          Abstract

          RESUMEN Nuestro objetivo es describir como realizamos la dacriocistorrinostomía (DCR) transcanalicular con láser diodo modificada conjuntamente los servicios de ORL y Oftalmología en el Hospital Universitario Río Hortega de Valladolid como tratamiento quirúrgico de la obstrucción primaria adquirida infrasacal del ducto nasolagrimal. Esta patología es bastante frecuente en pacientes de edad media y avanzada que origina epífora y blefaritis, así como dacriocistitis crónica o recurrente. En el tratamiento de esta entidad se sigue considerando, aunque cada vez menos, la dacriocistorrinostomía (DCR) externa como el gold standard con unas tasas de éxito que se sitúan alrededor del 85%. Sin embargo, en la actualidad, es considerada como una opción “invasiva”, que pone en riesgo estructuras como el mecanismo de bomba canalicular y puede generar una cicatriz poco cosmética. Estos riesgos potenciales se pueden evitar con técnicas menos invasivas (DCR endoscópica y la DCR transcanalicular con láser diodo modificada). La principal desventaja que puede presentar la técnica quirúrgica de dacriocistorrinostomía con láser diodo es la inversión económica por el alto coste del aparataje y su mantenimiento.

          SUMMARY Our aim is to describe how we perform laser transcanalicular modified dacryocystorhinostomy (DCR) the departments of ENT and Ophthalmology in HURH in Valladolid as surgical treatment of primary acquired nasolacrimal infrasacal duct obstruction (PANDO). PANDO is a common disorder in middle aged an older patient leading to chronic epiphora and blepharitis as well as recurring or chronic dacryocystitis. In the treatment of PANDO, external dacryocystorhinostomy (DCR) is still considered to be “the gold standard” with success rates above 85%. However, in recent years external DCR is considered an invasive procedure that puts at risk the medial structures of the eyelid including the physiological canalicular pump mechanism and leave pa-tient with an uncosmetic scar. These risks are potentially avoidable by performing less invasive techniques or choosing an endonasal approach (endoscopic or laser modified). One disad-vantage of laser modified surgery is the economic inversion because of the high cost of the equipment and maintenance.

          Nonlaser endoscopic endonasal dacryocystorhinostomy with adjunctive mitomycin C in nasolacrimal duct obstruction in adults.

          To determine the outcome and safety of nonlaser endonasal dacryocystorhinostomy (NLEN-DCR) with the use of adjunctive mitomycin C (MMC) in congenital, traumatic, and primary acquired nasolacrimal duct obstruction in adults. Retrospective, nonrandomized, noncomparative, case series. One hundred ninety-three consecutive adult patients underwent NLEN-DCR with the use of adjunctive MMC. Thirty-one patients had a simultaneous bilateral procedure performed. All patients underwent a standardized procedure, with an endonasal approach to the lacrimal sac, surgical removal of nasal mucosa, lacrimal bone, and a fragment of the frontal process of the maxilla. The medial wall of the lacrimal sac was removed completely, and a neurosurgical cottonoid soaked in MMC at 0.5 mg/ml was placed at the osteotomy site for 10 minutes. All patients underwent bicanalicular silicone intubation. Resolution of epiphora, absence of discharge, and patency of the ostium confirmed by irrigation at 6 months. The NLEN-DCR procedure with adjunctive MMC was successful in 212 (95%) cases. The mean follow-up was 18.2 months. Intubation of more than 3 months was associated with a higher rate of obstruction (P<0.00018, Fisher exact test), with 9 eyes of 8 patients losing patency. Age, diagnosis, side operated, or infection at the time of surgery had no influence on the final outcome. No significant complications were encountered. Results suggest that NLEN-DCR with MMC is a safe and successful procedure for the treatment of congenital, traumatic, and primary acquired nasolacrimal duct obstruction in adults. It has the advantage of leaving no scar and of preserving the medial canthal structures. It can be performed successfully as a simultaneous bilateral procedure.

            Five‐ and 10‐Year Outcomes for Primary Endoscopic Dacryocystorhinostomy: Failure Rate and Risk Factors

            Endoscopic dacryocystorhinostomy (eDCR) is the preferred approach for nasolacrimal duct obstruction, yet quality data on long-term outcomes is lacking.
