Abstract
ZusammenfassungBiliäre Komplikationen stellen häufige Komplikationen nach Leberchirurgie dar und tragen wesentlich zur postoperativen Morbidität und Mortalität bei. Den größten Anteil dieser
machen Gallengangsleckagen und -strikturen aus, wobei die Leckagen nach Cholezystektomie und Leberresektion dominieren und die Strikturen ein wesentliches Problem nach
Lebertransplantationen darstellen. Patienten nach orthotoper Lebertransplantation stellen besonders vulnerable Patienten dar, deren biliäre Komplikationen von denen nach
Cholezystektomie und Leberresektion differieren und niederschwellig sowie mit größter Vorsicht behandelt werden müssen. Mit der endoskopischen retrograden Cholangiografie steht ein
exzellentes Verfahren zur Behandlung dieser Komplikationen zur Verfügung. Die therapeutischen Möglichkeiten beinhalten die endoskopische Sphinkterotomie, die Anlage von Prothesen
und Dilatationen. Mittels dieser Verfahren können Erfolgsraten in bis zu 90% der Fälle erreicht werden. Bei Hepatikojejunostomien bestehen alternative Interventionsmöglichkeiten
wie die ballon- oder motorunterstützte antegrade Enteroskopie, die perkutan-transhepatische Cholangiodrainage oder mit zunehmendem Einsatz die endosonografisch gestützten
Verfahren.

Duct-to-duct biliary reconstruction with or without an Intraductal Removable Stent in Liver Transplantation: The BILIDRAIN-T Multicentric Randomized Trial. JHEP Rep 2022; 4:100530. [PMID: 36082313 PMCID: PMC9445377 DOI: 10.1016/j.jhepr.2022.100530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 05/26/2022] [Accepted: 06/15/2022] [Indexed: 11/21/2022] Open
Abstract
Background & Aims Biliary complications (BC) following liver transplantation (LT) are responsible for significant morbidity. No technical procedure during reconstruction has been associated with a risk reduction of BC. The placement of an intraductal removable stent (IRS) during reconstruction followed by its endoscopic removal showed feasibility and safety in a preliminary study. This multicentric randomised controlled trial aimed at evaluating the impact of an IRS on BC following LT. Methods This multicentric randomised controlled trial was conducted in 7 centres from April 2015 to February 2019. Randomisation was done during LT when a duct-to-duct anastomosis was confirmed with at least 1 of the stump diameters ≤7 mm. In the IRS group, a custom-made segment of a T-tube was placed into the bile duct to act as a stake during healing and was removed endoscopically 4 to 6 months post LT. The primary endpoint was the incidence of BC (fistulae and strictures) within 6 months post LT. The secondary criteria were complications related to the IRS placement or extraction, including endoscopic retrograde cholangio-pancreatography (ERCP)-related complications. Results In total, 235 patients were randomised: 117 in the IRS group and 118 in the control group. BC occurred in 31 patients (26.5%) in the IRS group vs. 24 (20.3%) in the control group (p = 0.27), including 16 (13.8%) and 15 (12.8%) strictures, respectively. IRS migration occurred in 24 patients (20.5%), cholangitis in 1 (0.9%), acute pancreatitis in 2 (1.8%), and difficulty during endoscopic extraction in 19 (19.4%). No predictive factor for BC was identified. Conclusions IRS does not prevent BC after LT and may require specific endoscopic expertise for removal. Trial registration number (ClinicalTrials.gov) NCT02356939 (https://clinicaltrials.gov/ct2/show/NCT02356939?term=NCT02356939&draw=2&rank=1). Lay summary Liver transplantation is a life-saving treatment for many patients with end-stage liver disease. However, it can be associated with complications involving the bile duct reconstruction. Herein, the placement of a specific stent called an intraductal removable stent was trialled as a way of reducing bile duct complications in patients undergoing liver transplantation. Unfortunately, it did not help preventing such complications. An IRS was placed during biliary reconstruction in bile ducts ≤7 mm; ERCP removal was 4–6 months post LT. The primary endpoint was the incidence of biliary complications (fistulae and strictures) within 6 months post LT. Biliary complications occurred in 31 patients (26.5%) in the IRS vs. 24 (20.3%) in the control group (p = 0.27). IRS migrated in 24 (20.5%) patients, and extraction was difficult in 19 (19.4%). No predictive factor for biliary complications was identified.

A Complex In Vitro Degradation Study on Polydioxanone Biliary Stents during a Clinically Relevant Period with the Focus on Raman Spectroscopy Validation. Polymers (Basel) 2022; 14:polym14050938. [PMID: 35267761 PMCID: PMC8912347 DOI: 10.3390/polym14050938] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 02/18/2022] [Accepted: 02/23/2022] [Indexed: 02/06/2023] Open
Abstract
Biodegradable biliary stents are promising treatments for biliary benign stenoses. One of the materials considered for their production is polydioxanone (PPDX), which could exhibit a suitable degradation time for use in biodegradable stents. Proper material degradation characteristics, such as sufficient stiffness and disintegration resistance maintained for a clinically relevant period, are necessary to ensure stent safety and efficacy. The hydrolytic degradation of commercially available polydioxanone biliary stents (ELLA-CS, Hradec Králové, Czech Republic) in phosphate-buffered saline (PBS) was studied. During 9 weeks of degradation, structural, physical, and surface changes were monitored using Raman spectroscopy, differential scanning calorimetry, scanning electron microscopy, and tensile and torsion tests. It was found that the changes in mechanical properties are related to the increase in the ratio of amorphous to crystalline phase, the so-called amorphicity. Monitoring the amorphicity using Raman spectroscopy has proven to be an appropriate method to assess polydioxanone biliary stent degradation. At the 1732 cm−1 Raman peak, the normalized shoulder area is less than 9 cm−1 which indicates stent disintegration. The stent disintegration started after 9 weeks of degradation in PBS, which agrees with previous in vitro studies on polydioxanone materials as well as with in vivo studies on polydioxanone biliary stents.

A New Biodegradable Stent to Improve the Management of Biliary Strictures in Pediatric Split Liver Transplantation. Cardiovasc Intervent Radiol 2022; 45:867-872. [PMID: 35199216 DOI: 10.1007/s00270-022-03083-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Accepted: 01/07/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE Cholestasis due to benign biliary strictures is the most common biliary complication after pediatric split liver transplantation (SLT), decreasing graft survival, but consensus about its management lacks. Percutaneous transhepatic cholangiography, bilioplasty and internal-external biliary drainage (IEBD) are standard treatments. The aim of this report is to present the preliminary experience with a new biodegradable biliary stent in the management of post-SLT biliary strictures. MATERIALS AND METHODS Between September 2020 and April 2021, SLT patients with a single anastomotic benign biliary stricture underwent percutaneous transhepatic implantation of an innovative 10F helical-shaped biodegradable biliary stent, featuring a slow degradation profile, in addition to the standard treatment with bilioplasty and IEBD. The device is unique and the first to be CE-marked for the use in this indication. RESULTS Six pediatric patients (4 males; median age 8.6 years, interquartile range 3.7 years) underwent percutaneous stent implantation, without complications nor clinical cholestasis during a median follow-up of 271 days (IQR 120.25). Stent dislodgement occurred in one case. CONCLUSION Preliminary data suggest that implantation of a new biodegradable biliary stent may be considered in the management of post-SLT cholestasis in pediatric patients. Some technical tips are useful during implantation. This device may prolong biliary drainage, potentially relieving the discomfort of long-term IEBD.

Abstract
BACKGROUND With the increasing use of extended-criteria donor organs, the interest around T-tubes in liver transplantation (LT) was restored whilst concerns regarding T-tube-related complications persist.
AIM To describe insertion and removal protocols implemented at our institution to safely use pediatric rubber 5-French T-tubes and subsequent outcomes in a consecutive series of adult patients.
METHODS Data of consecutive adult LT patients from brain-dead donors, treated from March 2017 to December 2019, were collected (i.e., biliary complications, adverse events, treatment after T-Tube removal). Patients with upfront hepatico-jejunostomy, endoscopically removed T-tubes, those who died or received retransplantation before T-tube removal were excluded.
RESULTS Seventy-two patients were included in this study; T-tubes were removed 158 d (median; IQR 128-206 d) after LT. In four (5.6%) patients accidental T-tube removal occurred requiring monitoring only; in 68 (94.4%) patients Nelaton drain insertion was performed according to our protocol, resulting in 18 (25%) patients with a biliary output, subsequently removed after 2 d (median; IQR 1-4 d). Three (4%) patients required endoscopic retrograde cholangiopancreatography (ERCP) due to persistent Nelaton drain output. Three (4%) patients developed suspected biliary peritonitis, requiring ERCP with sphincterotomy and nasobiliary drain insertion (only one revealing contrast extravasation); no patient required percutaneous drainage or emergency surgery.
CONCLUSION The use of pediatric rubber 5-French T-tubes in LT proved safe in our series after insertion and removal procedure refinements.

Percutaneous Balloon Dilatation for Hepaticojejunostomy Stricture Following Paediatric Liver Transplantation: Long-Term Results of an Institutional "Three-Session" Protocol. Cardiovasc Intervent Radiol 2021; 45:330-336. [PMID: 34796374 DOI: 10.1007/s00270-021-03000-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 10/26/2021] [Indexed: 12/16/2022]
Abstract
PURPOSE The aim of this study was to report the long-term results of an institutional protocol of percutaneous biliary balloon dilatation (PBBD) on paediatric patients with benign anastomotic stricture after liver transplantation. As a secondary objective, we evaluated risk factors associated with post-treatment re-stricture. MATERIALS AND METHODS Fourteen paediatric, post-liver transplant patients with benign anastomotic stricture of Roux-en-Y hepaticojejunostomy were included. All patients underwent the same treatment protocol of three PBBD procedures with 15-day intervals. Clinical outcome was analysed using the Terblanche classification. Primary patency rate was assessed with the Kaplan-Meier test. RESULTS All patients had an initial successful result (Terblanche grade, excellent/good) after PBBD. At the end of the follow-up time of 35.7 ± 21.1 months (CI95%, 23.5-47.9), 10 patients persisted with excellent/good grading, while the remaining 4 had re-stricture, all of the latter occurring within the first 19 months. Patency rate after percutaneous treatment at 1, 3, and 5 years were 85.7%, 70%, and 70%, respectively. History of major complication after liver transplantation was associated with 5 times higher risk of re-stricture, HR 5.48 [95% CI, 2.18-8.78], p = 0.018. CONCLUSION In paediatric patients with benign anastomotic stricture of hepaticojejunostomy after liver transplantation, the "Three-session" percutaneous biliary balloon dilatation protocol is associated with a high rate of long-term success. In this limited series, the history of post-liver transplant major complication, defined as complications requiring a reintervention under general anaesthesia or advanced life support, seems to be an independent risk factor for stricture recurrence.

Abstract
PURPOSE To investigate clinical outcomes and safety of extraluminal recanalization for duct-to-duct anastomotic obstruction after living donor liver transplantation (LDLT). MATERIALS AND METHODS Extraluminal recanalization was performed as a salvage procedure after failure of intraluminal cannulation in eight patients who underwent percutaneous transhepatic treatment of duct-to-duct anastomotic obstruction 11.0 ± 5.27 months after LDLT between October 2012 and April 2019. Technical details, safety, and outcomes of extraluminal recanalization were investigated. RESULTS Total ten sessions of extraluminal recanalization were performed in the eight patients with the stiff backend of a 0.035 inch hydrophilic guide wire, 22-gauge Chiba needle, or Colapinto needle. Percutaneous common bile duct access was performed in three sessions to obtain a straight course for the puncture. There was one instance of subcapsular and intraparenchymal hematoma requiring placement of an additional drainage catheter and conservative treatment. During a follow-up period ranging from 18.4 to 100.7 months, the drainage catheter was removed in seven of the eight patients, including three patients who had recurrent stricture requiring repeat percutaneous treatment and one who underwent a routine change of an endoscopic retrograde biliary drainage catheter. CONCLUSIONS Extraluminal recanalization can be an effective and safe salvage procedure after failed intraluminal cannulation of duct-to-duct anastomotic obstruction in LDLT.
