NCT06428266

Brief Summary

In Mexico, upper lacrimal duct obstruction (ULDO) is a common pathology, and the standard surgical treatment is closed dracryointubation. Based on statistics from our headquarters, in 30% of cases there is a failure of the technique and recurrence of symptoms due to associated complications. Because of this, the application of a self-stable bicananlicular intubation set is proposed. The aim of this study is to describe the difference in efficacy and complication rate between the application of the self-stable bicanalicular intubation set II (FCI) and closed dacryointubation in patients with ULDO .

Outcome Measures

Primary Outcomes (2)

  • Irrigation of tha lacrimal duct

    Irrigation of the lacrimal duct with saline solution to seek for permeability

    three and four months after the procedure

  • Epiphora

    evidence of epiphora as told by the subject

    one, three and four months after surgery

Secondary Outcomes (3)

  • Occurrence of epistaxis

    one, three and four months after surgery

  • Presence of extrusion of bicanalicular intubation tubes

    one, three and four months after surgery

  • How well is the positioning of the silicone tubes

    one, three and four months after surgery

Study Arms (2)

Closed dacryointubation

ACTIVE COMPARATOR

Patients undergoing conventional closed dacryointubation with Crawford's tube

Procedure: Closed dacryointubation

Bicanalicular Intubation

EXPERIMENTAL

Patients undergoing bicanalicular intubation with Self-Stable Intubation Set II FCI

Device: Bicanalicular intubation

Interventions

Placement of the bicanalicular intubation set at each lacrimal point and fixed by means of its flaps at the level of the opening of the lacrimal sac.

Bicanalicular Intubation

Placement of dacryointubation tube through the canaliculus until it reaches the medial wall of the lacrimal sac and then passed the nasolacrimal duct until it empties out at the level of the inferior meatus.

Closed dacryointubation

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients over 18 years of age
  • Patients with stenosis and incomplete obstruction of the upper lacrimal duct with epiphora \> 2 on the Munk scale who have not previously undergone surgery on the affected tear duct
  • Patients who may undergo general anesthesia and sedation
  • Patients who are able to present and continue follow-up for the duration of the study
  • Acceptance to participate in the study by signing an informed consent

You may not qualify if:

  • Patients with ocular surface involvement affecting the upper lacrimal duct, such as blepharitis with tear point epithelialization
  • Patients with lacrimal point malposition and/or eyelid malposition due to entropion or ectropion
  • Patients with congenital or acquired obstruction of the lower lacrimal duct
  • Patients with a history of facial paralysis
  • Patients with systemic inflammatory disease such as scarring pemphigoid or Steven Johnson
  • Patients in whom tumour involvement of the lacrimal duct is suspected
  • Patients with reflex tear hypersecretion due to ocular surface involvement or other causes.
  • Pregnancy and breastfeeding
  • Active infection, eye trauma, history of facial trauma with broken bones of the nose, or history of sinus surgery.
