Percutaneous management of bile duct strictures and injuries associated with laparoscopic cholecystectomy: a decade of experience

Long-term outcome of biliary reconstruction for bile duct injuries from laparoscopic cholecystectomies

BACKGROUND

Major bile duct injuries remain a potentially devastating complication after laparoscopic cholecystectomy. A retrospective review was conducted of patients who underwent a biliary-enteric reconstruction of a biliary injury to assess their long-term outcome.

METHODS

Retrospective review of bile duct injury database from January 1990 to December 2005.

RESULTS

A total of 144 patients were treated for bile duct injury, and 84 (58%) required a biliary-enteric reconstruction. Stratification by Bismuth-Strasberg injury level revealed E1 or E2 in 23, E3 in 33, E4 in 17, E5 in 1, and B+C in 10. Forty-four (52%) were operated within 7 days of laparoscopic cholecystectomy, the remainder operated at a median of 79 days after referral. Early or late mortality occurred in 3 (4%). At a mean follow-up of 67 months, 9 patients (11%) developed a biliary stricture presented at a median of 13 months after bile duct repair. Level of injury was very important in predicting a postoperative biliary stricture: E4 (35%) versus E3 (9%; P = .023), and E4 versus E1, E2 B+C (0%; P = .001). More strictures occurred in patients operated within 7 days of laparoscopic cholecystectomy (19%) versus delayed repair (8%; P = .053). Overall, 90% of patients are alive and nonstented; 5 patients have chronic liver disease (1 on the waiting list for liver transplant). Nonbiliary complications occurred in 15 patients; the total morbidity was 40%.

CONCLUSIONS

Bile duct injuries that require a biliary-enteric repair are commonly associated with long-term complications. Level of injury and likely timing of repair predict risk of postoperative stricture.

Survival in bile duct injury patients after laparoscopic cholecystectomy: a multidisciplinary approach of gastroenterologists, radiologists, and surgeons

BACKGROUND

Bile duct injury (BDI) after laparoscopic cholecystectomy (LC) has an enormous socioeconomic impact on patients. BDI has been associated with severe morbidity, impaired survival, and poor long-term quality of life. This study was performed to analyze the impact of a multidisciplinary approach in BDI patients on survival.

METHODS

A prospective cohort study was performed in a tertiary referral center to determine the effect of a multidisciplinary treatment on survival in 500 bile duct injury patients. Referral pattern and patient survival after bile duct injury are analyzed, and a survey was performed on the prevalence of medical litigation in bile duct injury patients.

RESULTS

The number of patients referred to the Amsterdam Medical Center increased to 0.3% of the total number of patients, yearly undergoing laparoscopic cholecystectomy in the Netherlands. The referral rate to the departments of gastroenterology (n = 329), surgery (n = 146), and radiology (n = 25) was, respectively, 66%, 29%, and 5%. After referral to the tertiary center, 150 patients (30%) were internally referred to a different department to optimize treatment. The 10-year survival rate in bile duct injury patients is not significantly worse compared with the age-matched general Dutch population (89% vs 88%, P = .7). Overall, 19% of the patients submitted a medical litigation claim against the initial surgeon or hospital. In total, 40% of these claims were resolved in the favor of the patients through settlement or verdict.

CONCLUSIONS

BDI is a severe complication in modern surgical practice. BDI is associated with major morbidity and high rates of litigation claims. The detrimental effect of BDI on survival can be prevented if gastroenterologists, radiologists, and surgeons work together in a multidisciplinary team.

Delayed-onset isolated injury of the right posterior segment duct after laparoscopic cholecystectomy: a report of hepatic segmental atrophy induction

Laparoscopic cholecystectomy resulted in various bile duct injuries. We present an unusual case of right posterior segment (RPS) duct injury detected 35 days after laparoscopic cholecystectomy. Imaging studies revealed that RPS duct was severed probably because of thermal damage from electrocautery. Initially, resection of RPS parenchyma had been planned, but atrophy induction of the involved hepatic parenchyma was attempted because the patient rejected the initial treatment plan. This treatment comprised embolization of RPS portal branch to inhibit bile production, induction of heavy adhesion at the bile leak site to ensure percutaneous transhepatic biliary drainage (PTBD) clamping, and clamping of PTBD tube to accelerate RPS atrophy. This procedure took 4 months before PTBD tube removal. The patient has showed no complications for 30 months to date. Although this atrophy induction approach cannot be regarded as a generally accepted treatment, we believe it can be considered a feasible option in rare circumstances such as this.

Endoscopic management of post-laparoscopic cholecystectomy biliary strictures. Long-term outcome in a multicenter study

OBJECTIVES

The aim of this retrospective study was to assess the long term results of long-lasting endoscopic stenting for benign biliary strictures related to laparoscopic cholecystectomy. Additional biological and morphological data were collected from these patients during follow-up.

METHODS

Patients undergoing ERCP for post-laparoscopic cholecystectomy biliary stricture in one of the three participating centers between 1990 and December 2001 were identified. Only patients with successful endoscopic stenting were subsequently included and analyzed. Follow-up data were obtained from referring centers, general practitioners and patients or relatives. Hepatic blood tests and abdominal ultrasound were proposed to all the patients who had not undergone further treatments after stent removal.

RESULTS

Eight-eight patients had undergone ERCP for benign biliary stricture related to laparoscopic cholecystectomy. Stenting failed in 19 patients. Balloon dilatation alone was used in four patients. Strictures were successfully stented in 65 patients. The mean number of stents inserted at the same time was 1.6. The mean duration of stenting was 14 months (range 1-120 months). Eighteen patients (28%) developed biliary or pancreatic symptoms during stenting. ERCP was considered satisfactory at the end of stenting (i.e. no remaining stricture or minor remaining change on ERCP) in 45 patients (69%). Twenty-two patients were lost to follow-up. Twenty-nine out of forty-three patients (67%) remained symptom-free with normal updated blood tests and abdominal ultrasound during a mean follow-up of 28 months (range 12-117 months) after stent removal. None of the patients with a normal ERCP at the end of stenting developed stricture recurrence during follow-up. Eleven patients were operated (8 with persistence of stricture, 2 for stricture recurrence up to 63 months after stent removal, 1 for pancreatitis).

CONCLUSION

Based on clinical, morphological and biological criteria, a long-term success was obtained in 70% of patients with post-laparoscopic cholecystectomy benign biliary strictures, after several months of endoscopic stenting.

Bile duct injury in the era of laparoscopic cholecystectomy

BACKGROUND

Laparoscopic cholecystectomy is the standard of care for symptomatic cholelithiasis, but it is associated with a higher incidence of bile duct injury than the open approach.

METHODS

A review was performed of the English language literature on the management of bile duct injury listed on Medline databases.

RESULTS AND CONCLUSION

There is consensus that careful dissection and correct interpretation of the anatomy avoids the complication of bile duct injury during cholecystectomy. Routine intraoperative cholangiography is associated with a lower incidence and early recognition of bile duct injury. Early detection and repair is associated with an improved outcome, and the minimum standard of care after the recognition of a bile duct injury is immediate referral to a surgeon experienced in bile duct injury repair. Surgery provides the mainstay of treatment, with proximal hepaticojejunostomy Roux en Y being the operation of choice; a selective role for endoscopic or radiological treatment exists. The outcome after bile duct injury remains poor, especially in relation to the initial expectation of the cholecystectomy. Patients are often committed to a decade of follow-up.

Lesão iatrogênica da via biliar principal em colecistectomia videolaparoscópica

OBJETIVO: Estudar a incidência, mortalidade e morbidez da lesão iatrogênica da via biliar em um Hospital Universitário onde os pacientes foram operados por vários cirurgiões em diferentes fases de treinamento (residentes e "staffs"). MÉTODO: Estudo retrospectivo de pacientes operados no Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro (HUCFF-UFRJ) no período entre janeiro de 1992 e dezembro de 2003. Foram pesquisadas as lesões da via biliar principal, o tempo de reconhecimento das mesmas (per ou pós operatória) e o tipo de reparo utilizado. RESULTADOS: Foram estudados 1589 pacientes com índice de lesão da via biliar de 0.25%, as quais ocorreram principalmente nos últimos anos do uso da técnica no hospital. CONCLUSÕES: A incidência de lesões da via biliar foi semelhante à da literatura e bastante próxima à da cirurgia convencional, e não esteve diretamente relacionada à curva de aprendizado do cirurgião.

Surgical management of bile duct injuries sustained during laparoscopic cholecystectomy: perioperative results in 200 patients

OBJECTIVE

A single institution retrospective analysis of 200 patients with major bile duct injuries was completed. Three patients died without surgery due to uncontrolled sepsis. One hundred seventy-five patients underwent surgical repair, with a 1.7% postoperative mortality and a complication rate of 42.9%.

SUMMARY BACKGROUND DATA

The widespread application of laparoscopic cholecystectomy (LC) has led to a rise in the incidence of major bile duct injuries (BDI). Despite the frequency of these injuries and their complex management, the published literature contains few substantial reports regarding the perioperative management of BDI.

METHODS

From January 1990 to April 2003, a prospective database of all patients with a BDI following LC was maintained. Patients' charts were retrospectively reviewed to analyze perioperative surgical management.

RESULTS

Over 13 years, 200 patients were treated for a major BDI following LC. Patient demographics were notable for 150 women (75%) with a mean age of 45.5 years (median 44 years). One hundred eighty-eight sustained their BDI at an outside hospital. The mean interval from the time of BDI to referral was 29.1 weeks (median 3 weeks). One hundred nine patients (58%) were referred within 1 month of their injury for acute complications including bile leak, biloma, or jaundice. Twenty-five patients did not undergo a surgical repair at our institution. Three patients (1.5%) died after delayed referral before an attempt at repair due to uncontrolled sepsis. Twenty-two patients, having intact biliary-enteric continuity, underwent successful balloon dilatation of an anastomotic stricture. A total of 175 patients underwent definitive biliary reconstruction, including 172 hepaticojejunostomies (98%) and 3 end-to-end repairs. There were 3 deaths in the postoperative period (1.7%). Seventy-five patients (42.9%) sustained at least 1 postoperative complication. The most common complications were wound infection (8%), cholangitis (5.7%), and intraabdominal abscess/biloma (2.9%). Minor biliary stent complications occurred in 5.7% of patients. Early postoperative cholangiography revealed an anastomotic leak in 4.6% of patients and extravasation at the liver dome-stent exit site in 10.3% of patients. Postoperative interventions included percutaneous abscess drainage in 9 patients (5.1%) and new percutaneous transhepatic cholangiography and stent placement in 4 patients (2.3%). No patient required reoperation in the postoperative period. The mean postoperative length of stay was 9.5 days (median 9 days). The timing of operation (early, intermediate, delayed), presenting symptoms, and history of prior repair did not affect the incidence of the most common perioperative complications or length of postoperative hospital stay.

CONCLUSIONS

This series represents the largest single institution experience reporting the perioperative management of BDI following LC. Although perioperative complications are frequent, nearly all can be managed nonoperatively. Early referral to a tertiary care center with experienced hepatobiliary surgeons and skilled interventional radiologists would appear to be necessary to assure optimal results.

[Bile duct injuries at laparoscopic cholecystectomy: early repair results]

STUDY AIM

To compare the early repair results in bile duct injuries at laparoscopic cholecystectomy to a later repair and so the early reconstruction by an end-to-end anastomosis to a Roux-en-Y bypass.

PATIENTS AND METHOD

From 1990 to 2003, twelve patients were treated for bile duct injury, not diagnosed at the time of cholecystectomy and had an early repair within 30 days after the cholecystectomy. They had either a duct to duct anastomosis or a Roux-en-Y bypass at the time of the reconstruction.

RESULTS

The level of the injury was Bismuth II (N=7), III (N=1), IV (N=2) and V (N=1) referral to Bismuth classification and one isolated right sectoral duct injury. Four patients had an duct to duct anastomosis and eight an hepaticojejunostomy at a median of 15.3 days after cholecystectomy. With one patient lost to follow up, the overall success rate in this series was 81.8% after reconstruction with a mean 40 months follow up. The reconstruction by an end to end anastomosis was successful in 100% of patients (with a mean 31.2 months follow up) and in 71.4% of patients after a Roux-en-Y biliary reconstruction (with a mean 45 months follow up).

CONCLUSION

Good results may be performed, by an early repair in bile duct injuries at laparoscopic cholecystectomy, either by an duct to duct anastomosis or a Roux-en-Y bypass.

Laparoscopic Bile Duct Injuries: Management at a Tertiary Liver Center

Bile duct injury is a rare but morbid complication of laparoscopic cholecystectomy (LC). This study was undertaken to evaluate the management of 20 patients with bile duct injuries during LC who were referred to a tertiary center with expertise in hepatobiliary surgery and liver transplantation. Sixteen (80%) were female. Mean age was 44 (range 13–70) years. Half of the injuries were distal (Bismuth I), and nearly half were diagnosed at LC. Reoperative repair was attempted in 30 per cent. Mean interval between injury and operation was 6.55 months (range 0 to 36 months). Eighteen patients underwent Roux-en-Y hepaticojejunostomy (HJ). Of the two patients who did not undergo HJ (both Bismuth I), one was treated with transhepatic cholangiography only, and one died of multiorgan failure. There were four minor complications and one late reoperation for stricture. We conclude that bile duct injury after LC is successfully managed in a tertiary center by a hepatobiliary-liver transplant team. Principles of management include anatomic definition of injury, control of sepsis, staged approach involving interventional radiology, and operative techniques refined in liver transplantation including magnification, fine sutures, selective use of internal stent, and liver biopsy.
