Objective To investigate the therapeutic effect of minimally invasive small incision surgery under local anesthesia for pediatric stenosing tenovaginitis of thumb. Methods A retrospective analysis was conducted on the medical records of children with stenosing tenovaginitis of thumb who received small incision tendinolysis under local anesthesia at West China Hospital of Sichuan University between January 2013 and August 2022, to evaluate and analyze the safety and effectiveness of the surgery. Results A total of 949 pediatric patients were included, with an average age of (3.23±1.92) years. The average duration of surgery was (7.0±2.5) minutes, and the average follow-up time was (3.91±5.32) months. All patients did not need to fast for solids and liquids before surgery, and were immediately discharged from the hospital after outpatient surgery. The family members of the patients were highly satisfied with the treatment process and postoperative recovery. All patients had no nerve or vascular damage, and the wound margin skin showed linear healing with mild scars that fused with palm prints. There were 825 cases (86.93%) of children with thumb function fully restored to normal, 113 cases (11.91%) with limited maximum dorsiflexion function of the thumb, and 11 cases (1.16%) with recurrent stiffness of the thumb metacarpophalangeal joint. Conclusion Small incision tendinolysis under local anesthesia is a safe and effective treatment for pediatric stenosing tenovaginitis of thumb, with high satisfaction among the patients’ family members.
目的 評價依托芬那酯凝膠治療腱鞘炎在超聲引導下微創術后腫痛的有效性和安全性。 方法 采用隨機、對照的設計，將2011年5月－2012年7月，在四川省人民醫院門診接受腱鞘炎超聲引導微創術后的患者157例，分為兩組，治療組（n=81）采用依托芬那酯凝膠外用，對照組（n=76）不使用外用藥物。 結果 兩組治療后24 h及3 d的疼痛評分、壓痛及關節功能緩解率與治療前自身比較及組間比較，差別均有統計學意義（P＜0.05），7 d時治療組臨床總有效率為90.12%，對照組為89.47%，組間比較無統計學意義（P＞0.05），治療組在使用應急藥物上明顯優于對照組。兩組安全性評價比較差異無統計學意義（P＞0.05）。 結論 依托芬那酯凝膠能快速、有效、安全地緩解腱鞘炎超聲引導微創術后局部腫脹疼痛的癥狀。
