Optimizing clinical outcomes for endoscopic lacrimal duct recanalization in patients with complete PANDO

Abstract

The study aims to describe modi cations and re nements in the technique and technology of Transcanalicular Endoscopic Lacrimal Duct Recanalization (TELDR) based on anatomical foundations to optimize its clinical outcomes in patients with complete Primary Acquired Nasolacrimal Duct Obstruction (PANDO). MethodsThe medical records of 115 patients who underwent Transcanalicular Endoscopic Lacrimal Duct Recanalization procedures from January 2018 to July 2020 were reviewed retrospectively. Of the 115 patients, only those 35 patients with complete PANDO characterized by longstanding epiphora of 5-7 years duration, dense, diffuse brous tissue obstruction involving the sac, sac duct junction and the entire length of the nasolacrimal duct were included in the study. Parameters for success were analyzed based on patency on irrigation, functional endoscopic dye test, and improvement of epiphora. ResultsForty-ve cases from 35 patients with complete PANDO were included in the study. The mean length of time from the date of operation to silicone stent removal was 8.1 weeks while the mean length of followup starting from the removal of silicone stent to last follow-up was 61.0 weeks. There were 95.6% anatomic patency on canalicular irrigation with saline and 95.6% functional patency based on functional endoscopic dye test. There was signi cant improvement of epiphora (p-value of < 0.0001) postoperatively. ConclusionThe results of modi ed TELDR improved clinical outcomes and could be a de nitive treatment in patients with complete PANDO with longstanding, dense, diffuse, brous tissue obstruction. Patients who experience reobstruction, may undergo a repeat of the recanalization approach.

Clinical Implication of Dacryoendoscopy in the Patients with Tearing: A Systematic Review

“…Conventional nasal endoscope or nasal examination is still effective for the detection of submucosal insertion, since it enables detection of the direction and site of submucosal insertion at the sac and NLD [ 59 ]. Recently, DE-assisted recanalization and balloon dilatation of the NLD using the Ophtacath Lacrimal Duct Balloon Catheter (FCI Ophthalmics) were reviewed with 95.6% anatomic and functional patency test in 115 patients [ 60 ].…”

Long-term outcomes of laser dacryoplasty combined with intubation using a new silicon tube in patients with lacrimal duct obstruction

“…It may inspire future tube design. Limitations of this retrospective observational study include the absence of a control group in which another surgery was used [44][45][46][47][48][49][50][51] . Intubation was only performed in complicated cases and postoperative care varied among different cases, which limited the comparison.…”

Morphometric and morphological evaluation of the nasolacrimal groove in 150 dry bones in the Anatolian population

“…Although various attempts at nasolacrimal duct recanalization and subsequent intubation with less invasive alternatives have been made over the last twenty years, considerable work has to be done before they can match the success rates of dacryocystorhinostomy surgeries [13].…”
