ABSTRACT
@#AIM: To investigate the proportional distribution of the size of lacrimal sac in recurrent dacryocystitis after the removal of artificial nasolacrimal duct and the clinical effect of dacryocystorhinostomy under nasal endoscope on patients with recurrent dacryocystitis.METHODS: Totally 73 patients(73 eyes)with recurrent dacryocystitis after removal of artificial nasolacrimal duct in our hospital from January 2018 to November 2019 were retrospectively studied. All patients underwent dacryocystography after hospitalization, and then performed dacryocystorhinostomy combined with intubation of double- artificial nasolacrimal duct under nasal endoscope and general anesthesia. The size of lacrimal sac was measured, and the area and effective rate of fistula were analyzed respectively at 2wk, 1, 3 and 6mo after operation. RESULTS: There were 13 eyes with large dacryocyst(Transverse diameter > 5mm, 18%), 26 eyes with middle dacryocyst(Transverse diameter between 2-5mm, 36%), and 34 eyes with small dacryocyst(Transverse diameter <2mm, 47%); There was significant difference in the stoma area of dacryocystostomy at 2wk, 1, 3, 6mo respectively(<i>P</i><0.05); Compared with 2wk, 1, 3mo after operation, the stoma area at 6mo after operation significantly decreased by 14.08±0.68, 10.49±0.75, 0.31±0.23mm2(all <i>P</i><0.05); The curative rates were 100%, 93%, 88% and 85% at 2wk, 1, 3, 6mo after operation, respectively. CONCLUSION: After the removal of the artificial nasolacrimal duct, the majority of the patients with recurrent dacryocystitis typically featured medium and small lacrimal sac. The curative effect of this type of recurrent dacryocystitis by dacryocystorhinostomy and intubation under nasal endoscope was proved to be effective, which could serve as a proper and better choice in clinic practice.
ABSTRACT
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)
