恶性胆道梗阻是由胆道或其他转移性恶性肿瘤导致的胆道梗阻性疾病,常以黄疸、胆汁淤积及胆管炎为表现,大于50%的患者为进展期疾病,失去根治性手术的机会。因此,缓解胆道梗阻是姑息性治疗的重要部分。内镜下胆道支架置入是一个行之有效的措施,包括塑料支架、金属支架、覆膜支架及药物洗脱支架等。其他技术如超声内镜引导下胆管引流术、内镜下射频消融术、胆管腔内近距离放射治疗、内镜下光动力治疗等,增强了内镜下逆行胰胆管造影在恶性胆道梗阻疾病中的治疗作用。此文就胆管支架的发展及内镜下恶性胆道梗阻治疗的新进展作一综述。 相似文献

Twenty patients with chronic pancreatitis and signs of biliary obstruction were treated by endoscopic placement of self expandable metal mesh stents, and followed up prospectively. Eleven had been treated previously with plastic endoprostheses. All had persistent cholestasis, seven patients had jaundice, and three overt cholangitis. Endoscopic stent placement was successful in all cases. No early clinical complication was seen and cholestasis, jaundice or cholangitis rapidly resolved in all patients. Mean follow up was 33 months (range 24 to 42) and consisted of clinical evaluation, ultrasonography, and endoscopic retrograde cholangiopancreatography (ERCP). In 18 patients, successive ERCPs and cholangioscopies have shown that the metal mesh initially embeds in the bile duct wall and is rapidly covered by a continuous tissue by three months. The stent lumen remained patent and functional throughout the follow up period except in two patients who developed epithelial hyperplasia within the stent resulting in recurrent biliary obstruction, three and six months after placement. They were treated endoscopically with standard plastic stents with one of these patients ultimately requiring surgical drainage. No patient free of clinical or radiological signs of epithelial hyperplasia after six months developed obstruction later. This new treatment could become an effective alternative to surgical biliary diversion if further controlled follow up studies confirm the initial impression that self expandable metal mesh stents offer a low morbidity alternative for longterm biliary drainage in chronic pancreatitis without the inconvenience associated with plastic stents. 相似文献

Biliary drainage in patients with malignant biliary obstruction relieves jaundice and prevents the development of cholangitis or hepatic failure from biliary obstruction. Therefore, this may result in better quality of life along with survival prolongation. Biliary stent placement is an effective and safe measure for biliary decompression and is preferred than bypass surgery in high risk patients. Entero-biliary perforation-communication is one of the rare complications of biliary stent. We herein report a case of duodeno-biliary perforation-communication in patient with distal cholangiocarcinoma who presented with duodenal ulcer and obstruction, occurring 4 years later from the metallic biliary stent insertion. Patient was managed with a pyloric metal stent and conservative care. 相似文献

Biliary drainage is a standard procedure for cholangitis or obstructive jaundice due to biliary obstruction. However, criterion for the selection of types of drainage tube is not established. The authors analyzed the types of drainage tube used in the University of Tokyo, Tokyo, Japan, during the month of June 2005, and they treated 63 cases. For drainage for cholangitis (31), the authors used endoscopic naso‐biliary drainage (ENBD) tube in 74.1% and plastic stent in 25.9%. In contrast, for the cholestesis cases (16), the authors used ENBD tube in 37.5% and plastic stent in 63.5%. For the unresectable biliary malignancy cases (8) with improved jaundice, the authors used covered metallic stent in seven distally stricture cases and uncovered metallic stent in one proximally stricture case. The remaining eight cases received plastic stent placement. There were six cases of residual common bile duct stones and two cases of prevention of cholangitis after papillectomy. For the patients with unresectable biliary malignancies at distal portion, the authors consider that covered metallic stent is a standard endoprosthesis. For drainage for cholangitis, the authors used ENBD tube because bile juice flow is able to be checked any time. However, the authors used plastic stent rather than ENBD tube for the drainage of cholestesis. A larger study for selection of drainage tube for these aspects is needed in the future. 相似文献

Together with biliary drainage, which is an appropriate procedure for unresectable biliary cancer, biliary stent placement is used to improve symptoms associated with jaundice. Owing to investigations comparing percutaneous transhepatic biliary drainage (PTBD), surgical drainage, and endoscopic drainage, many types of stents are now available that can be placed endoscopically. The stents used are classified roughly as plastic stents and metal stents. Compared with plastic stents, metal stents are of large diameter, and have long-term patency (although they are expensive). For this reason, the use of metal stents is preferred for patients who are expected to survive for more than 6 months, whereas for patients who are likely to survive for less than 6 months, the use of plastic stents is not considered to be improper. Obstruction in a metal stent is caused by a tumor that grows within the stent through the mesh interstices. To overcome such problems, a covered metal stent was developed, and these stents are now used in patients with malignant distal biliary obstruction. However, this type of stent has been reported to have several shortcomings, such as being associated with the development of acute cholecystitis and stent migration. In spite of these shortcomings, evidence is expected to demonstrate its superiority over other types of stent. 相似文献

Only 20–30% of patients with hilar cholangiocarcinoma (CC) are candidates for potentially curative resection. However, even after curative (R0) resection, these patients have a disease recurrence rate of up to 76%. The prognosis of hilar cholangiocarcinoma (CC) is limited by tumor spread along the biliary tree leading to obstructive jaundice, cholangitis, and liver failure. Therefore, palliative biliary drainage may be a major goal for patients with hilar CC. Endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is an established method for palliation of patients with malignant biliary obstruction. However, there are patients for whom endoscopic stent placement is not possible because of failed biliary cannulation or tumor infiltration that limits transpapillary access. In this situation, percutaneous transhepatic biliary drainage (PTBD) is an alternative method. However, PTBD has a relatively high rate of complications and is frequently associated with patient discomfort related to external drainage. Endoscopic ultrasound‐guided biliary drainage has therefore been introduced as an alternative to PTBD in cases of biliary obstruction when ERCP is unsuccessful. In this review, the indications, technical tips, outcomes, and the future role of EUS‐guided intrahepatic biliary drainage, such as hepaticogastrostomy or hepaticoduodenostomy, for hilar biliary obstruction will be summarized. 相似文献

Endoscopic biliary drainage (EBD) may be unsuccessful in some patients, because of failed biliary cannulation or tumor infiltration, limiting endoscopic access to major papilla. The alternative method of percutaneous transhepatic biliary drainage carries a risk of complications, such as bleeding, portal vein thrombus, portal vein occlusion and intra‐ or extra‐abdominal bile leakage. Recently, endoscopic ultrasonography (EUS)‐guided biliary stent placement has been described in patients with malignant biliary obstruction. Technically, EUS‐guided biliary drainage is possible via transgastric or transduodenal routes or through the small intestine using a direct access or rendezvous technique. We describe herein a technique for direct stent insertion from the duodenal bulb for the management of patients with jaundice caused by malignant obstruction of the lower extrahepatic bile duct. We think transduodenal direct access is the best treatment in patients with jaundice caused by inoperable malignant obstruction of the lower extrahepatic bile duct when EBD fails. 相似文献

Background and Aim: The aim of this study was to evaluate the efficacy and safety of one‐step percutaneous transhepatic insertion of the Express LD stent, a balloon‐expanding stainless steel stent used for the management of distal artery stenosis in the treatment of obstructive jaundice caused by various inoperable malignancies. Methods: Seventy‐one consecutive patients with unresectable malignant biliary obstruction who underwent Express LD stent placement between 2007 and 2010 at our institute were reviewed. Results: Mean stent patency was 165 ± 144 days and mean patient survival was 180 ± 156 days, while the cumulative stent patency rate and patient survival rate at 6 and 12 months were 79% and 65%, and 38% and 16%, respectively. Stents were successfully placed in all cases without any stent migration or misplacement. Stent failure occurred in 14 patients (20%), and 16 complications were observed, including 12 cholangitis (17%), two cholecysitis (3%), and two pancreatitis (3%). Y‐configuration stenting for hilar bile duct obstruction was the only independent prognostic factor for stent failure. Conclusions: One‐step percutaneous transhepatic insertion of the Express LD stent is effective and safe for the management of obstructive jaundice caused by inoperable malignancies. 相似文献

BACKGROUND: The efficacy of polyurethane-covered metal expandable stents for treatment of neoplastic distal biliary obstruction was analyzed. METHODS: Twenty-one patients with unresectable malignant tumors involving the mid to distal bile duct who were seen with obstructive jaundice were consecutively enrolled. Eighteen patients underwent endoscopic implantation of a polyurethane-covered metal stent and 3 patients underwent transhepatic insertion because of duodenal obstruction. The stent patency, complications, and patient survival were analyzed. RESULTS: Effective biliary decompression was achieved in all patients. Adverse events were minor: mild pancreatitis (1) and cholecystitis (2) occurred within 7 days of stent insertion. Mean survival and stent patency were 233 days and 206 days, respectively. Stent occlusion occurred in 3 patients (14%) after a mean of 188 days. Tumor ingrowth through the stent mesh was not observed. However, 2 stents were occluded by tumor overgrowth and 1 by compacted alimentary debris. CONCLUSIONS: A polyurethane membrane may prevent tumor ingrowth and reduce the occlusion rate for expandable metal stents implanted in patients with malignant obstruction of the distal bile duct. 相似文献

AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. 相似文献

Obstructive jaundice often develops in patients with unresectable malignancy in and around the head of the pancreas. Duodenal obstruction can also occur in these patients, and usually develops late in the disease course. Palliation of both malignant biliary and duodenal obstruction is traditionally performed with surgical diversion of the bile duct and stomach, respectively. With the advent of nonsurgical palliation of biliary obstruction using endoscopic transpapillary expandable metal stent placement, a similar approach can be used to palliate duodenal obstruction by placement of expandable metal gastroduodenal stents. Endoscopic palliation can be achieved in patients who require relief of both biliary obstruction and duodenal obstruction, although this can be technically difficult to achieve depending on the level of duodenal obstruction in relation to the major papilla. This article reviews the endoscopic approaches for combined palliative relief of malignant biliary and duodenal obstruction. 相似文献
