Percutaneous transhepatic biliary drainage (PTBD) is a method of biliary tree decompression, applied as palliative treatment in patients with malignant biliary tree critical stenosis/obstruction, but also as a potentially curative treatment in patients with non-malignant biliary tree stenosis. Novel instrumentation dedicated to PTBD has been designed in recent years, which makes it possible to perform more advanced procedures in patients with severe extensive malignant biliary tree stenosis/obstruction.
The first primary goal of the study was to compare both the rate and types of short- and long-term complications in patients who had undergone PTBD between 2000 and 2006 with patients treated between 2007 and 2011. The second primary goal of the study was to work out an original algorithm of efficient management in patients undergoing PTBD. An additional goal was to assess the efficacy of PTBD and the overall survival of the patients.
One-hundred twenty-eight consecutive PTBD procedures performed between 2000 and 2006 in patients with malignant biliary jaundice were analyzed retrospectively. Similarly, retrospective analysis of 73 consecutive procedures in patients with malignant biliary jaundice performed between 2007 and 2011 was carried out. Subsequently, the results of both subsets were compared to each other. The PTBD procedure was guided fluoroscopy each time. PTBD involved external biliary drainage and/or stenting of the strictured/occluded segments of extra- and intrahepatic biliary ducts.
The analysis demonstrated a statistically significant decrease in the overall incidence of short- and long-term complications in patients undergoing PTBD in 2007-2011 in comparison to the subset treated in 2000-2006. Among the early complications, a significant decrease in sub- and pericapsular contrasted bile leaks was shown. The evaluation of long-term complications demonstrated lower incidence of the falling out of the draining catheter. The implementation of novel instrumentation made it possible to perform biliary stenting in 63.7% cases of common bile duct (CBD) obstruction (vs. 37.5% in procedures carried out in 2000-2006). However, no statistically significant difference in survival between the two analyzed subsets was demonstrated.
The analysis of rate and types of complications made it possible to establish authors own algorithm of management in different types of biliary obstructions and strictures. The modification of procedure technique, pos-tinterventional management and usage of the new generation of low-profile instrumentation for percutaneous access dedicated to PTBD has resulted in a significant reduction of the complication rate in the last 5 years. Higher frequency of CBD stenting improves the quality of life in this subset of patients.
经皮经肝胆道引流术(PTBD)是一种胆道减压方法,适用于恶性胆道严重狭窄/梗阻的姑息治疗,但也可作为非恶性胆道狭窄的潜在治愈性治疗。近年来,专门用于 PTBD 的新型仪器已经设计出来,这使得在严重广泛的恶性胆道狭窄/梗阻患者中进行更先进的治疗成为可能。
该研究的首要目标是比较 2000 年至 2006 年和 2007 年至 2011 年接受 PTBD 的患者的短期和长期并发症的发生率和类型。该研究的第二个首要目标是制定一种针对接受 PTBD 患者的有效管理的原始算法。此外,还评估了 PTBD 的疗效和患者的总生存率。
回顾性分析了 2000 年至 2006 年间 128 例恶性胆道阻塞患者的连续 128 例 PTBD 手术,以及 2007 年至 2011 年间 73 例恶性胆道阻塞患者的连续 73 例 PTBD 手术。随后,将这两个亚组的结果相互比较。每次 PTBD 手术都在透视引导下进行。PTBD 包括外部胆道引流和/或支架置入扩张/阻塞的肝内外胆管。
分析表明,与 2000-2006 年治疗的患者相比,2007-2011 年接受 PTBD 的患者的短期和长期并发症总发生率显著降低。在早期并发症中,明显减少了亚囊和囊下对比胆汁漏。长期并发症的评估显示,引流管脱落的发生率较低。新型仪器的应用使得胆总管(CBD)阻塞的 63.7%(2000-2006 年治疗的 37.5%)患者可以进行胆道支架置入。然而,在这两个分析亚组之间没有显示出统计学上的生存差异。
对并发症发生率和类型的分析使我们能够建立作者自己的管理算法,用于不同类型的胆道阻塞和狭窄。手术技术的改进、术后管理和新型专用经皮穿刺通道的新一代低轮廓仪器的使用,使过去 5 年的并发症发生率显著降低。更高频率的 CBD 支架置入改善了这组患者的生活质量。
