分析,总结如下。

  • 简介:目的探讨小梁切除术中连续锁边缝合两种不同结膜瓣泪膜稳定性影响。方法双眼原发性青光眼患者26例,双眼均行小梁切除术,左眼组:以穹窿部为基底结膜瓣组26例26眼;右眼组:以角膜缘为基底结膜瓣组26例26眼,两组中结膜瓣均采用连续缝合密闭切口,并检测术前1d、术后1d、7d、14d、30d、60d泪膜破裂时间(BreakupTime,BUT)、基础泪液分泌试验(SchirmerItest,SIT)、角膜荧光素染色积分(fluorescenceintegral,FI)。结果两组间BUT、SchirmerI试验于术后1d、7d、14d、30d及60d比较差异均有统计学意义(均P0.05)。结论连续锁边缝合以穹窿为基底结膜瓣小梁切除术显著降低了泪膜稳定性,为提高患者舒适度我们主张以角膜缘为基底作为手术切口。
