要約 目的:一般に急性涙囊炎は抗菌薬などによる消炎を行ったのちに手術加療を行うことが多いが,手術時期が遅れると涙囊皮膚瘻などの有害事象を生じる場合があり,近年では発症早期に外科的手術が行われることも増えてきている。急性涙囊炎発症後早期に兵庫県立尼崎総合医療センター(以下,当院)で鼻内視鏡下涙囊鼻腔吻合術(EnDCR)を施行した患者の手術成績を報告する。
対象と方法:2022年1月〜2025年3月に当院で急性涙囊炎の診断によりEnDCRを施行した患者のうち,発症後14日以内の症例を急性期群,15日以降の症例を対照群として,術後成績を比較検討した。
結果:急性期群および対照群において,症例数は9例および16例,平均年齢は78.2歳および74.8歳,発症から手術までの日数は3〜12日(平均7日)および15〜63日(平均31日)であった。術翌日に腋窩温37℃台の発熱を認めた症例は急性期群で5例(55.6%),対照群で11例(68.8%)であったが,いずれも経過観察で解熱を認めた。そのほかに重篤な有害事象や合併症は認めなかった。涙液メニスカス高は急性期群で術前0.425±0.056mm,術後0.128±0.058mm(p=0.0032),対照群で術前0.404±0.226mm,術後0.180±0.090mm(p=0.0013)と,両群で有意な改善を認めた。また,通水検査でも通過が認められ,吻合孔に異常を認めなかった。
結論:急性涙囊炎に対する早期のEnDCRは,安全で有効な治療選択肢の1つである。
Abstract Purpose:Acute dacryocystitis is often treated with anti-inflammatory agents, such as antibiotics, followed by surgical intervention. However, delayed surgery may lead to adverse events, such as dacryocystorhinostomy fistula. Recently, early surgical intervention has become increasingly common. Here, we report the surgical outcomes of patients who underwent endoscopic dacryocystorhinostomy(EnDCR) early after developing acute dacryocystitis at our institution.
Materials and Methods:Postoperative outcomes of patients diagnosed with acute dacryocystitis and those who underwent EnDCR at the Amagasaki General Medical Center between January 2022 and March 2025 were compared. Patients treated within 14 days of symptom onset were classified into the acute-phase group, whereas those treated after≧15 days were classified into the control group.
Results:The acute-phase and control groups comprised nine(mean age;78.2 years) and 16(mean age;74.8 years) cases, respectively. The number of days from symptom onset to surgery ranged from 3-12 days(mean;7 days) and 15-63 days(mean;31 days), respectively. Fever(axillary temperature in the 37℃ range) was observed on postoperative day 1 in five(55.6%) and 11(68.8%) cases in the acute-phase and control groups, respectively;however, fever resolved in all cases during follow-up. No serious adverse events or complications were observed. The tear meniscus height was 0.425±0.056 mm preoperatively and 0.128±0.058 mm postoperatively(p=0.0032) in the acute-phase group, and 0.404±0.226 mm preoperatively and 0.180±0.090 mm postoperatively(p=0.0013) in the control group. Significant improvements were observed in both groups. Furthermore, water flow tests demonstrated patency, and no abnormalities were observed at the anastomotic site.
Conclusion:Early EnDCR for acute dacryocystitis should be considered a safe and effective treatment option.
