Según el criterio del cirujano, la mejoría objetiva se obtuvo en el 88,0 por ciento de los casos. La dacriocistorrinostomía externa fue más frecuente en mujeres blancas encontradas entre su sexta y séptima década de vida. El lado izquierdo fue el más afectado con predominio de la etiología involutiva. Las complicaciones fueron escasas; dentro de ellas predominó el sangramiento transoperatorio. Conclusiones: la mayoría de los pacientes sintieron mejoría después de la cirugía; el criterio del cirujano estuvo a favor de los resultados positivos en la cirugía dacriocistorrinostomía externa(AU)

Objective: to describe the results of external dacryocystorhinostomy surgery in one year. Methods: a prospective, longitudinal descriptive and observational study was conducted in 28 patients from 25 patients. The study variables were gender, race, age, affected side, etiology, complications and surgery outcomes. Results: there were 7 male and 18 female patients, 16 Caucasians and 9 non-Caucasians with statistically significant difference (p= 0,043). The mean age was 69 ± 11 years. The obstruction involved the left side in 13 patients (52 percent) and involution was the main etiology in 68 percent with statistical significance (p= 0,0003). Perioperative bleeding was the main complication (24 percent). In the group, 92 percent said the symptoms had reduced after surgery, and according to the surgeon, objective improvement was attained in 88 percent of cases. Conclusion: external dacryocystorhinostomy was more frequent in Caucasian women aged 60 to 70 years. The left side was the most affected, with prevailing involution etiology. There were minimum complications, being perioperative bleeding predominant. Most of the patients felt better after surgery and the surgeon´s criteria were in favor of the positive results of this surgery(AU)

Dacriocistorrinostomía endoscópica: experiencia de 4 años del Hospital Clínico de la Universidad de Chile / Endoscopic dacryocystorhinostomy: four years experience at the Clinical Hospital of the University of Chile

Introducción: La dacriocistorrinostomía abierta es el gold estándar para el tratamiento de la obstrucción nasolacrimal, patología manifestada como epífora crónica, dacriocistitis y conjuntivitis recurrente. Desde el desarrollo del abordaje endonasal, se ha considerado como una alternativa terapéutica eficaz con notorias ventajas respecto a la técnica abierta y que además ofrece la posibilidad de corregir otras alteraciones de la nariz y cavidades paranasales en el mismo tiempo quirúrgico. Objetivo: Evaluar los resultados de la técnica quirúrgica endoscópica según la realidad del Hospital Clínico de la Universidad de Chile, durante los años 2010-2014. Determinar la etiología de la obstrucción en los pacientes intervenidos. Material y método: Se realizó un estudio de cohorte retrospectivo con revisión de fichas clínicas de pacientes con diagnóstico de obstrucción de la vía lacrimal sacular y postsacular sometidos a dacriocistorrinostomía endoscópica. Se incluyeron 27pacientes entre los cuales se realizaron 33 cirugías, ya que 22,2% de ellos (6/27) fueron sometidos a intervención bilateral. Resultados: El éxito quirúrgico objetivo y subjetivo se presentó en 75,8% (25/33) y 65,4% (17/26) respectivamente. El 7,4% (2/27) presentaron complicaciones intraoperatorias (falsa vía y extrusión de grasa orbitaria) y 18,5% (5/27) complicaciones posoperatorias (sinequias y fibrosis). Dentro de las causas destacan: idiopática 66,7% (18/27), postraumática 14,8% (4/27), secundaria a utilización de radioyodo 11,1% (3/27), granulomatosis de Wegener3,7% (1/27)y congénita 3,7% (1/27). La sonda instalada se mantuvo por un promedio de 3,5 meses, y el seguimiento se realizó por un periodo de 7,4 meses. Conclusión: La dacriocistorrinostomía endoscópica resulta ser una excelente herramienta quirúrgica para el manejo de pacientes con diagnóstico de obstrucción nasolacrimal, siendo un procedimiento exitoso, seguro, con baja tasa de complicaciones y una muy buena evolución posoperatoria, recomendado para todos aquellos casos con mala respuesta a las terapias médicas.

Introduction: Open dacryocystorhinostomy is the gold standard for the treatment of nasolacrimal obstruction, pathology manifested as chronic epiphora, recurrent dacryocystitis and conjunctivitis. Since the development of endonasal approach, it has been considered as an alternative therapy with notable advantages over the open technique and offers the possibility to correct other abnormalities of the nose and paranasal sinuses in the same surgical time. Aim: To evaluate the results of endoscopic surgical technique according to the reality of the Clinical Hospital of the University of Chile, during the years 2010-2014. Determine the etiology of the obstruction in patients undergoing surgery. Material and method: A retrospective cohort study was performed with review of clinic files of patients diagnosed with lacrimal duct obstruction submitted to an endoscopic dacryocystorhinostomy. 27 patients were included and 33 surgeries were performed, as 22.2% of them (6/27) underwent bilateral intervention. Results: Objective and subjective surgical success occurred in 75,8% (25/33) and 65,4% (17/26) respectively. 7,4% (2/27) had intraoperative complications (false passage and orbital fat extrusion) and 18,5% (5/27) postoperative complications (fibrosis and synechiae). Among the causes are: idiopathic 66,7% (18/27), postraumatic 14.8% (4/27), history of radioiodine use 11.1% (3/27), Wegener's granulomatosis 3.7% (1/27) and congenital 3.7% (1/27). Probe Installed was kept for an average of 3,5 months, and the follow-up was performed for 7,4 months. Conclusions: Endoscopic dacryocystorhinostomy is an excellent surgical tool for the management of patients with nasolacrimal obstruction. It's a successful procedure, with low rate of complications and good postoperative outcome, recommended for those cases with poor response to medical therapies.

Dacryocystorhinostomy at Ramathibodi Hospital.

Two hundred and seventy patients with idiopathic obstruction of the lacrimal passage between the sac and the nasolacrimal duct, who underwent external dacryocystorhinostomy at the Department of Ophthalmology, Ramathibodi Hospital were studied retrospectively. All the patients had the operations between 1983 and 1987; 240 were female (88.9%) and 30 were male (11.1%), with, a ratio of 8 female to 1 male. The ages ranged from 3 to 83 years, with the peak in the 46-55 age group (25.19%). The overall surgical success rate was 86.5 per cent, the definition for success being a relief of the obstruction as evident symptomatically and by the ability to irrigate the saline from the puncta to the nasal cavity at follow-ups of more than 21 days postoperatively. The patients were further subdivided into the "silastic" group and the "non-silastic" group: and the success rate were 75.5 and 95.7 per cent respectively. Significant complications of the dacryocystorhinostomy were recorded in 11 cases; 2 wound infections, 2 lacrimo-cutaneous fistulae, 5 severe operative hemorrhage and 2 ethmoidal sinus involvement.
