Project description:BackgroundBile 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.MethodsPatients 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.ResultsSome 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.ConclusionEmergency LT for acute liver failure was more common in patients with BDI after laparoscopic cholecystectomy, and associated with a poor outcome.

Project description:BackgroundIatrogenic bile duct injury (IBDI) is a challenging surgical complication. IBDI management can be guided by artificial intelligence models. Our study identified the factors associated with successful initial repair of IBDI and predicted the success of definitive repair based on patient risk levels.MethodsThis is a retrospective multi-institution cohort of patients with IBDI after cholecystectomy conducted between 1990 and 2020. We implemented a decision tree analysis to determine the factors that contribute to successful initial repair and developed a risk-scoring model based on the Comprehensive Complication Index.ResultsWe analyzed 748 patients across 22 hospitals. Our decision tree model was 82.8% accurate in predicting the success of the initial repair. Non-type E (p < 0.01), treatment in specialized centers (p < 0.01), and surgical repair (p < 0.001) were associated with better prognosis. The risk-scoring model was 82.3% (79.0-85.3%, 95% confidence interval [CI]) and 71.7% (63.8-78.7%, 95% CI) accurate in predicting success in the development and validation cohorts, respectively. Surgical repair, successful initial repair, and repair between 2 and 6 weeks were associated with better outcomes.DiscussionMachine learning algorithms for IBDI are a novel tool may help to improve the decision-making process and guide management of these patients.

Project description:BackgroundBile duct injury (BDI) is still a major worrisome complication that is feared by all surgeons undergoing cholecystectomy. The overall incidence of biliary duct injuries falls between 0.2 and 1.3%. BDI classification remains an important method to define the type of injury conducted for investigation and management. Recently, a Consensus has been taken to define BDI using the ATOM classification. Early management brings better results than delayed management. The current perspective in biliary surgery is the laparoscopic role in diagnosing and managing BDI. Diagnostic laparoscopy has been conducted in various entities for diagnostic and therapeutic measures in minor and major BDIs.Methods35 cases with iatrogenic BDI following cholecystectomy (after both open and laparoscopic approaches) both happened in or were referred to Alexandria Main University Hospital surgical department from January 2019 till May 2022 and were analyzed retrospectively. Patients were classified according to the ATOM classification. Management options undertaken were mentioned and compared to the timing of diagnosis, and the morbidity and mortality rates (using the Clavien-Dindo classification).Results35 patients with BDI after both laparoscopic cholecystectomy (LC) (54.3%), and Open cholecystectomy (OC) (45.7%) (20% were converted and 25.7% were Open from the start) were classified according to ATOM classification. 45.7% were main bile duct injuries (MBDI), and 54.3% were non-main bile duct injuries (NMBDI), where only one case 2.9% was associated with vasculobiliary injury (VBI). 28% (n = 10) of the cases were diagnosed intraoperatively (Ei), 62.9% were diagnosed early postoperatively (Ep), and 8.6% were diagnosed in the late postoperative period (L). LC was associated with 84.2% of the NMBDI, and only 18.8% of the MBDI, compared to OC which was associated with 81.3% of the MBDI, and 15.8% of the NMBDI. By the Clavien-Dindo classification, 68.6% fell into Class IIIb, 20% into Class I, 5.7% into Class V (mortality rate), 2.9% into Class IIIa, and 2.9% into Class IV. The Clavien-Dindo classification and the patient's injury (type and time of detection) were compared to investigation and management options.ConclusionManagement options should be defined individually according to the mode of presentation, the timing of detection of injury, and the type of injury. Early detection and management are associated with lower morbidity and mortality. Diagnostic Laparoscopy was associated with lower morbidity and better outcomes. A proper Reporting checklist should be designed to help improve the identification of injury types.

Project description:Bile duct injury (BDI) is a severe complication following cholecystectomy. Early recognition and treatment of BDI has been shown to reduce costs and improve patients' quality of life. The aim of this study was to assess the effect and cost-effectiveness of routine versus selective intraoperative cholangiography (IOC) in cholecystectomy. A systematic review and meta-analysis, combined with a health economic model analysis in the Swedish setting, was performed. Costs per quality-adjusted life-year (QALY) for routine versus selective IOC during cholecystectomy for different scenarios were calculated. In this meta-analysis, eight studies with more than 2 million patients subjected to cholecystectomy and 9000 BDIs were included. The rate of BDI was estimated to 0.36 per cent when IOC was performed routinely, compared with to 0.53 per cent when used selectively, indicating an increased risk for BDI of 43 per cent when IOC was used selectively (odds ratio 1.43, 95 per cent c.i. 1.22 to 1.67). The model analysis estimated that seven injuries were avoided annually by routine IOC in Sweden, a population of 10 million. Over a 10-year period, 33 QALYs would be gained at an approximate net cost of €808 000 , at a cost per QALY of about €24 900. Routine IOC during cholecystectomy reduces the risk of BDI compared with the selective strategy and is a potentially cost-effective intervention.

Project description:ObjectivesLong-term results of hepaticojejunostomy (HJ) for complex bile duct injury (BDI) remain under-reported. The objective of this study was to assess short-term and long-term outcomes of HJ for post-cholecystectomy BDI.MethodsThis was a retrospective cohort study and included patients who underwent Roux-en-Y HJ for BDI (n = 87). Short-term (90-day) and long-term morbidity and mortality were assessed.ResultsAt presentation, 42 (48.2%) patients had E3 or E4 BDI, 27 (31%) patients had vascular injury, and liver resection was performed in 12 (13.7%) patients. The 90-day morbidity was 51.7% (n = 45), and the 90-day mortality was 2.3% (n = 2). The long-term mortality was 3.4% (n = 3). The 10-year estimated stricture-free survival was 95%. The 10-year estimated overall survival rate was 100% in patients who underwent major hepatectomy and 91% in patients who did not. The 10-year estimated overall survival rate was 100% in patients with vasculobiliary injury and was not reached in patients without vascular injury.ConclusionsVascular injury with proximal BDI is not uncommon. Excellent long-term outcomes might be achieved with Roux-en-Y HJ for BDI with vascular injury and in patients requiring liver resection.

Project description:Backgrounds/aimsIn the absence of national registry of laparoscopic cholecystectomy (LC) or its complications, it is impossible to determine incidence of bile duct injury (BDI) in India. We conducted an e-survey among practicing surgeons to determine prevalence and management patterns of BDI in India. Our hypothesis was that majority of surgeons would have experienced a BDI during LC despite large experience and that most surgeons who have a BDI tend to manage it themselves.MethodsAn 18-question e-survey of practicing laparoscopic surgeons in India was done.Results278/727 (38%) surgeons responded. 240/278 (86%) respondents admitted to a BDI during LC and 179/230 (78%) affirmed to more than one BDI. A total of 728 BDIs were reported. 36/230 (15%) respondents experienced their first BDI even after ＞10 years of practice and 40% had their first BDI even after having performed ＞100 LCs. 161/201 (80%) of the respondents decided to manage the BDI themselves, including 56/99 (57%) non-biliary surgeons and 44/82 (54%) surgeons working in non-biliary center. 37/201 (18%) respondents admitted to having a mortality arising out of a BDI; the mortality rate of BDI was 37/728 (5%) in this survey. Only 13/201 (6%) respondents have experienced a medico-legal case related to a BDI during LC.ConclusionsPrevalence of BDI is high in India and occurs despite adequate experience and volume. Even inexperienced non-biliary surgeons working in non-biliary centers attempt to repair the BDI themselves. BDI is associated with significant mortality but litigation rates are fortunately low in India.

Project description:Biliary complications are still a major cause for morbidity and mortality after liver transplantation (LT). Ischemia/reperfusion injury (IRI) leads to disruption of the biliary epithelium. We introduce a novel model to study the effect of IRI on human cholangiocytes using extrahepatic cholangiocyte organoids (ECOs). Extrahepatic bile duct tissue was collected during LT at static cold storage and after reperfusion (n = 15); gallbladder tissue was used for controls (n = 5). ECOs (n = 9) were cultured from extrahepatic biliary tissue, with IRI induced in an atmosphere of 95% air (nitrogen), 1% O2 and 5% CO2for 48 h, followed by 24 h of reoxygenation. Qualitative and quantitative histology and qRT-PCR were performed to discern phenotype, markers of hypoxia, programmed cell death and proliferation. ECOs self-organized into circular structures resembling biliary architecture containing cholangiocytes that expressed EpCAM, CK19, LGR5 and SOX-9. After hypoxia, ECOs showed increased expression of VEGF A (p < 0.0001), SLC2A1 (p < 0.0001) and ACSL4 (p < 0.0001) to indicate response to hypoxic damage and subsequent programmed cell death. Increase in cyclin D1 (p < 0.0001) after reoxygenation indicated proliferative activity in ECOs. Therefore, ECO structure and response to IRI are comparable to that found in-vivo, providing a suitable model to study IRI of the bile duct in-vitro.

Project description:BackgroundLiver metabolites are used to diagnose disease and examine drugs in clinical pharmacokinetics. Therefore, development of an in vitro assay system that reproduces liver metabolite recovery would provide important benefits to pharmaceutical research. However, liver models have proven challenging to develop because of the lack of an appropriate bile duct structure for the accumulation and transport of metabolites from the liver parenchyma. Currently available bile duct models, such as the bile duct cyst-embedded extracellular matrix (ECM), lack any morphological resemblance to the tubular morphology of the living bile duct. Moreover, these systems cannot overcome metabolite recovery issues because they are established in isolated culture systems. Here, we successfully established a non-continuous tubular bile duct structure model in an open-culture system, which closely resembled an in vivo structure. This system was utilized to effectively collect liver metabolites separately from liver parenchymal cells.ResultsTriple-cell co-culture of primary rat hepatoblasts, rat biliary epithelial cells, and mouse embryonic fibroblasts was grown to mimic the morphogenesis of the bile duct during liver development. Overlaying the cells with ECM containing a Matrigel and collagen type I gel mixture promoted the development of a tubular bile duct structure. In this culture system, the expression of specific markers and signaling molecules related to biliary epithelial cell differentiation was highly upregulated during the ductal formation process. This bile duct structure also enabled the separate accumulation of metabolite analogs from liver parenchymal cells.ConclusionsA morphogenesis-based culture system effectively establishes an advanced bile duct structure and improves the plasticity of liver models feasible for autologous in vitro metabolite-bile collection, which may enhance the performance of high-throughput liver models in cell-based assays.

Project description:Common bile duct injury is a severe complication. It is related to increased rates of morbidity and mortality. Early recognition and on-time diagnosis plus multidisciplinary management of this disease led by a hepatobiliary surgeon show fewer complications rate and best postoperative outcomes. However, no guidelines exist about the proper time of reconstruction. This study aims to describe the experience of a specialized Hepato-Pancreatic-Biliary (HPB) group and to analyze the outcomes regarding the time of bile duct injury (BDI) repair. A multicenter retrospective review of a prospective database was conducted. All the patients older than 18 years old that underwent common bile duct reconstruction between January 2014 and December 2021 were included. Analysis and description of preoperative characteristics and postoperative outcomes were performed. A reconstruction time-based group differentiation was made and analyzed. 44 patients underwent common bile duct reconstruction between January 2014 and December 2021. 56.82% of the patients were female. The mean age was 53.27 years ± 20.7 years. The most common injury was type E2 (29.55%). Hepaticojejunostomy was performed in 81.81% (of the patients. Delayed reconstruction (> 72 h) was performed in the majority of the cases (75.00%) due to delays in the referral centers or poor condition. No statistically significant difference regarding complications in early or delayed BDI reconstruction. The mortality rate was 2.7% (n = 1). 2-year follow-up bilioenteric stenosis was observed in 7 patients. Biloma showed a statistical relationship with complex bile duct injuries (p = 0.02). Bile duct injury is a severe and complex postoperative complication that increases morbidity and mortality rates in the short and long term in patients undergoing cholecystectomy. In our study, there were no statistical differences between the timing of bile duct reconstruction and the postoperative outcomes; we identified the presence of biloma as a statistically related factor associated with complex bile duct injury; however, further prospective or studies with an increased sample size are required to prove our results.
