Endoscopic retrograde cholangiopancreatography (ERCP) is the procedure of choice for biliary decompression in patients with unresectable pancreatic cancer. However, it may be unsuccessful in 3 to 10% of cases. When ERCP is unsuccessful, the usual alternatives are percutaneous transhepatic biliary drainage or surgery. Recently, several authors have reported the use of EUS-guided biliary drainage in patients with malignant biliary obstructions, with acceptable success and complication rates. We describe three cases of unresectable pancreatic cancer associated with obstructive jaundice, treated by EUS-guided biliary drainage.
Three patients with unresectable pancreatic cancer, associated with obstructive jaundice, were included. ERCP was unsuccessful because of complete tumor obstruction of the distal common bile duct and papilla invasion. An EUS-guided rendezvous maneuver was attempted, without success. Then, EUS-guided choledochoduodenostomy, with a partially covered self-expanding metal stent, was performed in the same procedure. There were no early complications and the procedure was also clinically effective in relieving jaundice in all cases.
EUS-guided biliary drainage is a feasible alternative to percutaneous transhepatic biliary drainage or surgery in unresectable pancreatic cancer with obstructive jaundice when ERCP fails. However, the development of new specific instruments and studies comparing this procedure with percutaneous transhepatic biliary drainage and surgery are needed.
内镜逆行胰胆管造影术(ERCP)是无法切除的胰腺癌患者进行胆道减压的首选方法。然而,在3%至10%的病例中可能不成功。当ERCP不成功时,通常的替代方法是经皮经肝胆道引流或手术。最近,几位作者报道了在恶性胆道梗阻患者中使用超声内镜引导下胆道引流,成功率和并发症发生率均可接受。我们描述了3例无法切除的胰腺癌合并梗阻性黄疸患者,采用超声内镜引导下胆道引流治疗。
纳入3例无法切除的胰腺癌合并梗阻性黄疸患者。由于胆总管远端完全被肿瘤阻塞且乳头受侵,ERCP未成功。尝试进行超声内镜引导下会师操作,但未成功。然后,在同一操作中进行了超声内镜引导下胆总管十二指肠吻合术,并置入了部分覆膜自膨式金属支架。无早期并发症,该操作在所有病例中均有效缓解了黄疸。
当ERCP失败时,超声内镜引导下胆道引流是无法切除的胰腺癌合并梗阻性黄疸患者经皮经肝胆道引流或手术的可行替代方法。然而,需要开发新的专用器械,并开展将该操作与经皮经肝胆道引流及手术进行比较的研究。
