Trabeculectomy is the most commonly used glaucoma filtration surgery for glaucoma in the world. Conventional trabeculectomy is prone to anesthesia-related complications intraoperative and operationrelated complications postoperative in PCACG treatment. Modified minimally invasive trabeculectomy maybe can reduce the incidence of complications.Methods: We conducted a prospective case series study and performed modified fornix-based trabeculectomy in 27 patients(30 eyes) under topical anesthesia; we then observed intraoperative anesthesia and cooperation ef ect, intraoperative and postoperative complications, preoperative and postoperative visual acuity, intraocular pressure(IOP), visual field, and the use of ocular hypotensive drugs. The patients were followed up for at least 12 months.Results: All operations were completed successfully with no intraoperative complications. All 27 patients(30 eyes) were followed up for at least 12 months. No significant decrease in visual acuity was observed at days 1 or 7 and at months 1, 3, 6, and 12 after operation; however, a signii cant decrease in IOP was observed at days 1 and 7 and at months 1, 3, 6, and 12 after operation. Moreover, no significant progression in visual field mean defect was observed at month 12 after operation, and the number of ocular hypotensive drugs required was significantly reduced at months 6 and 12 after operation. By month 12 after operation, the overall success rate was 93.33%(28/30).Conclusions: Modii ed minimally invasive trabeculectomy is safe and ef ective for the treatment of PCACG.展开更多

文摘目的:对经皮导管介入封堵术、直视修补术和经胸微创封堵术3种治疗小儿室间隔缺损(ventricular septal defect,VSD)的手术方式进行回顾性对比分析以有助于VSD手术方式的合理化选择。方法:2011年1月1日至2011年12月31日在我院分别行经皮导管介入封堵术(介入组,n=123)、直视修补术(直视组,n=104)和经胸微创封堵术(微创组,n=23)的VSD患儿共250例,比较3组的手术时间、输血量、术后机械通气时间、术后重症监护室(intensive care unit,ICU)监护时间、术后住院时间、成功率和并发症发生率。结果:直视组手术时间、输血量、术后机械通气时间、术后ICU监护时间、术后住院时间明显大于介入组和微创组(P<0.001)。介入组无需输血、机械通气和ICU监护;微创组手术时间和术后住院时间明显长于介入组(P<0.001)。3组手术成功率和主要并发症发生率比较无统计学差别(P>0.05)。结论:3种手术方式均是治疗VSD安全、有效的方法。应充分评估病情,根据不同的手术适应证选择合适的手术方式。
