AbstractTreatment of malignant biliary obstruction (MBO) requires the coordination of multiple specialties, including oncologists, surgeons, gastroenterologists, and interventional radiologists. If the tumor is resectable, surgical candidates can usually proceed to surgery without preoperative biliary drainage. For patients who undergo biliary drainage, endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) combined with biliary stenting are techniques with comparable technical success and mortality, each with distinct advantages and risks. Advances in endoscopic ultrasound allow drainage in patients with challenging anatomy. There are a multitude of devices used for biliary decompression. Self-expanding metal stents (SEMS), with longer patency rates, are in most instances preferred over plastic stents for MBO, especially in patients with life expectancy more than 3 to 4 months. Advantages of covered SEMS versus uncovered SEMS remain controversial as covered stents can prevent tumor ingrowth but at the expense of potential increase in stent migrations. Extra-anatomic biliary drainage using lumen-apposing metal stents is an emerging technique which shows promise when conventional ERCP fails. It is imperative to understand these techniques when tailoring a treatment strategy. The goal of this article is to discuss a multidisciplinary approach for MBO to promote comprehensive care using case examples to highlight essential principles.

Distal Malignant Biliary Obstruction

Distal malignant biliary obstruction is caused by various malignant diseases that require biliary drainage. In patients with operable situations, preoperative biliary drainage is required to control jaundice and cholangitis until surgery. In view of tract seeding, endoscopic biliary drainage is the first choice. Since neoadjuvant therapies are being developed, the time to surgery is increasing, especially in pancreatic cancer cases. Therefore, it requires long stent patency. Recently, preoperative biliary drainage using self-expandable metal stents has been reported as a useful modality to secure long stent patency. In patients with unresectable distal malignant biliary obstruction, self-expandable metal stent is the first choice for maintaining long stent patency. Although there are many comparison studies between a covered and an uncovered self-expandable metal stent, their use is still controversial. Recently, endoscopic ultrasound-guided biliary drainage has been performed as an alternative treatment. The clinical success and stent patency are favorable. We should take into consideration that both endoscopic retrograde cholangiopancreatography-guided biliary drainage and endoscopic ultrasound-guided biliary drainage have advantages and disadvantages and chose the drainage method depending on the patient’s situation or the expertise of the endoscopist. Here, we discuss the current status of endoscopic biliary drainage in patients with distal malignant biliary obstruction.

Distal Malignant Biliary Obstruction

Background Self-expanding metal stents (SEMSs) are recommended in unresectable distal malignant biliary obstruction. However, problems with dysfunction and migration of these stents are not negligible. We aimed to investigate the effectiveness and safety of a new 12-Fr plastic stent. Methods In an observational, prospective study, all consecutive patients who underwent biliary stenting with the 12-Fr stent were considered (index group). Referent groups were a historical cohort, matched by sex, etiology, and metastatic status, including patients with 10-Fr plastic stents and with fully covered and uncovered SEMSs (FCSEMSs and UCSEMSs). Outcomes were stent patency, recurrent biliary obstruction (RBO), technical success, 30-day mortality and adverse events. A post-procedure examination of removed stents was done. Results 72 patients (median age 66, range 32 – 94 years, 50 % men) were included (24 index, 48 referents). There were no differences in median stent patency time (P = 0.684). RBO was significantly lower with the 12-Fr compared with the 10-Fr profile stent (50 % vs. 81.3 %, P = 0.04), but no difference was found compared with the FCSEMSs (50 % vs. 43.8 %, P = 0.698). Technical success was 100 %, with no differences in 30-day mortality P = 0.105). The adverse events rate was 4.2 % for both groups (index n = 1, referents n = 2). Of 11 removed 12-Fr plastic stents suspected to be dysfunctional, 7 (64 %) were still patent. Conclusions This new 12-Fr plastic stent could be an effective and cheaper alternative to SEMSs in distal malignant biliary obstruction.

Background and Aims. For distal malignant biliary obstruction in cases with short life expectancy, occlusion of plastic stents (PSs) does not usually occur before death, and the application of such a procedure is considered adequate from the viewpoint of cost-effectiveness. Methods and Setting. A new commercially available DLS with side holes, a conventional DLS, and, uncovered self-expanding metal stents (SEMSs) were retrospectively evaluated in patients with jaundice due to unresectable distal malignant biliary obstruction. Results. A total of 64 patients received endoscopic biliary stenting (23 patients with the new DLS, 24 patients with conventional DLS, and 17 patients with uncovered SEMS) from December 2002 to August 2009. Median patency time was found to be 198 days for the new DLS group and 99 days for the conventional DLS group, revealing a significant difference between devices. There was, however, no significant difference in median patency time between the new DLS and the uncovered SEMS (198 days versus 344 days). Conclusion. The new DLS is efficient and safe and may be considered the first choice for unresectable distal malignant obstruction in cases with short life expectancy.
