Recurrent tumour after radical pancreaticoduodenectomy may cause obstruction of the small bowel loop draining the liver. Roux-loop obstruction presents a particular therapeutic challenge, since the postsurgical anatomy usually prevents endoscopic access. Careful multidisciplinary discussion and multimodality preprocedure imaging are essential to accurately demonstrate the cause and anatomical location of the obstruction. Transhepatic or direct percutaneous stent placement should be possible in most cases, thereby avoiding long-term external biliary drainage. Gastropexy T-fasteners will secure the percutaneous access and reduce the risk of bile leakage. The static bile is invariably contaminated by gut bacteria, and systemic sepsis is to be expected. Enteral stents are preferable to biliary stents, and compound covered stents in a sandwich construction are likely to give the best long-term results. Transhepatic and direct percutaneous enteral stent insertion after jejunopexy is illustrated and the literature reviewed.
根治性胰十二指肠切除术后的复发性肿瘤可能导致肝脏引流的小肠环阻塞。Roux 袢梗阻提出了一个特殊的治疗挑战,因为术后解剖结构通常阻止了内镜进入。仔细的多学科讨论和多模式术前成像对于准确显示梗阻的原因和解剖位置至关重要。在大多数情况下,经肝或直接经皮支架放置应该是可能的,从而避免长期的外部胆道引流。胃固定 T 型钉将固定经皮通道并降低胆汁漏的风险。静态胆汁总是被肠道细菌污染,预计会发生全身败血症。肠内支架优于胆道支架,夹心结构的复合覆盖支架可能会获得最佳的长期效果。经肝和直接经皮空肠固定术后的肠内支架插入术进行了说明,并对文献进行了回顾。
