本研究では、特別に設計されたユニポータル内視鏡システムを用いたユニポータル内視鏡下胃大脳筋後退術の有効性と安全性を検討した。53人の患者が60回の内視鏡的腓腹筋後退術を受けた。足首背屈の平均範囲は術前の-2.9°±1.9°から術後の12.8°±1.7°に変化し、合計15.7°±1.8°の足首背屈が増加した(p < 0.001)。皮膚切開から閉鎖までの平均時間は4分19±33.6秒であった。全体では、4例(6.67%)の症例(処置)が合併症と関連しており、そのうち1例(1.67%)は理学療法後に消失した上腕三頭筋脱力症であった。神経合併症を発症した症例は3例(5%)で、術後5週目と8週目に自然に消失した一過性神経炎が2例(3.33%)、術後4ヶ月まで足の側面に沿った硬膜神経の分布に持続的な皮下麻酔を経験した1例(1.67%)がそれぞれ認められた。創傷の脱離や治癒遅延、疼痛性瘢痕形成、手術部位の感染、血腫、深部静脈血栓症は認められなかった。ユニポータルシステムを用いた内視鏡的腓腹筋後退術は安全で効果的であると考えられる。
This study examined the effectiveness and safety of a uniportal endoscopic gastrocnemius recession with a specifically designed uniportal endoscopic system. Fifty-three patients underwent 60 endoscopic gastrocnemius recessions. Their mean range of ankle dorsiflexion changed from a preoperative value of -2.9° ± 1.9° to a postoperative value of 12.8° ± 1.7°, for a total increase of 15.7° ± 1.8° of ankle dorsiflexion (p < .001). The average time from skin incision to closure was 4 minutes and 19 ± 33.6 seconds. Overall, 4 (6.67%) cases (procedures) were associated with a complication, including 1 (1.67%) case of triceps surae weakness that resolved after physical therapy. Three (5%) cases developed nerve complications, with 2 (3.33%) cases of transient neuritis that spontaneously resolved at 5 and 8 weeks postoperatively, respectively, and 1 (1.67%) that experienced persistent cutaneous anesthesia in the distribution of the sural nerve along the lateral aspect of the foot up to 4 months postoperatively. There were no cases of wound dehiscence or delayed healing, painful scar formation, infection at the surgical site, hematoma, or deep venous thrombosis. Endoscopic gastrocnemius recession with a uniportal system appears to be safe and effective.
