BACKGROUND.
This study was conducted to evaluate the rate of regression of bilirubin after stent placement for malignant biliary obstruction.METHODS.
Records were reviewed from October 2002 to September 2005 for patients who underwent endoscopic retrograde cholangiopancreatography with stent placement. The time to achieve a bilirubin level ≤2 mg/dL was the primary endpoint because this is the level required by most chemotherapy protocols. Patient variables included type of cancer, liver metastasis, recent chemotherapy, baseline creatinine, and international normalized ratio (INR). Stent variables included type, dimension, stricture location, and sphincterotomy.RESULTS.
In total, 156 patients were included in the analysis: Ninety‐three patients achieved a poststent bilirubin level ≤2 mg/dL, 29 patients failed because of stent failure, and 34 patients failed because of inadequate follow‐up. The time required for 80% of patients to achieve normalization was more than doubled in those who had prestent bilirubin levels ≥10 mg/dL (6 weeks) compared with those who had prestent bilirubin levels <10 mg/dL (3 weeks). The following variables were identified as statistically significant: prestent bilirubin level, stricture location, liver metastasis, and INR. The cancer type, recent chemotherapy, stent type and diameter, and sphincterotomy were not statistically significant variables.CONCLUSIONS.
The rate of bilirubin normalization after biliary stenting was highly dependent on the prestent bilirubin level. Endoscopic intervention should be considered in patients who fail to achieve adequate normalization of serum bilirubin in 6 weeks if prestent bilirubin level was ≥10 mg/dL and in 3 weeks if their prestent bilirubin level was <10 mg/dL. Independent variables, such as diffuse liver metastases, stricture outside the common bile duct, and elevated INR had predictive value for bilirubin normalization.

Fifteen patients with malignant biliary obstruction from carcinoma of the bile ducts, gallbladder, and pancreas (Group I) or metastatic disease (Group II) were treated with intraluminal radiation therapy (ILRT) at Memorial Sloan-Kettering Cancer Center. In 11 cases ILRT was used as a central boost in combination with 3000 cGy external beam radiation therapy (ERT). No significant treatment toxicity was observed. Cholangiographic response was observed in 2 of 12 evaluable patients. In no patient was long-term relief of jaundice without indwelling biliary stent achieved. Survival from treatment in eight Group I patients treated with ILRT +/- ERT was 3 to 13 months (median, 4.5). Survival in seven similarly treated Group II patients was 0.5 to 8 months (median, 4.0). Additional data for ten similar patients referred for ILRT but treated with ERT alone are presented. Analysis of this and other reports indicate the need for prospective controlled trials of the role of this regimen in the management of malignant biliary obstruction before wider application can be recommended. 相似文献

Self-expanding metal stents (SEMS) are currently the standard for palliation of malignant dysphagia. Innovations in stent technology, including the advent of retrievable stents and the development of self-expanding plastic stents (SEPS), show promise to increase the possible applications for esophageal stents. This article reviews the indications and usage of both SEMS and SEPS in patients with malignant dysphagia as well as the potential complications of their use. 相似文献

MELLER M.T., ARTS G.R.J. & DEAN J.R. (2010) European Journal of Cancer Care 19 , 664–668 Outcomes in percutaneous stenting of non‐hepato‐biliary/pancreatic malignant jaundice The aim of this study is to review the practice and outcomes at our institution of percutaneous transhepatic placement of metallic biliary stents for non‐hepato‐biliary/pancreatic (non‐HBP) malignant obstructive jaundice. A retrospective review was performed of the records of all patients undergoing transhepatic stenting for non‐HBP malignant obstructive jaundice over a 7‐year period. A total of 25 patients were successfully stented and linear regression analysis of a variety of demographic, clinical and laboratory markers against survival was performed. Survival after stenting varied from 1 to 1354 days (median 58, mean 152). An initial bilirubin level less than 300 µmol/L (P= 0.01) and a reduction of greater than 50% in bilirubin post stenting (P= 0.02) were strong predictors of improved survival. Older patients survived longer than younger ones (P < 0.01). There was a weak association of survival with an albumin >30 g/L (P= 0.06), but no statistically significant correlation with creatinine or haemoglobin levels or active tumour treatment after stenting. There were few major complications from the procedures. Transhepatic metallic biliary stenting for non‐HBP malignant biliary obstruction is a safe and effective procedure, and with careful patient selection, significant periods of survival and palliation of jaundice can be achieved. 相似文献

We evaluated the effect of biliary endoprotheses for 20 malignant stenosis patients by an expandable metallic stent and hydrophilic heparinized tube (H-PSD) connected to an implantable port (IP), which reduces bacterial adherence. Group A consisted of 6 patients of cholangiocarcinoma who underwent hepatic arterial infusion chemotherapy associated with radiotherapy. Groups B and C consisted of 8 and 6 patients of stage IVa and IVb pancreatic carcinoma, respectively, who underwent hepatic and splenic arterial infusion chemotherapy following transcatheter peripancreatic arterial embolization. The 50% patent time was 12 months, 6 months and 7 months in groups A, B and C and the 50% overall survival time was 16 months, 23 months and 13 months, respectively. There were two complications, 1 case of infection around the IP in which the IP was withdrawn, and 3 cases of cholangitis in which we had easy access to the bile duct via IP. This technique appears to offer significant benefit in selecting patients with this type of biliary obstruction. 相似文献

Colonic stents potentially offer effective palliation for patients with bowel obstruction attributable to incurable malignancy, and a "bridge to surgery" for those in whom emergency surgery would necessitate a stoma. Literature search of the Medline, Scopus and Cochrane Library was performed to identify comparative studies reporting outcomes on colonic stenting and surgery for large bowel obstruction; and to identify the use of stents as a "bridge to the elective surgery". Colorectal stenting can be considered a safe and effective procedure with a low mortality and morbidity for both preoperative and palliative decompression of colonic obstruction. 相似文献

Airway stenting is required for the palliative treatment of advanced esophageal cancer. This study retrospectively analyzes the outcomes of airway stenting for esophageal cancer at our institution. Data from nine patients who underwent airway stenting were reviewed. All patients had poor respiratory status due to esophagorespiratory fistula and/or respiratory stenosis. We retrospectively assessed the results of airway stenting as five grades of respiratory symptoms, regarding stent-related complications and clinical course and survival. Six silicone and six covered self-expandable metallic stents were deployed in five and six patients, respectively. Two types of airway stents were deployed in two patients, and double stents were positioned in the airway and in the esophagus of three other patients. The grade of respiratory symptoms improved in seven patients. The mean dyspnea grade was 3.0±0.9 and 1.3±1.3 before and after airway stenting, respectively. Stent-related complications comprised of chest pain, incomplete closure of the ERF, sputum retention and stent migration. The mean±SD survival of all patients was 103±108 (range, 0 to 325) days, and the survival of patients without relapsed cancer at the time of stenting, who underwent cancer-specific therapy after stenting, was prolonged. Although the airway should be stented according to the status and the prognosis of each patient individually stenting can relieve symptoms and improve the prognosis even when esophageal cancer is at very advanced stages. Airway stenting could play a role in the multidisciplinary management of advanced esophageal cancer. 相似文献

When percutaneous transhepatic biliary drainage (PTBD) is required for the management of malignant biliary obstruction, the local policy favours the use of internal–external drains. Regular planned drain exchanges are scheduled, and patients have open access back into the system to minimise complications. The aim of this study was to evaluate the success and complication rate of this method for the palliation of malignant biliary obstruction. The hospital records of 43 consecutive patients who underwent PTBD for malignant biliary obstruction at a single institution between 1 February 2004 and 31 January 2006 were reviewed. Outcomes were examined until January 2008. Biliary decompression was achieved in all 43 patients. The level of obstruction was defined as distal in 24 patients and perihilar in 19 patients. There was one procedure-related death. There were 91 routine outpatient drain exchanges performed at a median interval of 45 (range 21–64) days. Overall, 24/43 patients encountered 80 discrete complications related to biliary drainage. Fifty-two non-scheduled drain exchanges (accounting for 65% of all complications) were performed on an outpatient basis. Fourteen patients were readmitted on a median of one (range 1–3) occasion for a median duration of 3 (range 1–12) days. Median survival was 71 (range 7–850) days. PTBD can be performed with low mortality, but long-term morbidity remains high despite an aggressive approach to maintaining biliary patency. Providing patients with an open-access service means the majority of complications can be dealt with on an outpatient basis. 相似文献

Systemic therapy for biliary tract cancers 总被引:2,自引:0,他引:2
Biliary tract cancers (BTCs) are invasive carcinomas that arise from the epithelial lining of the gallbladder and bile ducts. These include intrahepatic, perihilar, and distal biliary tree cancers as well as carcinoma arising from the gallbladder. Complete surgical resection offers the only chance for cure; however, only 10% of patients present with early-stage disease and are considered surgical candidates. Among those patients who do undergo "curative" resection, recurrence rates are high; thus, for the majority of BTC patients, systemic chemotherapy is the mainstay of their treatment plan. Patients with unresectable or metastatic BTC have a poor prognosis, with a median overall survival time of <1 year. Despite a paucity of randomized phase III data, a consensus on first-line systemic therapy is emerging. In this review, we discuss the clinical experience with systemic treatment of BTC, focusing on the rationale for a first-line regimen as well as future directions in the field. 相似文献

Malignant biliary strictures often present late after the window for curative resection has elapsed. In such patients, the goal of therapy is typically focused on palliation. While historically, palliative measures were performed surgically, the advent of endoscopic intervention offers minimally invasive options to provide relief of symptoms, improve quality of life, and in some cases, increase survival of these patients. Some of these therapies, such as endoscopic biliary decompression, have become mainstays of treatment for decades, whereas newer modalities, including radiofrequency ablation, and photodynamic therapy offer additional options for patients with incurable biliary malignancies. 相似文献
