为探讨内镜下胆管支架置入后行光动力治疗(photodynamic therapy,PDT)和(或)射频消融术(radiofrequency ablation,RFA)在不可切除肝外胆管癌(extrahepatic cholangiocarcinoma,EHCC)姑息治疗中的应用,回顾性分析了2017年1月至2023年1月在青岛大学附属医院消化内科治疗的5例EHCC患者的临床资料。5例患者均先接受胆管支架置入治疗,支架置入后6个月内接受PDT和(或)RFA。5例患者手术均成功。治疗后,5例患者血清胆红素水平均明显下降,术后恢复良好,1~3 d即好转出院。1例患者出现感染性并发症,其余均未发生不良事件。胆管支架治疗先于PDT和(或)RFA对EHCC进行姑息治疗,为后续PDT和(或)RFA顺利进行创造良好条件,可明显提高手术成功率,快速有效解除管腔梗阻,减少术后不良事件的发生,缩短术后恢复时间。 相似文献

AIM: To determine the impact(morbidity/mortality) of biliary stent-related events(SRE)(cholangitis or stent obstruction) in chemotherapy-treated pancreaticobiliary patients.METHODS: All consecutive patients with advanced pancreatobiliary cancer and a biliary stent in-situ prior to starting palliative chemotherapy were identified retrospectively from local electronic case-note records(Jan 13 to Jan 15). The primary end-point was SRE rate and the time-to-SRE(defined as time from first stenting before chemotherapy to date of SRE). Progressionfree survival and overall survival were measured from the time of starting chemotherapy. Kaplan-Meier, Cox and Fine-Gray regression(univariate and multivariable) analyses were employed, as appropriate. For the analysis of time-to-SRE, death was considered as a competing event.RESULTS: Ninety-six out of 693 screened patients were eligible; 89% had a metal stent(the remainder were plastic). The median time of follow-up was 9.6 mo(range 2.2 to 26.4). Forty-one patients(43%)developed a SRE during follow-up [cholangitis(39%), stent obstruction(29%), both(32%)]. There were no significant differences in baseline characteristics between the SRE group and no-SRE groups. Recorded SRE-consequences were: none(37%), chemotherapy delay(24%), discontinuation(17%) and death(22%). The median time-to-SRE was 4.4 mo(95%CI: 3.6-5.5). Patients with severe comorbidities(P 0.001) and patients with ≥ 2 baseline stents/biliary procedures [HR = 2.3(95%CI: 1.2-4.44), P = 0.010] had a shorter time-to-SRE on multivariable analysis. Stage was an independent prognostic factor for overall survival(P = 0.029) in the multivariable analysis adjusted for primary tumour site, performance status and development of SRE(SRE group vs no-SRE group).CONCLUSION: SREs are common and impact on patient's morbidity. Our results highlight the need for prospective studies exploring the role of prophylactic strategies to prevent/delay SREs. 相似文献

Most patients with pancreatic cancer develop malignant biliary obstruction. Treatment of obstruction is generally indicated to relieve symptoms and improve morbidity and mortality. First-line therapy consists of endoscopic biliary stent placement. Recent data comparing plastic stents to self-expanding metallic stents (SEMS) has shown improved patency with SEMS. The decision of whether to treat obstruction and the means for doing so depends on the clinical scenario. For patients with resectable disease, preoperative biliary decompression is only indicated when surgery will be delayed or complications of jaundice exist. For patients with locally advanced disease, self-expanding metal stents are superior to plastic stents for long-term patency. For patients with advanced disease, the choice of metallic or plastic stent depends on life expectancy. When endoscopic stent placement fails, percutaneous or surgical treatments are appropriate. Endoscopic therapy or surgical approach can be used to treat concomitant duodenal and biliary obstruction. 相似文献

Pancreatic ductal adenocarcinoma(PDAC) and cholangiocarcinoma(CCA) are two malignancies that carry significant morbidity and mortality. The poor prognoses of these cancers are strongly related to lack of effective screening modalities as well as few therapeutic options. In this review, we highlight novel biomarkers that have the potential to be used as diagnostic, prognostic and predictive markers. The focus of this review is biomarkers that can be evaluated on endoscopically-obtained biopsies or brush specimens in the pre-operative setting. We also provide an overview of novel serum based markers in the early diagnosis of both PDAC and CCA. In pancreatic cancer, the emphasis is placed on prognostic and theranostic markers, whereas in CCA the utility of molecular markers in diagnosis and prognosis are highlighted. 相似文献

Background: Occlusion of self-expanding metal stents(SEMS) in malignant biliary obstruction occurs in up to 40% of patients. This study aimed to compare the different techniques to resolve stent occlusion in our collective of patients.Methods: Patients with malignant biliary obstruction and occlusion of biliary metal stent at a tertiary referral endoscopic center were retrospectively identified between April 1, 1994 and May 31, 2014. The clinical records were further analyzed regarding the characteristics of patients, malignant strictures, SEMS,management strategies, stent patency, subsequent interventions, survival time and case charges.Results: A total of 108 patients with biliary metal stent occlusion were identified. Seventy-nine of these patients were eligible for further analysis. Favored management was plastic stent insertion in 73.4% patients. Second SEMS were inserted in 12.7% patients. Percutaneous transhepatic biliary drainage and mechanical cleansing were conducted in a minority of patients. Further analysis showed no statistically significant difference in median overall secondary stent patency(88 vs. 143 days, P = 0.069), median survival time(95 vs. 192 days, P = 0.116), median subsequent intervention rate(53.4% vs. 40.0%, P = 0.501)and median case charge(€5145 vs. €3473, P = 0.803) for the treatment with a second metal stent insertion compared to plastic stent insertion. In patients with survival time of more than three months,significantly more patients treated with plastic stents needed re-interventions than patients treated with second SEMS(93.3% vs. 57.1%, P = 0.037).Conclusions: In malignant biliary strictures, both plastic and metal stent insertions are feasible strategies for the treatment of occluded SEMS. Our data suggest that in palliative biliary stenting, patients especially those with longer expected survival might benefit from second SEMS insertion. Careful patient selection is important to ensure a proper decision for either management strategy. 相似文献
