Silicone Intubation

Introduction: Intubation in primary transcanalicular laser assisted dacryocystorhinostomy (TCLADCR) is performed to increase the success rates. However, the associated inflammation and infection can have adverse effects. Objective: To study the microbial infection and drug susceptibility of extubated silicone tubes and final anatomical patency in patients undergoing TCLADCR. Materials and methods: A non-randomised prospective interventional study was conducted in a tertiary care eye centre. The study included twenty consecutive adult patients with primary nasolacrimal duct obstruction. They underwent TCLADCR with bicanalicular silicone intubation. The stents were removed at 2 months and subjected to culture sensitivity, followed by administration of appropriate antimicrobial agents. Main outcome measures studied were the microbial spectrum on the cultured tubes, their sensitivity profile and its correlation with final anatomical patency. Results: A positive culture was obtained in 100% cases, comprising of normal commensals and pathogenic organisms. Of the total 24 isolates, 16 (66.6%) Gram positive bacteria (75% Staphylococcus aureus) and 8 (33.3%) Gram negative bacteria (commonest E.coli) were found, with 4 tubes having more than one isolate. No fungal growth was seen. Ninety percent success rate was achieved at one year following appropriate antimicrobial therapy except in 2 patients with gram negative isolates who had failed to take the prescribed antibiotics following sensitivity reports. There was no correlation between multiple infections and success rate. However, by using the Fisher exact test, a positive correlation was obtained between appropriate antibiotic treatment and the final anatomical patency (p<0.05). Conclusion: Silicone intubation predisposes to microbial growth, which if neglected, can lead to failure of TCLADCR.

Purpose. To compare the success rate and complications of pulled versus pushed monocanalicular intubation in adults with incomplete lacrimal drainage system obstruction (lacrimal drainage system stenosis). Methods. Patients with lacrimal drainage system stenosis (Munk grade ≥3), including both nasolacrimal duct (NLD) stenosis and common canalicular stenosis, were recruited in this prospective comparative case series. Patients underwent probing and either Monoka (51 eyes) or Masterka (48 eyes) intubation under general or local anesthesia. Tubes were removed 4–14 weeks after the procedure. Six months after tube removal, Munk grades 0 and 1 were defined as a complete success, Munk grade 2 was defined as a partial success, and Munk grade ≥3 was defined as failure. All complications were recorded. Results. Ninety-nine eyes from 89 patients with lacrimal drainage system stenosis who underwent either Monoka (51 eyes) or Masterka (48 eyes) intubation were included. The mean (SD) age of the patients was 55.4 (12) years in the Monoka group and 53.5 (12.9) in the Masterka group. Groups were matched on demographics. Masterka intubation could not be performed in one eye. Complete and partial successes were observed in 52.9% (27/51) and 17.6% (9/51) of eyes in the Monoka group and 42.6% (20/47) and 12.8% (6/47) of eyes in the Masterka group, respectively ( p = 0.29 ). There was a trend toward a higher total success rate in patients with NLD stenosis treated with Monoka 66.7% (26/39) than Masterka 45.5% (15/33) intubation ( p = 0.07 ). This trend also existed in patients with common canalicular stenosis (83.3% (10/12) vs. 76.6% (11/14), p = 0.75 ). Age, sex, bilateral involvement, and duration of intubation did not have a significant impact on the success rate. Early tube loss, slit puncta, and temporary superficial punctate keratopathy were observed complications. Conclusion. Intubation with the pulled monocanalicular silicone tube was associated with a slightly but not significantly higher success rate in adults with lacrimal drainage system stenosis. Patients with NLD stenosis may achieve better results with pulled silicone tubes.

Lacrimal Drainage

Silicone tubing was used to repair the patency of the nasolacrimal drainage system in 115 patients (four bilaterally) with chronic nasolacrimal duct obstruction. The patients were over 20 years old and 16 were men and 99 women; 46% presented an uncomplicated obstruction with epiphora and 54% presented additional signs of chronic dacryocystitis. We used the technique of Quickert and Dryden with modifications. The silicone tube remained for a mean of 5.5 months (± 2.5 SD). After removal of the tube the follow-up ranged from 6 to 42 months (mean ± SD: 16 ± 9). Patency was maintained in 89% of cases with uncomplicated obstruction and in 69% of those with chronic dacryocystitis (total success rate 78%). We can therefore recommend silicone intubation of the lacrimal drainage system as an alternative to dacryocystorhinostomy (DCR), in adults with obstruction of the nasolacrimal duct. In addition, unlike DCR this technique is bloodless and the operation takes less time.

Purpose:  To study the effect of Triamcinolone Acetonide injection into the ostium through the external wound after one week of external Dacryocystorhinostomy. Study Design:  Quasi experimental study. Place and Duration of Study:  Khalid Eye Clinic, Karachi, from July 2018 to June 2019. Methods:  This study included forty patients with age ranging between 18 to 36 years. All patients had obstruction of the nasolacrimal duct. Patients were categorized into two groups. Both groups underwent external dacryocystorhinostomy with silicone intubation, with the difference being that patients in group A were injected with 20 units of Triamcinolone acetonide 40 mg/ml into the ostium through wound using 27 gauge needle, one week after the surgery. Group B did not receive any injection. Both groups were followed for a period of four months, at which time the silicone tube was removed and patency of lacrimal system was ascertained via syringing with balanced salt solution through the lacrimal puncta. Main outcome measure was the success rate of procedure. Results:  The mean age of the patients was 27.1 ± 5.48 years. Success rate was 100% among the patients of group A and 85% in the patients of group B at the end of the four months followup period. However, the results were statistically insignificant (p = 0.115). Conclusion:  Although statistically insignificant but clinically Triamcinolone Acetonide proved helpful in reducing fibrosis and ostium granuloma formation in patients with Ex-DCR. Thus preventing failure of external Dacryocystorhinostomy. Key Words:  Triamcinolone acetonide, external dacryocystorhinostomy, DCR.
