ABSTRACT

@#AIM: To investigate the prognostic value of DIP endoscopic scoring system for simultaneous operation of chronic dacryocystitis complicated with sinusitis.METHODS: From January 2018 to February 2021, 96 patients(96 eyes)with chronic dacryocystitis complicated with sinusitis who underwent nasal endoscopic sinus surgery and dacryocystorhinostomy were enrolled in a prospective single-blind study. Patients were examined by nasal endoscopy and recorded video to get DIP endoscopic score before operation. The patients were followed-up for 6mo, and the curative effect was based on the results of the last follow-up. The receiver operating characteristic curve(ROC curve)was drawn according to DIP endoscopic scoring system and postoperative curative effect, and the value of DIP endoscopic scoring system in predicting the prognosis of nasal endoscopic sinus surgery combined with dacryocystorhinostomy was evaluated. According to the best cutoff value obtained by ROC curve analysis, patients were analyzed in subgroups, and the age and sex constituent ratio of two groups were compared. RESULTS: Among the 96 eyes with chronic dacryocystitis complicated with sinusitis, 86 eyes(90%)were cured, 4 eyes(4%)were improved, and 6 eyes(6%)were invalid. ROC curve analysis showed that the area under the ROC curve(AUC)of DIP endoscopic score for predicting the curative effect of nasal endoscopic sinus surgery combined with dacryocystorhinostomy was 0.905. When Yoden index reached its peak, the DIP endoscopy score was 16.5 as the best cutoff value. At the same time, the sensitivity was 80.0% and the specificity was 86.0%. In the subgroup analysis, there was no significant difference in age and sex constituent ratio between the two groups(<i>P</i>>0.05); The surgical efficiency of patients with DIP endoscopic score <16.5 was better than the patients with DIP endoscopic score ≥16.5(<i>P</i><0.05).CONCLUSION: DIP endoscopic scoring system has a good predictive value for the prognosis of endoscopic of transnasal endoscopic sinus opening combined with dacryocystorhinostomy.
