Percutaneous management of tumoral biliary obstruction in children

Percutaneous Management of Biliary Stones

Bile duct stone disease is the most common causes of nonmalignant bile duct obstructions. The range of common bile duct stone formation in patients with cholecystectomy is 3 to 14.7%. Hepatolithiasis, although endemic in some parts of the world, is a rare disease that is difficult to manage. Endoscopic intervention is accepted as the first-line management of common bile duct stones. However, when the bile duct cannot be cannulated for various reasons, the endoscopic procedure fails. In this circumstance, percutaneous approach is an alternative technique for the nonsurgical treatment of bile duct stones. This article reviews the indications, technique, outcomes, and complications of the percutaneous treatment of bile duct stone disease.

Percutaneous management of bile duct stones in children: results of 12 cases

PURPOSE

We aimed to evaluate the effectiveness of percutaneous transhepatic removal of bile duct stones in children.

METHODS

The study included 12 pediatric patients (4 males, 8 females; age range, 1-16 years; mean age, 6.6 years) who underwent percutaneous transhepatic removal of bile duct stones between September 2007 and December 2015. Demographic data, patient symptoms, indications for interventions, technical and clinical outcomes of the procedure, and complications were retrospectively evaluated.

RESULTS

Of 12 children, five children with cholelithiasis underwent cholecystectomy subsequently. The overall technical and clinical success rate was 100%. One patient had cholangitis as a complication during the follow-up and was treated medically.

CONCLUSION

Percutaneous transhepatic removal of bile duct stones is a safe and effective method for the treatment of children with biliary stone disease. It is a feasible alternative when the endoscopic procedure is unavailable or fails.

Percutaneous management of benign biliary disorders in children

PURPOSE

The goal of this study was to analyze the outcomes of percutaneous transhepatic management of benign biliary disorders in pediatric patients.

MATERIALS AND METHODS

This study included 11 pediatric patients who underwent percutaneous transhepatic biliary interventional procedures between September 2007 and December 2016. There were 3 males and 8 females with a mean age of 9.6±5.4 (SD)years (range: 2-17years). Technical details, complications and outcome of the procedures were evaluated.

RESULTS

The underlying pathologies were bile duct stones (n=2), bile leakage (n=4), choledochal cyst (n=3) and benign biliary stricture (n=2). The therapeutic interventional procedures were as follows; percutaneous stone removal in patients with bile duct stones, external biliary drainage in patients with choledochal cyst, bile diversion by internal-external percutaneous biliary drainage (IE-PBD) in patients with bile leakage, plastic stent placement, IE-PBD with balloon dilatation in patients with benign biliary stricture. The procedures were successful in all patients technically and clinically. One patient experienced intermittent fever.

CONCLUSION

Percutaneous transhepatic biliary interventional procedure is an effective and safe approach for the treatment of pediatric patients with bile duct stones, bile leakage, symptomatic choledochal cyst and benign biliary stricture when endoscopic procedure is unavailable or fails.

Pediatric Biliary Interventions in the Native Liver

Biliary disease in infants and children frequently presents diagnostic and therapeutic challenges. Pediatric interventional radiologists are often involved in the multidisciplinary teams who care for these patients. This article reviews several notable causes of biliary disease in children who have not undergone liver transplantation, describes the role of percutaneous interventional procedures in managing these conditions, and details applicable biliary interventional techniques.

Interventional radiology in paediatric palliative care

Paediatric palliative care is a distinct subspecialty that offers treatment to children with many types of illness, including oncological, neurological and respiratory problems. Paediatric interventional radiologists can make a useful contribution to symptom management as part of a multidisciplinary team. Interventions for pain management include local ablation or other treatment of painful lesions, image-guided nerve blocks and the insertion of devices for the delivery of analgesic drugs. Various techniques are also available for the management of ascites, pleural effusions and other symptomatic complications of the underlying disease process.

Paediatric interventional oncology

As is often the case with developments in interventional radiology (IR), widespread adoption of the newer techniques of interventional oncology has taken longer in paediatric than in adult practice. The three main applications of IR techniques in children with cancer are biopsy, regional therapy and supportive care (including the treatment of complications), and these are considered separately.
