“…Metallic stents provide a larger lumen than plastic stents for drainage and permit stent placement in multiple ducts, this being especially important in hilar structures. [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67] Controlled studies have shown that metallic stents were superior to plastic endoprostheses with regard to patency and costeffectiveness. 49 However, the results of initial studies of the use of metallic stents were disappointing because of the high rate of stent occlusion.…”

Diagnosis and non-surgical treatment of bile duct carcinoma: developments in the past decade

In the past decade, ultrasonography and magnetic resonance cholangiography have become useful modalities for the screening of bile duct cancer. Intraductal ultrasonography, using a thin-caliber (2.0 to 2.4 mm in diameter) and high-frequency (15 to 20 MHz) probe, has become a promising modality in assessing locoregional staging. For interventional therapy of unresectable bile duct carcinoma, metallic stents also became an excellent modality. However, tumor ingrowth and overgrowth into the mesh of stents are problems to be solved, and external radiation therapy is widely conducted to control the tumor. To improve the limitations of external radiation, brachytherapy, photodynamic therapy, and microwave coagulation therapy are conducted. However, these modalities are available in only a limited number of institutions even now. To predict the prognosis of the patients, approaches using molecular biology must be established.

“…The most common causes of occlusion of an uncovered metallic stent are sludge formation, proximal and distal tumor overgrowth, tumor ingrowth, and stone formation (28,29). To prevent tumor overgrowth, a safety margin of at least 2 cm should be left at each end of the upper and lower margins of the stricture (overstenting) (30,31).…”

“…In recent years, metallic biliary stents have been used to relieve jaundice in patients with unresectable biliary tract cancer. [1][2][3][4][5] In patients with resectable biliary tract cancer, intraductal ultrasonography (IDUS), using a thin high-frequency ultrasonic probe, is a promising modality for locoregional staging. [5][6][7][8][9] All these techniques require the percutaneous recanalization of the bile duct.…”

Percutaneous recanalization of the bile duct is essential for placing biliary stents and carrying out other interventions. This prospective study was performed to establish safe approaches for percutaneous recanalization of the bile duct when it had previously resulted in failure. Between July 1995 and July 1999, percutaneous recanalization of the bile duct was attempted in 58 patients with a malignant biliary stenosis. When recanalization failed, an endoscopic naso-biliary drainage (ENBD) catheter was placed across the stenosis. The procedure was again attempted along the ENBD catheter. In the period of the study, four patients underwent successful recanalization after ENBD, although attempts prior to ENBD had been unsuccessful. As a result, the success rate of recanalization in the period was 100% (58/58). When recanalization fails, the use of an ENBD catheter may provide access to the biliary tree, and the biliary stenosis can be recanalized safely.
