Long-term studies evaluating self-expandable metal stents in patients who have unresectable malignant hilar biliary obstruction (UMHBO) after surgical reconstruction of the intestine remain inadequate. We developed a side-by-side (SBS) technique using a two-channel endoscope to place self-expandable metal stents in patients with UMHBO occurring after Billroth II reconstruction.
We validated the long-term outcomes obtained with this technique.
The study group comprised seven patients with UMHBO in whom we attempted to place metal stents by the SBS technique using a two-channel scope. The procedure was validated retrospectively.
The technical success rate was 86% and functional success rate was 100%. The median time to recurrent biliary obstruction (RBO) was 222 days (95% CI 4.9-439.1). Besides RBO, there were no other complications.
The SBS procedure performed using a two-channel scope is a safe and useful new technique for the treatment of UMHBO occurring after Billroth II reconstruction.
对于肠重建术后不可切除的恶性肝门胆管梗阻（UMHBO）患者，评估自膨式金属支架的长期研究仍然不足。我们开发了一种使用双通道内镜的并排（SBS）技术，将自膨式金属支架用于 Billroth II 重建后发生 UMHBO 的患者。
验证该技术获得的长期结果。
研究组包括 7 例 UMHBO 患者，我们试图通过使用双通道内镜的 SBS 技术放置金属支架。该程序进行了回顾性验证。
技术成功率为 86%，功能成功率为 100%。再发胆道梗阻（RBO）的中位时间为 222 天（95%CI 4.9-439.1）。除 RBO 外，无其他并发症。
使用双通道内镜进行的 SBS 手术是治疗 Billroth II 重建后发生 UMHBO 的一种安全且有用的新技术。
