Abstract: An 84-year-old female patient with neoplasm in her right tear duct had been present for half a year, and she came to the clinic after a previous visit to other hospitals and a recurrence of the disease 10 days after surgical treatment, and then she repeatedly underwent lachrymal flushing with no improvement. After a series of examinations, the patient was diagnosed with lachrymatorrhoea with tear duct neoplasm. The patient was given the right tear duct neoplasm excision, tear duct drainage tube implantation, etc. After standardized treatment, the patient’s right eye increased secretion, tearing, redness symptoms disappeared. Basic information】Female, 84 years old 【Disease type】 Right tear duct inflammation 【Hospitalization】 The First Affiliated Hospital of China Medical University 【Time of consultation】January 2015 【Treatment plan】Surgical treatment (right teardrop neoplasm excision, lacrimal canalicotomy and scraping, lacrimal duct drain implantation) + medication (levofloxacin drops) 【Treatment cycle】Hospitalization for 3 days, and review half a month later 【Treatment effect】 Increased secretion in the right eye, overflow of tears, and redness of the eye disappeared after standard treatment. Treatment effect] Increased secretion, tear overflow and redness of the right eye disappeared I. Initial Consultation The patient was an elderly woman, 84 years old, who consulted the doctor because of the growth of new organisms in the right tear duct for half a year, and she had been treated in a foreign hospital, and was diagnosed to have the swelling in the right tear duct surgically excised without pathological examination. Examination revealed that the visual acuity of both eyes was 0.15, and the corrected visual acuity was 0.3. A round cord-like appendage-like neoplasm was found in the right tear duct, which was about 10mm long and 2mm in diameter, and was L-shaped, red in color, soft in texture, with purulent secretion visible on the surface, and cloudy lens in both eyes, with no anterior or posterior segment abnormality. Lacrimal flushing was performed, and the flushing needle encountered slight resistance, after changing the direction, the lacrimal flushing was smooth, and no secretion or reflux fluid was seen. After the patient was admitted to the hospital, it was clearly diagnosed as right tear duct inflammation, accompanied by neoplasm of tear duct. Under local anesthesia, the patient underwent resection of the new organism in the right tear duct, lacrimal canalicotomy and scraping, and implantation of a lacrimal drainage tube. During the operation, the root of the neoplasm was located in the lacrimal canal, which was soft and brittle, and a probe was inserted into the lacrimal bone by expanding the lacrimal punctum, and the lacrimal canal was incised horizontally from the lacrimal punctum, and the mucus and tofu dregs-like stones were scratched out, and the wall of the lacrimal canal was coated with tincture of iodine, and the lacrimal drain was implanted, and the lacrimal incision was closed, and the resected neoplasm was sent to the postoperative pathology, which showed that the right lacrimal punctum had acute suppurative inflammatory changes. Postoperatively, levofloxacin eye drops were given for 2 weeks. The patient was hospitalized for 3 days without any abnormality, and was discharged from the hospital, and was instructed to be rechecked after half a month. After the surgery, the symptoms of increased secretion, tearing and localized redness and swelling of the right eye disappeared completely. Half a month after surgery, the tear duct was flushed smoothly. Three months after surgery, after removing the tear duct drainage tube, the tear duct flushing was smooth, and no new organisms grew, no tearing, local redness and swelling, etc. The patient reported that she had no other uncomfortable symptoms, and her recovery was good. The patient reported no other discomfort and recovered well. We are glad that the patient’s ocular discomfort disappeared after surgery. However, after the surgery, the patient should avoid staying in the dusty environment, keep the local area clean and clean, and eat a light diet. In addition, during the period of patients with tubes, appropriate local hot compresses and massages can be applied, which is conducive to the subsidence of local inflammation and the recovery of tear duct function. As the surgery retained the integrity of the tear point and tear duct, from the perspective of long-term effect, it well solved the symptoms of localized tear duct structure destruction and continued tear overflow after the surgery. V. Personal insights Combined with the analysis of this patient, consider that the diameter of the nasolacrimal duct in women is narrower than that in men, and it is easy to be obstructed. Lacrimal duct stones found during surgery are mostly formed due to calcification of local necrotic tissues and other calcifications, and when the stones are obstructed in the lacrimal punctum, the patient may have an obvious foreign body sensation. The key to surgical treatment is to completely remove the lacrimal duct stones, prevent adhesion and occlusion of the lacrimal duct, and protect the integrity of the lacrimal punctum.
