分离远端胆管，并通过冷冻切片检查横切，确认没有恶性肿瘤。然后通过首先识别并横切距离Treitz韧带40厘米的近端空肠，将注意力转移到构建60厘米的Roux肢体上。完成侧侧吻合空肠空肠吻合术。通过先行方法将Roux肢体转移到肝门。
The distal bile duct was isolated and transected with a frozen section examination confirming the absence of malignancy. Attention was then shifted to constructing a 60 cm Roux limb by first identifying and transecting the proximal jejunum 40 cm from the ligamentum of Treitz. A side-to-side stapled jejunojejunostomy anastomosis was completed. The Roux limb was transposed toward the porta hepatis through an antecolic approach.
