“…A single plastic stent was compared with multiple plastic stents in one non-randomized study [64]. The remaining studies were all case series, of which 33 were retrospective[16,21-29,31,35-37,39,41-44,47,49-51,53-55,59,60,62,64] and 14 prospective in design[15,30,32,34,38,40,45,48,52,56-58,61,63]…”

Plastic or metal stents for benign extrahepatic biliary strictures: a systematic review

BackgroundBenign biliary strictures may be a consequence of surgical procedures, chronic pancreatitis or iatrogenic injuries to the ampulla. Stents are increasingly being used for this indication, however it is not completely clear which stent type should be preferred.MethodsA systematic review on stent placement for benign extrahepatic biliary strictures was performed after searching PubMed and EMBASE databases. Data were pooled and evaluated for technical success, clinical success and complications.ResultsIn total, 47 studies (1116 patients) on outcome of stent placement were identified. No randomized controlled trials (RCTs), one non-randomized comparative studies and 46 case series were found. Technical success was 98,9% for uncovered self-expandable metal stents (uSEMS), 94,8% for single plastic stents and 94,0% for multiple plastic stents. Overall clinical success rate was highest for placement of multiple plastic stents (94,3%) followed by uSEMS (79,5%) and single plastic stents (59.6%). Complications occurred more frequently with uSEMS (39.5%) compared with single plastic stents (36.0%) and multiple plastic stents (20,3%).ConclusionBased on clinical success and risk of complications, placement of multiple plastic stents is currently the best choice. The evolving role of cSEMS placement as a more patient friendly and cost effective treatment for benign biliary strictures needs further elucidation. There is a need for RCTs comparing different stent types for this indication.

“…The stent covering limits potential mucosal ingrowth and hyperplasia, factors which lead to occlusion and difficult retrieval in uncovered metallic stents. 37,38 These stents, however, do require retrieval via endoscopy, which as stated before is extremely technically challenging when having to navigate the altered post-surgical anatomy. We have found success at our institution using a rendezvous procedure for retrieval, where percutaneous access is maintained with a small caliber 8 F external biliary drain after initial stent placement.…”

Postoperative bilioenteric anastomotic strictures are encountered in a significant number of patients after primary biliary repair, hepatopancreaticobiliary tumor resection, and liver transplantation. Due to difficulties with repeat surgery and endoscopic access, percutaneous dilation has become the accepted treatment in these cases. While the overall paradigm of percutaneous access, balloon dilation, and catheter stenting remains consistent, institutional protocols differ in several technical variables including balloon sizes, inflation techniques, catheter sizing, and overall time course of treatment, amongst others. The current review aims to discuss various treatment protocols and their relative efficacy, as well as touch on emerging techniques.

“…However, despite initial promising results and high primary technical success rates [48,49], long-term results of benign biliary stricture treatments by metallic stents have been tempered by high rates of late re-occlusion [50]. On the other hand, retrievable covered stent seems to be a good alternative to shorten treatment duration compared to interposition of an internal-external catheter.…”

Benign biliary obstruction: is treatment with the Wallstent advisable?

Abstract: Results of stent placement for treatment of benign biliary strictures are not encouraging. However, the patient population is too limited to allow final conclusions.
