The outcome of endoscopic treatment in bile duct injury after cholecystectomy]

BACKGROUND/AIMS: Bile duct injury is the most serious complication of cholecystectomy. The aim of this study was to evaluate the outcome of endoscopic treatment in bile duct injury after cholecystectomy. METHODS: We reviewed the results of endoscopic treatments in the patients diagnosed as bile duct injury after cholecystectomy on cholangiographic examinations, retrospectively. Endoscopic treatment included insertion of nasobiliary drainage catheter or plastic stent after endoscopic sphicterotomy. RESULTS: A total of twenty-two patients (9 male, 13 female; median age of 59 years) with bile duct injury were included. Endoscopic treatment was successfully performed in 12 of 13 patients with bile leak only. In patients with both bile leak and stricture, endoscopic treatment was successful in 2 of 3 patients. In 6 patients with complete obstruction of bile duct, endoscopic treatment failed and surgical approach was needed. In our series, transpapillary endoscopic treatment was not successful when proximal bile duct above the injured site was not visualized by endoscopic retrograde cholangiopancreatography (ERCP) and surgery was performed in all cases. Overall success rate of endoscopic treatment in 22 patients with bile duct injury was 64% (14/22). There was no complication associated with endoscopic treatment. CONCLUSIONS: ERCP is useful for the treatment of bile leakage after cholecystectomy and can be used for the treatment prior to surgery. Surgical intervention is needed in case of endoscopic treatment failure.     

ERCP对肝移植术后胆漏诊治作用的前瞻性临床观察

目的观察经内镜逆行胰胆管造影术(ERCP)对肝移植术后胆漏的诊断和治疗作用,并随访胆漏愈合后胆管狭窄的发生情况。方法选择经ERCP证实为肝移植术后胆漏13例患者,其中T管漏6例、吻合口漏7例。行内置管引流术6例、鼻胆管引流术2例、鼻胆管联合内置管引流术3例、十二指肠乳头括约肌切开术2例。部份患者联合应用生长激素。结果10例完整随访者胆漏愈合时间10-35d,平均15.3d,随诊胆管造影证实出现吻合口狭窄4例、肝总管狭窄3例、肝内外胆管多发性狭窄1例。胆漏愈合后有80%患者会出现不同形式的胆管狭窄。结论经内镜鼻胆管引流或内置管引流是治疗肝移植术后胆漏的有效方法。鼻胆管引流联合内置管引流除具有疗效确切、便于观察等优点外,理论上有防治鼻胆管意外脱落引起严重后果和预防后续胆管狭窄形成的作用,但其上述作用有待进一步观察。     

经内镜诊治肝移植术后胆道远期并发症

目的：探讨经内镜逆行胰胆管造影(ERCP)在诊断和治疗肝移植患者胆道远期并发症中的应用。方法：肝移植术后出现胆道远期并发症患者6例，共行ERCP 12次，根据患者的情况进行扩张、内镜下乳头切开取石、内支架置入等治疗。结果：1例胆总管结石行乳头切开后取石成功，1例胆道狭窄在胆道扩张后胆道梗阻症状解除，4例胆道狭窄合并胆总管结石的狭窄近端结石经乳头切开取出，狭窄远端结石行胆道扩张、内支架置入等治疗后取出。所有患者经治疗后胆红素、碱性磷酸酶等酶学指标均有不同程度的下降，无严重并发症发生。结论：ERCP是诊断和治疗肝移植患者胆道远期并发症安全、有效的手段。     

Endoscopic diagnosis and treatment of biliary leak in patients following liver transplantation:a prospective clinical study

Introduction As a choice of therapy, orthotopic liver trans- plantation (LT) is widely applied to end- stage liver disease. However, 13%-35% of procedures are complicated by problems of the biliary tract, the most common being stricture and leakage.[1-5] In an analysis of 259 LT recipients, Hwang et al[6] found 12 episodes of anastomotic bile leak and 42 episodes of anastomotic stenosis in 50 recipients. For choledochocholedochostomy cases, the common types of biliary leak are T-tube and an…     

Long-term prognosis of patients with endoscopically treated postoperative bile duct stricture and bile duct stricture due to chronic pancreatitis

Aim:  To compare the outcome of endoscopic therapy for postoperative benign bile duct stricture and benign bile duct stricture due to chronic pancreatitis, including long-term prognosis.
Methods:  The subjects were 20 patients with postoperative benign bile duct stricture and 13 patients with bile duct stricture due to chronic pancreatitis who were 2 years or more after initial therapy. The patients underwent transpapillary drainage with tube exchange every 3 to 6 months until being free from the tube. Successful therapy was defined as a stent-free condition without hepatic disorder.
Results:  Endoscopic therapy was successful in 90% (18/20) of the patients with postoperative bile duct stricture. The stent was removed (stent free) in 100% (20/20) of the patients, but jaundice resolved in only 10% (2/20) of patients while biliary enzymes kept increasing. Restricture occurred in 5% (1/20) of the patients, but after repeat treatment the stent could be removed. In patients with bile duct stricture due to chronic pancreatitis the therapy was successful in only 7.7% (1/13) of the patients; the stent was retained in 92.3% (12/13) of the patients during a long period. Severe acute pancreatitis occurred in 3.0% (1/33) of the patients as an accidental symptom attributable to endoscopic retrograde cholangiopancreatography (ERCP); however, it remitted after conservative treatment.
Conclusion:  Our results further confirm the usefulness of endoscopic therapy for postoperative benign bile duct strictures and good long-term prognosis of the patients.     

Endoscopic management of biliary complications after orthotopic liver transplantation

BACKGROUND: Biliary complications are a serious problem in patients after liver transplantation and often require reoperation. This study was conducted to summarize the endoscopic diagnosis and management of biliary complications after orthotopic liver transplantation (OLT). METHODS: From December 2000 to November 2003, twelve endoscopic retrograde cholangiopancreatographies(ERCPs) were performed in 7 patients after OLT at Digestive Endoscopic Center of Changhai Hospital in Shanghai, China. The therapeutic maneuvers included endoscopic sphincterotomy (EST), biliary stent placement, balloon and basket extraction, irrigation, and nasobiliary tube placement. A retrospective study was made to determine the types of biliary tract complications after OLT. The success of ERCP and therapeutic maneuvers was also evaluated. RESULTS: Biliary tract complications including biliary stricture, biliary leak, biliary sludge, and stump leak of the cyst duct were treated respectively by endoscopic sphincterotomy with sludge extraction, stricture dilation or endoscopic retrograde biliary drainage. Two of the 3 patients with proximal common bile duct stricture were successfully treated with ERCP and stent placement. Four patients with anastomotic stricture and/without bile leak were treated successfully by dilation and stent placement or endoscopic nosobiliary drainage. No severe ERCP-related complications occurred. CONCLUSIONS: ERCP is an effective and accurate approach for the diagnosis of biliary tract complications after OLT, and placement of a stent is a safe initial treatment for biliary complications after liver transplantation.

Endoscopic management of laparoscopic cholecystectomy-associated bile duct injuries

Background/purpose

The efficacy of the endoscopic management of laparoscopic cholecystectomy (LC)-associated bile duct injuries is unclear because few studies on the issue report methods matched to injury type or long-term follow-up data.

Methods

Records from our institution??s 11-year experience with the endoscopic management of LC-associated bile duct injuries were reviewed. Leakage was managed with a 5- to 7F endoscopic nasobiliary drainage (ENBD) tube for 1?week without endoscopic sphincterotomy (EST). Stricture was managed with the placement of a single 7F plastic stent for 1?C2?months without EST.

Results

Fifteen cases were experienced. Of the 11 cases (77.8%) of leakage, 7 improved clinically and on imaging after ENBD, 2 did not resolve until after the placement of a single plastic 7F stent for several more days, and 2 others with leakage and high risk for accidental ENBD removal improved after the placement of a single 7F stent. All 4 cases of stricture resolved completely after the placement of a single 7F stent. There were no severe complications of the endoscopic procedure. At long-term follow-up, no patient had recurrence of symptoms or complications on imaging.

Conclusions

ENBD for leakage and biliary stenting for strictures are safe and effective treatments for these LC-associated injuries.     

Endoscopic treatment for biliary stricture secondary to chronic pancreatitis

The causes of benign biliary stricture include chronic pancreatitis, primary/immunoglobulin G4-related sclerosing cholangitis and complications of surgical procedures. Biliary stricture due to fibrosis as a result of inflammation is sometimes encountered in patients with chronic pancreatitis. Frey's procedure, which can provide pancreatic duct drainage with decompression of biliary stricture, can be an initial treatment for chronic pancreatitis with pancreatic and bile duct strictures with upstream dilation. When patients are high-risk surgical candidates or hesitate to undergo surgery, endoscopic treatment appears to be a potential second-line therapy. Placement of multiple plastic stents is currently considered to be the best choice as endoscopic treatment for biliary stricture due to chronic pancreatitis. Temporary placement with a fully covered metal stent has become an attractive option due to the lesser number of endoscopic retrograde cholangiopancreatography (ERCP) sessions and its large diameter. Further clinical trials comparing multiple placement of plastic stents with placement of a covered metal stent for biliary stricture secondary to chronic pancreatitis are awaited.     

Endoscopic treatment of bile duct post-traumatic and post-operative lesions in children

Background and study aims: The aim of this study was to assess the significance and safety of endoscopic retrograde cholangiopancreatography (ERCP) in diagnosing and treating bile duct injuries in children.

Patients and methods: Fourteen pediatric patients, with traumatic or postoperative bile duct injury, in which ERCP was performed, were retrospectively evaluated.

Results: We performed 46 ERCP and 12 endoscopic papillotomies in children with suspected bile duct injuries. A bile stent was primarily inserted in 13 patients and there were 20 replacements. Endoscopic treatment of bile leakage without need for bile duct sutures or reconstruction was successful in 85.7%. Post ERCP complications included cholangitis and recurrent bleeding, which occurred only in two patients each.

Conclusions: ERCP and endoscopic bile stent insertion is a highly effective, minimally-invasive treatment for bile duct injury and should be included as part of the therapeutic procedures in pediatric patients with suspected bile duct injury.
