目的：探讨完善泪道成形+义管植入日间手术患者的延续性护理对预防义管意外脱管的重要作用。方法：收集我科2016年1月至12月实施了标准延续性护理的泪道成形+义管植入日间手术患者的意外脱管情况。结果：泪道成形+义管植入日间手术患者随访期间没有发生医源性脱管，有9例9眼带管期间在院外发生脱管，意外脱管率为2.6%。结论：做好泪道成形+义管植入日间手术患者的延续性护理，有效降低义管意外脱出率，有利于患者康复。

Objective: To explore the important role of continuous nursing of the patients with day surgery of lacrimal duct forming combined tube implantation in the aspect of accident prevention to take off the tube. Methods: The information of the patients from Jan. to Dec. 2016 with accident the tube’s takeoff after carrying out the standard continuity of care were collected. Results: There was no iatrogenic but 9 eyes of 9 patients accidentally take off the tube during follow-up period. Accidental decannulation rate was 2.6%. Conclusion: Continuous care of the patients with day surgery of lacrimal duct forming combined tube implantation can effectively reduce the tube accidentally removal rate and be beneficial to patients’ recovery.

目的：探讨改良的外路泪囊鼻腔吻合术式联合泪道置管治疗泪囊黏液囊肿的临床疗效。
方法：对23例（23眼）泪囊黏液囊肿行改良式泪囊鼻腔吻合术，并联合泪道置管，术后行泪道冲洗，并观察泪溢情况。

结果：23例患者，1例术中改为泪囊摘除术，20例完成12个月的追踪观察治疗，1例术后6个月失访，1例12个月时失访。随访1个月，22例患者术后泪囊肿均消失，外观明显改善；随访12个月，20例患者中18例溢泪症状完全消失，所有患者泪道冲洗通畅，仅1例患者因泪溢症状对手术疗效不满意。

结论：改良式外路泪囊鼻腔吻合术联合泪道置管治疗泪囊黏液囊肿，具有良好的临床效果值得推广。

Purpose: To investigate the eficacy of modified external dacrocystorhinostomy (DCR) with intubation in the treatment of lacrimal sac cys.

Methods: Twenty-three lacrimal sac cyst cases (23 eyes) were enrolled and treated with DCR technique and tube intubation. The success was assessed based on lacrimalirrigation and symptomatic relief of epiphora.

Results: Among 23 patients, surgery was intenupted and converted to dacryocystectomy in l case, thus surgery was successfully performed in 22 cases. Among them, 1 case lost follow up at 6 month, 1 case lost follow up at 12 month. At 1 month visit, lacrimal sac cyst disappeared in 22 cases. At 12 month visit, epiphora was completed relieved in 18 out of 20 cases, irrigation indicated no obstruction in all 20 cases.

Conclusions :The modified DCR technique with intubation has satisfactory outcome for lacrimal sac cyst.
