Abstract

Background

While hilar cholangiocarcinoma (HCCA) patients commonly undergo radioactive stent (RS) insertion treatment, the relative benefits of unilateral versus bilateral RS insertion procedures remain to be established. Accordingly, this study was designed to evaluate the relative safety and efficacy of percutaneous bilateral and unilateral RS insertion for patients with HCCA.

Methods

In total, 126 HCCA patients who underwent unilateral (n=64) or bilateral (n=62) RS insertion from January 2017 - December 2021 were included in this analysis. Treatment efficacy and long-term outcomes were compared between groups. The primary endpoint was stent patency, and the secondary endpoints included technical success rate, clinical success rate, local control rate, overall survival (OS), and complications.

Results

The respective technical success rates in the unilateral and bilateral groups were 90.6% (58/64) and 93.5% (58/62) (P = 0.782). The clinical success rates were 82.8% and 86.2% in unilateral and bilateral groups, respectively (P = 0.608). Both groups exhibited comparable medial post-intervention bilirubin levels (100 vs. 99 μmol/L; P = 0.501), and restenosis occurred in 12 (20.7%) and 15 (25.9%) patients over the follow-up interval (P = 0.510). The stent reintervention rate was significantly higher in the unilateral group than bilateral group (66.7% vs. 0.0%, P < 0.001). The median stent patency in the unilateral and bilateral groups was 189 and 210 days, respectively (P = 0.796), while the median OS interval was 222 and 229 days, respectively (P = 0.969). Comparable cholangitis (17.2% vs. 22.4%, P = 0.485) and cholecystitis (3.4% vs. 3.4%, P = 1.000) rates were also detected in these two groups.

Conclusions

In summary, HCCA patients exhibit comparable efficacy when undergoing unilateral and bilateral radioactive stenting, suggesting that unilateral RS can be routinely performed owing to the simpler nature of this procedure.

Abstract

OBJECTIVES

Malignant biliary stricture is a ductal narrowing of the bile duct that is often diagnosed at an advanced stage, leading to difficulty in resection. The current study aims to evaluate the feasibility of endobiliary laser treatment by quantifying the extent of coagulative necrosis in tissue under various conditions.

METHODS

Ex vivo and in vivo porcine bile tissues were used for endobiliary laser treatment to characterize the dosimetric responses of the tissue to various treatment conditions: power level, irradiation time, and number of treatments. 532 nm laser light was coupled with a balloon-integrated diffusing applicator (BDA) to deliver the laser light endoscopically for tissue coagulation. The coagulated regions (maximum length and depth) in the treated tissues were evaluated histologically for quantitative comparison.

RESULTS

Dosimetric evaluations with ex vivo liver tissue confirmed that both maximum length and depth of coagulative necrosis (CN) increased with applied power and number of treatments. Ex vivo bile duct tests demonstrated that BDA-assisted laser treatment at 10 W for 12 s reproducibly yielded CN with a length of 5.8 ± 1.6 mm and a depth of 0.6 ± 0.2 mm. In vivo tests presented that endoscopic laser treatment using the BDA created CN on the ductal surface without any perforation. Microscopic examinations revealed that a dense inflammatory cell infiltration and eosinophilic area in the in vivo treated tissue. The extent of CN in the in vivo tissue was 40% longer and 120% deeper (length: 8.1 ± 0.7 mm; depth: 1.3 ± 0.2 mm), compared to that in the ex vivo tissue.

CONCLUSION

BDA-assisted laser treatment could be a feasible option for endoscopic treatment of biliary stricture with uniform ablation at the circumference of bile duct. Further in vivo studies will be performed in a large number of stricture-developed porcine models to examine both efficacy and safety of the proposed endobiliary laser treatment for clinical translations.

Endoscopic Biliary Darinage (EBD) versus Percutaneous Transhepatic Biliary Drainage (PTBD) for biliary drainage in patients with Perihilar Cholangiocarcinoma (PCCA): A systematic review and meta-analysis. Clinics (Sao Paulo) 2023;78:100163. [PMID: 36681067 PMCID: PMC10757298 DOI: 10.1016/j.clinsp.2022.100163] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 11/27/2022] [Accepted: 12/19/2022] [Indexed: 01/21/2023] Open

Abstract

Biliary drainage for Perihilar Cholangiocarcinoma (PCCA) can be performed either by endoscopic retrograde cholangiopancreatography or Percutaneous Transhepatic Biliary Drainage (PTBD). To date there is no consensus about which method is preferred. Taking that into account, the aim of this study is to compare Endoscopic Biliary Drainage (EBD) versus percutaneous transhepatic biliary drainage in patients with perihilar cholangiocarcinoma through a systematic review and metanalysis. A comprehensive search of multiple electronic databases was performed. Evaluated outcomes included technical success, clinical success, post drainage complications (cholangitis, pancreatitis, bleeding, and major complications), crossover, hospital length stay, and seeding metastases. Data extracted from the studies were used to calculate Mean Differences (MD). Seventeen studies were included, with a total of 2284 patients (EBD = 1239, PTBD = 1045). Considering resectable PCCA, the PTBD group demonstrated lower rates of crossover (RD = 0.29; 95% CI 0.07‒0.51; p = 0.009 I² = 90%), post-drainage complications (RD = 0.20; 95% CI 0.06‒0.33; p < 0.0001; I² = 78%), and post-drainage pancreatitis (RD = 0.10; 95% CI 0.05‒0.16; p < 0.0001; I² = 64%). The EBD group presented reduced length of hospital stay (RD = -2.89; 95% CI -3.35 ‒ -2,43; p < 0.00001; I² = 42%). Considering palliative PCCA, the PTBD group demonstrated a higher clinical success (RD = -0.19; 95% CI -0.27 ‒ -0.11; p < 0.00001; I² = 0%) and less post-drainage cholangitis (RD = 0.08; 95% CI 0.01‒0.15; p = 0.02; I² = 48%) when compared to the EBD group. There was no statistical difference between the groups regarding: technical success, post-drainage bleeding, major post-drainage complications, and seeding metastases.

Abstract

Purpose

To assess the association between sarcopenia and the risk of early biliary infection (EBI) after percutaneous transhepatic biliary stent (PTBS) placement in patients with inoperable biliary tract cancer (BTC).

Patients and methods

In this single center, retrospective observational study, patients diagnosed with inoperable BTC undergoing PTBS placement between January 2013 and July 2021 were enrolled. Preoperative sarcopenia was defined based on skeletal muscle mass measured by computed tomography images on the level of third lumbar vertebra within one month before PTBS placement. Patients were divided into two groups in accordance with the status of sarcopenia. Univariate and further multivariate logistic analyses were performed to determine predictors for EBI. Stratified and interactive analyses were conducted to investigate the stability of results. Further receiver operating characteristic curve was performed to determine the predictive value of sarcopenia on EBI after PTBS placement.

Results

Totally, 134 patients were included in this retrospective study, with 45 (33.6%) patients characterized as sarcopenia. The incidence rate of EBI was 26.9% (36/134). Multivariate analyses demonstrated that sarcopenia [Odds ratio (OR), 2.75; 95%CI: 1.11-6.77; P=0.028], obstruction length (OR, 1.04; 95%CI: 1.00-1.08; P=0.030) and diabetes (OR, 2.46; 95%CI: 1.01-5.96; P=0.047) were significant predictors of EBI. There were no significant interactions in different subgroups (P for interaction > 0.05). Moreover, the areas under the curves (AUC) revealed that the combined index containing sarcopenia, obstruction length, and diabetes showed the better predictive value (AUC= 0.723) than either one alone.

Conclusion

Sarcopenia increased the risk of EBI in patients with inoperable BTC after PTBS placement. Preoperative assessment of sarcopenia may aid in risk stratification. Patients with sarcopenia should be given intensive monitoring.

Abstract

BACKGROUND

In the case of an unresectable malignant hilar biliary obstruction (MHBO), the optimal drainage method has not yet been established. Recently, an 8 mm, fully covered, self-expandable metal stent (FCSEMS) with an ultra-slim introducer has become available. In this article, the results of whole-liver drainage tests using this novel FCSEMS for MHBO are reported.

METHODS

Unresectable MHBOs up to Bismuth IIIa with strictures limited to the secondary branches were eligible. The proximal end of the stent was placed in such a way as to avoid blocking the side branches, and the distal end was placed above the papilla when possible. Consecutive patients treated between April 2017 and January 2021 were retrospectively analyzed. The technical and functional success rates, rates and causes of recurrent biliary obstruction (RBO), time to RBO (TRBO), revision for RBO, and adverse events (AEs) were evaluated.

RESULTS

Eleven patients (Bismuth I/II/IIIa: 1/7/3) were enrolled. Two stents were placed in nine patients and three were placed in two patients. Both the technical and functional success rates were 100%. RBO occurred in four (36%) patients due to sludge formation. Revision was performed for three patients, with the successful removal of all stents. The median TRBO was 187 days, and no late AEs other than the RBO occurred. Regarding the distal position of the stent, the RBO rate was significantly lower (14.3% vs. 75%, p = 0.041) and the cumulative TRBO was significantly longer (median TRBO: not reached vs. 80 days, p = 0.031) in the case of the placement above the papilla than the placement across the papilla.

CONCLUSION

For unresectable MHBOs of Bismuth I, II, and IIIa, whole-liver drainage with a novel 8 mm FCSEMS possessing an ultra-slim introducer was feasible and potentially safe, with favorable stent patency. Placement above the papilla might be preferrable to placement across the papilla.

Abstract

BACKGROUND

Percutaneous bilateral biliary stenting is an established method for the management of unresectable malignant hilar biliary obstruction.

AIM

To evaluate the efficacy and safety of a novel uncovered biliary stent, specifically designed for hilar reconstruction.

METHODS

This, single-center, retrospective study included 18 patients (mean age 71 ± 11 years; 61.1% male) undergoing percutaneous transhepatic Moving cell stent (MCS) placement for hilar reconstruction using the stent-in-stent technique for malignant biliary strictures, between November 2020 and July 2021. The Patients were diagnosed with cholangiocarcinoma (12/18; 66.6%), gallbladder cancer (5/18; 27.7%), and colorectal liver metastasis (1/18; 5.5%). Primary endpoints were technical (appropriate stent placement) and clinical (relief from jaundice) success. Secondary endpoints included stent patency, overall survival, complication rates and stent-related complications.

RESULTS

The technical and clinical success rates were 100% (18/18 cases). According to Kaplan-Meier analysis, the estimated overall patient survival was 80.5% and 60.4% at 6 and 12 mo respectively, while stent patency was 90.9% and 68.2% at 6 mo and 12 mo respectively. The mean stent patency was 172.53 ± 56.20 d and median stent patency was 165 d (range 83-315). Laboratory tests for cholestasis significantly improved after procedure: mean total bilirubin decreased from 15.2 ± 6.0 mg/dL to 1.3 ± 0.4 mg/dL (P < 0.001); mean γGT decreased from 1389 ± 832 U/L to 114.6 ± 53.5 U/L (P < 0.001). One periprocedural complication was reported. Stent-related complications were observed in 5 patients (27.7%), including 1 occlusion (5.5%) and 1 stent migration (5.5 %).

CONCLUSION

Percutaneous hilar bifurcation biliary stenting with the MCS resulted in excellent clinical and technical success rates, with acceptable complication rates. Further studies are needed to confirm these initial positive results.

Abstract

BACKGROUND

Patients with malignant hilar biliary strictures can suffer from obstructive jaundice. Controversy remains on the optimal approach to obtain preoperative or palliative biliary drainage in these patients. A systematic review and meta-analysis was conducted to compare the two modalities most commonly used in this scenario: endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC).

METHODS

MEDLINE via PubMed was searched for relevant articles published from 2005 to April 2019. Following outcome measures were used to compare ERCP and PTC: therapeutic success rate, cholangitis, pancreatitis, bleeding, tube dislocation, reintervention rate, mortality such as 30d mortality and in-hospital death, median survival time, drainage patency, duration until decompression and hospital stay. Risk of bias assessment for the retrospective studies was conducted by NOS. RoB 2 was used for RCT. A meta-analysis was performed by using Review Manager 5.3. The certainty of evidence was appraised using GRADE.

RESULTS

Eleven articles of which one RCT and ten retrospective cohort studies fulfilled the inclusion criteria for data-analysis (1417 patients; 784 ERCP, 633 PTC). The combined odds ratio (OR) for therapeutic succes was 3.5 times higher in the PTC group (95% CI 2.05-5.97; high certainty). In terms of cholangitis, ERCP carried a 1.7-fold risk as compared to PTC (95% CI 0.92-3.08; moderate certainty). Patients who underwent ERCP were 11.50 times more likely to undergo a reintervention (95% CI 3.51-37.70; moderate certainty). ERCP was comparable to PTC in terms of pancreatitis (low certainty), bleeding (high certainty) and tube dislocation rate (moderate certainty). Mortality tended to be numerically higher in the PTC group but low patient numbers, selection bias and study heterogeneity did not allow uniform comparative analysis.

CONCLUSIONS

In patients with malignant hilar biliary strictures, PTC is associated with a better therapeutic success rate, less cholangitis and lower reintervention rate as compared to ERCP.

Abstract

This work aimed to investigate values of contrast-enhanced ultrasound (CEUS) under DEFLATE in the classification and diagnosis of the common bile duct and superficial lymphoid lesions. 88 patients with lower common bile duct lesions and 126 patients with superficial lymphoid lesions were selected as the subjects investigated and examined by CEUS under DEFLATE to compare characteristics and diagnostic efficiency of CEUS in different types of lesions. The time-intensity curve (TIC) was for quantitative analysis on CEUS results. The results showed that there were statistically significant differences in the comparison of time to peak (TTP), area under the curve (AUC), and gradient (Grad) of common bile duct walls in patients from the malignant group (P < 0.05), while the comparison of three indicators of patients in the benign group was not statistically remarkable (P > 0.05). In addition, there were statistically great differences in TTP, AUC, and Grad among patients in the benign and malignant groups (P < 0.05). The sensitivity, specificity, accuracy, and positive/negative predictive value of CEUS + ultrasound (US) in the diagnosis of benign and malignant lymph nodes were 92.83%, 87.14%, 89.54%, 91.23%, and 86.43%, respectively. The values of maximal intensity (I_max) in the reactive hyperplasia group (group A), lymphoma group (group B), and metastatic lymph nodes group (group C) were compared, showing statistical differences (P < 0.05). The TTP and AUC of group B were higher than those of groups A and C, respectively (P < 0.05), and the base-to-peak ascending slope (K_UP) and the absolute value of the semidescending slope (K_DOWN) in group C increased hugely compared to group A (P < 0.05). It indicated that CEUS examination under DEFLATE could be applied in the qualitative diagnosis of lower common bile duct lesions and superficial lymphoid lesions, which was worthy of clinical application.

Abstract

BACKGROUNDS AND AIM

Multiple insertions of self-expandable metal stents (SEMS) for advanced malignant hilar obstruction (MHO) are now considered to be an effective palliative method for adequate drainage of liver volume. However, the efficacy of endoscopic reintervention in technically and clinically successful bilateral SEMS is limited. This study investigated the endoscopic revision efficacy in patients who underwent bilateral SEMS in MHO.

METHODS

Primary endoscopic revision using plastic or metal stents or an alternative percutaneous approach followed by secondary endoscopic revision was performed in patients who underwent clinically successful deployment of bilateral SEMS. The primary outcome was a technical success. Secondary outcomes were clinical success, adverse events, and patency duration after reintervention.

RESULTS

A total of 55 patients (83.3%) out of 66 enrolled patients underwent reintervention: primary endoscopic reintervention (n = 47) and secondary endoscopic revision following percutaneous drainage (n = 8). Intended technical success rates of primary and secondary endoscopic reintervention were 93.6% (44/47) and 87.5% (7/8), respectively (P = 0.47). Clinical success rates were 72.3% and 50%, respectively (P = 0.23). Stent malfunction rate after reintervention was 48.9% (23/47) and 37.5% (3/8) (P = 0.70) during follow up, and median cumulative stent patency duration was 119 and 55 days, respectively (log-rank P = 0.68). Stent patent rate after reintervention was not different according to the time interval. In univariate and multivariate analysis for stent patency duration-related factors after reintervention, there were no meaningful factors.

CONCLUSION

Primary endoscopic reintervention for bilateral SEMS in MHO was feasible technically and clinically. However, there were no statistically meaningful factors for stent patency duration after reintervention.
