Percutaneous Transhepatic Biliary Stenting Research Articles

Biliary complications of living related pediatric liver transplant patients.

Patients who undergo living related left lateral segment liver transplants have been reported to have a high incidence of biliary complications and some studies suggest that most patients will ultimately need operative revision. We reviewed our experience with living related transplantation in pediatric recipients to examine the occurrence of biliary complications and the utility of percutaneous biliary procedures in their management. Over a 10-yr period, 48 living donor transplants were performed in 47 patients. Sixteen patients (33%) had biliary complications. Complications included 10 leaks (20%) and eight strictures (17%). Although leaks were treated predominantly with operation, other biliary complications were treated almost exclusively non-operatively. Self limited leaks that lead to biloma accumulation were most often treated via percutaneous catheter drainage and all strictures were treated using percutaneous transhepatic biliary cholangioplasty and stenting. Sixty-seven percent of biliary complications underwent non-operative biliary intervention. Most strictures were focal anastomotic strictures and were successfully treated with cholangioplasty although multiple interventions were necessary and patients required stenting for an average of 13 months. Three of eight strictures were diffuse in nature and these included the only patient who required retransplantation. Graft survival with respect to biliary complications was 94%; 1 yr, 5 yr and overall patient survival for those with biliary complications was 88, 88 and 81%, and for the entire living related group was 84, 81 and 77%, respectively. Although biliary complications are frequent in pediatric living related transplantation, they are not associated with decreased patient survival. Excepting significant bile leaks, the majority can be treated non-operatively via biliary cholangioplasty and stenting. Strictures are especially amenable to this technique which, in our experience, has been successful at decreasing or postponing the need for retransplantation.

Surgical Treatment of Biliary Tract Infections

Despite major advances in surgical and nonsurgical therapy, biliary tract infections remain a significant cause of morbidity and mortality. The two classic biliary tract infections most commonly encountered are acute cholecystitis (either calculous or acalculous) and acute cholangitis. In addition, bile leakage associated with bile duct injuries during laparoscopic cholecystectomy has become a problem not infrequently encountered by surgeons. Acute calculous cholecystitis results from a combination of mechanical, biochemical, and infectious mechanisms, initiated by stone impaction in the cystic duct. After instituting empiric antibiotics, early laparoscopic cholecystectomy should be performed. Although conversion to open cholecystectomy is more common than in chronic cholecystitis, there appears to be no increased morbidity or mortality in that setting. Acute acalculous cholecystitis usually occurs in critically ill patients and may present both a diagnostic and therapeutic dilemma. Aggressive management, however, is warranted, both because of the critical nature of illness in these patients and the high incidence of perforation. Percutaneous cholecystostomy is indicated, particularly in high-risk patients both for diagnosis and treatment. Acute cholangitis results from a combination of bactibilia and biliary obstruction. The majority of patients can be successfully managed with intravenous antibiotics and fluid resuscitation. In those patients in whom initial management is not successful, biliary drainage, which is best accomplished nonoperatively, should be instituted. There is a very limited role for early surgical intervention in acute suppurative cholangitis. Biliary leaks resulting in bile "peritonitis" or bilomas are common sequelae of laparoscopic bile duct injury. Although surgeons may feel it is necessary to operate urgently, delineation of the proximal biliary anatomy via percutaneous transhepatic cholangiography and biliary stent placement is the appropriate first step in management. This procedure will usually control the bile leak and allow delineation of the anatomy and opportune timing of definitive reconstruction.

Obstructive jaundice secondary to ruptured hepatocellular carcinoma into the common bile duct. Surgical experiences of 20 cases.

Hepatocellular carcinoma (HCC) presenting as obstructive jaundice caused by floating tumor debris in common bile duct is rare. Taiwan has a high incidence of HCC and cirrhosis. The authors report their clinical experiences and evaluate the results of different treatment modalities for this disease. A retrospective study was undertaken to review 20 patients with obstructive jaundice secondary to ruptured HCC into common bile duct during the 12 years period. All patients on initial examination had recurrent episodic jaundice or cholangitis. Jaundice was relieved by nonsurgical, percutaneous transhepatic biliary stenting in 4 patients and surgical intubation with T-tube drainage in 16. Types of treatment for those who were treated nonsurgically were percutaneous transhepatic biliary stenting in two patients, followed by transcatheter hepatic arterial embolization in another two patients. For the 16 patients who were treated surgically, the types of treatment were T-tube or Y-tube drainage in 11, T-tube drainage followed by hepatic resection in 2, T-tube drainage and hepatic arterial ligation in 1, and T-tube drainage followed by transcatheter hepatic arterial embolization in the other 2. Liver cirrhosis was the associated disease in 12 (75%). Four patients (20%) died in the hospital. The mean survival time for 12 patients with only surgical or nonsurgical biliary stenting was 3.9 months. For the three patients with percutaneous hepatic arterial embolization, the mean survival time was 8.0 months. Two patients who had undergone hepatic resection had a better postoperative survival time, with one surviving for more than 5 years. Clinical features, types of management, operative findings, and survival in 20 patients with HCC obstructing the common bile duct by tumor thrombi were reviewed. Not all patients with this disease were terminally ill. With proper management, good palliation and occasional cure are possible.

Bile duct stricture in an infant with gastroschisis treated by percutaneous transhepatic drainage, biliary stenting, and balloon dilation

A newborn twin with an antenatal diagnosis of gastroschisis underwent staged repair of the abdominal wall defect. She developed multiple fistulae due to ischemic bowel and then abdominal wall dehiscence requiring additional surgical interventions. Obstructive jaundice, first evident at 3 weeks of age, became progressively severe. A stricture of the common bile duct was diagnosed by percutaneous transhepatic cholangiography. The stricture was treated by percutaneous biliary drainage, biliary stenting, and balloon dilation of the common bile duct. These procedures, commonly used in adults for biliary decompression, may be useful alternatives to surgical intervention in infants and children with obstructive jaundice due to bile duct stricture.
