Surgical management for bile duct injury

Analysis of risk factors for bile duct injury in laparoscopic cholecystectomy in China: A systematic review and meta-analysis

BACKGROUND

To explore the risk factors of bile duct injury in laparoscopic cholecystectomy (LC) in China through meta-analysis.

METHODS

The study commenced with a search and selection of case-control studies on the risk factors for bile duct injury in LC in China using the following databases: PubMed, EMBASE, ScienceNet.cn, CNKI, Wanfang Data, and VIP. Data were extracted from the collected documents independently by 2 researchers, following which a meta-analysis of these data was performed using Revman 5.3.

RESULTS

The compilation of all data from a total of 19 case-control studies revealed that among 41,044 patients, 458 patients experienced bile duct injury in LC, accounting for the incidence rate of 1.12% for bile duct injury. The revealed risk factors for bile duct injury were age (≥40 years) (odds ratio [OR] = 6.23, 95% CI [95% confidence interval]: 3.42-11.33, P < .001), abnormal preoperative liver function (OR = 2.01, 95% CI: 1.50-2.70, P < .001), acute and subacute inflammation of gallbladder (OR = 8.35, 95% CI: 5.32-13.10, P < .001; OR = 4.26, 95% CI: 2.73-6.65, P < .001), thickening of gallbladder wall (≥4 mm) (OR = 3.18, 95% CI: 2.34-4.34, P < .001), cholecystolithiasis complicated with effusion (OR = 3.05, 95% CI: 1.39-6.71, P = .006), and the anatomic variations of the gallbladder triangle (OR = 11.82, 95% CI: 6.32-22.09, P < .001). However, the factors of gender and overweight (body mass index ≥ 25 kg/m2) were not significantly correlated with bile duct injury in LC.

CONCLUSIONS

In the present study, age (≥40 years), abnormal preoperative liver function, gallbladder wall thickening, acute and subacute inflammation of the gallbladder, cholecystolithiasis complicated with effusion, and anatomic variations of the gallbladder triangle were found to be closely associated with bile duct injury in LC.

Total Hilar Exposure Maneuver for Repair of Complex Bile Duct Injury

The reconstruction of high-level bile duct injury is challenging because exposure of the hilar area is limited and sometimes inaccessible by the Hepp-Couinaud approach. We describe a maneuver for total hilar exposure to perform complex bile duct injury reconstruction. After adhesions surrounding the liver are divided, intraoperative ultrasonography is used to delineate the hilar and intrahepatic biliary anatomy. Surgical exposure of the biliary system is achieved by our maneuver, which consists of four steps: (1) identification of landmark structures, such as the base of the umbilical fissure, the inferior edge of segment 4b, the cystic-hilar plate junction, and the right anterior portal pedicle; (2) lowering of the hilar plate; (3) hepatotomy along the right anterior pedicle; and (4) connection of the hepatotomy to the base of segment 4b. This maneuver allows the liver to be flipped upward, which facilitates clear exposure of the hilar duct and preserves the liver parenchyma. The anterior parts of the right and left hepatic duct are then opened, a wide-hepaticojejunostomy anastomosis is achieved for biliary reconstruction, and a jejunal subcutaneous limb is created. We used this maneuver for treating complex bile duct injury in six cases; none of the patients has died, and two had Clavien-Dindo grade III complications, including surgical site infection and intra-abdominal collection. The total hilar exposure maneuver is thus feasible and safe. It provides excellent exposure of both hepatic ducts and is a good surgical alternative to the Hepp-Couinaud approach in cases of high-level injury.

MRI evaluation of bile duct injuries and other post-cholecystectomy complications

Laparoscopic cholecystectomy is one of the most common procedures performed each year and can be associated with various post-operative complications. Imaging is integral to diagnosis and management of patients with suspected cholecystectomy complications, and a thorough understanding of normal and abnormal biliary anatomy, risk factors for biliary injury, and the spectrum of adverse events is crucial for interpretation of imaging studies. Magnetic resonance cholangiography (MRC) enhanced with hepatobiliary contrast agent is useful in delineating biliary anatomy and pathology following cholecystectomy. In this article, we provide a protocol for contrast-enhanced MR imaging of the biliary tree. We also review the classification and imaging manifestations of post-cholecystectomy bile duct injuries in addition to other complications such as bilomas, retained/dropped gallstones, and vascular injuries.

Use of bacterial cellulose film for repair of bile duct injury in pigs

BACKGROUND/OBJECTIVE

The aim was to evaluate the use of bacterial cellulose film and bile duct autograft in repairing critical common bile duct injury in pigs.

METHODS

A prospective experimental analytical study was carried out on 20 Sus Domesticus, Piau suidae swine, divided into a control group (n = 10) and an experimental group (n = 10) divided into two subgroups: bacterial cellulose film E1 and bacterial cellulose film E2 to which bacterial cellulose film was randomly allocated. The control group underwent two complete critical common bile duct sections 10 mm apart, while the experimental group with a single critical common bile duct defect underwent a 10 mm section of the longitudinal shaft with edge resection. The defects in the control group were treated with end-to-end conventional anastomosis using polyglycolic 6-0 surgical thread and the experimental group with bacterial cellulose film by continuous suture using the same material. The animals were clinically evaluated throughout the experiment on days D150 (bacterial cellulose film E1), D225 (control group), and D330 (bacterial cellulose film E2) and by intraoperative ultrasound examination related to histopathological and biochemical findings.

RESULTS

The intraoperative ultrasonography detected the changes resulting from the common bile duct anastomosis in the control group that produced a considerable incidence of ductal narrowing and obstruction to the biliary flow. In the bacterial cellulose film E2 group, there was an increase in inflammation intensity, granulomatous reaction, fibrosis, and vessels density, without producing bile duct dilation in the ultrasonography assessment. Biochemical analysis of liver enzymes yielded results in the normal range confirming preservation of liver function at the different post-surgery time points.

CONCLUSION

Bacterial cellulose film, when used as a graft for bile duct repair, proved to be a biocompatible material that produced a complete healing process and biliary flow continuity.

Bile Duct Injury Repairs after Laparoscopic Cholecystectomy: A Five-Year Experience in a Highly Specialized Community Hospital

Bile duct injury represents a complication after laparoscopic cholecystectomy, impairing quality of life and resulting in subsequent litigations. A five-year experience of bile duct injury repairs in 52 patients at a community hospital was reviewed. Twenty-nine were female, and the median age was 51 years (range, 20–83 years). Strasberg classification identified injuries as Type A (23), B (1), C (1), D (5), E1 (5), E2 (6), E3 (4), E4 (6), and E5 (1). Resolution of the bile duct injury and clinical improvement represent main postoperative outcome measures in our study. The referral time for treatment was within 4 to 14 days of the injury. Type A injury was treated with endobiliary stent placement. The remaining patients required T-tube placement (5), hepaticojejunostomy (20), and primary anastomosis (4). Two patients experienced bile leak after hepaticojejunostomy and were treated and resolved with percutaneous transhepatic drainage. At a median follow-up of 36 months, two patients (Class E4) required percutaneous balloon dilation and endobiliary stent placement for anastomotic stricture. The success of biliary reconstruction after complicated laparoscopic cholecystectomy can be achieved by experienced biliary surgeons with a team approach in a community hospital setting.

Surgical management of laparoscopic cholecystectomy (LC) related major bile duct injuries; predictors of short-and long-term outcomes in a tertiary Egyptian center- a retrospective cohort study

Objectives

Laparoscopic cholecystectomy - associated bile duct injury is a clinical problem with bad outcome. The study aimed to analyze the outcome of surgical management of these injuries.

Patients and methods

We retrospectively analyzed 69 patients underwent surgical management of laparoscopic cholecystectomy related major bile duct injuries in the period from the beginning of 2013 to the beginning of 2018.

Results

Regarding injury type; the Leaking, Obstructing, leaking + obstructing, leaking + vascular, and obstructing + vascular injuries were 43.5%, 27.5%, 18.8%, 2.9%, and 7.2% respectively. However, the Strasberg classification of injury was as follow E1 = 25, E2 = 32, E3 = 8, and E4 = 4. The definitive procedures were as follow: end to end biliary anastomosis with stenting, hepaticojejunostomy (HJ) with or without stenting, and RT hepatectomy plus biliary reconstruction with stenting in 4.3%, 87%, and 8.7% of patients respectively. According to the time of definitive procedure from injury; the immediate (before 72 h), intermediate (between 72 h and 1.5months), and late (after1.5 months) management were 13%, 14.5%, and 72.5% respectively. The hospital and/or 1month (early) morbidity after definitive treatment was 21.7%, while, the late biliary morbidity was 17.4% and the overall mortality was 2.9%, on the other hand, the late biliary morbidity-free survival was 79.7%. On univariate analysis, the following factors were significant predictors of early morbidity; Sepsis at referral, higher Strasberg grade, associated vascular injury, right hepatectomy with biliary reconstruction as a definitive procedure, intra-operative bleeding with blood transfusion, liver cirrhosis, and longer operative times and hospital stays. However, the following factors were significantly associated with late biliary morbidity: Sepsis at referral, end to end anastomosis with stenting, reconstruction without stenting, liver cirrhosis, operative bleeding, and early morbidity.

Conclusion

Sepsis at referral, liver cirrhosis, and operative bleeding were significantly associated with both early and late morbidities after definitive management of laparoscopic cholecystectomy related major bile duct injuries, so it is crucial to avoid these catastrophes when doing those major procedures.
