Features of the Postoperative Period in Patients with Chronic Dacryocystitis and Type 2 Diabetes Mellitus after Endoscopic Endonasal Dacryocystorhinostomy Depending on the Degree of Compensation of Diabetes Mellitus

Abstract

The aim. To identify the features of the postoperative period in patients with chronic dacryocystitis and type 2 diabetes mellitus (DM2) after endoscopic endonasal dacryocystorhinostomy (DCR), depending on the degree of compensation of DM. Materials and methods. The study involved 30 DM2 patients with chronic dacryocystitis who underwent endoscopic endonasal DCR according to standard methods. The patients were divided into groups according to the degree of compensation of DM2: 6 patients with compensated, 7 patients with subcompensated and 17 patients with decompensated DM2. The results of the operation were evaluated after 2 months, 6 months and 2 years. In addition to standard methods, ophthalmic examination included nasolacrimal duct probing, lacrimal duct lavage, and endoscopic examination of the nasal cavity. Results and discussion. The efficiency of endoscopic endonasal DCR in decompensated DM2 after 2 months (58.8 ± 11.9 % of patients) on average was 1.4 times, and after 6 months (52.9 ± 12.1 % of patients) and 2 years (41.2 ± 11,9 % of patients) – it was 1.5 times less than that in subcompensated and compensated DM2 (p < 0.05). In patients with decompensated DM2, tearing was observed in 41.2 ± 11.9 % of patients after 2 months, in 47.1 ± 12.1 % of patients after 6 months and in 58.8 ± 11.9 % of patients after 2 years post-op, which was, on average, 2.7 times, 2.1 times and 1.5 times more often than that in subcompensated and compensated DM2, respectively (p < 0.05); there were no significant differences between the values (p > 0.05). Conclusions. Features of the postoperative period in patients with chronic dacryocystitis after endoscopic endonasal DCR depend on the degree of compensation of DM2. The efficiency of endoscopic endonasal DCR in decompensated DM2 after 2 months is on average 1.4 times, and after 6 months and 2 years it is 1.5 times less than that in subcompensated and compensated DM2.
