Abstract
Purpose: To compare the success rates between silicone tube intubation using a lacrimal endoscope and using a conventional nasal endoscope alone in adult patients suffering from epiphora. Methods: We conducted a retrospective chart review of 80 eyes of 55 patients who underwent silicone tube intubation from January 2014 to June 2017. Patients were preoperatively diagnosed with syringing and dacryocystography. The silicone tube was removed 3 months after surgery and success rates were evaluated at 4 and 12 months. Success rates were analyzed by dividing the patients into two groups, according to lacrimal endoscope use. Results: A lacrimal endoscope was used in 40 eyes. In the group using a lacrimal endoscope, preoperative diagnoses were partial obstruction in 26 eyes and complete obstruction in 14 eyes. In the group without lacrimal endoscope use, preoperative diagnoses were partial obstruction in 35 eyes and complete obstruction in 5 eyes (p = 0.018). The success rates at 4 and 12 months after surgery in the two groups (with and without lacrimal endoscope use) were 87.5% and 80.0% and 72.0% and 62.1% (p = 0.546 and p = 0.565), respectively. The success rates of patients with partial obstruction in the two groups were 92.3% and 82.9% at 4 months and 71.4% and 69.2% at 12 months (p = 0.448 and p = 1.000), respectively. The success rates of patients with complete obstruction in the two groups were 78.6% and 60.0% at 4 months and 72.7% and 33.3% at 12 months (p = 0.570 and p = 0.505), respectively. Site differences, the degree of obstruction, and lacrimal endoscope use had a significant impact on the success rate at 4 and 12 months (p = 0.001 and p = 0.022, respectively). Conclusions: Although silicone tube intubation using a lacrimal endoscope cannot guarantee a significant success rate, it is possible to observe the anatomical structure of the nasolacrimal pathway in real time, such that the appropriate diagnosis and treatment can be performed simultaneously. Because patients diagnosed as having a complete obstruction had a good success rate, we can extend indication of silicone tube intubation as a less invasive approach.
목적: 눈물길미세내시경을 이용한 실리콘관삽입술과 기존의 코내시경만으로 시행한 방법 간의 성공률을 비교하고자 하였다. 대상과 방법: 2014년 1월부터 2017년 6월까지 본원에서 실리콘관삽입술을 시행한 환자들을 대상으로 하였다. 술 전 눈물소관 관류검사와 눈물주머니조영술로 진단하였다. 술 후 3개월 때 실리콘관을 제거하였고 4, 12개월 때 성공률을 내시경 사용에 따라 두 군으로 나눠 분석하였다. 결과: 총 55명, 80안으로 술 전 진단에서 사용군은 부분폐쇄 26안, 완전폐쇄 14안, 미사용군은 부분폐쇄 35안, 완전폐쇄 5안이었다(p=0.018). 술 후 4, 12개월 때 성공률은 사용군에서는 87.5%, 80.0%, 미사용군에서는 72.0%, 62.1%였다(p=0.546, p=0.565). 부분폐쇄에서 사용군과 미사용군의 성공률은 4개월 때 92.3%, 82.9%, 12개월 때 71.4%, 62.9% (p=0.448, p=1.000), 완전폐쇄에서 성공률은 4개월 때 78.6%, 60.0%, 12개월 때 72.7%, 33.3%였다(p=0.570, p=0.505). 눈물길미세내시경의 사용과 폐쇄의 위치 및 정도의 차이가 술 후 4, 12개월 때 성공률에 유의한 영향을 미침을 확인하였다(p=0.001, p=0.022). 결론: 눈물길미세내시경을 이용한 실리콘관삽입술은 기존의 것에 비하여 성공률이 유의하게 높지는 않았으나, 코눈물길의 구조를 실시간으로 확인하여 적절한 진단 및 치료가 동시에 가능하다. 완전폐쇄로 진단되었던 환자들에게도 좋은 성공률을 보여 그 적용 범위를 확대시켜 비침습적인 치료를 시행할 수 있을 것이다.
