A comparative study of endoscopic silicone tube intubation and conventional blind silicone tube intubation in the treatment of chronic dacryocystitis / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To compare the costeffectiveness of two surgical approachesendoscopic silicone tube intubation(ESTI) and conventional blind silicone tube intubation(CBSTI),in the management of chronic dacryocystitis(CDC).METHODS There were 46 cases of CDC from the Third Affiliated Hospital of Sun Yat-sen University from 2014 to 2015.Randomly,22 CDC patients were included in ESTI,24 patients were performed CBSTI.We analyzed both the final success rate,operating time,intraoperative visual analogue scale(VAS) and the rate of post-operative complications,as well as the final therapeutic effect.RESULTS In ESTI group,17 cases were cured,5 cases were improved and 3 cases were invalid.The success rate was 88.00％.Correspondingly for CBSTI group,14 cases were cured,6 eases were improved and 5 cases were invalid,and the success rate was 80.00％.ESTI was better,but there was no significant in success rate between the two groups (x2=0.881,P=0.644).Besides,the operating time and intraoperative VAS score in ESTI group was (10.32±2.30)min and 2.02±0.86,and they were(25.32 ± 4.87)min and 4.11 ± 1.44 in CBSTI group.So ESTI was better than CBSTI(t=-13.918,P=0.000;t=-6.012,P=0.000).ESTI had fewer complications(x2=4.878,P=0.027).CONCLUSION Compared to CBSTI,ESTI is a minimally invasive and highly effective technique for the treatment of CDC.The visualization of nasal endoscopy is the optimization of CBSTI,and this method need to be popularization and application.
