Analysis of the influence of postoperative personal care on the surgical outcomes of endoscopic dacryocystorhinostomy

Purpose: To investigate the impact of early postoperative personal care of endoscopic dacryocystorhinostomy (En-DCR) on surgical outcomes. Methods: This prospective study evaluated the early prognosis (1 month) and personal care of 90 patients with 94 eyes who underwent endoscopic dacryocystorhinostomy (En-DCR) for Chronic dacryocystitis（CD）. Surgical outcomes were divided into ostium grade and operative effect. Operative effect was judged by subjective symptom improvement, in addition to ostium assessment based on the results of nasal endoscopic review, and the relationship between operative effect and ostium grade was explored. In addition, we analyzed the key factors affecting operative effect and ostium grade during postoperative personal care. Results: The results of correlation analysis between operative effect and objective indicators showed that the outcomes of lacrimal duct irrigation（r=0.444，P＜0.001）, DDT（r=0.217，P=0.036）, and ostium grade（r=0.350，P＜0.001） were positively correlated with the operative effect of patients. The analysis of influencing factors during postoperative nursing showed that patients with nasal saline rinsing at least once a day after operation, nasal spray (Xylometazoline Hydrochloride and Budesonide) at least once a day after operation and without postoperative respiratory tract infection had better ostium grades and operative effect (P<0.05). Conclusions: The early surgical outcome of endoscopic dacryocystorhinostomy (En-DCR) is closely related to the condition of the ostium. During postoperative personal care, patients who maintain nasal saline rinsing and nasal spray (Xylometazoline Hydrochloride and Budesonide) at least once a day and reasonably prevent respiratory tract infection tend to have better recovery of early postoperative ostium and better operative effect. Medical staff should strengthen the home nursing guidance for patients after En-DCR day surgery.
