经肝动脉化疗栓塞联合经皮射频消融术治疗原发性肝癌的疗效观察

【摘要】 目的 探讨经肝动脉化疗栓塞（TACE）联合经皮射频消融术（PRFA）与单独应用经皮射频消融术治疗原发性肝癌的临床疗效。方法 选择2012年3月～2014年3月在我院诊治的肝癌患者90例,随机分为观察组（50例）与对照组（40例）。观察组予以经肝动脉化疗栓塞联合经皮射频消融术,对照组应用经皮射频消融术治疗,观察两组疗效及预后情况。结果 术后1个月两组患者并发症如疼痛、肺部感染、出血、恶心呕吐等发生率差异无统计学意义（P＞0.05）;两组术后1个月时血清丙氨酸氨基转移酶（ALT）与门冬氨酸氨基转移酶（AST）水平均低于术前(P＜0.05),但观察组术后一个月血清ALT和AST值显著低于对照组(P＜0.05);观察组与对照组比较能明显提高近期有效率(P＜0.05)。结论 两种治疗方案均能有效治疗原发性肝癌,但经肝动脉化疗栓塞联合经皮射融术相对于单独应用经皮射频消融术,在原发性肝癌治疗中具有更高的缓解率,更有利于肝功能的恢复,可减少术后并发症。

Management of low-grade dysplasia in Barrett’s esophagus: Ablate or survey?

There are several issues that continue to make the management of Barrett’s esophagus and low-grade dysplasia challenging especially in terms of determining the optimal management strategy—surveillance vs endoscopic eradication therapy (EET). Some of these include a highly variable rate of neoplastic progression to high-grade dysplasia or cancer and significant interobserver variability among pathologists (including expert gastrointestinal pathologists). The efficacy and effectiveness of EET, predominantly using radiofrequency ablation, in reducing the risk of progression has been well described. However, there are limited data that define the ideal candidates most likely to benefit from EET compared with surveillance. This review discusses the challenges in the diagnosis and management of Barrett’s esophagus with low-grade dysplasia, provides practice advice for this patient population and the need for physicians to incorporate quality indicators in clinical practice.     

Stereotactic Excision of Additional Lesions Detected with Intraoperative Ultrasound Examination During Radiofrequency Dissecting Sealar (Habib®) Assisted Hepatic Metastasectomy: Report of 4 Cases

Intraoperative ultrasound has been using to achieve a proper resection strategy in patients undergoing a hepatic colorectal metastasectomy. This study aims to describe and reveal the place of stereotactic metastasectomy in nonpalpable colorectal liver metastases (CLM). A chart review was initiated for all patients underwent resection for CLM between 2006 and 2011. The data concerning perioperative data and intraoperative strategy were abstracted. Among the 58 patients, who underwent a resection for CLM, 4 (6.9 %) (all men, median age 65.5, range 49–72, years) necessitated a stereotactic metastasectomy. Preoperative evaluations showed 1 (n = 1), 2 (n = 2), or 3 (n = 1) lesions, and intraoperative ultrasound (IUS) found an additional lesion in a case. Stereotactic marking was performed for nonpalpable lesions located in segments IVA, II, and VI and at the junction of segments V and VI. The margins were negative for all lesions both resected with conventional and stereotactic techniques. The examinations of the stereotactic resection materials revealed metastatic adenocarcinoma (patients n = 2), focal nodular hyperplasia (n = 1), and abnormal benign liver histology probably induced by chemotherapy (n = 1). The median (range) operation and hospitalization periods were 217.5 (150–310) minutes and 5.5 (2–9) days. No complications were observed except biliary fistula in a case, which spontaneously disappeared within 2 weeks. A patient died due to systemic disease including hepatic metastases 33 months after the liver surgery. Stereotactic metastasectomy may be feasible for the removal of nonpalpable CLM. Further evaluations are necessitated to understand the accurate place of this novel technique.
