“…Much of this has been made possible by the development of the technique of transcanalicular laser DCR (Narioka et al, 2008). On purpose to increase the success rate of the procedure, the use of silicone tubes in DCR is quite common (Bousch et al, 1994;Rosen et al, 1997), although its beneficial effects have not been proven unequivocally (Smirnov et al, 2008;Saiju et al, 2009;Feng et al, 2011). On the contrary, silicone intubation has its own set of complications, which includes the infective potential of these stents (Smirnov et al, 2008;Saiju et al, 2009;Feng et al, 2011;Allen et al, 1989).…”

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.

“…However, there are some controversies associated with this procedure in techniques with flaps, 14,15,22,23 and no study has verified the efficacy of stents in ex-DCR without flap anastomosis. Premature stent loss did not cause recurrence in the current study, and another study of ex-DCR without flap anastomosis without stent insertion also showed a success rate similar to that of the current study.…”

The aim of this study was to compare surgical outcomes of external dacryocystorhinostomy with or without double mucosal flap anastomosis. A retrospective chart review was performed for 205 sides of 178 patients diagnosed with nasolacrimal duct obstruction. Double-flap anastomosis was performed on 57 sides (double-flap group) and complete flap excision on 148 sides (no-flap group). Criteria for surgical success were defined as no or minimal intermittent epiphora and no reflux on lacrimal irrigation 12 months postoperatively. Consequently, surgery was successful for 53 sides (93.0%) in the double-flap group and 138 sides (93.2%) in the no-flap group. There was no statistically significant difference in success rate between the groups (P = 0.947, the Fisher exact probability test). This study demonstrated that external dacryocystorhinostomy without flap anastomosis had a surgical outcome similar to that of double-flap anastomosis.

“…Saiju and colleagues1 carried out a study to address the important issue of whether silicone intubation is necessary in external dacryocystorhinostomy (DCR) surgery. They concluded that DCR without silastic intubation is less expensive than DCR with silastic intubation in primary uncomplicated NLDO and has a similar success rate.…”
