@#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.

Anatomic characteristics of the lacrimal sac in the nasal cavity of recurrent dacryocystitis and its application in endoscopic dacryocystorhinostomy combined with stent implantation / 解剖学报

Objective To observe the efficacy of endoscopic nasal dacryocystoma anastomosis combined with stent implantation in the treatment of chronic recurrent dacryocystitis. Methods Thirty patients (30 eyes) with chronic dacryocystitis who had relapsed after traditional endoscopic nasal dacryocystorhinostomy were hospitalized in the Department of Otolaryngology Head and Neck Surgery department of Gansu Provincial People's Hospital from January 2010 to January 2019. Nasal lacrimal anastomosis under endoscope, intraoperative combined stent implantation, 3 months after operation, the lacrimal duct stent was removed, the patient ' s tearing symptoms were observed, the lacrimal duct was flushed to determine the lacrimal duct obstruction, and the follow-up period was 12 months. Results Twelve months of follow-up to 12 months, 14 eyes of 30 patients had no complaints of tearing, tearing, and lacrimal tract flushing; The ostomy fistula was unobstructed under nasal endoscope and the fistula was not significantly reduced. There was no complaint of tears in the eyes, tears overflowed, and the lacrimal duct was flushed, but the fistula opening was reduced.; Four eyes showed granulation hyperplasia next to the fistula, which blocked the fistula again. The overall effective rate was 87%. Conclusion Endoscopic dacryocystorhinostomy combined with stent implantation is an effective method for the treatment of chronic recurrent dacryocystitis with good clinical result.

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)

Effect of revision dacryocystorhinostomy under nasal endoscopy on recrudescent dacryocystitis.

OBJECTIVE: Patients with recurrent dacryocystitis are difficult to treat. We aimed to observe the role of dacryocystography in locating the site of obstruction and the effect of revision surgery in these cases of recurrent dacryocystitis. METHOD: We prospectively collected patients with recurrent dacryocystitis at West China Hospital of Sichuan University. Dacryocystography was performed before surgery. After revision endoscopy dacryocystorhinostomy (DCR), patients were followed-up regularly. Clinical features were recorded before and after operation, including the visual analog scale (VAS) score. Using the software of SPSS 13.0, VAS scores were compared between preoperation and postoperation by a Student's t test and repeated measure ANOVA. RESULTS: Twenty patients were collected; eight cases had a history of a one-time occurrence of DCR, and 12 cases had a history of two or more occurrence of DCR. Dacryocystography could show the site with the most lacrimal obstruction. During the operation, we could resect most of the lacrimal sac medial bone wall and expose the sac successfully. Follow-up showed no relapse occurrences and only one case had a slightly tearful eye subjectively but had enough big orificium fistulae and favorable mucosal epithelialization that it was similar to other cases. The VAS scores at follow-up decreased significantly compared with preoperation (P<0.05). CONCLUSION: For patients with recurrent dacryocystitis, dacryocystography could clarify the cause and exact site of the obstruction and provide information for further treatment. Through revision endoscope DCR, patients can effectively achieve enough drainage of the lacrimal sac accompanied with a significant improvement in symptoms and no observable complications.

Outcomes of revision external dacryocystorhinostomy and nasal intubation by bicanalicular silicone tubing under endonasal endoscopic guidance.

AIM: To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocystorhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. METHODS: Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. RESULTS: Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3±3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 ± 9.3 months. After a mean follow-up of 14.9±7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). CONCLUSION: Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.

Successful endonasal dacryocystorhinostomy in a patient with Wegener's granulomatosis.

Wegener's granulomatosis (WG) is one form of idiopathic autoimmune vasculitis. The disease has a predilection for the upper and lower respiratory tracts (lungs, nose, sinus), and kidneys. WG may be systemic, severe, and potentially lethal, but it may also be limited to the otolaryngological area or to the eyes and the orbits. Obstruction of the lacrimal pathway is a possible complication of the disease that affects approximately 7% of patients with WG. It usually occurs as a direct extension of sinonasal disease and typically is a late manifestation. Management of such a condition is generally viewed as difficult. We report the case of a patient with a quiescent WG limited to the otolaryngological area. This patient presented a bilateral obstruction of the nasolacrimal ducts caused by bilateral extensive adhesions in the nasal cavity. Because she had several episodes of left-side acute dacryocystitis which necessitated several courses of broad-spectrum antibiotics, she successfully underwent an endonasal endoscopic dacryocystorhinostomy using a diode laser and powered instrumentation. The authors describe the clinical case, the surgical technique, and review the literature.
