Monocanalicular Intubation

Abstract Introduction The LacriJet (FCI S. A. S. – France Chirurgie Instrumentation, Paris, France) represents a novel, simplified and preloaded system for monocanalicular or monocanaliculonasal nasolacrimal duct intubation. It is a further development of the Masterka and shall reduce the intubation time during the surgical procedure. The aim of the present study was to present first experiences with this system for different indications. Material and Methods All patients who underwent nasolacrimal duct intubation with the LacriJet at the University of Muenster Medical Center in the period from March to November 2019 were included. The postoperative outcome was evaluated 3 to 6 months later. Results In total, 12 nasolacrimal duct intubations with the LacriJet were performed at our center in the above-mentioned period. The main indication for intubation was congenital nasolacrimal duct obstruction (CNLDO). In addition, intubation was performed in cases with eye lid tumors involving the nasolacrimal duct, in a case of canalicular laceration and in a case of canaliculitis. In 3 cases, there was an early dislocation or a complete loss of intubation. Of these, 2 were cases with CNLDO and the third dislocation was due to manipulation by the patient. All in all, the functional results were satisfying. Summary The use of the LacriJet is highly suitable for the treatment of CNLDO, stenting in canalicular laceration or lid tumours involving the lacrimal drainage system. However, the known disadvantages of monocanalicular intubation (dislocation, early loss of intubation) also occur with this type of system and a system briefing seems useful. The LacriJet therefore represents a modern and simple method for nasolacrimal duct intubation and can be used for various indications.

Purpose: Sialoendoscope was used as a dacryoendoscope, high- definition images of the lacrimal drainage system (LDS) were captured and its performance in congenital nasolacrimal duct obstruction (CNLDO) is reported. Methods: Nasal endoscopy was done as the first in all the cases using a 0°, 2.7 mm nasal endoscope (Karl Stroz Tutlingan Germany). This was followed by Dacryoendoscopy (DEN) of the lacrimal drainage system from puncta till the valve of Hasner. DEN was performed under general anaesthesia in 26 children (including 17 primary and 9 failed probing cases). All cases were examined using 0.8 mm sialoendoscope (Karl Storz, Tuttlingen, Germany) with fibreoptic light transmission with a side port for irrigation. Results: We were able to obtain high-definition images of canaliculi, lacrimal sac, sac duct junction, proximal, mid and distal segments of nasolacrimal duct in all the children with CNLDO. In 17 primary cases 16 had distal membranous obstruction and I case had proximal canalicular obstruction. In nine children with history of failed probing, five had membranous obstruction, two had dacryoliths, two had NLD malformation at different levels. An overall success rate of 88.4% was achieved. Conclusion: Sialoendoscope can be used as high-definition dacryoendoscope for diagnostic and therapeutic use in CNLDO. Useful information can be obtained on dacryoendoscopy in complex CNLDO cases.

Introduction: Lacrimal drainage system disorders are among the most common ocular disorders faced by physicians. The prevalence of congenital nasolacrimal duct obstruction (CNLDO) is different in various studies, and the role of such factors as maternal and neonatal demographic characteristics have not been completely investigated in CNLDO. The present study aimed to assess the prevalence of CNLDO and its related factors in newborns in Sabzevar. Methods: This cross-sectional study was conducted on 541 newborns in Shahidan Mobini hospital, Sabzevar, Iran from January to February 2015 after obtaining informed consent from their parents. Data were collected by interviewing mothers, filling out checklists, and physical examination of the newborns. Data analysis was carried out in Stata software using a logistic regression test at a 95% confidence interval. Results: The prevalence of CNLDO was 22.6%. Purulent ocular discharge was the most common symptom (16.82%). There was a significant relationship between the neonate’s head circumference and the incidence of CNLDO (P= 0.01); nonetheless, CNLDO in the newborns showed no significant association with weight, height, and Apgar score (P>0.05). Conclusion: Considering the significant prevalence of CNLDO in preterm and term neonates, as well as its variable prevalence rates reported in different studies and the absence of overlapping of various risk factors of such disorder, it is recommended to carry out more thorough studies from birth to 1 year of age.

• Objective: Several pressure ulcer (PU) risk factors including paralysis and age greater than 70 have been identified, while others such as nutrition are debated. The object of this study is to identify perioperative risk factors that may predict improved outcomes and reduced complications in primary and recurrent PU reconstructions. • Method: A retrospective chart review of patients treated surgically for PUs from 2004 to 2013 at the University of Toledo Medical Center, Toledo, Ohio, US, was completed. Data collected included ulcer and medical history, as well as risk factors, complications and postoperative outcome. Data were statistically analysed for perioperative variances between primary and recurrent ulcers and closure status. • Results: A total of 49 patients with 102 reconstructions were reviewed. Spinal cord injured patients accounted for 90% receiving flap coverage of ulcers. Numerous differences between primary and recurrent ulcers were identified, including ulcer location, patient nutritional status, wound infection, postoperative course and recurrence. Multivariate analysis revealed a flap reconstruction prediction model using creatinine, haematocrit, haemoglobin, and prealbumin that is able to successfully predict closure outcome in 83.6% of cases. • Conclusion: Many factors play a role in the development, course and treatment of PUs. It is vital to understand the role of patient risk factors in the development of PUs, to direct subsequent management and reconstruction, and to prevent future recurrences.
