Placement of endoscopic naso-biliary drainage does not preclude subsequent percutaneous transhepatic biliary drainage

We prospectively investigated whether the placement of endoscopic naso-biliary drainage (ENBD) precluded percutaneous transhepatic biliary drainage (PTBD). In 40 patients, the caliber of the intrahepatic bile duct was measured prior to ENBD by ultrasonography. When PTBD was required after ENBD, the ENBD catheter was clamped for 1 to 2 h before PTBD, and its caliber was again measured at the time of PTBD. When PTBD was performed within 7 days (mean, 1.8 days) after ENBD (n = 27), the size of the intrahepatic bile duct was 5.0 ± 2.3 mm before and 4.6 ± 2.3 mm after ENBD. There was no significant difference between these values (P > 0.5). When PTBD was performed 8 to 40 days (mean, 17.8 days) after ENBD (n = 13), the bile duct diameter was significantly reduced, from 4.2 ± 1.5 mm (pre-ENBD) to 1.8 ± 1.7 mm (post-ENBD) (P < 0.05). When PTBD was conducted within 7 days (mean, 1.8 days) after ENBD, previous ENBD did not induce collapse of the bile duct, if the ENBD catheter was clamped for 1 to 2 h before the puncture of the bile duct.

Peripheral portal vein-oriented non-dilated bile duct puncture for percutaneous transhepatic biliary drainage

AIM: To evaluate the efficacy of peripheral portal vein(PV)-oriented non-dilated bile duct(BD) puncture for percutaneous transhepatic biliary drainage(PTBD).METHODS: Thirty-five patients with non-dilated BDs underwent PTBD for the management of various biliary disorders, including benign bilioenteric anastomotic stricture(n = 24), BD stricture(n = 5) associated with iatrogenic BD injury, and postoperative biliary leakage(n = 6). Under ultrasonographic guidance, percutaneous transhepatic puncture using a 21-G needle was performed along the running course of the peripheral targeted non-dilated BD(preferably B6 for right-sided approach, and B3 for left-sided approach) or along the accompanying PV when the BD was not well visualized. This technique could provide an appropriate insertion angle of less than 30° between the puncture needle and BD running course. The puncture needle was then advanced slightly beyond the accompanying PV. The needle tip was moved slightly backward while injecting a small amount of contrast agent to obtain the BD image, followed by insertion of a 0.018-inch guide wire(GW). A drainage catheter was then placed usinga two-step GW method. RESULTS: PTBD was successful in 33(94.3%) of the 35 patients with non-dilated intrahepatic BDs. A rightsided approach was performed in 25 cases, while a left-sided approach was performed in 10 cases. In 31 patients, the first PTBD attempt proved successful. Four cases required a second attempt a few days later to place a drainage catheter. PTBD was successful in two cases, but the second attempt also failed in the other two cases, probably due to poor breath-holding ability. Although most patients(n = 26) had been experiencing cholangitis with fever(including septic condition in 8 cases) before PTBD, only 5(14.3%) patients encountered PTBD procedure-related complications, such as transient hemobilia and cholangitis. No major complications such as bilioarterial fistula or portal thrombosis were observed. There was no mortality in our series.CONCLUSION: Peripheral PV-oriented BD puncture for PTBD in patients with non-dilated BDs is a safe and effective procedure for BD stricture and postoperative bile leakage.

Combined percutaneous transhepatic biliary drainage with port implantation for management of patients with malignant biliary obstruction

BACKGROUND: Endoscopic biliary stent insertion has become a standard palliative treatment for patients with obstructive jaundice caused by malignancies of the hepatobiliary system or metastases of other tumors, such as pancreatic or gastric cancer. Unfortunately, bacterial colonization and encrustation frequently leads to occlusion of plastic stents and, consequently, recurrent cholangitis. METHODS: An external-internal Yamakawa-type endoprosthesis was modified and combined with a titanium, subcutaneously implanted port. This technique was evaluated as a new approach to prolongation of stent patency and prevention of cholangitis. Two patients with obstructive jaundice, one with recurrent gastric carcinoma and the other with invasive gallbladder cancer, underwent treatment with this new method. RESULTS: Effective biliary drainage was established and cholangitis was prevented in both patients for 6 and 2 months, respectively. CONCLUSIONS: A new method of percutaneous transhepatic drainage combined with port implantation was effective and safe in two patients. This technique may be a reasonable treatment option for selected patients, but further evaluation in a larger series is required to establish efficacy and safety.     

Current status of preoperative drainage for distal biliary obstruction

Preoperative biliary drainage (PBD) was developed to improve obstructive jaundice, which affects a number of organs and physiological mechanisms in patients waiting for surgery. However, its role in patients who will undergo pancreaticoduodenectomy for biliary obstruction remains controversial. This article aims to review the current status of the use of preoperative drainage for distal biliary obstruction. Relevant articles published from 1980 to 2015 were identified by searching MEDLINE and PubMed using the keywords “PBD”, “pancreaticoduodenectomy”, and “obstructive jaundice”. Additional papers were identified by a manual search of the references from key articles. Current studies have demonstrated that PBD should not be routinely performed because of the postoperative complications. PBD should only be considered in carefully selected patients, particularly in cases where surgery had to be delayed. PBD may be needed in patients with severe jaundice, concomitant cholangitis, or severe malnutrition. The optimal method of biliary drainage has yet to be confirmed. PBD should be performed by endoscopic routes rather than by percutaneous routes to avoid metastatic tumor seeding. Endoscopic stenting or nasobiliary drainage can be selected. Although more expensive, the use of metallic stents remains a viable option to achieve effective drainage without cholangitis and reintervention.     

Percutaneous transhepatic biliary drainage in patients with malignant biliary obstruction of the hepatic confluence.

Despite many studies on percutaneous transhepatic biliary drainage (PTBD), there are no satisfactory reports of PTBD for malignant obstruction of the hepatic confluence. In this study, the results of PTBD using the direct anterior approach under fluoroscopic guidance are described in 16 patients with malignant biliary obstruction of the hepatic confluence. A total of forty-two drainage catheters were placed in the 16 patients: one catheter was placed in three patients; two catheters in six; three catheters in four; four catheters in two; seven catheters in one. PTBD was successful in 100% of the cases with no mortality or critical complications, and the biliary decompression effect of PTBD was highly satisfactory. Nine patients underwent histologically curative hepatectomies. Two of the nine resected cases died of postoperative hepatic failure, but the postoperative course in the others was satisfactory. The authors stress that selective biliary drainage for each isolated segmental duct is mandatory for advanced malignant obstruction of the hepatic confluence.

Optimization of biliary drainage in inoperable distal malignant strictures

BACKGROUND Given most patients with distal malignant biliary obstruction present in the nonresectable stage, palliative endoscopic biliary drainage with fully covered metal stent(FCMS) or uncovered metal stent(UCMS) is the only available measure to improve patients' quality of life. Half covered metal stent(HCMS) has been recently introduced commercially. The adverse effects and stent function between FCMS and UCMS have been extensively discussed.AIM To study the duration of stent patency of HCMS and compare it with FCMS and UCMS to optimize biliary drainage in inoperable patients with distal malignant obstruction. Secondary aims in our study included evaluation of patients' survival and the rates of adverse events for each type of stent.METHODS We studied 210 patients and randomized them into three equal groups; HCMS, FCMS and UCMS were inserted endoscopically.RESULTS Stent occlusion occurred in(18.6%, 17.1% and 15.7% in HCMS, FCMS and UCMS groups, respectively, P = 0.9). Stent migration occurred only in patients with FCMS(8.6% of patients). Cholangitis and cholecystitis occurred in 11.4% and 5.7% of patients, respectively, in FCMS. Tumor growth occurred only in 10 cases among patients with UCMS after a median of 140 d, sludge occurred in nine, seven and one patients in HCMS, FCMS and UCMS, respectively(P = 0.04).CONCLUSION Given the prolonged stent functioning time, the use of HCMS is preferred over the use of UCMS and FCMS for optimizing biliary drainage in patients with distal malignant biliary obstruction.     

Effect of biliary obstruction and internal biliary drainage on hepatic cytochrome P450 isozymes in rats

AIM： To investigate the total cytochrome P450 （CYP） content, microsomal mixed-function oxidase （MFO） activity, and expression of mRNAs for various CYP isozymes in a simple rat model of reversible obstructive jaundice. METHODS： Obstructive jaundice was created in male rats by causing bile duct obstruction with polyester tape. In another group of rats, bile duct obstruction was followed by internal biliary drainage after releasing the tape. The expression of various CYP isozyme mRNAs was semi-quantitatively assessed by competitive RT- PCR. RESULTS： The total CYP content and microsomal MFO activity showed a significant decrease after biliary obstruction, but returned to respective control levels after biliary drainage. A marked reduction in the expression of CYP1A2, 2B1/2, 2C11, 2E1, 3A1, and 3A2 mRNA was detected during biliary obstruction, while expression increased significantly toward the control level after biliary drainage. Although expression of CYP4A1 mRNA showed no reduction during biliary obstruction, it still increased significantly after biliary drainage. CONCLUSION： These results suggest that not only obstructive jaundice, but also the subsequent internal biliary drainage may affect regulatory medications of the synthesis of individual CYP isozymes differently.     

Change in serum and biliary esterified bile acids in patients with extrahepatic cholestasis during percutaneous transhepatic cholangiodrainage

Eighteen patients with total extrahepatic cholestasis undergoing PTCD were classified into three groups, depending on the bilirubin decrease rate at two weeks after PTCD. Serum and biliary esterified bile acids in each group were measured before PTCD and at 24 hours, 48 hours, 1 week, and 2 weeks after PTCD. Bile acids were measured by Okuyama’s methods (HPLC), and esterified bile acids were calculated from the difference between samples treated with sulfatase or β-glucuronidase for enzymatic hydrolysis and untreated samples measured at the same time. The following results were obtained. The percentages of biliary esterified bile acids in total bile acids were as follows: before PTCD, in the fair improvement group, sulfate (S) = 6.4 ± 4.6 % (mean ± S.D.), glucuronide (G) = 11.7 ± 9.0 % ; in the poor improvement group, S = 2.8 ± 1.6 %, G = 1.0 ± 0.9 % and at 24 hours after PTCD, in the fair group, S = 9.1 ± 7.5 %, G = 7.5 ± 4.3 % ; in the poor group, S = 2.9 ± 2.4 %, G =1.7 ± 1.1 %. The percentages of esterified bile acids in the fair group were higher than in the poor group, and significant differences were noted in G (p<0.05). Thus PTCD is expected to reduce jaundice in cases with high percentages of biliary esterified bile acids before and shortly after PTCD.     

导丝引导法经皮经肝胆管穿刺引流术的临床应用

目的 采用改良步骤进行经皮经肝胆管穿刺引流术（PTBD）,与常规PTBD方法对比,期待减少PTBD相关胆管炎发生率。方法 回顾性分析2011年1月至2017年12月因胆道疾病在我院行PTBD治疗的174例患者资料,其中85例为常规步骤操作（常规组）,89例在胆管穿刺成功后不注入造影剂,先借助导丝引导穿刺针外套管进入胆管深部,抽取胆汁充分减压后再造影（导丝引导组）,比较两种方法的成功率及术后PTBD相关胆管炎发生率。结果 导丝引导组与常规组比较,置管成功率比较差异无统计学意义[94.4%（84/89）比97.6%（83/85）,?2=1.200,P=0.273],但PTBD相关胆管炎发生率低于后者[10.1%（9/89）比21.2%（18/85）,?2=5.270,P=0.022]。结论 导丝引导法PTBD与常规方法PTBD比较,操作成功率相当,但可降低术后胆管炎发生率。     

Technical tips and troubleshooting of endoscopic biliary drainage for unresectable malignant hilar biliary obstruction

Unresectable malignant hilar biliary obstruction (MHBO) occurs in various diseases, such as cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, pancreatic cancer, and lymph node metastasis of the hilum of the liver. The majority of patients with advanced MHBO are not candidates for surgical resection because of the tumor location in the hepatic hilum and adjacent areas, advanced tumor stage, or comorbidities. Therefore, these patients often have a poor prognosis in terms of survival and quality of life. Most of these patients will require non‐surgical, palliative biliary drainage. To date, various biliary drainage techniques for unresectable MHBO (UMHBO) have been reported. Of these techniques, endoscopic biliary drainage is currently considered to be the most safe and minimally invasive procedure. However, endoscopic biliary drainage for UMHBO is still not standardized regarding the optimal stent, drainage area, stenting method, and reintervention technique. Recently, towards standardization of this technique for UMHBO, clinical research and trials including randomized controlled trials have been performed. In this article, we reviewed the most important issues regarding endoscopic biliary drainage for UMHBO, focusing on prospective studies. We also described in detail the techniques and future perspectives of endoscopic biliary drainage in patients with UMHBO.
