摘要: Abstract Purpose: The authors used ultrasonographic endoprobes during laparoscopy-assisted colon pull-through (LACPT) for the repair of high imperforate anus to confirm canal was surrounded symmetrically by pelvic floor muscles. Methods: Six patients with were treated LACPT (mean age at LACPT, 8.2 months). An endoscopic (12-MHz, 2.5-mm in diameter) and proctoscopic (7.5-MHz, 12-mm probe inserted into proposed route dissection intraoperatively measure thickness surrounding muscle tissue least 3 levels: external anal sphincter, levator ani sling, intervening complex. Results: average sphincter 2.3 ± 0.4 mm anteriorly, 2.4 on left, 0.5 posteriorly, 2.6 0.6 right. complex 2.2 2.1 left crus 1.8 0.3 mm, right 1.9 rim located posterior rectum 2.0 mm. No statistically significant difference found between measurements taken each level. Conclusion: Intraoperative endosonography can greatly enhance precision positioning canal.
