Follow up of Nasolacrimal Intubation in Adults - Full Text View

Purpose

For patients with chronic epiphora, Dacryocystorhinostomy is currently the gold standard treatment, with a success rate of 80-90% according to literature. Another available treatment, which is far less used, in nasolacrimal intubation, using a silicone tube.

In our study, we would like to find the efficacy of nasolacrimal duct intubation, which was performed in our medical center on a few hundred patients with mild epiphora.

Study hypothesis: nasolacrimal intubation in adults, with a clinically mild epiphora, is close in it's efficacy to the Dacryocystorhinostomy procedure.

Further study details as provided by Shaare Zedek Medical Center:

Primary Outcome Measures:

Patient being completely free of tearing. [ Time Frame: 1 year. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Following nasolacrimal intubation, did the patient need a Dacryocystorhinostomy surgery. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Enrollment:	180
Study Start Date:	January 2000
Primary Completion Date:	December 2007 (Final data collection date for primary outcome measure)

Groups/Cohorts	Assigned Interventions
Primary All the patients in our medical center who underwent nasolacrimal intubation, due to mild epiphora, during the years 2000-2007.	Device: Silicone tube Silicone tube which is inserted into the tear duct through the punctum in the eyelid, then passed through the tear duct till it enters the nose and secured in place using a surgical knot. The tube remains in place for 3-6 months, than take out by the surgeon.

Detailed Description:

Under normal conditions, the amount of tears excreted from lacrimal glands to the eye is equal to the amount drained through the tear duct. Epiphora in adults usually involves a blockage of the lacrimal sac or the nasolacrimal duct. Epiphora causes tearing in patients, which can be treated sympthomatically in a conservative way (antibiotic treatment, probing of the tear duct, pressure irrigation of the tear duct) or therapeutic in an invasive way. The invasive treatment includes one of the following:

Dacryocystorhinostomy - surgery for reconstructing an alternative path for tear drainage.
Nasolacrimal intubation - inserting a silicone tube through the tear duct. The tube is usually removed after 3-6 months.

Currently, there are only a few reports regarding the efficacy of nasolacrimal intubation, all with a small number of research subjects. Also, these reports have stratified the patients according to the location of the tear duct blockage, and didn't take into account the severity of the blockage (ie the severity of symptoms) prior to performing the intubation.

In our research, we would like to find the efficacy of nasolacrimal intubation which was performed in our medical center on a few hundred patients with mild epiphora, and to compare in with the efficacy of the Dacryocystorhinostomy - which is 80-90% according to literature.
