A Novel Technique for the Management of Persistent Biliary Fistulas Developing After Liver Hydatid Cyst Surgeries: Drain Clamping Technique.

BACKGROUND: External biliary fistula, where the residual cyst is associated with the biliary tree, is one of the most common complications after liver hydatid cyst surgery. Surgical procedures become a consideration for patients in whom the biliary fistula persists despite all endoscopic procedures. However, reoperation for biliary fistula after hydatid cyst surgery leads to additional complications and increases morbidity and mortality. AIM: This study aims to treat persistent biliary fistulas that develop after liver hydatid cyst surgery using a simple noninvasive technique. MATERIALS AND METHODS: External drainage surgery was performed on 295 patients with liver hydatid cysts. Endoscopic treatment methods were used in patients who developed biliary fistula after surgery. Despite all endoscopic treatment methods, 14 patients developed persistent biliary fistulas. These patients were subsequently treated using the drain clamping technique. FINDINGS: All persistent fistulas occluded in 11.86 days (with a range of 8-20 days). No complications were observed in the one-year follow-up visits. CONCLUSION: Drain clamping, a novel approach to the treatment of persistent biliary fistulas developed despite all available endoscopic methods, can be safely used. This technique resulted in a complete recovery in patients without the need for surgical procedures.

Broncho biliary fistula following interventional radiology for hepatic metastases.

Bronchobiliary fistulas are defined as an abnormal communication between the biliary system and the bronchial tree. They are extremely rare complications of radiofrequency or microwave ablation. A 39-year-old woman with a history of neuroendocrine pancreatic carcinoma suffering from liver metastasis was treated with microwave ablation (MWA). In this case report, we present a case of intractable biliptysis from a bronchobiliary fistula secondary to an MWA. The patient was diagnosed by endoscopic retrograde cholangiopancreatograph and hepatobiliary scintigraphy. Treatment involved a right hemihepatectomy, a redo-hepaticojejunostomy, and the surgical placement of a transhepatic drain. After 6 weeks of drain placement, this could be removed. The fistula was thus successfully treated.

The management of thoracobiliary fistulas in children: a systematic review.

Thoracobiliary fistula (TBF) is a rare condition, in which an atypical communication between the bronchial tree and the biliary tree is present. A comprehensive literature search was conducted on Medline, Embase and Web of Science databases for studies reporting TBF in children. Data regarding patient demographics, site of fistula presentation, preoperative diagnostic procedures needed, and treatment modalities employed were extracted for further analysis. The study pool consisted of 43 studies incorporating 48 cases of TBF. The most frequent symptom was bilioptysis (67%), followed by dyspnea (62.5%), cough (37.5%) and respiratory failure (33%). Regarding the origin of fistula, the left hepatic duct was involved in 29 cases (60.4%), the right hepatic duct in 4 cases (8.3%), and the hepatic junction in 1 case (2%). Surgical management was employed in 46 patients (95.8%). Fistulectomy was performed in 40 patients (86.9%), lung lobectomy or pneumonectomy in 6 (13%), Roux en Y hepaticojejunostomy in 3 (6.5%), and decortication or drainage in 3 cases (6.5%). Three patients died (overall mortality 6.3%), while 17 patients suffered from postoperative complications (overall morbidity 35.4%). TBF in children is a rare but morbid entity which evolves as a result of congenital malformation in the majority of cases. Preoperative imaging of the biliothoracic communication and proper surgical treatment are the components of current management.

Cholecystogastric fistula diagnosed by endoscopic ultrasonography.

A case of a patient with symptoms of gastric obstruction secondary to cholecystogastric fistula is presented and a brief review of the literature is done.

Bronchobiliary fistula after stenting of biliary duct as the management of iatrogenic bile duct injury during elective cholecystectomy.

BACKGROUND: Bronchobiliary fistula is a rare and complex entity defined by an abnormal communication between the biliary and bronchial systems. The etiopathogenesis is not completely understood, but the most common factors implicated are hepatobiliary tumors, biliary obstruction, iatrogenic damage or trauma. METHODS: Here we present a case of a 69-year-old man that developed a bronchobiliary fistula and a pulmonary abscess after migration of a bile duct stent placed as part of the treatment of an iatrogenic bile duct injury that occurred during elective cholecystectomy. RESULTS: A conservative approach, that included broad-spectrum antibiotic, removal of the stent, and sphincterotomy, was enough for the closure of the fistula and resolution of the symptoms. CONCLUSION: We emphasize the importance of prompt recognition of this entity and a concerted therapeutic strategy to optimize the probability of success, avoiding the destructive consequences of the bile in the pulmonary parenchyma and septic complications.

Outcome of combined pancreatic and biliary fistulas after pancreatoduodenectomy.

BACKGROUND: Postoperative pancreatic fistula (POPF) as well as postoperative biliary fistula (POBF) are considered the main source of postoperative morbidity and mortality after pancreatoduodenectomy (PD). However, little is known about the incidence and complications of combined POPF/POBF compared to isolated POPF or POBF. METHODS: This single-center study investigated retrospectively the incidence and postoperative outcome of combined POPF/POBF compared to isolated fistulas following PD in a tertiary German pancreatic center between 2009 and 2018. RESULTS: A total of 678 patients underwent PD for benign and malignant periampullary lesions. Combined fistulas occurred in 6%, isolated POPF in 16%, and isolated POBF in 2%. Pancreatic ductal adenocarcinoma and chronic pancreatitis had a protective effect on the occurrence of combined fistulas, whereas serous cystadenoma and pancreatic metastasis were risk factors. Morbidity (Grade C fistula, post-pancreatectomy hemorrhage, revisional surgery) and mortality was significantly higher in patients with combined fistulas than in those with isolated fistula. Moreover, the duration of ICU stay was longer. CONCLUSIONS: A combined POPF/POBF is associated with a significant increase of morbidity and mortality compared to isolated fistulas after PD. Early surgical revision in these patients may improve the postoperative survival rate.

[Hemobilia as a sign of arterio-biliary fistula]. / Gemobiliya kak proyavlenie arteriobiliarnoi fistuly.

Hepatic artery aneurysms (HAA) are rare (20% of all visceral arteries). Most often, HAAs are asymptomatic and detected at autopsy. However, their ruptures and/or bleeding following pressure ulcers in visceral gastrointestinal organs are a significant clinical and diagnostic problem. We present 2 patients with obstructive jaundice and hemobilia. Diagnostics revealed aneurysm of the right hepatic artery with arterio-biliary fistula. Life-threatening hemobilia is a consequence of HAA rupture into biliary system. Endovascular approach is preferable for HAA without clinical manifestations. Awareness of this disease is important for early detection and active surgical intervention before possible complications.

[Intraluminal endoscopy for biliary duodenal obstruction]. / Vnutriprosvetnaya endoskopiya pri biliarnoi duodenal'noi neprokhodimosti.

Cholelithiasis complicated by cholecystoduodenal fistula and small bowel biliary obstruction is an absolute indication for surgical treatment. Modern possibilities of intraluminal endoscopy (electrohydraulic lithotripsy) made it possible to avoid intra-abdominal access (laparotomy, laparoscopy) and postoperative complications. Finally, rapid rehabilitation was noted.

Role of laparoscopy in the treatment of internal biliary fistulas in a high-volume center and a review of the literature.

BACKGROUND: Biliary fistulas may result as a complication of gallstone disease. According to their tract, abdominal internal biliary fistulas may be classified into cholecystobiliary and bilioenteric fistulas. Surgical treatment is challenging and requires highly trained surgeons with high preoperative suspicion. Conventional surgery is still of choice by most of the authors. However, laparoscopy is emerging as a minimally invasive alternative. We investigated the surgical approach, conversion rate, and outcomes according to the type of biliary fistula. METHODS: We retrospectively reviewed 11,130 laparoscopic cholecystectomies, 31 open cholecystectomies, and 31 surgeries for gallstone ileus at our institution from May 2007 to May 2020. We diagnosed internal biliary fistula in 73 patients and divided them into two groups according to their fistulous tract: cholecystobiliary fistula and bilioenteric fistula. We described demographic characteristics, preoperative imaging modalities, surgical approach, conversion rates, surgical procedures, and outcomes. We additionally revised the literature and compared our results with 13 studies from the past 10 years. RESULTS: There were 22 and 51 patients in the cholecystobiliary and bilioenteric groups, respectively. Our preoperative suspicion of a fistula was 80%. We started 88% of procedures by laparoscopic approach. The effectiveness of laparoscopy in the resolution of internal biliary fistula was 40% for cholecystobiliary fistula and 55% for bilioenteric fistulas. The most frequent cause for conversion to laparotomy was the difficulty to identify anatomical features, in addition to the need to perform a Roux en-Y hepaticojejunostomy. Choledocholithiasis was not associated with an increase in conversion rates. CONCLUSIONS: Laparoscopic resolution of a biliary fistula is still a matter of controversy. Despite the high conversion rates, we believe that a great number of patients benefit from this minimally invasive technique. A high preoperative suspicion and trained surgeons are vital in the treatment of internal biliary fistulas.

Hemobilia due to porto-biliary fistula complicating endoscopic retrograde cholangiopancreatography after a recent liver transplantation.

A 60-year-old woman with autoimmune hepatitis submitted to liver transplantation presented with a biliary anastomotic stenosis. An endoscopic retrograde cholangiopancreatography (ERCP) was complicated with a porto-biliary fistula due to the misplacement of a biliary stent. After multidisciplinary discussion, and the stent was endoscopically removed while a percutaneous transhepatic fully-covered self-expanded metal stent was placed in portal vein. Iatrogenic porto-biliary fistula following biliary stent placement is a rare and potentially life-threatening ERCP complication. In a suspected stent-related portal vein injury, this multidisciplinary strategy combining gastroenterology and radiology proved to be an effective and safe minimally invasive technique avoiding catastrophic consequences.

Revisiting Quincke's Triad: A Case of Idiopathic Hepatic Artery Aneurysm Presenting with Obstructive Jaundice.

INTRODUCTION: Hepatic artery aneurysm (HAA) is a rare occurrence. Quincke's triad of hemobilia; abdominal pain, obstructive jaundice, and upper gastrointestinal (GI) bleeding could be detected in one-third of HAA patients. CASE PRESENTATION: We present a case of HAA with all signs of Quincke's triad and shock. The diagnosis of HAA was enforced by CT angiography. An urgent open surgical approach was elected by the surgical team. The patient underwent an uneventful resection of the HAA, and primary repair of the CHA followed with bilioenteric reconstruction. CONCLUSIONS: Recognizing the signs of Quincke's triad aids in prompt diagnosis of hemobilia in HAA, which suggests a rupture of the aneurysm or fistula formation into the biliary tree that would need urgent management by both vascular and HBP surgeons.

Jaundice as a clinical presentation in liver hydatidosis increases the risk of postoperative biliary fistula.

PURPOSE: Echinococcosis, also known as hydatidosis, is a zoonosis that is endemic in many countries worldwide. Liver hydatid cysts have a wide variety of clinical manifestations, among which obstructive jaundice is one of the rarer forms. The aims of the study were to analyze the preoperative management of these patients and to record the kind of surgical treatment performed and the short- and long-term postoperative results. METHODS: A retrospective two-center observational study of patients operated upon for liver hydatidosis with initial symptoms of obstructive jaundice. Preoperative characteristics, surgical data, and postoperative complications, including biliary fistula, were recorded. RESULTS: Of 353 patients operated upon for liver hydatidosis, 44 were included in the study. Thirty-five patients (79.6%) were defined as CE2 or CE3 in the World Health Organization (WHO) classification. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 25 patients (56.8%) and identified intrabiliary communication in 29. Radical surgery was carried out in 29 of the total sample (65.9%). Severe postoperative complications (Clavien-Dindo grade IIIA or higher) were recorded in 25% of patients. The factors associated with greater postoperative morbidity were age above 65 (HR 8.76 [95% CI 0.78-97.85]), cyst location (HR 4.77 [95% CI 0.93-24.42]), multiple cysts (HR 14.58 [95% CI 1.42-149.96]), and cyst size greater than 5 cm (HR 6.88 [95% CI 0.95-50]). CONCLUSION: The presentation as obstructive jaundice causes greater postoperative morbidity. The main postoperative complication in these cases, despite radical surgery, is biliary fistula. In our series, routine preoperative ERCP did not show any benefit.

Chronic cough caused by choledochoduodenal fistula: a case report.

BACKGROUND: Chronic cough is characterized by cough as the only or main symptom, with a duration of more than 8 weeks and no obvious abnormality in chest X-ray examination. Its etiology is complex, including respiratory disease, digestive system disease, circulation system disease, and psychological disease. Although a set of etiological diagnosis procedures for chronic cough have been established, it is still difficult to diagnose chronic cough and there are still some patients with misdiagnosis. CASE PRESENTATION: We present a case of a 54-year-old female patient who had chronic cough for 28 years. Physical examination had no positive signs and she denied any illness causing cough like tuberculosis, rhinitis. Recurrent clinic visits and symptomatic treatment didn't improve the condition. Finally, gastroscopy identified the possible etiology of choledochoduodenal fistula that was proved by surgery. And after surgery, the patient's cough symptoms were significantly improved. CONCLUSION: We report a rare case of chronic cough caused by choledochoduodenal fistula which demonstrates our as yet inadequate recognition of the etiology and pathogenesis. Written informed consent was obtained from the patient.

Spontaneous Biliary-Enteric Fistulas and Associated Complications: An Overview.

Spontaneous biliary-enteric fistula (SBEF) is an abnormal communication between the biliary tree and the gastrointestinal tract which develops as a result of biliary or gastrointestinal disease. Iatrogenic fistulas, due to surgery or instrumental exploration, are not included in this definition. R. Colombo, in 1559, was the first to describe SBEF as an occasional finding during an autopsy. In almost 90% of cases the cause of SBEF is chronic recurrent cholelithiasis. Less common causes are penetrating peptic ulcers and neoplastic infiltration from the biliary or gastrointestinal tract. The most common type of SBEF is cholecystoduodenal fistula and the least common is choledochoduodenal fistula. There are various complications associated with SBEF but often these are not promptly recognized by patients or physicians and diagnosis and treatment may be delayed for years. The most important complication, which can be considered pathognomonic for SBEF, is gallstone ileus which manifests clinically as acute or chronic mechanical intestinal obstruction. Gallstone ileus, a rather rare complication of a rather common pathology, biliary lithiasis, is found in 0.000015% of hospitalized patients but in 0.0003% of surgical patients. It is mainly found in women over the age of 65, with a male to-female ratio of 1:5. There are various forms of occlusion, related to the sites of gallstone impaction, with various clinical characteristics and degrees of severity. These include Bouveret syndrome ( 10% of cases) with impaction in duodenum or pylorus, and the more common Barnard's syndrome (5-75% of cases) in which the site of impaction is in the terminal ileum right before Bauhin's valve. For diagnosis, the radiological signs which make up Riglerâ??s triad or tetrad, are essential, and are best visible on magnetic resonance. The the gold standard is contrast-enhanced computed tomography scan. Regarding the surgical management, one-stage simple enterolithotomy is reserved for the oldest patients and the most severe cases. Nowadays, is performed more and more frequently by laparoscopy. In more favorable cases radical treatment of the occlusion, the biliary lithiasis and the SBEF is recommended, either as a one-stage procedure or in two stages with the second procedure performed after few weeks.

Comparison between transpancreatic sphincterotomy and needle-knife fistulotomy in difficulty biliary access, a retrospective study in Taiwan.

BACKGROUND: Selective deep biliary cannulation is the first and the most important step before further biliary therapy. Transpancreatic sphincterotomy (TPS), and needle knife fistulotomy (NKF) were commonly used in patients with difficult cannulation, but few studies compare the outcome between TPS and NKF. METHODS: A total of 78 patients who met the criteria of difficult cannulation in the National Taiwan University hospital from October 2015 to October 2017 were retrospectively reviewed. Their baseline demographics, success rate of biliary cannulation, and the rate of adverse events were assessed. RESULTS: 31 patients and 47 patients underwent TPS and NKF for difficult biliary access, respectively. The characteristics of the 2 groups were similar, but patients in TPS group had more frequent pancreatic duct cannulation. Bile duct cannulation was successful in 23 patients (74.2%) in the TPS group and 39 (83.0%) in the NKF group (P = 0.34). There was no difference between the TPS and NKF in the rate of adverse events, including post-ERCP pancreatitis (PEP) (16.1% vs. 6.4%, p = 0.17), and hemorrhage (3.2% vs. 8.5%, p = 0.35). No perforation occurred. CONCLUSIONS: Both TPS and NKF have good biliary access rate in patient with difficult cannulation. TPS has acceptable successful rate and similar complication rate, compared with NKF.

Anesthesia management in neonatal congenital bronchobiliary fistula: case report and literature review.

BACKGROUND: There is very little published literature and none that discussed care in a neonate regarding anesthetic risk and management of neonate with congenital bronchobiliary fistula during thoracoscopy and thoracotomy. This article analyzes related risk factors and literature review from perioperative ventilation, circulation and other aspects of management. CASE PRESENTATION: A neonate diagnosed as congenital bronchobiliary fistula combined with severe chemical pneumonia, consolidation of the lungs, and infection was facing the risk of anaesthesia under thoracoscopy exploration surgery, who experiened more than 20 days diagnostic period before operation. Many risk factors have led to conversion from minimally invasive surgery to thoracotomy, including persistent hypoxemia, hypercapnia, difficult surgical exposure and extremly difficulty of intraoperative ventilation management. Anesthesia maintenance after conversion to open access remained problematic. Fortunately the patient showed no sign of any adverse CNS effects after 4 months of follow-up. CONCLUSIONS: The most prominent anesthesia challenges are hypoxemia, increased airway resistance, impaired ventilation, and the risk of metabolic acidosis. Close cooperation among the entire neonatal medical team is the key factors in successful management of this rare case.

A serious complication of liver hydatid cysts in children: cystobiliary fistulas.

AIM: We aimed to determine predictive factors for predicting cystobiliary fistulas (CBF) in children after treatment of liver hydatid cyst (LHD). METHODS: The records of patients who were treated for LHD between 01.06.2009 and 1.06.2019 were retrospectively reviewed. Age, sex, laboratory test results, size and number of cysts, method of first intervention (percutaneous or surgery), whether or not CBF developed and how it was treated were investigated. Among findings, those could be predictive were investigated. Data were evaluated with SPSS 21.0 program, p < 0.05 was considered significant. RESULTS: Of the 97 patients, 48 (49.5%) were male, 49 (50.5%) female, the mean age was 11.2 years, Eighty patients had right (82.5%), 13 had left, and 4 had bilobar involvement. As first intervention, surgery was performed in 39 (40.2%); percutaneous treatment was performed in 58 (59.8%) patients. In 8 patients (20.5%) in surgery group and in 6 patients (10.3%) in percutaneous group, totally in 14 patients (14.4%), CBF developed. The mean cyst diameter of CBF-developed group was 114.36 mm, and of CBF-undeveloped group was 74.30 mm. There was no statistically significant differences between groups in terms of age, sex, involved lobe, other organ involvement, and preoperative results (p > 0.5). There was a significant relationship between the cyst diameter and the rate of CBF development in both surgical and percutaneous groups (p < 0.05). ROC analysis was performed, and the cut-off value for the development of CBF detected as 69 mm for children. Since obstructive jaundice seen in adults is not common in children, an increase in liver function tests and bilirubin levels were not seen in our patients. CONCLUSION: A significant correlation was found only between the size of the cyst and developing CBF. Cysts greater than 69 mm have a higher risk of developing CBF after both percutaneous and surgical treatment and should be closely monitored.

[Right hepatic bile duct injury: a single stage combined laparoscopic-endoscopic treatment]. / Lesión quirúrgica del conducto hepá tico derecho: tratamiento combinado laparoscópico-endoscópico.

Treatment of bile ducts injuries (BDI) treatment, combining minimally access surgical techniques, although their benefits, has been scarcely reported. We described a combined laparoscopic-endoscopic procedure, carried out in a patient with postoperative right hepatic duct (RHD) injury associated to laparoscopic cholecystectomy. Based on a clinical case description, we illustrate the surgical technique and assess their applicability and results. A biliary fistula was identified employing laparoscopic cholangiography and a metallic clip applied, producing RHD occlusion, was retrieved under fluoroscopic guidance. A biliary "rendezvous" maneuver was done for positioning an endoscopic biliary stent. The biliary fistula disappeared within two weeks and during 40-months of follow-up the patient remains asymptomatic. Laparoscopic-endoscopic approach, although technically demanding, resulted effective to treat this patient. A Continuous follow-up is essential for evaluating the long-term results.

Arterio-biliary fistulas: What to choose as endovascular treatment?

Objectives Endovascular procedures are the treatment of choice in cases of intrahepatic fistulas. Arterio-biliary fistulas are the rarest and most difficult to treat, due to high risk of infection. Methods Eight cases of persistent hemobilia that developed as a result of arterio-biliary fistulas are presented. Five cases developed as a result of iatrogenic injury, two cases as a result of chronic infection, one case as a consequence of trauma. Results Patients were treated using endovascular embolization or combined endovascular and endoscopic biliary tract revision. The results were monitored after six to seven days and one month after embolization. The embolizations were considered effective in all cases. One patient had four asynchronous fistulas requiring separate treatments sessions. Four patients required a revision of their biliary ducts after embolization and restoration of patency. In one patient, a migration of the coil to biliary ducts occurred. Conclusion Endovascular treatment of arterio-biliary fistulas is safe and effective. The use of embolization with soft and biodegradable materials like histoacrylic glue or thrombin may be the optimal method of treatment in comparison with coils which have a risk of migration or chronic infection.
