RESUMEN
@#AIM: To investigate the effect and safety of endoscopic-assisted RS silicone intubation for congenital nasolacrimal duct obstruction after failed probing in children, in order to guide the clinical application.<p>METHODS: Retrospective case series. Totally 158 children(158 eyes)with congenital nasolacrimal duct obstruction who were failed probing in our hospital from September 2016 to September 2019 were selected as the research subjects. All patients underwent endoscopic-assisted RS silicone intubation. Regular follow-up was performed 1, 3, and 6mo after surgery. Observe the children's gender, age, treatment history, presence or absence of discharge before surgery; treatment effect; complications; types of nasolacrimal duct obstruction. Spearman's correlation coefficient calculation and analysis of the relationship between ages, times of probing and operation efficiency, Fisher's exact probability test for the operation efficiency of different types of nasolacrimal duct obstruction, and chi square test for the operation efficiency of presence or absence of discharge.<p>RESULTS: The total effective rate was 89.9%(142/158). The effective rate of surgery tends to decrease with age(Spearman's correlation coefficient <i>rs</i>= -1.000, <i>P</i><0.01). The effective rate of surgery showed a downward trend with the increase of the times of probing(Spearman's correlation coefficient <i>rs</i>= -1.000, <i>P</i><0.01). The efficiency of membranous nasolacrimal duct obstruction surgery is higher than that of complex nasolacrimal duct obstruction, and the difference is statistically significant(<i>P</i><0.05). It cannot be considered that there is a statistically significant difference in the effectiveness of the operation between the two symptoms with or without discharge(<i>P</i>>0.05). The main complications were: false passage formation(16 eyes, 10.1%), loss of tube(14 eyes, 8.9%), red eyes and irritated tears(18 eyes, 11.4%), punctums tissue adhesion(3 eyes, 1.9%), punctum granuloma formation(1 eye, 0.6%).<p>CONCLUSION: Endoscopic-assisted RS silicone intubation has a higher effective rate and better safety in the treatment of congenital nasolacrimal duct obstruction after failed probing in children. The effective rate of surgery decreases with age, and decreases with the increase of the times of probing. Membranous nasolacrimal duct obstruction is more effective than complicated nasolacrimal duct obstruction.
RESUMEN
Purpose: The purpose of this study is to evaluate the effectiveness of chronic suppurative lacrimal canaliculitis treatment using chalazion forceps. Patients and Methods: A prospective study was performed on consecutive patients who accepted the aid of chalazion forceps to treat chronic suppurative lacrimal canaliculitis. Two different treatment methods using chalazion forceps were performed according to the degree of lacrimal canaliculitis. Postoperatively, the patients received 0.5% levofloxacin eye drops four times per day and 0.5 g oral levofloxacin tablets once per day for 4 days. The follow‑up period was more than 3 months. Lacrimal irrigation, the condition of the lacrimal punctum, and patients’ symptoms were carefully evaluated. Results: In total, 32 patients met the criteria for chronic suppurative lacrimal canaliculitis. Included were 6 males and 26 females. Their average age was 51.7 ± 14.9 years (range; 19–80 years), and all had unilateral canaliculitis. The mean duration of the symptoms was 18.9 ± 9.8 months (range; 3–48 months). The mean follow‑up time was 14.7 ± 7.8 months. The signs and symptoms resolved completely in all patients within 15 days, and no recurrence was observed. No patients reported epiphora after the treatment. Conclusions: The use of chalazion forceps is effective in treating chronic suppurative lacrimal canaliculitis. The forceps may offer an alternative treatment technology in the management of suppurative lacrimal canaliculitis.
RESUMEN
To evaluate the value of silicone intubation and ring-fixed method in canalicular laceration. ●METHODS: A retrospective study of 36 cases with laceration of lacrimal canaliculus. For all the patients, microscope was used to find the broken ends of the lacrimal canaliculus, and then straight insertion was performed to the distant and near broken ends through the upper and lower lacrimal points, then passed the dacryocyst to insert nasolacrimal canal and ended up in inferior nasal meatus. Thus, clinical data about forming annular support to treat laceration of lacrimal canaliculus was presented here. ● RESULTS: All 36 patients with traumatic canalicular laceration were anastomosed successfully and all patients healed without infection. The surgery went well, intubation was smoothly, all patients were followed - up for another 6mo after the stent was removed. The accidental fall off of the stent was not observed during the follow - up. During the follow - up 10 - 18mo after extubation, when the stent was removed, 32 cases (88. 9%) recovered to normal lacrimal drainage function;4 cases ( 11. 1%) remained epiphora with obstructed lacrimal passage. All cases were no lower eyelid ectropion. ●CONCLUSlON: For the patients with inferior canalicular laceration, the silicone intubation and ring-fixed method is effective, low irritation and less complication.
