Biliary drainage in patients with unresectable, malignant obstruction where ERCP fails: endoscopic ultrasonography-guided choledochoduodenostomy versus percutaneous drainage.

Background: Endoscopic retrograde cholangiopancreatography may fail because of malignant involvement of the second portion of the duodenum and the major papilla. Alternatives include percutaneous transhepatic biliary drainage (PTBD) or surgical bypass. Endoscopic ultrasonography-guided choledochoduodenostomy (EUS-CD) has been reported as an alternative. Objective: To prospectively compare EUS-CD and PTBD in patients with unresectable malignant biliary obstruction. Design: Prospective and randomized study. Setting: Tertiary center. Main Outcome Measurements: Success and efficacy comparison EUS-CD with PTBD. Results: Twenty-five subjects were randomized (13 EUS-CD and 12 PTBD). Mean age was 67 years (SD, 11.9). The 2 groups were similar before intervention in terms of quality of life [EUS-CD (58.3) vs. PTBD (57.8); P=0.78], total bilirubin (16.4 vs. 17.2; P=0.7), alkaline phosphatase (539 vs. 518; P=0.7), and gamma-glutamyl transferase (554.3 vs. 743.5; P=0.56). All procedures were technically and clinically successful in both groups. At 7-day follow-up there was a significant reduction in total bilirubin in both the groups (EUS-CD, 16.4 to 3.3; P=0.002 and PTBD, 17.2 to 3.8; P=0.01), although no difference was noted comparing the 2 groups (EUS-CD to PTBD; 3.3 vs. 3.8; P=0.2). There was no difference between the complication rates in the 2 groups (P=0.44), EUS-CD (2/13; 15.3%) and PTBD (3/12; 25%). Costs were similar in the 2 groups also (

Endoscopic approach for management of biliary strictures in liver transplant recipients: A systematic review and meta-analysis

Abstract Objective. Describe a case series of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (EUS-CD) associated with duodenal self-expandable metal stents (SEMS) placement using solely the linear echoendoscope in seven patients with obstructive jaundice and duodenal obstruction due to unresectable periampullary cancer. Material and methods. EUS-CD in the first portion of the duodenum, associated with duodenal SEMS placement was performed in seven patients with unresectable periampullary cancer with obstructive jaundice and invasive duodenal obstruction. Laboratory tests and clinical follow-up were performed until patients death. The procedure was performed by an experienced endoscopist under conscious sedation. The puncture position was chosen based on EUS evaluation, at the common bile duct (CBD) above the tumor, through the distal part of the duodenal bulb. After that, the needle was withdrawn and a wire-guided needle knife was used to enlarge the site puncture in the duodenal wall. Then, a partially covered SEMS was passed over the guide, through the choledochoduodenal fistula. Duodenal SEMS placement was performed during the same endoscopic procedure. Results. The procedure was performed in seven patients, ranging between 34 and 86 years. Technical success of EUS-CD, by the stent placement, occurred in 100% of the cases. There were no early complications. Duodenal SEMS placement was effective in 100% of the cases that remained alive after a follow-up of 7 and 30 days. Conclusion. The results suggest therapeutic EUS one-step procedure drainage as an alternative for these patients, with good clinical success, feasible technique and safety.

Management of Common Bile Duct Stones in Cirrhotic Patients with Coagulopathy: A Comparison of Supra-Papillary Puncture and Standard Cannulation Technique

we did not encounter any procedural complications, the study cohort was made up of only 20 patients. Several larger series on EUS-guided PFC drainage have reported bleeding, perforation, infection, and stent migration as potential complications associated with the procedure. This study demonstrates that EUS-guided drainage is a minimally invasive, safe, and highly effective technique for the management of symptomatic PFCs after distal pancreatectomy. When the technology and technical expertise are available, EUS should be considered the first-line treatment modality for the management of these patients.

Surgical or endoscopic management for post-ERCP large transmural duodenal perforations: a randomized prospective trial

The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications. Aim The aim of this article is to compare different endoscopic techniques to treat post-liver transplantation biliary strictures. Methods The search was carried out on MEDLINE, EMBASE, Scielo-LILACS and Cochrane Library databases through June 2015. A total of 1100 articles were retrieved. Ten clinical trials were analyzed, and seven were included in the meta-analysis. Conclusions The endoscopic treatment of AS was equally effective when compared the use of fully covered self-expandable metal stents (FCSEMS) vs. plastic stents, but the use of FCSEMS was associated with a lower complication risk. The treatment of AS with balloon dilation or balloon dilation associated with plastic stents presented similar results. Deceased donor liver transplantation reduced the risk of biliary stenosis and the endoscopic treatment in these patients was more effective when compared with Living donor liver transplantation.
