Clinical outcomes in patients with bile leaks treated via ERCP with regard to the timing of ERCP: a large multicenter study.

BACKGROUND AND AIMS: Postsurgical or traumatic bile duct leaks (BDLs) can be safely and effectively managed by endoscopic therapy via ERCP. The early diagnosis of BDL is important because unrecognized leaks can lead to serious adverse events (AEs). Our aim was to evaluate the relationship between timing of endotherapy after BDL and the clinical outcomes, AEs, and long-term results of endoscopic therapy. METHODS: We conducted a multicenter, retrospective study on patients with BDLs who underwent ERCP between 2006 and 2014. Data were assembled on patient demographics, etiology of BDL, and procedural details. Endotherapy for BDLs were classified a priori into 3 groups based on timing of ERCP from time of biliary injury: within 1 day of BDL, on day 2 or 3 after BDL, and greater than 3 days after BDL. The relationship among timing of ERCP after BDL injury and outcomes, procedure-related AEs, and patient AEs and mortality were evaluated. RESULTS: From February 2006 to June 2014, 518 patients (50% male; mean age, 51.7 years) underwent ERCP for therapy of BDLs. The etiology of the BDL was laparoscopic cholecystectomy (70.7%), post-liver transplantation (11.2%), liver resection (14.1%), trauma (2.5%), and other causes (1.5%). Endotherapy was performed by placing a transpapillary stent alone (73.5%) or with a sphincterotomy (26.5%). The timing of ERCPs was as follows: ≤1 day = 57 patients, day 2 or 3 = 140 patients, and >3 days = 321 patients. There was no statistical difference in patient demographics, etiology/site of BDL, or type of endotherapy performed among the 3 groups. On multivariate analysis there was no statistically significant difference in BDL success rate for ERCPs performed within 1 day compared with those performed on day 2 or 3 or after 3 days of bile duct injury (91.2%, 90%, and 88.5%, respectively; P = .77). Similarly, there was no significant difference in the overall patient AE rate among the 3 groups (21.1%, 22.9%, and 24.6%, respectively; P = .81). AEs in men occurred significantly more frequently when compared with women, even after adjusting for age, BDL etiology, and location of leak (27.6% vs 19.9%; OR, 1.53; P = .04). Patients whose BDL was due to a cholecystectomy had a lower AE and mortality rate compared with those who had biliary injury from other etiologies (OR, .42; P < .001). CONCLUSIONS: The overall success rates and AEs after ERCP were not dependent on the timing of the procedure relative to the discovery of the bile leak. This suggests that ERCP in these patients can usually be performed in an elective, rather than an urgent, manner.

This is the first case report of Gangrenous cholecystitis due to the insertion of endoscopic nasobiliary drainage (ENBD) tube into the cystic duct by mistake,The reason why it happened may be related to Inflammation and hypoimmunity.

Morbidity and mortality after minor bile duct injury following laparoscopic cholecystectomy.

BACKGROUND AND STUDY AIMS: Cystic duct and Luschka duct leakage after laparoscopic cholecystectomy are often classified as minor injuries because the outcome of endoscopic stenting and percutaneous drainage is generally reported to be good. However, the potential associated early mortality and risk factors for mortality are scarcely reported. The aim of this study was to describe the outcome, mortality, and risk factors for poor survival of patients with type A bile duct injury (BDI) referred to a tertiary center. PATIENTS AND METHODS: Between January 1990 and January 2012, 800 patients were referred for BDI treatment and included in a prospective database. RESULTS: Type A BDI, according to the Amsterdam and Strasberg classifications, was diagnosed in 216 patients. Treatment after referral was mainly endoscopic (n = 192 [88.9 %]) and radiologic (n = 14 [6.5 %]). Complications related to endoscopic retrograde cholangiopancreatography (ERCP) occurred in 14 patients (6.5 %). Other complications were sepsis (n = 34 [15.7 %]), cardiopulmonary (n = 22 [10.2 %]), and abscess formation (n = 15 [6.9 %]). BDI-related mortality was 4.2 % (9/216). Multivariate analysis showed age (hazard ratio [HR] = 1.04, 95 % confidence interval [CI] 1.00 - 1.07) and American Society of Anesthesiologists class 3 or 4 (HR = 5.64, 95 %CI 2.31 - 13.77) to be independent factors significantly associated with mortality. CONCLUSIONS: Type A "minor" BDI after laparoscopic cholecystectomy is associated with considerable short-term mortality related to the patient's condition at referral. Older patients and patients with ASA 3 or 4 have a significantly higher risk of mortality.

[Right hepatic artery pseudoaneurysm fistulating to the biliary tract responsible for recurrent upper gastrointestinal tract bleeding]. / Pseudoaneuryzma jaterní tepny fistulující do zlucových cest jako prícina opakovaných melén.

The paper presents a case of 51 years old patient suffering from repetitive upper intestinal tract bleedings following several months after uncomplicated laparoscopic cholecystectomy for acute cholecystitis. After a difficult diagnostic algorithm the diagnosis is set as a right hepatic artery pseudoaneurysm fistulating into the cystic duct stump. Several attempts of intraarterial embolisation (coiling) were done with only temporary effect. Finally an open surgical procedure with transligation of the aneurysm was performed with an immediate and definitive effect. No clinical signs of bleeding appeared within 6 months after the procedure. Key words: haemobilia, hepatic artery pseudoaneurysm, complication of cholecystectomy, coiling.

Stray bullet in inferior vena cava.

A young boy presented in emergency with history of being hit by a stray bullet injuring the right hypochondrium. Ultrasound of abdomen showed hemoperitoneum and the radiograph showed bullet in the pelvis. Exploratory laparotomy showed injuries to liver and cystic duct with tract leading retroperitoneally into the inferior vena cava. The bullet was found wandering inside the vena caval lumen. Stray bullets are presumed to remain limited to the soft tissues. However, the trajectory, impact velocity and the involved region ultimately determine the outcome and influence management.

Endoscopic therapy for type B surgical biliary injury in a patient with short cystic duct.

Anatomical variations of the cystic duct are well-defined. The presence of short or absent cystic duct is unusual and represents a co-factor of biliary injury especially during laparoscopic cholecystectomy. Thus, its knowledge is important to avoid ductal injury in hepato-biliary surgery. We experienced the case of a 40-year-old woman with symptomatic cholelitiasis, who underwent to laparoscopic cholecystectomy. At surgery, an accidental bile duct lesion was carried, during Calot's triangle dissection, due the particular difficulties in dissecting an extremely short cystic duct found at the junction of the common hepatic duct and common bile duct. No vascular anomalies were present. The biliary leakage from the common bile duct was intraoperative identified and subsequentially treated by the endoscopic method. Laparoscopic cholecystectomy with sequential biliary endoprosthesis insertion was completed without conversion to open surgery. The endoscopic stenting was the definitive treatment for the leakage. No evidence of biliary stent complication was observed during the follow-up. This report documents a case of short cystic duct with particular emphasis to the biliary injury risk during the laparoscopic dissection of "unusual" Calot's triangle, and examines our mini-invasive therapeutic strategies in the management of bile leakage after laparoscopic cholecystectomy.

Endoscopic sphincterotomy alone in the management of low-grade biliary leaks due to cholecystectomy.

AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is important in the diagnosis and management of postoperative bile leaks. Endoscopic sphincterotomy (ES) alone, ES with stent or nasobiliary drain (NBD) placement and stent or NBD without ES are the methods of choice. In the present study, we aimed to show the efficacy of ES alone in the management of low-grade (LGL) cystic duct stump (CDS) leaks due to cholecystectomy. METHODS: Between September 2005 and January 2008, ES was carried out on 31 patients with LGL from the CDS due to cholecystectomy who were referred to the endoscopy unit of Izmir Ataturk Training and Research Hospital. Biliary leakage was detected by biliary discharge from a tube drain inserted during the operation. In cases of retaining common bile duct stones, balloon extraction was carried out. If bile discharge continued, a stent was introduced for cessation of the leak as a second procedure. RESULTS: The success rate of ES alone was 87.1% (27 of 31 patients). In four patients (12.9%), ES alone was inadequate, therefore a stent was placed. The biliary leak ceased gradually and stopped in all patients at a mean of 11 (7-21) days. Balloon extraction of retained stones was carried out in six patients (19.6%). In two (6.5%) patients, mild hemorrhage and in two patients self-limited pancreatitis was seen (6.5%) as complications. CONCLUSION: Endoscopic retrograde cholangiopancreatography is essential in the management of postoperative biliary leaks. Endoscopic sphincterotomy alone can be the initial procedure in the treatment of LGL from the CDS due to cholecystectomy.

Double cystic duct in a child with VACTERL association: a case report.

We report the first pediatric case born with VACTERL association found to have double cystic ducts during gallbladder surgery for symptomatic cholelithiasis. Description of the anatomic variability, cholangiography images, and pathologic findings along with review of the literature is included.

Endoscopy for treating minor post-cholecystectomy biliary fistula A review of the literature.

AIM: Laparoscopic cholecystectomy for gallstone disease is the most common surgical procedures performed in Western countries and bile leaks remain a significant cause of morbidity. A recognized treatment for minor biliary injury is internal biliary decompression by endoscopic retrograde cholangiopancreatography. The aim of this study was to assess the effectiveness of endoscopic strategy in the management of minor biliary injuries. MATERIAL OF STUDY: Twenty-two patients with a bile leak following laparoscopic cholecystectomy were recorded consecutively between 2007 and 2017 and they were all treated with endoscopic approach, with ERCP in order to confirm the nature of the injury and decompress the bile duct with sphincterotomy, stent insertion, or the placement of nasobiliary drains. In 15 patients, the leak was diagnosed by persistent bile drainage, in the other 7 patients without a drain the biliary leak was suspected because of symptoms in the immediate postoperative period. RESULTS: Controlled biliary fistulae were established in all 22 patients (100%), without further intervention. A complete cholangiogram was obtained in all patients (100%). The most common sites of minor leak were the cystic duct stump and the Luschka duct, but in one patients the site of the leak was unclear. DISCUSSION: Early in the series, sphincterotomy alone or nasobiliary tube placement was performed. Subsequently patients underwent sphincterotomy with stent insertion, in order to promote preferential drainage of bile into the duodenum. The median time to resolution after successful ERCP was 4 days. Two patients underwent ERCP complicated by mild pancreatitis. The median hospital stay was 15 days (range, 10-31 days) post-laparoscopic cholecystectomy. ERCP was performed 4-6 weeks later to document healing of the leaking point and to remove the stent. Routine follow was at median 50 days. CONCLUSIONS: This review confirms that postoperative minor biliary injuries can be successful managed by endoscopic ERCP biliary decompression. KEY WORDS: Bile leak, Bile duct injury, Biliary fistula, Endoscopy, ERCP, Laparoscopic cholecystectomy.

Acquired abnormalities of the biliary tract from chronic gallstone disease.

BACKGROUND: Acquired abnormalities of the biliary tract from chronic gallstone disease are rare. The aim of this study was to examine the frequency with which these abnormalities occur and to assess the probability of encountering such an abnormality at laparoscopic cholecystectomy. STUDY DESIGN: We conducted a prospective study of all patients undergoing elective and emergency cholecystectomy under the care of one surgeon between January 1991 and December 1997. RESULTS: Biliary tract abnormalities from chronic gallstone disease were encountered in 10 (2%) of 486 patients undergoing cholecystectomy. Four were observed in patients undergoing elective laparoscopy cholecystectomy, and the remainder were observed at open cholecystectomy. Five had a cholecystocholedochal fistula (Mirizzi Syndrome Type II), and one had a stone impacted at the cystic duct-bile duct junction (Mirizzi Syndrome Type I). Two had cholecystoduodenal fistulas and two had an absent cystic duct with a normal bile duct. Both instances of an absent cystic duct were encountered at laparoscopic cholecystectomy; in one the bile duct was mistaken for the cystic duct and a 2-cm segment was excised at operation, and in the other the abnormality was recognized and confirmed by cholangiography. CONCLUSIONS: This study demonstrates a similar incidence of acquired abnormalities of the biliary tract from chronic gallstone disease to that already reported. But acquired absence of the cystic duct may occur more frequently than previously suspected. Patients with this condition are at high risk for bile duct injury during laparoscopic cholecystectomy. Clinical awareness of this problem with strict adherence to the principles taught at open cholecystectomy may prevent or reduce the severity of bile duct injury in these patients.

Laparoscopic guided cholecystectomy.

Cholecystectomy remains the most effective form of therapy for patients with symptomatic cholelithiasis. An alternative method of gallbladder removal, laparoscopic guided cholecystectomy, was attempted in 100 patients. Five patients required conversion of the laparoscopic procedure to an open laparotomy for the following reasons: discovery of a pancreatic malignancy in one patient, extensive adhesions in one, presence of an aberrant accessory right hepatic duct in one, common hepatic duct injury in one, and avulsion of the cystic duct in one. Both ductal injuries occurred during the early phase of the clinical program. In those patients undergoing laparoscopic cholecystectomy, 93 were discharged within 24 hours of surgery and 94 returned to normal activity within 1 week. Laparoscopic guided cholecystectomy appears to offer a number of advantages in patient care as well as a significant reduction in health care expenses for gallbladder disease. Appropriate training in laparoscopic surgery is necessary in order to avoid operative complications.

The endoscopic management of persistent bile leakage after laparoscopic cholecystectomy.

BACKGROUND: Bile leakage after laparoscopic biliary surgery is a surgical challenge in which endoscopy can play an important role. METHODS: A total of 26 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) in our department. Patients with evidence of major ductal injury were treated surgically. In all other cases, endoscopic sphincterotomy was performed, any retained bile duct stones were removed, and a biliary endoprosthesis or a nasobiliary catheter was inserted on a selective basis. RESULTS: ERCP was successful in 24 patients. Seven patients were treated surgically after cholangiography revealed major ductal injury. Two more patients were eventually operated on due to bile peritonitis. Of the other 15 patients, 11 had leakage from the cystic duct and four had leakage from the gallbladder bed. Bile duct stones were removed from eight patients, an endoprosthesis were inserted in five patients, and a nasobiliary catheter was inserted in two patients. Bile leakage was treated successfully in all 15 patients with no further complications. CONCLUSION: ERCP is a means of safe diagnosing the cause of a bile leakage and offers a definitive treatment in most cases.

Long-term results from laparoscopic common bile duct exploration.

BACKGROUND: The aim of this study was to evaluate the long-term results after laparoscopic common bile duct exploration (LCBDE). METHODS: A retrospective review of 175 consecutive patients who underwent attempted LCBDE between 1992 and 1999 was conducted. Laparoscopic transcystic exploration was accomplished in 110 patients and laparoscopic choledochotomy in 52 patients. Conversion to an open common bile duct exploration was required for 13 patients (7.4%). Retained common bile duct stones occurred in eight patients (4.6%). The 30-day postoperative morbidity was 6.9%, and there was no 30-day mortality. All the patients (alive and localized) received a questionnaire evaluating long-term results. RESULTS: Of the 175 patients, 169 (4 unrelated deaths and 2 patients lost to follow-up evaluation) received and 152 (90%) returned the questionnaire. The follow-up period ranged from 6 to 72 months (median, 36 months). One patient developed recurrent common bile duct stones. There were no signs or evidence of common bile duct stricture in any patient. CONCLUSION: The LCBDE procedure can be performed without increased risk of late bile duct complications.

Right hepatic artery pseudoaneurysm and cystic duct leak after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy (LC) seems to be associated with an increased risk of biliary or vascular injuries. Hepatic artery pseudoaneurysms (HAP) are rare complications of LC. HAP can occur in the early or late postoperative period. Patients with HAP present with abdominal pain, hemobilia, and liver function test (LFT) alterations. We report the case of a patient who was affected with a cystic duct stump leak associated with a right HAP and was treated by endoscopic biliary drainage and angiographic coil embolization.

Iatrogenic bile duct injuries.

BACKGROUND: The real incidence of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is not known. METHODS: Using questionnaires, we analyzed 91,232 LC performed by 170 surgical units in Brazil between 1990 and 1997. RESULTS: A total of 167 BDI occurred (0.18%); the most frequent were Bismuth type 1 injuries (67.7%). Most injuries (56.8%) occurred at the hands of surgeons who had surpassed the learning curve (50 operations). However, the incidence dropped with increasing experience; it was 0.77% at surgical departments with <50 operations vs 0.16% at departments with >500 operations. The diagnosis was made intraoperatively in 67.7%, but it was based on intraoperative cholangiography in only 19.5%. The procedure was converted to open surgery in 85.8% when the diagnosis of injury occurred intraoperatively, and laparotomy was performed in 90.7% when the injury was diagnosed postoperatively. The mean hospitalization time was 7.6 +/- 5.9 days, the major complications were stenosis and fistulas, and the mortality rate was 4.2%. CONCLUSION: The incidence of BDI after LC is similar to that reported for the open procedure. BDI increases mortality and morbidity and prolongs hospitalization; therefore, all efforts should be made to reduce its incidence.

The role of hepatic resection in the management of bile duct injuries following laparoscopic cholecystectomy.

The creation of a specialized hepatobiliary surgery unit at our medical center has resulted in referral of 16 patients with bile duct complications following laparoscopic cholecystectomy over the last 18 months. No patient required conversion to open cholecystectomy. Although no injury was recognized at the time of surgery, 15 of 16 patients became symptomatic within the first 30 days. Two patients died from sepsis and multisystem organ failure after protracted hospital courses. Endoscopic retrograde cholangiopancreatography and/or percutaneous transhepatic cholangiography determined diagnosis and level of injury. Six of seven patients with cystic duct leak underwent successful endoscopic stent placement and one patient sealed spontaneously after percutaneous drainage of a large biloma. Nine patients required surgery that included hepaticojejunostomy (five), T-tube insertion and drainage of abscess (two), or segmental hepatic resection (two). Timely recognition of bile duct complications following laparoscopic cholecystectomy is critical to a successful long-term outcome. Although the majority of cystic duct leaks can be managed with endoscopic stenting, patients with ductal injuries require hepaticojejunostomy. Segmental liver resection may serve an important role in the management of carefully selected patients with high intrahepatic injuries to avoid long-term transhepatic stenting and complications such as episodic cholangitis and late stricture formation.

Diagnostic and therapeutic interventions in post-laparoscopic cholecystectomy biliary complications.

Radiological imaging and therapeutic interventions were performed in eight patients with biliary complications following laparoscopic cholecystectomy. The diagnostic approach and the outcome of the therapeutic procedures were evaluated. Complications observed were bile leakage from the cystic duct stump (n = 2); erroneous identification of the cystic duct leading to common hepatic duct transection (n = 1) and hepatic duct ligation (n = 2); liver abscess (n = 1); and retained common duct stones (n = 2). Diagnostic ultrasonography is capable of detecting the presence of abnormal fluid collection and the diameter of the common duct with or without the presence of a stone, although bile leaks and retained common duct stones can only be demonstrated by either endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. Once a bile leak had been confirmed, therapeutic endoscopic biliary stenting was successfully applied in one patient while the other received percutaneous transhepatic biliary drainage. Definitive diagnosis of retained common duct stone was established by endoscopic retrograde cholangiopancreatography, and immediate endoscopic sphincterotomy with stone extraction was performed. Follow-up radiological imaging was done to determine the effectiveness of the therapeutic procedures applied in each patient. All our patients improved clinically, and further surgical intervention was not needed.

Is birth trauma responsible for idiopathic perforation of the biliary tract in infancy?

This case report details the clinical presentation and surgical management of a neonate with idiopathic perforation of the biliary tract. A three-day-old baby girl presented with a right-upper-quadrant mass and signs of peritonitis following a prolonged, difficult vaginal delivery. At surgery, she was found to have a perforation at the junction of the cystic and common bile duct. Simple drainage of the right upper quadrant was performed, and the patient recovered uneventfully. Early presentation and the nature of delivery suggests the possibility of birth trauma as an etiological factor in this condition.
