SEMS are associated with lower stent dysfunction, lower re-intervention rates, better survival, and higher patency time. Complications and costs showed no difference.
Background and study aims
Endoscopic removal of biliary stones has high success rates, ranging between 85 % to 95 %. Nevertheless, some stones may be challenging and different endoscopic methods have evolved. Papillary large balloon dilation after sphincterotomy is a widely used technique with success rates ranging from 68 to 90 % for stones larger than 15 mm. Cholangioscopy allows performing lithotripsy under direct biliary visualization, either by laser or electrohydraulic waves, which have similar success rate (80 % – 90 %). However, there is no study comparing these 2 techniques.
Patients and methods
From April 2014 to June 2016, 100 patients were enrolled and randomized in 2 groups, using a non-inferiority hypothesis: cholangioscopy + electrohydraulic lithotripsy (group 1) and endoscopic papillary large balloon dilation (group 2). The main outcome was complete stone removal. Adverse events were documented. Mechanical lithotripsy was not performed. Failure cases had a second session with crossover of the methods.
Results
The mean age was 56 years. 74 (75.5 %) patients were female. The initial overall complete stone removal rate was 74.5 % (77.1 % in group 1 and 72 % in group 2,
P
> 0.05). After second session the overall success rate achieved 90.1 %. Procedure time was significantly lower in group 2, – 25.2 min (CI95 % – 12.48 to – 37.91). There were no significant differences regarding technical success rate, radiologic exposure and adverse events.
Conclusion
Single-operator cholangioscopy-guided lithotripsy and papillary large balloon dilation are effective and safe approaches for removing complex biliary stones.
-In order to draw evidence-based recommendations concerning the management of autoimmune diseases of the liver, the Brazilian Society of Hepatology has sponsored a single-topic meeting in October 18th, 2014 at São Paulo. An organizing committee comprised of seven investigators was previously elected by the Governing Board to organize the scientific agenda as well as to select twenty panelists to make a systematic review of the literature and to present topics related to the diagnosis and treatment of autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis and their overlap syndromes. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript organized in topics, followed by the recommendations of the Brazilian Society of Hepatology.
We compared analgesic efficacy and degree of motor block induced by ropivacaine 0.1% (R 0.1) and 0.2% (R 0.2) vs. bupivacaine 0.2% (B 0. 2) after caudal anaesthesia in children. Total and free plasma concentrations were measured after caudal injection. Duration of caudal analgesia (median/range) was significantly shorter in group R 0.1 (1.7 h/0.2-6 h) than in group R 0.2 (4.5 h/1.7-6 h) or group B 0. 2 (4 h/1-6 h) (P<0.05). Motor block in the first 2 h postoperatively was significantly less for both ropivacaine groups compared with bupivacaine (P<0.05). Peak plasma concentrations after ropivacaine 0.2% were higher and protein binding lower than after bupivacaine 0.2% (P<0.05). We conclude that caudal analgesia with ropivacaine 0.1% is less effective and of shorter duration than that of ropivacaine 0.2%, whereas ropivacaine 0.2% provides pain relief similar to bupivacaine 0.2%. Motor block in the early postoperative period is less with ropivacaine than with bupivacaine.
Background and study aims
The first-line approach to anastomotic biliary stricture after orthotopic liver transplantation (OLTX) involves endoscopic retrograde cholangiopancreatography (ERCP). The most widely used technique is placement of multiple plastic stents, but discussions are ongoing on the benefits of fully-covered self-expandable metallic stents (FCEMS) in this situation. This study aimed to compare results from use of plastic and metal stents to treat biliary stricture after transplantation.
Patients and methods
Searches were performed in the Medline, EMBASE, SciELO/LILACS, and Cochrane databases, and only randomized studies comparing the two techniques were included in the meta-analysis.
Results
Our study included four randomized clinical trials totaling 205 patients. No difference was observed between the stricture resolution rate (RD: 0.01; 95 %CI [−0.08 – 0.10]), stricture recurrence (RD: 0.13; 95 %CI [−0.03 – 0.28]), and adverse events (RD: −0.10; 95 %CI [−0.65 – 0.44]) between the plastic and metallic stent groups. The metallic stent group demonstrated benefits in relation to the number of ERCPs performed (MD: −1.86; 95 %CI [−3.12 to −0.6]), duration of treatment (MD: −105.07; 95 %CI [−202.38 to −7.76 days]), number of stents used (MD: −10.633; 95 %CI [−20.82 to −0.44]), and cost (average $ 8,288.50 versus $ 18,580.00,
P
< 0.001).
Conclusions
Rates of resolution and recurrence of stricture are similar, whereas the number of ERCPs performed, number of stents used, duration of treatment, and costs were lower in patients treated with FCEMS, which shows that this device is a valid option for initial treatment of post-OLTX biliary stricture.
