Liver transplantation for bile duct injury after open and laparoscopic cholecystectomy.

ABSTRACT: BACKGROUND: Bile duct injury (BDI) after cholecystectomy is a serious complication. In a small subset of patients with BDI, failure of surgical or non-surgical management might lead to acute or chronic liver failure. The aim of this study was to review the indications and outcome of liver transplantation (LT) for BDI after open and laparoscopic cholecystectomy. METHODS: Patients with BDI after cholecystectomy who were on the waiting list for LT between January 1987 and December 2010 were identified from LT centres in Spain. A standardized questionnaire was sent to each unit for extraction of data on diagnosis, previous treatments, indication and outcome of LT for BDI. RESULTS: Some 27 patients with BDI after cholecystectomy in whom surgical and non-surgical management for BDI failed were scheduled for LT over the 24-year interval. Emergency LT for acute liver failure was indicated in seven patients, all after laparoscopic cholecystectomy. Two patients died while on the waiting list and only one patient survived more than 30 days after LT. Elective LT for secondary biliary cirrhosis after a failed hepaticojejunostomy was performed in 13 patients after open and seven after laparoscopic cholecystectomy. One patient from the elective transplantation group died within 30 days of LT. The estimated 5-year overall survival rate was 68 per cent. CONCLUSION: Emergency LT for acute liver failure was more common in patients with BDI after laparoscopic cholecystectomy, and associated with a poor outcome.

Project description:BackgroundEndoscopic retrograde cholangiography (ERC) with stone extraction and papillotomy with subsequent laparoscopic cholecystectomy-the two-step approach-is the standard treatment of common bile duct stones in many countries. However, ERC is associated with a high risk of complications and more than half of patients require multiple ERCs. Meta-analyses of randomised clinical trials find no major differences of the two-step approach in comparison with laparoscopic cholecystectomy with intraoperative laparoscopic stone clearance-the one-step approach. Currently, there are insufficient data to ascertain superiority.MethodsThe preGallstep trial is an investigator-initiated, multicentre randomised feasibility and pilot clinical trial with blinded outcome assessment. Eligible patients are patients with common bile duct stones (identified by magnetic resonance cholagiopancreatography), age 18 years or above with the possibility to perform both interventions within a reasonable time. We intent to randomise 150 participants allocated 1:1. The experimental intervention is the one-step approach. This consists of laparoscopic common bile duct exploration plus laparoscopic cholecystectomy. The control intervention is the two-step approach which consists of ERC plus sphincterotomy (first step) and subsequent laparoscopic cholecystectomy (second step). Feasibility outcomes include the proportion of eligible patients not wanting to participate, reasons for rejection to participate, difficulties during the informed consent procedure, difficulties with randomisation, difficulties with data management, difficulties with blinding patient charts and forms and difficulties with maintaining blinding for the outcome assessors. The primary pilot outcome is the proportion of participants with at least one postoperative complication according to the Clavien-Dindo score grade II and above until 90 days after randomisation. This outcome will be used for a future sample size calculation of a larger pragmatic trial. Further, a range of clinical explorative outcomes will be assessed.DiscussionAs no sample size is estimated in this trial, there is a risk of wrongly assessing the effect on the patient-related outcome. The surgical procedures cannot be blinded. However, blinding will be employed in all other aspects of the trial, including the establishment of a blinded outcome adjudication committee with three independent assessors. Heterogeneity in screening, randomisation, diagnostics, treatment procedures, interventions and follow-up across trial sites may cause challenges in conducting a larger pragmatic trial. To monitor inter-site differences, we have implemented a central data monitoring scheme.Trial registrationClinicalTrials.gov identification: NCT04801238 , Registered on 16 March 2021.

Project description:BackgroundRaoultella Planticola is a facultative anaerobic, gram-negative, water- and soil-dwelling rod bacterium rarely reported as a cause of human disease. However, the number of reported R. planticola infections is growing, without a concomitant increase in research on the microbe or its pathogenesis. Previous genomic studies demonstrating genetic similarities between R. planticola and Klebsiella pneumoniae suggest that capsule biosynthesis, mucoid phenotype, biofilm production, and lipopolysaccharide (endotoxin) synthesis may all be potential virulence factors of R. planticola. We present a unique case of R. planticola infection of the biliary tract 5 years after biliary surgery in a patient with no previously documented risk factors. We also use in silico techniques to predict virulence factors of R. planticola.Case presentationThis case report is the first to discuss a R. planticola infection in the biliary tract of late onset post-surgery (5 years) in a Caucasian patient with no previously documented risk factors.ConclusionsAn in-depth search of the current literature did not yield other similar cases of R. planticola infections. Moreover, to the best of our knowledge, our case is the first case of R. planticola isolated from post-endoscopic retrograde cholangiopancreatography (ERCP) as part of biliary sepsis not associated with gastroenteritis. The late onset of the infection in our patient and the results of the in silico analysis suggest that R. planticola may have survived exposure to the host immune system through the creation of an intracellular biofilm or in a non-culturable but viable state (NCBV) for the 5-year period. The in silico analysis also suggests that biofilms, enterobactin, and mucoid phenotype may play a role in the pathogenesis of R. planticola. However, further research is needed to illuminate the significance of pili, capsule biosynthesis, and lipopolysaccharide (LPS) in the virulence of R. planticola. Lastly, as our patient did not have any risk factors previously associated with R. planticola, we suggest that biliary tract stricture, cholecystitis, and prior surgery may be possible novel risk factors.
