The Application of Photosensitive Hydrogel in Intranasal Endoscopic Dacryocystorhinostomy
The Application of Photosensitive Hydrogel in Intranasal Endoscopic Dacryocystorhinostomy for the Anastomosis of Lacrimal Cyst Flap and Nasal Mucoperiosteal Flap
Eye & ENT Hospital of Fudan University

INTERVENTIONAL
Conditions
Summary
To study the effect of Photosensitive hydrogel used for suture free anastomosis of lacrimal cyst and nasal mucoperiosteal flap in endoscopic nasal dacryocystostomy, and evaluate its adhesion to lacrimal cyst and nasal mucoperiosteal flap, promoting wound healing, forming a good anastomosis, preventing postoperative anastomosis and shortening operation time. Twenty patients with chronic dacryocystitis were randomly divided into photosensitive hydrogel group and suture group.Symptoms and nasal endoscopy were followed up 2, 6, and 12 weeks after surgery for both groups. And also adverse events were recorded at each follow-up.
Eligibility
Inclusion Criteria4
- Voluntarily participate in this clinical study and sign the informed consent;
- Gender is not limited, age 18-75 years old;
- The patient had symptoms and signs of chronic dacryocystitis, and the results of lacrimal passage irrigation suggested that the lower rush and return or upper rush and lower return, accompanied by mucous or purulent discharge reflux;
- Lacrimal duct angiography suggests nasolacrimal duct obstruction without lacrimal canaliculi and/or duct obstruction.
Exclusion Criteria11

- Previous history of dacryocystonasal anastomosis;
- Abnormal coagulation function;
- Tumors of lacrimal passage, especially in patients with papilloma or malignant tumors;
- in the acute dacryocystitis attack stage;
- obvious scar constitution;
- Complicated with serious nasal diseases, such as severe allergic rhinitis, chronic rhinosinusitis and nasal polyps, acute suppurative rhinosinusitis, severe atrophic rhinitis, and severe deviation of nasal septum;
- Have serious heart, liver, kidney, lung and other basic diseases, can not tolerate general anesthesia;
- Distance from the hospital, postoperative review is not convenient;
- Participated in other clinical trials within the last 3 months;
- Any medical history that the investigator determines may interfere with the test results or increase the patient's risk.

Interventions
In the photosensitive hydrogel group, the anastomosis of the lacrimal cyst mucosal flap and the nasal mucoperiosteal flap was achieved by photosensitive hydrogel.
In the suture fixation group, the anastomosis of the lacrimal cyst mucosal flap and the nasal mucoperiosteal flap was achieved by two stitches using 6-0 absorbable wire.
