Valor del ultrasonido en el diagnóstico de los tumores del saco lagrimal / Value of the ultrasound in the diagnosis of lacrimal sac tumor

RESUMEN Los tumores del saco lagrimal son extremadamente raros, y el benigno primario más común es el papiloma escamoso. Clínicamente se manifiestan como una zona de tumefacción en la región cantal medial, asociado a epifora y dacriocistitis crónica-recurrente. Dentro de las pruebas de imagen recomendadas están: dacriocistografía, tomografía computarizada, resonancia magnética y dacrioescintifotografía. Sin embargo, muy pocos sugieren el uso del ultrasonido. Se presenta el caso de un papiloma mixto del saco lagrimal diagnosticado por ultrasonido. Se trata de una paciente femenina de 39 años, quien fue remitida por cuadros repetidos de dacriocistitis derecha en los últimos 3 años. En consulta se constató celulitis preseptal ipsolateral, por lo que se indicó antibiótico-terapia, y se logró la remisión de los signos inflamatorios agudos, pero persistió el aumento del volumen cantal medial derecho. La vía lagrimal se exploró y se comprobó que estaba obstruida. Se realizó ultrasonido, donde el saco lagrimal derecho apareció ocupado por una masa ecogénica, que se extendía al conducto lacrimonasal y mostraba ligera vascularidad. Seguidamente se hizo tomografía computarizada, y se confirmaron los hallazgos ecográficos, pero sin lograr delimitar la lesión intrasaco descrita, aún tras la administración de contraste yodado endovenoso. Se sugirió dacriocistitis crónica derecha, secundaria al tumor intrasaco de aspecto benigno, probable papiloma, por lo que se efectuó cirugía y examen histopatológico que ratificaron dicho diagnóstico. En conclusión, el ultrasonido del saco lagrimal es un método complementario de gran valor, que en algunos casos hará el diagnóstico, y en otros brindará información que optimizará la decisión de quienes serían tributarios a estudios más complejos(AU)

ABSTRACT Lacrimal sac tumors are extremely rare, and the most common benign primary is squamous papilloma. Clinically, they manifest as a zone of swelling in the medial canthal region, associated with epiphora and chronic-recurrent dacryocystitis. Among the recommended imaging tests are dacryostography, computed tomography, magnetic resonance imaging, and dacryoscintifotography. However, very few suggest the use of ultrasound. The case of a mixed papilloma of the lacrimal sac diagnosed by ultrasound is presented. This is a 39-year-old female patient, who was referred for repeated cases of right dacryocystitis in the last three years. In consultation, ipsolateral preseptal cellulitis was found, for which antibiotic therapy was indicated, and the remission of acute inflammatory signs was achieved, but the increase in right medial canthal volume persisted. The lacrimal duct was explored and found to be obstructed. Ultrasound was performed, where the right lacrimal sac appeared occupied by an echogenic mass, which extended to the lacrimal duct and showed slight vascularity. Subsequently, computed tomography was performed, and the ultrasound findings were confirmed, but without defining the described intrasaccal lesion, even after administration of intravenous iodinated contrast. It was suggested chronic right dacryocystitis, secondary to apparently benign intrasaccal tumor, probable papilloma, so surgery and histopathological examination were performed, which that ratified the diagnosis. In conclusion, ultrasound of the lacrimal sac is a complementary method of great value, which in some cases will make the diagnosis, while in others it will provide information that will optimize the decision of those who would be candidate to more complex studies(AU)

Bilateral Simultaneous Endoscopic Dacryocystorhinostomy: Outcome and Impact on the Quality of Life of the Patients.

Introduction Bilateral simultaneous endoscopic dacryocystorhinostomy (endo-DCR) has received little attention in the literature, thus many surgeons continue to address bilateral nasolacrimal duct obstruction at two stages, rather than in the same setting. Objective To evaluate the feasibility and the outcome of simultaneous bilateral Endo-DCR and its impact on the quality of life of the patients. Methods We have conducted a retrospective analysis of patients who underwent bilateral simultaneous endo-DCR between March 2013 and February 2017 at our tertiary care institution. The reviewed data included clinical presentation; operative details; success rate; pre and postoperative evaluation of the symptoms of the patients, using the Nasolacrimal Duct Obstruction Symptom Score Questionnaire; satisfaction of the patients, and improvement in the quality of life, assessed by the Glasgow Benefit Inventory (GBI) questionnaire. Results Out of 128 cases in which endo-DCRs were performed, 13 were bilateral (26 sides). Postoperative success was documented in 24 of the 26 sides (92.3%), with a mean follow-up duration of 16.2 months. The two failed sides were reported in the same case. The preoperative symptom score ranged between 12 and 80 (mean ± standard deviation [SD]: 38.23 ± 15.7). The postoperative symptom score was significantly lower (mean ± SD: 5.4 ± 12.9). The success rates in unilateral and bilateral cases were comparable, with no statistically significant difference. A notable improvement in the quality of life of the patients was also reported, with a mean GBI score of 81.38 ± 12.37. Conclusion Our results support that a simultaneous bilateral endo-DCR is a safe procedure that offers a high success rate, spares the patient from the stress of a second surgery, provides the patient with a bilateral resolution of the symptoms, and confers an immediate improvement in the quality of life of the patients.

Ultrasonic 3D reconstruction and measurement of lacrimal sac in normal adult Chinese population / Reconstrucción 3D con ultrasonido y mediciones del saco lagrimal en una población china de adultos normales

To apply the ultrasonic 3D reconstruction method to measure the anatomic image data of lacrimal sac in the normal adult Chinese population, providing imaging anatomical basis for the clinical diagnosis and treatment of lacrimal duct diseases. 80 volunteers without lacrimal duct diseases were enrolled. The GE Voluson E8 ultrasonic diagnostic apparatus was used, with gynecological intracavitary probe (frequency: 5 ~ 12MHz) for the examination and measurement. Each datum was repeated three times for the average value. Among the 80 eyes, the lacrimal sacs of 74 eyes exhibited the clear imaging, with the imaging rate as 92.5 %. the vertical diameter of lacrimal sac cavity (LSC): 13.3±2.2 mm; anteroposterior diameter: 6.0±1.1 mm; trans diameter: 4.9±0.9 mm; the vertical distance from the sac cavity top to the skin surface: 6.3±0.12 mm, the vertical distance from the sac cavity bottom to the skin surface: 6.5±0.11 mm; the distance from the angular artery to the medial canthus: 7.8±0.05 mm; the vertical distance from the angular artery to the skin surface: 7.7±0.08 mm. The lacrimal sac and angular artery in the adults could be shown clearly in ultrasonic 3D reconstruction, the accumulated anatomical parameters could provide the instructive meanings towards the clinical diagnosis and treatment of lacrimal diseases.

El objetivo de este estudio consistió en aplicar el método de reconstrucción 3D de ultrasonidos para medir los datos de las imágenes anatómicas del saco lagrimal en una población china adulta normal, proporcionando imágenes con base anatómica para el diagnóstico clínico y el tratamiento de las enfermedades de los conductos lagrimales. La muestra consistió en 80 voluntarios sin enfermedades de los conductos lagrimales. Se utilizó el aparato de ultrasonido GE Voluson E8, con una sonda intracavitaria ginecológica (frecuencia: 5 ~ 12 MHz) para realizar el examen y la medición. Cada dato se repitió tres veces para obtener el valor medio. De los 80 ojos, los sacos lagrimales de 74 ojos mostraron una imagen clara, siendo la tasa de formación de imágenes del 92,5 %. Se realizaron mediciones: diámetro vertical de la cavidad del saco lagrimal (LSC): 13,3 ± 2,2 mm; diámetro anteroposterior: 6,0 ± 1,1 mm; diámetro transversal: 4,9 ± 0,9 mm; distancia vertical desde la porción superior de la cavidad del saco lagrimal hasta la superficie de la piel: 6,3 ± 0,12 mm, distancia vertical desde el fondo de la cavidad del saco lagrimal hasta la superficie de la piel: 6,5 ± 0,11 mm; distancia desde la arteria angular al canto medial: 7,8 ± 0,05 mm; distancia vertical desde la arteria angular a la superficie de la piel: 7,7 ± 0,08 mm. El saco lagrimal y la arteria angular en los adultos se podría demostrar claramente en la reconstrucción 3D con ultrasonido. Los parámetros anatómicos acumulados podrían ser de significativo valor para un certero diagnóstico clínico y tratamiento de enfermedades de los sacos lagrimales.
