Long-Term Impact of Iatrogenic Bile Duct Injury

Endoscopic internal drainage of complex bilomas and biliary leaks by transmural or transpapillary/transfistulary access

BACKGROUND AND AIMS

Bilomas most frequently result from postoperative bile leaks. The endoscopic conventional treatment is sphincterotomy ± stent placement. In complex cases, such as altered anatomy or failure of conventional treatment, transpapillary/transfistulary (TP/TF) drainage or EUS-guided transmural drainage (EUS-TD) may obviate additional biliary surgery. This study reports our experience with treating biloma secondary to refractory biliary leak with TP/TF drainage or EUS-TD and evaluates the safety and outcomes associated with this approach.

METHODS

This observational study focused on consecutive patients managed for biliary leakage (diagnosis based on imaging and/or bile outflow from a surgical drain) at a tertiary care hospital (2007-2017). TP/TF drainage was performed by double-pigtail stent(s) placement to drain the biloma through the leak during ERCP. For EUS-TD, plastic stent(s) were placed under EUS control. Primary outcomes were a composite of clinical success (patient free of sepsis after percutaneous drain removal and, in patients with benign disease, removal of all endoscopically placed stents, without need for reintervention) and biloma regression (<3 cm) at last follow-up.

RESULTS

Thirty patients (men, 57%; median age, 55 years) were included. Most biliary leaks resulted from cholecystectomy (27%) and hepatectomy (50%). Initial EUS-TD and TP/TF drainage were performed in 14 (47%) and 16 (53%) patients, respectively. At last follow-up (median, 33.2 months), clinical success and primary outcome were achieved in 70.4% of patients (EUS-TD, 75%; TP/TF, 67%). Additional surgery was necessary in 1 patient. Rate of serious adverse events was 23% (7/30), of which 13% (4/30) were procedure related. There were 4 deaths during the course of treatment, 2 of which were related to endoscopic interventions (hemorrhage and fibrillation).

CONCLUSIONS

TP/TF drainage or EUS-TD is technically feasible with high clinical success and may avoid the need for additional surgery in complex cases or in patients with altered anatomy.

Liver transplantation for the treatment of iatrogenic bile duct injury

ABSTRACT Objective: to assess the outcomes of our patients who were subjected to LT for iatrogenic bile duct injury. Methods: all patients who underwent LT for treatment of complications of biliary duct injury were included in the study. Medical records and study protocols of these patients were retrospectively analyzed to determine demographic and clinical characteristics, treatment, and outcome of the patients. Results: of a total of 846 liver transplants performed, 12 (1.4%) were due to iatrogenic bile duct injury: 10 (83.3%) occurred during cholecystectomy, 1 (8.3%) following chemoembolization, and 1 (8.3%) during laparotomy to control abdominal bleeding. Cholecystectomy was performed by open access in 8 patients and by laparoscopic access in two . There were 8 female (66.7%) and 4 male (33.3%) with a mean age of 50.6 ± 13.1 years (range 23 to 70 years). All transplants were performed with livers from cadaveric donors. The mean operative time was 558.2 ± 105.2 minutes (range, 400-782 minutes). Biliary reconstruction was performed with Roux-en-Y hepaticojejunostomy in 11 patients and choledochocholedochostomy in one. Seven patients died (58.3%) and five (41.7%) were alive during a mean followed up of 100 months (range 18 to 118 months). Conclusion: liver transplantation in patients with iatrogenic bile duct injury is a complex procedure with elevated morbimortality.

Progress and Current Limitations of Materials for Artificial Bile Duct Engineering

Bile duct injury (BDI) and bile tract diseases are regarded as prominent challenges in hepatobiliary surgery due to the risk of severe complications. Hepatobiliary, pancreatic, and gastrointestinal surgery can inadvertently cause iatrogenic BDI. The commonly utilized clinical treatment of BDI is biliary-enteric anastomosis. However, removal of the Oddi sphincter, which serves as a valve control over the unidirectional flow of bile to the intestine, can result in complications such as reflux cholangitis, restenosis of the bile duct, and cholangiocarcinoma. Tissue engineering and biomaterials offer alternative approaches for BDI treatment. Reconstruction of mechanically functional and biomimetic structures to replace bile ducts aims to promote the ingrowth of bile duct cells and realize tissue regeneration of bile ducts. Current research on artificial bile ducts has remained within preclinical animal model experiments. As more research shows artificial bile duct replacements achieving effective mechanical and functional prevention of biliary peritonitis caused by bile leakage or obstructive jaundice after bile duct reconstruction, clinical translation of tissue-engineered bile ducts has become a theoretical possibility. This literature review provides a comprehensive collection of published works in relation to three tissue engineering approaches for biomimetic bile duct construction: mechanical support from scaffold materials, cell seeding methods, and the incorporation of biologically active factors to identify the advancements and current limitations of materials and methods for the development of effective artificial bile ducts that promote tissue regeneration.

Achieving the critical view of safety in the difficult laparoscopic cholecystectomy: a prospective study of predictors of failure

BACKGROUND

Bile duct injury rates for laparoscopic cholecystectomy (LC) remain higher than during open cholecystectomy. The "culture of safety" concept is based on demonstrating the critical view of safety (CVS) and/or correctly interpreting intraoperative cholangiography (IOC). However, the CVS may not always be achievable due to difficult anatomy or pathology. Safety may be enhanced if surgeons assess difficulties objectively, recognise instances where a CVS is unachievable and be familiar with recovery strategies.

AIMS AND METHODS

A prospective study was conducted to evaluate the achievability of the CVS during all consecutive LC performed over four years. The primary aim was to study the association between the inability to obtain the CVS and an objective measure of operative difficulty. The secondary aim was to identify preoperative and operative predictors indicating the use of alternate strategies to complete the operation safely.

RESULTS

The study included 1060 consecutive LC. The median age was 53 years, male to female ratio was 1:2.1 and 54.9% were emergency admissions. CVS was obtained in 84.2%, the majority being difficulty grade I or II (70.7%). Displaying the CVS failed in 167 LC (15.8%): including 55.6% of all difficulty grade IV LC and 92.3% of difficulty grade V. There were no biliary injuries or conversions.

CONCLUSION

All three components of the critical view of safety could not be demonstrated in one out of 6 consecutive laparoscopic cholecystectomies. Preoperative factors and operative difficulty grading can predict cases where the CVS may not be achievable. Adapting instrument selection and alternate dissection strategies would then need to be considered.

Laparoscopic cholecystectomy in a swine model using a novel near-infrared fluorescent IV dye (BL-760)

BACKGROUND AND OBJECTIVES

Bile duct injury during laparoscopic cholecystectomy has an incidence rate of 1%-2% and commonly appears under conditions of severe inflammation, adhesion, or unexpected anatomical variations. Despite the difficulties and rising concerns of identifying bile duct during surgeries, surgeons do not have a specific modality to identify bile duct except intraoperative cholangiography. While no biliary-specific fluorescent dye exists for clinical use, our team has previously described the development of a preclinical biliary-specific dye, BL-760. Here, we present our study of laparoscopic cholecystectomy using the fluorescent dye in a swine model.

STUDY DESIGN/MATERIALS AND METHODS

With an approval from Institutional Animal Care and Use Committee, two 20-25 kg swine underwent laparoscopic abdominal surgery using a Food and Drug Administration-cleared fluorescent laparoscopic system. Images of the liver and gallbladder were taken both before and after intravenous injection of the novel fluorescent dye. The dye was dosed at 60 μg/kg and injected via the ear vein. The amount of time taken to visualize fluorescence in the biliary tract was measured. Fluorescent signal was observed after injection, and target-to-background ratio (TBR) of the biliary tract to surrounding cystic artery and liver parenchyma was measured.

RESULTS

Biliary tract visualization under fluorescent laparoscopy was achieved within 5 min after the dye injection without any adverse effects. Cystic duct and extrahepatic duct were clearly visualized and identified with TBR values of 2.19 and 2.32, respectively, whereas no fluorescent signal was detected in liver. Cystic duct and artery were successfully ligated by an endoscopic clip applier with the visual assistance of highlighted biliary tract images. Laparoscopic cholecystectomy was completed within 30 min in each case without any complications.

CONCLUSIONS

BL-760 is a novel preclinical fluorescent dye useful for intraoperative identification and visualization of biliary tract. Such fluorescent dye that is exclusively metabolized by liver and rapidly excreted into biliary tract would be beneficial for all types of hepato-biliary surgeries. With the validation of additional preclinical data, this novel dye has potential to be a valuable tool to prevent any iatrogenic biliary injuries and/or bile leaks during laparoscopic abdominal and liver surgeries.

Comparison of intraoperative endoscopic retrograde cholangiopancreatography and laparoscopic common bile duct exploration combined with laparoscopic cholecystectomy for treating gallstones and common bile duct stones: a systematic review and meta-analysis

BACKGROUND

This study aimed to compare the efficacy and safety of laparoscopic cholecystectomy combined with intraoperative endoscopic retrograde cholangiopancreatography (LC-IntraERCP) and laparoscopic cholecystectomy combined with laparoscopic common bile duct exploration (LC-LCBDE) to determine which one-stage therapeutic strategy provides better outcomes for patients with gallstones and common bile duct stones.

METHODS

Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched to identify eligible articles from the database inception to September 2020. The revised Cochrane risk of bias tools for randomized trials (RoB-2) and non-randomized interventions (ROBINS-I) was used to assess the quality of the included studies. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. The primary outcomes consisted of surgical success, retained stones, and overall postoperative complications, while secondary outcomes included postoperative bleeding, postoperative pancreatitis, postoperative bile leakage, conversion to laparotomy, and operative time.

RESULTS

Eight studies (four RCTs and four Non-RCTs with high quality) with 2948 patients were included. No significant difference was seen between the two groups regarding surgical success, overall postoperative complications, conversion to laparotomy, and operative time. The meta-analysis demonstrated that in the LC-IntraERCP group, the rate of retained stones (OR 0.51, 95% CI 0.28-0.91) and postoperative bile leakage were lower (OR 0.25, 95% CI 0.09-0.69), while in the LC-LCBDE group, postoperative bleeding (OR 5.24, 95% CI 1.65-16.65) and postoperative pancreatitis (OR 4.80, 95% CI 2.35-9.78) decreased.

CONCLUSIONS

LC-IntraERCP and LC-LCBDE exhibited similar efficacies when surgical success rate, overall postoperative complications, conversion to laparotomy, and operative time were compared. However, LC-IntraERCP is probably to be more effective in terms of lowering the rate of retained stones.

Percutaneous transhepatic cholangiography in the era of magnetic resonance cholangiopancreatography: A prospective comparative analysis in preoperative evaluation of benign biliary stricture

Background and Aim

Accurate anatomical delineation is the key before definitive repair for benign biliary stricture (BBS). The role of percutaneous transhepatic cholangiography (PTC) as a road map is less studied in the era of magnetic resonance cholangiopancreatography (MRCP).

Methods

A prospective observational study, performed between July 2012 and December 2013. All patients of post‐cholecystectomy BBS were evaluated with MRCP and PTC prior to definitive repair. Findings of MRCP and PTC were compared with intraoperative details.

Results

Thirty patients with BBS were included in the study. MRCP was performed in all but PTC was amenable in 28 of 30 (93.3%) patients. PTC was comparable to MRCP in diagnosing stricture type (96.4% vs 89.3%), intrahepatic stones (75% vs 75%), and biliary anomalies (95.6% vs 100%). Additionally, PTC revealed internal biliary fistula in 4 (85.7% vs 61.4%; P value 0.04). PTC‐related minor complications were noted in 2 (7.1%) patients.

Conclusion

PTC is comparable to MRCP in diagnosing the stricture type, intrahepatic biliary stones, and biliary anomalies. Though comparable to MRCP, the authors could not reveal any additional information that could change the course of management in BBS.

2020 WSES guidelines for the detection and management of bile duct injury during cholecystectomy

Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.

Novel Use of Intraoperative Fluoroscopy in an Era of ICG for Complex Laparoscopic Cholecystectomy

Background  Laparoscopic cholecystectomy (LC) is increasingly being used as a first-line treatment for acute cholecystitis. Bile duct injury (BDI) remains the most feared complication of the minimally invasive approach specially in cases with an inflamed calots triangle. While use of indocyanine dye (ICG) to delineate biliary anatomy serves to reduce BDI, the high cost of the technology prohibits its use in the developing world. We propose a novel use of common bile duct (CBD) stenting preoperatively in cases of cholecystitis secondary to choledocholithiasis as a means of identification and safeguarding the CBD.

Methods  A retrospective review was conducted on 22 patients of Grade 2 or Grade 3 cholecystitis who underwent an early LC at our institution. All patients were stented preoperatively and the stent was used for a much-needed tactile feedback during dissection. A c-arm with intraoperative fluoroscopy was used to identify the CBD prior to clipping of the cystic duct.

Results  The gall bladder was gangrenous in all the cases while two cases had evidence of end organ damage. This innovative use of CBD stenting allowed us to correctly delineate biliary anatomy in all of the cases and we report no instances of BDI despite a severely inflamed local environment.

Conclusion  This technique can become a standard of care in all teaching institutions in developing countries further enhancing the safety of cholecystectomy in gangrenous cholecystitis with a distorted biliary anatomy.

Bile Duct Injury During Cholecystectomy: Necessity to Learn How to Do and Interpret Intraoperative Cholangiography

Introduction: Biliary duct injury (BDI) is a serious complication during cholecystectomy. Perioperative cholangiography (POC) has recently been generating interest in order to prevent BDI. However, the current literature (including randomized controlled trials) cannot conclude whether POC is protective or not against the risk of BDI. The aim of our study was to investigate whether POC could demonstrate earlier BDI and which criteria are required to make that diagnosis.

Methods: We performed a retrospective study between 2005 and 2018 in our French tertiary referral center, which included all patients who had presented following BDI during cholecystectomy.

Results: Twenty-two patients were included. Nine patients had POC, whereas 13 did not. When executed, POC was interpreted as normal for three patients and abnormal for six. In this latter group, only two cases had a BDI diagnosed intraoperatively. In other cases, the interpretation was not adequate.

Conclusion: BDIs are rare but may reduce patients' quality of life. Our study highlights the surgeon's responsibility to learn how to perform and interpret POC in order to diagnose and manage BDIs and potentially avoid catastrophic consequences.

Impact of referral pattern and timing of repair on surgical outcome after reconstruction of post-cholecystectomy bile duct injury: A multicenter study

BACKGROUND

Bile duct injury (BDI) after cholecystectomy remains a significant surgical challenge. No guideline exists to guide the timing of repair, while few studies compare early versus late repair BDI. This study aimed to analyze the outcomes in patients undergoing immediate, intermediate, and delayed repair of BDI.

METHODS

We retrospectively analyzed 412 patients with BDI from March 2015 to January 2020. The patients were divided into three groups based on the time of BDI reconstruction. Group 1 underwent an immediate reconstruction (within the first 72 hours post-cholecystectomy, n = 156); group 2 underwent an intermediate reconstruction (from 4 days to 6 weeks post-cholecystectomy, n = 75), and group 3 underwent delayed reconstruction (after 6 weeks post-cholecystectomy, n = 181).

RESULTS

Patients in group 2 had significantly more early complications including anastomotic leakage and intra-abdominal collection and late complications including anastomotic stricture and secondary liver cirrhosis compared with groups 1 and 3. Favorable outcome was observed in 111 (71.2%) patients in group 1, 31 (41.3%) patients in group 2, and 157 (86.7%) patients in group 3 (P = 0.0001). Multivariate analysis identified that complete ligation of the bile duct, level E1 BDI and the use of external stent were independent factors of favorable outcome in group 1, the use of external stent was an independent factor of favorable outcome in group 2, and level E4 BDI was an independent factor of unfavorable outcome in group 3. Transected BDI and level E4 BDI were independent factors of unfavorable outcome.

CONCLUSIONS

Favorable outcomes were more frequently observed in the immediate and delayed reconstruction of post-cholecystectomy BDI. Complete ligation of the bile duct, level E1 BDI and the use of external stent were independent factors of a favorable outcome.

The “critical view of safety (CVS)” cannot be applied—What to do? Strategies to avoid bile duct injuries

Laparoscopic cholecystectomy has become the standard procedure worldwide since the early 1990s for those patients whose gallbladder has to be removed as part of their underlying disease (NIH Consensus Statement 1992). The most common complication is iatrogenic bile duct injury, which has not improved significantly since the introduction of open laparoscopic cholecystectomy as compared with open cholecystectomy. The intraoperative injuries are mostly the result of a misinterpretation of anatomical structures due to severe inflammation or topographical variations. In order to minimize this risk, a number of improved operative techniques and behavioral measures have been formulated. Here, we present methodological and operative possibilities as well as techniques that in unclear situations can help to minimize the risk of intraoperative injuries of the biliary tract and the accompanying vascular system.

Recommendation for Photographic Documentation of Safe Laparoscopic Cholecystectomy

Background

Bile duct injury and vasculobiliary injury are possible complications during laparoscopic cholecystectomy which can lead to increased morbidity, mortality, costs of hospitalization and litigation. Proper documentation of the critical view of safety and safe plane of dissection may play a crucial role for archivization, teaching and medicolegal purposes.

Methods

The study group consisted of 100 patients with symptomatic cholecystolithiasis qualified for laparoscopic cholecystectomy. The critical view of safety was documented on two photographs and safe plain of dissection obtained with laparoscopic ultrasound was documented on one photograph as well as the whole procedure was recorded. The photographs were printed in the operating theatre and videos were stored on an external hard drive.

Results

The mean time to obtain and analyse photographs was significantly shorter than video, and the size of the stored data was significantly smaller for photographs than videos. The cost of one documentation procedure was significantly lower for video than photographs. Critical view of safety was obtained in 91 patients, and laparoscopic ultrasound was successful in 99 patients. The conversion rate was 2%, and fundus-first cholecystectomies were performed in 6% of patients. We did not observe any biliary and vascular complications.

Conclusions

Photographic documentation of the critical view of safety and safe plane of dissection should be an inherent part of laparoscopic cholecystectomy. Our proposal of documentation prepared in the operating theatre and stored in the patient’s documentation is an example of an easy, fast and cheap method of data archivization.

Optimal timing for surgical reconstruction of bile duct injury: meta-analysis

Background

Major bile duct injury (BDI) after cholecystectomy generally requires surgical reconstruction by means of hepaticojejunostomy. However, there is controversy regarding the optimal timing of surgical reconstruction.

Methods

A systematic review was performed by searching PubMed, Embase and Cochrane databases for studies published between 1990 and 2018 reporting on the timing of hepaticojejunostomy for BDI (PROSPERO registration CRD42018106611). The main outcomes were postoperative morbidity, postoperative mortality and anastomotic stricture. When individual patient data were available, time intervals of these studies were attuned to render these comparable with other studies. Data for comparable time intervals were pooled using a random‐effects model. In addition, data for all included studies were pooled using a generalized linear model.

Results

Some 21 studies were included, representing 2484 patients. In these studies, 15 different time intervals were used. Eight studies used the time intervals of less than 14 days (early), 14 days to 6 weeks (intermediate) and more than 6 weeks (delayed). Meta‐analysis revealed a higher risk of postoperative morbidity in the intermediate interval (early versus intermediate: risk ratio (RR) 0·73, 95 per cent c.i. 0·54 to 0·98; intermediate versus delayed: RR 1·50, 1·16 to 1·93). Stricture rate was lowest in the delayed interval group (intermediate versus delayed: RR 1·53, 1·07 to 2·20). Postoperative mortality did not differ within time intervals. The additional analysis demonstrated increased odds of postoperative morbidity for reconstruction between 2 and 6 weeks, and decreased odds of anastomotic stricture for delayed reconstruction.

Conclusion

This meta‐analysis found that surgical reconstruction of BDI between 2 and 6 weeks should be avoided as this was associated with higher risk of postoperative morbidity and hepaticojejunostomy stricture.

Outcomes and quality of life after major bile duct injury in long-term follow-up

Introduction

Recently new standards for reporting outcomes of bile duct injury (BDI) have been proposed. It is unclear how these treatment outcomes are reflected in quality of life (QOL). The aim of this study was to report outcomes and QOL after repair of major BDI and compare repairs by hepatobiliary surgeon to repairs by non-hepatobiliary surgeons.

Methods

This was a retrospective study of patients treated for major (Strasberg E-type) BDI after cholecystectomy at a tertiary hepatobiliary center. Outcomes were assessed using Cho-Strasberg proposed standards. QOL was assessed using Short Form Health Survey (SF-36) and the gastrointestinal QOL-index (GIQLI). Patients undergoing uneventful cholecystectomy matched by age, urgency, and duration of follow-up were used as controls.

Results

Fifty-two patients with major BDI treated between 2000 and 2016 were included (42% male, median age 53 years). Thirty-seven (71%) patients attained primary patency (29 (83%) if primarily operated by a hepatobiliary surgeon). Actuarial primary patency rate (grade A result) at 1, 3, and 5 years was 58%, 56%, and 53% in the whole cohort, and 83%, 80%, and 80% in patients primary treated by a hepatobiliary surgeon, respectively. At 3-year follow-up 6 (11.5%) patients obtained grade B, 10 (19.2%) grade C, and 7 (13.5%) grade D result. QOL was similar in patients with BDI and controls (median SF-36 physical component 51.7 and 53.6, p = 1.0, mental component 53.3 and 53.4, p = 1.0, GIQLI 109.0 and 123.0, p = 0.174, respectively) at median 90 (IQR 70–116) months from cholecystectomy. QOL was similar regardless of outcome grade.

Conclusion

First attempt to repair a severe BDI should be undertaken by a hepatobiliary surgeon. However, long-term QOL is not affected even by severe BDI, and QOL is not associated with the grade of the outcome.

Challenging biliary strictures: pathophysiological features, differential diagnosis, diagnostic algorithms, and new clinically relevant biomarkers - part 1

It is frequently challenging to make the correct diagnosis in patients with biliary strictures. This is particularly important as errors may have disastrous consequences. Benign-appearing strictures treated with stents may later be revealed to be malignant and unnecessary surgery for benign strictures carries a high morbidity rate. In the first part of the review, the essential information that clinicians need to know about diseases responsible for biliary strictures is presented, with a focus on the most recent data. Then, the characteristics and pitfalls of the methods used to make the diagnosis are summarized. These include serum biomarkers, imaging studies, and endoscopic modalities. As tissue diagnosis is the only 100% specific tool, it is described in detail, including techniques for tissue acquisition and their yields, how to prepare samples, and what to expect from the pathologist. Tricks to increase diagnostic yields are described. Clues are then presented for the differential diagnosis between primary and secondary sclerosing cholangitis, IgG4-related sclerosing cholangitis, cholangiocarcinoma, pancreatic cancer, autoimmune pancreatitis, and less frequent diseases. Finally, algorithms that will help to achieve the correct diagnosis are proposed.

[Management of bile duct injuries]

Bile duct injuries can occur after abdominal trauma, postoperatively after cholecystectomy, liver resection or liver transplantation and also as a complication of endoscopic retrograde cholangiopancreatography (ERCP). The clinical appearance of bile duct injuries is highly variable and depends primarily on the underlying cause. In addition to the high perioperative morbidity, following successful initial complication management, bile duct injuries can lead to significant long-term complications. The treatment requires close interdisciplinary cooperation between surgery, interventional gastroenterology and interventional radiology. The treatment of bile duct injuries depends primarily on the time of diagnosis (intraoperative/postoperative) as well as the extent of the injury and is discussed in this review.
